Aspects of Psychosomatic Orchidalgia

Children aged 5 to 9 years matched the shape of (a) small squares embedded in large rectangles and (b) small rectangles embedded in large squares. Predictions made were that (a) the influence of the whole on the perception of the part would be greatest at the 5-year-old level and (b) this effect of the whole would make the parts look to the child somewhat like the whole figure of which the part is a member. Both predictions were supported by the data. The 5-year-olds perceived the small squares as more rectangular, and the small rectangles as more square-like, significantly more than the older age groups, each result representing a shift towards the shape of the whole configuration.     

Unemployment as a chronic stressor: A systematic review of cortisol studies

Objective: Unemployment is a type of chronic stressor that impacts human health. The reasons for how the stress of unemployment affect health is still a matter of discussion. One of the pathways from chronic stress to ill health is mediated by cortisol, and so we set out to compile extant data on how its secretion is affected by unemployment.

Design: A systematic literature search was conducted to establish the cortisol dysregulatory effects of this stressor.

Main outcome measures: Only studies that specifically examined the effects of unemployment on cortisol excretion, and were written in English were included.

Results: Ten reports were obtained and synthesised to determine the severity and complexity of the effect of unemployment on cortisol secretion. The resulting combined evidence is mixed in terms of degree or dynamic of relationship.

Conclusions: The differences between the cumulate findings of the studies can be understood in the context of the lack of both standardised methodology and an absence of consensus on unemployment definition. We propose existing methodologies may be strengthened by acknowledging and accounting for the individual characteristics that may be relevant to the stress experience of unemployment.     

CAN A PERPETRATOR WRITE A TESTIMONIO? Moral Lessons from the Dark Side

By posing a heuristically provocative question, this essay compares and explores in some detail the testimonies of three infamous perpetrators from the Nazi period—Albert Speer, Rudolph Hoess, and Adolf Eichmann—for what they reveal about their motives, ideological thinking, and strategies of denial and self-deception, as well as influences from their social, political, and cultural context. The conclusion drawn is that many of the external and internal factors at work in them are recognizable to us as features of our own moral experience and, further, that this recognition is particularly important for motivating self-scrutiny in our own lives for any hints of impending complicity with moral evil.     

Task switching: the effect of task recency with dual- and single-affordance stimuli

When we switch to a new task, performance is transiently relatively poor, but improves dramatically after one trial. Such a “switch cost” may result from the preceding task being highly primed while the new task is not yet primed. This predicts that it should become more difficult to switch back to Task A when more trials of Task B have intervened. Such a lag effect has been found in some but not in most previous experiments, and to resolve this discrepancy we examined the effects of task lag with different stimuli. We found that when stimuli uniquely and clearly cued the task—minimizing the need for control—switch reaction time increased with task lag. However, when the need for control was increased by using similar or identical stimuli in the two tasks, this lag effect was abolished or reversed. Thus only when control processes are minimized can priming explain the difficulty of switching back from Task B to Task A. Second, we asked how the impact of control is mediated in conditions where it is not minimized. If it is mediated through altering the relative activation states of competing tasks, then as it becomes easier to do one task—the relative task-set activation state is tipped in that task's favour—it should always become harder to do the other task. On the other hand, if control bias affects switch performance directly, this relationship need not hold. We found that as it becomes easier to perform one task it can become easier, not harder, to switch to the competing task. Thus control bias must act directly on switch performance, rather than only through its influence on relative task-set activation.     

COMPARATIVE ETHICS, A COMMON MORALITY, AND HUMAN RIGHTS

This essay is a brief attempt to summarize and evaluate the contributions that Democracy and Tradition makes to the field of comparative ethics. It is argued that the potential impact of these contributions would be strengthened by engagement with the common morality already imbedded in international human rights norms.     

Conflict in object affordance revealed by grip force

Viewing objects can result in automatic, partial activation of motor plans associated with them-"object affordance". Here, we recorded grip force simultaneously from both hands in an object affordance task to investigate the effects of conflict between coactivated responses. Participants classified pictures of objects by squeezing force transducers with their left or right hand. Responses were faster on trials where the object afforded an action with the same hand that was required to make the response (congruent trials) compared to the opposite hand (incongruent trials). In addition, conflict between coactivated responses was reduced if it was experienced on the preceding trial, just like Gratton adaptation effects reported in "conflict" tasks (e.g., Eriksen flanker). This finding suggests that object affordance demonstrates conflict effects similar to those shown in other stimulus-response mapping tasks and thus could be integrated into the wider conceptual framework on overlearnt stimulus-response associations. Corrected erroneous responses occurred more frequently when there was conflict between the afforded response and the response required by the task, providing direct evidence that viewing an object activates motor plans appropriate for interacting with that object. Recording continuous grip force, as here, provides a sensitive way to measure coactivated responses in affordance tasks.
