There is evidence that spatial thinking is malleable, and that spatial and mathematical skills are associated (Mix et al. [2016] Journal of Experimental Psychology: General, 145, 1206; Mix et al. [2017] Journal of Cognition and Development, 18, 465; Uttal et al. [2013] Psychological Bulletin, 139, 352). However, few studies have investigated transfer of spatial training gains to mathematics outcomes in children, and no known studies have compared different modes of spatial instruction (explicit vs. implicit instruction). Based on a sample of 250 participants, this study compared the effectiveness of explicit and implicit spatial instruction in eliciting near transfer (to the specific spatial skills trained), intermediate transfer (to untrained spatial skills) and far transfer (to mathematics domains) at age 8. Spatial scaling and mental rotation skills were chosen as training targets as previous studies have found, and proposed explanations for, associations between these skills and mathematics in children of this age (Journal of Experimental Psychology: General, 145, 2016 and 1206). In this study, spatial training led to near, intermediate and far transfer of gains. Mental visualization and proportional reasoning were proposed to explain far transfer from mental rotation and spatial scaling skills respectively. For most outcomes, except for geometry, there was no difference in the effectiveness of implicit (practice with feedback) compared to explicit instruction (instructional videos). From a theoretical perspective, the study identified a specific causal effect of spatial skills on mathematics skills in children. Practically, the results also highlight the potential of instructional videos as a method of introducing spatial thinking into the classroom.  相似文献

A communication skills training of insurance company employees was devised and evaluated. Study 1 compared trained and untrained employees on their Reflective listening (RL; Rogers, 1951) skills before and after a 16-hr training, as they conversed with a confederate who rated them, and their responses were categorized. In a follow-up Study 2, some of the employees audiotaped conversations with customers, and their responses were categorized as well. In a validation Study 3, students rated conversations by employees who used more or less RL. Results showed that training increased RL, and that the skills were subsequently transferred to an authentic setting. Results did not show that trained employees were evaluated differently than untrained. Implications of the results are discussed.  相似文献

Four handicapped children were taught four positive social-emotional behaviors: smiling, sharing, positive physical contacting, and verbal complimenting, using instructions, modelling, and praise. Rates of these behaviors were shown to increase in four trained subjects using a within-subject multiple-baseline experimental design. The generality of the behavior change was investigated by integrating three untrained subjects with the trained subjects in a setting free of adult-imposed contingencies and through a series of follow-up observations. Three trained subjects evidenced collateral increases in the generalization setting on at least one other behavior when training in smiling was conducted. One trained subject showed generalization session increases for each behavior when training was conducted to increase that behavior. All three untrained subjects demonstrated increased rates of smiling and sharing when interventions were conducted to increase those behaviors with the trained subjects. There was no appreciable generalization of verbal complimenting by either the trained or the untrained subjects. Both trained and untrained subjects generally maintained their increased rates of smiling, sharing, and positive physical contacting across four weeks of follow-up observations.  相似文献

Reading achievement depends in part on children's ability to employ strategies to monitor their comprehension, that is on children's use of metacognitive skills. An experimental intervention program created to foster such skills was evaluated. The story grammar training was designed to increase both strategic reading behavior and explicit, observable comprehension monitoring. Fourth-grade (N = 20) and fifth-grade (N = 16) children were randomly assigned to experimental and control groups. Maintenance was examined using free and probed oral recall, notetaking, and summarization of brief narrative and expository texts. Generalization was assessed through free and probed written recall of a lengthy text, which required both strategic reading and summarization skills for adequate comprehension. Skill acquisition was clearly demonstrated; trained readers were able to recall and summarize passages better than untrained readers. The evidence for generalization was more equivocal: although trained readers' free recall was significantly better than that of untrained readers, their probed recall was not. Provision of metacognitive skills that promote active comprehension monitoring, then, appears to provide children with the tools needed for independent reading. Programs designed to provide such skills may aid efforts to prevent reading failure.  相似文献

