Concurrent-schedule performance in transition: changeover delays and signaled reinforcer ratios

Six pigeons were trained in experimental sessions that arranged six or seven components with various concurrent-schedule reinforcer ratios associated with each. The order of the components was determined randomly without replacement. Components lasted until the pigeons had received 10 reinforcers, and were separated by 10-s blackout periods. The component reinforcer ratios arranged in most conditions were 27:1, 9:1, 3:1, 1:1, 1:3, 1:9 and 1:27; in others, there were only six components, three of 27:1 and three of 1:27. In some conditions, each reinforcement ratio was signaled by a different red-yellow flash frequency, with the frequency perfectly correlated with the reinforcer ratio. Additionally, a changeover delay was arranged in some conditions, and no changeover delay in others. When component reinforcer ratios were signaled, sensitivity to reinforcement values increased from around 0.40 before the first reinforcer in a component to around 0.80 before the 10th reinforcer. When reinforcer ratios were not signaled, sensitivities typically increased from zero to around 0.40. Sensitivity to reinforcement was around 0.20 lower in no-changeover-delay conditions than in changeover-delay conditions, but increased in the former after exposure to changeover delays. Local analyses showed that preference was extreme towards the reinforced alternative for the first 25 s after reinforcement in changeover-delay conditions regardless of whether components were signaled or not. In no-changeover-delay conditions, preference following reinforcers was either absent, or, following exposure to changeover delays, small. Reinforcers have both local and long-term effects on preference. The former, but not the latter, is strongly affected by the presence of a changeover delay. Stimulus control may be more closely associated with longer-term, more molar, reinforcer effects.     

The Props are Falling Down and We Want to Make Music: A Narrative Perspective on Organisations in Transition (Violins/Violence in Organisations)

While South African society finds itself in the throes of political changes, therapists working within organisations in transition find themselves challenged by the turbulence of transformation. The authors are a group of therapists attempting to understand, from a narrative perspective, the organisational context within which they work. This paper recounts the processes around the design, implementation, and outcomes of a workshop on this theme. The main body of the paper consists of a letter that was sent to participants after the workshop. The reader is invited to join collaboratively in our reflections so as to continue an open-ended, creative process.     

Political Power and Race Relations in South Africa: African Attitudes Before and After the Transition

When an oppressed majority finally gains political power, what happens to its attitudes to its erstwhile oppressor, and to its perceptions and feelings about its socioeconomic disadvantages that were established during its oppression? Longitudinal data from pre- and post-transition surveys of black South African college and high school students indicate marked reductions in perceptions of and outrage about intergroup socioeconomic inequity and deprivation relative to English-speaking and Afrikaans-speaking whites, but no change in attitudes toward these groups or toward whites in general. The findings are discussed in terms of contemporary theory and research on justice, intergroup relations, and group conflict. Some tentative implications for the prospects for a democratic political culture in South Africa are noted.     

Career mapping for international students: A critical-constructivist approach

Despite rapidly increasing presence of international students seeking career guidance and opportunities in the United States, existing counseling literature offers limited perspectives on how counselors can support this community using strengths-based and culturally responsive approaches. Addressing this long-standing gap, we offer this conceptual scholarship discussing career mapping as a dialogical and critical-constructivist strategy for career counselors to help international students understand their life story, strengths, and barriers in the context of career development, and plan their actions accordingly. Implications for practice are also offered.     

Boundaries for career success? How work–home integration and perceived supervisor expectation affect careers

The necessity to actively manage the work–home boundaries has drastically increased. We postulate that work–home integration may affect individuals' subjective career success via its positive effects on work goal attainment and exhaustion. Furthermore, we study perceived supervisor expectation for employee work–home integration as a boundary condition. Our three-wave online survey with 371 employees showed support for the two hypothesized moderated mediation effects. Work–home integration preference is indirectly related to subjective career success: (1) positively via home-to-work transitions and work goal attainment and (2) negatively via home-to-work transitions and exhaustion. Perceived supervisor expectation constrained work–home integration preference's direct effect on home-to-work transitions and indirect effects on subjective career success. Exploratory analysis revealed that exhaustion negatively affected all career success dimensions, whereas work goal attainment was only related to some. Our results indicate that supervisor expectation can override the effect of employee's work–home integration preference on home-to-work transitions which have a double-edged sword effect on subjective career success. Our study contributes to integrating the careers and work–life interface literature and incorporating contextual factors. Furthermore, with the exploration of differential effects on subjective career success, we advance our understanding of this outcome's nomological network.     

