Only a limited number of species have been found capable of generalized matching-to-sample (MTS) after exposure to relatively few training exemplars. We trained a juvenile, experimentally naive California sea lion (Zalophus californianus) in MTS, using a pair of three-dimensional objects as samples. Successful matching to a criterion of 90% correct or better over 2 successive sessions was attained in 12 sessions (269 trials and 70 errors). Two subsequent “partial” transfer tests, in which each of the two training objects was paired with a novel test object, and four additional transfer tests, all with novel objects, were presented following training. An 80% performance criterion over 2 successive sessions was reached, or closely approximated, in from 2 to 4 transfer sessions for all transfer tests; errors to criterion tended to be reduced across the successive novel transfer tests and were as few as five during the final two tests; and performance on the first 48 trials of the last two novel transfers was not significantly different from a near-ceiling level baseline performance measure. Neophobic responses of the sea lion to new objects precluded an unbiased evaluation of immediate (Trial 1) transfer. The sea lion’s short-term memory for sample objects was also measured. Matching performance was maintained at a level of 78% correct responses or better for delays through to 45 sec after removal of the sample object. At a 58-sec delay, the longest tested, performance declined to 69% correct responses. These retention levels are only somewhat below levels reported for dolphins and nonhuman primates tested on visual delayed MTS, but they are above levels typically reported for pigeon subjects.  相似文献

This study examined the effects of (a) interactive reading homework, and (b) parent involvement with children during homework on students' responses to inference questions. Interactive reading homework refers to homework designed to involve both parents and children and to facilitate student reasoning. The participants were 84 parents and 84 second grade students from three Alabama elementary schools. Data were gathered using pre- and post student inference tests, parent behavior checklists, and parent homework questionnaires. The results indicated that interactive reading homework increased both parental involvement during the completion of reading homework assignments and students' ability to draw inferences.  相似文献

Abstract

Zero, 4, and 8 second delays in knowledge of results were used in a computer-assisted instruction task learned by sixty men and sixty women. The task was a tutorial constructed-response program dealing with binary numbers, presented via an electric typewriter. Criteria used were (a) time taken to complete the program (corrected for delay times), (b) number of correct responses during learning, (c) number of correct responses made on an achievement test on the program, and (d) scores on a test of expressed attitude toward computer-assisted instruction (CAI). Women completed the task more quickly, and showed poorer attitudes toward CAI when the delay interval was 8 seconds. Other performance criteria were unaffected.  相似文献

ObjectiveParent-child interaction therapy (PCIT) has been found to reduce future child abuse reports among physically abusive parents. Reductions in observed negative parenting behaviors mediated this benefit. The current study examined session-by-session interaction sequences in order to identify when during treatment these changes occur and how much the trajectory varies from case-to-case.MethodSession-by-session parent-child interaction sequences, using the Dyadic Parent-Child Interaction Coding System-II (DPICS-II) categories, were coded for 22 child welfare involved parent-child dyads undergoing PCIT for child physical abuse. A total 5,436 interactions across PCIT were coded and analyzed using growth curve analysis.ResultsAt pre-treatment baseline, negative and positive parental responses were about equally likely to follow a child positive behavior. This pattern changed rapidly during PCIT, with rapid increases in positive parental responses and decreases in negative parental responses to appropriate child behavior. A quadratic growth pattern accounted for 70% of observed variance and virtually all change occurred during the first three sessions.ConclusionChanges in observed abusive parent-abused child interaction patterns can occur early in PCIT, a parenting intervention that involves direct coaching and practice of skills. These benefits sustained throughout treatment.Practice implicationPrior to receiving behavioral parent training (PCIT), parents who have physically abused their children failed to match their parental response to their children's behavior. This pattern of interaction improved rapidly and substantially during the first three sessions of PCIT. The changes in the patterns of interaction also remained relatively stable for the remainder of treatment while parents continued to practice positive parental responses as well as began practicing effective discipline techniques. This suggests that use of immediate parent feedback through coaching, explicit directions to parents in how to respond to child behavior, and customization of the application of skills to the problems that arise in session are important components to effective parenting programs with physically abusive parents. Targeting these behaviors with PCIT has been found to reduce rates of recidivism, further supporting clinical application of PCIT in these cases.  相似文献

ObjectiveThe present study extends field research on interviews with young children suspected of having been abused by examining multiple assessment interviews designed to be inquisitory and exploratory, rather than formal evidential or forensic interviews.MethodsSixty-six interviews with 24 children between the ages of 3 and 6 years who were undergoing an assessment for suspected child abuse were examined. Each child was interviewed 2, 3, or 4 times. The interviewer's questions were categorized in terms of openness (open, closed or choice), in terms of the degree of interviewer input (free recall, direct, leading, suggestive), and for topic (whether the question was abuse-specific or nonabuse-related). Children's on-task responses were coded for amount of information (number of clauses) reported in relation to each question type and topic, and off-task responses were categorized as either ignoring the question or a diverted response.ResultsChildren provided a response to most questions, independent of question type or topic and typically responded with one or two simple clauses. Some children disclosed abuse in response to open-ended questions; generally, however, failure to respond to a question was more likely for abuse-specific than for nonabuse-related questions.ConclusionThe findings are discussed in terms of the growing literature on interviewing children about suspected abuse, particularly in interviews conducted over multiple sessions.Practice implicationsAssessment of suspected child abuse may involve more than a single investigative interview. Research examining children's responses to questioning over multiple interviews (or single interviews conducted over multiple sessions) is necessary for the development of best practise guidelines for the assessment of abuse.  相似文献

