Antecedents and consequences of mothers' autonomy support: an experimental investigation.

This study examined the effects of contextual and individual differences on mothers' autonomy support versus control on homeworklike tasks. Sixty mothers and their third-grade children worked on map and poem tasks, with mothers in either an ego-involving (high pressure) or a non-ego-involving (low pressure) condition. Later, children worked on similar tasks themselves. Mothers in the high-pressure condition were more controlling on the poem task. For the map task, mothers who came in with controlling styles and received the high-pressure manipulation were most controlling. Children whose mothers interacted in a more controlling manner wrote less creative poems when alone. Results suggest the importance of context, children's competence levels, and mothers' styles in determining levels of autonomy support.     

Evaluative pressure in mothers: effects of situation, maternal, and child characteristics on autonomy supportive versus controlling behavior

This study examined the effects of situational pressure and maternal characteristics (social contingent self-worth, controlling parenting attitudes) on mothers' autonomy support versus control in the social domain. Sixty 4th-grade children and their mothers worked on a laboratory task in preparation for meeting new children, with mothers in either an evaluation (mothers told their child would be evaluated by other children) or no-evaluation (no mention of evaluation) condition. Mothers in the evaluation condition spent more time giving answers to their children. Mothers with controlling parenting attitudes exhibited more controlling behavior. Further, mothers with high social contingent self-worth in the evaluation condition were most controlling. Results suggest the importance of interactions between situations and maternal characteristics in determining levels of mothers' autonomy support versus control and have implications for helping parents support children's autonomy.     

Effects of cigarette smoking on verbal rote learning and physiological arousal

Abstract.— Verbal rote learning was studied on 12 moderate smokers. In one condition learning was interrupted twice by smoking a nicotine-containing cigarette (Virginia King, 2.1 mg nicotine) and in another condition by smoking a nicotine-free cigarette. Immediately after the first nicotine-containing cigarette there was a drop in the number of correct responses and learning was significantly less rapid under subsequent trials as compared with learning after the first nicotine-free cigarette. After the second cigarette the picture was reversed. Learning was significantly more improved in the nicotine condition than in the nicotine-free condition. Adrenalin excretion increased significantly during learning in both conditions, and heart rate increased significantly after the first nicotine-containing cigarette.     

Effects of two levels of procedural fidelity with constant time delay on children's learning

The purpose of this study was to compare the effects of constant time delay delivered with high procedural fidelity to constant time delay with high procedural fidelity on all variables except delivery of the controlling prompt (i.e., on a mean of 44% of the trials, the controlling prompt was not delivered when it should have been provided). Six preschool children with disabilities were taught to identify photographs in two alternating conditions (e.g., high procedural fidelity and low procedural fidelity). An adapted alternating treatments design was used to evaluate the instructional conditions on the effectiveness and efficiency of instruction. In addition, daily measures were taken of the teacher's implementation of each step of the constant time delay procedures which indicated that the two conditions were implemented as planned. The results indicate that both conditions were effective for four children; for three of these, the high procedural fidelity condition resulted in more efficient learning. For the fifth child, the high-fidelity condition resulted in criterion level responding, but the low fidelity condition did not. However, when the high fidelity procedure and trial-by-trial reinforcement were used for the low-fidelity stimuli, these also were acquired. For the sixth child, neither procedure was effective; thus, the high fidelity condition was used alone and resulted in learning. The results are discussed in terms of using the constant time delay procedure and studying the procedural fidelity of other strategies.     

Comparing and combining retrieval practice and the keyword mnemonic for foreign vocabulary learning

Experiment 1 compared the effectiveness of retrieval practice, the keyword mnemonic and rote rehearsal for learning foreign language vocabulary. Both mnemonic methods produced similar recall and were superior to rote rehearsal. In Experiment 2, participants learned German vocabulary using keywords, retrieval practice or their own method. Retrieval practice and keyword‐based recall were similar and superior to self‐directed study. In Experiment 3, participants studied using keywords, retrieval practice, a combination or an elaboration strategy. Criterion testing occurred immediately and after a week. For receptive learning, retrieval practice and keywords were equally beneficial but for productive learning, retrieval practice was more effective. Combining strategies produced mixed results with significant benefits only for receptive learning in the delayed test. Copyright © 2006 John Wiley & Sons, Ltd.     

External focus of attention and autonomy support have additive benefits for motor performance in children

ObjectivesThe purpose of this study was to examine the combined effects of external focus instructions and autonomy support on motor performance of children. In addition, we sought to provide evidence for an increased focus on the task goal under the external focus condition by using an inattentional blindness manipulation.DesignWithin-participant design.MethodThirty-six children (mean age = 8.5 ± 1.3 years) were asked to perform a bowling task with their dominant hand. Each participant performed 8 trials under external focus (path of the ball), internal focus (hand), or control conditions. In each attentional focus condition, they performed half of the trials under a choice (autonomy support) condition, in which they were able to choose among 4 bowling balls, and a no-choice condition (white ball).ResultsThe external focus instruction resulted in greater bowling accuracy (i.e., more pins knocked down) than internal focus and no instructions (control). Furthermore, choice resulted in more effective performance than no choice. Thus, both factors had additive benefits for performance. There was some evidence for an increased task focus in the external condition.ConclusionsThe present results show that, within the same individuals, instructions to adopt an external focus and the provision of a small choice contributed independently to enhance motor performance in children.     

