The use of the cumulative rehearsal strategy: A developmental study

This study was designed to address two issues: (1) At what age do children spontaneously use a cumulative rehearsal strategy; and (2) What effect does the use of the strategy have on their performance?Twenty-eight children at each of five grade levels (nursery, kindergarten, 1, 3, and 5) were tested in a serial-position recall task. Stimuli were pictures of common objects and animals whose labels were one or two syllables in length. Following testing, the children were asked to report the memory strategy they had used.The assumption was made that children who were using a cumulative rehearsal strategy would perform better on series of one-syllable items than on series of two-syllable items. As predicted, nursery, kindergarten, and first-grade subjects correctly recalled as many two-syllable as one-syllable items: Both third- and fifth-graders recalled significantly more one-syllable than two-syllable items. Results indicated that (1) young children do not spontaneously use a cumulative rehearsal strategy until after first grade, and (2) the use of rehearsal did not facilitate overall performance of the rehearsers relative to the nonrehearsers at any grade level. Results are discussed in terms of their theoretical implications for the study of memory development.     

The development of cognitive mapping of the large-scale environment

Two experiments were conducted to investigate the development of children's cognitive maps of large-scale environments. Kindergarten (Mean Age = 5?7), second (Mean Age = 7?7), and fifth (Mean Age = 10?7) graders walked through a large model town and were then required to construct the layout of building in that model from memory. Accuracy of construction increased as a function both of developmental level and repeated encounters with the layout. In Experiment 1, the separate effects of repeatedly walking through the town and repeatedly constructing it both increased the accuracy of the children's reconstructions. In Experiment 2, walking through the environment was no more effective than merely viewing it repeatedly. Young children's accuracy in bounded space (Experiment 1) was far more accurate than their performance in unbounded space (Experiment 2), while older children's accuracy was relatively unaffected by this variable.     

Two components of need for approval score and their relationship to cheating following success and failure

Subjects completed a simulated “intelligence test” on which they were given bogus feedback indicating that they had either met college norms or had failed substantially to meet norms. Immediately following was a period in which subjects could modify their scores and believe that their modification would go undetected. The relationship of need for approval to “cheating” and amount of “cheating” was analyzed. The results supported an “avoidance” interpretation of approval motivation. Two separate components of need for approval score were identified and found to be differentially related to avoidance behavior for men and for women.     

Orienting versus learning instructions in children's free recall: New evidence

Ninety-six first graders were given a list of either words or pictures to process under three types of incidental orienting instructions (semantic, directed at list organization; semantic, directed at individual item characteristics; and physical) and an intentional-learning instruction. For pictures and words, list organizational instructions were the most effective, and were superior to intentional-learning instructions. In contrast, individual item-orienting instructions were not better than intentional-learning instructions on either list. Additionally, different patterns of instructional effects emerged on the two list types, which were interpreted with respect to both available data and contemporary processing theories.     

Children's cued recall: Developmental differences in retrieval operations

Second and fifth grade children were aurally presented a study list containing eight target items plus primacy and recency buffers, followed first by free recall, then by cued recall for items not produced in free recall. Two additional buffer items were used at Grade 5 in an effort to equate the two age groups in free recall of targets. The cues were either of high or of moderate associative strength, and equal for the two age groups. Free recall of targets did not differ with age, suggesting equivalent storage of targets. At Grade 2 the cued recall level matched expectations based on a simple associative account of cuing effects. However, cued recall at Grade 5 was much higher than the normative association values, implicating strategic retrieval operations, the possible nature of which was discussed.     

Children's use of perceptual set

The effects of perceptual set and of “sequential visual noise” on the identification of briefly exposed pictures were examined in 5-year-olds, 8-year-olds, and adults. Subjects were asked to indicate whether a brief target matched a standard. The standard picture was presented either before the target picture (to establish a set) or after the target. The target was presented either alone or last in a series of six brief pictures (i.e., in noise). Adults and 8-year-olds were at ceiling when the target was presented alone, but set facilitated their identification of the target in noise. The 5-year-olds benefited from set both when the target was presented alone and when it was presented in noise. These findings suggest that set for a specific target picture functions similarly at all ages.     

