Developmental and individual differences in the use of the control-of-variables strategy.

48 6th and 8th graders were given 2 successive presentations of a standard Piagetian control-of-variables (COV) task. Between the 2 presentations, Ss in 4 conditions took part in an activity designed to elicit the COV strategy or to serve as a control. In a 2nd session, Ss were administered a different task requiring use of the COV strategy, a task requiring use of a different formal operations scheme (proportionality), and a measure of field independence. For older Ss, strategy use increased equally from the 1st to the 2nd presentation in all 4 conditions; for the younger Ss, strategy use increased only for 2 conditions containing a set of intervening probe questions. At both ages, "spontaneous" (i.e., 1st presentation) COV strategy users outperformed their "latent" (2nd presentation only) peers on all 3 Session 2 tasks. Latent strategy users outperformed strategy-absent Ss on the COV transfer task and on the proportionality task. Data clarify the distinction between spontaneous and latent levels of availability of a formal operations strategy. (19 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Categorization as a preferred memory strategy: Developmental changes during elementary school.

20 2nd, 20 4th, and 20 6th graders (a) judged the relative effectiveness of 4 memory strategies (looking, naming, rehearsing, and categorizing) and (b) studied and recalled sets of stimuli. The order of tasks was counterbalanced within grade. Ss in all grades chose rehearsal and categorization over looking or naming. Second graders in both conditions and 4th graders who did the memory tasks first judged rehearsal and categorization as equally effective. Fourth graders who made strategy judgments first and 6th graders in both conditions significantly preferred categorization over rehearsal. On the memory task, 4th graders who judged strategy effectiveness prior to doing the memory tasks recalled more than those doing the memory task first. There was no difference due to condition for the other 2 grades. Degree of strategic awareness was related to recall only for children who made the strategy judgment prior to doing the memory tasks. Findings illustrate developmental changes in awareness of the relative benefits of categorization over rehearsal during elementary school and suggest that performance on a memory task may be affected by the degree to which appropriate metamemorial awareness is "activated."

Automatic encoding of superordinate and subordinate taxonomic categories in different populations.

Utilized D. D. Wickens's (1970) release from proactive interference (PI) task to assess automatic conceptual encoding at both the superordinate and subordinate category levels in 2 populations. Ss were 2nd and 4th graders from a low-socioeconomic-status Black community and 2nd and 4th graders from a middle-class White community. The principal factors in the study were list (superordinate: animals and foods; Subordinate 1: birds and mammals; Subordinate 2: fruits and vegetables), population, grade level, and condition (control vs shift) as between-Ss factors and trials (1–4) as a within-Ss factor. 48 children from each population and grade level served as Ss for each list. Results indicate significant PI build-up for all Grade?×?Population combinations on the 3 lists, with the exception of the 2nd graders on the superordinate list. Release from PI was observed at the 4th-grade level on the superordinate list and at both grade levels on Subordinate List 1 (birds and mammals). Generally speaking, reliable differences between the 2 populations in PI build-up and/or release were not detected. (18 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Recency judgments in children: A production deficiency in the use of redundant background cues.

Presented 8 20-picture lists to 40 2nd and 40 4th graders, and each list followed by 3 test pairs, each pair repeating 2 list items. Ss were required to pick the item they had seen more recently on the list. Background color cues were provided, and half the Ss were instructed in using the cues to simplify the task. Difficulty of the recency judgments was also varied by increasing the separation between the 1st presentation of the tested items from 3 to 9 items. The wider the separation, the better the judgment of relative recency. On cue problems, training improved the performance of 2nd graders but not 4th graders. The developmental implications of the study are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Retrieving for rehearsal: An analysis of active rehearsal in children's memory.

