Dimension intertrial and cueing effects in localization: support for pre-attentively weighted one-route models of saliency

There are several alternative accounts of dimensional intertrial and cueing effects in singleton feature search tasks. Some accounts assume that these effects arise at post-selective processing stages; dual-route accounts assume them to be perceptual in nature, but coming into play only in non-spatial tasks (e.g., detection but not localization). By contrast, the Dimension Weighting Account (DWA) assumes dimensional effects to arise at pre-attentive processing stages of spatial as well as non-spatial tasks. The data available are ambiguous, permitting no clear-cut choice among these accounts. Therefore, the present study examined for early effects of dimensional weighting in a spatial task, the presence of which is only predicted by the DWA and not by post-selective or dual-route accounts. Salience is known to saturate for high feature contrast and long presentation times. Consequently, with lower bottom-up salience that still permits efficient search, dimensional weights would produce a greater modulation--if present at all. Thus, we examined localization accuracy under brief-presentation conditions in Experiment 1, and localization speed under conditions of low versus high feature contrast in Experiment 2. Both experiments revealed significant dimension intertrial and cueing effects. This strongly argues against dual-route accounts and strengthens evidence for a pre-attentive origin of these effects.     

Measuring perceptual centers using the phase correction response

The perceptual center (P-center) is fundamental to the timing of heterogeneous event sequences, including music and speech. Unfortunately, there is currently no comprehensive and reliable model of P-centers in acoustic events, so P-centers must instead be measured empirically. This study reviews existing measurement methods and evaluates two methods in detail-the rhythm adjustment method and a new method based on the phase correction response (PCR) in a synchronous tapping task. The two methods yielded consistent P-center estimates and showed no evidence of P-center context dependence. The PCR method appears promising because it is accurate and efficient and does not require explicit perceptual judgments. As a secondary result, the magnitude of the PCR is shown to vary systematically with the onset complexity of speech sounds, which presumably reflects the perceived clarity of a sound's P-center.     

Category-contingent face adaptation for novel colour categories: Contingent effects are seen only after social or meaningful labelling

A face appears normal when it approximates the average of a population. Consequently, exposure to faces biases perceptions of subsequently viewed faces such that faces similar to those recently seen are perceived as more normal. Simultaneously inducing such aftereffects in opposite directions for two groups of faces indicates somewhat discrete representations for those groups. Here we examine how labelling influences the perception of category in faces differing in colour. We show category-contingent aftereffects following exposure to faces differing in eye spacing (wide versus narrow) for blue versus red faces when such groups are consistently labelled with socially meaningful labels (Extravert versus Introvert; Soldier versus Builder). Category-contingent aftereffects were not seen using identical methodology when labels were not meaningful or were absent. These data suggest that human representations of faces can be rapidly tuned to code for meaningful social categories and that such tuning requires both a label and an associated visual difference. Results highlight the flexibility of the cognitive visual system to discriminate categories even in adulthood.     

Toward an understanding of situational judgment item validity and group differences

This paper evaluates 2 adjustments to common scoring approaches for situational judgment tests (SJTs). These adjustments can result in substantial improvements to item validity, reductions in mean racial differences, and resistance to coaching designed to improve scores. The first adjustment, applicable to SJTs that use Likert scales, controls for elevation and scatter (Cronbach & Gleser, 1953). This adjustment improves item validity. Also, because there is a White-Black mean difference in the preference for extreme responses on Likert scales (Bachman & O'Malley, 1984), these adjustments substantially reduce White-Black mean score differences. Furthermore, this adjustment often eliminates the score elevation associated with the coaching strategy of avoiding extreme responses (Cullen, Sackett, & Lievens, 2006). Item validity is shown to have a U-shaped relationship with item means. This holds both for SJTs with Likert score response formats and for SJTs where respondents identify the best and worst response option. Given the U-shaped relationship, the second adjustment is to drop items with midrange item means. This permits the SJT to be shortened, sometimes dramatically, without necessarily harming validity.     

Age-relevance of person characteristics: persons' beliefs about developmental change across the lifespan

The authors investigated normative beliefs about personality development. Young, middle-aged, and older adults indicated the age-relevance of 835 French adjectives by specifying person characteristics as typical for any age decade from 0 to 99 years. With this paradigm, the authors determined age-relevance (How typical is a characteristic for a given age decade?). Most characteristics were ascribed to young adulthood. The pattern differed across the lifespan, however, for positive and negative person characteristics as well as for physical, cognitive, and personal/expressive characteristics. Whereas the total number of ascribed positive characteristics peaked in young adulthood and declined thereafter, the number of ascribed negative person characteristics peaked during adolescence, remained fairly low during middle adulthood, and increased slightly in old age (70+ years). As a consequence, the most positive profile was ascribed to young olds (60 to 69 years), whereas the most negative personality profiles were ascribed to the oldest age groups (70+ years) and to adolescence (10 to 19 years). The negative profiles are primarily due to more negative physical characteristics ascribed to older adults and more negative cognitive characteristics ascribed to adolescence.     

