Analysis of English free association network reveals mechanisms of efficient solution of Remote Association Tests.

We study correlations between the structure and properties of a free association network of the English language, and solutions of psycholinguistic Remote Association Tests (RATs). We show that average hardness of individual RATs is largely determined by relative positions of test words (stimuli and response) on the free association network. We argue that the solution of RATs can be interpreted as a first passage search problem on a network whose vertices are words and links are associations between words. We propose different heuristic search algorithms and demonstrate that in "easily-solving" RATs (those that are solved in 15 seconds by more than 64% subjects) the solution is governed by "strong" network links (i.e. strong associations) directly connecting stimuli and response, and thus the efficient strategy consist in activating such strong links. In turn, the most efficient mechanism of solving medium and hard RATs consists of preferentially following sequence of "moderately weak" associations.

Profiling Speech Sound Disorders for Clinical Validation of the Computer Articulation Instrument.

Purpose The current article presents data from 2 studies on clinical groups of children referred for speech assessment. The aims of these studies are to validate the Computer Articulation Instrument (CAI) with the known-group validation method and to determine the differential diagnostic power of the resulting speech profiles. Method Study 1 examined known-group validity by comparing the scores of 93 children diagnosed with speech-language difficulties on the picture naming (PN) task of the CAI with intelligibility judgments given by speech-language pathologists. In Study 2, the speech profiles of 41 children diagnosed with speech sound disorders (SSDs), consisting of 4-6 factor scores extracted from the 4 tasks of the CAI, namely, PN, nonword imitation (NWI), word and nonword repetition, and maximum repetition rate (MRR), were validated against clinical judgments of severity of the SSD given by speech-language pathologists. Results In Study 1, a repeated-measures analysis of variance revealed a significant effect of intelligibility level on the PN performance of the CAI and there were highly significant correlations between intelligibility and PN performance in the expected direction. Neither intelligibility level nor PN performance was related to nonverbal intelligence and language scores. The analysis of variance and a series of t tests in Study 2 revealed significant differences between the moderate and severe groups for the CAI factors based on PN and NWI and the bisyllabic and trisyllabic sequences of MRR, but not for the factor word and nonword proportion of whole-word variability based on word and nonword repetition, and the monosyllabic sequences of MRR. These results suggest that, especially, the tasks PN, NWI, and the bisyllabic and trisyllabic sequences of MRR are most sensitive for diagnosing SSDs. Conclusions The findings of these 2 studies support the known-group validity of the CAI. Together with the results of a previous study of our group on reliability and validity ( van Haaften et al., 2019 ), we can conclude that the CAI is a reliable and valid tool for assessment of children with SSDs.

A systematic review of the word sentence association paradigm (WSAP).

BACKGROUND AND OBJECTIVES: The Word Sentence Association Paradigm (WSAP) was originally designed to assess and modify interpretive biases (IB) in socially anxious individuals. Researchers have since modified the WSAP for use across various populations. Despite its widespread use, no studies have systematically reviewed the WSAP to determine its validity and reliability. METHODS: We review variations to the WSAP, populations in which the WSAP has been used, reliability data, and effect sizes across 41 studies published between 2008 and March 2018. RESULTS: Results indicate that the WSAP has been utilized to target 18 disorders and symptoms in adults and children. Modifications include stimulus content, timing parameters, and presentation order of word and sentence pairs. Reported internal consistency and test-retest reliability suggest good to excellent reliability. Medium to large effect sizes were reported when comparing control samples to those with psychopathology and in pre-post comparisons of the modification version of the WSAP. LIMITATIONS: Studies varied regarding which indices of the WSAP were presented and specific task parameters used, making it challenging to compare effects. CONCLUSIONS: The WSAP is a reliable and valid instrument for assessing and modifying interpretive biases with unique characteristics compared with other IB assessment and modification tasks.

The added value of implicit motives for management research Development and first validation of a Brief Implicit Association Test (BIAT) for the measurement of implicit motives.

