Unraveling lexical semantics in the brain: Comparing internal, external, and hybrid language models.

To explain how the human brain represents and organizes meaning, many theoretical and computational language models have been proposed over the years, varying in their underlying computational principles and in the language samples based on which they are built. However, how well they capture the neural encoding of lexical semantics remains elusive. We used representational similarity analysis (RSA) to evaluate to what extent three models of different types explained neural responses elicited by word stimuli: an External corpus-based word2vec model, an Internal free word association model, and a Hybrid ConceptNet model. Semantic networks were constructed using word relations computed in the three models and experimental stimuli were selected through a community detection procedure. The similarity patterns between language models and neural responses were compared at the community, exemplar, and word node levels to probe the potential hierarchical semantic structure. We found that semantic relations computed with the Internal model provided the closest approximation to the patterns of neural activation, whereas the External model did not capture neural responses as well. Compared with the exemplar and the node levels, community-level RSA demonstrated the broadest involvement of brain regions, engaging areas critical for semantic processing, including the angular gyrus, superior frontal gyrus and a large portion of the anterior temporal lobe. The findings highlight the multidimensional semantic organization in the brain which is better captured by Internal models sensitive to multiple modalities such as word association compared with External models trained on text corpora.

Attitudes and perceptions of affected women towards endocrine endometriosis therapy: an international survey based on free-word association networks.

STUDY QUESTION: What are the attitudes and perceptions towards endocrine endometriosis therapy? SUMMARY ANSWER: Among the study population, endocrine endometriosis therapies are associated with negative mental images and emotions and there seems to be a pre-therapeutic information deficit on the part of physicians. WHAT IS KNOWN ALREADY: Endocrine therapies, as the current standard of conservative endometriosis treatment, have good efficacy and improve symptoms and quality of life in most patients. Nevertheless, clinical practice repeatedly shows rejection on the part of patients, which may result in reduced compliance and discontinuation of therapy. STUDY DESIGN, SIZE, DURATION: Cross-sectional study among endometriosis patients using a multilingual questionnaire distributed via the most popular social media channels between November 2020 and February 2021. A total of 3348 women participated in the study. PARTICIPANTS/MATERIALS, SETTING, METHODS: Based on a pilot phase, an international, multilingual online survey was conducted among women affected by endometriosis. The questionnaire included free-word associations and questions about personal medical history, source of information, and demographic data. Mental representations were detected based on modules of the co-occurrence network of associations. MAIN RESULTS AND THE ROLE OF CHANCE: Six modules with different dominant emotional labels emerged from the confluence of associations to endocrine endometriosis therapy mentioned by participants. Five modules reflected negative mental associations, with the most frequently mentioned words being 'side effects', 'pain', 'ineffective', 'depression', and 'uncertainty'. Of the 12 most frequently selected emotions, only 'optimistic' was positive. Side effects affecting mental health are the most important reason for deciding against endocrine therapy in our survey population. Twenty-seven percent of respondents reported knowing little about endocrine therapies for endometriosis. Social media are the most frequently used sources of information and were rated as the most useful. LIMITATIONS, REASONS FOR CAUTION: By translating the questionnaire, questions might have been understood differently depending on the language. By using social media channels for distribution, digitally literate patients were targeted. The survey population might not be representative as patients who are critical/unhappy with therapy are more likely to seek advice from peer groups. WIDER IMPLICATIONS OF THE FINDINGS: The findings of this study replicate the findings of a recent survey in three European countries. Given the prevalence of endometriosis and the few emerging pharmaceutical alternatives, these data point to a growing need for further research and development of non-hormonal drugs for treating endometriosis. Most endometriosis patients are young and digitally literate, and much information is obtained from alternative sources, such as social media. Careful education before starting therapy should be taken seriously, and patients' concerns should be addressed individually by health care providers. This could help reduce misunderstanding and misinformation and improve treatment adherence and satisfaction. STUDY FUNDING/COMPETING INTEREST(S): There is no funding or conflict of interest to declare. TRIAL REGISTRATION NUMBER: The trial is not registered at any trial registry.

The "Small World of Words" free association norms for Rioplatense Spanish.

