On average, men outperform women on mental rotation tasks. Even boys as young as 4 1/2 perform better than girls on simplified spatial transformation tasks. The goal of our study was to explore ways of improving 5-year-olds' performance on a spatial transformation task and to examine the strategies children use to solve this task. We found that boys performed better than girls before training and that both boys and girls improved with training, whether they were given explicit instruction or just practice. Regardless of training condition, the more children gestured about moving the pieces when asked to explain how they solved the spatial transformation task, the better they performed on the task, with boys gesturing about movement significantly more (and performing better) than girls. Gesture thus provides useful information about children's spatial strategies, raising the possibility that gesture training may be particularly effective in improving children's mental rotation skills.  相似文献

This study investigated the costs associated with the Type B behavior pattern in an achievement task completed by 84 male and female fifth- and sixth-grade students preselected for their Type A-B scores. We hypothesized that the achievement behaviors of Type B girls, in comparison to boys and Type A girls, would be most negatively affected by failure experiences. Hypothesis-testing strategies were assessed during a discrimination task that included eight training, four forced failure, and four success problems. Self-ratings of performance were obtained following failure and success experiences, and preference for challenge was measured. As expected. Type B girls in comparison to all other children showed the greatest decrement in their hypothesis-testing strategies during failure, appeared to have the most difficulty recovering from failure, were the only group to view their performance following success as poorer than other children's performance, and exhibited the least preference for challenge. These findings suggest that Type B girls are at risk in achievement situations.  相似文献

This paper concerns underarm throwing by girls 7 to 12 years of age. Each movement component by trained and untrained girls in underarm throwing or windmill softball pitching was examined. Movement characteristics of ball release, arm motion, trunk activity, and stepping were analyzed to capture experience- and age-related differences in underarm throwing. A total of 48 young girls participated: 25 untrained (age 9.7 yr.), 14 trained/league (age 10.9 yr.), and 9 trained/formal (10.4 yr.). Performance was videotaped individually and evaluated by three observers. Analyses suggest that, while age did not affect performance, the type of training experience influenced the girls' performance on each of the four movement components. The wrist and trunk were identified as showing the most significant progression with experience. The findings have important implications about changes during acquisition of underarm throwing skills.  相似文献

Different individuals approach mathematical problems in a variety of ways, with these different approaches also reflected in over-all cognitive styles. This investigation had two purposes, first, to determine whether good and poor arithmetic problem solvers differ substantially in cognitive style, and second, to determine whether the students, after training in techniques of solving arithmetic problems, improve their performance with no significant change in cognitive style. A total of 98 third graders participated (mean age 8.1 yr.; 50 boys, 48 girls). The Matching Familiar Figure Test was used to classify the students by cognitive style as either Reflective or Impulsive. Students also were given training with different problem-solving exercises for different arithmetic problems. The training program in problem-solving strategies did not improve performance on arithmetic problems for Reflective students; however, Impulsive students' performance did improve after training.  相似文献

An overt rehearsal procedure was used to investigate the relationship between children's rehearsal strategies and free recall performance. Previous work has shown that developmental differences in rehearsal content, rather than rehearsal frequency, affect recall performance. This experiment investigated the effects of increased processing time and rehearsal training upon recall. Third-grade girls (age 8) were able to use additional processing time to increase the activity of their rehearsal, and they showed corresponding improvement in recall. In contrast, third-grade boys (age 8) and sixth-grade boys and girls (age 12) did not take advantage of a slower presentation rate to rehearse more actively, and their recall did not change. Further, even without additional processing time, both the third-grade boys and girls were able to use an instructed active rehearsal strategy to facilitate their recall. The direct manipulation of rehearsal activity and the resulting improvement in recall provide experimental support for the proposed relationship between rehearsal content and recall from long-term memory store.  相似文献

The effect of imagery based strategy training on retention in children of 9?C10?years age (n?=?60) was investigated. The imagery instructed group evinced greater recall than the control group on measures of accuracy and speed of recall. Also the recall performance of girls was better during training and maintenance sessions. The speed of recall was significantly faster in the imagery instructed group as compared to control group. As found in the follow up the strategy instructed group continued to use the strategy in the absence of explicit instructions to do so. The findings demonstrate the feasibility of the use of effective mnemonic strategies.  相似文献

The authors examined effects of feedback and explanation on false belief performance. Thirty-three children (42–54 months; 15 girls, 18 boys) were randomly assigned to four treatment conditions: explanation, feedback, feedback researcher explains, and feedback child explains. Children completed false belief tasks during pretraining, 8 training sessions, and posttraining across 6 weeks. Language comprehension was assessed at pretraining. The authors hypothesized that children would improve most when training involved feedback and explanation. Generalized estimating equations modeling was used to analyze the data. Children who received feedback and generated explanations for characters’ false beliefs improved across training sessions more so than children in other conditions. Children's explanations for false beliefs also were explored. Implications of the findings are discussed.  相似文献

