The generation effect refers to the memory advantage of words that have been generated rather than read. Such a read-generate comparison confounds qualitative task differences and raises methodological problems. A revised methodology is proposed circumventing these problems in that the encoding task is held constant and all stimuli have to be generated, but the degree of generativeness (i.e. the amount of cueing) is varied. In Experiment 1, 1, the (refined version of the) generation effect is demonstrated in a within-subjects design; with increasing generation activity left to the subject, free recall performance increases. No effect is obtained for degree of target masking. The same finding is replicated and shown to be independent of self-paced study time when generative activity is manipulated between subjects (Experiment 2) or within subjects (Experiment 3). As all learning trials involve generation, encoding time is controlled statistically, and free recall is used as a measure of memory, this refined generation effect cannot be explained as an artifact of selective attention or elaboration. Rather, generative activity seems to increase the mobilization of cognitive resources. This motivational account is supported by Experiment 4 showing an enhanced generation effect for positive mood. 相似文献

The relationship between conservation skills and subjective responsibility (SR) in moral judgment was examined in two studies. The Kohlberg ontogenetic priority hypothesis stating that conversation is a necessary but not sufficient condition of SR was pitted against the common structural basis hypothesis advanced by Damon. Piaget's notion of heteronomy as a combination of preoperational thought and unilateral respect was studied by using the behavioural independence tasks by Subbotsky as indicators of unilateral respect. A teaching experiment using Galperin's and Obukhova's method to induce conservation indicated significant transfer from conservation to SR. SR was found to be more susceptible to regression over a 3–month period than conservation. Conservers were less likely to regress on SR than nonconservers. Unilateral respect was related to objective responsibility but not to conservation. Taken together the data fail to support Kohlberg's ontogenetic priority hypothesis and only partially support the Piaget and Damon model of a common underlying structure. It is concluded that SR judgments largely reflect individual judgmental strategies and the effect of conservation on SR is intepreted in terms of increasing cross-situational consistency in the use of these strategies. 相似文献