Large-scale word association datasets are both important tools used in psycholinguistics and used as models that capture meaning when considered as semantic networks. Here, we present word association norms for Rioplatense Spanish, a variant spoken in Argentina and Uruguay. The norms were derived through a large-scale crowd-sourced continued word association task in which participants give three associations to a list of cue words. Covering over 13,000 words and +3.6 M responses, it is currently the most extensive dataset available for Spanish. We compare the obtained dataset with previous studies in Dutch and English to investigate the role of grammatical gender and studies that used Iberian Spanish to test generalizability to other Spanish variants. Finally, we evaluated the validity of our data in word processing (lexical decision reaction times) and semantic (similarity judgment) tasks. Our results demonstrate that network measures such as in-degree provide a good prediction of lexical decision response times. Analyzing semantic similarity judgments showed that results replicate and extend previous findings demonstrating that semantic similarity derived using spreading activation or spectral methods outperform word embeddings trained on text corpora.

A supposedly objective thing I'll never use again: Word association and the quest for validity and reliability in emotional adjustment research from Carl Jung to Carl Rogers (1898-1927).

As the first two decades of the 20th century unfolded, clinical psychologists, who had until then been mainly associated with intelligence testing, attempted to implement a specific psychological method-Carl Gustav Jung's (1875-1961) word-association "test"-in individual personality assessments. As one of the early clinical psychologists who attempted to use the method, Carl Ransom Rogers (1902-1987) is conspicuously absent from the historiography of clinical psychological testing. In fact, historians have recently suggested that we are lacking narratives about Rogers' early ideas and techniques in the context of both the development of clinical psychology and the emergence of psychological testing as clinicians' foremost scholarly activity. In light of the above, this paper pursues two main goals. First, it attempts to reconstruct Rogers' first original research project on emotional adjustment testing in young children in the broader context of the development of word-association tests as carried out by Jung and Whately Smith (1892-1947). Second, it aims to reconstruct Rogers' earliest theoretical ideas as well as his epistemological assumptions regarding test objectivity, validity and reliability. By drawing on unpublished documents and heretofore overlooked primary sources I show that although Rogers initially drew from Jung and Smith's complex and refined tradition, he ultimately rejected it as well as the tests themselves. At first drawn to Smith's quantitative, empiricist and experimental philosophy of psychology, Rogers was deterred when the data gathered through his own research in 1927 suggested that word association tests had no real, effective clinical value when used in children. By showcasing the complex process of test construction and validation undertaken by 1920s clinical psychologists, Rogers' case illustrates the research practices, the methodological problems and the epistemological dilemmas faced by most if not all of his contemporaries.

Diagnosis, knowledge, perception, and productivity impact of headache education and clinical evaluation program in the workplace at an information technology company of more than 70,000 employees.

BACKGROUND: Migraine is a highly prevalent, disabling, misunderstood, underdiagnosed, and undertreated neurological disease. It is a leading cause of productivity loss in the workplace. METHODS: This is the first large-scale company-wide headache education and evaluation program in the workplace. RESULTS: 73,432 (90.5%) Fujitsu employees participated. The prevalence of migraine was 16.7%, tension-type headache 40.7%, and cluster headache 0.5%. After completing the training, 82.9% of participants without headache said they would change their attitude towards colleagues with headache disorders and 72.5% of total participants said their understanding of headache changed. The proportion of employees who thought that headache had a significant impact on people's lives increased from 46.8% to 70.6%; 2971 (4.1%) of all participants were interested in a virtual consultation with a headache specialist as part of the program, more than half of whom had not previously consulted for headache. Approximately 14.7 days per year of full productivity per employee with headache were gained resulting in an annual productivity saving per employee of US$4531. CONCLUSION: This unique headache workplace program was associated with a high level of participation, an improvement in the understanding of migraine and attitude towards colleagues with migraine, reduction in disability and increased employee productivity, and decreased costs of lost productivity due to migraine. Workplace programs for migraine should be considered for all industry sectors.

Dimensions of food-related wellbeing and their relative importance among New Zealand consumers: A quasi-replication and extension approach.