Health and turnover of working mothers after childbirth via the work-family interface: an analysis across time

This study examined organizational levers that impact work-family experiences, participant health, and subsequent turnover. Using a sample of 179 women returning to full-time work 4 months after childbirth, we examined the associations of 3 job resources (job security, skill discretion, and schedule control) with work-to-family enrichment and the associations of 2 job demands (psychological requirements and nonstandard work schedules) with work-to-family conflict. Further, we considered subsequent impact of work-to-family conflict and enrichment on women's health (physical and mental health) 8 months after women returned to work and the impact of health on voluntary turnover 12 months after women returned to work. Having a nonstandard work schedule was directly and positively related to conflict, whereas schedule control buffered the effect of psychological requirements on conflict. Skill discretion and job security, both job resources, directly and positively related to enrichment. Work-to-family conflict was negatively related to both physical and mental health, but work-to-family enrichment positively predicted only physical health. Physical health and mental health both negatively influenced turnover. We discuss implications and opportunities for future research.     

Trauma-Focused CBT for Traumatic Grief in Military Children

Although military children are typically as resilient as the general child population, the ongoing conflict has exposed military children to unusual stressors such as repeated deployment, severe injury, or the death of a parent or sibling. U.S. forces have experienced more than 5,600 casualties during Operation Iraqi Freedom and Operation Enduring Freedom, with growing numbers of suicides among Service members. These deaths have affected thousands of military children. Most bereaved military children experience adaptive grief characterized by deep sadness, longing for the deceased person, and being comforted by positive memories of the deceased. A smaller number of military children develop childhood traumatic grief, characterized by trauma symptoms that interfere with adaptive grieving. Children with traumatic grief get “stuck” on the traumatic aspects of the death such as picturing the imagined or real details of the death; imagining the pain their loved one experienced in the moments before dying; wishing for revenge; and becoming angry at those who do not understand or share the child’s thoughts and feelings about the death. These children avoid reminders of the deceased person. Trauma-focused cognitive behavioral therapy (TF-CBT) is an evidence-based treatment for children with trauma symptoms including those with traumatic grief. TF-CBT may be particularly suitable for military families. This article describes the clinical application of TF-CBT for traumatic grief in military children.     

The Emotional Impact of Ambivalent Sexism: Forecasts Versus Real Experiences

Research on affective forecasting indicates that people regularly mispredict the emotional impact of negative events. We extended this work by demonstrating several forecasting errors regarding women’s affective reactions to ambivalent sexism. In response to a survey about sexism against women, students at a university in the Central U.S. (N?=?188) overestimated the negative impact of hostile sexism, and underestimated the negative impact of benevolent sexism, relative to women’s reports of their actual experiences. Moreover, people mispredicted both the intensity of women’s initial affective reactions to, and the duration of women’s recovery following, ambivalent sexism. The data supported a model in which inaccurate estimates of initial intensity fully accounted for people’s inaccurate estimates of recovery duration following ambivalent sexism.     

Deconstructing the tower: Parameters and predictors of problem difficulty on the Tower of London task

The Tower of London (TOL) task has been widely used in both clinical and research realms. In the current study, 104 healthy participants attempted all possible moderate- to high-difficulty TOL problems in order to determine: (1) optimal measures of problem solving performance, (2) problem characteristics, other than the minimum moves necessary to solve the problem, that determine participants’ difficulty in solving problems successfully, quickly, and efficiently, and (3) effects of increased task experience on which problem characteristics determine problem difficulty. A factor analysis of six performance measures found that, regardless of task experience, problem difficulty could be captured well either by a single factor corresponding to general quality of solution or possibly by three subordinate factors corresponding to solution efficiency, solution speed, and initial planning speed. Regression analyses predicting these performance factors revealed that in addition to a problem’s minimum moves three problem parameters were critical in determining the problem difficulty: goal position hierarchy, start position hierarchy, and number of solution paths available. The relative contributions of each of the characteristics strongly depended on which performance factor defined performance. We conclude that TOL problem performance is multifaceted, and that classifying problem difficulty using only the minimum moves necessary to solve the problem is inadequate.     

The Relationship of Differentiation,Family Coping Skills,and Family Functioning with Optimism in College-Age Students

The marriage and family therapy (MFT) field would benefit from new research about positive subjective experiences, such as optimism, in order to construct and nurture strengths for developing more positive emotions. Through a better understanding of optimism, marriage and family therapists (MFTs) can explore which strategies might help families and individuals better cope with distressing emotions by building buffering strengths. In this study we address the relationship of differentiation, family coping, and family functioning to optimism. We found that differentiation, family coping, and family functioning each have a significant effect on attributional style. The results of this study also indicated that encouraging clients to take an I-position and to reframe problems, in particular, may lead to greater optimism. This study contributes to the lack of research regarding strength-based theories in the MFT field.
