Superior detection of threat-relevant stimuli in infancy

The ability to quickly detect potential threat is an important survival mechanism for humans and other animals. Past research has established that adults have an attentional bias for the detection of threat-relevant stimuli, including snakes and spiders as well as angry human faces. Recent studies have documented that preschool children also detect the presence of threatening stimuli more quickly than various non-threatening stimuli. Here we report the first evidence that this attentional bias is present even in infancy. In two experiments, 8- to 14-month-old infants responded more rapidly to snakes than to flowers and more rapidly to angry than to happy faces. These data provide the first evidence of enhanced visual detection of threat-relevant stimuli in infants and hence offer especially strong support for the existence of a general bias for the detection of threat in humans.     

Medial temporal lobe memory in childhood: developmental transitions

The medial temporal lobes (MTL) support declarative memory and mature structurally and functionally during the postnatal years in humans. Although recent work has addressed the development of declarative memory in early childhood, less is known about continued development beyond this period of time. The purpose of this investigation was to explore MTL‐dependent memory across middle childhood. Children (6 –10 years old) and adults completed two computerized tasks, place learning (PL) and transitive inference (TI), that each examined relational memory, as well as the flexible use of relational learning. Findings suggest that the development of relational memory precedes the development of the ability to use relational knowledge flexibly in novel situations. Implications for the development of underlying brain areas and ideas for future neuroimaging investigations are discussed.     

By name or by deed? Identifying the source of the feminist stigma

Prejudice and discrimination against feminists were explored across two contexts, a workplace and a social setting. We examined university students' reactions to a woman who called herself a feminist, behaved like a feminist by challenging sexism, did both, or did neither. In Study 1, participants (N = 177) evaluated a job candidate less favorably when she called herself a feminist after controlling for perceived assertiveness and participants' feminist self‐identification. However, our results showed no evidence of hiring discrimination. In Study 2, participants (N = 184) evaluated a peer less favorably and were less willing to befriend and date her when she called herself a feminist, controlling for perceived assertiveness. Participants were also less willing to befriend her when she behaved like a feminist. The contextual nature of the feminist stigma and the influence of perceived assertiveness are discussed.     

What's so special about slithering serpents? Children and adults rapidly detect snakes based on their simple features

Snakes are among the most common targets of fears and phobias around the world. In visual search tasks, both adults and young children have repeatedly been found to visually detect snakes more rapidly than other kinds of stimuli. An important question that remains unstudied is what accounts for humans’ rapid response to snakes? Here we suggest that specific features of snakes themselves lead to their rapid detection. The results of five experiments suggest that a snake's shape is the crucial factor in their rapid detection.     

What makes an angry face look so … angry? Examining visual attention to the shape of threat in children and adults

Threatening facial expressions like anger can signal potential danger. Past research has established that both adults and children have an attentional bias for angry faces, visually detecting their presence more quickly than happy or neutral faces. More recent research has suggested that specific features of angry faces (such as the downward-pointing “V” shaped brow) are the effective stimulus in their rapid detection. However, research examining this issue has only been done with adults. In the current research, we examine the detection of the features of the downward-pointing “V” in both adults and preschool children using a touchscreen visual search procedure. In two experiments, both adults and children detected the downward-pointing “V” more quickly than an upward-pointing “V”. As the first evidence that young children exhibit the same superior detection of the features of threatening facial expressions that adults do, this research provides important support for the existence of an evolved attentional bias for threatening stimuli.     

Examining the Effects of Social Bonds and Shame on Drug Recovery within an On-Line Support Community

Past research has demonstrated the utility of on-line support groups for individuals to form relationships and make connections. Additionally, some on-line communities have expanded to provide various types of support, particularly for deviant behavior. These virtual communities may be particularly indispensable to individuals who, out of fear of condemnation, are reluctant to seek traditional forms of social support. For purposes of this study, we examined how members of a substance abuse recovery on-line support group expressed feelings pertaining to their own substance abuse, as well as their processes of attempted or successful recovery. Using an inductive approach for our preliminary analysis, we first assessed which theories were most prevalent throughout the writers’ journals. We then used these theories, both Hirschi’s theory of social control and Braithwaite’s theory of reintegrative shaming, as frameworks to explore the differences between those who were in recovery and those who were still using.
