Reinforcement and the organisation of behaviour in golden hamsters: Differential overshadowing of a CS by different responses

Are different responses differentially associable with their consequences? An overshadowing design was used to try to answer this question for three responses previously studied in golden hamsters. In Experiment I, scrabbling was rapidly suppressed by electric shock punishment, and it overshadowed a tone which occurred between scrabbling and shock. In Experiment II, no evidence of response-shock association was obtained when open rearing was the punished response, and open rearing did not overshadow the tone. Punishment had some effect on face washing, but there was no statistically significant overshadowing with this response. These results are consistent with the idea that differences in punishment suppression among these three responses have an associative basis. They also demonstrate the usefulness of a novel paradigm for studying “preparedness” of response-reinforcer associations.     

The Tichborne Claimant: Person identification following very long intervals

An account is given of the nineteenth-century case of the Tichborne Claimant, in which someone purporting to be Sir Roger Tichborne, a missing heir, arrived in England from Australia 13 years after Sir Roger had been assumed drowned at sea. Many people, including Lady Tichborne, Sir Roger's mother, positively identified him. Others insisted that he was an impostor. A civil court and a criminal trial each found against The Claimant for various reasons, but the question of The Claimant's true identity remains open to this day. The case of the Tichborne Claimant is used to illustrate issues in identification that are of contemporary interest. The particular matter of how faces change over time is briefly discussed.     

The Personal and Social Worries of Adolescents in Northern Ireland: Results of a Survey

The aim of this study was to ascertain the self-perceived social and personal concerns of adolescents attending educational institutions in Northern Ireland. 446 questionnaires from 15-18-year-old students at ten institutions were analysed in order to determine the frequency with which respondents reported worrying about the following broad areas: school, choosing a job, finding a job, home, starting work, opposite-sex relationships, personal issues, and relating to others. The effects of variables such as gender, age and nature of educational institution attended were also examined. The results indicated that most frequent worry was reported about finding and choosing employment, personal issues and opposite-sex relationships. Gender, age and religious affiliation of school attended exerted major effects. Implications for those involved in working with adolescents within educational contexts are discussed.     

Challenging occupational stereotypes: Women's training roadshows and guidance at school level

The views that women and girls hold about themselves contribute to the segregation of women in the labour market. Women's Training Roadshows are an example of initiatives aimed at 'cultural interruption', in that they attempt to challenge occupational stereotypes. This paper evaluates the Cardiff Women's Roadshow from the schoolgirls' perspective and discusses the implications of the findings for careers guidance at school level.     

Countering perfectionism in research on clinical practice I: Surveying rationality changes after a single intensive ret intervention

The failure of controlled experimental research on therapy out-come to produce findings of clinical as well as statistical significance seems at least partly due to irrational, perfectionistic, beliefs about how research can be used to infer causes of therapeutic change. Irrational beliefs about controlled experimental designs and about incomplete sampling, in particular, appear to prevent appropriate consideration of probatively valuable quasi-experimental research. Models of more rational alternatives are identified, and an example of the functional advantages of adopting these rational beliefs is explicated. The example demonstrates that single-shot pre-post survey data from self-selected catch-as-catch-can samples can permit legitimate, but not absolutely certain, conclusions about the efficacy and efficiency of RET.Albert Ellis, Ph.D. is executive director of the Institute for Rational-Emotive Therapy in New York City.
