Superior motor task success has been correlated with participants’ self-reports of a larger-than-actual size of a sport-related target. In the present study, we examined whether a putting practice condition with greater success would differentially impact participants’ self-reported perceptions of the size of the putting hole during acquisition and retention. We randomly assigned participants to one of three different practice conditions and had them self-report their perceived size of the putting hole upon completion of each required putting distance. Although there were (...) no statistically significant differences between motor task success in the acquisition or retention period for the practice conditions, self-reported perceptions of target size were impacted by practice condition. During the acquisition period, participants in the self-controlled success and success-late conditions self-reported that the putting hole was larger than did participants in the success-early condition. In the retention period, participants in the self-controlled success condition perceived the target as larger than those in the success-early condition. These findings are the first to show that practice condition, independent of task success, differentially impacted self-reported perception of a target size. (shrink)

This paper puts forward a general framework for thought about human information processing. It is intended to avoid some of the problems of pipeline or stage models of function. At the same time it avoids the snare of supposing a welter of indefinitely many separate processes. The approach is not particularly original, but rather represents the common elements or presuppositions in a number of modern theories. These presuppositions are not usually explicit, however, and making them so reduces the danger of (...) slipping back into earlier modes of thought.The key point is to distinguish between persisting representations and the processes that translate one representation into another. Various classes or groups of persisting representations can be distinguished by the experimental treatments that interfere with them. In particular, there now seem to be several kinds of short-term or temporary storage, different from each other as well as from longterm memory; the translating processes also have several different modes or kinds. A particularly important aspect of the current position is that a model of this general type no longer requires some external agent to direct and control long sequences of behaviour. (shrink)

Following Brunswik (1952), social judgement theorists have long relied on regression models to describe both an individual's judgements and the environment about which such judgements are made. However, social judgement theory is not synonymous with these compensatory, static, structural models. We compared the characterisations of physicians' judgements using a regression model with that of a non-compensatory process model (called fast and frugal). We found that both models fit the data equally well. Both models suggest that physicians use few cues, that (...) they disagree among themselves, and that their stated cue use is discrepant with the models' stated cue use. However, the fast and frugal model is easier to convey to physicians and is also more psychologically plausible. Implications for how social judgement theorists conceptualise the process of vicarious functioning are discussed. (shrink)

I address some specific problems in the two target articles offered here (Rao and Palmer/Alcock: Parapsychology review and critique), which are indicative of more general problems that plague the larger debate. Because such problems are rather typical of scientific conflict, I address general problems of assessment in a second section. In a final section. I make some comments about the future of this debate.

Previous research suggests that individuals faced with risky choices seek ways to actively reduce their risks. The risk defusing operators that are identified through these searches can be used to prevent or compensate for negative outcomes. Although several factors that affect RDO selection have been identified, they are limited to static decisions conducted during descriptive tasks. The factors that influence RDO selection in dynamically unfolding environments are unknown, and the relationship between task characteristics and RDO selection has yet to be (...) mapped. We used a videogame environment to conduct two experiments to address these issues and found that experienced losses impacted risk mitigation strategy: when the task was difficult, participants experienced greater losses and were more likely to select preventive RDOs. Additionally, risk mitigation behavior stabilized as participants gained experience with the task and could be shifted by making an RDO easier to use. Exploratory analyses suggested that these risk mitigation choices were not driven by judgments of difficulty, even though participants’ JODs were accurate and aligned with task difficulty. This research suggests that while people seek preventive RDOs when tasks are difficult and risky, risk mitigation strategy is shaped by experienced losses; decision makers do not use JODs to anticipate future risks and inform risk mitigation decisions.
