An 11-parameter Markov model of stages of learning, which was developed by Brainerd et al., will be presented. The focus will be on parameter interpretation in terms of long-term memory (LTM) processes. Next the model will be used to examine the contribution of these various LTM processes to Schooltype and Age differences in a word-pair memorization experiment. Subjects were 8 and 11-year-old normal-achieving (NA) children from regular elementary schools and 8 and 11-year-old children from special schools for learning disabled (LD) children. One of the main conclusions is that the Schooltype × Age interaction which was demonstrated for traditional performance measures, can be explained by LD children's little developmental progress in storage processes and deviations from normal development in aspects of the acquisition of retrieval algorithms. No deficiences were, however, detected in the LD children's rerention ability early in the task, and in the so-called heuristic retrieval operations.  相似文献

The relationships of Israeli mothers and fathers with their 38 preterm infants during hospitalization were traced in a short-term longitudinal study. Parent-infant interactions were observed and self-reports of parental feelings and perceptions were assessed twice: at the beginning and end of the nursery period. Mothers engaged in more caregiving, talking, and holding during initial contacts, but the disparity in maternal and paternal interactions decreased with time. Except for caregiving, in which mothers still surpassed fathers, fathers equaled mothers in all other activities at the time of the infants' discharge from the hospital. Fathers consistently surpassed mothers in playing and stimulating. Mothers perceived their infants to be more difficult than did fathers but reported enjoying them more. With time, parents were less disappointed and concerned over the infants' well-being but perceived them as more difficult. The data also demonstrated an association between infant behavioral states, parental feelings and perceptions, and parental behavior.  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