Many Management (sub-)disciplines, from Organizational Behavior and Marketing to Accounting and Strategy, are interested in antecedents and consequences of individual attitudes and traits. A key aspect of personality profiles are explicit and implicit motives. Yet, Management scholars mainly focus on explicit motives, with limited attention to implicit motives. We argue that this state of affairs probably came into being because current Management researchers mainly rely on implicit motive measures that are either difficult to apply or to develop, hampering researchers from applying implicit motive measures. To overcome the downsides of available instruments, we develop a Brief Implicit Association Test (BIAT) as an efficient, reliable and valid measure of implicit motives, particularly the needs for achievement, affiliation and power. To explore our BIAT's predictive validity, we apply this measure to a specific research domain within Management: Entrepreneurship. We examine implicit motives' association with entrepreneurial self-efficacy, business founding, and financial profitability. Our results show that the introduction of implicit motives can unlock stranded discussions in this research domain. Overall, we argue that implicit motives can help to push the boundaries of the study of deep-level attributes in a wide range of organizational and managerial settings.

Color associations to emotion and emotion-laden words: A collection of norms for stimulus construction and selection.

Color has the ability to influence a variety of human behaviors, such as object recognition, the identification of facial expressions, and the ability to categorize stimuli as positive or negative. Researchers have started to examine the relationship between emotional words and colors, and the findings have revealed that brightness is often associated with positive emotional words and darkness with negative emotional words (e.g., Meier, Robinson, & Clore, Psychological Science, 15, 82-87, 2004). In addition, words such as anger and failure seem to be inherently associated with the color red (e.g., Kuhbandner & Pekrun). The purpose of the present study was to construct norms for positive and negative emotion and emotion-laden words and their color associations. Participants were asked to provide the first color that came to mind for a set of 160 emotional items. The results revealed that the color RED was most commonly associated with negative emotion and emotion-laden words, whereas YELLOW and WHITE were associated with positive emotion and emotion-laden words, respectively. The present work provides researchers with a large database to aid in stimulus construction and selection.

Toward a meaningful metric of implicit prejudice.

[Correction Notice: An Erratum for this article was reported in Vol 100(5) of Journal of Applied Psychology (see record 2015-40760-001). there are errors in some of the values listed in Table 6 that do not alter any of the conclusions or substantive statements in the original article. The corrected portion of Table 6 is in the correction. The positive intercepts in this table represent the estimated IAT score when the criterion has a value of zero (suggesting attitudinal neutrality), except in the equation examining voter preference in Greenwald et al. (2009), where the intercept estimated the IAT score of Obama voters.] The modal distribution of the Implicit Association Test (IAT) is commonly interpreted as showing high levels of implicit prejudice among Americans. These interpretations have fueled calls for changes in organizational and legal practices, but such applications are problematic because the IAT is scored on an arbitrary psychological metric. The present research was designed to make the IAT metric less arbitrary by determining the scores on IAT measures that are associated with observable racial or ethnic bias. By reexamining data from published studies, we found evidence that the IAT metric is "right biased," such that individuals who are behaviorally neutral tend to have positive IAT scores. Current scoring conventions fail to take into account these dynamics and can lead to faulty inferences about the prevalence of implicit prejudice.

Cognitive intervention in semantic dementia: maintaining words over time.

Patients with semantic dementia (SD) can improve their naming ability through cognitive intervention, with good retention 1 month later. Beyond this time, improvements often fade, yet no studies have investigated how to maintain performance. Nine SD patients completed a 2-month word training program and were then monitored over 6 months: firstly for 2 months without training, followed by a further 4 months, where additional training was provided to revise words, if required. All patients improved their naming immediately postintervention (P<0.001). After 2 months without practice, significant declines occurred in 4 patients. To sustain at least 80% of their postintervention performance 6 months later, 4 patients required minimal revision (<10 sessions over the period), 2 required regular weekly or biweekly revision sessions, with the remaining 3 patients requiring no revision sessions. During this period, group results indicated some decline in words that were initially known, but were not trained. Improvements in naming can be sustained in SD patients, with the support of less intense, but ongoing revision. Training words that are still known appears to help prolong memory of these words.

Word association norms in Mexican Spanish

The aim of this research is to present a Spanish Word Association Norms (WAN) database of concrete nouns. The database includes 234 stimulus words (SWs) and 67,622 response words (RWs) provided by 478 young Mexican adults. Eight different measures were calculated to quantitatively analyze word-word relationships: 1) Associative strength of the first associate, 2) Associative strength of the second associate, 3) Sum of associative strength of first two associates, 4) Difference in associative strength between first two associates, 5) Number of different associates, 6) Blank responses, 7) Idiosyncratic responses, and 8) Cue validity of the first associate. The resulting database is an important contribution given that there are no published word association norms for Mexican Spanish. The results of this study are an important resource for future research regarding lexical networks, priming effects, semantic memory, among others (AU)

ANGST: affective norms for German sentiment terms, derived from the affective norms for English words.