Developmental changes in incidental memory as a function of processing level,congruity, and repetition

Second-, fifth-, and ninth-grade students (8, 11, and 14 years of age, respectively) answered acoustic and semantic questions about words which were either congruent or incongruent with the questions. Subsequently, students' free recall of the words was unexpectedly tested. For words presented once in the list, only orienting task and congruity main effects were found. For twice-presented words, grade level interacted with both variables in that older students' recall was better than younger students' only for semantically encoded, congruent words. This finding is consistant with the hypothesis that developmental increases in semantic knowledge enhance the potential for encoding elaboration, but is in apparent conflict with the results of M. F. Geis and D. M. Hall (Child Development, 1978, 49, 857–861) who found no such interaction for second- and fifth-grade children. The different age spans included in the two studies provides one resolution of the discrepancy in results. However, a second experiment tested the importance of a procedural difference between the two studies. M. F. Geis and D. M. Hall (Journal of Experimental Child Psychology, 1976, 22, 58–66; 1978) presented the question after the stimulus word while we presented the question before the word. For ninth-grade students, the question after condition resulted in an attenuation of the recall difference between semantic and acoustic questions compared to the question before condition. It was argued that the pattern of developmental differences in incidental memory that is obtained may be related to which procedure is utilized.     

A comparison of Holland's model using constructs measured by two different methods

The relationship was studied between the set of constructs specified by Holland's 1973 theory (viz, Realistic, Intellectual, Artistic, Social, Enterprising, and Conventional) measured by an Adjective List (AL) derived from Holland's theory and the same set of constructs as measured by the Vocational Preference Inventory (VPI). The correspondence of the two measures of Holland's model compared the distances between the constructs as measured by the AL and the constructs measured by the VPI in factor space using an adaptation of a model testing procedure reported by Wakefield and Doughtie 1973. The subjects were 174 undergraduates at a state university. The correspondence between the two separate measures of Holland's model was significant (p < .01). These results provide further support of the construct validity of Holland's theory and offer evidence that the relationships hypothesized by the theory are not tied to any one particular method of measurement.     

Reward behavior by male and female leaders: A causal inference analysis

This research investigated causal inferences between leader reward behavior (positive and punitive) and subordinate goal attainment, absenteeism, and work satisfaction over a 3-month period in a merchandise distribution center (n = 252). Four groups were studied: (a) male supervisors-male subordinates, (b) male supervisors-female subordinates, (c) female supervisors-female subordinates, and (d) female supervisors-male subordinates. Using the techniques of tests of mean differences and corrected cross-lag correlations, the results revealed that: (a) No significant differences attributed to sex were found between the four groups with the perceptions of leader reward behavior or subordinate outcome measures, and (b) the causal inference analysis suggested that the relationships between leader reward behavior and subordinate attitudes and behavior were independent of the effects of sex of supervisor or subordinate. Implications for research on sex stereotypes and leadership were discussed.     

Relationships among affective and cognitive factors in humor

One hundred and twenty-five college students rated a total of 74 jokes, chosen by stratified sampling, on funniness and on 13 other scales suggested by humor theories. Highly similar factor structures were found with two sets of jokes. Ratings of surprise, resolution, and originality correlated strongly with funniness and helped define a factor on which funniness ratings loaded. Scales pertaining to painfulness, anxiety, or importance of joke topic were positively correlated with funniness but defined a factor essentially independent of it. Partial correlations suggested that these scales were related to funniness through their common relationship with incongruity and resolution scales. Ratings of how much a joke made subjects “feel free” correlated much more highly with ratings of incongruity and resolution than with ratings of painfulness, anxiety, or importance of joke topic. Results were interpreted as providing support for an incongruity-resolution theory of humor, and for the interdependency of affective factors with incongruity-resolution mechanisms.     

The effects of strategy—Monitoring training on children's selection of effective memory strategies

Second grade children were given training in general principles of strategy monitoring prior to being exposed to differentially effective acquisition strategies in a memory task. The results showed that even though both experimental and placebo control groups could assess when they remembered better, more experimental than control children attributed performance differences to their strategic behavior and then selected the more effective strategy on a forced-choice trial. These findings indicate that instruction in general memory-monitoring principles is sufficient to effect a change in strategy usage. The study therefore provides direct experimental support for the presumed relationship between metacognitive knowledge and subsequent strategy use.     

