Children's metacognition: Exploring relations among knowledge,process, and motivational variables

Following a metamemory pretest, 60 first and third grade children (6 and 8 years of age, respectively) were divided into three treatment groups which received task-specific strategy instructions appropriate for three memory problems, general metacognitive information about subordinate and superordinate processing, or both strategy and metacognitive training. Maintenance and generalization versions of the memory tasks were given, followed by an attributional assessment of children's perceptions of the causes for specific success and failure outcomes. Post-training scores on the memory tasks showed that strategy training was highly successful. Metacognitive training appeared to have no effect on the metameory or strategy scores with one exception: metamemory and strategy use on the generalization task were significantly correlated only for children who received both metacognitive and strategy training. Apparently, children who were initially high in metamemory skills profited more from the comprehensive training package, using new metacognitive insights to aid the generalization of acquired strategies to the transfer tasks. Among strategy-trained children those who attributed success to effort were both more strategic and higher in metamemory than those who attributed task outcomes to noncontrollable factors such as ability or task characteristics. Results were discussed in terms of the interactive nature of knowledge, process, and motivational variables as determinants of strategy transfer.     

The use of conditional probabilities in applications of Holland's theory

The hexagon of J. L. Holland (1973, Making Vocational Choices: A Theory of Careers, Englewood Cliffs, NJ, Prentice-Hall) is a useful heuristic device for predicting congruency and consistency among the six personality/environment types specified by his theory. One limitation of the traditional hexagon is the implicit bidirectionality: the hexagon displays a single distance between two types. People in applied areas may assume a symmetry which does not exist. Examples are given of situations in which a consistent asymmetry occurs; e.g., in the illustrative data presented, C (Conventional) types are more likely to have E (Enterprising) as a secondary interest than E types are to have C as a secondary interest. Implications of such asymmetries are discussed and suggestions made concerning counseling and other applications.     

Age and gender differences in solutions to hypothetical social problems

One hundred and twenty preschoolers and 77 kindergartners individually were administered a measure of social problem-solving. This measure consisted of five stories in which a protogonist sought to acquire an object from a same- or different-age or same- or different-sex target. Age differences in the numbers and types of strategies were few. However, kindergarteners showed greater flexibility in strategy sequencing. Prosocial strategies were more often directed to older targets; agonistic strategies were more often directed to younger targets. Girls suggested more prosocial strategies when girls sought an object from bay targets. Given the results it is suggested that flexibility is social problem-solving and attention to target characteristics should be included in future social problem solving training programs.     

Spatial cognition: gathering strategies used by preschool children

How preschool children retrieve hidden objects was examined in two cross-sectional studies. The first was a simple task in which 1- and 3-year-olds saw two treats hidden in their living room. The newly walking infants generally sought the closer treat first, providing evidence for a least-distance spatial strategy. However, this strategy was affected by a tendency to approach the hiding place most recently baited. Three-year-old children used a least-distance strategy regardless of the order of hidings. In Experiment 2, 3- and 5-year-olds saw 12 puzzle pieces hidden in various containers equally spaced within a naturally furnished children's laboratory. Factors in addition to age were the distinctiveness of the containers and a requirement to return to the center of the array after each retrieval. Overall, children of both age groups were quite successful at this task, retrieving 11 of the pieces. However, 3-year-olds were less efficient, retrieving fewer pieces and requiring more searches. Detailed analyses of errors and patterns of choices indicated differential processes in achieving their performance. Three-year-old children showed the use of memories for events, discrimination of classes of hiding places, and efficient spatial biases. Five-year-old children were more likely to exhibit these processes concurrently.     

Therapy for helpless monkeys

During the course of pilot studies and two formal experiments examining the learned-helplessness phenomenon in rhesus monkeys, 5 subjects failed to escape in a shuttlebox following earlier experience with aversive stimulation in primate-restraining chairs. The present report details a therapeutic manipulation designed to reverse these subjects' maladaptive behavior in the shuttlebox. Introduction of a different fear stimulus (a net previously used to restrain the animals) was found to be effective in inducing shuttlebox escape and avoidance learning. The implications of the present findings for an understanding of the learned-helplessness phenomenon and their relevance to therapy for human depression are discussed.     

