RESUMO

Models of word meaning that exploit patterns of word usage across large text corpora to capture semantic relations, like the topic model and word2vec, condense word-by-context co-occurrence statistics to induce representations that organize words along semantically relevant dimensions (e.g., synonymy, antonymy, hyponymy, etc.). However, their reliance on latent representations leaves them vulnerable to interference, makes them slow learners, and commits to a dual-systems account of episodic and semantic memory. We show how it is possible to construct the meaning of words online during retrieval to avoid these limitations. We implement a spreading activation account of word meaning in an associative net, a one-layer highly recurrent network of associations, called a Dynamic-Eigen-Net, that we developed to address the limitations of earlier variants of associative nets when scaling up to deal with unstructured input domains like natural language text. We show that spreading activation using a one-hot coded Dynamic-Eigen-Net outperforms the topic model and reaches similar levels of performance as word2vec when predicting human free associations and word similarity ratings. Latent Semantic Analysis vectors reached similar levels of performance when constructed by applying dimensionality reduction to the Shifted Positive Pointwise Mutual Information but showed poorer predictability for free associations when using an entropy-based normalization. An analysis of the rate at which the Dynamic-Eigen-Net reaches asymptotic performance shows that it learns faster than word2vec. We argue in favor of the Dynamic-Eigen-Net as a fast learner, with a single-store, that is not subject to catastrophic interference. We present it as an alternative to instance models when delegating the induction of latent relationships to process assumptions instead of assumptions about representation.

RESUMO

Individuals are apt to link various characteristics of an object or event through different sensory experiences. We conducted two electrophysiological experiments to investigate the effects of color-flavor congruency and association strength on visual search efficiency and the in-depth cognitive mechanisms underlying multisensory processes. Participants were prompted with a flavor label and asked to identify the primed flavor from four beverage bottle images. Experiment 1 focused on color-flavor congruency and noted faster searches for congruent targets than incongruent ones. EEG data exhibited smaller N2, larger P3 and LPC, and increased parietal-occipital midline (POM) alpha power for incongruent targets than congruent ones. Experiment 2 manipulated color-flavor association strength within each flavor. Behavioral findings showed that searches for targets with weak association strength took longer than those with strong association strength. Moreover, time-frequency analysis displayed that the former evoked greater frontal midline (FM) theta power and higher alpha power than the latter. Altogether, our research indicated that (1) color expectations based on prior experience can automatically guide people's attentional selection, (2) the color-flavor congruency and association strength impact the visual search efficiency via distinct pathways, and (3) theta and alpha activities make a pivotal role in unraveling multisensory information processing. These findings shed some light on the intricate cognitive processes involved in crossmodal visual search and the underlying neurocognitive dynamics.

RESUMO

Alpha oscillations are known to play a central role in several higher-order cognitive functions, especially selective attention, working memory, semantic memory, and creative thinking. Nonetheless, we still know very little about the role of alpha in the generation of more remote semantic associations, which is key to creative and semantic cognition. Furthermore, it remains unclear how these oscillations are shaped by the intention to "be creative," which is the case in most creativity tasks. We aimed to address these gaps in two experiments. In Experiment 1, we compared alpha oscillatory activity (using a method which distinguishes genuine oscillatory activity from transient events) during the generation of free associations which were more vs. less distant from a given concept. In Experiment 2, we replicated these findings and also compared alpha oscillatory activity when people were generating free associations versus associations with the instruction to be creative (i.e. goal-directed). We found that alpha was consistently higher during the generation of more distant semantic associations, in both experiments. This effect was widespread, involving areas in both left and right hemispheres. Importantly, the instruction to be creative seems to increase alpha phase synchronisation from left to right temporal brain areas, suggesting that intention to be creative changed the flux of information in the brain, likely reflecting an increase in top-down control of semantic search processes. We conclude that goal-directed generation of remote associations relies on top-down mechanisms compared to when associations are freely generated.