The Temporal and Dynamic Nature of Self-Regulatory Processes During Independent and Externally Assisted Hypermedia Learning

This study examined the temporal and dynamic nature of students’ self-regulatory processes while learning about the circulatory system with hypermedia. A total of 74 undergraduate students were randomly assigned to 1 of 2 conditions: independent learning or externally assisted learning. Participants in the independent learning condition used a hypermedia environment to learn about the circulatory system on their own, while participants in the externally assisted condition used the same hypermedia environment, but were given prompts and feedback from a human tutor during the session to facilitate their self-regulatory behavior. Previously published pretest–posttest shifts toward more mature understanding of the circulatory system indicate that the externally assisted condition leads to greater learning. The present article uses think-aloud data during learning to explore process issues in light of models of self-regulated learning and conditions of engagement that may affect those processes. Results indicate that access to a human tutor influences the deployment of regulatory processes, intervals of use, and temporal dependencies. For example, there is significantly more planning during the final time interval of the learning session in the externally assisted condition; students in both conditions deploy more learning strategies in the first and second time intervals, compared to the last two time intervals. Additionally, in the externally assisted condition participants were more likely to shift from planning to monitoring and less likely to shift from learning strategies to planning. We discuss theoretical, conceptual, and methodological issues pertaining to these results, as well as implications for future research and the design of adaptive hypermedia systems.     

A theory-based approach to teaching young children about health: A recipe for understanding

The theory-theory account of conceptual development posits that children's concepts are integrated into theories. Concept learning studies have documented the central role that theories play in children's learning of experimenter-defined categories, but have yet to extensively examine complex, real-world concepts such as health. The present study examined whether providing young children with coherent and causally-related information in a theory-based lesson would facilitate their learning about the concept of health. This study used a pre-test/lesson/post-test design, plus a five month follow-up. Children were randomly assigned to one of three conditions: theory (i.e., 20 children received a theory-based lesson); nontheory (i.e., 20 children received a nontheory-based lesson); and control (i.e., 20 children received no lesson). Overall, the results showed that children in the theory condition had a more accurate conception of health than children in the nontheory and control conditions, suggesting the importance of theories in children's learning of complex, real-world concepts.     

On the relationship between recognition speed and accuracy for words rehearsed via rote versus elaborative rehearsal

Tacit within both lay and cognitive conceptualizations of learning is the notion that those conditions of learning that foster "good" retention do so by increasing both the probability and the speed of access to the relevant information. In 3 experiments, time pressure during recognition is shown to decrease accessibility more for words learned via elaborative rehearsal than for words learned via rote rehearsal, despite the fact that elaborative rehearsal is a more efficacious learning strategy as measured by the probability of access. In Experiment 1, participants learned each word using both types of rehearsal, and the results show that access to the products of elaborative rehearsal is more compromised by time pressure than is access to the products of rote rehearsal. The results of Experiment 2, in which each word was learned via either pure rote or pure elaborative rehearsal, exhibit the same pattern. Experiment 3, in which the authors used the response-signal procedure, provides evidence that this difference in accessibility owes not to differences in the rate of access to the 2 types of traces, but rather to the higher asymptotic level of stored information for words learned via elaborative rehearsal.     

Athletes’ Motivation Regulations and Need Satisfaction Across Combinations of Perceived Coaching Behaviors

Cluster analysis was used to identify combinations of perceived coaching behaviors (i.e., autonomy support and four controlling coaching behaviors). Motivation regulations and need satisfaction were tested for differences across profiles. Results revealed 3 profiles of college swimmers (N = 165) based on their responses to measures of study variables. The profiles had relatively more autonomy support or more controlling coaching behaviors or a combination of the 2. The profile with greater autonomy support and lower controlling coaching behaviors reported the most positive motivation experiences. Findings illustrate the independence of these coaching behaviors and offer practical suggestions for college swim coaches.     

Short-term memory,verbal competence,and age as predictors of imagery instructional effectiveness

Children 6 to 11 years of age heard concrete sentences that they were asked to learn. Half the subjects were instructed to construct images representing the sentence meanings. The remaining participants were provided no strategy instructions (control condition). Consistent with previous outcomes, the older children in the imagery condition learned signficantly more than did the older control subjects. There was a slight trend favoring imagery for younger children in the sample. Individual differences in short-term memory and verbal competence were more highly associated with performance in the imagery than in the control condition, such that greater short-term memory and verbal competence predicted better sentence learning in the imagery condition. In particular, short-term memory and verbal competence made unique contributions (relative to age and to each other) to prediction of sentence learning in the imagery condition, but not in the control condition. In short, imagery instruction is more effective with children who are more intellectually competent.     

