Do children "DRM" like adults? False memory production in children

The Deese/Roediger-McDermott (DRM) paradigm was used to investigate developmental trends in accurate and false memory production. In Experiment 1, DRM lists adjusted to be more consistent with children's vocabulary were used with 2nd graders, 8th graders, and college students. Accurate and false recall and recognition increased with age, but semantic information appeared to be available to all age groups. Experiment 2 created a set of child-generated lists based on the free associations by a group of 3rd graders to critical items. The child-generated associates were different from those generated by adults; long and short versions of the child-generated lists were therefore presented to 2nd, 5th, and 8th graders and college students in Experiment 3. Second graders exhibited few false memories, whereas 5th graders were similar to adults in low-demand conditions and more similar to younger children in high-demand conditions. Findings are discussed in terms of developmental changes in automatic and effortful processing and the use of semantic networks.     

Distraction,attentional conflict,and drivelike behavior

Two studies provide evidence supporting a distraction-conflict view of social facilitation effects. Study 1 demonstrated that presence of an audience produced drivelike effects on the latency and vigor of a motor response. This effect, however, only occurred when attending to the audience caused attentional conflict. Study 2 demonstrated that in a two-task setting, attentional conflict, resulting from having to choose which task to work on, led to poorer performance on a complex copying task (p < .01, one tailed) and a larger percentage of dominant responses on J. L. Cohen and J. H. Davis' (Journal of Personality and Social Psychology, 1973, 27, 74–85) hidden word task (p < .04, one tailed), relative to a yoked control. Study 2 is consistent with earlier reports that choice heightens drivelike effects, while Study 1 indicates that attentional conflict contributes to social facilitation phenomena.     

The development of change detection

Changes to a scene often go unnoticed if the objects of the change are unattended, making change detection an index of where attention is focused during scene perception. We measured change detection in school-age children and young adults by repeatedly alternating two versions of an image. To provide an age-fair assessment we used a bimanual choice rather than open-ended verbal responses. The difference in detection speed and accuracy between 50-ms versus 250-ms blank screens between views indexed change detection in short-term visual memory independent of sensory and response processes. Younger children were significantly less efficient than older participants, especially when an object changed color or had a part deleted. Changes in object orientation were detected more readily. These results point to important differences in the perceptual reality of younger and older children.     

The Moderating Effect of Prior Experience in Consumers' Use of User-Image Based Versus Utilitarian Cues in Brand Attitude

In this paper, we address the question of whether prior experience with a product moderates the extent to which the use of user-image based cues and utilitarian cues are predictive of brand attitude. Specifically, high experience consumers were expected to focus more on utilitarian cues and low experience consumers to focus on user-image based cues. Results of two studies generally support these predictions.     

Unit Social Cohesion in the Israeli Military as a Case Study of “Don't Ask,Don't Tell”

U.S. military policy “Don't Ask Don't Tell” (DADT) restricted integration of gays in the U.S. military based on the premise that knowledge of gay peers would decrease interpersonal bonds among unit members. Despite the heated debate over DADT, this social cohesion thesis, reflecting the tensions of homosocial desire, has not been tested empirically. The Israeli military provides an operative case‐study for this thesis, given its nonexclusionary policy and intensive combat experience. Measures of perceived social cohesion and knowledge of gay peers were obtained from a sample of 417 combat and noncombat male soldiers using an inventory of interpersonal emotions towards unit members. A MANOVA of social cohesion by knowledge of gay peers and combat/noncombat unit yielded the hypothesized increase in cohesion in combat versus noncombat units. Yet contrary to the DADT premise, knowledge of gay peers did not yield decreased social cohesion. Comparisons with the U.S. military are presented, suggesting in both cases a loose coupling between stated policies and soldiers' experience on the ground. Implications of these findings for the reassessment of DADT and its repeal are discussed.     

Crime Type,Perceived Stereotypicality,and Memory Biases: A Contextual Model of Eyewitness Identification

The fallibility of eyewitness identifications is well documented. Nevertheless, research has yet to assess the possibility that the type of crime committed systematically influences who eyewitnesses mistakenly identify. We address this oversight by presenting a contextual model of eyewitness identification (CMEI). The CMEI asserts that discrete crimes automatically activate distinct stereotypes about a perpetrator's appearance. Depending on the congruence between these stereotypes and the perpetrator's actual appearance, eyewitnesses will remember the perpetrator as appearing more (or less) representative of his or her group (i.e., higher or lower on perceived stereotypicality). Estimator and system variables are posited to affect identifications at different stages of the identification process. The literatures on stereotype activation, perceived stereotypicality, and stereotype‐consistent memory biases are reviewed to support the CMEI. Our conceptual integration provides a model of eyewitness identification that explains when mistaken identifications are likely to occur and who they are likely to affect.
