Meta‐Analysis of Clerical Performance Predictors: Still stable after all these years

Pearlman, Schmidt, and Hunter (1980) published a seminal paper on the validity of various measures for predicting performance in clerical jobs. They concluded that for both job and training performance criteria, 10 types of tests (e.g., perceptual speed, clerical aptitude, verbal ability) predicted performance across 5 clerical job families. This paper describes a psychometric meta‐analysis of validity studies using similar measures for clerical jobs conducted since 1980 to examine the stability of Pearlman and colleagues' validity estimates. This paper contributes to the literature by investigating the long‐term stability of validity generalization estimates over a period of several decades. Clerical jobs provide a compelling case study because these jobs have changed considerably due to the increased use of computers and technology in the office environment. Results showed that the mean population estimates in the present study were consistent with, or higher than, those obtained by Pearlman and colleagues, thus demonstrating the long‐term stability of meta‐analytic estimates of validity. The relative stability of the validity estimates also supports the robustness of g as a predictor, even as jobs change over time.     

The import of the cortisol rise in child care differs as a function of behavioral inhibition

Children of ages 3 to 4.5 years (N = 107; 45 boys, 62 girls) were studied twice, 6 months apart, to examine whether the cortisol rise in child care at Time 1 (T1) was associated with (a) changes in anxious, vigilant behavior from T1 to Time 2 (T2) and (b) higher internalizing symptoms at T2. Controlling for measures of home environment and child care quality at T1, as well as for cortisol activity at T2, we obtained results indicating that behavioral inhibition moderated the associations between the rise in cortisol at T1 and child outcomes at T2 (i.e., anxious, vigilant behavior and internalizing symptoms). For both outcomes, the rise in cortisol at T1 became more positively predictive at increasing levels of behavioral inhibition. Specifically, at higher levels of behavioral inhibition, children with larger T1 cortisol increases expressed more internalizing symptoms than did children at lower levels of behavioral inhibition; in contrast, for those with low cortisol activity at T1, children with higher levels of inhibition expressed fewer internalizing symptoms than did children at lower levels of inhibition. In addition, children with higher levels of behavioral inhibition and lower cortisol activity at T1 exhibited reductions in anxious, vigilant behavior from T1 to T2, whereas at lower levels of behavioral inhibition, variations in the T1 cortisol rise bore no relation to changes in this behavior. These results suggest that the rise in cortisol at child care may have differential predictive value as a function of behaviorally inhibited temperament.     

Associations between serotonin transporter gene promoter region (5-HTTLPR) polymorphism and gaze bias for emotional information

The serotonin transporter promoter region polymorphism (5-HTTLPR) is associated with neural response to negative images in brain regions involved in the experience of emotion. However, the behavioral implications of this sensitivity have been studied far less extensively. The current study used eye-tracking methodology to examine how individuals genotyped for the 5-HTTLPR, including the single nucleotide polymorphism (SNP) rs25531, allocated attention during prolonged (30-s) exposure to face stimuli depicting positive and negative emotion. Short 5-HTTLPR allele carriers and carriers of the long allele with guanine at the sixth nucleotide (S/LG) displayed a stronger gaze bias (total fixation time, number of fixations, mean fixation length) for positive than for sad, threat, or neutral stimuli. In contrast, those homozygous for the long 5-HTTLPR allele with adenine at the sixth nucleotide (LA) viewed the emotion stimuli in an unbiased fashion. Time course analyses indicated no initial 5-HTTLPR group differences; however, S/LG 5-HTTLPR allele carriers were more likely than LA 5-HTTLPR homozygotes to direct gaze toward happy than toward sad stimuli over time. This bias toward positive stimuli during the later stages of information processing likely reflects a strategic effort to downregulate heightened reactivity to negative stimuli among 5-HTTLPR S/LG allele carriers.     

Longitudinal associations between television viewing patterns and adolescent body satisfaction

This study addressed profiles of adolescent television use and associations between television viewing profiles and the development of body satisfaction. A sample of 841 adolescent boys and girls, ages 11-17, was recruited for participation in a longitudinal study of adolescent media use. Prior research established eight adolescent television profiles among this sample, reflecting unique patterns of consumption of certain genres, character types, and themes (e.g., romance). This study examined whether an adolescent's television profile predicted Time 2 body satisfaction, after controlling for Time 1 body satisfaction. Among boys, television viewing was unrelated to Time 2 body satisfaction. After controlling for initial body satisfaction, hours spent watching television marginally predicted lower Time 2 body satisfaction among girls. After including television profiles alongside television hours, however, television profile emerged as the stronger predictor. Specifically, a group of girls who watched television frequently and indiscriminately reported the most severe drop in body satisfaction.     

