Dissonance motivation: Its nature,persistence, and reinstatement

This paper examines whether arousal is a necessary component of the motivation to reduce dissonance. Alternative responses to attitude-behavior inconsistency include attitude change, explaining the behavior by a consonant cognition (i.e., low choice), and attributing the dissonance-induced state to an alternative source, such as the purported side effects of an ingested “drug.” For conditions in which there are few consonant cognitions (i.e., high choice), a comparison of different “drug” conditions in which attitude change does or does not occur was expected to clarify which components of the dissonance-induced state mediate attitude change. Attitude change occurred in high choice conditions where the “drug” was described as pleasant, but not in high choice conditions where the “drug” was described as unpleasant or in a low choice condition. In addition, when the “drug” was descibed as arousing there was, if anything, more attitude change than when the “drug” was described as nonarousing. These results suggest that unpleasantness and not arousal per se is the motivating factor in dissonance reduction. The effects of the passage of time and reinstating the counterattitudinal behavior on the alternative responses to attitude-behavior inconsistency were also examined. Subjects returned 2 weeks later, stated their attitudes, recalled their original counterattitudinal essay, and again stated their attitudes. Although there was a general decrease in attitude change during this period, the pattern of attitude change remained basically the same. Attitude change following reinstatement increased from its original level only in those conditions where it had been initially attenuated through misattribution or a consonant cognition.     

Interpreting inclusion: A contribution to the study of the child's cognitive and linguistic development

Six experiments are reported which examine the young child's ability to compare included and nonincluded sets. Results indicate that with certain forms of task presentation most 3- to 5-year-old children can compare part with whole. Further, errors which occur in inclusion tasks are similar to errors which occur in tasks involving comparison of nonincluded sets. Thus young children can solve inclusion problems, and their customary failure to do so does not arise because the problem requires comparison of a whole with an included part. Employing a distinction between intended tasks (those which the adult wishes the child to complete) and received tasks (those which the child, in fact, completes) the studies indicate how linguistic and perceptual aspects of the presented information may interact with the child's assumptions about the nature of the task to be completed.     

Individual differences in cognition: Relationship between verbal ability and memory for order

The crucial role of order information in language has led to the suggestion that psychometrically measured verbal ability may be related to memory for order. The literature pertaining to this hypothesis is briefly reviewed and various methodological difficulties discussed. The results of three experiments indicated that (a) order and item information may be retained separately; (b) verbal ability is related to the short-term recall of order; (c) verbal ability is unrelated to memory for order when testing involves recognition rather than recall; and (d) the relationship between verbal ability and memory for order is most pronounced when the originally presented order must be transformed at output (as in the “digits backward” task). An output process in which material is decoded and held in an output buffer until decoding is complete is viewed as the most likely locus of the verbal ability-memory for order relationship.     

Computer tomographic localization, lesion size, and prognosis in aphasia and nonverbal impairment.

Computerized tomography scans (80) were used to localize infarcts in 70 patients. Twenty-three aphasics were scanned within 35 days from onset, 39 beyond a year, and 18 were nondominant cases. Aphasics were also grouped according to test scores obtained within 35 days of scan. Chronic global aphasics have larger lesions than persisting Broca's aphasics. The area of persisting Broca's aphasia is similarly anterior but larger than that of recovered motor aphasia. Anomic aphasics evolve from Broca's and Wernicke's types with differing localization. Lesion size correlated with severity and recovery, and comprehension among the subtests.     

Differential effects of personality on access to various long-term memory codes

Arousal, as indexed by personality measures, has been related to memory encoding, organization, and retrieval. In an attempt to investigate one of the component information-processing mechanisms underlying both encoding and retrieval, the effects of introversion-extraversion on performance in a simultaneous matching task was investigated. As predicted from earlier research, personality did not influence performance on a physical identity matching task but extraverts were faster than introverts in making taxonomic category matches (a semantic task). Somewhat unexpectedly, extraverts were also faster at making “homophone” identity matches. Arousal, then, appears to influence access to long-term memory codes of any type—a characteristic that may be reflected in tests of both encoding and retrieval.     

Age,and midcareer crisis: An empirical study of academics

This study develops an empirical basis for examining the midcareer crisis/ transition period of academic staff surveyed by questionnaire in four Australian Universities and Colleges. A total of 672 usable returns were obtained, representing a response rate of 52% of the academic staff. Principal components and factor analysis were used to establish latent social-role variables. Analysis of variance and covariance was applied using the latent social-role variables as dependent variables and occupational attributes such as age, sex, etc., as independent variables. The variable age was isolated from the larger study in this paper to illustrate empirically a midcareer crisis period for the population studied which is consistent with the general literature on midcareer crisis/transition.
