Leadership and Perceiver Cognition: Examining the Role of Self-Identity in Implicit Leadership Theories

We investigated whether priming individuals' self-identities to be interdependent or independent influences their ratings of leadership prototypicality. Specifically, we predicted that participants receiving an interdependent prime would rate items associated with transformational leadership as being more prototypical of effective leadership than would participants receiving no prime. We also predicted that participants receiving an independent prime would rate transactional leadership items as being more prototypical of effective leadership. Undergraduate psychology students were randomly assigned to one of three conditions (interdependent prime, independent prime, and control). Results support the idea that self-identity can be primed to influence ratings of leadership prototypicality. We discuss implications and suggest directions for future research.     

The Relationship Between Deployment and Turnover in Australian Navy Personnel

Increases in the frequency of operations tempo have focused attention on the relationship between deployment and separation from military service. This retrospective study explored the association between deployment and turnover over a 10-year period in Royal Australian Navy (RAN) personnel. Participants were 2355 males who served in the RAN during the period of the 1991 Gulf War (August 1990–September 1991); approximately half had been deployed to that conflict. Data were collected 10 years later as part of the Australian Gulf War Veterans' Health Study. During that 10-year period, 61% of participants left the RAN. The likelihood of separation decreased as number of deployments increased even when controlling for age, rank, and length of service. Personnel deployed to the 1991 Gulf conflict did not have a significantly higher risk of separation. The results provide evidence that deployment is not necessarily a risk factor for separation.     

Neurobiological Correlates of Autism: A Review of Recent Research

This review paper integrates recent structural and functional imaging, postmortem, animal lesion, and neurochemical research about the pathophysiology of autism. An understanding of the neurobiological correlates of autism is becoming increasingly important as more children are diagnosed with the condition and funding for well-targeted interventions increases. Converging evidence suggests that autism involves abnormalities in brain volume, neurotransmitter systems, and neuronal growth. In addition, evidence firmly links autism with abnormalities in the cerebellum, the medial temporal lobe, and the frontal lobe. Potential implications of these findings and suggestions for future research are reviewed.     

Hospital referral patterns in pediatric neuropsychology

The practice of pediatric neuropsychologists was examined by reviewing all referrals made in 1 year to neuropsychology programs located in three children's hospitals. The review identified 472 cases, 75% of whom were between the ages of 7 and 11. The sample included 86 inpatients and 386 outpatients. The most common diagnoses, accounting for 87% of the cases, were learning disability, traumatic brain injury, attention deficit-hyperactivity disorder, seizure disorder, primary psychiatric disorder, phenylketonuria, idiopathic mental retardation, brain tumor, leukemia, stroke, and encephalitis. The most common referral sources, accounting for 92% of the cases, were neurologists, pediatricians, parents, physiatrists, neurosurgeons, oncologists, specialists in metabolic disease, psychologists, rheumatologists, and psychiatrists. The distribution of diagnoses and referral sources differed significantly for inpatients and outpatients and across the three hospitals. The results may distinguish child neuropsychology from adult neuropsychology and highlight the diversity that characterizes its practitioners.     

The Emotionality Activity Sociability Temperament Survey: Factor analysis and temporal stability in a longitudinal cohort

We investigated Buss and Plomin’s Emotionality Activity Sociability (EAS) Temperament Survey for Children, used to assess temperament. Temperament is believed to comprise stable traits that change little over time. We examined stability of EAS temperament in the Avon Longitudinal Study of Parents and Children, in which 7429 mothers completed the EAS when their children were 3, 5 and 6 years old. Factor analysis was conducted at each time point, and stability over time was assessed using correlation and mixed effects regression modelling, accounting for differences within and between individuals. A four-factor model provided the best fit, with 19–20 of the 20 items loading onto the dimensions predicted by Buss and Plomin. Test–retest correlations ranged from 0.52–0.64 (3–5 years), 0.59–0.74 (5–6 years) and 0.46–0.58 (3–6 years). Mixed effects regression modelling suggested good stability over time: differences between, rather than within, individuals accounted for between 69% and 82% of the variance. This study demonstrates the stability of temperament over time, a vital pre-requisite to investigating childhood temperament as a predictor of outcomes.     

Being moved by meaningfulness: appraisals of surpassing internal standards elicit being moved by relationships and achievements

ABSTRACT

People can be moved and overwhelmed, a phenomenon typically accompanied by goose-bumps and tears. We argue that these feelings of being moved are not limited to situations that are appraised as pro-social but elicited when someone surpasses an internal standard. In line with these predictions, people were moved by relationships and success (Study 1), by reunion, separation, success and failure (Study 2) and by social, environmental and sports achievements (Study 3). In all three studies, the elicitation of these feelings was partially mediated by appraisals of surpassing social or achievement standards. In line with this, ratings of meaningfulness were closely associated with feelings of being moved and moving stimuli elicited behavioural intentions such as spending time with family and friends, helping others and/or achieving something in life. Thus, moving situations may remind us about what we perceive as meaningful and thereby help us to act accordingly.     

Covert judgements are sufficient to trigger subsequent task-switching costs

This research examines whether we have a tendency to repeat mental processes leading to decisions or judgements that are not accompanied by overt behaviours. We adapted the task-switching paradigm so that on selected trials task processing would be terminated prior to response execution. Switch costs were present subsequent to trials where task processing was terminated either at the stage of response selection or at the earlier stage of making a covert judgement (a mental decision) about the target stimulus. These costs were residual, as they occurred despite long preparation intervals, and they did not result from cue-switching or feature-repetition effects. We conclude that the same type of control mechanism may be recruited to select between potential alternative tasks whenever a stimulus needs to be processed in a task-specific way, regardless of whether or not an overt response is required.     

Parent-Youth Rating Concordance for Hair Pulling Variables,Functional Impairment,and Anxiety Scale Scores in Trichotillomania

ABSTRACT

Knowledge of cross-informant rating concordance is critical for the assessment of child and adolescent problems in clinical and research settings. We explored parent-youth rating concordance for hair pulling variables, functional impairment, and anxiety symptoms in a sample of child and adolescent hair pullers (n = 133) satisfying conservative diagnostic criteria for trichotillomania (TTM). Whole group analyses reveal significant parent-youth agreement on all study variables. Split group analyses, however, reveal superior parent-youth concordance for the adolescent (15–17 years old) versus younger (10–12 years old) hair pullers for awareness of hair pulling and anxiety scale scores. These results highlight the need for both parent and youth ratings when assessing younger children with TTM.