Two experiments with 96 2nd graders and 24 6th graders explored the operation of retrieval processes in Ss' active rehearsal strategies. Both experiments used free-recall tasks, in which Ss were given instructions in active rehearsal as well as supports that might facilitate the retrieval operation and thus enhance both rehearsal and recall performance. In Exp I, 2nd and 6th graders were given visual or auditory access to an 18-item stimulus-word list. Results show that, by providing 2nd graders with an opportunity to view previously presented words, rehearsal activity and recall increased substantially, whereas the performance of the 6th graders was not affected. In Exp II, presentation time and visual access to a similar 18-word list were manipulated for 2nd graders. Results show that the provision of extra time for an item enabled Ss to execute a more active rehearsal strategy. Extra time had only minimal effects on recall, except when it was combined with visual access to the items. Findings suggest that retrieval per se is not necessary for the beneficial effects of active rehearsal, if other procedures can be followed to permit the juxtaposition of several items in rehearsal.

Factors influencing rule discovery in children.

Reports on 2 studies using the Esper paradigm to determine development of rule application and discovery capabilities. This paradigm employs both learning and generalization phases. In Exp I with 48 3rd and 4th graders, it was determined that Ss could learn and generalize when rule and structure were provided, but there was little evidence of rule discovery. In Exp II with 48 different 3rd and 4th graders, memory and attention manipulations were added. Both manipulations facilitated learning, but only attention facilitated rule discovery. In both studies 4th graders performed better than 3rd graders on generalization but not learning. The relationship between performance on the Esper and Raven Coloured Progressive Matrices (given to all Ss), although inconsistent, when covaried out removed the significant grade but not experimental effects.

Cognitive dimensions of numerical rule induction.

Studied the cognitive determinants of number analogy performance by systematically manipulating the processing demands imposed by the items. To explore sources of developmental differences in analogical reasoning, Ss were included from 2 age levels—36 4th and 5th graders, and 18 undergraduates. To allow the investigation of individual differences in reasoning ability, the 4th and 5th graders were selected to represent 2 general aptitude levels, average and high IQs (as measured by the Stanford-Binet Intelligence Scale and the Otis-Lennon Mental Ability Test). All Ss were administered the Number Relations subtest of the Analysis of Learning Potential and the WAIS. In each group, a combination of process and content knowledge factors accounted for more than 70% of the variance in item solution difficulty. The most critical processing demand affecting successful performance was the amount of solution-related information to be assembled and managed in working memory. Process and content-knowledge factors differentiated adults from children, whereas only specific, factual knowledge competencies seemed to differentiate between IQ levels in children.

Children's use of the discounting principle: A perceptual approach.

Introduced a perceptual analog technique in a developmental investigation of the discounting principle. In Exp I, 60 kindergartners, 2nd and 4th graders, and college students watched animated films depicting the simultaneous movements of 2 triangles toward a goal—one that was pushed by an external object (facilitative cause present) and one that was not (facilitative cause absent). Although undergraduates understood the discounting principle, the younger Ss did not. However, because many children (mis)interpreted the "push" as an aversive stimulus, a 2nd experiment illustrated a sequence in which 1 of 2 triangles was "carried" toward a goal. For this version, 80 kindergartners; 2nd, 4th, and 6th graders; and college students all made the discounting-consistent choice, and kindergartners tended to do the same. Age differences emerged only in Ss ability to explain their responses. The development of a multiple sufficient cause schema and the animated film technique are discussed.

Children's attributions for failure and success in different aspects of reading.

Investigated the attributions of 82 3rd graders and 82 6th graders for their success and failure in different reading situations with an extended set of causes (as a function of age and achievement differences). Ss were split into good and poor readers on the basis of a median split on the Reading Comprehension subtest of the California Test of Basic Skills. Ss reading achievement was then assessed in 2 reading situations (evaluation of reading performance and reading for meaning). Ss were asked to rate the degree to which each of 6 causes (ability, paying attention, studying, luck, task difficulty, and assistance from others) was responsible for their success or failure. Findings show that 6th graders' locus of control scores varied across situations, while 3rd graders' scores did not. Studying and paying attention were salient to Ss as causes. Age and achievement interacted, with low-achieving 3rd graders giving higher ratings to causes more clearly beyond their control than high-achieving 3rd graders, whereas low- and high-achieving 6th graders did not differ.

Development of children's use of a story schema to retrieve information.

