Transfer of training: Effects of successive pretraining of components in a dimension-abstracted oddity task

An experiment was conducted investigating the effects of training two components of a dimension-abstracted oddity problem, oddity responding and attention. All Ss were given a series of three problems. Type of oddity training was manipulated on Problem 1, and Ss learned (1) an oddity response in a problem whose format was the same as the final transfer problem, (2) an oddity response in a problem whose format was different from the final problem, or (3) no oddity response. Attention training was manipulated on Problem 2. The results indicated that Ss given same format oddity training and appropriate attention training were able to integrate that information on the final problem, that the probability of transferring the oddity response learned on Problem 1 to Problem 3 depended upon the similarity of the task formats, and that the two trained components tended to combine in an interactive fashion.     

Disfluent speech associated with brain damage

The frequency and type of disfluencies in the spontaneous speech of 15 people with Broca's aphasia and right hemiplegia was studied. Two aged-matched control groups (15 nonaphasic stroke patients with left hemiplegia and 15 normals) were also studied. The frequency of disfluencies in the speech of aphasics was three times greater than that in the speech of either control group. However, most of the disfluencies uttered by aphasics were of the types commonly found in speech of normals.     

The effects of alternatives on the salience of reward allocation norms

In a dyadic bargaining situation there is considerable evidence that the alternative outcomes of the bargainers (if they cannot reach agreement) have important effects on bargaining outcomes. Under the assumption that situational factors affect the nature of the relation between the alternatives of the bargainers and bargaining outcomes, the effects of two factors were assessed: the relative size of the reward to be negotiated (excess of prize minus alternatives) and the magnitude of the difference in the alternatives of the two bargainers. Using college students as subjects, the predictions of two models were also contrasted: the equal excess model and Shapley-w. The relative size of the prize did not have a significant effect on the accuracy of the two models, but the magnitude of the difference in alternatives had marked effects. The results also suggest that the Shapley-w model may be more accurate when the bargainers are relatively inexperienced and cooperatively oriented, whereas the equal excess model may be more accurate when the bargainers are relatively sophisticated and competitively oriented.     

Breakdowns in flexible use of information: Intelligence-related differences in transfer following equivalent learning performance

Groups of retarded and nonretarded children were investigated as they learned three rules underlying problems adapted from the Raven Progressive Matrices Test: rotation, imposition, and subtration. The interest was in evaluating group differences in the ease with which the original set of rules was learned and the flexibility with which these rules were transferred to modified contexts. In the case of either learning or transfer, the metric of performance was the amount of aid, specifically the number of computer-generated graduated hints, needed for each subject to solve the problems. The groups were matched on their entering competence to deal with the rules under scrutiny, and also on mental age. No group differences were obtained as the subjects learned the original set of rules. However, on subsequent occasions when required to make flexible use of those rules, clear group differences emerged; and those differences increased as the similarity of the training and test contexts decreased. The results were seen as consistent with theories that emphasize transfer flexibility as one potential source of individual and comparative differences in intelligence.     

Effects of alternatives in coalition bargaining

A critical factor in bargaining and coalition formation is the alternative outcomes of the bargainers if an agreement cannot be reached. In some situations bargainers have individual alternatives while in other situations their alternatives must be negotiated with others. The purpose of this study was to contrast the effects of one-person and two-person alternatives on coalition outcomes. The second purpose of the study was to contrast the predictions of four theories of coalition formation: bargaining theory, equal excess model, Shapley value, and a special case of equity theory. The results indicate that one-person alternatives enhance the bargaining strength of the stronger players more than two-person alternatives. The predictions of the equal excess model and the Shapley value were more accurate than the predictions of bargaining theory and equity theory. However, the greater accuracy of the equal excess model and the Shapley value may be restricted to situations in which the bargainers have one-person rather than two-person alternatives.     

Incidental learning in preschool children as a function of level of cognitive analysis

Preschool children's recall and clustering of organized lists of pictures were examined under deliberate instructions to remember or in incidental learning situations. The incidental tasks either required comprehension (categorization, or a rating of pleasantness-unpleasantness) or were formal orienting tasks involving processing in terms of physical features.Explicit instruction to remember and formal incidental instructions did not differ, and both lead to poorer performance than the comprehension activities. Categorization, whether accompanied by explicit instructions to recall, or occurring in the context of a meaningful activity, was no more efficient than categorization in and for itself. With children as with adults, it is the activity of the children which determines depth of processing and subsequent retention, not the intent to remember per se.     

Maintenance and generalization of trained metamnemonic awareness by educable retarded children

The majority of educable retarded children (young group, MA 6; old group, MA 8) required to estimate their memory span was found to be unrealistic estimators. Following training in span estimation the older subjects improved under both explicit and implicit feedback conditions, while younger children only benefited from explicit feedback. Three posttests of the effects of training revealed long-term (1-year) maintenance of training for older subjects but younger subjects showed post-test improvement only on an immediate test. While long-term maintenance was found for older subjects, generalization to similar span-estimation tests was not found. The utility of training metamnemonic knowledge which does not generalize was questioned and alternate training procedures were proposed.     

Semantic integration in children's reconstruction of narrative sequences

Preschool to fourth grade subjects were required to reconstruct a previously seen logical sequence by selecting old items from a set containing actually seen events and two types of new items, those consistent or inconsistent with the ordered sequence of the story. Older children were more efficient at adopting a consistent choice strategy, at rejecting inconsistent items and at retaining the end-anchor items of the story. When performance on the old anchor items was excluded, however, all grades had difficulty distinguishing the new-consistent items from the actually experienced old items. It is suggested that memory for logical narrative sequences involves the retention of the gist or theme in an integrated unified representation of the meaning rather than a series of discrete events. Further, the underlying processes of integration and inference are stable across ages.     

Comparative validity of traditional versus S-R format inventories of interpersonal behavior

The comparative validity of two “S-R format” inventories of interpersonal behavior, Kinnane et al.'s (1969) Schedule of Interpersonal Response and a newly developed Rational S-R Inventory, and two “traditional” inventories, the Personality Research Form and the Interpersonal Check List, was examined with respect to 14 self-report and peer rating criteria selected to broadly tap the interpersonal domain. Sixty-four male and female high school seniors served as Ss.In spite of the situational specificity inherent in the S-R inventories, the traditional inventories substantially outperformed the S-R inventories and, in contrast to previous findings, also outperformed simple self-ratings. The results are discussed not only in terms of the relative advantages of various inventory construction strategies but also in reference to the problem of criterion measurement and theoretical and methodological issues in the assessment of situational parameters.