Self-recording procedures were used by four adolescent girls to increase work and comments (cues) that evoked staff praise during vocational training sessions in a maximum-security institution for offenders. The girls were selected on the basis of their not responding to a staff-directed token program. The self-recording procedures were directed by a therapist who saw the girls outside the vocational training sessions. According to a multiple-baseline design, self-recording of work was introduced sequentially to each of the two or three settings the girls attended each day. A few days after work had increased, self-recording of cues was introduced. Tokens were delivered by the therapist for work and cues recorded by the girls. Work and cues increased following self-recording for three of the girls and increased cues evoked higher rates of staff praise. Girl and staff behaviors were maintained during short follow-up periods when tokens were not given for the girls' records. The procedures failed to effect desirable changes with a fourth girl's work, and self-recording of work was terminated without introducing cueing.  相似文献

This study examines the mediational role of gender in the effects of two patterns of cognitive and self-regulatory strategy interventions in the writing self-efficacy calibration of students with learning disabilities (LD). 121 5th and 6th Primary grade students with LD (43 girls and 78 boys), ranging in age from 10 to 12 years old were randomly allocated either to one of the experimental intervention groups, (n=48, 19 girls and 29 boys), and followed a intervention program based on the Self-Regulated Strategy Development Model, or they received training based on the Social Cognitive Model of Sequential Skill Acquisition (n=31, 15 girls and 26 boys), or alternatively they were allocated to the ordinary instruction group (n=32, 9 girls and 23 boys). Writing performance was assessed using two types of writing evaluation: a reader-based score concerned with structure, coherence and quality, and a text based score regarding productivity, coherence and structure. Writing self-efficacy beliefs were also assessed using a self-report scale including eight items about the students' confidence in completing a writing task and to gain specific writing skills. The results suggest that the miscalibration of writing self-efficacy in girls with LD was significantly modified to a more realistic calibration of their writing competence after experimental intervention. However, the findings do not confirm the same clear statement for boys.  相似文献

The problem-solving performance of young boys and girls was examined in three conditions in which good performance was indicated as being appropriate for boys, for girls, or for both boys and girls. The relations between task scores and five sex-role measures were also examined. As predicted, the boys performed significantly more poorly when the task was indicated as one that girls did better. The girls' performance was not affected by the conditions of the study. The girls' problem-solving scores did not differ significantly from the boys' scores. There was some relationship between the task scores and the sex-role measures for boys, but not for girls. Associations among the sex-role measures were not high.This research was supported by a DGES-FCAC research grant from the government of Quebec, Canada.  相似文献

We applied SMR/theta neurofeedback (NF) training at central sites of 20 Israeli children aged 10-12 years, half boys and half girls. Half of the subjects received C3 training and the other half C4 training, consisting of 20 half-hour sessions. We assessed the effects of training on lateralized lexical decision in Hebrew. The lateralized lexical decision test reveals an independent contribution of each hemisphere to word recognition (Barnea, Mooshagian, & Zaidel, 2003). Training increased accuracy and sensitivity. It increased left hemisphere (LH) specialization under some conditions but it did not affect interhemispheric transfer. Training did affect psycholinguistic processing in the two hemispheres, differentially at C3 and C4. Training also increased hemispheric independence. There were surprising sex differences in the effects of training. In boys, C4 training improved LH accuracy, whereas in girls C3 training improved LH accuracy. The results suggest that the lateralized NF protocol activates asymmetric hemispheric control circuits which modify distant hemispheric networks and are organized differently in boys and girls.  相似文献

The purpose of this study was to investigate the effects of the Technique and Games approaches on girls' soccer performance and motivation. The Technique approach focuses on technique instruction using drills, whereas the Games approach places emphasis on tactic instruction with modified games. 37 girls, 12 to 13 years old, were taught 15 soccer lessons by the Technique approach and 35 girls by the Games approach. At the beginning and at the end of the research soccer matches were videotaped and evaluated by Oslin, Mitchell, and Griffin's Game Performance Assessment Instrument. Girls' motivation was assessed on the Intrinsic Motivation Inventory. The Games group had significantly better scores after training on tactical behaviour and intrinsic motivation than the Technique group. There were no significant differences in skill execution between groups trained under the two approaches. Considering the importance of intrinsic motivation for a lifelong, physically active lifestyle, researchers could focus study on the approaches and girls' motivation.  相似文献

The effects of EMG biofeedback training on cursive handwriting were investigated for 4 girls and 5 boys in Grade 4. A significant reduction in EMG between the first baseline session and the last training session was obtained. Four of 5 characteristics of handwriting improved significantly. The need for carefully designed research comparing EMG biofeedback training and relaxation training was indicated. A self-control factor in handwriting was hypothesized.  相似文献

