The effect of spatial frequency information and visual similarity in threat detection

In the current research, we sought to examine the role of spatial frequency on the detection of threat using a speeded visual search paradigm. Participants searched for threat-relevant (snakes or spiders) or non-threat-relevant (frogs or cockroaches) targets in an array of neutral (flowers or mushrooms) distracters, and we measured search performance with images filtered to contain different levels (high and low) of spatial frequency information. The results replicate previous work demonstrating more rapid detection of threatening versus non-threatening stimuli [e.g. LoBue, V. & DeLoache, J. S. (2008). Detecting the snake in the grass: Attention to fear-relevant stimuli by adults and young children. Psychological Science, 19, 284–289. doi:10.1111/j.1467-9280.2008.02081.x]. Most importantly, the results suggest that low spatial frequency or relatively coarse levels of visual information is sufficient for the rapid and accurate detection of threatening stimuli. Furthermore, the results also suggest that visual similarity between the stimuli used in the search tasks plays a significant role in speeded detection. The results are discussed in terms of the theoretical implications for the rapid detection of threat and methodological implications for properly accounting for similarity between the stimuli in visual search studies.     

Tolerance of Sexual Harassment: An Examination of Gender Differences,Ambivalent Sexism,Social Dominance,and Gender Roles

In this study we examined the effects of gender, gender roles (masculinity and femininity), ambivalent sexism, and social dominance orientation with regard to tolerance of sexual harassment. It was predicted that women would be less tolerant than men of sexual harassment, however, men and women who were tolerant of sexual harassment would share ambivalence and hostility toward women, and they would exhibit higher levels of social dominance and masculinity. Results partially supported the hypotheses. Women were significantly less tolerant of harassment than men were, however, regression analyses showed that ambivalent sexism and hostility toward women accounted for the majority of total variance (35%), followed by gender (5%), social dominance (1%), femininity (0.7%), and nonsexism (0.6%). Masculinity and benevolent sexism were not significant predictors. Results suggest that ambivalence and hostility toward women are much greater predictors of tolerance of sexual harassment than is gender alone.     

Wanting a body that's better than average: the effect of manipulated body norms on ideal body size perception

We examined the effect of body norms on ideal and current body size perception. In Study One, female participants were randomly assigned to one of three experimental conditions: (1) a thinner body norm, (2) a heavier body norm, or (3) no body norm. Body norms were manipulated by indicating a bogus "population average," and current and ideal body size perception were subsequently measured using a body silhouettes measure. Women had a thinner ideal body size in the thinner norm condition than in the heavier norm condition. Study Two replicated these results, but in a sample of young men and with regards to muscularity rather than thinness. Men had a more muscular ideal body size in the more muscular norm condition than in the less muscular norm condition. Current body size perception was also influenced by body norms, but only for women and after controlling for BMI.     

Parental Strategies for Knowledge of Adolescents’ Friends: Distinct from Monitoring?

Parental monitoring is defined as a set of behaviors used to gain knowledge about an adolescent’s whereabouts, friends and associates, and activities. However, can knowledge of adolescents’ whereabouts/activities, and friends all be attained through the same strategies? Or do they require their own strategies? This study used qualitative interviews with 173 parents of older adolescents from 100 families. Emergent themes described strategies by which parents gain information about their adolescents’ friends and the substance use of those friends. The strategies included direct interaction with the friend, gaining information from the teen, using second-hand sources, and making assumptions. Some of these strategies were consistent with previous research, while others raise new questions and provide interesting new directions to pursue. Primarily, additional consideration needs to be given to assessments of parental monitoring that include strategies for gaining knowledge of adolescents’ friends and their substance use.     

Sibling jealousy in early childhood: longitudinal links to sibling relationship quality

The current investigation examined the long‐term prediction of sibling jealousy assessed in a laboratory‐based paradigm on sibling relationship quality 2 1/2 years later. This multi‐method longitudinal study included mothers, fathers, and two children from 35 families. Younger siblings were 16 months and older siblings were, on average, 4 years at Time 1. Positive longitudinal associations were found between older siblings' jealousy reactions when interacting with the father at Time 1 and sibling conflict at Time 2. These associations continued to exist even when older siblings' behaviour during the mother sessions was considered. Children's inability to regulate their jealous reactions may be indicative of lower levels of emotion regulation skills, which may, in turn, translate to poorer sibling interactions years later.
