EFFECTS OF REINFORCEMENT FOR ALTERNATIVE BEHAVIOR DURING PUNISHMENT OF SELF-INJURY

A number of variables influence the effectiveness of punishment and may determine the extent to which less intrusive forms of punishment may be used as alternatives to more intrusive interventions. For example, it has been suggested that response suppression during punishment may be facilitated if reinforcement is concurrently available for an alternative response. However, results of basic research demonstrating this finding have not been replicated with interventions more commonly prescribed as treatments for problem behavior. We evaluated the effects of relatively benign punishment procedures (reprimands or brief manual restraint) on the self-injurious behavior of 4 individuals who had been diagnosed with mental retardation, when access to reinforcement for alternative behavior (manipulation of leisure materials) was and was not available. In all cases, punishment produced greater response suppression when reinforcement for an alternative response was available.     

A Practical Guide to the Comparative Case Study Method in Political Psychology

The case study, as a method of inquiry, is particularly suited to the field of political psychology. Yet there is little training in political science, and even less in psychology, on how to do case study research. Furthermore, misconceptions about case studies contribute to the methodological barrier that exists within and between the two parent disciplines. This paper reviews the various definitions and uses of case studies and integrates a number of recent insights and advances into a practical guide for conducting case study research. To this end, the paper discusses various stereotypes of the case study and offers specific steps aimed at addressing these criticisms.     

Loss of control over eating reflects eating disturbances and general psychopathology

This study examined the clinical significance of the loss of control over eating as a key component of eating disorders. It investigated the association of eating-related psychopathology and general psychopathology with objective bulimic episodes (OBEs; experiencing a loss of control while consuming large amounts of food) and subjective bulimic episodes (SBEs; experiencing a loss of control while consuming small/moderate amounts). A community sample of 81 women with a range of disordered eating was recruited: binge-eating disorder, bulimia nervosa, subclinical eating disturbances, or no eating disorders. They were interviewed using the Eating Disorder Examination and completed measures of eating-related and general psychopathology. Both OBE and SBE frequencies correlated significantly with measures of eating-related and general psychopathology, and no significant differences were found between the magnitudes of the correlations with either binge episode type. SBE frequency significantly and independently predicted global eating disorder psychopathology. The loss of control over eating, without consuming large amounts of food, was as closely associated with specific eating disorder psychopathology and general mental health as were traditionally defined OBEs. SBEs may be an important target of treatment and should be considered for future diagnostic classifications of eating disorders.     

On Associative Stigma: Implicit and Explicit Evaluations of a Mother of a Child with Autism Spectrum Disorder

Individuals with psychiatric problems are subjected to highly damaging stigma. Some research suggests that this stigma may extend to associates (e.g., family, friends), who themselves report being devalued, avoided, and rejected. The research literature on associative stigma is largely qualitative, and extant quantitative research has utilized only explicit measures which are notably weakened by self-presentational motives. In the current study, 95 undergraduates were randomized to hear one of two audio recorded vignettes pertaining to a fictional mother of a child with either autism spectrum disorder (ASD) or severe asthma. Participants then completed an Implicit Association Test capturing implicit evaluations of the fictional mother and two separate measures of explicit stigma. No group differences for either explicit measure emerged. However, the predicted group difference in implicit stigma emerged, such that the mother of the child with ASD was evaluated less positively than the mother of the child with severe asthma. Implicit-explicit correlations were not statistically significant but in the small to medium range according to effect size conventions. This study offers evidence of implicit associative stigma in the psychiatric domain. It also points to a variety of interesting avenues for further illumination of this potentially important phenomenon.     

On the generation and evaluation of inferences from single premises

A theory of how individuals construct mental models to draw inferences from single premises was tested in three experiments. Experiment 1 confirmed a counterintuitive prediction that it is easier to generate inferences between conditionals and disjunctions than it is to evaluate them. Experiment 2 replicated this finding, but an advantage found in the first experiment for conditional-to-disjunction over disjunction-to-conditional inferences was removed with different sentence contents. Experiment 3 showed that disjunction-to-conditional inferences were facilitated when premises expressed familiar indicative relations, whereas conditional-to-disjunction inferences were facilitated when premises expressed causal relations. The results indicate that small changes in task format can have large effects on the strategies that people use to represent and reason about different sentential connectives. We discuss the potential for theories other than mental models to account for these results. We argue that, despite the important role played by single-premise inferences in paraphrasing logical forms during inference, mental logic theories cannot account for the results reported here.     

Communicating Employability: the Role of Communicative Competence for Zimbabwean Highly Skilled Migrants in the UK

Skilled migration is an increasingly important topic for both policy and research internationally. OECD governments in particular are wrestling with tensions between their desire to use skilled migration to be on the winning side in the ‘global war for talent’ and their pandering to and/or attempts to outflank rising xenophobia. One aspect that has received relatively little attention is skilled migration from the African Commonwealth to the UK, a situation in which skilled migrants have relatively high levels of linguistic capital in the language of the host country. We focus here on the case of Zimbabwe. In spite of its popular image as a failed state, Zimbabwe has an exceptionally strong educational tradition and high levels of literacy and fluency in English. Drawing on 20 in-depth interviews of Zimbabwean highly skilled migrants, we explore the specific ways in which the communicative competences of these migrants with high formal levels of English operate in complex ways to shape their employability strategies and outcomes. We offer two main findings: first, that a dichotomy exists between their high level formal linguistic competence and their ability to communicate in less formal interactions, which challenges their employability, at least when they first move to the UK; and second, that they also lack, at least initially, the competence to narrativise their employability in ways that are culturally appropriate in England. Thus, to realise the full potential of their high levels of human capital, they need to learn how to communicate competently in a very different social and occupational milieu. Some have achieved this, but others continue to struggle.     

Stimulus similarity decrements in children's working memory span

Two experiments investigated the impact of the relationship between processing and storage stimuli on the working memory span task performance of children aged 7 and 9 years of age. In Experiment 1, two types of span task were administered (sentence span and operation span), and participants were required to recall either the products of the processing task (sentence-final word, arithmetic total) or a word or digit unrelated to the processing task. Experiment 2 contrasted sentence span and operation span combined with storage of either words or digits, in tasks in which the item to be remembered was not a direct product of the processing task in either condition. In both experiments, memory span was significantly greater when the items to be recalled belonged to a different stimulus category from the material that was processed, so that in sentence span tasks, number recall was superior to word recall, and in operation span tasks, word recall was superior to number recall. Explanations of these findings in terms of similarity-based interference and response competition in working memory are discussed.