RESUMO

Motion information has been argued to be central to the subjective segmentation of observed actions. Concerning object-directed actions, object-associated action information might as well inform efficient action segmentation and prediction. The present study compared the segmentation and neural processing of object manipulations and equivalent dough ball manipulations to elucidate the effect of object-action associations. Behavioral data corroborated that objective relational changes in the form of (un-)touchings of objects, hand, and ground represent meaningful anchor points in subjective action segmentation rendering them objective marks of meaningful event boundaries. As expected, segmentation behavior became even more systematic for the weakly informative dough. fMRI data were modeled by critical subjective, and computer-vision-derived objective event boundaries. Whole-brain as well as planned ROI analyses showed that object information had significant effects on how the brain processes these boundaries. This was especially pronounced at untouchings, that is, events that announced the beginning of the upcoming action and might be the point where competing predictions are aligned with perceptual input to update the current action model. As expected, weak object-action associations at untouching events were accompanied by increased biological motion processing, whereas strong object-action associations came with an increased contextual associative information processing, as indicated by increased parahippocampal activity. Interestingly, anterior inferior parietal lobule activity increased for weak object-action associations at untouching events, presumably because of an unrestricted number of candidate actions for dough manipulation. Our findings offer new insights into the significance of objects for the segmentation of action.

RESUMO

Investigating how infants first establish relationships between words is a necessary step towards understanding how an interconnected network of semantic relationships develops in the adult lexical-semantic system. Stimuli selection for these child studies is critical since words must be both familiar and highly imageable. However, there has been a reliance on adult word association norms to inform stimuli selection in English infant studies to date, as no resource currently exists for child-specific word associations. We present three experiments that explore the strength of word-word relationships in 3-year-olds. Experiment 1 collected children's word associations (WA) (N = 150; female = 84, L1 = British English) and compared them to adult associative norms (Moss & Older, 1996; Nelson et al., 2004 (Behavior Research Methods, Instruments, & Computers, 36(3), 402-407)). Experiment 2 replicated WAs from Experiment 1 in an online adaptation of the task (N = 24: 13 female, L1 = British English). Both experiments indicated a high proportion of child-specific WAs not represented in adult norms (Moss & Older, 1996; Nelson et al., 2004 (Behavior Research Methods, Instruments, & Computers, 36(3), 402-407)). Experiment 3 tested noun-noun WAs from these responses in an online semantic priming study (N = 40: 19 female, L1 = British English) and found that association type modulated priming (F(2.57, 100.1) = 13.13, p <. 0001, generalized η2 = .19). This research presents a resource of child-specific imageable noun-noun word pair stimuli suitable for testing young children in word recognition and semantic priming studies.

RESUMO

We introduce the test difficulty concept from classical test theory to tackle the issue of low predictive power of implicit association tests (IATs). Following classical test theory, we argue that IATs of moderate difficulty (defined as mean IAT scores of zero) have more predictive power than IATs of extreme difficulties (defined as mean IAT scores deviating strongly from zero). Furthermore, we assume this relationship to be mediated by the true-score variance in IAT scores, with moderate difficulty resulting in more true-score variance. To test our hypotheses, we used nonexperimental (Studies 1 and 2) and experimental designs (Study 3). In Studies 1 and 2, we compared IATs of different test difficulties with regard to their ability to predict direct attitude measures, drawing on the Attitudes, Identities, and Individual Differences study. In Study 1, a subset of 95 attitude IATs (n = 127,259) was analyzed using multilevel structural equation models. As expected, IAT test difficulty strongly moderated the predictive power of IATs, and this effect was mediated by IAT true-score variance. In Study 2, we replicated the results with the same analyses but a different subset of 95 identity IATs (n = 43,745). In Study 3, we experimentally manipulated the IAT test difficulty. In total, three IATs (n = 480) were analyzed using multigroup structural equation models. Again, the IAT closer to moderate difficulty had more true-score variance and predictive power than the IATs of extreme difficulty. Accordingly, for correlational research, we recommend developing moderately difficult IATs to maximize IAT true-score variance and provide suggestions on how to achieve that.

RESUMO

The efficacy of explicit measures in assessing fire interest is often compromised by social desirability biases, presenting a challenge for early intervention programs aimed at preventing firesetting behaviour. The current study aimed to validate a novel fire interest Implicit Association Task (IAT), as a more reliable measure of implicit fire interest in adolescents. An Australian community adolescent sample of 85 participants, aged 10-17 (M = 13.65, SD = 1.81), completed a series of questionnaires, and the novel fire interest IAT. Based on self-reports, participants were classified as firelighters (n = 52) or non-firelighters (n = 33). IAT outcomes revealed an inclination towards associating "fire" with "interesting." Notably, firelighters, compared to non-firelighters, performed significantly quicker during hypothesis-consistent trials of the IAT where fire-images were paired with interesting-words. Moreover, a weak correlation emerged between the speed of responses in these hypothesis-consistent IAT trials and self-reported fire interest. This investigation is one of the few that examined the efficacy of implicit measures of fire interest and is the first to do so using a modified IAT. With continued refinement, the fire interest IAT could be successfully used to assist with early intervention programs aimed at preventing child firesetting behaviour. PsychINFO Code: 3230.

