Luminance affects age-related deficits in object detection: implications for computerized psychological assessments

As psychological instruments are converted for administration on computers, differences in luminance and contrast of these displays may affect performance. Specifically, high-luminance assessments may mask age-group differences that are apparent under lower luminance conditions. We examined the effects of luminance and contrast on object detection using computerized and naturalistic assessments. Younger and older adults displayed more differences in performance across differing contrast levels in conditions that were matched for luminance, despite the conditions appearing perceptually different. These findings indicate that computerized assessments should be created with luminance levels that are similar to those of the tasks they purport to simulate in order to enhance their validity.     

Predicting Feminist Identity: Associations Between Gender-Traditional Attitudes, Feminist Stereotyping, and Ethnicity

The connection between holding gender-traditional attitudes and the reluctance to identify as a feminist is well established, yet little is known about factors that might underlie this association. One factor that may serve this function is the tendency to hold negative stereotypes about feminists. Indeed, the constructs of ambivalent sexism (Glick and Fiske 1996) and ambivalence toward men (Glick and Fiske 1999) provide a strong theoretical basis for the prediction that traditional attitudes toward women and men are related to the derogation of women who do not conform to the feminine-stereotyped gender role. Therefore, the present study utilized path analysis to test a mediational model in which traditional attitudes toward women and men predict the tendency to stereotype feminists, which in turn predicts feminist identity. The present study also examined whether the relations between the variables in the model differed for African American, European American, and Latina women. Participants consisted of 544 women from the southern United States who, despite being undergraduates, were in their mid-to-late twenties on average. As expected, participant ethnicity moderated the paths in the model. Among African American and Latina women, hostility toward men and hostile sexism predicted the tendency to stereotype feminists, which then predicted feminist identity. Support for the mediational model was not obtained among European American women; instead, the model for European American women was characterized by direct paths from traditional attitudes toward women and men to feminist identity. Discussion focuses on the importance of considering participants’ ethnic background when assessing predictors of feminist identity.     

First-time parents' expectations about the division of childcare and play

The current study examines violated expectations regarding the division of childcare and play in first-time parents during the initial transition to parenthood. The study's goal was threefold: (a) to compare prenatal expectations with the reported postpartum division of childcare and play, (b) to compare the influence of the reported division versus violated expectations on postpartum relationship satisfaction and depression, and (c) to examine the role of persistent violations of expectations on these outcomes. Couples expecting their first child were interviewed during the third trimester of pregnancy and at 1 and 4 months postpartum. Results indicated both mothers and fathers have unrealistic expectations during pregnancy; interestingly, the direction violation was opposite but converging for mothers and fathers. As found in prior research, mothers experienced unmet expectations with fathers doing less than mothers expected. Fathers, on the other hand, experienced overmet expectations with mothers doing more than fathers expected. Violated expectations were also a stronger predictor of depression and relationship satisfaction than the reported division, although again in opposite directions for mothers and fathers. Unmet expectations were negative for mothers, while overmet expectations with regard to childcare tasks were beneficial for fathers. The one caveat was for fathers' overmet expectations with play; in this case, a mother playing with the baby more than a father expected was related to less relationship satisfaction. A similar pattern of results was found for mothers and fathers with persistent violations. This study highlights the importance of understanding violated expectations in both mothers and fathers, as well as examining play separately from childcare.     

Impact of emotional approach coping and hope on PTSD and depression symptoms in a trauma exposed sample of Veterans receiving outpatient VA mental health care services

The present investigation evaluates the relationship between coping style, dispositional hope, and posttraumatic stress disorder (PTSD) and depression symptom severity in a trauma-exposed Veteran sample. Specifically, we evaluated the adaptive value of emotional avoidant and approach coping strategies and perceptions of hope in a sample of 209 trauma-exposed Veterans receiving outpatient mental health care at a VA facility. Participants completed a life events questionnaire and inventories assessing coping, dispositional hope, and PTSD and depression symptom severity. Hierarchical regression analyses were conducted controlling for relevant demographic variables. Greater levels of emotional avoidance and lower levels of emotional expression were significantly associated with increased PTSD and depression symptom severity. Dispositional hope was positively associated with depression symptoms only and perceptions of hope moderated the association between emotional avoidance coping and depression symptoms. Findings highlight the value of emotional coping strategies and perceptions of hope in posttraumatic adjustment. Specifically, employing coping techniques that encourage emotional expression may promote improved adjustment among trauma-exposed individuals, while reduced perceptions of hope and the use of avoidant coping strategies may place individuals at greater risk for depression following exposure to traumatic events.     

