Fixed-interval punishment

The average rate of bar-pressing maintained by a variable-interval schedule of milk reinforcement in 33 rats was found to be a decreasing function of intensity of concurrent punishment and, over a wide range of shock intensities, was inversely related to punishment frequency. Cumulative records were, however, negatively accelerated during 30-min punishment sessions with complete suppression occurring earlier and earlier (after fewer and fewer shocks) as intensity increased. In addition, acceleration was often observed between successive fixed-interval shock presentations and, at low and moderate intensities, bursts of responding occurred after each shock. The time to recover between punishment sessions (post-punishment recovery) was an increasing monotonic function of punishment intensity.     

Endorsement of Group Change and Organization Change Affirmative Action Programs for Male and Female Beneficiaries

To test the position that some people’s willingness to endorse affirmative action is influenced by the match between beneficiary group and the attributional underpinnings of the programs, endorsement of four programs that could be used to benefit either women or men were assessed among 95 undergraduate students in Ontario, Canada. Students preferred the use of a remedial program that suggested that beneficiaries are under-qualified and need to develop job relevant skills for female versus male beneficiaries. This was driven by perceptions of the effectiveness of the program. For male beneficiaries, participants were more supportive of a mentorship development program that implied the necessity of structural change than they were of the remedial program. These effects were independent of participant gender.     

The influence of prior knowledge and repeated questioning on children's long-term retention of the details of a pediatric examination

Children's recall of the details of pediatric examinations was examined over the course of a 6-month interval. Although the 83 4- to 7-year-old participants reported a substantial amount of information at each assessment, performance declined over time, dropping sharply over the course of 3 months but then remaining constant out to the final interview at 6 months. As expected, older children provided more total information than younger children did and reported a greater proportion of the event components in response to general rather than specific questions. However, comparable patterns of remembering and forgetting over time were observed at each age level. In addition, no effects of repeated questioning--in the form of an interview at 3 months for half of the children--were observed on performance at the 6-month assessment. Moreover, children's prior knowledge about routine doctor visits was assessed before the checkup for half of the participants at each age and was associated with initial but not delayed recall. Although knowledge increased with age as expected, it nonetheless affected recall over and above the influence of age.     

Commitment to organizational change: extension of a three-component model

Three studies were conducted to test the application of a three-component model of workplace commitment (J. P. Meyer & N. J. Allen, 1991: J. P. Meyer & L. Herscovitch, 2001) in the context of employee commitment to organizational change. Study 1, conducted with 224 university students, provided preliminary evidence for the validity of newly developed Affective, Continuance, and Normative Commitment to Change Scales. Studies 2 and 3, conducted with hospital nurses (N = 157 and 108, respectively), provided further support for the validity of the three Commitment to Change Scales, and demonstrated that (a) commitment to a change is a better predictor of behavioral support for a change than is organizational commitment, (b) affective and normative commitment to a change are associated with higher levels of support than is continuance commitment, and (c) the components of commitment combine to predict behavior.     

Through their own eyes: a media-based group approach to adolescent trauma

This paper describes the process of two groups of students from high schools located in the immediate vicinity of the World Trade Center grappling to make sense of the events of September 11 through the creation of a documentary chronicling their experiences. The process of creating these videos mirrored the process and curative factors of a psychotherapy group in a non-stigmatizing, innovative, and accessible format, one generated by the students themselves with the assistance of professionals in the visual and performing arts. After reviewing the literature on the potential impact of violence on adolescents and the use of group treatment, especially in school settings, as an optimal choice for this population, we describe the distinctive process of the two separate groups of students, each culminating in different expressions of their very personal experience of September 11. We understand and contextualize their process through the lens of the therapeutic dynamics and elements of group work.     

Understanding the ‘blind spot’ when children move from foster care into adoption‡

Current social work practice in the UK dictates that when children move from foster care into adoption, the transition takes place within 7 and 14 days, and usually there is no contact between the child and their former carer for several months after the move, if at all. Very little attention or research has been aimed at understanding the rationale for these procedures, or their impact on the children. Joining forces with social work colleagues in a Looked After Children’s team, two child psychotherapists carried out a piece of qualitative research to look at these moves in more detail, and try to tease out how and why these key decisions are made. Analysing data from interviews with foster carers, adopters and social workers, the researchers found that the emotional experience of the child, particularly their experience of losing their foster carer, loses centre stage in people’s minds during this transition, leading to what is described as a ‘blind spot’ across the network. A significant reason for this emerged, in that the children tended to be very compliant both during and after the move and lacking in any obvious distress at losing their former carers, despite having previously been described as passionately attached to them. The research showed that adults across the network, all struggling with intense anxieties of their own, tended to interpret this as evidence that the children were ‘fine’ rather than questioning what might be going on at a deeper level. These research findings are explored in the light of a knowledge base accumulated from a working understanding of attachment and loss in early childhood, and of the psychoanalytical phenomena of individual and organisational defences against loss. Implications for future practice are suggested.