Research into perceived wellbeing (WB) can improve understanding of consumer food choices and support development of strategies to promote healthier and more sustainable eating habits. In this research, using online studies, food-related WB was explored among New Zealand consumers. In a "quasi-replication" of Jaeger, Vidal, Chheang, and Ares (2022), Study 1 uncovered word associations to different WB-related terms ('Sense of wellbeing,' 'Lack of wellbeing,' 'Feeling good,' 'Feeling bad/unhappy,' 'Satisfied with life,' and 'Dissatisfied with life') with 912 participants in a between-subjects design. The results confirmed the multidimensional nature of WB, and the need to consider positive and negative aspects of food-related WB, as well as differences linked to physical, emotional, and spiritual WB. Drawing on Study 1, 13 characteristics of food-related WB were identified, and in Study 2 their importance for feeling a 'Sense of wellbeing' and 'Satisfied with life' was determined with 1206 participants using a between-subjects design. In a further extension, Study 2 also adopted a product-specific perspective and explored the associations of, and importance, for 16 different foods and beverages to food-related WB. Based on Best-Worst Scaling and penalty/lift analysis, the four most important characteristics overall were 'Is good quality,' 'Is healthy,' 'Is fresh,' and 'Is tasty,' with the nuance that healthiness contributed most to feeling a 'Sense of wellbeing' while good quality contributed most to feeling 'Satisfied with life.' The associations to individual foods and beverages underscored that food-related WB is a complex construct arising from an overall evaluation of the different effects of foods (including physical health, social and spiritual aspects of food consumption) and their short-term effects on food-related behaviour. Contextual and individual differences in perceptions of WB in relation to food deserve further investigation.

Updating and pre-existing semantic associations: testing can enhance or impair new learning.

We often need to update what we have learned, building on older information by adding newer information. When updating, is it better to review the older information by retrieving it (testing) or restudying it? In other words, do tests result in enhanced updating or impaired updating compared to restudying? Past research has obtained divergent conclusions to this question. The present study used a paired associates updating paradigm in which participants studied a cue and the older response (A-B). They later reviewed the older response by restudying (A-B) or testing (A-?; A-B) and immediately after learned a newer response (-D) that updated the original pair into a trio (A-B-D). In eight experiments, we demonstrated that different patterns of pre-existing semantic associations between the cue, older response, and newer response resulted in all possible outcomes: test enhanced new learning, test impaired new learning, and no difference. The results were most consistent with a family of updating theories that propose the metacognitive processes that occur after reviewing determine whether testing enhances, impairs, or has no impact on new learning. The results suggest that theories should consider the impact of the newer response in updating in addition to performance on the initial test.

Appraising Unmet Needs and Misinformation Spread About Polycystic Ovary Syndrome in 85,872 YouTube Comments Over 12 Years: Big Data Infodemiology Study.

BACKGROUND: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women, resulting in substantial burden related to metabolic, reproductive, and psychological complications. While attempts have been made to understand the themes and sentiments of the public regarding PCOS at the local and regional levels, no study has explored worldwide views, mainly due to financial and logistical limitations. YouTube is one of the largest sources of health-related information, where many visitors share their views as questions or comments. These can be used as a surrogate to understand the public's perceptions. OBJECTIVE: We analyzed the comments of all videos related to PCOS published on YouTube from May 2011 to April 2023 and identified trends over time in the comments, their context, associated themes, gender-based differences, and underlying sentiments. METHODS: After extracting all the comments using the YouTube application programming interface, we contextually studied the keywords and analyzed gender differences using the Benjamini-Hochberg procedure. We applied a multidimensional approach to analyzing the content via association mining using Mozdeh. We performed network analysis to study associated themes using the Fruchterman-Reingold algorithm and then manually screened the comments for content analysis. The sentiments associated with YouTube comments were analyzed using SentiStrength. RESULTS: A total of 85,872 comments from 940 PCOS videos on YouTube were extracted. We identified a specific gender for 13,106 comments. Of these, 1506 were matched to male users (11.5%), and 11,601 comments to female users (88.5%). Keywords including diagnosing PCOS, symptoms of PCOS, pills for PCOS (medication), and pregnancy were significantly associated with female users. Keywords such as herbal treatment, natural treatment, curing PCOS, and online searches were significantly associated with male users. The key themes associated with female users were symptoms of PCOS, positive personal experiences (themes such as helpful and love), negative personal experiences (fatigue and pain), motherhood (infertility and trying to conceive), self-diagnosis, and use of professional terminology detailing their journey. The key themes associated with male users were misinformation regarding the "cure" for PCOS, using natural and herbal remedies to cure PCOS, fake testimonies from spammers selling their courses and consultations, finding treatment for PCOS, and sharing perspectives of female family members. The overall average positive sentiment was 1.6651 (95% CI 1.6593-1.6709), and the average negative sentiment was 1.4742 (95% CI 1.4683-1.4802) with a net positive difference of 0.1909. CONCLUSIONS: There may be a disparity in views on PCOS between women and men, with the latter associated with non-evidence-based approaches and misinformation. The improving sentiment noticed with YouTube comments may reflect better health care services. Prioritizing and promoting evidence-based care and disseminating pragmatic online coverage is warranted to improve public sentiment and limit misinformation spread.

