The Croatian version of the Emotion Regulation Questionnaire: Links with higher- and lower-level personality traits and mood

The Emotion Regulation Questionnaire (ERQ) measures habitual use of two emotion regulation strategies, cognitive reappraisal and expressive suppression. The present study tested the psychometric properties and validity of a newly developed Croatian adaptation of the ERQ. In a sample of 347 participants, we first sought to confirm the ERQ's original factor structure. Next, we tested its convergent, divergent and incremental validity. In the first subsample (N = 140), we linked the ERQ with a measure of the Five-Factor Model dimensions and their facets (Revised NEO Personality Inventory). In the second subsample (N = 207), we tested its ability to predict personality dimensions assessed by a different measure (Big Five Inventory) as well as the traits of positive and negative affect, including its incremental validity in predicting the latter. The results corroborated earlier findings, showing that the Croatian ERQ has equivalent psychometrics and predictive validity as ERQs in other languages. Crucially, the observed links between the ERQ and the facets of the Five-Factor Model dimensions enrich our understanding of the personality mechanisms behind the employment of these emotion regulation strategies.     

Boys Just Don’t! Gender Stereotyping and Sanctioning of Counter-Stereotypical Behavior in Preschoolers

Sex Roles - Although children start to adopt gender stereotypes by the age of three, there is less evidence about how early they start to sanction other children’s counter-stereotypical...     

Effect of social organisation on interspecific differences in overmarking behaviour of foals in African equids

Animal Cognition - Overmarking remains an unstudied topic in juvenile mammals. We have previously documented a very high rate of overmarking by foals in four captive African equid species: mountain...

Impaired verb fluency: a sign of mild cognitive impairment

We assessed verb fluency vs. noun and letter-based fluency in 199 subjects referred for cognitive complaints including Subjective Cognitive Impairment, Mild Cognitive Impairment, and Alzheimer's disease. ANCOVAs and factor analyses identified verb, noun, and letter-based fluency as distinct tasks. Verb fluency performance in Mild Cognitive Impairment differed significantly from Subjective Cognitive Impairment and Alzheimer's disease. Reduced verb fluency thus appears to be a linguistic marker for incipient dementia. One possibility is that the verb fluency deficit in Mild Cognitive Impairment results from degenerative processes known to occur in the parahippocampal region.     

Geometric and perceptual effects of the location of the observer vantage point for linear-perspective images

New geometric analyses are presented of three impressive examples of the effects of location of the vantage point on virtual 3-D spaces conveyed by linear-perspective images. In the 'egocentric-road' effect, the perceived direction of the depicted road is always pointed towards the observer, for any position of the vantage point. It is shown that perspective images of real-observer-aimed roads are characterised by a specific, simple pattern of projected side lines. Given that pattern, the position of the observer, and certain assumptions and perspective arguments, the perceived direction of the virtual road towards the observer can be predicted. In the 'skewed balcony' and the 'collapsing ceiling' effects, the position of the vantage point affects the impression of alignment of the virtual architecture conveyed by large-scale illusionistic paintings and the real architecture surrounding them. It is shown that the dislocation of the vantage point away from the viewing position prescribed by the perspective construction induces a mismatch between the painted vanishing point of elements in the picture and the real vanishing point of corresponding elements of the actual architecture. This mismatch of vanishing points provides visual information that the elements of the two architectures are not mutually parallel.     

The relationship between active hand and ear advantage in the native and foreign language

In an experimental design involving two auditorily presented competing commands (one to each ear), 144 right-handed subjects (72 male and 72 female) were asked to provide motor responses. Half of each group of subjects was responding with their right hand and the other half with the left. The test was applied in the subjects' native language (Croatian) and in English, which they had learned as a foreign language. Ear advantage was determined by calculating laterality indices from the order of responding to the commands. On average, right-ear advantage was found in all conditions. Analysis of results revealed the effect of the active hand in Croatian (with significant decrease in the right-ear advantage when using the left hand). The same trend failed to reach significance in English. In responses to English stimuli, there was a significant effect of gender (with men exhibiting a lower right-ear advantage than women). The same trend was not significant for Croatian stimuli. The consistently lower right-ear advantage found in male subjects is contrary to the traditional assumptions that men are more lateralized than women and warrants further investigation.     

Perceptions of body image among Japanese and Croatian children of preschool age

This study examined the differences in current and ideal body size among 108 Japanese and 129 Croatian preschool children (M=4.9 yr.). Boys and girls in both samples showed similarities by selecting the figure representing their current body size. Significant sex differences were found in selection of an ideal figure in the Japanese sample but not in the Croatian group. Japanese girls showed greater preference for a thinner figure than boys. In selection of an ideal body size significant cultural differences were found only for boys: Japanese boys preferred thinner figures. Results relating to body discrepancy (Current minus Ideal figures) indicated that there were fewer satisfied Japanese girls than Croatian girls whereas for the boys, a significantly larger number of Japanese than Croatian boys wished to be heavier.     

Stress applied during primary immunization affects the secondary humoral immune response in the rat: involvement of opioid peptides

The effect of unpredictable, inescapable and uncontrollable electric tail shocks (ES) on the humoral immune response to bovine serum albumin (BSA) was investigated in the rat. Contributions of the procedures that accompany shock delivery, such as witnessing the ES procedure (stress witnessing, SW) and exposure to the apparatus for shock delivery (apparatus control, AC) to the changes in specific immunity induced by ES were also tested. All procedures were applied during primary and/or secondary immunization. It was demonstrated that exposure to ES during primary immunization with BSA significantly suppressed specific anti-BSA antibody production after secondary and tertiary immunization with the same antigen. Exposure to the SW procedure during primary immunization with BSA enhanced the specific antibody level after secondary immunization, while exposure to the apparatus alone did not influence the development of either the primary or secondary humoral immune response to BSA. Both ES-induced suppression and SW-induced potentiation of the humoral immune response were partially inhibited by prior treatment with the opioid receptor antagonist naloxone. Additionally, treatments with the opioid peptides methionine- and leucine-enkephalin decreased anti-BSA antibody level, mimicking to some extent the effects of ES. It is suggested that ES and endogenous opioid peptides had long-term effects on humoral immunity through mechanisms involving immunologic memory.     

Age differences in personality across the adult life span: parallels in five cultures

Both cross-sectional and longitudinal studies in the United States have shown consistent changes between college age and middle adulthood. There appear to be declines in 3 of the 5 major factors of personality--Neuroticism, Extraversion, and Openness--and increases in Agreeableness and Conscientiousness. To examine cross-cultural generalizability of these findings, translations of the Revised NEO Personality Inventory were administered to samples in Germany, Italy, Portugal, Croatia, and South Korea (N = 7,363). Similar patterns of age differences were seen in each country, for both men and women. Common trends were also seen for the more specific traits that define the major factors. Because these nations differ substantially in culture and recent history, results suggest the hypothesis that these are universal maturational changes in adult personality.