RESUMO

BACKGROUND AND OBJECTIVES: Children of parents with an anxiety disorder are at elevated risk for developing an anxiety disorder themselves. According to cognitive theories, a possible risk factor is the development of schema-related associations. This study is the first to investigate whether children of anxious parents display fear-related associations and whether these associations relate to parental anxiety. METHODS: 44 children of parents with panic disorder, 27 children of parents with social anxiety disorder, and 84 children of parents without an anxiety disorder filled out the SCARED-71, and the children performed an Affective Priming Task. RESULTS: We found partial evidence for disorder-specificity: When the primes were related to their parent's disorder and the targets were negative, the children of parents with panic disorder and children of parents with social anxiety disorder showed the lowest error rates related to their parents' disorder, but they did not have faster responses. We did not find any evidence for the expected specificity in the relationship between the parents' or the children's self-reported anxiety and the children's fear-related associations, as measured with the APT. LIMITATIONS: Reliability of the Affective Priming Task was moderate, and power was low for finding small interaction effects. CONCLUSIONS: Whereas clearly more research is needed, our results suggest that negative associations may qualify as a possible vulnerability factor for children of parents with an anxiety disorder.

RESUMO

We examined the allocation of visual attention in an association task by both neurotypical participants (n = 11) and adults with fluent aphasia (n = 12). Participants were presented with a picture (e.g., a basket) followed by a semantically related association (i.e., "strawberry") and an orthographically related association (i.e., "b," the first letter of "basket"). An eye tracker recorded their eye movements for three areas of interest (AOI): the picture, the semantic associate, and the orthographic associate, over 1396 observations. Results showed that both neurotypical participants and participants with aphasia looked longer at the semantic associate than at the picture, and this difference was more pronounced for neurotypicals than for people with aphasia (PWA). Neurotypicals also looked longer than the PWA group at the orthographic associate than at the prior picture. Regarding eye fixation counts, both participant groups looked more frequently at the semantic associate than at either the picture or the orthographic associate. Notably, this pattern was more pronounced among neurotypical participants than PWA. Our findings emphasize the importance of semantic associations in fluent aphasia and suggest a potential rehabilitative approach in speech and language therapy.

RESUMO

During conversations, people face a trade-off between establishing understanding and making interesting and unique contributions. How do people balance this when deciding which concepts to reference, and does it matter how well they know their conversation partner? In the present work, participants made stream-of-consciousness word associations either with a partner or alone-simplified versions of dialogue and monologue. Participants made semantically narrower and more predictable word associations with a stranger than alone (Study 1), suggesting that they constrain their associations to establish mutual understanding. Increasing closeness (Study 2) or having a prior relationship (Study 3) did not moderate this effect. Thus, even during a task that does not depend on establishing mutual understanding, people sacrifice being interesting for the sake of being understood.

RESUMO

Abstract Introduction As 30 to 50% of deep venous thrombosis (DVT) cases remain idiopathic, an increased focus on hematologic variables may therefore reveal novel correlates of DVT. Very few studies have investigated the association of hematological parameters with DVT and the causal relationship between them is still to be elucidated. Therefore, we aimed to investigate the association between serial values of hematologic variables and DVT. Methods Complete blood count parameters were serially measured at baseline and then at approximately 3-month intervals for 12 months in 152 adults with the first episode of DVT and 152 age- and sex-matched controls. The odds ratio (OR) with the 95% confidence interval (95%CI) was calculated as a measure of association between hematological parameters and DVT. Results The red cell distribution width (RDW) was the only hematologic variable which showed an independent and consistent association with DVT at all time points (multivariable-adjusted OR [95%CI] 3.38 [1.28 - 8.91] at baseline, 2.24 [0.85 - 5.92] at 3 months and 2.12 [0.81 - 5.55] at 12 months for RDW > 14.0%). This association was higher for provoked DVT than unprovoked DVT and for DVT plus pulmonary embolism than DVT alone. No significant correlation was found between the high RDW and classical thrombotic risk factors, except malignancy. Conclusions We demonstrated an independent and consistent association of the high RDW with the first episode of DVT in adult patients. The study was probably underpowered to evaluate the association between the high RDW and recurrent DVT. Further large studies with long follow-up are needed to confirm this association.

