Investigation of Psychometric Properties of the Test for Creative Thinking—Drawing Production: Evidence from Study in Latvia

The Test for Creative Thinking—Drawing Production (TCT‐DP) is designed as an effective drawing‐based instrument for measuring creative potential. Many studies report adaptation efforts in other cultures pointing out good psychometric properties of the instrument nonetheless revealing also some trouble spots. The present study includes adaptation of TCT‐DP in Latvia and investigation of psychometric properties of the instrument such as measurement invariance between forms, sequence effect, gender differences, and factor structure of criteria employing methodology of structural equation modeling. Two samples were involved in the study—9th‐grade students (n = 300) and 15‐year‐old 9th‐grade students (n = 200). Results indicate that trained judges are able to achieve high reliability in evaluation of TCT‐DP total score and all criteria if some criteria are divided into subcategories. It was also found that TCT‐DP has measurement invariance between both forms but has small effect sizes regarding gender differences and method sequence. Observed differences of TCT‐DP total scores between the Latvian sample and relevant samples from Germany and Hong Kong could be considered as trivial. The study also revealed that, following original instructions, some test criteria had strong interdependence and therefore strategies in the evaluation process reducing interdependencies between criteria should be considered in future studies on the structure of TCT‐DP.     

How Alluring Are Dark Personalities? The Dark Triad and Attractiveness in Speed Dating

Dark Triad traits (narcissism, psychopathy, and Machiavellianism) are linked to the pursuit of short‐term mating strategies, but they may have differential effects on actual mating success in naturalistic scenarios: Narcissism may be a facilitator for men's short‐term mating success, while Machiavellianism and psychopathy may be detrimental. To date, little is known about the attractiveness of Dark Triad traits in women. In a speed‐dating study, we assessed participants' Dark Triad traits, Big Five personality traits, and physical attractiveness in N = 90 heterosexual individuals (46 women and 44 men). Each participant rated each partner's mate appeal for short‐ and long‐term relationships. Across both sexes, narcissism was positively associated with mate appeal for short‐ and long‐term relationships. Further analyses indicated that these associations were due to the shared variance among narcissism and extraversion in men and narcissism and physical attractiveness in women, respectively. In women, psychopathy was also positively associated with mate appeal for short‐term relationships. Regarding mating preferences, narcissism was found to involve greater choosiness in the rating of others' mate appeal (but not actual choices) in men, while psychopathy was associated with greater openness towards short‐term relationships in women.

Explaining Social Disparities in Mathematical Achievement: The Role of Motivation

This study examined the role of motivation as a mediator of the relationship between parents' socio‐economic status (SES) and children's standardized test achievement in math. We employed a one‐year longitudinal approach using Programme for International Student Assessment (PISA) 2003 and a follow‐up exam in 2004. The sample consisted of N = 6020 German students (mean age 15.5 years, SD = .55) who continued school after Grade 9 (PISA 2003) and were in Grade 10 at the time of PISA 2004. Children completed measures related to their parents' SES, math‐specific self‐concept, task‐specific and global self‐efficacy, and interest, intelligence and mathematical competence. We found a small to moderate correlation between parents' SES and children's achievement. All motivational constructs partially mediated the relationship between father's SES as well as a family index for SES (economic, social, and cultural status) and children's mathematical competence, but only math‐specific self‐concept and self‐efficacy were significant mediators for mother's SES. Even when simultaneously considering the mediating effect of children's intelligence and prior achievement, the mediation effects of motivation remained significant. These results are important for our understanding of educational equality. Copyright © 2016 European Association of Personality Psychology     

Ethnic Speech and Ethnic Action as Ethnic Behavior: Part 2. Validation of the Brunel Ethnic Behavior Inventory

This study sought to validate the Brunel Ethnic Behavior Inventory (BEBI) as a measure of two aspects of “doing” (i.e., ethnic speech and ethnic action) among the “ways of ethnicity” identified by Verkuyten. It also evaluates the construct validity of the BEBI alongside the Multigroup Ethnic Identity Measure-Revised (MEIM-R) and evaluates the BEBI and the MEIM-R (the latter of which measures exploration as “thinking” and commitment as “feeling” among ways of ethnicity) regarding criterion-related validity. Across two samples (n = 120 for Sample 1 and n = 148 for Sample 2), the BEBI and the MEIM-R performed suitably with regard to construct validity. However, the BEBI arguably performed better with regard to criterion-related validity (i.e., in predicting scores on life satisfaction, flourishing, positive and negative moods, and positive and negative emotions). Implications for validation studies on ways of ethnicity are discussed.     