We present the German adaptation of the Affective Norms for English Words (ANEW; Bradley & Lang in Technical Report No. C-1. Gainsville: University of Florida, Center for Research in Psychophysiology). A total of 1,003 Words-German translations of the ANEW material-were rated on a total of six dimensions: The classic ratings of valence, arousal, and dominance (as in the ANEW corpus) were extended with additional arousal ratings using a slightly different scale (see BAWL: Võ et al. in Behavior Research Methods 41: 531-538, 2009; Võ, Jacobs, & Conrad in Behavior Research Methods 38: 606-609, 2006), along with ratings of imageability and potency. Measures of several objective psycholinguistic variables (different types of word frequency counts, grammatical class, number of letters, number of syllables, and number of orthographic neighbors) for the words were also added, so as to further facilitate the use of this new database in psycholinguistic research. These norms can be downloaded as supplemental materials with this article.

Predicting ethnic and racial discrimination: a meta-analysis of IAT criterion studies.

This article reports a meta-analysis of studies examining the predictive validity of the Implicit Association Test (IAT) and explicit measures of bias for a wide range of criterion measures of discrimination. The meta-analysis estimates the heterogeneity of effects within and across 2 domains of intergroup bias (interracial and interethnic), 6 criterion categories (interpersonal behavior, person perception, policy preference, microbehavior, response time, and brain activity), 2 versions of the IAT (stereotype and attitude IATs), 3 strategies for measuring explicit bias (feeling thermometers, multi-item explicit measures such as the Modern Racism Scale, and ad hoc measures of intergroup attitudes and stereotypes), and 4 criterion-scoring methods (computed majority-minority difference scores, relative majority-minority ratings, minority-only ratings, and majority-only ratings). IATs were poor predictors of every criterion category other than brain activity, and the IATs performed no better than simple explicit measures. These results have important implications for the construct validity of IATs, for competing theories of prejudice and attitude-behavior relations, and for measuring and modeling prejudice and discrimination.

Psychometric properties of the internet addiction test in Chinese adolescents.

OBJECTIVE: This study examined the psychometric properties of the Young's Internet Addiction Test (IAT) in 844 Hong Kong Chinese adolescents (37.7% boys) with mean age of 15.9 (standard deviation = 3.5) years. METHODS: Demographic items, Internet use habits, IAT, and the Revised Chen Internet Addiction Scale (CIAS-R) were administered. 3 percent of the participants were classified as addicted and 31.6% as occasional problematic Internet users. Confirmatory factor analysis results indicated that the 18-item second-order three-factor model has the best fit with our data (Satorra-Bentler scaled χ(2) = 160.56, df = 132, p < .05, normed fit index = 0.95, non-normed fit index = 0.99, comparative fit index = 0.99, root mean square error of approximation = 0.02). RESULTS: IAT demonstrated strong internal consistency (Cronbach's α = .93). Satisfactory concurrent and convergent validity of IAT were found moderately correlated with CIAS-R (r = .46) and the average online time per day (r = .40 for weekdays; r = .37 for weekends). CONCLUSION: IAT has evidence of being a valid and reliable scale for screening Internet addiction in Chinese adolescents.

Norms of valence, arousal, and dominance for 13,915 English lemmas.

Information about the affective meanings of words is used by researchers working on emotions and moods, word recognition and memory, and text-based sentiment analysis. Three components of emotions are traditionally distinguished: valence (the pleasantness of a stimulus), arousal (the intensity of emotion provoked by a stimulus), and dominance (the degree of control exerted by a stimulus). Thus far, nearly all research has been based on the ANEW norms collected by Bradley and Lang (1999) for 1,034 words. We extended that database to nearly 14,000 English lemmas, providing researchers with a much richer source of information, including gender, age, and educational differences in emotion norms. As an example of the new possibilities, we included stimuli from nearly all of the category norms (e.g., types of diseases, occupations, and taboo words) collected by Van Overschelde, Rawson, and Dunlosky (Journal of Memory and Language 50:289-335, 2004), making it possible to include affect in studies of semantic memory.

Estimating the contributions of associations and recoding in the Implicit Association Test: the ReAL model for the IAT.