RESUMO

There is an increasing body of evidence suggesting that there are low-level perceptual processes involved in crossmodal correspondences. In this study, we investigate the involvement of the superior colliculi in three basic crossmodal correspondences: elevation/pitch, lightness/pitch, and size/pitch. Using a psychophysical design, we modulate visual input to the superior colliculus to test whether the superior colliculus is required for behavioural crossmodal congruency effects to manifest in an unspeeded multisensory discrimination task. In the elevation/pitch task, superior colliculus involvement is required for a behavioural elevation/pitch congruency effect to manifest in the task. In the lightness/pitch and size/pitch task, we observed a behavioural elevation/pitch congruency effect regardless of superior colliculus involvement. These results suggest that the elevation/pitch correspondence may be processed differently to other low-level crossmodal correspondences. The implications of a distributed model of crossmodal correspondence processing in the brain are discussed.

RESUMO

Over recent decades, studies investigating cross-modal correspondences have documented the existence of a wide range of consistent cross-modal associations between simple auditory and visual stimuli or dimensions (e.g., pitch-lightness). Far fewer studies have investigated the association between complex and realistic auditory stimuli and visually presented concepts (e.g., musical excerpts-animals). Surprisingly, however, there is little evidence concerning the extent to which these associations are shared across cultures. To address this gap in the literature, two experiments using a set of stimuli based on Prokofiev's symphonic fairy tale Peter and the Wolf are reported. In Experiment 1, 293 participants from several countries and with very different language backgrounds rated the association between the musical excerpts, images and words representing the story's characters (namely, bird, duck, wolf, cat, and grandfather). The results revealed that participants tended to consistently associate the wolf and the bird with the corresponding musical excerpt, while the stimuli of other characters were not consistently matched across participants. Remarkably, neither the participants' cultural background, nor their musical expertise affected the ratings. In Experiment 2, 104 participants were invited to rate each stimulus on eight emotional features. The results revealed that the emotional profiles associated with the music and with the concept of the wolf and the bird were perceived as more consistent between observers than the emotional profiles associated with the music and the concept of the duck, the cat, and the grandpa. Taken together, these findings therefore suggest that certain auditory-conceptual associations are perceived consistently across cultures and may be mediated by emotional associations.

RESUMO

Individuals make faster left responses to small/er numbers and faster right responses to large/r numbers than vice versa. This "spatial-numerical association of response codes" (SNARC) effect represents evidence for an overlap between the cognitive representations of number and space. Theories of the SNARC effect differ in whether they predict bidirectional S-R associations between number and space or not. We investigated the reciprocity of S-R priming effects between number and location in three experiments with vocal responses. In Experiments 1 and 2, participants completed a number-location task, with digits as stimuli and location words as responses, and a location-number task, with physical locations as stimuli and number words as responses. In addition, we varied the S-R mapping in each task. Results revealed a strong SNARC effect in the number-location task, but no reciprocal SNARC effect in the location-number task. In Experiment 3, we replaced physical location stimuli with location words and digit stimuli with number words. Results revealed a regular and a reciprocal SNARC effect of similar size. Reciprocal SNARC effects thus seem to emerge with verbal location stimuli and vocal responses, but not with physical location stimuli and vocal responses. The S-R associations underlying the SNARC effect with vocal responses thus appear bidirectional and symmetrical for some combinations of stimulus and response sets, but not for others. This has implications for theoretical accounts of the SNARC effect which need to explain how stimulus mode affects the emergence of reciprocal but not regular SNARC effects.