Impact of therapeutic education on the evolution of social representations of medication in patients with Parkinson's disease: A quantitative and qualitative study (ETPARK REMED).

BACKGROUND: Among the workshops of our therapeutic patient education (TPE) program, the medication workshop (TPEM workshop) is very frequently proposed to patients in view of the difficulties they encounter related to the complexity of managing antiparkinsonian treatment. Patients' appropriation of their medications could depend on their social representations. OBJECTIVES: To evaluate the effect of our TPEM workshop on the social representations PD patients have of their medications and to compare it with that of another therapeutic intervention such as a talking group defined as the control group. METHODS: This single-center, prospective, randomized, parallel-group study investigated the social representations of medication through a questionnaire on knowledge about antiparkinsonian medications, a questionnaire on beliefs about medication (BMQ), and a word association task. RESULTS: In the TPEM group (n=16), the workshop induced significant effects over time on the knowledge questionnaire (P=0.01), BMQ specific necessity and concerns scores (P=0.04 and 0.01, respectively), necessity-concerns differential (P=0.04), and BMQ general harm (P=0.04). No significant difference was found in the talking group (n=6). Comparison of the two groups showed a significant difference of the BMQ general harm with a decrease in belief in the harmfulness of the medications in the workshop group (P=0.03). The results of the verbal association task showed a modification in the content and structure of the social representations of medication in the TPEM group. DISCUSSION: The TPEM workshop helped reduce initial negative aspects of medication representations. Improved knowledge of their medication allowed patients to feel more competent and legitimate in communicating with caregivers, modifying their beliefs about medications. Indeed, the medication was perceived as less restrictive, care becoming central as shown by the emergence of the medical team in the social representations of the medication. CONCLUSION: All the results show a specific beneficial effect of the TPEM workshop through an evolution of the social representations of medications, which became more positive in our PD patients.

Chinese College Students' Death Cognition and its Long-Term Changes After Wenchuan Earthquake.

This study explores the cognitive structure of death and long-term changes of death cognition after catastrophes for Chinese college students. Two months before Wenchuan earthquake, a week after, a year after, and ten years after, a total of 1507 participants' associated words of death were collected, after clustering high-frequency words' similarity coefficients, results showed that death was represented by four advanced clusters: death contact, death anxiety and its reminders, deathafter, and defense mechanism; a week after earthquake, death anxiety and its reminders, defense mechanism were activated; a year after, death contact, afterdeath were appreciated, death anxiety and its reminders, defense mechanism were underappreciated, this phenomenon still existed even ten years later, which suggests that the earthquake permanently changed their death cognition, and this change stabilized one year later. In addition, this paper provides an effective method to uncover cognitive structure of one certain concept.

Consumer conceptualisations of food-related wellbeing: An exploration of wellbeing-related terms in four industrialised countries.

