Visual Dominance in Amending the Directional Parameter of Feedforward Control

The authors examined visual dominance between trials in which the movement program was amended (i.e., off-line processing). Weighting between visual and proprioceptive feedback was examined in a trial-by-trial analysis of the directional parameter of feedforward control. Eight participants moved a cursor to a target displayed on a computer screen by manipulating a hand-held stylus on a digitizing tablet. In the first 30 trials, the cursor followed the stylus movement (practice condition). In the next 30 trials, the directional error of the stylus movement was presented in the opposite direction (reversal condition). Subjects knew the presence and the nature of the reversal. In the last 10 trials, the reversal was withdrawn (transfer condition). Directional error of feedforward control was relatively small in the practice condition, and it increased gradually in 1 of 2 directions as trials proceeded in the reversal condition. Positive aftereffect was observed in the transfer condition. A constant increment of the directional error indicated that both visual and proprioceptive feedback are registered, with higher weight on vision, and that weighting between those inputs is determined automatically or is fixed without any strategic control.     

Relative Effects of Three Knowledge of Results Treatments on Coincidence-Anticipation Performance

The relative effects of three knowledge of results (KR) treatments on performance of a complex coincidence-anticipation task requiring speed and accuracy were studied. Male volunteers (n=75) were assigned to one of three treatments: no KR, quantitative KR, or qualitative KR. No significant differences in the performance of treatment groups were found. It was suggested that the task itself may have provided enough information for fairly accurate performance.     

Experiences in running a staff group

This study examines an activating mechanism of aggressive behaviour in young children. Many studies on attachment theories have indicated disorganised attachment as a significant risk factor for externalising problems and have explained the aetiology of disorganised attachment in terms of deficits in affect, behaviour and cognitive functions from a traumatic or inconsistent environment. Via the moment-to-moment analysis of the play therapy process with a three-year-old, this paper attempts to identify how these emotional, behavioural and cognitive factors interact in actual situations and can lead to an observable behaviour: aggressive behaviour. The findings from this study indicate that the child with disorganised attachment was going through a dual process, one with her therapist and the other with her internalised caregivers. When anxiety and an ambiguous social cue from an unpredictable situation were added to the child's repetition of previous attachment experience, this ‘click’ lowered the threshold of regulation of affect, behaviour and cognition. The child turned to disorganised and aggressive behaviour, relying on her physiological signals regarding the perceived threat. Finally, this paper describes how these difficulties can be channelled by symbolic play via displacement and containment.     

Deviancy and Normative Training Processes in Experimental Groups of Delinquent and Nondelinquent Male Adolescents

The goal of this study was to identify the predictors and the moderators of group characteristics that influence deviancy and normative training processes in delinquent male adolescents. The authors experimentally tested the effects of group composition on deviant talk interaction processes among groups in which all members presented delinquent behaviors (“pure” delinquent group condition), those that included adolescents with no delinquent behaviors (“pure” normative group condition), and adolescents with both profiles (“mixed” group condition). Participants were 70 male adolescents aged 15–18 (M = 16.5; 56% Caucasian), with a random assignment to groups. Data were collected among three group sessions (T1, T2, T3), one session a week, using videotape. Two contents of interactions were also measured: antisocial and normative stories, counterbalanced across sessions. Results showed a significant group effect for antisocial talk and its reinforcement, with less antisocial talk within the mixed group condition in comparison to the pure delinquent group condition. The topic of interaction was also observed as a predictor of antisocial talk, with less normative interactions and more antisocial talk associated with antisocial topics. Finally, time moderated some relations between experimental groups and talk. We conclude with a discussion of the implications of this work for future research on deviancy training processes. Aggr.

Ethos and identity: Expressions and changes in the Israeli Jewish society

Abstract

A fundamental condition for the evolvement of any society is the development of social identity, which confers a sense of belonging and identification. The meaning of social identity is influenced by the ethos that members of a society share. The ethos consists of shared, central societal beliefs that give the society a dominant orientation and characterize it. The societal beliefs that underlie the ethos can change as a result of new, prolonged experiences of the society. Israeli society presents an example of such a process.

During the years of intractable conflict, Israeli society developed societal beliefs of a conflictive ethos that were conducive to successful coping with the conflictive situation. The ethos included beliefs about the justness of the Jews' goals, about security, and about delegitimising the Arabs, together with motifs of positive self-image, patriotism, unity, and peace. These beliefs characterised Israeli Jewish society and contributed meaning to the Israeli social identity. As the peace process developed, the societal beliefs of the conflictive ethos began to change, at least among part of the society members. But as the violent conflict re-erupted in fall 2000, the ethos of conflict is strengthening its standing in the society. The present paper describes the changes in the conflictive ethos with regard to each of the societal beliefs and discusses the implications of these changes for the meaning of the Israeli Jewish identity. Finally, general conclusions regarding the presented conception of social identity are outlined.     

A Practical development strategy: Logic and Reality

The purpose of the paper is to call the attention of general evolutionary theorists to a school of thought in economics that may be of help in their endeavour to discover new solutions to the social problems of our time. I argue that the so‐called Austrian school of economics shares with evolutionary theory an important insight into society. According to this insight, in society an evolutionary process is an ongoing phenomenon, in the course of which new innovations are continuously discovered. The particular outcomes of the discovery process are largely unpredictable because the information needed to make the innovations is dispersed and often tacit. In mainstream neoclassical economics evolution as a social phenomenon is as a rule ignored.     

Sorrow,shame, and self-esteem: Perception of self and others in groups for women survivors of child sexual abuse

Despite evidence that exists about the severity of impact of child sexual abuse (CSA), less has been published about treatment options. Much CSA is enshrouded in secrecy in the context of dysfunctional family dynamics, therefore group work is often recommended as a method of treatment. Although long- and short-term groups are seen as being equally effective, there are few published studies of long-term analytic groups for survivors of CSA. This study was designed to analyse the process of one long-term group. A case is made for using Core Conflictual Relationship Theme (CCRT), a method designed to analyse individual therapy, with reference to group theory. Shifts in self-perception and in relation to others are analysed from the beginning to the end of therapy.     

Strength of affective reaction as a signal to think carefully

Analytic processes reduce biases, but it is not known how or when these processes will be deployed. Based on an affective signal hypothesis, relatively strong affective reactions were expected to result in increased analytic processing and reduced bias in judgement. The valence and strength of affective reactions were manipulated through varying outcomes in a game or evaluative conditioning of a stimulus. Relatively strong positive or negative affective reactions resulted in less desirability bias. Bias reduction only occurred if participants had time to deploy analytic processes and indicators of the degree of analytic processing (in the form of attentional control) predicted less bias. Affective processes have long been acknowledged as a source of bias, but these findings suggest affective processes are also integral to bias reduction.     

Women–Focused Treatment Agencies and Process Improvement: Strategies to Increase Client Engagement

Behavioral health treatment agencies often struggle to keep clients engaged in treatment. Women clients often have additional factors such as family responsibilities, financial difficulties, or abuse histories that provide extra challenges to remaining in care. As part of a national initiative, four women-focused drug treatment agencies used process improvement to address treatment engagement. Interviews and focus groups with staff assessed the nature and extent of interventions. Women-focused drug treatment agencies selected relational-based interventions to engage clients in treatment and improved four-week treatment retention from 66% to 76%. Process improvement interventions in women-focused treatment may be useful to improve engagement.
