Mortality salience and the desire for offspring

Research on terror management theory (TMT) illustrates that following mortality salience (MS) people defend their cultural worldviews and bolster self-esteem to transcend death. Recently, research additionally showed that MS increased self-reports of the number of children desired in Dutch men but not in Dutch women. We conducted three studies to further investigate the role of desire for offspring in terror management. In Study 1, we conceptually replicated previous findings for Germany and found increased desire for offspring following MS in both men and women. Extending prior research Study 2 revealed that following MS not only was the accessibility of death-related thoughts increased, but also the accessibility of thoughts related to offspring. Finally, Study 3 suggested that the MS effect on ingroup bias was eliminated under conditions of offspring salience. Relating these findings to TMT, anticipated or actual offspring is discussed as a buffer against existential anxiety.     

Does empathy predict adolescents' bullying and defending behavior?

Through structural equation modeling, this study tested a path of relations in which different levels of empathic responsiveness were posited to be differently associated to bullying and defending behavior. Three hundred and eighteen Italian adolescents (142 girls and 176 boys; mean age = 13.2 years) completed the Davis's Interpersonal Reactivity Index [Davis, 1983] for empathy and the Participant role scales [Salmivalli et al., 1996] for bullying and defending behavior. The results revealed that the model fitted the data adequately, but only in the case of boys. As hypothesized, low levels of empathic responsiveness were associated to students' involvement in bullying others. In contrast, empathy was positively associated with actively helping victimized schoolmates. However, the estimates algorithm did not reach convergence with girls' data. The current findings confirm and extend the literature on the relation between empathy, prosociality and aggressive behavior. Educational implications are also discussed.     

Age and Assessments of Professional Expertise: The Relationship between Higher Level Employees’ Age and Self‐assessments or Supervisor Ratings of Professional Expertise

In this article the relationship between higher level employees’ age and assessments of professional expertise is described. Hypotheses have been tested with original survey data from 417 higher level employees and 224 direct supervisors. Concerning the analyses of the effects of age, our hypotheses have for the greater part been confirmed. In our study, we have found that age‐related stereotyping is an important phenomenon where assessments concerning professional expertise are made by supervisors. As regards the self‐ratings, there is no relationship between age and professional expertise. Further research is needed to understand the pattern of differences between the two types of ratings. Some speculations concerning improvements of the measurements are discussed.     

A psychometric evaluation of the Temperament in Middle Childhood Questionnaire (TMCQ) in a Swedish sample

Personality is generally considered to be biologically founded in temperament, and temperamental qualities have proven to be relatively stable across childhood and into adulthood (Caspi, Roberts & Shiner, 2005 ). Temperament predicts important developmental outcomes such as academic performance (Muris, 2006 ), and social functioning (Eisenberg, Fabes, Guthrie & Reiser, 2000 ), and it has also been found to be strongly related to the etiology and maintenance of internalizing and externalizing psychopathology in children (Muris, Meesters & Blijlevens, 2007 ; Nigg, 2006 ). To allow for the possibility of making early interventions, identification of potential risk factors (such as temperamental dispositions) is of great importance (Rettew & McKee, 2005 ). As temperament is multidimensional and has many different manifestations, parents and teachers are valuable sources in providing information about children's temperament (Rothbart & Bates, 2006 ; Tackett, Slobodskaya, Mar et al., 2012 ), and caregiver questionnaires are frequently used in child personality research. However, such questionnaires are only useful if their reliability and validity have been established. The aim of the present study was to examine the psychometric properties of the Temperament in Middle Childhood Questionnaire (TMCQ; Simonds, Kieras, Rueda & Rothbart, 2007 ), which focuses specifically on the ages between 7 and 11 years. The TMCQ is the least validated of the Rothbart measures, and although reliability data have been presented, together with some validity data, for a computerized self‐report version of the questionnaire (Simonds & Rothbart, 2004 ), information about the reliability and validity for the caregiver version is scant. In the present paper, we report such data for a Swedish sample.     

The Police Officer Tacit Knowledge Inventory (POTKI): Towards Determining Underlying Structure and Applicability as a Recruit Screening Tool

Summary The purpose of this research was to examine the potential application of the police officer tacit knowledge inventory (POTKI) as a police recruit screening tool. The POTKI is a situational judgment test and consists of knowledge gained on the job by experienced officers that is thought to be important for problem‐solving. In the present study, four police agencies from a western US state administered the POTKI along with other screening measures to police applicants. Performance of the novice recruits was subsequently rated by their supervisors using the measure of professional expertise (MOE). Principal component analysis, multiple regression analysis, and multivariate analysis of variance were conducted on the POTKI response options. POTKI response options were found to be predictive of supervisor MOE ratings. Principal component analysis results identified intrapersonal tacit knowledge components that predicted MOE metacognitive, skill, and social recognition supervisor ratings and distinguished novice from expert police officers.Copyright © 2017 John Wiley & Sons, Ltd.     

