Psychological studies of children who have cancer

Increasingly, more optimistic prognoses for children who have cancer have led investigators to study the adjustment reactions of children who survive this traumatic experience. There is considerable evidence that the experience of having cancer, receiving prolonged and often painful treatment, and the uncertain condition of cancer survivorship have profound emotional effects on children. The characteristic features of the psychological impact of cancer are the experience of continuing uncertainty in a life-threatening crisis and the resultant search for meaning. Studies are beginning to find that even very young children actively struggle to organize and make sence of this experience.     

The development of analogical reasoning processes.

Two experiments were conducted to test the generalizability to children of a theory of analogical reasoning processes originally proposed for adults (R. J. Sternberg, Psychological Review, 1977a, 84, 353–378; R. J. Sternberg, Intelligence, information processing, and analogical reasoning: The componential analysis of human abilities, Hillsdale, N.J.: Lawrence Erlbaum Associates, 1977b) and to examine the development of analogical reasoning processes in terms of five proposed sources of cognitive development: (a) availability of component operations; (b) strategy for combining multiple component operation; (c) strategy for combining multiple executions of the same component operation; (d) consistency in use of strategy; (e) component-operation latency and difficulty. Between 15 and 21 subjects in each of grades 2, 4, 6, and adulthood (ages 8, 10, 12, and 19 years, respectively) were tested in their ability to solve analogies of systematically varied difficulty. Performance was measured in terms of latencies for items solved correctly, latencies for all items solved, and error rates. A slightly modified version of the Stenberg, 1977(a), Stenberg, 1977(b) theory was found to be applicable to the data for each of the age levels tested. In analogies with perceptually separable attributes, change over age was found in sources (d) and (e) noted above. In analogies with perceptually integral attributes, change over age was found in sources (a), (c), (d), and (e). Developmental trends were discussed in terms of past theory and findings, and possible reasons for differences in developmental patterns between the two kinds of analogies were suggested.     

Thematic elaboration and proximity in childrens recall, organization, and long-term retention of pictorial materials.

Preschool and fifth-grade children were asked to learn and recall lists of nine pictures of common objects in which the thematic relationship and the physical proximity of subsets of items were varied. Five presentation conditions (lists) were employed: (1) subgroups of three items simultaneously presented with an explicit theme, (2) the same items as in (1) but randomly arranged in the subset, (3) unrelated items presented simultaneously in groups of three, (4) nine items presented successively but temporally blocked in subgroups of three, and (5) nine items displayed successively in a random arrangement. Recall and clustering scores indicated that the older children spontaneously elaborated pictures when subsets of items were presented simultaneously and when these items formed a natural theme. The preschool children failed to elaborate, responding more on the basis of the proximity of the items. Proximity was a potent recall cue for both age groups. Long-term tests, carried out after one week, showed good retention, the output organization of which closely paralleled that observed during original learning.     

Effectiveness of a brief counseling intervention in stimulating vocational exploration

The intervention procedures used in this study, a brief report of vocational interest scores and small group sessions on vocational planning, were designed to encourage girls to consider the full range of occupations, unrestricted by sex-role stereotypes. In each of three schools, ninth-grade girls with average academic ability or above were randomly assigned to an intervention group (N = 195) and a control group (N = 195). Analyses of 1- and 3-month outcome data indicated that the intervention stimulated occupational exploration and increased congruence between occupational preferences and measured interests. Outcomes differed according to interest type, thus suggesting that certain students may need more counselor attention than others.     

The cognitive and neurological basis of developmental dyslexia: a theoretical framework and review.

It is argued that developmental dyslexics have difficulty in accessing the meaning of written words via phonological recoding, although they can successfully access meaning by a direct visual route. This difficulty with phonological recording is explained in terms of a short-term memory deficit. It is suggested that developmental dyslexia is a genetically-based dysfunction of the inferior parietal lobule and evidence is reviewed that this region is important in both reading and short-term memory. Implications for remedial instruction are discussed.     

Semantic and acoustic processing in free and cued recall by educable mentally retarded adolescents

The abilities of educable mentally retarded adolescents to encode and retrieve words with semantic and acoustic cues were investigated in a free and cued recall task. On each of three trial blocks, seven groups of subjects were presented 20 unrelated stimulus words. Groups received either semantic, acoustic, or no encoding cues along with the stimuli. Free recall was requested from all subjects, followed immediately by a second period of either free recall or cued recall with the semantic or acoustic cues. Semantic cues were most effective when presented both at encoding and retrieval. The subjects were unable to use acoustic information as effective retrieval aids. Results were discussed in terms of encoding dimension dominance and mediational deficiencies.     

The motive to avoid success: A further examination

Horner's (1968) “fear of success” study was replicated and expanded. One hundred seventy-seven high school (HS) and college students wrote stories in response to the following cues: “After first-term finals, John (Anne) finds himself (herself) at the top of his (her) medical-school class.” Results indicated similarity of response of HS men, HS women, and college men, all of whom expressed more fear of success imagery in response to the Anne cue than to the John cue. College women did not conform to this pattern.     

A comparison of error based and time based learning measures as predictors of general intelligence

Two methodological issues involved in determining the relationship between learning and general intelligence (g) are examined. They are firstly, the use of subject learning strategies in a paired-associated learning task and secondly the importance of time in the measurement of learning efficiency. Concerning the first issue, paired-associates learning scores of subjects who were instructed in the use of an appropriate learning strategy correlated significantly with general intelligence scores while those not so instructed did not. Concerning the second issue, a time based learning measure was developed to predice the time required for complete learning in the paired-associates learning task. This measure was compared learning with a number of error-based learning measures in their ability to predict general intelligence. The time based learning measure was clearly superior to the error based measures yielding a correlation of .59 with general intelligence.     

Measures of timed performance and intelligence

The question of an association between IQ and measures of timed performance derived from inspection time and reaction time was examined in a sample of 182 adults and by reanalyzing data involving 48 adults from a previously published study. Multiple regression analysis found that measures of timed performance accounted for as much as 25% of IQ variance in the normal population, but that the inclusion of borderline and mildly retarded subjects resulted in much higher correlation coefficients because of the markedly less efficient performance of these persons in tasks of this kind. This outcome raised doubts about the validity of combining data from retarded and nonretarded subjects. Results ran counter to claims that tasks of the kind used are largely uninfluenced by cognitive variables, so that findings are not necessarily explained satisfactorily in terms of a mental speed factor. It was concluded that these measures of timed performance do not, at this time, provide a basis from which a reliable culture-fair measure of intelligence might be devised.
