Motivating Operations Affect Stimulus Control: A Largely Overlooked Phenomenon in Discrimination Learning

Several recent studies have explored what Michael (e.g., 1982) termed the value-altering effect and the behavior-altering effect of motivating operations. One aspect of the behavior-altering effect that has garnered no recent attention involves changes in stimulus control produced by motivating operations. To call attention to this aspect of the behavior-altering effect, we herein review 11 studies that are concerned with the influence of varying levels of food or water deprivation on stimulus generalization. These studies suggest that motivating operations influence stimulus control (a) by changing the evocative strength of not just an established discriminative stimulus, but also of stimuli that are physically similar to it; (b) by changing the range of stimuli that evoke the operant in question; and (c) by exerting these effects in a graded fashion. These findings are potentially of conceptual and applied significance, and it appears that further research examining how motivating operations alter stimulus control, including some studies suggested herein, is warranted.     

The relative importance of psychopathy-related traits in predicting impersonal sex and hostile masculinity

This paper reports the relative contributions of several facets of subclinical psychopathy (i.e., callous affect, erratic lifestyle, interpersonal manipulation), subclinical narcissism (i.e., entitlement, exploitation), and trait aggression (i.e., anger) to the prediction of four enduring attitudes towards women and sexual assault (i.e., hostility towards women, negative attitudes regarding women, sexual dominance, impersonal sex) and a behavioral indicator of an impersonal sexual behavior (i.e., number of one-night stands). Survey data were collected from 470 single men living in the Detroit Metropolitan area. The importance of personality traits varied as a function of the outcome with anger most predictive of hostility toward women; erratic lifestyle most predictive of impersonal sexual attitudes and behavior, and entitlement most predictive of sexual dominance and negative attitudes toward women. These outcome-specific findings are interpreted and directions for future research are discussed.     

Development and validation of a measure of perceived relative deprivation in childhood

Childhood adversity is known to impact psychological functioning and physical health in later life, but research into the mechanisms responsible has been impeded by the absence of a suitable retrospective measure of perceived relative deprivation in childhood. We developed and validated scores of the Perceived Inequality in Childhood Scale (PICS). In total, 683 students from Liverpool University, Liverpool Hope University and the University of East London were sampled by means of online methods. The data were separated using odd–even methods and an exploratory factor analysis identified a 2 factor solution: perceived relative deprivation (12 items) and family social capital (4 items). The measure was then subjected to confirmatory factor analysis and a 3 factor structure was revealed. The scale was further validated against Index of Multiple Deprivation (IMD) scores of childhood addresses. The PICS is a brief, practical scale suitable for both small and large-scale research studies.     

Night Shift Working Mothers: Mutual Perceptions with Adolescent Children

The study investigated the mutual perception of relationships between mothers with day and night shift work and their teenage children. A cross-sectional survey using purposeful sampling was used. Two groups of 35 mothers and their adolescent children completed a Parent-Adolescent Relationship-Questionnaire (Robin, Koepke, Moye & Gerhardstein, 2009). Data was analysed by means of SAS and SPSS programmes. Findings show that adolescent children of day shift working mothers perceive communication and problem solving with their mothers as more efficient than adolescent children of night shift working mothers. Global Distress was lower in day shift mothers and their children. Night shirt work lowers the perceived quality of parenting.     

Assessment of the Barnum Effect in Computer-Based Test Interpretations

A prototypic experiment for validating computer-based test interpretations (CBTIs) was conducted. Undergraduates (N = 63) completed the Comprehensive Personality Profile Compatibility Questionnaire (CPPCQ; Craft, 1987). One treatment group rated real CBTIs for relative accuracy, and another group rated bogus CBTIs. A significant main effect for differences in ratings indicated that the real CPPCQ profiles were rated as 74.5% accurate whereas the bogus CBTIs were rated as 57.9% accurate. Several covariate effects were tested, but none were significant.     

The rehabilitation of primary object relations in the first year of intensive therapy with a severely deprived child

The following is an account of the first year of a therapy carried out in the public sector of a child born at the beginning of 1990 in an eastern European country and brought up in a home for abandoned children until he was placed with Italian parents at the end of 1995. I shall describe the child's initial psychological state, vigorous, but desperate, and then go on to describe the course of the first year of therapy, focusing in particular on the sessions of the from period, in which, apart from the quality and intensity of his anxiety, his need to fie this anxiety by retracing the stages of his first object experiences is clear.     

Child psychotherapy then and now

The following is the text of an introductory presentation given on the occasion of the 40th Birthday Conference of the Journal of Child Psychotherapy. It provides an historical overview of the Journal's development, and in particular compares and contrasts the first two issues of the Journal with the two most recent. The importance of research is emphasised.     

Ultralarge lotteries: Analyzing the Lottery Paradox using non-standard analysis

A popular way to relate probabilistic information to binary rational beliefs is the Lockean Thesis, which is usually formalized in terms of thresholds. This approach seems far from satisfactory: the value of the thresholds is not well-specified and the Lottery Paradox shows that the model violates the Conjunction Principle. We argue that the Lottery Paradox is a symptom of a more fundamental and general problem, shared by all threshold-models that attempt to put an exact border on something that is intrinsically vague. We propose application of the language of relative analysis—a type of non-standard analysis—to formulate a new model for rational belief, called Stratified Belief. This contextualist model seems well-suited to deal with a concept of beliefs based on probabilities ‘sufficiently close to unity’ and satisfies a moderately weakened form of the Conjunction Principle. We also propose an adaptation of the model that is able to deal with beliefs that are less firm than ‘almost certainty’. The adapted version is also of interest for the epistemicist account of vagueness.     

Cognitive-behavioural Analysis and 1 reatment ot Insomnia

Abstract

Insomnia is a condition characterized by subjective complaints of insufficient sleep and poor daytime functioning. Objective measures of sleep and daytime functioning, however, seldom show evidence of a similar degree of dysfunction. Most insomniacs, for example, do not suffer from sleep deprivation or daytime sleepiness. This discrepancy between subjective and objective measures of sleep and daytime functioning suggests that cognitive factors may play a central role in persistent insomnia. In particular, it is argued that fears about insufficient sleep and its adverse daytime consequences tend to interfere with sleep, thereby causing a vicious cycle which serves to maintain the insomnia. It is also argued that perfectionist standards and other dysfunctional beliefs may predispose people to these kinds of fears. Finally, existing models for cognitive-behavioural treatment of insomnia are criticized for being almost exclusively focused on the night-time aspects of insomnia. If insomnia is maintained by various kinds of vicious cycles involving fears, beliefs, and standards with regard to daytime functioning, these daytime aspects of insomnia should receive more attention in cognitive-behavioural treatment.
