The work on this paper was done in the research project V ra begrepp om spr k supported byHumanistisk-samhälls-vetenskapliga forskningsr det. I am indebted to Per Martin-Löf, Hans Ruin, Pär Segerdahl, and Sven Öhman for valuable comments on a previous version of this paper. Thanks to the comments of the anonymous referee I was able to improve some formulations in the paper.  相似文献

Summary An experiment was conducted to determine whether the processes underlying memory for enacted and nonenacted events are the same or different. The experimental paradigm used was that of recognition failure of recallable information. At study subjects were given verbal commands (e.g., break the match, roll the ball), that they were to remember or enact and remember. At test subjects were first asked to recognize the noun in each command in the absence of the verb and then to recall the noun with the verb present as cue. Half the subjects were given the two tests in the reverse order. The results demonstrate that enactment and nonenactment differ with respect to the degree of dependence/independence between recognition and recall. In the enactment condition recognition and cued recall are completely independent and in the nonenactment condition they are almost completely dependent.  相似文献

This review examines recent books on altruism and prosocial behaviour. Psychological approaches, biological approaches, and economic approaches are covered. The list of variables known to influence prosocial behaviour includes situational determinants, motivational orientations, and personality variables. Psychological theories emphasizing norms, cost-benefit calculations, and developmental factors have been used successfully to explain prosocial behaviour. Attention is given to models of helping and social and therapeutic treatment programmes. Genetic variables in prosocial behaviour are also reviewed.  相似文献

Summary Three experiments are reported to test a claim by previous subjects that lack of motivation for performing well in memory experiments yielded less than optimal performance. In each experiment the subjects of one group were informed of monetary incentives prior to study; in a second group they were informed of these incentives after study but prior to the test; no mention of incentives was made to the subjects of a third group. Recall and recognition procedures were used to assess memory performance. The data of all three experiments demonstrated no differences between the three groups with respect to performance. The claim that subjects in regular memory experiments would typically perform less than optimally is thus rejected. Subjective reports, however, revealed that incentives had affected the amount of effort put into the memory tasks. This dissociation between performance data and subjective reports is discussed in relation to the concept of motivation.  相似文献

Controversies, i.e., multiple theory confrontations, may have a strong impact on the development of science. By an analysis of the so-called “resonance controversy” in chemistry the view that controversies and their resolution differ considerably from the process of theory succession is defended. It is argued that controversies are symptomatic of foundational problems, produce theory-scattering or domain-splitting, and induce ontological shifts. An explication is given of the role of existence claims and the applicability of Ockham's Razor in the resolution of controversies. The requirement of a realistic interpretation of theories at all times, as defended by some philosophers, is criticised.  相似文献
