Assessing the Integrity of Clinical Data: When is Statistical Evidence Too Good to be True?

Evidence, as viewed through the lens of statistical significance, is not always as it appears! In the investigation of clinical research findings arising from statistical analyses, a fundamental initial step for the emerging fraud detective is to retrieve the source data for cross-examination with the study data. Recognizing that source data are not always forthcoming and that, realistically speaking, the investigator may be uninitiated in fraud detection and investigation, this paper will highlight some key methodological procedures for providing a sounder evidence base for withdrawing from a study on grounds of integrity. The promotion of patient safety is paramount. However, there is a broader rationale for disseminating these ideas. This includes empowering researchers to optimize their personal integrity, make informed choices regarding membership of future research collaborations and successfully voice their concerns to journal editors, particularly where a conflict of interests can render such dialogues particularly difficult. Recommendations will be supported by topical case studies and practical steps involving data exploration, testing of baseline data and application of Benford’s Law. While this paper has a clinical focus, the advice provided is transferrable to a wide range of multidisciplinary research settings outside of Medicine.     

Mirror,mirror on the wall,who’s the fairest of them all? Thinking that one is attractive increases the tendency to support inequality

Five studies tested the hypothesis that self-perceived attractiveness shapes people’s perceptions of their social class (subjective SES), which, in turn, shape how people respond to inequality and social hierarchies. Study 1 found that self-perceived attractiveness was associated with support for group-based dominance and belief in legitimizing ideologies, and that these relationships were mediated by subjective social class. Subsequent experiments showed that higher self-perceived attractiveness increased subjective SES, which in turn, increased SDO (Study 2 and Study 5); promoted stronger beliefs in dispositional causes of inequality (Study 3); and reduced donations to a movement advocating for social equality (Study 4). By contrast, lower self-perceived attractiveness decreased subjective SES, which in turn, led to a greater tendency to reject social hierarchies and to construe inequality in terms of contextual causes. These effects emerged even after controlling for power, status, and self-esteem, and were not simply driven by inducing people to see themselves positively on desirable traits (Study 4 and Study 5).     

Too Old to Train or Reprimand: The Role of Intergroup Attribution Bias in Evaluating Older Workers

Purpose

The purpose of this study was to explore the role rater and target age play in the evaluations of poorly performing workers. Intergroup attribution theory suggests that rater age predicts the attributions made for the poor performance of older workers.

Design/Methodology/Approach

In this study, 203 supervisors in various industries completed measures of causal attribution and evaluations for a poorly performing hypothetical subordinate.

Findings

Compared to the poor performance of younger targets, the poor performance of older targets was more likely to be attributed to external and controllable causes by older raters and more likely to be attributed to stable causes by younger raters. These attributions predicted willingness to punish and likelihood to provide training.

Implications

Our findings were partially supported by intergroup attribution theory and suggest that this theory may be useful in understanding how older workers’ performance is evaluated.

Originality/Value

This is one of the first studies to utilize intergroup attribution theory among supervisors in exploring how older workers are evaluated in the workplace and to demonstrate that the theory predicts how older workers’ poor performance will be attributed. Our study provides evidence that when evaluating a poorly performing older target, older raters will be more inclined to attribute this performance to controllable causes and thus be more punitive than younger raters. Further, we provide some evidence that raters will be more punitive and less willing to provide training when evaluating poorly performing targets to whom they are similar.     

The building blocks of social communication

In the present review, social communication will be discussed in the context of social cognition, and cold and hot cognition. The review presents research on prosody, processing of faces, multimodal processing of voice and face, and the impact of emotion on constructing semantic meaning. Since the focus of this mini review is on brain processes involved in these cognitive functions, the bulk of evidence presented will be from event related potential (ERP) studies as this methodology offers the best temporal resolution of cognitive events under study. The argument is made that social communication is accomplished via fast acting sensory processes and later, top down processes. Future directions both in terms of methodology and research questions are also discussed.     

Typhoid Pollyanna: The effect of category valence on retrieval order of positive and negative category members

Previous research suggests that people process pleasant information more efficiently than unpleasant information. This phenomenon has been illustrated in a variety of contexts and paradigms, and is frequently referred to as the Pollyanna principle. One important aspect of the Pollyanna principle is that people tend to retrieve pleasant members of a category from semantic memory prior to unpleasant members of the same category. However, we propose that the retrieval advantage of favourably viewed category members holds only for positive categories and that prototypicality of category members might be a better predictor of ease of retrieval than favourability. These possibilities were tested in two studies. In Study 1, favourability effects on retrieval order were observed for positive categories but not for neutral or negative categories. In Study 2, prototypical category members were retrieved before less prototypical category members for both positive and negative categories. These results suggest that the Pollyanna principle might be the result of a confound between favourability and prototypicality for members of favourable categories.     

Bilingual Generation Effect: Variations in Participant Bilingual Type and List Type

Slamecka and Katsaiti (1987, Experiment 1) reported that there is no generation effect with bilingual materials under intentional learning instructions. In contrast, O'Neill, Roy, and Tremblay (1993, Experiment 1) demonstrated a bilingual generation effect when an incidental learning set was induced. In the present experiment, the possibility that another procedural variation between the two studies accounts for the disparate findings was examined. A 2-stimuli (read bilingual translations, generate bilingual translations) list was compared with a 3-stimuli (read bilingual translations, generate bilingual translations, read unilingual repetitions) list, in accordance with the procedures used in the earlier experiments. Under incidental learning conditions, for both list types, a strong generation effect was found. Participant type—coordinate or compound bilingualism—was also varied. The generation effect was much larger for compound bilinguals than for coordinate bilinguals, presumably because of a greater difference in the allocation of attention to read than to generate items by compound bilinguals.     

Reply to Panel Questions

This commentary on papers by Neil Altman and Rachel Peltz argues that while the type of political culture in which one lives has a significant impact on the practice of psychoanalysis, no direct line can be drawn from psychoanalytic theory to any particular political persuasion. It is one thing to argue that psychoanalytic insights offer a way of thinking about political relations; it is quite another to suggest that they can be used to promote or justify a political agenda. While Altman and Peltz theorize about the negative impact of manic defense in contemporary culture, this commentary suggests that there are natural fluctuations in one's ability to respect inner reality and a degree of manic defense employed in everyday life that is quite normal. We all use reality to gain reassurance against death inside. But, when we are “distracted from distraction by distraction” (Eliot, 1971, p. 120) external objects are prematurely deadened so that the needed reassurance through external reality becomes increasingly elusive. Challenging some of Altman and Peltz's political assumptions, the commentary suggests that if psychoanalysis is to contribute to the political realm, it must do so on the basis of how it differs from other approaches to understanding what it means to be a human being.