Facilitating cognitive performance in children: A comparison of strategy modeling and strategy modeling with overt self-verbalization

Children, 3, 4, 5, 6, 8, and 10 years old, were randomly divided into three training conditions—a strategy modeling condition, a strategy modeling with overt self-verbalization condition, and a control condition. The subjects in the two modeling conditions were given training on four cognitive tasks, a signal task, a match-to-standard task, a paired-associates task, and a twenty-questions task. A 6 (age) × 2 (sex) × 3 (treatment) × 2 (trial) analysis of variance was performed on each of the dependent variables associated with each of the four tasks. The results of these analyses indicate that both modeling conditions facilitated performance on the signal and match-to-standard tasks for all six age groups. However, the two modeling procedures facilitated performance on the paired-associates and twenty-questions tasks only in the three older age groups. Since the two modeling procedures did not differ in effectiveness, it was suggested that strategy modeling without overt self-verbalization is the more practical and efficient procedure for facilitating cognitive performance in normal children.     

Spatial visualization and sex differences in quantitative ability

The hypothesis that sex differences in spatial visualization ability might account for sex differences in mathematical ability was supported for a group of 183 male and 81 female college students. With spatial visualization statistically controlled, no significant sex differences in Quantitative Scholastic Aptitude Test (QSAT) scores was found; including sex as a predictor variable increased the variance explained by less than 1%. Although the slope of the regression of mathematics on spatial visualization did not differ as a function of sex, males were somewhat more predictable than females. As the OSAT of both males and females high on spatial visualization was more predictable than the QSAT of those scoring less well, it appears that the sex difference in predictability is due to males having higher spatial ability than females.     

Children's cognitive maps of large-scale spaces: Effects of exploration,direction, and repeated experience

Kindergarteners and third graders (mean ages 5–10 and 8–9 years) repeatedly encountered a model town and then constructed the town from memory. In Experiment 1, the effect of different types of exploration on the development of a cognitive map was assessed. Children who were directed to walk within the town placed buildings more accurately than children who had walked along the town's perimeter. Children who walked within the town and were directed to the spatial relationships among buildings had the highest placement accuracy. Third graders were more accurate than kindergarteners across the three types of exploration. In Experiment 2, children were permitted to explore the town alone for an unlimited amount of time. Under these conditions, third graders still placed buildings more accurately than kindergarteners. A comparison of Experiments 1 and 2 indicated that children developed more accurate cognitive maps when motor activity and attention were directed by the experimenter as opposed to being directed by the child. Accuracy improved with repeated walks and constructions in both experiments, and the results of Experiment 3 suggested that constructing facilitated the development of the cognitive map as much as walking. It was concluded that third graders' cognitive maps were more accurate than kindergarteners' maps due to differences in the speed of acquisition and storage of spatial information.     

Effect of positive,negative, and mixed occupational information on cognitive and affective complexity

A series of concentrated research studies over the past 8 years has significantly demonstrated that cognitive complexity in the vocational realm is positively related to congruence or appropriateness of vocational choice. Moreover, research has shown that introducing occupational information significantly reduces, rather than increases, cognitive complexity. The results of the study reported here relate to changes in cognitive complexity as a function of the type of occupational information introduced, namely, information with respect to the advantages of occupations; the disadvantages of occupations, or a combination of positive and negative features of occupations. Our results clearly demonstrated that while positive occupational information alone leads to greater simplicity, negative or mixed information significantly retards the trend toward greater simplicity. Results are discussed from both theoretical and practical perspectives, especially with reference to the typical occupational information provided in routine vocational counseling.     

Developmental changes in attention-deployment skills

The ability to efficiently allocate attention between two tasks differing in payoff was investigated developmentally. Ten subjects from each of three grade levels (second, fourth, and college) performed an auditory and a visual memory task simultaneously. Modality of the primary task, difficulty of the primary task, and difficulty of the secondary task were varied factorially within subjects. The difference between primary and secondary performances increased with age: All college students, about half of the fourth graders, and none of the second graders showed a meaningful degree of differentiation between primary and secondary tasks.     

Generality of persistence: The role of stimulus and response factors in persistence to punishment

Previous research has shown that intermittent punishment of a response increases its persistence to continuous punishment and that intermittent punishment training in one situation produces persistence to continuous punishment in other situations. Experiment 1 showed that as long as the instrumental response and punishing stimulus were held constant from intermittent to continuous punishment marked differences between these situations had no decremental effect on persistence. Experiment 2 showed that intermittent punishment training of one response resulted in substantial persistence to continuous punishment of a different and apparently incompatible response and that such response change had no more than a marginal effect on persistence. The results were seen as requiring some revision to the traditional conditioning-model interpretation of persistence to punishment.
