Deaf subjects who represented a wide range of reading abilities were tested on a number of factors including reliance on phonological recoding as well as several metacognitive abilities. The sample consisted of 19 high school students who were prelingually and profoundly deaf. Subjects were given a set of paper and pencil tests that included an assessment of phonological recoding ability as well as the measures designed by Baker (1984) to assess metacognitive skills in reading. Results indicated that deaf subjects demonstrated a significant degree of reliance on phonological recoding, but that individual differences in reliance on phonological recoding showed no relationship to reading skill (r = .02). Individual differences on the metacognition measures, however, showed a strong relationship to reading ability (r = .65, p less than .01). The implications for remedial instruction for deaf students are discussed. 相似文献

Although research has established the long-term damaging effects of incest, these efforts have suffered from the lack of valid, standardized assessment instruments. The present study reports on the construction and factor validation of the Response to Childhood Incest Questionnaire (RCIQ), a self-report instrument that assesses a range of commonly reported symptoms experienced by adult survivors of incest. A clinical population of 104 adult women who had experienced childhood or adolescent incest completed the RCIQ. A factor analysis of the RCIQ items revealed seven factors which corresponded to hypothesized stress response themes experienced by survivors of traumatic events. These factors include vulnerability and isolation, fear and anxiety, anger and betrayal, reaction to the abuser, sadness and loss, and powerlessness. In addition, four factors corresponded to the diagnostic criteria for post-traumatic stress disorder: intrusive thoughts, avoidance and intrusive emotions, detachment, and emotional control and numbness. The usefulness of the RCIQ as a pre- and post-treatment measure and the need for further research is discussed. 相似文献

One hundred and eighty-one teacher training students sat three attitude measuring instruments to investigate the relationships between attitudes to self, attitudes to others and attitudes to educational practices. Clinical studies within the ambit of Rogerian psychotherapy suggest that a relationship between self and other attitudes should be positive. Substantial and statistically significant positive correlations, in the order of p<0.01, emerged consistently in this study between attitudes to self and attitudes to a range of others and to progressive child centred educational practices. Self acceptance level would seem to be an index of attitudes to a wide range of others. This relationship provides a principle of utmost importance for human relationships since the application of psychological processes to enhance the self concept should facilitate as a corollary a decrease in interpersonal tensions and inter group conflict. This relationship is of particular consequence in the teaching context since teaching is a sharing of self with others. The results of the study suggest that those with low self acceptance prefer (p<0.01) to avoid close encounters with pupils and prefer a more traditional formal teaching style. 相似文献

Little responding develops to a conditioned stimulus (CS) that is placed in a random relation to an unconditioned stimulus (US). However, if the USs not preceded by that CS are themselves signaled by another stimulus, then the CS does come to elicit responding. This result has been attributed (e.g., by Durlach, 1983) to the signal’s blocking of conditioning to background cues that otherwise would prevent conditioning of the CS. However, Goddard and Jenkins (1987) have suggested the alternative that signaling the USs promotes responding due to the adventitious creation of periods of signaled nonreinforcement. Two experiments were conducted to assess this alternative, involving an autoshaping preparation in pigeons. In Experiment 1, little responding to a keylight CS presented in a random relation to a food US occurred, despite the explicit presentation of a discrete noise signaling periods of no food in the intertrial interval (ITI). Experiment 2 was designed to replicate the procedure of Goddard and Jenkins, in which an auditory stimulus extended throughout the ITI of a random schedule, terminating only prior to extra USs and during the CS. Contrary to their findings, little responding developed to the target CS. However, responding did develop when the sound-free period occurred only prior to the extra USs. These results offer little support for the hypothesis that signaled periods of nonreinforcement promote responding on random schedules. However, they are consistent with the view that signaling of ITI USs acts by preventing conditioning of potentially competitive background cues. 相似文献

Research has shown a positive relationship between academic engaged time (AET), academic learning time (ALT) and student achievement. Previous work has reported a relatively non‐intrusive, cost‐effective method for increasing AET in the classroom involving the presentation of research information followed by feedback to teachers of students’ AET in their classes. This study aimed to replicate these findings in a primary school setting and to establish what effects the information plus feedback had on teachers’ instructional behaviours which have been found to correlate with students’ AET and ALT. In addition, we looked at the effects of more precise feedback based on students’ task difficulty measures. The results provided strong support for the utility and efficacy of information plus feedback as a method for increasing student AET and ALT and for enabling teachers to change their instructional behaviours in the direction of published research findings. 相似文献

To investigate the relationship between achievement and IQ in the learning-disabled (LD) population, changes in the IQ scores of LD students from the early elementary grades to the high school grades were studied. The intercorrelations among those IQ scores and a variety of achievement scores were then explored for the purpose of ascertaining causal relationships. The results were interpreted as support for the contention that the underachievement of LD students (in particular, reading underachievement) plays a predominant causal role in the achievement-IQ relationship in this population. 相似文献

The effects of three routine classroom tasks upon heart rate reactivity were investigated with a sample of 30 typical fifth-grade children. Instructions for a mental arithmetic task, the mental arithmetic task itself, and silent reading were administered under standardized conditions, with a reward being offered for performance on the mental arithmetic task to enhance competition. Heart rate was individually monitored each second during these tasks, and data were collected on mental arithmetic performance and reading ability. Results indicated that some children showed large increases in their heart rates during the three tasks, and that these children should be considered as at-risk in terms of their cardiac health. 相似文献

Self-regulating academic learning and achievement: The emergence of a social cognitive perspective 总被引:8,自引:0,他引:8
Barry J. Zimmerman 《Educational Psychology Review》1990,2(2):173-201
For three decades, social cognitive researchers have studied children's development of self-regulation as an achievement of socialization processes. I recount historically the emergence of a social cognitive perspective on self-regulation and identify its unique features. Two essential characteristics of students' self-regulated academic learning have been identified — their use of strategies and perceptions of self-efficacy. A social cognitive model of academic self-regulated learning is proposed that integrates triadic determinants of self-regulated learning (personal, behavioral, and environmental) on the basis of a strategic control loop. When students monitor their responding and attribute outcomes to their strategies, their learning becomes self-regulated, and they display increased self-efficacy, greater intrinsic motivation, and higher academic achievement. 相似文献
