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. 相似文献

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. 相似文献