An Approach to Examining the Proximal and Intermediate Outcomes of an Intensive Family Preservation Program

This study examined the effects of the Boys Town In-Home Family Program (BT-IHFP) on parenting skills, family functioning, and child behavior for at-risk families involved with child protective services. The BT-IHFP is designed as a home-based, family-centered alternative to out-of-home placement with the goal of improving family functioning, keeping families together, and preventing further involvement with child protective services. The model uses a hands-on cognitive-behavioral approach, promotes family engagement, provides 24/7 services to families, and links families to community resources. While it is essential to examine ultimate, long-term outcomes such as family preservation, it is also important to investigate the proximal and intermediate outcomes that address the key changes in behavior that support successful long-term outcomes. The goals of this study were to (1) examine the pre-post change of proximal and intermediate outcomes and (2) examine if improvements in parenting skills, parental roles, and parental stress (proximal outcomes) will be related to improvements in child behavior at home, child behavior at school, and family functioning (intermediate outcomes). Inspecting intake and discharge data for 44 families, 94% were intact at discharge and significant pre-post improvements were found in proximal and intermediate outcomes. These findings suggest that this six-week intensive BT-IHFP holds promise for teaching at-risk families skills to promote positive family functioning.     

In and out of consciousness: Sustained electrophysiological activity reflects individual differences in perceptual awareness

Although significant advances in our understanding of the cognitive and neural processes involved in conscious awareness have occurred in recent years, the precise mechanisms that support consciousness remain elusive. Examining the neural correlates associated with the moment a stimulus enters or exits conscious awareness is one way to potentially identify the neural mechanisms that give rise to consciousness. In the present study, we recorded neural activity using electroencephalography (EEG) while participants observed a bilateral shape-from-motion (SFM) display. While the display is in motion, the observer perceives an object that is immediately segregated from a noisy background. After the motion stops, the observer's experience of the object remains momentarily in awareness, before it eventually fades out of consciousness back into the noisy background. Consistent with subjective reports of perceptual experience, we observed a prominent sustained posterior contralateral negativity known as the contralateral delay activity (CDA). This activity was sustained only in conditions associated with sustained awareness. Interestingly, the amplitude of the CDA was correlated with individual differences in visual awareness, suggesting that this activity plays a significant role in the maintenance of objects in consciousness. The CDA is typically associated with visual short-term memory (VSTM), suggesting that conscious visual awareness may be mediated by the same neural and cognitive mechanisms that support VSTM. Our results demonstrate that the CDA may reflect the contents of conscious awareness, and therefore can provide a measure to track when information moves in and out of consciousness.     

Weighing in on risk factors for body dissatisfaction: a one-year prospective study of middle-adolescent girls

Body dissatisfaction is a common problem among adolescent girls that is linked to serious outcomes, including the development of eating disorders. This study tested to what degree five theorized risk factors (weight-related teasing, thin-ideal internalization, body mass index [BMI], self-esteem, and perfectionism) predicted prospective changes in body dissatisfaction. At baseline, 393 10th and 11th grade girls (M = 15.8 years) completed questionnaires and had their height and weight measured. One year later, 316 participants’ body dissatisfaction was reassessed (80.4% retention). Results suggested that self-esteem was the most potent risk factor, followed by BMI, when used to categorize girls into high- and low-risk groups for body dissatisfaction at follow-up. However, weight-related teasing, thin-ideal internalization, and perfectionism did not prove to be risk factors. These results suggest self-esteem and BMI are relevant variables for helping to identify middle-adolescent girls who may be at risk for subsequent increases in body dissatisfaction.     

Maternal Treatment Acceptability and Preference of Room Time-Out and Deferred Time-Out Escape Contingencies

ABSTRACT

Maternal preference and acceptability were examined for two methods of addressing time-out escape behavior: room time-out (RTO) and deferred time-out (DTO). With respect to preference, mothers were split about evenly. Spanking frequency and previous effectiveness using privilege removal were associated with preference for DTO while previous effectiveness using RTO was associated with preference for RTO. Child age was negatively associated with acceptability for either treatment and lax parenting style was negatively associated with acceptability for DTO. Results suggest that DTO could provide an alternative escape contingency for mothers who spank their children or who have been unsuccessful using RTO.     

Predicting Prosocial Behavior Toward Sex-Trafficked Persons: The Roles of Empathy,Belief in a Just World,and Attitudes Toward Prostitution

Human trafficking has been identified as a global human rights violation. This study aimed to investigate the predictors of prosocial behaviors toward sex-trafficked persons. Participants were 223 undergraduates randomly assigned to read a vignette and answer follow-up questions along with measures of empathy, just world belief, attitudes toward prostitution, and proactive behavior. Empathy was highest for trafficked women, regardless of citizenship status. Trafficked foreign women received the highest empathy, and U.S. prostitutes received the least. Path analysis results indicate just world belief, beliefs about prostitutes, and family values relating to prostitution had direct effects on empathic concern; in turn, empathic concern had a direct effect on proactive behavior. Explanations for the results are discussed, along with educational and clinical implications.
