The functions of nonsuicidal self-injury: support for cognitive-affective regulation and opponent processes from a novel psychophysiological paradigm

Although research on the reasons for engaging in nonsuicidal self-injury (NSSI) has increased dramatically in the last few years, there are still many aspects of this pernicious behavior that are not well understood. The purpose of this study was to address these gaps in the literature, with a particular focus on investigating whether NSSI (a) regulates affective valence in addition to affective arousal and (b) serves a cognitive regulation function in addition to an affect regulation function. To elucidate these issues, the present study utilized a sample of 112 participants (33 controls, 39 no pain controls, 16 NSSI individuals, and 24 controls matching the affect dysregulation levels of the NSSI group), employed psychophysiological measures of affective valence (startle-alone reactivity) and quality of information processing (prepulse inhibition), and used experimental methods involving an NSSI-proxy to model the NSSI process. Results largely were consistent with predictions, supporting the hypotheses that NSSI serves to regulate cognitive processing and affective valence. On this latter point, however, the control groups also showed a decrease in negative affective valence after the NSSI-proxy. This unexpected finding is consistent with the hypothesis that opponent processes may contribute to the development of self-injurious behaviors (Joiner, 2005). Overall, the present study represents an important extension of previous laboratory NSSI studies and provides a fertile foundation for future studies aimed at understanding why people engage in NSSI.     

Further examination of discriminated functional communication

One child with developmental disabilities was taught to mand for attention by saying "excuse me." Treatment effects were extended to multiple training contexts by teaching the participant to attend to naturally occurring discriminative stimuli through differential reinforcement of communication during periods of the experimenter's nonbusy activities (e.g., reading a magazine). Results are discussed in terms of future research on the generalization and maintenance of functional communication in the natural environment.     

USING COMPLEX AUDITORY—VISUAL SAMPLES TO PRODUCE EMERGENT RELATIONS IN CHILDREN WITH AUTISM

Six participants with autism learned conditional relations between complex auditory‐visual sample stimuli (dictated words and pictures) and simple visual comparisons (printed words) using matching‐to‐sample training procedures. Pre‐ and posttests examined potential stimulus control by each element of the complex sample when presented individually and emergence of additional conditional relations and oral labeling. Tests revealed class‐consistent performance for all participants following training.     

Shooting Genes,Distributing Credit: Narrating the Development of the Biolistic Gene Gun

Using oral histories with scientists, technology transfer managers and other collaborators who were involved with the development of the biolistic gene gun, I investigate how actors narrate their experiences of technology transfer. The individuals who worked on the gene gun draw on two different interpretive repertoires for describing the innovation process: a ‘localized’ repertoire that highlights defined moments and the conceptual contributions of a few individuals; and a ‘distributed’ repertoire that emphasizes longer time frames, the process of technical implementation and the importance of a network of collaborators. Each of these repertoires identifies a different assemblage of actors as deserving of credit and reward for the development of the gene gun. Examining how scientists employ these modes of describing the innovation process offers a way of thinking about how university inventors negotiate tensions around novel features of academic capitalism, such as personal profit arising from the commercialization of university technologies.     

Dynamic (Kinesthetic) Touch Perception in Preschool Children

The preschool years are an important time during which children gain proficiency using the hands for both performatory and perceptual functions that involve dynamic (kinesthetic) touch. We evaluated dynamic touch perception of object extent and found that preschool children are able to discriminate length by dynamic touch early, but perception is not very fine-tuned and perceptual attunement to inertial characteristics increased with age. An analysis comparing the performatory and perceptual functions of the hands showed links between performance and perception in dynamic touch tasks that did not require haptic–visual correspondence. We concluded that whereas dynamic touch is functional early in the preschool years, perceptual acuity is not very precise and haptic–visual correspondence remains immature. In addition, reliance on inertial properties as information to make judgments of length emerges between 3 and 5 years and attunement to inertial properties likely continues to develop throughout childhood because perceptual judgments of 5-year-olds did not reach adult levels. Tight links between the performatory and the perceptual functions of the hand suggest this is an important avenue for future research.     

Action Perception and Outcome Valence: Effects on Children's Inferences of Intentionality and Moral and Liking Judgments

The influences of different action-outcome scenarios on children's evaluative judgments and inferences of outcome intentionality were assessed. One hundred forty-five kindergartners, 2nd graders, and 4th graders heard 4 stories about child actors who engaged in 1 action or 3 equifinal actions and caused a positive or negative outcome. The stories made no mention of the actors' anticipated outcome so that we could assess the children's inferences of whether the actors wanted and had tried to cause the outcome. Children also rated their liking for the actors and the actors' morality. Children's moral and liking judgments were not significantly differentiated by action condition. However, actors who caused positive outcomes received favorable liking and moral judgments, and actors who caused negative outcomes received neutral liking and moral judgments. Children's intentionality inferences varied by the actors' actions and were moderated by outcome valence. The authors discuss children's apparent use of the valence rule when inferring intentionality and their reluctance to judge harshly actors who cause negative outcomes when not privy to the actors' intentions.     

The Roles of Explanation and Feedback in False Belief Understanding: A Microgenetic Analysis

The authors examined effects of feedback and explanation on false belief performance. Thirty-three children (42–54 months; 15 girls, 18 boys) were randomly assigned to four treatment conditions: explanation, feedback, feedback researcher explains, and feedback child explains. Children completed false belief tasks during pretraining, 8 training sessions, and posttraining across 6 weeks. Language comprehension was assessed at pretraining. The authors hypothesized that children would improve most when training involved feedback and explanation. Generalized estimating equations modeling was used to analyze the data. Children who received feedback and generated explanations for characters’ false beliefs improved across training sessions more so than children in other conditions. Children's explanations for false beliefs also were explored. Implications of the findings are discussed.     

Normal/Deserving Citizens and the Transabled Other: A Sociological Analysis of Online Commenters Reactions to Transability

ABSTRACT

In this paper, the authors explore the ways that online commenters on the National Post’s website articulate their opinions, understandings, and feelings about a news story on the topic of transability. By conducting a content analysis of the online data, the authors examine how the commenters demonstrate that dominant forms of power, knowledge, and discourse permeate common-sense understandings of the healthy, normal citizen through their acting incredulous towards, pathologizing, shaming, and sometimes reacting violently towards transabled people.     

examining the role of differential association and techniques of neutralization in explaining corporate crime

A limited number of studies have examined white-collar offending decision making patterns and virtually none have focused on testing Differential Association or Techniques of Neutralization theory in particular. This study evaluates the offending decisions of MBA students to commit corporate offending in the promotion/sales of a hypothetical pharmaceutical drug. The sample consisted of 133 MBA students enrolled at a university in the United States. Findings supported predictions that anticipated agreement of coworkers and the board of directors would be positively associated with decisions to further market and produce a hypothetical drug that was about to be recalled by the Food and Drug Administration. However, results also showed that the decision to commit corporate crime was inversely related to perceptions that close friends and business professors agree with the decision, which went against predictions based on differential association theory. Several neutralizing techniques—especially the beliefs that government exaggerates dangers to the consumer and profit is the most important priority—predicted the decision to further market the drug. Subsequent analyses showed that older respondents were more likely to employ techniques of neutralization in decisions to commit corporate crime, especially techniques relating to profits. Future research directions are outlined.