RESUMO

The Implicit Association Test (IAT, Greenwald et al., J. Pers. Soc. Psychol., 74, 1998, 1464) is a popular instrument for measuring attitudes and (stereotypical) biases. Greenwald et al. (Behav. Res. Methods, 54, 2021, 1161) proposed a concrete method for validating IAT stimuli: appropriate stimuli should be familiar and easy to classify - translating to rapid (response times <800 ms) and accurate (error < 10%) participant responses. We conducted three analyses to explore the theoretical and practical utility of these proposed validation criteria. We first applied the proposed validation criteria to the data of 15 IATs that were available via Project Implicit. A bootstrap approach with 10,000 'experiments' of 100 participants showed that 5.85% of stimuli were reliably valid (i.e., we are more than 95% confident that a stimulus will also be valid in a new sample of 18- to 25-year-old US participants). Most stimuli (78.44%) could not be reliably validated, indicating a less than 5% certainty in the outcome of stimulus (in)validity for a new sample of participants. We then explored how stimulus validity differs across IATs. Results show that only some stimuli are consistently (in)valid. Most stimuli show between-IAT variances, which indicate that stimulus validity differs across IAT contexts. In the final analysis, we explored the effect of stimulus type (images, nouns, names, adjectives) on stimulus validity. Stimulus type was a significant predictor of stimulus validity. Although images attain the highest stimulus validity, raw data show large differences within stimulus types. Together, the results indicate a need for revised validation criteria. We finish with practical recommendations for stimulus selection and (post-hoc) stimulus validation.

RESUMO

Introduction@#In the realm of education and professional licensure, the assessment of individuals’ competencies is pivotal in determining eligibility for entry into various fields of practice. Medical school assessments encompass cognitive and non-cognitive measures. The Philippines’ Physician Licensure Examination (PLE) relies solely on cognitive assessment. This study explored the predictive power of cognitive assessment in the passing the Physician Licensure Examinations.@*Methods@#A case-control study design was done. Cognitive examination grade was defined as the average cumulative grade of written examinations in specific subjects, while the dependent variable was PLE scores.@*Results@#The study revealed a positive association between failing written examinations and failing the Physician Licensure Examination. In all subjects, there is an observed association, but only Pharmacology reached statistical significance (OR: 2.30 CI:1.01,5.24). For the remaining subjects, although there is an association, it did not reach statistical significance (Biochemistry OR:1.42, CI: 0.43, 4.72; Medicine 3 OR:1.56, CI: 0.81, 3.0; Surgery 3 OR:1.28 CI: 0.63, 2.58). There was no association seen between failing the written examination and failing the PLE in Obstetrics (OR:0.98 CI: 0.47, 2.03). Furthermore, there was a weak positive correlation (0.18-0.31) between written examination grades and corresponding board exam subject grades for all subjects, highlighting the importance of cognitive assessments in predicting success. The research also found a statistically significant difference in PLE grades between those who failed the written examinations and those who passed.@*Conclusion@#These findings emphasized the crucial role of cognitive assessments in predicting success in the PLE and its associated board subjects. The study underscored the need for medical institutions to focus on strengthening cognitive competencies and to align the content and rigor of written examinations with the PLE. Addressing these issues would better prepare students for the licensure examination and enhance the quality of healthcare professionals entering the workforce. The results may contribute to the ongoing discussion on the effectiveness of assessment methods in medical education and licensure examinations.

RESUMO

@#Although melanoma only accounts for 1% of skin cancers, it is responsible for most skin cancer deaths. Glioblastoma multiforme, a high-grade astrocytoma, is the most aggressive and devastating primary brain tumor. These two diseases remain to be the biggest therapeutic challenge in both specialties of dermatology and neuro-oncology. A 53-year-old Filipino male who presented with a 2-year history of generalized dark brown and black patches on the body developed weakness and numbness of the left extremities. Biopsy and immunohistochemical staining of the skin revealed nodular melanoma with adjacent regressing melanoma. Biopsy of the intracranial mass showed glioblastoma multiforme. One month after the partial excision of the intracranial mass, the patient expired due to brain herniation. Nodular melanoma and glioblastoma multiforme may occur concomitantly in a patient. A review of the literature suggests a shared genetic predisposition. Its existence carries a poor prognosis and requires early detection to start aggressive treatment.