Perceived (or subjective) wellbeing is regarded as key to understanding consumer food choices and the development of strategies to promote desirable eating habits. Yet, in-depth understanding of the specific factors that contribute to people's perceived wellbeing across cultures is lacking. These factors motivated the present research that used word associations to conduct an exploratory analysis of consumer conceptualisations of food-related wellbeing (WB). Adults (n = 4945) living in the United Kingdom, Australia, Singapore or Germany, and speaking respectively, English or German, took part in the study. Health, pleasure, food quality, positive emotions and social aspects of food consumption were the main associations with food-related wellbeing. Absence hereof was associated with unhealthiness, disgust, negative emotions and poor mental health. The differences in these main associations emphasised the importance of exploring wellbeing, as well as lack hereof. Not doing so leads to an incomplete understanding of this multidimensional construct. The research was conducted with four terms related to wellbeing (each in their positive and negative versions): 'sense of wellbeing' and 'lack of wellbeing', 'feeling good' and 'feeling bad/unhappy', 'satisfied with life' and 'dissatisfied with life' and 'fulfilled in life' and 'unfulfilled in life'. Because these different terms gave rise to different wellbeing associations, researchers in this area must choose their empirical approach with care. The terms 'sense of wellbeing' and 'feeling good' tended to more frequently give rise to health-related associations. Conversely, 'satisfied with life' and 'fulfilled in life' tended to more frequently give rise to positive spiritual and emotional associations of food-related wellbeing. The main conceptualisations of food-related wellbeing were cross-culturally similar, but extension of the present research to other Asian countries was recommended based on several differences between Singaporean participants and those from other countries. In ethnically diverse countries like Singapore, further within-country investigations of different cultures will also have merit.

"Food made with edible insects": Exploring the social representation of entomophagy where it is unfamiliar.

Insects have attracted much attention as a novel food source because of their environmental and nutritional advantages. In Latin America, some traditional groups consume insects; but the urban areas of Brazil resist adopting insects as food, like most Western countries. Thus, this study investigated the social representation of edible insects to understand the barrier behind this avoidance and to identify their segmentation in the Brazilian population. Seven hundred and eighty individuals were interviewed in all the Brazilian regions. The interview was composed of a word association task, a risk perception evaluation and two open-ended questions about the subject. According to the structural approach of social representation, Disgust was the primary association with edible insects. Three segments of consumers were identified using the risk perception of eating insects. The first segment, composed mainly of young men with higher educational levels, had the lowest risk perception, and the most positive attitude about entomophagy, their associations were also positive, such as Acceptance and Sustainability; the second had average risk perception and neutral attitude towards edible insects, with neutral and positive associations (e.g., Flavor and Culture); and the third, formed mostly by older women with lower educational level, presented the highest risk perception and the most negative attitude, and exhibited negative associations (Disgust, and Fear). The insect consumption in Brazil would be favored by using species of crickets, grasshoppers, ants, and their fried and roasted styles of preparations. Also, participants would eat insects mainly because of survival and curiosity.

Progressive retrieval practice leads to greater memory for image-word pairs than standard retrieval practice.

The benefits of retrieval practice on learning are robust and have transferred from laboratory findings to many real-world educational settings. We report two experiments that investigated a novel retrieval practice technique for remembering arbitrary associations (image-word pairs), with and without reward as a motivator. As well as typical retrieval practice and restudy conditions, we added a third condition of graded retrieval practice in which the image cue was partially released in a progressive process. Experiment 1 found significant benefits of retrieval practice over restudy, with an additional benefit of graded retrieval practice compared with standard retrieval practice after a 48-hour delay between study and retrieval. Experiment 2 included a reward manipulation by giving participants money based on their memory performance. The findings replicated the retrieval practice effects observed in Experiment 1, including a robust advantage for graded retrieval practice. Reward neither changed the additive advantage of graded recall nor the benefit of retrieval practice. The present study adds to the literature indicating that retrieval with progressive retrieval cues can boost the benefit of retrieval practice by generating repeated retrieval attempts. This benefit occurs most for items that are neither too easy nor too challenging to retrieve.

NIRS Studies Show Reduced Interhemispheric Functional Connectivity in Individuals with Multiple Sclerosis That Exhibit Cortical Hypoxia.

