Gender and developmental patterns of affect, belief, and behavior in simulated injury events

This study examined the hypothesis drawn from epidemiological data that beliefs and affective reactions of male second, fifth, and eighth graders, undergraduates, and adults in response to a series of four simulated bicycle collisions would show decreased expectation and avoidance of injury in comparison to females. This study also contrasted two additional hypotheses, one suggesting an invincibility belief in teenagers, producing a curvilinear age trend, with risky cognitions increasing from second grade, peaking at eighth grade, and then decreasing in adulthood. The other hypothesis suggested that with exposure, risky beliefs increased linearly, due to desensitization to cues of risk. As predicted, female participants did expect more fear and pain, and less exhilaration, and braked sooner after seeing the hazard than male participants. Linear rather than curvilinear age patterns emerged across films, revealing that the youngest participants anticipated more fear and less exhilaration than older participants. These results parallel developmental trends in which females and younger participants who anticipate more serious consequences are at lower risk for bicycle injury than are males, older children, and adolescents. Limitations of this analogue study and potential questions for both future research and the application of injury prevention techniques are explored.     

Deviant behaviors in rural elementary schoolchildren

A sample of 1567 third- and fourth-grade children in rural Illinois were rated on the Behavior Problem Checklist. The mean frequency of conduct problems, inadequacy-immaturity, personality problems, and socialized delinquency were analyzed by grade, sex, and age. Fourth graders and older children tended to have more problems than did third graders and younger children. Boys had more problems than did girls except on the personality-problem dimension.     

Do noise masks terminate target processing?

Much recent research in visual information processing has employed a methodology resting on the assumption that a noise mask following presentation of a target stimulus terminates processing of that target. In the absence of appropriate controls, such a methodology is viable only insofar as an erasure theory of masking is valid. However, the phenomena from which the erasure position has derived its strongest support have been subject to alternative theoretical explanations, the most general of which is that of temporal integration. The experiment reported here tested these alternatives. Twelve subjects served in a tachistoscopic study designed to determine whether the same noise field of dots could either erase a degraded target digit or facilitate target identification through temporal integration, under both forward and backward masking paradigms. This was found to be the case, and the results were interpreted as consistent with an integration theory of masking and as incompatible with an erasure conception. The results suggested that efforts to control target processing time through display of a visual noise pattern subsequent to target presentation are methodologically inadequate when devoid of some basic control operations.

Experience with songs in adulthood reduces song-induced gene expression in songbird auditory forebrain

Male songbirds learn to produce song within a limited phase early in life; however they continue to learn to recognize songs in adulthood. Studies looking at Zenk activation after exposure to songs learned early in life for song production and songs learned in adulthood show opposite patterns of activation, suggesting distinct neural mechanisms may be involved in these two forms of learning. In this study, we look at IEG Zenk activation in auditory regions NCM and CMM of song sparrows (Melospiza melodia) to see whether recent exposure to song in adulthood leads to greater or decreased Zenk activation upon hearing that song versus a novel song. We found significantly lower activation in birds exposed to previously heard songs versus novel songs in vNCM but not dNCM, though further analysis suggest an overall trend in NCM. We found no significant difference in the amount of activation to previously heard songs vs. novel songs in CMM. These results support previous findings suggesting that activation is reduced to learned stimuli; we discuss possible implications of these findings in relation to song production learning early in life and song recognition learning in adulthood.     

Learning symbolic-experiential therapy: One approach

This paper is intended to serve as a stimulus to the thinking of students regarding ways in which they might better organize their symbolic training experiences. It illustrates how one supervisee derived a conceptual framework from the literature that made it easier to track process events and organize her training experiences. The authors believe it is important to discover ways to facilitate the learning process without operationalizing the approach.director of training and research and professor of family therapy in the same department.