RESUMO

The Implicit Association Test (IAT) is commonly used for the indirect assessment of psychological constructs. While the features of the IAT that might influence the performance of the respondents have been extensively investigated, the effect of informing the respondents about the correctness of their responses (i.e., feedback presentation) has been poorly addressed so far. The study addresses this issue by presenting an across-domain (implicit prejudice and food preference) Rasch-based analysis of IAT data obtained with and without feedback presentation. Results showed that speed was influenced by the interaction between feedback presentation and associative condition, whereas accuracy was influenced by the associative condition. This result varied across-domain. Results suggested that IATs administered with feedback presentation provide more accurate information on the construct of interest.

RESUMO

Student protagonism is paramount in the knowledge construction process. In this paper, we discuss a didactic-pedagogical resource called licentîa hypomnema (LH), inspired in portfolios and learning diaries in which student-teachers record their understandings and reflections regarding pedagogical topics learned at University in a meta-learning process on learning about teaching. The initial context of the research was a Psychological Development and Teaching course, offered in the Teacher Education program at Universidade de Brasília (UnB). Two of the authors, then Literacy and Languages Teaching students, produced their LH and peer assessed each other during the course. In their annotations, the student-authors recorded two pedagogical situations related to the use of LH in their own teaching practices, causing an impact on their formative path. These materials consist of the data for analysis and discussion. Moreover, we discuss possible uses of reflexive writing in teacher education and other learning contexts. Producing a LH supports knowledge production and allows students to connect theory and practice, which consequently influences the student's teaching practice. Since LH is a didactic-pedagogical resource and not a close-ended tool, both the context and individuals who use it should be considered.(AU)


O protagonismo de estudantes tem grande importância no processo de construção do conhecimento. Neste artigo, discutimos um recurso didático-pedagógico chamado licentîa hypomnema (LH), inspirado em portfólios e diários de aprendizagem, isto é, estudantes de licenciatura escrevem suas compreensões e reflexões acerca de assuntos pedagógicos vistos na universidade em um processo de meta-aprendizagem sobre aprender a ensinar. O contexto inicial da pesquisa foi um curso de Desenvolvimento Psicológico e Ensino, ministrado em cursos de Licenciatura da Universidade de Brasília (UnB). Duas das autoras eram estudantes do curso de Letras, elas produziram seus LH, realizando avaliação por pares entre si durante o curso. As estudantes-autoras trouxeram em seus registros duas situações pedagógicas relacionadas ao uso desse recurso em suas próprias práticas de ensino que causaram um impacto em suas trajetórias formativas. São esses relatos que compõem os dados para análise e discussão. Além disso, procuramos discutir possíveis desdobramentos para o uso do recurso da escrita reflexiva na formação docente e em outros contextos de aprendizagem. A produção do LH fornece suporte para a produção de conhecimento e permite ao aluno conectar teoria e prática, o que, consequentemente, reverbera na prática de ensino do aluno. O LH é um recurso didático-pedagógico e não uma ferramenta fechada, portanto, tanto o contexto quanto as pessoas que o utilizam devem ser considerados.(AU)


El protagonismo de los estudiantes tiene gran importancia en el proceso de construcción del conocimiento. En este trabajo, discutimos un recurso didáctico-pedagógico llamado licentîa hypomnema (LH), que se inspira en diarios de aprendizaje, es decir, estudiantes de profesorado escriben sus comprensiones y reflexiones sobre temas pedagógicos aprendidos en la universidad, produciendo un proceso de meta-aprendizaje sobre aprender a enseñar. El contexto inicial de la investigación fue un curso de Desarrollo Psicológico y Enseñanza, impartido en el programa de Formación de Profesores de la Universidade de Brasília (UnB). Dos de las autoras eran alumnas de la carrera de Letras que produjeron sus LH y realizaron una evaluación por pares mutua durante el curso. Las estudiantes autoras plantearon en su LH dos situaciones pedagógicas relacionadas con el uso de este recurso en sus propias prácticas de enseñanza, causando un impacto en su trayectoria formativa. Estos materiales constituyen los datos para el análisis y la discusión en esta investigación. Buscamos discutir posibles desdoblamientos para el uso del recurso de la escritura reflexiva en la formación docente y en otros contextos de aprendizaje. La producción de este recurso da soporte a la producción de conocimiento y permite al estudiante conectar teoría y práctica, lo que consecuentemente repercute en su práctica docente. El LH es un recurso didáctico-pedagógico y no una herramienta cerrada, por lo tanto, se debe considerar tanto el contexto como las personas que lo utilizan.(AU)