Many with multiple sclerosis (MS) have low cortical microvascular oxygen levels (hypoxia), which have been previously proposed to exacerbate inflammation in MS. We do not know if hypoxia impacts or relates to brain function. We hypothesise that within the MS population, those who have hypoxia may show reduced brain functional connectivity (FC). We recruited 20 MS participants and grouped them into normoxic and hypoxic groups (n = 10 in each group) using frequency-domain near-infrared spectroscopy (fdNIRS). Functional coherence of the haemodynamic signal, quantified with functional near-infrared spectroscopy (fNIRS) was used as a marker of brain function and was carried out during resting-state, finger-tapping, and while completing two neurocognitive tasks. Reduced FC was detected in the hypoxic MS group. fNIRS measures of haemodynamic coherence in MS could be a biomarker of functional impairment and/or disease progression.

Satiety and consumers' perceptions: What opinions do Argentinian and Brazilian people have about yogurt fortified with dairy and legume proteins?

This study (1) evaluated the perceptions of Argentinian and Brazilian consumers regarding yogurt fortified with dairy proteins, legume proteins, or a combination of both, and (2) determined the satiety expectations of these foods as well as the consumers' intentions to taste and purchase protein-fortified yogurt. A total of 298 Argentinian and 100 Brazilian participants completed an online survey for this study. The free word association technique was used to investigate their perceptions about "satiety" as a verbal stimulus and 6 concepts of yogurt as visual/verbal stimuli (yogurt, set yogurt, skim set yogurt, skim set yogurt with a high content of dairy proteins, skim set yogurt with a high content of legume proteins, and skim set yogurt with a mix of dairy and legume proteins). The expected satiation and intentions to taste or purchase were evaluated using categorical scales. Regardless of their cultural background, participants from both countries expressed similar associations with the stimuli presented. Yogurt and set yogurt were associated with consumption occasions, sensory characteristics, liking, and foods, whereas skim yogurt was associated with diet food. Products fortified with proteins were associated with healthy foods, regardless of the protein source, and they yielded the highest rates for expected satiation. Brazilian participants were more likely to taste the food with a combination of proteins; however, participants from both countries were indifferent to purchasing the product. Important characteristics in the design and marketing of these products were pleasant sensations, such as "fullness," "satisfied," and snacks to eat "on the go," and the vegetarian consumers' segment. The combination with fruits or cereals, creaminess, and vanilla flavor should also be considered. The study findings could have implications for the dairy industry when designing yogurt fortified with proteins and communicating the nutritional and wholesome properties of these products.

The neural underpinnings of allocentric thinking in a novel signaling task.

The ability to adopt the perspectives of others is fundamental to effective communication in social interactions. However, the neural correlates of allocentric thinking in communicative signaling remain unclear. We adapted a novel signaling task in which the signaler was given the target word and must choose a one-word signal to help the receiver guess the target. Behavioral results suggest that speakers can use allocentric thinking to choose signals that are salient from the perspective of the receiver rather than their own point of view. At the neural level, functional magnetic resonance imaging (fMRI) data reveal that the medial prefrontal cortex (mPFC), ventral striatum, and temporal-parietal junction are more activated when signalers engage in allocentric than egocentric thinking. Moreover, functional connectivity between the mPFC and ventral striatum predicted individuals' perspective-taking ability during successful communication. These findings reveal that neural representations in the mPFC-striatum network support perspective-taking in complex social decision making, providing a new perspective on how the brain arbitrates between allocentric thinking and egocentric thinking in communication and social coordination.

The social representations of complementary feeding.

The social representations of complementary feeding are expected to shape parents' decisions and to provide justification or legitimization for their practices. The aims of the present work were: i) to explore the social representations of complementary feeding in parents and health professionals, ii) to evaluate if the onset of complementary feeding modify social representations in parents, and iii) to compare the representations of parents and pediatricians. Three groups of participants were considered: 170 parents of children who had not started complementary feeding (1-4 months old), 170 parents of children who had started complementary feeding (7-10 months old) and 212 pediatricians. Parents were recruited in health facilities in Montevideo (Uruguay), whereas pediatricians were recruited at the National Pediatrics Conference. Participants were asked to complete a word association task with "the first meals of a baby". All the responses provided by participants were grouped into categories using content analysis. The structure of the social representations was assessed considering the frequency of mention and the average rank of appearance of the categories. Results showed that the social representations of complementary feeding for both parents and pediatricians were extremely narrow and mainly focused on specific foods: puree and a small set of vegetables and fruits. None of the categories showed high frequency of mention and low rank of appearance, indicating that the structure of the social representations did not include any element in the first periphery. According to the theory of social representations, results from the present work suggest that the social representations of complementary feeding for Uruguayan parents and pediatricians are deeply rooted and resistant to change.