Role-play generalization of newly acquired assertive behavior was assessed across different response situations in a clinical outpatient sample. Prior to assertive training, subjects completed two paper-and-pencil inventories and a series of role-play situations. Behavioral role-play scenes included four response forms: making requests, expressing affection, standing up for rights, and expressing displeasure. Subjects were randomly assigned to treatment or test-retest conditions and the treatment subjects received six 2-hr sessions of assertion training using modeling, behavior rehearsal, instruction, positive reinforcement, assignedin vivo homework, bibliotherapy, and daily recordings of assertive behavior. Posttreatment, subjects completed the paper-and-pencil measures, trained role-play scenes, and a set of dissimilar untrained scenes requiring different response forms (giving compliments, receiving compliments; refusing unreasonable requests and expressing justified anger). Videotapes were rated blindly and in random order at the conclusion of the study by trained judges. Treatment and test-retest subjects were equivalent prior to training. Posttreatment for the two groups differed in self-report, role-play behavior in trained situations, and role-play behavior in untrained dissimilar situations (allp<.001). MANOVA with repeated measures confirmed that trained and generalization role-play scenes were quantitatively, as well as qualitatively, different, confirmed that treatment and test-retest subjects exhibited different performance levels posttreatment on both trained and generalization scenes, and revealed four significant interactions (allp<.001). Implications of the interactions are discussed. Canonical correlation revealed that subjects displayed significant commonality in their behavioral profiles across different response forms. The findings indicate that complex training resulted in generalization from trained situations to untrained and dissimilar generalization scenes for the clinical outpatient sample.  相似文献

Three retarded children were trained, using prompting and reinforcement procedures, to respond correctly to three categories of prepositional requests: “put the___ next to the___”, “put the___under the___”, and “put the___on top of the___”. Training sessions were alternated with probe sessions throughout the study. During training, a child was trained to respond to one request (e.g., “put the doll next to the cup”); during probing, the child was tested for generalization of this training to untrained requests. Responses to untrained requests were never prompted nor reinforced. The results showed that, as requests from one category were trained, the children's responses to the untrained requests of that category became increasingly correct. As discriminations among two or more categories were trained, the children's responses to the untrained requests of those categories also became increasingly correct. Thus, the methods employed appear to be successful in training generalized receptive discrimination among prepositional categories and possibly can be utilized in training other generalized receptive language skills.  相似文献

Matrix training consists of planning instruction by arranging components of desired skills across 2 axes. After training with diagonal targets that each combine 2 unique skill components, responses to nondiagonal targets, consisting of novel combinations of the components, may emerge. A multiple‐probe design across participants was used to evaluate matrix training with known nouns (e.g., cat) and verbs (e.g., jumping) with 5 children with autism spectrum disorders (ASD). Following baseline of Matrix 1 and a generalization matrix, diagonal targets within Matrix 1 were trained as noun–verb combinations (e.g., cat jumping). Posttests showed recombinative generalization within Matrix 1 and the generalization matrix for 4 participants. For 1 participant, diagonal training across multiple matrices was provided until correct responding was observed in the generalization matrix. Results support the use of matrix training to promote untrained responses for learners with ASD and offer a systematic way to evaluate the extent of generalization within and across matrices.  相似文献

A 7-yr-old bilingual boy of normal intelligence, judged by his school to be deficient in carrying out complex requests, was trained to comply with five-component instructions, e.g., “Give me/the chip/behind/the block/on blue”. Three interchangeable words or phrases were used for each component. Training proceeded in stages. First, the child was trained to identify all individual objects and actions; then to carry out requests involving only the first component, then the first two, then three, etc. On every trial, the visual setting permitted every possible response in the set. A test for generalization to nonreinforced instructions was given at each stage by giving no feedback for all instructions that included one preselected phrase. The phrase selected at each stage was one of the three that was introduced at that stage. As a further test for generalization, nonreinforced instructions were also given that included one additional component: the next to be trained (Probes Ahead). As a test for generalization across settings and instructions, several five-component instructions were presented each session in an unused classroom. These instructions used phrases, most of which were different from those being trained, and which referred to familiar classroom objects. Results showed: acquisition occurred for each stage of training, including the full five-component instruction; almost complete generalization of responding occurred to the subset of nonreinforced instructions; little or no generalization occurred to the Probes Ahead, where an additional untrained component was included; and little or no generalization was seen to the five-component classroom instructions, until training began on the five-component instructions in the training sessions. Performance was also examined for each component. Results showed that when a new component was introduced, correct performance to previously trained components declined, and was little if any superior to performance on the new component. In summary, transfer was found to untrained sentences of the same form as those being trained, even in another setting, where most of the components were different; but poor transfer was found to more complex sentences, and performance declined for previously trained components during training of a more complex sentence. Some features of the training procedure that may have affected the degree and form of transfer were discussed: the necessity for prior training in an appropriate response to the component phrases, the importance of intermixing of reinforced and nonreinforced trials, and the effects of the abruptness with which more complex sentence forms were introduced.  相似文献

