Do alcoholic amnesic patients passively rehearse verbal information?

Recently it has been claimed that alcoholic amnesic patients mainly engage in passive repetitive rehearsal during spontaneous learning and that this contributes to their memory problem. To test this hypothesis further, two experiments were conducted which compared list learning in amnesic patients and normal controls. In Experiment I both groups of subjects were required either to learn a list which was presented five times consecutively with free recall following each presentation, or they were asked to repeat each word out loud as they saw it and carry on doing so until the next word was shown. Five presentation trials were given and free recall was again tested after each presentation. It was predicted that if the amnesics' spontaneous form of learning involved only passive repetition there should be no difference between learning and repetition for this group while the controls should show an impairment in repeating compared to learning. The results showed that both groups of subjects were impaired to the same extent with repeating compared to learning and it was concluded that spontaneous learning was similar in both groups and that neither group merely passively rehearsed during spontaneous learning. A second experiment examined recognition performance of the two groups of subjects after learning or repeating lists of 20 words. Recognition was tested with distractors which were irrelevant, acoustically similar, graphemically similar, or semantically similar to the target word. It was found there were no differences between either of the groups in the pattern of errors made over the different distractor types. It was thus concluded that there was no encoding or rehearsal abnormality in the amnesic group. The possibility of differences between groups of alcoholic amnesics was discussed as well as the putative role of slow cognitive processing in their memory problems.     

A reevaluation of the absenteeism-job satisfaction relationship

Previous reviews of the relationship of employee absenteeism to job satisfaction have largely neglected the size of the relationships reported and the artifacts that can affect statistical tests of significance. This paper applies the F. L. Schmidt-J. E. Hunter (1977, Journal of Applied Psychology, 62, 529-540) model of validity generalization in assessing the nature and strength of the relationship of absence to attitudes. Issues concerning the reliability and validity of absence measures are addressed, correlations between absence and job satisfaction are compiled and summarized, and an agenda for future research is set out. Considering the reliability estimates reported for the Frequency, Attitudinal, and Time Lost indices, the Time Lost Index was found to be the most reliable (r xx = .66, SD = .28). Factor analyses of intercorrelations among absence measures provided tentative support for a voluntary-involuntary absenteeism distinction. Combining all measures of satisfaction and all measures of absences, the mean correlation between absence and attitudes is -.09 (SD = .13). In addition to more comprehensive theory-guided multivariate research, future studies should aim toward a reconceptualization of absenteeism as a construct to take into consideration the perceptions of the workers themselves.     

Similarity of attitudes and constructs in children's friendships

Sex prejudice in children's friendships has frequently been noted. This study examined the role of similarity of attitudes and personal construct ratings in this effect. Subjects were two classes of school children, aged 7–8 and 9–10 years. There were 29 children in each class. Subjects completed an attitude scale, construct rating scale, and sociometric questionnaire. Similarity effects were primarily in the younger children. Boys were more similar to each other in attitudes than were girls, and girls were more similar to each other in construct ratings than were boys (p < .001); there was greater similarity of attitudes and construct ratings in friendship rather than nonfriendship comparison dyads (p < .01). The sociometric data, when compared with sociometric data collected 6 months earlier, showed that these results could not be due to sex differences in the stability of friendships but rather suggested age and sex differences in the informational bases of friendships in middle childhood.     

Constraints on Pavlovian conditioning of the pigeon: Relative conditioned reinforcing effects of red-light and tone CSs paired with food

Recent Pavlovian conditioning experiments presented all possible CS-US combinations of red-light and tone CSs and food and shock USs to separate groups of pigeons. Pigeons receiving shock USs demonstrated conditioned head raising followed by prancing to both CSs, but CRs were acquired more rapidly to tone than to red light. Although pigeons receiving food USs rapidly acquired a conditioned response of pecking to the red-light CS, there was no evidence of conditioned responding in groups receiving tone-food pairings. This outcome left open the possibility that Pavlovian pairings of tone and food may have resulted in association formation that was not revealed in performance. The present series of experiments attempted to reveal that association, using an indirect method of assessment, conditioned reinforcement. Experiment 1 demonstrated that both red light and tone paired with food became positive conditioned reinforcers, suggesting that an association between tone and food was formed in the same number of Pavlovian conditioning trials that previously failed to yield any direct evidence of conditioning. Experiment 2, which presented fewer conditioning trials, revealed that the tone-food association was formed less rapidly than the red light-food association. Experiment 3 demonstrated that the observed outcomes were not attributable to unconditioned, rather than conditioned, reinforcing effects of the Css.     

A developmental perspective on reading dysfunction: Accuracy and rate criteria in the subtyping of dyslexic children

Children referred with specific reading dysfunction were subtyped as accuracy disabled or rate disabled according to criteria developed from an information processing model of reading skill. Multiple measures of oral and written language development were compared for two subtyped samples matched on age, sex, and IQ. The two samples were comparable in reading fluency, reading comprehension, word knowledge, and word retrieval functions. Accuracy disabled readers demonstrated inferior decoding and spelling skills. The accuracy disabled sample proved deficient in their understanding of oral language structure and in their ability to associate unfamiliar pseudowords and novel symbols in a task designed to simulate some of the learning involved in initial reading acquisition. It was suggested that these two samples of disabled readers may be best described with respect to their relative standing along a theoretical continuum of normal reading development.     

Predicting vocational performance of engineers from selected vocational interest,personality, and scholastic aptitude variables

The study examines the validity of the ACE and selected subscales of the EPPS and SVIB in predicting the vocational performance of engineers. Multidimensional criteria of vocational performance assessed from both external and internal frames of reference were employed. Six predictors were related to 17 vocational performance criteria; of the 102 tests that were made, 7 were found to be statistically significant. The results indicate that, in general, vocational performance cannot be accurately predicted by vocational interest, personality, and scholastic aptitude variables. The only consistent finding was that subjective ratings of vocational performance were predicted by SVIB Group V scores; a “self-esteem” interpretation was posited. Implications of the results for counselors and employers were discussed.     

Dichhaptic hand-order effects with verbal and nonverbal tactile stimulation

The palms of normal right-handed subjects were stimulated dichhaptically, i.e., with competing, bimanually presented tactile stimuli consisting of pairs of letters, pairs of digits, or pairs of line orientations. The subjects were required to identify both stimuli in a particular order, and order of report was compared between hands and across stimulus materials. Results indicated right-hand superiority for letters and left-hand superiority for lines; no hand differences occurred for digits. However, observed differences between hands appeared with second reports only, suggesting that measures of tactile storage are more sensitive to laterality differences than measures closer in time to actual stimulation.