We introduce the ReAL model for the Implicit Association Test (IAT), a multinomial processing tree model that allows one to mathematically separate the contributions of attitude-based evaluative associations and recoding processes in a specific IAT. The ReAL model explains the observed pattern of erroneous and correct responses in the IAT via 3 underlying processes: recoding of target and attribute categories into a binary representation in the compatible block (Re), evaluative associations of the target categories (A), and label-based identification of the response that is assigned to the respective nominal category (L). In 7 validation studies, using an adaptive response deadline procedure in order to increase the amount of erroneous responses in the IAT, we demonstrated that the ReAL model fits IAT data and that the model parameters vary independently in response to corresponding experimental manipulations. Further studies yielded evidence for the specific predictive validity of the model parameters in the domain of consumer behavior. The ReAL model allows one to disentangle different sources of IAT effects where global effect measures based on response times lead to equivocal interpretations. Possible applications and implications for future IAT research are discussed.

Symptom validity indicators embedded in the Controlled Oral Word Association Test.

Embedded symptom validity measures facilitate the detection of below-capacity performance in neuropsychological assessment. A number of such indicators have been proposed for the Controlled Oral Word Association Test (COWAT), a widely used test of word generation. However, several of these embedded indicators have not been cross-validated and it is currently unclear which represent the optimal combination of predictors. This study used Bayesian Model Averaging (BMA) to determine the set of predictors that best differentiate between patients presenting with (n = 46) and without (n = 55) malingered neurocognitive dysfunction (MND). Mild traumatic brain injury was the most common diagnosis in the MND group (96%). BMA selected the COWAT total score and a measure of change in output over time. A logistic regression model combining these variables yielded good discriminability, with an AUC of. 774, (95% confidence interval = .679 to. 869), 78% of cases were classified correctly, with 67% sensitivity and 88% specificity. Two alternative models performed similarly, but the variables involved required slightly longer administration and/or calculation time, making them somewhat less desirable. These results support the use of a weighted combination of embedded symptom validity measures in the COWAT.

Language development, interpersonal communication, and academic achievement among Japanese children as assessed by the ALADJIN.

OBJECTIVES: Japanese-speaking children in a standard sample were subjected to a test battery (ALADJIN: Assessment Package for Language Development in Japanese Hearing-Impaired Children) to evaluate the effect of language development on both interpersonal communication skills and academic achievement. METHODS: A total of 414 preschool and school-age children without hearing impairment were included in this study. The following tests make up the ALADJIN: the Test of Question-Answer Interaction Development (TQAID), the Japanese Language by Criterion Referenced Test-II (CRT-II) for measuring academic achievement, the Picture Vocabulary Test-Revised (PVT-R), the Standardized Comprehension Test of Abstract Words (SCTAW), both parts of the Syntactic Processing Test for Aphasia (STA), and the Word Fluency Test (WFT). Means and standard deviations at each academic grade level were calculated, and a multiple regression analysis was performed. RESULTS: A ceiling effect was observed for the TQAID and the STA in children in grade 3 of elementary school, and the scores for the PVT-R, SCTAW, and WFT increased incrementally according to grade level. Multiple regression analysis revealed that the PVT-R, WFT, and STA (production) have predictive power for the results of the TQAID (R = 0.59; R2 = 0.58; p <0.0001), whereas the SCTAW and STA (comprehension) have predictive power for the results of the CRT-II. CONCLUSIONS: Both vocabulary and syntax are important in communication development among children. The results of our multiple regression analysis suggest that different language domains may play different roles in the development of interpersonal communication skills and in academic achievement. The development of interpersonal communication skills is largely based on productive vocabulary and syntax abilities, whereas academic achievement is largely based on comprehensive vocabulary and syntax abilities. Children who have difficulties in either area should be evaluated with detailed language assessment tools such as the ALADJIN in an effort to aid in the selection of appropriate intervention.

Syntactic development in Japanese hearing-impaired children.

OBJECTIVES: This study examined syntactic development of auditory comprehension of sentences in Japanese-speaking school-age children with and without hearing impairment. METHODS: In total, 592 preschool and school-age children (421 normal-hearing and 171 hearing-impaired) were included in this cross-sectional observation study conducted using the Syntactic Processing Test for Aphasia for Japanese language users. Linear regression analysis was used to determine the estimated age at which each syntactic structure was acquired. RESULTS: Acquisition of syntactic structures was observed in hearing-impaired and normal-hearing children. Basic word order sentences of agent-object-verb and the goal benefactive construction were acquired at preschool age (earlier group), whereas reverse word order sentences of object-agent-verb, source benefactive construction, passive voice, and relative clauses were acquired at school age (later group). The results showed that many hearing-impaired children may not acquire Japanese grammatical structures until the age of 12 years. CONCLUSIONS: Adequate screening for language development for school-age hearing-impaired children is required for an effective intervention.

