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.     

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.     

When less is more: Line drawings lead to greater boundary extension than do colour photographs

Is boundary extension (false memory beyond the edges of the view) determined solely by the schematic structure of the view or does the quality of the pictorial information impact this error? To examine this, colour photographs or line-drawings of 12 multi-object scenes (Experiment 1: N=64) and 16 single-object scenes (Experiment 2: N=64) were presented for 14 s each. At test, the same pictures were each rated as being the “same”, “closer-up”, or “farther away” (five-point scale). Although the layout, the scope of the view, the distance of the main objects to the edges, the background space and the gist of the scenes were held constant, line drawings yielded greater boundary extension than did their photographic counterparts for multi-object (Experiment 1) and single-object (Experiment 2) scenes. Results are discussed in the context of the multisource model and its implications for the study of scene perception and memory.     

Challenging ‘Belief’ and the Evangelical Bias: Student Christianity in English Universities

Abstract

Popular and academic accounts of university-based religion tend to privilege evangelical Christianity, presented as a morally conservative, conversionist movement at odds with university contexts, which are widely assumed to be vehicles for a progressive Western modernity. This is especially the case in the UK, given the association of higher education with secularisation, yet virtually no research has studied this interface by examining the lives of students. This article discusses findings from the three-year project “Christianity and the University Experience in Contemporary England”, including a nation-wide survey of undergraduate students, in examining how the experience of university shapes on-campus expressions of Christian identity. We argue that a sizeable constituency of undergraduates self-identify as ‘Christian’, but evangelicals emerge not as the dominant majority, but as a vocal minority. The emerging internal complexity is masked by a public discourse that conceives of religion in terms of propositional belief and presents evangelicalism as its pre-eminent form.     

Representation of mental illness in Christian self-help bestsellers

The present study examined messages about mental illness in 14 contemporary Christian self-help bestsellers. Content analysis revealed that most texts focused upon depression. Categories of textual units included Underlying Assumptions Regarding Depression, Representations of Depression, Roots/Causes/Reasons for Depression, and Christian Responses to Depression. Demonic influence was the most frequently cited reason for depression. Other reasons included negative cognitions, failure as a Christian, and negative emotions. Christian responses to depression included trusting God, religious activity, and individual willpower. Discussion of these results focused upon the problematic impact of these messages upon individuals with depression, and upon suggestions for reducing mental illness stigma in religious communities.     

The diagnosticity of color for emotional objects

Object classification can be facilitated if simple diagnostic features can be used to determine class membership. Previous studies have found that simple shapes may be diagnostic for emotional content and automatically alter the allocation of visual attention. In the present study, we analyzed whether color is diagnostic of emotional content and tested whether emotionally diagnostic hues alter the allocation of visual attention. Reddish-yellow hues are more common in (i.e., diagnostic of) emotional images, particularly images with positive emotional content. An exogenous cueing paradigm was employed to test whether these diagnostic hues orient attention differently from other hues due to the emotional diagnosticity. In two experiments, we found that participants allocated attention differently to diagnostic hues than to non-diagnostic hues, in a pattern indicating a broadening of spatial attention when cued with diagnostic hues. Moreover, the attentional broadening effect was predicted by self-reported measures of affective style, linking the behavioral effect to emotional processes. These results confirm the existence and use of diagnostic features for the rapid detection of emotional content.     

Mother–infant interaction improves with a developmental intervention for mother–preterm infant dyads

While premature infants have a high need for positive interactions, both infants and their mothers are challenged by the infant‘s biological immaturity. This randomized clinical trial of 198 premature infants born at 29–34 weeks gestation and their mothers examined the impact of the H-HOPE (Hospital to Home: Optimizing the Infant's Environment) intervention on mother–premature infant interaction patterns at 6-weeks corrected age (CA). Mothers had at least 2 social environmental risk factors such as minority status or less than high school education. Mother–infant dyads were randomly assigned to the H-HOPE intervention group or an attention control group. H-HOPE is an integrated intervention that included (1) twice-daily infant stimulation using the ATVV (auditory, tactile, visual, and vestibular-rocking stimulation) and (2) four maternal participatory guidance sessions plus two telephone calls by a nurse-community advocate team. Mother–infant interaction was assessed at 6-weeks CA using the Nursing Child Assessment Satellite Training–Feeding Scale (NCAST, 76 items) and the Dyadic Mutuality Code (DMC, 6-item contingency scale during a 5-min play session). NCAST and DMC scores for the Control and H-HOPE groups were compared using t-tests, chi-square tests and multivariable analysis. Compared with the Control group (n = 76), the H-HOPE group (n = 66) had higher overall NCAST scores and higher maternal Social-Emotional Growth Fostering Subscale scores. The H-HOPE group also had significantly higher scores for the overall infant subscale and the Infant Clarity of Cues Subscale (p < 0.05). H-HOPE dyads were also more likely to have high responsiveness during play as measured by the DMC (67.6% versus 58.1% of controls). After adjustment for significant maternal and infant characteristics, H-HOPE dyads had marginally higher scores during feeding on overall mother–infant interaction (β = 2.03, p = 0.06) and significantly higher scores on the infant subscale (β = 0.75, p = 0.05) when compared to controls. In the adjusted analysis, H-HOPE dyads had increased odds of high versus low mutual responsiveness during play (OR = 2.37, 95% CI = 0.97, 5.80). Intervening with both mother and infant is a promising approach to help premature infants achieve the social interaction patterns essential for optimal development.
