Monitoring in clinical trials: benefit or bias?

Monitoring ongoing clinical trials for early signs of effectiveness is an option for improving cost-effectiveness of trials that is becoming increasingly common. Alongside the obvious advantages made possible by monitoring, however, there are some downsides. In particular, there is growing concern in the medical community that trials stopped early for benefit tend to overestimate treatment effect. In this paper, I examine this problem from the point of view of statistical methodology, starting from the observation that the overestimation is caused by the statistical method adopted. Consequently, I argue that some modifications can and should be made to the present statistical framework in order not to miss the advantages the possibility of monitoring can grant.     

Whistleblowing of bullying in professional football: To report or not to report?

Only recently has research begun to focus on workplace bullying within organizations outside of traditional white-collar industries, such as professional football. While this is an important development, there remains a lack of understanding around the reporting of bullying in professional sport. In this paper, the authors explore how the professional football workplace shapes perceptions of whistleblowing and unearths individual perceptions around reporting bullying behavior. We used a phenomenological approach to gain rich experiential data from eighteen male professional football players in the UK. Interview data were analyzed in accordance with the principles of Interpretative Phenomenological Analysis. Two superordinate themes were identified from the analysis, (a) professional football’s influence on whistleblowing, and (b) the challenges of reporting bullying. These themes highlighted that the unique, institutionalized nature of professional football interacts with participants’ ability to report bullying behavior. The participants’ accounts revealed divergent perceptions around how professional football shapes the degree to which players feel they can report bullying behavior. It was apparent that the authoritarian, often abusive and intimidatory nature of professional football significantly impacts whistleblowing. Our findings demonstrate the importance of workplace context when exploring the reporting of bullying behavior. They also demonstrate the need to address organizational culture and differentiate bullying education programs to alternative workplaces.     

Exporting analogue behavioral observation from research to clinical practice: useful or cost-defective?

The special section on analogue behavioral observation (ABO) provided an in-depth review of various ABO assessment procedures. Despite their availability, however, these procedures are rarely used in clinical practice. This may result in part from the traditions on which most ABO assessments are based, from distinctions between clinical and research assessment environments, and from the need for more information about the cost-effectiveness of ABO strategies for meeting specific needs of clinicians in applied settings. Suggestions for bridging the research-clinical gap involve investigating more thoroughly when ABO does and does not provide useful information for various purposes in applied settings and increasing accessibility and cost-effectiveness of ABO procedures for practitioners.     

Schema anticipation in recall: memory process or report strategy?

Summary This article reports an experimental investigation testing the hypothesis that recall reports are systematically biased by the recaller's knowledge about who is to receive the recall report, while that bias is absent from a recognition test. Subjects listened to one of two versions of a story recounting John's visit to the doctor. After the story was read, subjects were asked to recall the story either with standard-recall instructions or with instructions to recall for peers, for Martians, or for a contest. In a fifth condition, subjects performed a filler activity, viz., the recall of a personal experience. After the recall test subjects were administered a recognition test. Between the groups no systematic differences in memory performance were observed in the recognition test. Recall for peers appeared to be poorer than recall in the other conditions. Subjects in the recall for a contest condition scored higher than the subjects in the other groups. Not only did groups differ with respect to bias, but there were also systematic differences in the memory or discrimination scores. The findings are discussed within the framework of schema theory.     

Individual differences in syllogistic reasoning: deduction rules or mental models?

Two studies examined the correlates of reasoning ability on a syllogistic reasoning task in subjects who lacked formal background in logic. The main issue addressed was the extent to which reasoning proficiency arises from the consideration of multiple possible set relations (mental models) as opposed to explicit or implicit reliance on deduction rules. Evidence for the use of both models and rules was obtained. Although "good" and "poor" reasoners differed even when time constraints were imposed (consistent with the supposition of a better set of rules among good reasoners), good reasoners showed more improvement and chose to take longer amounts of time when time constraints were removed, suggesting that they considered more alternatives than did the poor reasoners. A comparison between these two groups and a third group of subjects, graduate students who had studied logic, reveals striking differences in both accuracy and speed.     

