IQ decline following early unilateral brain injury: a longitudinal study

We examine whether children with early unilateral brain injury show an IQ decline over the course of development. Fifteen brain injured children were administered an IQ test once before age 7 and again several years later. Post-7 IQ scores were significantly lower than pre-7 IQ scores. In addition, pre-7 IQ scores were lower for children with larger lesions, but children with smaller lesions and higher pre-7 IQ scores showed a greater IQ decline over time. These findings suggest that the cognitive outcomes of children with early lesions, particularly those with relatively small lesions, change over the course of development.     

Screening for Specific Language Impairment in Preschool Children: Evaluating a Screening Procedure Including the Token Test

Specific language impairment (SLI) comprises impairments in receptive and/or expressive language. Aim of this study was to evaluate a screening for SLI. 61 children with SLI (SLI-children, age-range 4–6 years) and 61 matched typically developing controls were tested for receptive language ability (Token Test—TT) and for intelligence (Wechsler Preschool-and-Primary-Scale-of-Intelligence—WPPSI). Group differences were analyzed using t tests, as well as direct and stepwise discriminant analyses. The predictive value of the WPPSI with respect to TT performance was analyzed using regression analyses. SLI-children performed significantly worse on both TT and WPPSI (\(p \le .0001\)). The TT alone yielded an overall classification rate of 79%, the TT and the WPPSI together yielded an overall classification rate of 80%. TT performance was significantly predicted by verbal intelligence in SLI-children and nonverbal intelligence in controls whilst WPPSI subtest arithmetic was predictive in both groups. Without further research, the Token Test cannot be seen as a valid and sufficient tool for the screening of SLI in preschool children but rather as a tool for the assessment of more general intellectual capacities. SLI-children at this age already show impairments typically associated with SLI which indicates the necessity of early developmental support or training. Token Test performance is possibly an indicator for a more general developmental factor rather than an exclusive indicator for language difficulties.     

Substitutes for leadership in anaesthesia teams and their impact on leadership effectiveness

In this study we aim to increase our understanding of leadership in anaesthesia teams by investigating the relationship between substitutes for leadership, leadership behaviour, and team performance in situations with varying levels of routine and standardization. The present study relied on video recordings of 12 anaesthesia teams in a simulated setting with the occurrence of a nonroutine event. Clinical team performance was measured by the speed of adequate team reaction to this event. The leadership behaviours observed were coded either as content oriented (e.g., information transmission) or structuring (e.g., assigning tasks). Results showed that leadership behaviour changed depending upon the level of routine of a situation, the degree of standardization, and, to some extent, on the experience of team members. Leadership tends to be positively related to team performance during nonroutine and low standardized situations but negatively related to team performance in routine and highly standardized situations. Furthermore, leadership is only slightly related to team member experience. This study improves our understanding of influences of substitutes for leadership on successful leadership behaviour in anaesthesia teams. The findings also lead to suggestions for both further research and the enhancement of team leadership in critical care.     

A Tale of Two Standards: An Examination of Young Adults�� Endorsement of Gendered and Ageist Sexual Double Standards

Current North American sexual standards allow women to be sexual within committed relationships but may still restrict women??s sexuality to a greater extent than men??s. We investigated whether these gender double standards interact with an age double standard that describes the elderly as less sexual than the young, to create particularly limiting sexual standards for older women. 305 Canadian undergraduates completed a 2 (target age) × 2 (target gender) × 2 (participant gender) within-subjects study measuring perceptions of younger (own age) and older (over 65 years old) men??s and women??s interest in traditional sex (e.g., cuddling, intercourse with main partner) and experimental sex (e.g., extra-relationship sex, viewing erotic materials). ANCOVAs controlling for ageist and sexist beliefs revealed the ageist double standard; the elderly were perceived to be less interested in sex overall than the young. There was also a sexual double standard; women were perceived to be more interested in traditional sex than men, and men more interested in experimental sex than women. For traditional sex, women perceived younger targets as more interested than the older targets, and women targets as more interested than men. For experimental sex, a three-way interaction showed the interplay between the sexual and ageist double standards. Elderly female targets were perceived as least interested, and young male targets as most interested. Results reinforce that the current sexual standards distinguish between sex for intimacy and sex for other reasons (e.g., pleasure) and that the standards are particularly restrictive for older women.     