Although Piaget emphasized the importance of negation in equilibration theory, few data are available pertaining to children's use of Grouping II (Gr. II) logic, which relies on negation. Three approaches to assessing Gr. II capability are reviewed in light of Piaget's (1949, Traité de logique: Essai de logistique opératoire, Paris: Colin) discussion of Gr. II. The paper describes a new task to assess three aspects of Gr. II thought: (a) naming secondary classes, (b) comparing a secondary class with a primary class contained within it, and (c) reasoning about vicariance relationships. An experimental group of third graders trained to use Gr. II logic performed significantly better on post-test tasks than did an untrained control group. Training included rule instruction, evaluative and informative feedback, and manipulative activities.  相似文献

Six students with moderate and severe disabilities were taught generalized purchasing skills through the use of videotape modeling in one, two, or three stores and in vivo instruction within one store. Training was conducted within three orders of treatments: (a) in vivo instruction followed by videotape training, (b) videotape training followed by in vivo instruction, and (c) concurrent videotape and in vivo instruction. Generalization probes were conducted in stores that were the same as those modeled on videotape, untrained stores that were infrequently probed (and never modeled on tape or taught directly), and novel stores that were probed only once after training. Results indicated the production of generalized purchasing skills by the students who received concurrent training and by the students who received sequential training. Videotape and in vivo training in isolation did not lead to generalized shopping skills. The results are discussed in terms of investigating the possible role of verbalization during videotape training on generalized responding and the effects of multiple probe interventions on inadvertent learning of critical skills.deceased.  相似文献

We examined the generalized effects of training children to fluently blend phonemes of words containing target vowel teams on their reading of trained and untrained words in lists and passages. Three second-grade students participated. A subset of words containing each of 3 target vowel teams (aw, oi, and au) was trained in lists, and generalization was assessed to untrained words in lists, trained and untrained words in target passages, and novel words in generalization passages. A multiple probe design across vowel teams revealed generalized increases in oral reading accuracy for target words presented in both lists and passages for all 3 students on 2 vowel teams and for 1 student on all 3 vowel teams. Generalized increases in oral reading fluency in both lists and passages were found for all 3 students on the vowel team that was trained to a fluency criterion, with two students showing increases prior to training on the other two vowel teams. Implications of these results for building fluency in prerequisite phonemic awareness skills as an intervention for promoting generalized oral reading fluency are discussed.  相似文献

Matrix training is a generative approach to instruction in which words are arranged in a matrix so that some multiword phrases are taught and others emerge without direct teaching. We taught 4 preschoolers with autism to follow instructions to perform action-picture combinations (e.g., circle the pepper, underline the deer). Each matrix contained 6 actions on 1 axis and 6 pictures on the other axis. We used most-to-least prompting to train the instructions along the diagonal of each matrix and probed the untrained combinations. For 2 participants, untrained responding emerged after the minimum amount of training. The other 2 participants required further training before untrained combinations emerged. At the end of the study, 3 of the 4 participants performed the trained actions with previously known pictures, letters, and numbers. This study demonstrated that matrix training is an efficient approach to teaching language and literacy skills to children with autism.  相似文献