Assertiveness training and its relationship to smoking behavior and how young adolescent boys and girls differ with respect to assertion was investigated. A total of 161 seventh-grade students from six health education classes participated. Two classes received an innovative smoking education program, two classes received assertiveness training plus an innovative smoking education program, and two classes received only the smoking education program usually offered by the school. Locus of control and levels of assertion and smoking behavior were assessed at pre- and posttest. The results indicate that boys are significantly more assertive than girls at age 12 (p = .0018), and this assertiveness increases equally over the next four years (p less than .0001). There were no significant differences in smoking behavior among the three groups; however, trends in smoking behavior in the desired direction were observed. There is no significant difference in smoking behavior between boys and girls. In this respect the sexes have reached equality, that is, girls are initiating cigarette smoking as frequently as are boys. Finally, there were no significant changes in assertion among the groups. It is concluded that the utility of assertiveness training for young adolescents is questionable.  相似文献

Three reliably measured components of conversation-questioning, providing positive feedback, and proportion of time spent talking-were identified and validated as to their social importance. The social validity of the three conversational behaviors was established with five female university students and five female junior-high students. Each was videotaped in conversations with previously unknown adults. The conversational ability of each girl was evaluated by a group of 13 adult judges who viewed each tape and rated each conversant "poor" to "excellent" on a seven-point rating scale. The average ratings of the girls correlated at r = 0.85 with the specified behavioral measures. These procedures were replicated with additional subjects and judges and yielded a correlation of r = 0.84. The high correlations between ratings and the objective measures suggested that the specified conversational behaviors were socially important aspects of conversational ability. Employing a multiple-baseline design across the behaviors of asking questions and providing positive feedback, an attempt was made to train four girls who used these behaviors minimally to engage in the behaviors in conversations with adults. Adult judges were again employed to rate randomly selected samples of the girls' skills in pre- and posttraining conversations. The average ratings of the girls before training were lower than both the university girls and the junior high-school girls. After training, the girls' conversational abilities were rated substantially higher than those of their junior high-school peers. These rating data validated the benefits of the training and the social importance of the behavioral components of questions and feedback in conversation. The authors suggest that it may be necessary for traditional behavior analysis measurement systems to be supplemented by social-validation procedures in order to establish the relationship between "objectively" measured behaviors and complex classes of behavior of interest to society.  相似文献

The purpose of this analysis of data from a larger investigation was to assess effects of anthropometric factors on free throw shooting performance of 15 girls from Michigan and 18 from Puerto Rico. Subjects performed 60 free throws (10 trials x 3 ball sizes x 2 basket heights). Correlations were low, with two exceptions, .53 between shooting performance at the low basket and grip strength (as measured by hand grip dynamometer) for girls from Michigan, and .49 for hand width and performance at the low basket for girls from Michigan.  相似文献

This study investigated strategy and performance differences between right-handed boys and girls on a mental rotation task. Based on predictions from Casey and Brabeck's (1990) theory of sex differences, the study was also designed to identify a target group of right-handed girls with the optimal combination of genetic and environmental factors (high math/science achievers with nonright-handed immediate relatives). They were predicted to show strategies and performance more similar to those of the boys than to those of both the low math/science achieving girls and the high math/science girls with all right-handed immediate relatives (predicted to have the nonoptimal genotype). Strategy preference was measured using selective interference, whereby subjects solved mental rotation items concurrently with either verbal or visual-spatial interference tasks. Group comparisons were made on the amount of decrement in mental rotation performance as a result of the two types of interference tasks. This provided a basis for comparing the groups on the use of visual-spatial or verbal strategies on the mental rotation task. The boys: (1) did not show a significant advantage over the girls on the mental rotation items, but (2) did depend more on visual-spatial strategies than the girls, and (3) depended less on verbal strategies than the girls. The target girls: (1) outperformed the low math/science achieving girls on the mental rotation items and did not show a significant advantage over the other high math/science group, (2) depended more on visual-spatial strategies than both the other two groups of girls, and (3) depended less on verbal strategies than the low math/science girls, while showing no significant difference compared to the nonoptimal high math/science girls. Examining within-group differences, the boys preferred visual-spatial strategies, while the girls in both the nontarget groups preferred verbal ones. However, for the target girls, no within-subject strategy differences were found. The present findings support the theory that, like the boys, the target girls depend more on visual-spatial strategies than do other girls. It is possible that the target girls use a combination of visual-spatial and verbal strategies when solving mental rotation tasks.  相似文献

Because shy children are at risk for poor academic achievement, it is important to examine factors that contribute to variability in the relation between individual differences in shyness and cognitive functioning before school entry. The authors examined whether on-task facilitative private speech—a proxy of self-regulation—moderated the association between individual differences in shyness and performance on an executive function (EF) task in 52 typically developing 4-year-olds. They found that private speech interacted with shyness to predict performance on the EF task in girls but not in boys. More specifically, shyness was inversely related to EF task performance when girls used low amounts of regulatory private speech, but was positively related to performance when girls used high amounts of regulatory private speech. These preliminary findings are discussed in the context of implications for shy children in educational settings.  相似文献