In Exp I, 80 2nd and 6th graders and 40 college students heard normal or scrambled stories and either recalled them exactly as heard or recalled them by making them into "good" stories. Scrambled stories generally depressed recall; 2nd graders performed poorly, but there was a clear improvement with age/grade in the ability to reorganize a scrambled story. In Exp II, an explanation for 2nd graders' poor performance was proposed and tested with 24 additional 2nd graders. It was thought that 2nd graders might know the form of an ideal story, but fail to spontaneously and consciously use their knowledge of its constituent parts to guide retrieval. A brief training procedure was introduced to teach a new group of 2nd graders how to sequence story propositions. The expectation was that training would prime them to use the internal story structure as a retrieval strategy when faced with a set of scrambled stories to recall (in good order). The expectation was confirmed. (10 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A note on the evaluation of a new answer form.

An answer form with a new item format proved comparable to a standard IBM form in an answer-marking task. A new red answer form with similar new item format was then used with actual tests. Ss were 4th graders, 8th graders, and 12th graders in 4 cities; each took a test form appropriate for his grade level with a new and old answer form. The new answer form was considered acceptable for use in the 8th grade and higher grades. Color change represented by the new red answer form had no significant effect on test performance of persons in the 8th grade or higher. Statistical analyses of the 4th-grade data proved inconclusive. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Reading, memory, and metacognition.

Investigated relations among reading skills, metareading (knowledge about reading), memory, and metamemory (knowledge about memory) as they relate to reading ability (good vs poor readers), operativity, and grade level. 40 2nd graders (aged 7.25–9.83 yrs) and 40 4th graders (aged 9.42–22.00 yrs) were interviewed to assess the reading–memory variables. Significant but low correlations were obtained between metareading and reading, metamemory and memory, metareading and metamemory, and reading and memory. Significant effects of operativity were revealed on all dependent measures. Operative Ss had higher scores on the metareading and metamemory tasks, read at higher levels, and remembered more items on the memory tasks than did nonoperative Ss. Effects of grade level were revealed on most dependent measures. Fourth-grade Ss received higher scores on the metareading and metamemory tasks and read at higher levels than did 2nd-grade Ss. An interaction between operativity and grade level revealed that operative 2nd-grade and both groups of 4th-grade Ss made fewer total reading errors than did nonoperative 2nd-grade Ss. The effects of operativity, experience, and metacognition on reading and memory skills are discussed. (43 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Use of headings by children for text search.

Examined the development of text search strategies in 144 4th, 6th, and 8th graders who were assigned to reading booklets with or without headings embedded in the reading material. Both younger and older Ss demonstrated evidence of efficient use of headings as locational aids when explicitly instructed on how to use them, and spontaneous use of headings as a search strategy was observed in half of the 4th and 6th graders and in most of the 8th graders. Ss at all levels read faster when asked to search for a specific fact than when asked to read the story line by line, indicating their awareness of when to skim. Findings suggest that by the 4th grade, children may have the cognitive skills to benefit from headings but may use these skills only in structured situations.

Developmental and individual differences in conditional reasoning: The role of contradiction training and cognitive style.

Examined the development of conditional reasoning from the perspective of the competence-moderator-performance approach discussed by W. F. Overton (1985) and Overton and J. L. Newman (1982). The effects of task interpretation and cognitive style as moderator variables for conditional reasoning were examined, using 36 8th-, 36 10th-, and 36 12th-grade male students as Ss. Ss were given an inference task, and half the Ss at each grade level received training with contradictory evidence to alert them to faulty task interpretations. Generalization of training was assessed with a 2nd conditional reasoning task, and cognitive style was assessed with the Matching Familiar Figures Test. Results indicate that only the 12th graders benefited from contradiction training, and this training generalized to the subsequent task. A reflective style enhanced performance at each grade level for the initial task. However, the beneficial effects of a reflective style were restricted on the generalization task to 12th graders who had received contradiction training.

Lexical ambiguity and children's word recognition.