Falso reconocimiento en listas DRM con tres palabras críticas: Asociación directa vs. inversa / False recognition in DRM lists with three critical words: Forward vs. Backward association

En este trabajo se ha estudiado el falso reconocimiento utilizando el paradigma Deese/Roediger-McDermott (DRM). Concretamente, se ha analizado el efecto diferencial de la fuerza asociativa directa e inversa sobre el falso reconocimiento, a la vez que se ha estudiado el papel desempeñado por el alto o bajo nivel de asociación de las listas en este tipo de ilusiones asociativas de memoria. Se emplearon 16 listas compuestas por 6 palabras asociadas y 3 palabras críticas. Ocho listas se construyeron a partir de la fuerza asociativa directa y ocho a partir de la fuerza asociativa inversa. Se controlaron los niveles de asociación de las listas para que las listas fueran comparables entre sí en cuanto a nivel de asociación, existiendo dos grupos en función del alto o bajo nivel de asociación. Los resultados mostraron que las listas DRM con 3 palabras críticas producían falso reconocimiento, siendo adecuada su utilización en procedimientos experimentales que requieran emplear más de un ensayo crítico por lista. Al comparar los diferentes tipos de listas, los análisis indicaban que el porcentaje de falso reconocimiento de las listas con baja fuerza asociativa directa (19.50%) era significativamente más bajo que el falso reconocimiento del resto de las listas (alta y baja fuerza asociativa inversa y alta fuerza asociativa directa), donde el falso reconocimiento superaba el 42%(AU)

False recognition (FR) was studied in one experiment using the Deese/Roediger-McDermott (DRM) paradigm. Specifically, the differential contributions of forward associative strength and backward associative strength were analyzed, together with an analysis of the role played by the associative level of the lists on this kind of memory illusion. Materials consisted of 16 lists, each was formed by 6 to-beremembered associates and 3 critical, never studied, words. Eight lists were constructed on the basis of forward associative strength, and the other 8 lists were constructed on the basis of backward associative strength. In all cases, the lists were matched for level of association, and further divided into two sets, to obtain comparable lists of each type with high and low associative levels. The results showed that, globally, DRM lists with 3 critical words produced robust levels of false recognition, rendering them appropriate for experimental procedures that require more than one critical trial per list. A comparison of the different types of lists revealed that false recognition with low forward-associative-strength lists (19.50%) was significantly lower than with the other 3 types of lists (low and high backward-associative-strength, and high forward-associative-strength), for which false recognition exceeded 42%(AU)

Age acquisition norms from elderly Spanish people: characteristics and the prediction of word recognition performance in Alzheimer’s disease

La edad de adquisición es una de las variables más determinante del acceso léxico. También es la que mejor determina los procesos de pérdida de las palabras en los pacientes que han sufrido lesión cerebral, así como en la enfermedad de Alzheimer. Pero las escalas de edad de adquisición de que se dispone actualmente han sido todas construidas con jóvenes universitarios. Y obviamente las edades de adquisición para muchas palabras no son las mismas en los jóvenes actuales que en las personas mayores. El objetivo de este estudio fue elaborar normas de edad de adquisición para una muestra de 500 palabras con personas mayores de 60 años. Al comparar la capacidad de predicción de esta escala con otra elaborada con jóvenes de los resultados de un grupo pacientes de Alzheimer en una tarea de selección léxica se encontró que efectivamente esta escala predice mejor los datos. En consecuencia, en los estudios que se realicen con personas mayores debería de utilizar esta escala en vez de las obtenidas con jóvenes(AU)

Age of acquisition is possibly the single most potent variable affecting lexical access. It is also a variable that determines the retention or loss of words in patients who have suffered brain injury, and in patients with Alzheimer's disease. But the norms of age of acquisition currently available have largely been obtained from university students whereas the ages of acquisition for some words are very different for young people compared with the elderly. The aim of this study was to develop age of acquisition norms for a sample of 500 words with people over 60 years. When these norms were compared with others from young people in predicting the results of a group of Alzheimer patients in a lexical selection task we found that the elderly ratings made a better prediction of the data. We recommend that for studies using older participants appropriate norms should be used in place of those obtained from young adults(AU)