The role of self-aspects in emotions elicited by threats to physical health

In two studies, we examined the relationship between self-aspects and socially engaging and socially disengaging emotions elicited by imagined and real physical health problems. In Study 1, participants imagined themselves experiencing a health problem described in a hypothetical scenario and rated the extent to which they would experience a list of emotions. The experience of socially engaging emotions such as shame and embarrassment was predicted by the endorsement of collective self. In Study 2, participants recalled a past health problem and emotions they experienced during its course. Again, collective self predicted the extent to which people mentioned socially engaging emotions in their free recall of emotions. Independent self was not related to the imagined experience of socially disengaging emotions in Study 1 or the recollection of such emotions in Study 2.     

Gender Differences in Responding to Conflict in the Workplace: Evidence from a Large Sample of Working Adults

This investigation tested for gender effects in conflict behaviors by examining the ratings made by the bosses, peers, and subordinates of over 2,000 working adults participating in leadership development programs conducted in the U.S.; the effects of two confounding factors—age and organizational status—were controlled in all analyses. Consistent with predictions derived from a gender role analysis, women were rated as significantly more likely to engage in almost every constructive behavior. Also as predicted, men were rated as more likely to engage in active destructive behaviors. Rater gender had no effect for peers and subordinates, but female bosses made more positive ratings of targets than male bosses. In general, bosses rated targets somewhat higher on passive responses.     

Perceptions of Partner Violence: How Aggressor Gender,Masculinity/Femininity,and Victim Gender Influence Criminal Justice Decisions

This study examines the extent to which perceptions of partner violence are influenced by aggressor gender and masculinity/femininity, and victim gender. Participants evaluated a case scenario depicting domestic assault. Results found charges were significantly higher and sentences significantly longer when the victim was female. Masculine aggressors were more likely to be perceived as having threatened bodily injury and as having initiated the assault compared to feminine aggressors. Masculine aggressors in heterosexual relationships were more likely to be identified as having initiated an assault compared to feminine aggressors in heterosexual relationships or individuals in same-sex relationships.     

Pigeons use item-specific and category-level information in the identification and categorization of human faces

Three experiments examined the pigeon's ability to adapt to the specific tasks of identification and categorization of complex visual stimuli by attending to information at different levels of abstraction. In Experiment 1, pigeons were successively trained to discriminate first between pairs of human faces from the same sex and then between male and female faces. A final test revealed that the associations formed in the first training phase did not survive categorization training, indicating that the pigeons used item-specific information to discriminate faces of the same sex, but shifted their attention to category-level information for discriminating between the male and female categories. Two further experiments disproved alternative explanations. The results support the feature-learning account of open-ended categorization in animals.     

Signs of Socioeconomic Status: A Thin-Slicing Approach

ABSTRACT— Socioeconomic status (SES) is a primary determinant of health vulnerabilities and social affiliations. To ascertain if SES is signaled in brief patterns of nonverbal behavior, we had participants of varying SES backgrounds engage in a brief interaction with a stranger. Videos of 60-s slices of these interactions were coded for nonverbal cues of disengagement and engagement, and estimates of participants' SES were provided by naive observers who viewed these videos. As predicted by analyses of resource dependence and power, upper-SES participants displayed more disengagement cues (e.g., doodling) and fewer engagement cues (e.g., head nods, laughs) than did lower-SES participants. Results were also consistent with the thin-slicing literature, in that observers' estimates of SES were reliable with each other and accurately predicted targets' family income, maternal education, and subjective SES. Finally, nonverbal displays of disengagement and engagement predicted observers' estimates of SES, which suggests that these cues are systematic signs of SES. These results have implications for understanding the effect of SES on social interactions and patterns of disengagement and engagement in other realms.     

Outcomes and intentions in children’s,adolescents’, and adults’ second- and third-party punishment behavior

Theories of morality maintain that punishment supports the emergence and maintenance of moral behavior. This study investigated developmental differences in the role of outcomes and the violator’s intentions in second-party punishment (where punishers are victims of a violation) and third-party punishment (where punishers are unaffected observers of a violation). Four hundred and forty-three adults and 8-, 12-, and 15-year-olds made choices in mini-ultimatum games and newly-developed mini-third-party punishment games, which involved actual incentives rather than hypothetical decisions. Adults integrated outcomes and intentions in their second- and third-party punishment, whereas 8-year-olds consistently based their punishment on the outcome of the violation. Adolescents integrated outcomes and intentions in second- but not third-party punishment.
