Hindsight bias: An interaction of automatic and motivational factors?

If subjects are asked to recollect a former response after having been informed about the correct response, their recollection tends to approach the correct response. This effect has been termedhindsight bias. We studied hindsight bias in an experiment requiring numerical responses to almanac-type questions for physical quantities. We varied (1) the time at which the correct information was provided, (2) the encoding of the original responses by asking/not asking subjects to give a reason for the respective response, and (3) the motivation to recall correctly. We found that hindsight is less biased if reasons are given and if the correct information is provided at an earlier time. Motivation had only interactive effects: (1) With high motivation to recall correctly, the time the correct information was provided had no influence. (2) With reasons given, the variation of motivation showed no effect. These results rule out purely motivational and purely automatic explanations.     

Reduced intergroup differentiation as a result of self-categorization in overlapping categories. A quasi-experiment

A quasi-experiment was conducted to examine the effects of self-categorization in overlapping categories on intergroup differentiation. ‘Old aged women’ was used as the first, ‘sports’ as the additional category. It could be shown that intergroup differentiation was significantly reduced under crossed categorization conditions. Implications for social compensation strategies are discussed.     

A comparison of alternative theoretical approaches to smoking cessation and relapse

Two theoretical approaches to smoking cessation were compared. Participants were randomly assigned either to (a) a traditional treatment program that used contingency contracting and that emphasized the necessity for absolute abstinence (AA) or to (b) a relapse-prevention (RP) treatment that focused on gradual acquisition of nonsmoking skills. It was hypothesized that participants in the RP treatment would be less successful initially but would have better maintenance skills and thus would relapse less during a 1-year follow-up period. Each program was evaluated in two formats: group-based treatment and self-help materials. Results indicated comparable 1-year abstinence rates for all treatments, although more participants dropped out of the self-help formats. Participants in the RP intervention were more likely to lapse sooner after quitting and were more likely to quit again during the 1-year maintenance period. Exploratory analyses of successful participants suggested that women were more successful in the RP program and that men had greater success with the AA approach.     

Love and Lust Revisited: intentionality, homosexuality and moral education

ABSTRACT In his book Sexual Desire , Roger Scruton wrongly maintains that human sexual experience is essentially intentional. His thesis depends on his highly revisionary definitions of 'sexual arousal' and 'sexual desire', the artificial nature of which I expose and criticise.
He admits that homosexual desire is capable of the same kind of intentionality as heterosexual desire, and is therefore not intrinsically obscene or perverted, but he advances reasons why homosexuality is morally different from heterosexuality and is therefore an object of disapproval. His arguments presuppose 'an impassable moral divide' between the sexes and are, on his own admission, not very cogent.
Since he allows that homosexual desire is a natural and spontaneous phenomenon and also proposes that moral education should guide us towards a state in which our sexuality is entirely integrated within a life of personal affection and responsibility, consistency requires that he adopt a sexual ideology which does not discriminate against homosexuality. For homosexuals are unlikely to achieve the 'sexual integrity' which Scruton advocates (and which I endorse) if they are constantly encouraged to disparage their own sexual nature and if social institutions make no positive provision for them.     

The perception of an optical flow projected on the ground surface

In most experiments in which the importance of visual control on postural stability is studied, optical stimuli attached to vertical surfaces are used. Analyses of long-term standing readjustments generally involve back-and-forth movements of a visual scene or its projection on vertical circular screens. In a natural environment, however, visual information is largely available from the ground. The aim of the experiment reported was to assess the effect of a flow pattern simulating an open outdoor setting on motion perception and postural control. Subjects were presented with an optical texture projected onto the ground. Periods of motionless texture alternated with equivalent durations of unidirectional flows. The change of position of the subject's centre of gravity over time was recorded on a force platform. Results show that the direction of body sway corresponded with that of texture motion. Important aftereffects, as shown in linear vection experiments, were also observed. However, the latency of postural responses was much shorter than with prolonged unidirectional flows produced in other locations of the visual environment. The hypothesis of an ecological specificity of the flows perceived on the ground during terrestrial displacements is discussed.
