Language comprehension vs. language production: age effects on fMRI activation

Normal language acquisition is a process that unfolds with amazing speed primarily in the first years of life. However, the refinement of linguistic proficiency is an ongoing process, extending well into childhood and adolescence. An increase in lateralization and a more focussed productive language network have been suggested to be the neural correlates of this process. However, the processes underlying the refinement of language comprehension are less clear. Using a language comprehension (Beep Stories) and a language production (Vowel Identification) task in fMRI, we studied language representation and lateralization in 36 children, adolescents, and young adults (age 6-24 years). For the language comprehension network, we found a more focal activation with age in the bilateral superior temporal gyri. No significant increase of lateralization with age could be observed, so the neural basis of language comprehension as assessed with the Beep Stories task seems to be established in a bilateral network by late childhood. For the productive network, however, we could confirm an increase with age both in focus and lateralization. Only in the language comprehension task did verbal IQ correlate with lateralization, with higher verbal IQ being associated with more right-hemispheric involvement. In some subjects (24%), language comprehension and language production were lateralized to opposite hemispheres.     

Impersonal Sex Orientation and Multitasking Influence the Effect of Sexual Media Content on Involvement With a Sexual Character

The aim of the present study was to investigate whether responses to sexual media content depend on personal and situational factors. Specifically, we studied the role of the personal factor impersonal sex orientation (IS) and the situational factor multitasking in the effect of sexual media content on involvement with the character, a concept that has received increasing attention as an explanation of sexual media effects. College-aged women who were low or high in IS watched a neutral scene or a sex scene. Half of the participants in the neutral and sex condition had to multitask (a tone detection task) while viewing the scene. In the sex condition, participants high in IS were more involved with the character than participants low in IS. Multitasking resulted in opposite patterns of involvement with the character in the sex condition: Participants high in IS became less involved with the character, whereas participants low in IS became more involved with the character.     

Identity configurations across love and work in emerging adults in romantic relationships

Love and work constitute two life-defining identity domains for emerging adults. The present study utilized a five-dimensional identity model and examined identity configurations across these two domains, capturing the degree to which identity statuses correspond across domains. A sample of German 18–30-year-olds who were either working or studying and engaged in a romantic relationship was assessed at baseline and three years later. Six identity clusters emerged in each domain. Combining identity clusters across love and work domains, 7 identity configurations were distinguished. Whereas some configurations were characterized by strong commitments in one or both domains, other configurations consisted of individuals scoring low on commitment and high on exploration and rumination. These configurations were differentially related to psychological symptoms, work stress and satisfaction, and family–work conflict, both concurrently and longitudinally. Individuals characterized by high commitments in love and work provided the most favorable responses on all outcomes.     

Reflective Personality: Identifying Cognitive Style and Cognitive Complexity

Categorized among learning practices, reflection involves cognitive processing. Some people say they reflect often, whereas others claim they are less inclined to reflect on a regular basis. The present study examines reflection in an academic learning setting. In contrast with previous studies testing reflective task accomplishment, we are interested in personality traits that can predict reflection or a reflective outcome. By means of a survey university students are questioned about their learning practices when working on their final thesis. To test whether certain traits influence reflection and whether reflection produces cognitive outcomes at the individual level, we performed hierarchical regression analysis. In addition, structural equation modeling is used to test for the mediation effects of reflection. The data stress a mediating role of reflection in the relationship between particular personality traits and cognitive complexity.     

Beyond the Individual: Promoting Mental and Behavioural Health in Low- and Middle-income Countries

This brief report describes a programmatic approach to health promotion that can help address the social determinants of mental-health and associated risky behaviours. Using a South African case example, we illustrate that while micro-system interventions help to strengthen individual resilience and immediate proximal protective influences, group system interventions can assist to promote health enhancing social identities and representations. We conclude that multi-level interventions that assume a systemic focus can strengthen community transformative efforts to address social determinants of mental and behavioural health.     

On Gender Specificity of Person Characteristics in Personnel Advertisements: A Study Among Future Applicants

This research is an examination of how person characteristics mentioned in personnel advertisements influence the judgments of male and female students with regard to their subjective eligibility for, and the attractiveness of, a particular vacancy. The first study showed that many frequently mentioned person characteristics in personnel advertisements applied differently to men and women, but that female characteristics were more in demand than male characteristics. The second study examined to what degree male and female participants felt that they themselves possessed male and female characteristics; results showed that the men were more confident about the degree to which they possessed male and female characteristics than the women were. The third study examined how the type of person characteristics mentioned in personnel advertisements influenced men's and women's judgments regarding their eligibility for and the attractiveness of a particular position. The men found all positions about equally attractive, whereas the women found “male” positions considerably less attractive. Implications of the study are discussed.     

Moving the eyes along the mental number line: comparing SNARC effects with saccadic and manual responses

Bimanual parityjudgments about numerically small (large) digits are faster with the left (right) hand, even though parity is unrelated to numerical magnitude per se (the SNARC effect; Dehaene, Bossini, & Giraux, 1993). According to one model, this effect reflects a space-related representation of numerical magnitudes (mental number line) with a genuine left-to-right orientation. Alternatively, it may simply reflect an overlearned motor association between numbers and manual responses--as, for example, on typewriters or computer keyboards--in which case it should be weaker or absent with effectors whose horizontal response component is less systematically associated with individual numbers. Two experiments involving comparisons of saccadic and manual parity judgment tasks clearly support the first view; they also establish a vertical SNARC effect, suggesting that our magnitude representation resembles a number map, rather than a number line.