ABSTRACT

This randomized control trial study evaluated the effectiveness of the solution-focused approach in addressing academic, motivational, and socioemotional needs of 14 children with reading difficulties. The intervention group received five 40-min solution-focused sessions. The control group received academic homework support. Results showed advantages for the intervention condition in 26 out of 38 measures. The mean eta-squared effect size for intervention was .20 (very) large. For the control group, there were only 10 effects favoring it and the mean was .09, a medium sized effect, both significantly greater than 0 (p < .01). Comparisons of the solution-focused brief therapy (SFBT) effect sizes to the mean of the control showed it was significantly larger (p < .001), confirming that SFBT was an efficacious intervention in this sample.  相似文献

Present study investigated impact of pre-service teachers’ implementation of a constant time delay procedure within the framework of transition-based teaching on teaching pre-academic skills to three preschool children with developmental delays during transitions in inclusive classrooms. A multiple probe design across behaviors replicated across three children was used. Results indicated pre-service teachers could implement transition-based teaching with very high fidelity following a brief training session; pre-service teachers’ implementation of transition-based teaching resulted in acquisition of pre-academic skills by all three participating children with developmental delays; children generalized the pre-academic skills they learned to other teachers, settings, and materials; and they maintained high levels of correct responding during the follow-up sessions. Moreover, pre-service and preschool teachers found transition-based teaching acceptable and effective. Directions for future research and practice are discussed.  相似文献

The present study examined the longitudinal associations between children’s perceptions of parental involvement in math homework (control and support) and their math performance and motivation (task-persistent homework behavior and math self-concept). Children (n = 512) reported their perceptions concerning parental involvement in sixth-grade math homework. In grades 3 and 6, children completed math tests, evaluated own math self-concept, and their mothers (n = 420) evaluated task persistence during homework. The results showed that low self-concept in math predicted increased parental control, which in turn related to low math performance, task persistence, and math self-concept. Second, perceived parental support was related to increased task persistence during homework. Finally, parental control was especially detrimental for boys’ task persistence and math self-concept.  相似文献

Pigeons (nine groups of seven) were given one acquisition session of 20 trials. The following day their responding was extinguished, and after a 30-min rest period they were tested for residual response strength. The groups differed with respect to (1) whether a distinctive stimulus was presented during acquisition on the first trial, the 15th trial, or not at all, (2) whether or not responses to the distinctive stimulus were reinforced, and (3) whether a distinctive stimulus, a standard stimulus, or a completely novel stimulus was presented on the test trial. Results supported the position that a stimulus associated with the onset of an acquisition session, but not with the extinction session, evokes greater response strength on a spontaneous recovery test trial than do other stimuli in the acquisition session. This holds true even if responses to this stimulus are never reinforced. In addition, it was found that, unlike a previous study that invoked five daily acquisition sessions, pigeons did not demonstrate increased responding to a novel stimulus.  相似文献

Students enrolled in the Optometry program at the University of Manchester are required to take a functional anatomy course during the first year of their studies. Low mean scores in the written examination of this unit for the past two academic years energized staff to rethink the teaching format. Interactive sessions lasting 20 minutes each were introduced during the two hour lecture sessions. In these sessions students reinforced their anatomical knowledge learned in lectures, through playing games such as anatomy bingo and solving anatomical anagrams. In addition, five e‐learning modules were also introduced for students to complete in their own time. A pre‐ and postcourse questionnaire were distributed to obtain student views on their expectations of the course and interactive sessions. Comparisons were made between written examination results from 2008 to 2009 to written examination results from the previous five academic years to see if the interactive sessions and e‐learning modules had any impact on student knowledge. In addition, comparisons were made between student performances on the functional anatomy course with their performance in all of the other assessments taken by the students during their first year of study. Analysis of the questionnaires showed that student's expectations of the course were fulfilled and the interactive sessions were well received by the majority. There was a significant increase (P ≤ 0.01) in the mean examination score in 2008–2009 after introduction of the interactive sessions and e‐learning modules compared with scores in previous years. The introduction of interactive sessions has increased student enjoyment of the module and along with the e‐learning modules have had a positive impact on student examination results.