Mueller-Lyer decrement: practice or prolonged inspection?

Noting the similarity between the illusion decrement and selective adaptation paradigms, Long has challenged the view that illusion decrement effects reflect a strategic--as opposed to a structural--underlying mechanism, and has called for further research on this issue. To investigate the confound between prolonged free inspection and repeated trials in the standard decrement procedure, the effects of three inspection conditions (continuous, intermittent, and immediate) on the magnitude of the overestimation Mueller-Lyer illusion have been assessed under two levels of trials (a total of two or six judgments). Significant illusion decline was found only under conditions of repeated trials, with either continuous or intermittent inspection. These findings do not support the predictions of purely structural theories (including neural adaptation and efferent readiness theories), according to which degree of decrement should be determined solely by viewing time. Instead, the data demonstrate that illusion decrement is a product of practice, providing converging evidence for the view of decrement as involving a cognitive 'recalibration' or learning process.     

Behavioral contrast in short term memory: Serial binary memory models or parallel continuous memory models?

This paper develops a model wherein STM primacy as well as recency effects can occur. The STM primacy effects can be used to generate correct immediate recall of short lists that have not been coded in LTM. The properties of the model are interpreted in terms of explicit neural mechanisms. The STM primacy effect is a behavioral contrast effect that is analogous to the behavioral contrast that can occur during discrimination learning. The adaptational mechanism that accounts for these effects is also implicated in data on reaction time, retinal adaptation, ratio scales in choice behavior, and von Restorff-type effects. Its ubiquitous appearance is due to the fact that it solves a universal problem concerning the parallel processing of patterned data by noisy cells with finitely many excitable sites. It is argued that the STM primacy effect is not measured in interference experiments because it is masked by competitive STM interactions. These competitive interactions do not prevent the LTM primacy effect from influencing performance. The paper criticizes recent models of STM that use computer analogies to justify binary codes, serial STM buffers, and serial scanning procedures. Several deficiencies of serial models in dealing with psychological and neural processing are overcome by a model in which continuous STM activities and parallel real-time operations play an important role.     

Ecologically based interventions in residential and school facilities: theory or practice?

An overriding theme within systemic therapies has been the need for the development of a comprehensive and coordinated network of community-based treatment resources to effectively meet the unique needs of adolescents experiencing emotional difficulties. An ecosystemic approach to meeting this need focuses on the interdependence of such environmental elements as the residential institution, the school, various social agencies, peer group, and the family in the life of the adolescent. Ecological interventions consider the significant environmental elements, the relationships among these elements, and the adolescent's interaction with them. Such an ecosystemic model is essential to planning and implementing academic and social programs for our youth. This paper illustrates some important differences between interdisciplinary and ecological perspectives. It highlights the use of ecosystemic models in residential and school facilities and also enumerates areas where ecologically based changes might be appropriate. In addition, it outlines operational guidelines focusing on the reintegration of the adolescent from the institution back to the neighborhood school.     

Can research influence clinical practice?1

After briefly reviewing the unfavourable reception accorded empirical research by parts of the psychoanalytic community, as well as some of the benefits to clinical practice of analysts being involved in research activities, the author examines whether the findings of process and outcome research in psychotherapy and psychoanalysis can help identify the most appropriate forms of intervention for producing therapeutic change, given the specific condition of the patient and the relationship that the individual establishes with the analyst. He argues that research findings can influence clinical practice on various levels and in different areas, and goes on to examine a number of related issues: the specificity of therapeutic interventions versus the relevance of common curative factors; the dyadic conception of technique and ways of understanding the therapeutic action of the treatment alliance; and the strategic or heuristic conception in psychoanalytic therapy. Finally, the author presents clinical material with the aim of illustrating how the knowledge acquired through research can be applied to psychoanalytic treatment.
