成人日常问题解决的老化研究

日常问题解决能力是近十几年来老年心理学中研究比较活跃的一个领域。本文介绍了有关日常问题解决研究的四种理论,即心理测量的智力内隐理论、形式后思维的辨证思维理论、信息加工理论和社会认知与智慧理论,及其初步的研究成果,并进一步指出在理论上整合和在实践中开展干预的研究方向。     

A model theory of induction

Theories of induction in psychology and artificial intelligence assume that the process leads from observation and knowledge to the formulation of linguistic conjectures. This paper proposes instead that the process yields mental models of phenomena. It uses this hypothesis to distinguish between deduction, induction, and creative forms of thought. It shows how models could underlie inductions about specific matters. In the domain of linguistic conjectures, there are many possible inductive generalizations of a conjecture. In the domain of models, however, generalization calls for only a single operation: the addition of information to a model. If the information to be added is inconsistent with the model, then it eliminates the model as false: this operation suffices for all generalizations in a Boolean domain. Otherwise, the information that is added may have effects equivalent (a) to the replacement of an existential quantifier by a universal quantifier, or (b) to the promotion of an existential quantifier from inside to outside the scope of a universal quantifier. The latter operation is novel, and does not seem to have been used in any linguistic theory of induction. Finally, the paper describes a set of constraints on human induction, and outlines the evidence in favor of a model theory of induction.

The antinomy of science and democracy in modern China

Up to now Chinese academia has been addicted to inviting the twin goddesses of democracy and science, but has regrettably ignored the innate incongruity between them, which has led to the rise of scientism. May 4th pioneers first introduced this value system, but tension between these values subsequently led to a prevailing preference for science over freedom. The early Marxists defined freedom as obedience to social laws formulated in Marxist ‘science’, while Maoism finalized the Sinicization of Marxism with a belief in iron‐bound social laws and in human beings as mere political means, mercilessly suppressing any expression of free will.     

Phonological short‐term memory and vocabulary development: further evidence on the nature of the relationship

The nature and generality of the developmental association between phonological short‐term memory and vocabulary knowledge was explored in two studies. Study 1 investigated whether the link between vocabulary and verbal memory arises from the requirement to articulate memory items at recall or from earlier processes involved in the encoding and storage of the verbal material. Four‐year‐old children were tested on immediate memory measures which required either spoken recall (nonword repetition and digit span) or recognition of a sequence of nonwords. The phonological memory–vocabulary association was found to be as strong for the serial recognition as recall‐based measures, favouring the view that it is phonological short‐term memory capacity rather than speech output skills which constrain word learning. In Study 2, the association between phonological memory skills and vocabulary knowledge was found to be strong in teenaged as well as younger children, indicating that phonological memory constraints on word learning remain significant throughout childhood.

Preferences for and evaluation of self‐relevant information depending on the elaboration of the self‐schemata involved

Previous findings have shown that some reactions (e.g. satisfaction with feedback) are guided by self‐enhancement theory, whereas other reactions (e.g. perceived feedback accuracy) have been shown to follow predictions of self‐consistency theory. The Integrative Self‐Schema Model (ISSM) assumes that these effects should be moderated by the elaboration of the self‐schema involved: This assumption was tested in an experimental study: 72 participants received fictitious feedback on different personality dimensions allegedly based on an adjective checklist. This feedback was either consistent with self‐perceptions, more positive than expected, or more negative than expected, and addressed highly elaborated (schematic) or less elaborated (aschematic) personality dimensions. Satisfaction, feedback accuracy and interest in further information were analysed as dependent variables. The experimental results clearly confirmed the hypotheses derived from the ISSM for satisfaction and perceived feedback accuracy. A self‐consistency effect regarding perceived feedback accuracy was found only for feedback on schematic dimensions but was attenuated on aschematic dimensions. A self‐enhancement effect regarding satisfaction was found only on aschematic dimensions. This finding was reversed on schematic dimensions. Finally, interest in further information did not follow the predictions made by the ISSM. Copyright © 1999 John Wiley & Sons, Ltd.     

Social Discrimination in a Personnel Selection Context: The Effects of an Authority's Instruction to Discriminate and Followers' Authoritarianism1

Social discrimination in a personnel‐selection context was studied using an in‐basket exercise. West German participants had to select personnel from an applicant pool that included West German applicants (in‐group members) and East German applicants (out‐group members). As predicted, we found a main effect for an authority's instruction to discriminate against out‐group members. This main effect was, as predicted, qualified by an Instruction Right‐Wing Authoritarianism (RWA) interaction effect. Only high scorers on RWA discriminated against out‐group members when instructed to do so.     

Effects of Childhood Sexual Abuse on Client Spiritual Well‐Being

Forty‐three individuals receiving psychotherapy for childhood sexual abuse and 34 clients who sought psychotherapy for other reasons were compared on several aspects of spiritual functioning. The 2 groups did not differ significantly in spiritual well‐being. However, both groups scored lower than samples of medical outpatients and hospice workers. Most reported initiating and discussing spiritual issues during therapy, were satisfied and comfortable with these discussions, and rated spirituality as important to problem resolution. They also listed several obstacles to spiritual development. Possible research and practice implications are discussed.