The effect of children's spontaneous cognitive sets on discrimination learning

Two experiments investigated the role of children's spontaneous cognitive “sets” in pictorial discrimination learning. Lists were constructed to highlight either perceptual or conceptual similarities among the stimuli. In each experiment age by treatment interactions revealed that in comparison to the behavior of older children (sixth graders), that of younger children (kindergartners) is governed more by the perceptible than by the conceptual attributes of stimuli—data in complete accord with Bruner's view of cognitive development.     

Adult-child interaction under dyadic and polyadic conditions

The nature of adult-child interaction was examined under two conditions: dyadic (adult with one child) and polyadic (adult with four children). The subjects were staff and children in day nurseries, who were observed in a specially set-up task situation. In certain respects the interaction assumed different forms depending on group condition. The effects may be seen in stylistic differences in the adults' behaviour: thus in polyads individual children had not only less speech directed to them but also speech that tended to be more directive and prohibitive. While the total number of bids the adults received from children in polyads was considerably greater than in dyads, the increase was a selective one, referring only to requests for help and not to less urgent demands. The main strategy adopted by adults to cope with the increase in demand was by ignoring, the incidence of which was very much greater under polyadic than under dyadic conditions. Joint involvement of adult and child was also much reduced in the former setting. The implications of these findings for children reared under group care conditions are discussed, and attention is drawn to the importance of situational factors in determining caretaker responsiveness.     

EFFECTS OF VERBAL REGULATION AND AGE ON RULE ACQUISITION AND TRANSFER

The ability of 119 children (mean ages 6.2, 8.2, 10.1, and 12.3) to perform rule learning and subsequent transfer tasks was observed utilizing three experimental conditions: overt-verbal, covert-verbal, and control. The performance of the subjects suggests that the child who is forced to verbalize his conceptual strategies will reach criterion faster in the rule acquisition task, and will also be more successful in his attempts to transfer the acquired rule. With regard to the transfer tasks specifically, it was found that overt-verbal learning was significantly more effective than covert-learning, and that the covert-verbal condition yielded significantly higher scores than did the control condition. These results point to the effectiveness of verbal strategies in the acquisition and transfer of learning.

Photograph method fosters direct access to second-language word meaning: Direct evidence from a word-picture matching task

This experiment was designed to investigate conceptual links directly through a word–picture matching task in children. Participants were asked to indicate between two pictures the one depicting the same concept as the newly learned L2 word (target). One of the two pictures was the target, while the other was either semantically related to it or was unrelated. To investigate whether learning methods modulate L2 word processing, two learning methods were compared: an L2-photograph method and an L1-L2 method. Results showed a semantic interference effect only with the L2-photograph method: Children responded more slowly in the related condition than in the unrelated one. The learning method modulated L2 word processing and L2 word meaning was not necessarily accessed through L1 mediation in the first steps of learning. The method used paves the way for the direct investigation of conceptual links.     

The benefit of retrieval practice over elaborative restudy in primary school vocabulary learning

The testing effect is the phenomenon that retrieval practice of learning material after studying enhances long-term retention more than restudying. We examined retrieval practice in primary school vocabulary learning in two experiments. Nine-year-old children studied word definitions and completed exercises according to three learning conditions: pure restudy, elaborative restudy or retrieval practice. Children in the pure restudy condition reread and partly copied the definitions. In the elaborative restudy condition children reread the definitions and connected semantically related words to the target words. Children in the retrieval practice condition recalled the words based on their definitions. Overall, on the fill-in-the-blank test after one week children in the retrieval practice condition outperformed children in the other conditions, but on the multiple-choice test there were no differences. Retrieval practice may be effective for primary school vocabulary learning, but there is uncertainty about the practical value and the magnitude of the retrieval practice effect.     

Effects of modeling rote versus varied responses on response variability and skill acquisition during discrete‐trial instruction

Despite its advantages, discrete‐trial instruction (DTI) has been criticized for producing rote responding. Although there is little research supporting this claim, if true, this may be problematic given the propensity of children with autism to engage in restricted and repetitive behavior. One feature that is common in DTI that may contribute to rote responding is the prompting and reinforcement of one correct response per discriminative stimulus. To evaluate the potential negative effects of rote prompts on varied responding, we compared the effects of modeling rote versus varied target responses during the teaching of intraverbal categorization. We also evaluated the effects of these procedures on the efficiency of acquisition of any one correct response. For all four children, any increase in varied responding was fleeting, and for two participants, acquisition was slower in the variable‐modeling condition.