Homework: a cross-cultural examination   总被引：5，自引：1，他引：5  
Cultural differences in the amount of time spent on homework and in beliefs and attitudes about homework were investigated through interviews with more than 3,500 elementary school children, their mothers, and their teachers. The children lived in 5 cities: Beijing, Chicago, Minneapolis, Sendai (Japan), and Taipei. Chinese children were assigned more homework and spent more time on homework than Japanese children, who in turn were assigned more and spent more time on homework than American children. Chinese children also received more help from family members with their homework than American and Japanese children. Chinese children were found to have more positive attitudes about homework than American children; Japanese children's attitudes were between those of the Chinese and American children. Relations between amount of time spent on homework by children, amount of time parents spent assisting their children with homework, and children's achievement were also explored. The views of both parents and teachers about the value of homework are discussed.  相似文献

Abstract

Three groups of fifteen children about 8 years of age were selected such that one group displayed a distinct preference for auditory over visual stimuli, one group displayed a distinct preference for visual over auditory stimuli, and one group displayed no preference. The Ss then learned lists of CVC trigrams presented through preferred and nonpreferred modalities. Results indicated that recall was best when the stimuli during learning were presented through the preferred sensory modality and worst when presented through the nonpreferred modality. Children without a sensory preference scored between the other two extremes, learning equally well under either modality. It was concluded that modality preference can be an important variable in learning and that providing congruity between a learner’s preference and mode of instruction should be investigated.  相似文献

Abstract

This paper synthesizes empirical studies of homework and of various homework strategies on the academic achievement and attitude of elementary and secondary students. A computer search yielded 15 published and unpublished studies with explicit statistical results. Fifty-four characteristics of treatments, contexts, conditions, validity, and outcomes were coded for each study. About 85% of the effect sizes favored the homework groups. The mean effect size is .36 (probability less than .0001). Homework that was graded or contained teachers' comments produced stronger effects (.80).  相似文献

While research demonstrates the importance of numeracy-related activities performed at home for young children's mathematics achievement, few studies involve observational studies of the processes which support children's mathematical learning at home. On this premise, this study reports evidence from numeracy-related interactions between parents and their four-year-old child during cookery sessions at home. Numeracy group parents who received instructions to incorporate additional mathematics into the activity provided significantly more numeracy guidance and also created more opportunities for their children to practice advanced mathematics. Comparison group parents provided enough numeracy guidance to complete the recipe but rarely provided extensive or advanced numeracy guidance. Children in the numeracy group generated significantly more correct math responses during the activity than comparison group children, though there were no significant differences on the post-test. The findings suggest the need to raise parental awareness of opportunities to support and encourage mathematics in activities at home.  相似文献

Abstract

Cooperative and collaborative learning are recognized as valuable components of classroom learning. However, many questions remain regarding how teachers might structure and guide children's group-learning experiences. An ethnographic case study of 29 Grade 6 and Grade 7 students who worked in groups over 5 weeks was examined to determine what was learned. Data included audiotape recordings of 6 groups of children working together across 11 work sessions, student interviews, children's self-evaluations and drawings, and research reports. Findings revealed that when working in groups, children require periods of unstructured time to organize themselves and to learn how to work together toward a mutual goal.  相似文献

ABSTRACT

This study investigated in a longitudinal design how 74 Dutch children with dyslexia and 39 typically developing peers differed in sequential versus spatial implicit learning and overnight consolidation, and it examined whether implicit learning related to (pseudo)word reading development in Grades 5 and 6. The results showed that sequential, but not spatial, learning predicted growth in reading skills in children with and without dyslexia. Sequential implicit learning was also related to growth in pseudoword reading skills during an intervention in children with dyslexia, retrospectively. Furthermore, children with dyslexia had longer reaction times in general but did not differ from typical readers in how well or how quickly they learned either on an implicit learning task or in their overnight consolidation.  相似文献

The present study examined indirect effects of modifying appropriate classroom behaviour by itself and academic performance by itself. Of particular interest were changes in appropriate behaviour as students were reinforced for correct work. Five disruptive boys were given arithmetic assignments during daily 20-minute experimental sessions. Changes in appropriate behaviour and arithmetic performance were measured during the following phases: (a) an initial baseline phase; (b) reinforcement for appropriate behaviour alone; (c) return to baseline; (d) reinforcement for correct arithmetic work. It was found that reinforcing appropriate behaviour increased that behaviour, but produced little improvement in arithmetic performance. However, reinforcing arithmetic performance not only increased correct work, but resulted in a high rate of appropriate behaviour as well. The implications of these findings for the management of classroom behaviours were discussed.  相似文献

ABSTRACT

The author examined how characteristics related to individual, family, and school environments contribute to immigrant students’ homework completion. Participants were 192 newcomers in an urban high school designed to serve English language learners. Hierarchical multiple regression analyses were conducted with data compiled from a larger project on role of homework in immigrant adolescents’ academic lives. The author found that students’ homework completion is shaped by (a) gender, engagement in school, homework environment and learning styles; (b) parental homework support and family conflict; and (c) perceived school violence and school homework supports. The effect of perceived school violence on homework completion differed for boys and girls. Boys’ homework completion was more adversely affected by higher perceptions of violence at school than that of girls.  相似文献
