Using positive peer reporting to improve the social interactions and acceptance of socially isolated adolescents in residential care: a systematic replication

We studied how rewarding youth in residential care for publicly reporting positive social behavior influenced the social interactions and acceptance of their most socially isolated peers. Results showed that the intervention resulted in substantial improvements in social interactions by the previously isolated peers. Peer acceptance ratings also improved for 2 of the target youths.     

Implicit memory and test awareness

In three experiments we examined whether normal subjects can perform an implicit test without becoming aware that the test items were previously encountered in the study phase of the experiment. Experiment 1 assessed single word priming with the stem completion task, and subjects who reported awareness/unawareness that the test items were previously encoded in the study task showed equivalent priming. Experiments 2a-c and 3 assessed associative priming with the stem completion task, and in this case, only subjects who were aware that the test items were previously encountered showed associative priming effects. These findings suggest that single word priming and associative priming reflect different memory processes because the former and not the latter effect can be observed in unaware subjects.     

The visual system supports online translation invariance for object identification

The ability to recognize the same image projected to different retinal locations is critical for visual object recognition in natural contexts. According to many theories, the translation invariance for objects extends only to trained retinal locations, so that a familiar object projected to a nontrained location should not be identified. In another approach, invariance is achieved “online,” such that learning to identify an object in one location immediately affords generalization to other locations. We trained participants to name novel objects at one retinal location using eyetracking technology and then tested their ability to name the same images presented at novel retinal locations. Across three experiments, we found robust generalization. These findings provide a strong constraint for theories of vision.     

Social Learning,Self-Control,Gender, and Variety of Violent Delinquency

This study tested the role of social learning and self-control theories in the variety of violent delinquent behaviors engaged in by male and female adolescents (N = 833). Results of Tobit analyses indicated that neither theory was able to account for the gender gap. Low self-control was significantly associated with an increase in the variety of violent delinquency among females. Among male respondents, those who were more susceptible to peer pressure engaged in fewer types of violent delinquency. We conclude that theories must actively recognize the role of gender to better account for the differences in violent delinquent behavior.     

Gender Role Identity and the Caregiving Experience of Widowed Men

The relationship between gender role identityand caregiving experience was explored in a sample ofelderly widowed men. A total of 200 males (82.5%Caucasian) were interviewed 12 to 16 months after the death of their wives. Results indicated thatmen who had served as caregivers scored higher on themasculine dimension of the Bem Sex Role Inventory, andmasculinity was a significant predictor of well-being for both caregivers and noncaregivers.Following a cognitive dissonance model (Hirsch, 1996),the results do not support the adoption of feminine orandrogynous ideals as a way of coping with this life demand. Instead, the results add to the growingbody of work in support of a masculine model ofwell-being.     

Within-modal and cross-modal reliabilities of two laterality tests

Sixteen right handers were given four tests of a dichotic listening recall task (concrete words) and a visual half-field recall task (letters). There was a significant right ear and right visual half-field superiority for the four test sessions, with improvement in recall scores over sessions. Pearson correlations for each ear on the four dichotic tests ranged from .74 to .90. Correlations on the visual half-field scores, however, were significant only after the first session. Analysis of stability in lateral preferences across modalities revealed stable and reliable performance, particularly in the last two testings, where 81.3% of the subjects had a right-sided asymmetry. Cross-modal correlations, however, were not significant. Implications regarding predictions of speech laterality are discussed in the light of these findings.     

Cohesion and power in the families of children involved in bully/victim problems at school

The dimensions of Power and Cohesion have been found to be useful in describing family systems. They may also be predictive of children who will bully others or be victimized themselves. A sample of 20 bullies, 20 victims, 20 bully/victims, and 20 control children were selected from three middle schools via a system of peer nominations. These children then completed a version of the Family System Test (FAST) to establish how they perceived their families on the dimensions of Power and Cohesion. The four subgroups showed characteristic differences on the FAST plots, which are discussed. Future use of the FAST test in examining the link between perceived family structure and peer relationships seems warranted.     

Autonomic and behavioral evidence of "implicit" memory in amnesia

A profoundly amnesic patient with a left retrosplenial-fornix lesion was tested on a recognition task that evaluated both verbal and electrodermal aspects of new learning. In addition, "implicit memory" tasks (mirror reading and perceptual identification) were given. The patient displayed strong evidence of learning on all tasks although the results of this learning were not represented in explicit recall or recognition. These findings suggest that autonomic as well as behavioral evidence can index spared memory functions in amnesia. The specific meaning of electrodermal recognition and its possible place in the distinction between implicit and explicit memory is discussed.