Visual motion influences the contingent auditory motion aftereffect

In this study, we show that the contingent auditory motion aftereffect is strongly influenced by visual motion information. During an induction phase, participants listened to rightward-moving sounds with falling pitch alternated with leftward-moving sounds with rising pitch (or vice versa). Auditory aftereffects (i.e., a shift in the psychometric function for unimodal auditory motion perception) were bigger when a visual stimulus moved in the same direction as the sound than when no visual stimulus was presented. When the visual stimulus moved in the opposite direction, aftereffects were reversed and thus became contingent upon visual motion. When visual motion was combined with a stationary sound, no aftereffect was observed. These findings indicate that there are strong perceptual links between the visual and auditory motion-processing systems.     

Amygdala and Periaqueductal Gray Lesions Only Partially Attenuate Unconditional Defensive Responses in Rats Exposed to a Cat

Defensive responses to a cat were observed in rats given excitotoxic lesions of the central nucleus of the amygdala (ACe), dorsolateral periaqueductal gray (dlPAG), ventral periaqueductal gray (vPAG), or sham lesions. Rats were placed adjacent to a compartment containing a cat. Sham-lesioned rats avoided the area nearest the cat and preferred the area furthest away from the cat. They also exhibited numerous defensive responses including, climbing, escape from the apparatus, and freezing. Rats with lesions of the ACe reacted like the sham lesioned rats by preferring the area of the apparatus furthest from the cat, however they climbed and escaped significantly less than sham lesioned rats. Avoidance of the area adjacent to the cat was attenuated in rats with lesions of the vPAG. Climbing along the walls of the apparatus was also attenuated in rats with lesions of the vPAG. Escapes from the apparatus were not significantly reduced by lesions of the vPAG and dlPAG. Thus, ACe lesions attenuated climbing and eliminated escapes, but did not impair locomotion of the rat away from the cat.     

A mental number line in human newborns

Humans represent numbers on a mental number line with smaller numbers on the left and larger numbers on the right side. A left‐to‐right oriented spatial–numerical association, (SNA), has been demonstrated in animals and infants. However, the possibility that SNA is learnt by early exposure to caregivers’ directional biases is still open. We conducted two experiments: in Experiment 1, we tested whether SNA is present at birth and in Experiment 2, we studied whether it depends on the relative rather than the absolute magnitude of numerousness. Fifty‐five‐hour‐old newborns, once habituated to a number (12), spontaneously associated a smaller number (4) with the left and a larger number (36) with the right side (Experiment 1). SNA in neonates is not absolute but relative. The same number (12) was associated with the left side rather than the right side whenever the previously experienced number was larger (36) rather than smaller (4) (Experiment 2). Control on continuous physical variables showed that the effect is specific of discrete magnitudes. These results constitute strong evidence that in our species SNA originates from pre‐linguistic and biological precursors in the brain.     

Young at heart,old at work? Relations between age, (meta-)stereotypes,self-categorization,and retirement attitudes

The aims of this study were to examine how workers' negative age stereotypes (i.e., denying older workers' ability to develop) and negative meta-stereotypes (i.e., beliefs that the majority of colleagues feel negative about older workers) are related to their attitudes towards retirement (i.e., occupational future time perspective and intention to retire), and whether the strength of these relationships is influenced by workers' self-categorization as an “older” person. Results of a study among Dutch taxi drivers provided mixed support for the hypotheses. Negative meta-stereotypes, but not negative age stereotypes, were associated with fewer perceived opportunities until retirement and, in turn, a stronger intention to retire. Self-categorization moderated the relationships between negative age (meta-)stereotypes and occupational future time perspective. However, contrary to expectations, the relations were stronger among workers with a low self-categorization as an older person in comparison with workers with a high self-categorization in this regard. Overall, results highlight the importance of psychosocial processes in the study of retirement intentions and their antecedents.     

The Expanding World of Edward Tronick

Edward Tronick operates at the interface of empirical analysis of mother–infant communication, systems theories, and psychoanalysis. He has been a leader in the articulation of the implications of systems views for child development research. Systems views of mother–infant interaction, and of development more broadly, increasingly provide one theoretical underpinning for psychoanalysis. His work has enriched our understanding of interactive models of the dyad, of development, and of the mind. He has made a pivotal contribution to the development of a relational systems approach to infant research and its implications for adult treatment.