The effect of layout and pacing on learning from diagrams with unnecessary text

Although the presentation of extraneous (i.e., irrelevant or unnecessary) information hinders learning, it is unclear whether and how layout and pacing influence this effect. In two experiments, participants learned how the heart functions using four different layouts: a diagram presented without unnecessary text (diagram only), with unnecessary text separated from the diagram (separated) or integrated into the diagram (integrated), or with separated unnecessary text and the instruction to integrate (integration instruction). In Experiment 1, study time was self‐paced for half of the participants and system paced for the other half. There were no effects of layout and of pacing on learning, although system pacing was more effortful than self‐pacing. In Experiment 2, which was system paced and employed eye tracking, the integrated condition showed worse learning outcomes than the separated condition. Moreover, in the integrated condition, participants made more integration attempts between the unnecessary text and the diagram than in the separated condition.     

Predicting stuttering from phonetic complexity in German

This study investigated how phonetic complexity affects stuttering rate in German and how this changes developmentally. Phonetic difficulty was assessed using Jakielski's index [Motor Organization in the Acquisition of Consonant Clusters, Dissertation/Ph.D. Thesis, University of Texas Austin, 1998] of phonetic complexity (IPC) in which words are scored on eight different characteristics. Stuttering rate was not related to IPC score for German function words, as previously shown for Spanish and English. Significant correlations between stuttering rate and IPC score were found for content words for children over the age of six and adults. It was also found that German content words have a higher mean IPC sum compared to their English counterparts. There was a bigger difference in IPC score between fluent and stuttered words in German than in English. Factor 5 (word shape) influenced stuttering rates in both German age groups. This has also been found for Spanish but does not apply to English. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) describe a method to measure phonetic complexity and how this affects stuttering rates for words of different grammatical classes; (2) explain why this method is suitable for different languages and age groups; (3) detect which phonetic characteristics have most impact on different age groups in English and German; (4) assess possible theoretical reasons for these findings.     

Active hippocampus during nonconscious memories

The hippocampal formation is known for its importance in conscious, declarative memory. Here, we report neuroimaging evidence in humans for an additional role of the hippocampal formation in nonconscious memory. We maskedly presented combinations of faces and written professions such that subjects were not aware of them. Nevertheless, the masked presentations activated many of the brain regions that unmasked presentations of these stimuli did. To induce a nonconscious retrieval of the faces and face-associated occupational information, subjects were instructed to view the previously masked faces and to guess the professional category of each person--academic, artist, and workman. Guessing the professional category of previously masked versus new faces activated the left and right hippocampal formation and right perirhinal cortex as well as bilateral fusiform areas and fronto-temporal areas known to mediate the retrieval of semantic information. These activations within the semantic processing system suggest that conceptual knowledge acquired during masking was nonconsciously retrieved. Our data provide clues to an analogous role of the hippocampus in conscious and nonconscious memory.     

Predicting post-event processing in social anxiety disorder following two prototypical social situations: State variables and dispositional determinants

This study investigated self-reported state (anxiety, physical symptoms, cognitions, internally focused attention, safety behaviors, social performance) and trait (social anxiety, depressive symptoms, dysfunctional self-consciousness) predictors of post-event processing (PEP) subsequent to two social situations (interaction, speech) in participants with a primary diagnosis of social anxiety disorder (SAD) and healthy controls (HC). The speech triggered significantly more intense PEP, especially in SAD. Regardless of the type of social situation, PEP was best predicted by situational anxiety and dysfunctional cognitions among the state variables. If only trait variables were considered, PEP following both situations was accounted for by trait social anxiety. In addition, dysfunctional self-consciousness contributed to PEP-speech. If state and trait variables were jointly considered, for both situations, situational anxiety and dysfunctional cognitions were confirmed as the most powerful PEP predictors above and beyond trait social anxiety (interaction) and dysfunctional self-consciousness (speech). Hence, PEP as assessed on the day after a social situation seems to be mainly determined by state variables. Trait social anxiety and dysfunctional self-consciousness also significantly contribute to PEP depending on the type of social situation. The present findings support dysfunctional cognitions as a core cognitive mechanism for the maintenance of SAD. Implications for treatment are discussed.
