Amygdala or hippocampus inactivation after retrieval induces temporary memory deficit

The hypothesis that memory is stored through a single stage of consolidation that results in a stable and lasting long-term memory has been challenged by the proposition that reactivation of a memory induces reconsolidation of the memory. The reconsolidation hypothesis is supported by evidence that, under some conditions, post-retrieval treatments affecting amygdala and hippocampus functioning impair subsequent retention performance. We now report that repeated retention testing attenuates the performance impairment induced by post-retrieval reversible inactivation of the amygdala and hippocampus of rats induced by tetrodotoxin. These findings challenge the reconsolidation hypothesis and suggest that the post-retrieval retention performance impairment is best explained as due to temporary retrieval failure.     

The influence of materialism and ideal body internalization on body‐dissatisfaction and body‐shaping behaviors of young men and women: Support for the Consumer Culture Impact Model

Exposure to media images of the ‘body‐perfect’ ideal has been partly blamed for the pursuit of thinness among women and muscularity among men. Research has largely overlooked the materialistic messages frequently associated with these images. We present findings from two studies with Icelandic students aged 18–21, one focusing on young women (n = 303) and one on young men (n = 226), which test associations of materialistic and body‐perfect ideals with body dissatisfaction and excessive body shaping behaviors. In both studies, the internalization of materialistic values is strongly linked to the internalization of body‐perfect ideals: the thin‐ideal for young women, and the muscular‐ideal for young men. A materialist value orientation also predicted body dissatisfaction in both studies, and was linked to body shaping behaviors, albeit differently for young women and men. Thus, the research identifies materialism as a further correlate of both body dissatisfaction and excessive body‐shaping behaviors. The findings support Dittmar's ( 2008 ) Consumer Culture Impact Model, which proposes that the body‐perfect and ‘material good life’ ideals jointly impact well‐being.     

Not All Great Minds Think Alike: Systematic and Intuitive Cognitive Styles

Individuals process information and make decisions in different ways. Some plan carefully and analyze information systematically, whereas others follow their instincts and do what “feels right.” We aimed to deepen our understanding of the meaning of the intuitive versus systematic cognitive styles. Study 1 (N = 130, 39% female, M_age = 24) compared cognitive styles of arts, accounting, and mathematics students. Cognitive styles were associated with values (Study 2: N = 154, 123, 78; female = 59%, 49%, 85.9%; M_age = 22, 23, 27) and traits (Study 3: N = 77, 140, 151; female = 59%, 66%, 46%; M_age = 22, 25, 23), and they interacted with experience in predicting performance (Study 4: N = 63, 48% female, M_age = 23; Study 5: N = 44, 39% female, M_age = 23). All participants were Caucasian Israeli students. The systematic style was most frequent among accountants, and the intuitive style was most frequent among artists, validating the meaning of the styles. Systematic style was positively correlated with Conscientiousness and with security values and negatively correlated with stimulation values. The intuitive style had the opposite pattern and was also positively correlated with Extraversion. Experience improved rule‐based performance among systematic individuals but had no effect on intuitive ones. Cognitive style is consistent with other personal attributes (traits and values), with implications for decision making and task performance.     

Giving from a distance: Putting the charitable organization at the center of the donation appeal

Past research has shown repeatedly that people prefer donating to a single identified human victim rather than to unidentified or abstract donation targets. In the current research we show results countering the identifiable victim effect, wherein people prefer to donate to charitable organizations rather than to an identifiable victim. In a series of five studies, we manipulate temporal and social distance, examine a variety of donation targets, and measure intention to donate time or money as well as actual donations of money. We show that people are more willing to donate to a charitable organization when they are temporally or socially distant from the population in need. Willingness to donate to a specific person in need is higher when donors are temporally or socially close to the donation target. Furthermore, we demonstrate that (a) empathy mediates donations to a single victim, yet does not mediate donations to charitable organizations; (b) that donation giving to charitable organizations is unique and is not similar to donations to a group of victims. Theoretical and practical implications are discussed.     

An examination of the interactions between mothers and children with anxiety disorders

This study examined the association between parenting styles and mother and child anxiety. Maternal overinvolvement and negativity/criticism were evaluated during a speech preparation task (N = 135 dyads) and a Five Minute Speech Sample (FMSS) from mothers (N = 155). During the speech task interaction, mothers of anxious children (aged 4–16 years), regardless of their own anxiety, were observed to be more overinvolved than mothers of nonanxious children. Similarly, the FMSS showed that mothers of anxious children (aged 4–17 years) were more overprotective, self-sacrificing, or nonobjective than mothers of nonanxious children, irrespective of maternal anxiety status. No differences in maternal negativity were found on the speech task between any of the groups. However, the FMSS showed that mothers of anxious children were more critical than mothers of nonanxious children, regardless of maternal anxiety status. These results support the relationship between overinvolved, critical parenting and child anxiety, but suggest that maternal anxiety is not associated with increased overinvolvement or criticism. Theoretical implications are discussed.     

Changes in maternal expressed emotion toward clinically anxious children following cognitive behavioral therapy

The aim of this study was to determine whether maternal expressed emotion (criticism and emotional overinvolvement) decreased across treatment for childhood anxiety. Mothers of 48 clinically anxious children (aged 6-14 years) were rated on levels of criticism (CRIT) and emotional overinvolvement (EOI), as measured by a Five Minute Speech Sample (FMSS) from mothers, prior to and following cognitive behavioral therapy (CBT) for their children’s anxiety. Results showed a significant decrease in the proportion of mothers who expressed high levels of criticism and emotional overinvolvement from pretreatment to posttreatment. This finding suggests that interventions aimed at reducing symptoms of child anxiety can also result in a decrease of maternal expressed emotion (criticism and emotional overinvolvement).     

Obstacles to Personal Creativity between Brazilian and Mexican University Students: A Comparative Study

The study focused on personal obstacles to creativity between 385 Brazilian and 305 Mexican university students. The Obstacles to Personal Creativity Inventory, designed and validated by Alencar (1999b), was administered to these students. The results indicated that Lack of Time/Opportunity was the most frequent obstacle. Significant differences were observed between Brazilian and Mexican students in the cluster of obstacles named Lack of Motivation, and between male and female students in the cluster of obstacles named Inhibition/Shyness. The results point to several obstacles to personal creativity which are common among university students. These obstacles should be known by those involved in education in order for them to help students to be less susceptible to obstacles that hinder their creativity.
