Transfer in discrimination learning: Do children mediate more than adults?

A series of four-dimensional, discrimination-learning problems were presented to second-, sixth-, eighth-, and twelfth-grade students (ages 7, 11, 13, and 17 years, respectively). One pretraining problem, using different dimensions, preceded the four experimental problems; these employed identical dimensions and stimulus values. Solutions were selected without dimensional replacement.Blank-trial probes enabled detection of initial predictions. Results clearly indicated that (1) older subjects made dramatically fewer intradimensional predictions (utilizing the solution dimension from the preceding problem) than did younger subjects, (2) all age groups demonstrated systematic changes over problems; these reflected the specific solution sequence experienced, and (3) there were consistent developmental differences in the speed with which subjects noted and utilized regularities across problems.The pattern of data is not congruent with the expectations of mediation theory. However, it is in accord with the transfer hypothesis, which is a recent extension of hypothesis theory. The transfer hypothesis provides a theoretical framework which suggests when we should observe “mediational” behavior (i.e., intradimensional transfer) and when to expect the inverse.

Exploring links between polychronicity and well-being from the perspective of person–job fit: Does it matter if you prefer to do only one thing at a time?

This research examined polychronicity, which refers to an individual’s preference for working on many things simultaneously as opposed to one at a time. It was hypothesized that supplies–values fit on this temporal variable is related to well-being. Specifically, it was predicted that deficient and excess polychronicity supplies are associated with poorer well-being, and that well-being is uniformly high along the continuum of polychronicity fit. It was also hypothesized that fit effects are stronger for individuals who place high importance on how their time is allocated than for individuals who place low importance on that dimension. Participants in Study 1, a laboratory experiment, were students (N = 266); participants in Study 2, conducted in a field setting, were employees of Canadian organizations (N = 746). No fit effects were observed in Study 1. Consistent with the hypotheses, however, fit on the dimension of polychronicity was related to job satisfaction, self-efficacy, and psychological strain in Study 2. The role of value importance as a moderator of the relation between supplies–values fit and well-being was not supported.     

Psychological contract breach and job attitudes: A meta-analysis of age as a moderator

The aim of this study was to examine the influence of age in the relation between psychological contract breach and the development of job attitudes. Based on affective events, social exchange, and lifespan theory, we hypothesized that (1) psychological contract breach would be related negatively to job attitudes, and (2) that age would moderate these relations. The hypotheses were tested by means of a meta-analysis of k = 60 studies, using Weighted Least Squares estimation. Our results supported both hypotheses for the outcomes trust and organizational commitment. However, for job satisfaction the moderating influence of age was in the unexpected direction. The relations between contract breach and trust and organizational commitment were indeed stronger for younger workers, whereas the relation between contract breach and job satisfaction was stronger for older workers. The implications are discussed, and a research agenda is presented.     

Persons,animals, and identity

The paper is concerned with how neo-Lockean accounts of personal identity should respond to the challenge of animalist accounts. Neo-Lockean accounts that hold that persons can change bodies via brain transplants or cerebrum transplants are committed to the prima facie counterintuitive denial that a person is an (biologically individuated) animal. This counterintuitiveness can be defused by holding that a person is biological animal (on neo-Lockean views) if the “is” is the “is” of constitution rather than the “is” of identity, and that a person is identical with an animal in a sense of “animal” different from that which requires the persistence conditions of animals to be biological. Another challenge is the “too many minds problem”: if persons and their coincident biological animals share the same physical properties, and mental properties supervene on physical properties, the biological animal will share the mental properties of the person, and so should itself be a person. The response to this invokes a distinction between “thin” properties, which are shared by coincident entities, and “thick” properties which are not so shared. Mental properties, and their physical realizers, are thick, not thin, so are not properties persons share with their bodies or biological animals. The paper rebuts the objection that neo-Lockean accounts cannot explain how persons can have physical properties. To meet a further problem it is argued that the biological properties of persons and those of biological animals are different because of differences in their causal profiles.     

The Psychological Citizen and the Two Concepts of Social Contract: A Preliminary Analysis

A shift in focus from the logical to the psychological social contract allows us to better explore the socialization of the psychological citizen, and the relationship between identity of individuals and the socio‐political order, with its particular group‐based inequalities. Traditional psychological studies have provided valuable insights into certain aspects of identity, but the new narrative research is leading to novel insights into longer term processes associated with the positioning of identity. The new approach recognizes the dual nature of mental processes and the integral role of context in individual development. Illustrative examples are discussed of the role of cultural carriers in the formation of identity, highlighting the infusion of the macrolevel normative system to thought and action at the microlevel of individuals.     

The relation between essentialist beliefs and evolutionary reasoning

Historians of science have pointed to essentialist beliefs about species as major impediments to the discovery of natural selection. The present study investigated whether such beliefs are impediments to learning this concept as well. Participants (43 children aged 4–9 and 34 adults) were asked to judge the variability of various behavioral and anatomical properties across different members of the same species. Adults who accepted within-species variation—both actual and potential—were significantly more likely to demonstrate a selection-based understanding of evolution than adults who denied within-species variation. The latter demonstrated an alternative, incorrect understanding of evolution and produced response patterns that were both quantitatively and qualitatively similar to those produced by preschool-aged children. Overall, it is argued that psychological essentialism, although a useful bias for drawing species-wide inductions, leads individuals to devalue within-species variation and, consequently, to fail to understand natural selection.     

How Cognitive Behavioural,Rational Emotive Behavioural or Multimodal Coaching could Prevent Mental Health Problems,Enhance Performance and Reduce Work Related Stress

This case study describes the therapeutic work with a client suffering from depression. A cognitive approach was used and a brief summary of the problem and the therapy is outlined. The client had suffered from procrastination for a long time and this was one of the key areas to be addressed in therapy. This case is presented to highlight that cognitive behavioural, rational emotive behavioural or multimodal coaching may be able to prevent mental health problems. It is possible that the client’s problem with procrastination could have been tackled in psychologically based coaching at an earlier stage. Psychological coaching could have provided the client with tools to deal with the procrastination and increase her self-awareness. This could have prevented the development of the depression or helped the client to intervene at an earlier stage.

The Influence of Clinical Variables on the Psychological Adaptation of Adolescents after Solid Organ Transplantation

This study assessed the influence of clinical and socio-demographic variables on the psychological adaptation of transplanted adolescents. Twenty-six transplanted adolescents and 25 healthy adolescents, aged 13–17, and their parents participated in the study. The following domains were measured: social competence, emotional/behavioral problems, self-concept, self-esteem and subjective well-being. The findings revealed that transplanted boys presented significantly less social competence (U = 26,000, p < .05) and more externalizing problems (U = 25,000, p < .05), social problems (U = 25,000, p < .05) and attention problems (U = 17,500, p < .01) than healthy boys. In contrast, transplanted girls displayed significantly more internalizing problems (U = 47,000, p < .05) and lower physical self-concept (U = 49,500, p < .05) than healthy girls. Hierarchical regression analysis showed clinical variables, especially waiting-list time, significantly predicted attention problems (β = .364, p < .05) and negative affect (β = .632, p < .05) in transplanted adolescents. Also, male (β = −0.554, p < .01) and younger (β = −0.444, p < .01) transplanted adolescents were at risk for attention problems. Our data suggest the importance of the waiting-list time for transplanted adolescents. Efforts to reduce the pretransplant phase would help adolescents achieve better psychological adaptation at long-term posttransplant.