Un éclairage de la transition de retraite par l’analyse interprétative phénoménologique (IPA)

IntroductionInterpretative phenomenological analysis (IPA) is a method of qualitative discourse analysis that aims to understand lived experience and the meaning that individuals attribute to it.ObjectivesAfter describing its theoretical foundations and its methodology, this paper applies this method on a research on the experience of retirement transition which collected 28 interviews. It thus aims to show the interest of this method in understanding the psychological and reflexive processes inherent in periods of life marked by transformations.MethodCentred on the way in which people imagine their own transformation of identity at retirement age and on the meaning they give to it, the analysis takes into account the adjustments made to daily life, to the relationship with time, and to social relations. This analysis is based on the detailed study of a case, and then compared to five other cases.ResultsThe need to make a break, manifested by the extent and form of the transformations given on a daily basis, varies according to the subjects, meaning being attributed not only to the break but also to continuity. A temporal experience marked by a present to be reconfigured and interpersonal relationships deemed meaningful, is, on the other hand, very shared.ConclusionBy bringing to light the psychological and reflexive processes of the experience of retirement, this study carried out with reference to the IPA can contribute to nourishing the practices of support for retirement, which are tending to develop.     

Organic self-talk content categories and their relations to sport-specific contextual and personal factors

While strategic self-talk interventions are well documented, less is known regarding organically occurring self-talk. Previously, eight organic self-talk content categories were identified, however contextual and personal factors relating to these categories is unexplored. The aim of the study was to explore the relationships between stress, coping, athletic identity, demographic and sport-related factors and the eight organic self-talk categories of anxiety control, confidence, disengagement, instruction, psych-up, somatic fatigue, worry, and irrelevant. 216 NCAA student-athletes were recruited. Regression was used to determine the relationships between the contextual and personal variables and organic self-talk. Stress, coping and self-talk categories were compared in and out-of-season. Stress was associated with all self-talk frequencies except confidence. Coping was associated with psych-up, confidence and worry. Athletic identity was associated with psych-up, confidence, instruction and disengagement. Age was associated with anxiety control and instruction. Lastly, sport type and division level were associated with disengagement and instruction self-talk respectively.     

Role adjustment as the unit of analysis for researching child development during the transition to school

While child development is well-recognized as a complex process which could hardly be decomposed into separate lines or domains in contemporary psychological theories, the decomposition approach is widely used in empirical studies. Based on the cultural-historical theory, this study argues for adopting the unit of analysis as a way to bridge this gap, and finds “role adjustment” as a suitable unit to analyse child development during the transition to school. The case of a 5-year-old second-generation Chinese Australian child's transition to school (with a total of 34 h of observation and 5 h of interview) is presented to verify its feasibility and to illustrate how it could be achieved in a research practice. The case study demonstrates that a child's role adjustment is in essence a process of transforming his/her role system, during which his/her major roles, the relation of the major roles, as well as his/her role-taking patterns change as a whole, and by tracing a child's role adjustment trajectory, how the child is learning and developing, what difficulties he/she encounter, and why these difficulties appear become clear.     

Are older adults in Hong Kong “living in history” in their autobiographical memories?

Transition theory posits that autobiographical memories are organized by major life transitions, which is often supported by the Living-in-History effect that occurs when people frequently refer to public events to support their date estimates of personal events. In the present study, 52 Chinese older adults in Hong Kong recalled autobiographical events using cue-word method and justified the date estimates of the events. They also reported the most important events and assessed their impacts. Results showed that participants referred to public events only when estimating the date of 5.5% of word-cued events and reported a few public events as personally important, suggesting an absence of the Living-in-History effect. Nonetheless, word-cued events and important events accumulated around major life transitions to form a transition bump; the material change that important events brought about predicted whether the important events were used to organize autobiographical memory, thereby providing new evidence for the transition theory.
