Recent advances in operant conditioning technology: a versatile and affordable computerized touchscreen system.

We report the construction of a new operant chamber that incorporates modern computer, touchscreen, and display technologies. An LCD display was housed in the front wall of a lightweight Plexiglas chamber. An Apple eMac computer was used to present visual stimuli on the monitor and to control other chamber events. Responses to the stimuli were recorded using a transparent resistive-type touchscreen that overlaid the monitor. The resulting system is simple and inexpensive to construct but powerful and flexible enough to explore a broad range of issues in animal learning and behavior.     

Expressed emotion in families of children and adults with intellectual disabilities

Expressed emotion (EE) is a measure of the affective relationship between two people characterized by criticism, hostility, and emotionally over-involved attitudes. Outside of the field of intellectual disabilities, there has been considerable interest in EE as an environmental marker that explains variance in the severity and/or course of a number of psychiatric disorders. Researchers have also studied EE in parents and found strong associations with children's behavior problems. In this review, we focus on the data from 11 published studies of EE in families of children and adults with intellectual disabilities. We conclude that there is evidence for the presence of high EE in some families, and that this alone should concern researchers and clinicians and set an agenda for considerable future research effort. We also note a lack of attention to the measurement of EE in intellectual disability. In terms of the existing evidence base, we suggest that there is support for the hypothesis that behavior problems in children and adults with intellectual disabilities may be related to high EE in parents, and a small amount of data predicting over time support the putative causal effect of high EE on maintaining or exacerbating behavior problems. Given that EE is perhaps best conceptualized as the result of an interaction between caregivers and those cared for, there is a need to explore interventions that may help to remediate high EE within families. It is also important to understand from this position that EE may be a normative part of the experience of caring for someone under very stressful circumstances and not something for which families are blamed. Other future research priorities and some implications for practice are also discussed.     

Opposition from Christians to Myers–Briggs personality typing: an analysis and evaluation

Myers–Briggs personality typing is widely used in the Christian church as an aid to individual self‐understanding and spiritual formation. However, some Christian leaders have expressed doubt about its validity in understanding human personality and also opposition to its use in nurturing spiritual growth. The aim of the work reported was to identify and examine the reasons for this negative stance towards personality typing. It was achieved by content analysis of published writings and, in a few cases, by correspondence with persons known to have a critical stance. The analysis showed five principal areas of concern: misuse of personality typing in spiritual formation; personality typing as a simplistic analysis; personality typing as a restrictive pigeon‐holing; unethical use of personality typing; and the Jungian derivation of personality type theory. Evaluation of this unease reveals significant semantic and epistemological issues and also a concern that personality typing, while not denying the tenets of Christian belief, could rival them for primacy in the hearts and minds of Christians.     

The Relevant Equivalence Property

The pure implicational and the multiplicative fragments of arange of propositional relevant (and other) logics are shownto have the property that any two formulas equivalent in sucha logic are constructed from exactly the same propositionalvariables – as opposed to merely having (as the definitionof relevance itself would require) some propositional variablein common.     

The Interactive Effects of Procedural Justice and Equity Sensitivity in Predicting Responses to Psychological Contract Breach: An Interactionist Perspective

Purpose  The purpose of the study was to examine the combined interactive effects of a situational variable (procedural justice) and a dispositional (equity sensitivity) variable on the relationship between breach and employee outcomes. Design/methodology/approach   Data were obtained from 403 full-time employees representing a wide variety of business sectors in the Philippines. Supervisors were requested to provide an assessment of their subordinate’s civic virtue behavior. Findings  Results showed that equity sensitivity and breach interacted in predicting affective commitment. The negative relationship between breach and affective commitment was stronger for employees with an input-focused approach to organizational relationships (referred to as benevolents) than for those with an outcome-focused approach (referred to as entitleds). Results also indicated a stronger negative relationship between contract breach and civic virtue behavior under conditions of high procedural justice. Finally, a three-way interaction was found between contract breach, procedural justice and equity sensitivity in predicting affective commitment. Implications  Our findings provide a new insight suggesting that worse outcomes are to be anticipated especially if employees have an expectation that procedural justice can prevent any form of contract breach. In addition, although previous research has portrayed benevolents as more accepting of situations of u under-reward, this study has demonstrated that they too have their limits or threshold for under-reward situations. Originality/value  This research suggests that the type and intensity of one’s reactions to psychological contract breach is influenced by interactive forces of the individual’s disposition and the organizational procedures. A portion of this paper was presented at the 64th annual meeting of the academy of management meeting, New Orleans, USA, August, 2004.     

Paniksyndrom

According to an ecologically oriented model, a panic syndrome may occur when a patient is blocking an impending and already initiated development in shaping his/her relational niche. Unconsciously he/she may constellate an outer relationship situation, that demands a previous avoided change in relationships, which can be utilized by therapy.