Conducted 2 experiments to examine the word recognition processes of 2nd, 4th, and 6th graders. In Exp I, 72 Ss named target words that were primed by words that had more than 1 meaning. Targets were related either to the more or less frequent sense of the ambiguous prime or were unrelated to it. Findings indicate that older Ss were more likely than younger Ss to restrict processing of ambiguous words to the most frequent meaning. While younger Ss showed approximately equal facilitation for words related to either meaning, regardless of each one's relative frequency, 6th graders apparently retrieved only the most frequent meaning. Exp II, with 36 Ss, was similar to Exp I but included neutral primes and varied the interval between presentation of prime and target. Results show that all groups showed automatic retrieval of both meanings of the ambiguous word. For 6th graders, however, this retrieval was followed by a 2nd stage, in which attention was allocated to the more frequent meaning, maintaining it, while the less frequent meaning was inhibited. Overall data indicate that older children use meaning frequency to narrow the amount of information kept active following word recognition.

Black children's use of nonstandard grammar: Two years later.

A Berko-type task requiring Ss to derive the present, plural, possessive, and time extension forms of nonsense syllables was administered to 115 Black and White 2nd graders and readministered to a subsample of these same children upon their reaching the 4th grade. At both 2nd- and 4th-grade levels, White Ss supplied significantly more standard English responses and Black Ss significantly more hypothesized nonstandard English responses to each of the 4 tasks. Additionally, Ss of both races showed significant increases in standard English usage and significant decreases in nonstandard English usage over the 2-yr period. The possibility that grammatical differences between Black Ss and White Ss might disappear given more time is discussed. (20 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Children's perceptions of friendships as supportive relationships.

Assessed 122 2nd, 4th, 6th, and 8th graders' perceptions of the social support provided by friends. During individual interviews, Ss were asked about the frequency of emotional support or intimate self-disclosure, tangible support or prosocial behavior, and other types of support provided by a particular friend. Ss were also asked about the frequency of conflicts with the friend and the frequency of supportive interactions and conflicts with a classmate who was only an acquaintance. Factor analyses revealed an increase with grade in the differentiation between the support and conflict dimensions of friendship and acquaintanceship. At all grades, Ss perceived friends as more supportive than acquaintances, but explanations for the lack of support from acquaintances changed with grade. Sixth graders often gave personal attributions (e.g., saying that the acquaintances were selfish or hostile). Eighth graders favored more situational attributions (e.g., saying that they had few supportive interactions with acquaintances because they rarely came in contact with them). The potential value of perceived-support measures in research on the consequences of friendship is discussed. (27 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Need for achievement in Negro and white children.

2 studies were done comparing the scores of Negro and white children on need for achievement (n Ach), defined as concern with achieving high standards of excellence. All Ss were from rural, central North Carolina. In the 1st study, 5th and 7th graders wrote stories in response to 6 line drawings of people. In the 2nd study, 3rd-, 5th-, and 7th-grade Ss and high-school Ss wrote or told stories to 12 other line drawings. In both studies, white Ss scored significantly higher than Negro Ss, and n Ach scores increased significantly with age. In the 2nd study, Negro girls scored significantly higher than Negro boys. Negro Ss had more hostile non-n-Ach themes in the 1st study, but there was no meaningful pattern of the non-n-Ach themes in the 2nd study. (21 ref.)

Development of selective attention during visual search.

Monitored eye movements in 8 2nd graders, 8 6th graders, and 8 college students during a search task in which Ss were given different types of information about target location before trial onset. Whereas color cues facilitated search performance in the 2 older groups, form cues were less successful in facilitating search and significantly interfered with search relative to a control condition for the 2nd graders. Both facilitation and interference effects in overall search times were related to number of fixations rather than to average fixation during a trial.

Children's concurrent use of rehearsal and organizational strategies.

This study examined whether children could benefit from the simultaneous use of two mnemonic strategies. In Experiment 1, 3rd and 6th graders were taught to use the rehearsal and organizational strategies of same- or different-aged peers. At both ages, Ss who used developmentally advanced techniques recalled more than those who sorted and rehearsed like younger children; moreover, use of both efficient strategies together increased recall additively. In Experiment 2, 3rd graders rehearsed in any way they wished while learning taxonomically related or unrelated items. With each type of materials, 4 groups differed in whether the items were left visible, in whether Ss were asked to sort, and, if so, in whether they were instructed to sort to "help them remember" or on the basis of meaning. Those Ss instructed to sort showed higher recall and more active rehearsal, regardless of type of sort instructions or items. Thus, the use of one strategy may elicit effective use of another.