Automating creativity assessment with SemDis: An open platform for computing semantic distance.

Creativity research requires assessing the quality of ideas and products. In practice, conducting creativity research often involves asking several human raters to judge participants' responses to creativity tasks, such as judging the novelty of ideas from the alternate uses task (AUT). Although such subjective scoring methods have proved useful, they have two inherent limitations-labor cost (raters typically code thousands of responses) and subjectivity (raters vary on their perceptions and preferences)-raising classic psychometric threats to reliability and validity. We sought to address the limitations of subjective scoring by capitalizing on recent developments in automated scoring of verbal creativity via semantic distance, a computational method that uses natural language processing to quantify the semantic relatedness of texts. In five studies, we compare the top performing semantic models (e.g., GloVe, continuous bag of words) previously shown to have the highest correspondence to human relatedness judgements. We assessed these semantic models in relation to human creativity ratings from a canonical verbal creativity task (AUT; Studies 1-3) and novelty/creativity ratings from two word association tasks (Studies 4-5). We find that a latent semantic distance factor-comprised of the common variance from five semantic models-reliably and strongly predicts human creativity and novelty ratings across a range of creativity tasks. We also replicate an established experimental effect in the creativity literature (i.e., the serial order effect) and show that semantic distance correlates with other creativity measures, demonstrating convergent validity. We provide an open platform to efficiently compute semantic distance, including tutorials and documentation ( https://osf.io/gz4fc/ ).

Tarvajeh: Word Association Norms for Persian Words.

In recent years, word associations have played a key role in cognitive research. The goal of this study is to propose a new system called Tarvajeh to construct and analyze the association norms found in the Persian language. In this paper, we present Tarvajeh, a data set for Persian words in a continuous word association task. For data collection, cue words have been categorized into groups and then, 30 of them were presented to each participant in two phases. Afterward, the participants were asked to write the first three words that are related to the initial cue words. After data collection, Tarvajeh included 240 frequent Persian cues and more than 20,000 different responses. Furthermore, we also propose a method that allows participants to compare their responses as well as their subconscious mind with those of their peers using a unique graph that is tailored to their responses and is displayed to them. Finally, we compared our data with those of associated words in other languages. The comparison reveals that, for some cues, most associated words are the same, while for others, the most frequent responses are unique within each data set. In addition, some gender-related differences were observed with male participants spending more time on their responses than female participants.

Testing the specificity of interpretation biases in women with eating disorder symptoms: An online experimental assessment.

OBJECTIVE: Cognitive biases, such as memory, attention, and interpretation bias, are thought to play a central role in the development and maintenance of eating disorders (EDs). The aim of the present study was to investigate whether the interpretation bias is ED-specific or can be generalized to comorbid disorder-related threats in women with high levels of ED symptoms. METHOD: In an online study, we measured interpretation bias using the modified Sentence Word Association Paradigm (SWAP), comparing women with (n = 39) and without (sub)threshold eating disorders (n = 56). We assessed endorsement and rejection rates as well as reaction times in response to a positive/neutral or a negative ED-specific, social anxiety-specific (SAD), or generalized anxiety-specific (GAD) interpretive word following an ambiguous sentence. RESULTS: In ambiguous situations, women with high ED symptoms selected more negative (p < .001) and fewer positive/neutral ED-related interpretations (p < .001). Negative interpretations were endorsed significantly faster (p < .001), while positive interpretations were rejected faster in this group (p < .001). These women also manifested negative SAD-specific interpretation bias patterns in reaction time measures. Nevertheless, ED severity was best predicted by the endorsement of negative ED-specific stimuli, whereas ED and SAD reaction time measures seemed to have a negligible effect. DISCUSSION: The results indicate that the interpretation bias might be ED-specific. The SWAP can be a useful tool for the further investigation of the etiological relevance of the interpretation bias as well as for the development of modification training interventions.