Women’s Perceptions of the Personal and Family Impact of Genetic Cancer Risk Assessment: Focus Group Findings

Women with a personal or family history of breast or ovarian cancer are increasingly presenting for genetic cancer risk assessment (GCRA). To explore the personal and family impact of GCRA, four focus groups were conducted of women seen for risk assessment. Participants were 22 primarily non-Latina White women with a personal or family history of breast or ovarian cancer. Analysis of the data identified new themes related to balancing time to assimilate risk information with the need to make timely healthcare decisions, physicians’ lack of sufficient genetic knowledge, and concern for daughters regardless of the daughters’ age. Other themes related to protecting others, knowledge as empowerment, reassessing personal attribution of cancer risk, managing uncertainty, reappraising body image, and experiencing divergent family responses to communication of cancer risk and healthcare decisions. Understanding the personal and family impact of GCRA may enable genetics professionals to tailor their counseling efforts to better meet the needs of these women. Additional research is needed to extend these findings and identify interventions to support positive outcomes of GCRA.     

What matters in the associative learning of visual cues in foraging parasitoid wasps: colour or brightness?

Visual cues are known to be used by numerous animal taxa to gather information on quality and localisation of resources. Because environmental lighting can interfere with the spectral features of visual cues, the specific characteristics of the colour signals that promote forager decision and learning are still not known in the majority of insects (excepted in bees). We analysed the effect of previous experience on the use of visual information by the wasp Venturia canescens, a parasitoid of pyralidae, in the context of host searching. These parasitoids search for hosts concealed in several fruit species, so visual cues from the host microhabitat could play a key role in host finding. We also investigated the type of visual cues on which wasps based their decision. We tested whether wasps are able to associate an achromatic cue (brightness) or a chromatic one (hue, i.e. dominant wavelength and/or chroma) with the presence of hosts. Our results show that in the context of host foraging, chromatic cues are more reliable than brightness in achieving the associative learning process. Therefore, understanding the behavioural ecology of foraging should make use of the knowledge about the visual information used.     

Emotional responses during social information seeking on Facebook

Based on existing research on social networking and information seeking, it was proposed that Facebook.com use could be conceptualized as serving two primary goals: passive social browsing (i.e., newsfeeds) and extractive social searching (i.e., friends' profiles). This study explored whether these categories adequately reflect Facebook use and whether they moderate physiological indicators of emotion. Thirty-six participants navigated Facebook.com while their on-screen activity and physiological responses associated with motivation and emotion were recorded. Results showed that the majority of screens encountered during Facebook use could be categorized as devoted to social browsing or social searching. Participants spent more time on social browsing than they spent on social searching. Skin-conductance data indicated that sympathetic activation diminished during the course of both social browsing and social searching. Facial EMG data indicated that participants experienced more pleasantness during the course of social searching than they experienced during social browsing. These results are discussed in terms of existing social-networking research and an evaluative space model of emotion.     

Testing a new cognitive behavioural treatment for obesity: A randomized controlled trial with three-year follow-up

It is remarkably difficult for people with obesity to maintain a new lower weight following weight loss. The aim of the present study was to examine the immediate and longer-term effects of a new cognitive behavioural treatment that was explicitly designed to minimise this post-treatment weight regain. One hundred and fifty female participants with obesity were randomized to the new treatment, behaviour therapy (the leading alternative psychological treatment) or guided self-help (a minimal intervention). Both of the main treatments resulted in an average weight loss of about ten percent of initial weight whereas weight loss was more modest with guided self-help. The participants were subsequently followed-up for three years post-treatment. The great majority regained almost all the weight that they had lost with the new treatment being no better than the behavioural treatment in preventing weight regain. These findings lend further support to the notion that obesity is resistant to psychological methods of treatment, if anything other than a short-term perspective is taken. It is suggested that it is ethically questionable to claim that psychological treatments for obesity “work” in the absence of data on their longer-term effects.     

Increasing response diversity in children with autism

Repetitive and invariant behavior is a diagnostic feature of autism. We implemented a lag reinforcement schedule to increase response diversity for 6 participants with autism aged 6 to 10 years, 4 of whom also received prompting plus additional training. These procedures appeared to increase the variety of building-block structures, demonstrating that an intervention that includes differential reinforcement can increase response diversity for children with an autism spectrum disorder.
