The problem-solving strategies of kindergarten and first-grade children during discrimination learning

Kindergarten and first-grade children (6 and 7 years of age, respectively) were given specially designed discrimination tasks with introtact probes preceding each trial. One group (CON) was given the criterion task without prior training. A second group (LTL) received three pretraining tasks of the same type as the criterion task. A third group (HYP) received the same pretraining tasks, but with explicit instructions designed to teach a simple hypothesis-testing strategy. Several indices, designed to reflect the use of win-stay and lose-shift rules, as well as memory for disconfirmed hypotheses, were computed from the protocols of the criterion task. The indices for Group CON suggested that most of these children were using a guessing strategy that involved quite frequent changes in hypotheses. Moreover, many of these children restricted their hypotheses to the irrelevant cues. The indices for Group LTL revealed a spontaneous use of the hypothesis-testing strategy by nearly half of the children. The results for Group HYP indicated that over four-fifths of these children became highly efficient in the use of the problem-solving strategy.     

Why good job performance may (not) be rewarded: Sex Factors and Career Development

An experiment tested the effects of three sex variables on managerial career evaluations. The variables were sex of evaluator, sex of manager (evaluatee), and predominate sex of manager's subordinates. Each subject evaluated four managers, one in each possible combination of the last two independent variables, in an “in basket” format. All four situations included comparable managerial performance data. Subjects evaluated each manager in terms of size of a deserved salary increase, probable performance if promoted, promotability, and probability of attaining 5-year tenure. There were no differences in evaluations between male and female evaluators. Manager's sex and predominate subordinate sex frequently interacted. The interactions were interpreted as a sex-matching bias which can inappropriately benefit managers of opposite sex subordinates and hinder careers of managers with subordinates of their own sex.     

Dissociations of language function in dementia: A case study

In this report we describe and attempt to characterize the deterioration in semantic knowledge occurring in a victim of a progressive dementing disease. The subject was unable to match even highly familiar naming words with their actual or pictured referents; instead, she consistently overextended verbal labels to closely associated distractors. The alteration in scope of referential meanings suggested by this overextension effect was apparently related to a breakdown in the structure of underlying categories. On a nonverbal match-to-sample procedure, for example, dogs were treated as exemplars of the cat family. Evidence for the breakdown of semantic knowledge was not limited to picture labeling paradigms. Thus, we found that the subject was unable to utilize semantic context in the written disambiguation of spoken homophones but could, at the same time, use even minimal syntactic cues as the basis for proper lexical selection. This last result was consistent with other lines of evidence pointing to the relative preservation of syntactic operations, in marked contrast to the semantic loss. The importance of this dissociation of function in organic pathology is considered from a number of perspectives, including its relevance to models of language organization in the brain.     

Stage order and dominance in adolescent vocational decision-making processes: An empirical test of the Tiedeman-O'Hara paradigm

Multidimensional scaling procedures were applied to checklist measures of stages from O. V. Tiedeman and R. P. O'Hara Career development: Choice and adjustment, New York: College Entrance Examination Board, 1963, vocational decision-making paradigm. Responses from two high-school samples were analyzed in order to test the hypotheses that stages are ordered as theory predicted and that stages represent dominant psychological states. The stage order hypothesis was essentially supported by findings from scaling solutions applied to two 11th-grade and one ninth-grade sample. The important exception was that the last two stages were reversed. Apparently grade level was not the dimension on which stages unfolded. The stage dominance hypothesis was not supported by the evidence. Student responses were not predominantly associated with a single stage but rather were distributed over several stages. Both results were interpreted in terms of the theory and the instruments. A second conclusion was that metric unfolding is a useful method for analyzing cross-sectional data bearing on construct validity for ordered stage constructs.     

Hyperlexia as a variant of developmental language disorder

Memory and associative reasoning skills of 10 hyperlexic children are examined. The results suggest superior visual and isolated auditory memory skills along with impaired associative language ability. The results are discussed in relation to various theories of hyperlexia.     

Development: Compared to what?: Contrast effects in age-comparative paradigms

Recent controversies about judgment competence of preschool and adolescent children are considered as being a possible product of contrast effects. That is, perceived abilities of children of a given age group may depend on the ages of the other subjects in the experiment. An experiment was done to test the possibility of contrast effects in age-comparative experiments. One group of subjects read about three experimental tasks in which 6-year-old children performed better than 4-year-olds. A second group read about 6-year-olds performing worse than 8-year-olds on the same tasks. Performance levels of 6-year-olds were the same on the two forms. For each task subjects rated the competence of each of the two age groups on the task and predicted the performance of the two groups on a related task. Undergraduate subjects' competence ratings and predictions were higher for 6-year-olds when compared to 4-year-olds than when compared to 8-year-olds. Psychology graduate students showed the same contrast effect for predictions but not for competence ratings. The results are discussed in terms of potential biases in age-comparative methods in developmental psychology.     

The Home Observation for Measurement of the Environment: A comment on Elardo and Bradley's review

The published and unpublished research pertaining to Caldwell's Home Observation for Measurement of the Environment (HOME) inventory was recently reviewed by R. Elardo and R. H. Bradley (Developmental Review, 1981, 1, 113–145). Their review was unfortunately deficient in a number of respects. For example, certain methodological issues bearing on the interpretation of the available data were either unrecognized or dismissed without adequate consideration. In addition, some of the data in the studies cited which contradicted or clouded their conclusions were omitted. An extension and reanalysis of the conclusions reached by Elardo and Bradley in light of recently published studies which were not included in their review, and data not discussed in the studies which were reviewed, is provided. Methodological problems are highlighted, and directions for future research are suggested.