Place versus response as the basis of spatial errors made by young infants

Nine-month-old infants search successfully for an object which they have seen hidden in one position, but they frequently continue to search for it there after observing it being hidden in a new position. This error can be explained in terms either of egocentric response perseveration or of perseveration to a particular place in space. In order to distinguish between these hypotheses, 80 infants were presented with a problem consisting of several different conditions which separated response, position on a table, and absolute spatial position as factors leading to errors in search for hidden objects. The results strongly support the egocentric response hypothesis. The reason for this response perseveration strategy is discussed in terms of the lack of active experience of spatial displacements among 9-month-old infants.     

A reexamination of the faithful subject role

Fillenbaum (Journal of Personality and Social Psychology, 1966, 4, 532–537; Fillenbaum & Frey, Journal of Personality, 1970, 38, 43–51) has proposed that a relatively large number of subjects within certain experiments will adopt a faithful subject role, that is, they will intentionally avoid basing their behavior on any suspicions they may have regarding the experimenter's hypothesis. However, examination of the studies on which this conclusion was based casts doubt on whether Fillenbaum's subjects were truly faithful or whether they may have become aware of the nature of the deception after all opportunity for awareness to influence their responses had passed. To test this hypothesis, awareness measures were administered to subjects either before they took an incidental learning test or (as in Fillenbaum's studies) after the test. As predicted, fewer subjects were classified as faithful in the first condition than in the second. It was concluded that, in fact, very few if any subjects are actively faithful. Discussion also concerned the problems associated with role analyses of subject behavior.     

Therapist-controlled exposure in vivo versus self-controlled exposure in vivo: A comparison with obsessive-compulsive patients

Fourteen obsessive-compulsive clients were given treatment consisting of ten sessions of gradual exposure in vivo With half the clients, the exposure in vivo was therapist-controlled; with the other half, the exposure in vivo was self-controlled.

The results of the posttest showed that both versions of the treatment resulted in a significant improvement on the in vivo measurement, anxiety and avoidance scales, Leyton Obsessional Inventory, Self-Rating Depression Scale and anxious mood. Neither the posttest nor the follow-ups one month and 3.5 months later indicated a difference between the effects of the two conditions. Self-controlled exposure in vivo proved to be as effective as therapist-controlled exposure in vivo, in spite of the fact that in the latter condition each treatment session lasted twice as long as in the former condition.     

Loss of control by a less valid or by a less salient stimulus compounded with a better predictor of reinforcement

An unsalient stimulus, or one imperfectly correlated with reinforcement, may acquire significant control over responding, provided that it is the only available signal for reinforcement, but may fail to acquire control if it is reinforced only in conjunction with a second, more salient or more valid stimulus. A stimulus imperfectly correlated with reinforcement may also lose control over responding if having initially been reinforced in isolation, it is subsequently reinforced only in conjunction with another, more valid stimulus. If the effects of relative salience are to be explained in exactly the same way as those of relative validity, we should expect a similar loss of control by an unsalient stimulus, A, if, after initial consistently reinforced trials to A alone, subjects subsequently receive reinforcement only in the presence of a compound stimulus, A + B. Two experiments on discrete-trial discrimination learning in pigeons and one on conditioned suppression in rats confirm this expectation. The results have implications for theories of selective association in conditioning and discrimination learning.     

Short-term memory and information processing in pigeons

Six pigeons were trained to asymptotic performance on a variable-delay matching-to-sample task in which the samples were sometimes line or color elements and sometimes line-color compounds. On compound-sample trials, the comparison stimuli were sometimes color elements and sometimes line-tilts. Sample type and delay (0, 1.5, and 4.5 sec) were varied within sessions, and sample duration (.4, 1.0, and 3.0 sec) was varied between sessions. Forgetting curves were steeper for line-tilt than for color. As sample duration increased, matching performance improved more for colors than for line-tilts, especially at delays greater than zero. Performance was better with element samples than with compound samples only on the line-tilt dimension at zero delay. Some predictions of a unitary trace growth and decay theory of pigeon short-term memory were not confirmed. A dual-code hypothesis was proposed to account for the data.