Current theories of object recognition in human vision make different predictions about whether the recognition of complex, multipart objects should be influenced by shape information about surface depth orientation and curvature derived from stereo disparity. We examined this issue in five experiments using a recognition memory paradigm in which observers (N = 134) memorized and then discriminated sets of 3D novel objects at trained and untrained viewpoints under either mono or stereo viewing conditions. In order to explore the conditions under which stereo-defined shape information contributes to object recognition we systematically varied the difficulty of view generalization by increasing the angular disparity between trained and untrained views. In one series of experiments, objects were presented from either previously trained views or untrained views rotated (15°, 30°, or 60°) along the same plane. In separate experiments we examined whether view generalization effects interacted with the vertical or horizontal plane of object rotation across 40° viewpoint changes. The results showed robust viewpoint-dependent performance costs: Observers were more efficient in recognizing learned objects from trained than from untrained views, and recognition was worse for extrapolated than for interpolated untrained views. We also found that performance was enhanced by stereo viewing but only at larger angular disparities between trained and untrained views. These findings show that object recognition is not based solely on 2D image information but that it can be facilitated by shape information derived from stereo disparity.  相似文献

Access to behavior-analytic professionals who can implement interventions like discrete-trial instruction (DTI) may be limited for families living in rural communities. We trained four rural parents of children with autism to implement DTI accurately with a confederate using in vivo behavioral skills training. The DTI skills that parents demonstrated with a confederate generalized to working with their children. We then assessed whether periodic supervision during videoconferencing maintained parents’ DTI skills following training. Parents accurately implemented untrained DTI programs with their children and maintained accurate implementation over several months of remote supervision occurring twice a week, weekly, and biweekly. Videoconferencing may be an effective way for individuals responsible for direct implementation to maintain contact with behavior analysts who are not locally accessible.  相似文献

Given the increasing complexity of the tasks and skills needed in modern society, developing effective training strategies is of tremendous practical importance. Furthermore, training that improves performance of both trained and untrained tasks would be highly efficient. In the present study, we examined how directed training contributes to skill acquisition, and more importantly, to engendering transfer of training to untrained tasks. Participants learned a complex video game for 30 h (Space Fortress, Donchin, Fabiani, & Sanders, 1989) using one of two training regimens: Hybrid Variable-Priority Training (HVT), with a focus on improving specific skills and managing task priority, or Full Emphasis Training (FET) in which participants simply practiced the game to obtain the highest overall score. We compared game performance, retention of training gains, and transfer of training to untrained tasks as a function of the training regimen. Compared to FET, HVT learners reached higher levels of mastery on the game and HVT was particularly beneficial for initially poor performing participants. This benefit persisted seven months after training. However, contrary to expectation, both HVT and FET were unsuccessful in producing transfer to untrained tasks compared to a group that received limited game experience, suggesting that directed training and practice can produce task-specific improvements, but improvements do not necessarily transfer from trained to untrained tasks.  相似文献

Social skills training was administered to three (one male and two female) chronic schizophrenic patients in a Partial Hospitalization Service. Treatment consisted of instructions. feedback and modeling, and was administered in 25. 26 and 31 sessions, respectively, for the three patients. Target behaviors were identified for each patient based on his/her responses to role-played interactions involving male and female partners in situations requiring commendatory or hostile assertion. Five to seven target behaviors were selected for each subject and were treated sequentially in a multiple baseline format. Skills training was highly successful for the two female patients but was only partially effective for the male patient. Two forms of generalization measures were included, indicating that the effects of training generalized from trained to untrained, and trained to novel role-played interactions. Follow-up assessments for the two female patients indicated that most of the effects persisted over 8–10-week post-treatment periods.  相似文献

Cognitive training can allow patients with Alzheimer’s disease (AD) to reinforce individual cognitive abilities. In the present case study, we investigated the generalizability of trained cognitive skills to novel tasks, and their stability over time.

One AD patient underwent a structured cognitive training using the GEO (Geographical Exercise for cognitive Optimization) task, whereas eight AD patients underwent a control cognitive intervention. Participants’ performances on the GEO task, on a similar untrained cognitive task, and on a different untrained cognitive task were recorded before and after the intervention, and at the follow-up. On both the trained and the similar untrained tasks patients’ and controls’ performance significantly differed from one another. Our preliminary evidence shows that a cognitive training could allow patients to improve and maintain their performance not only on the trained task, but also on a similar task.  相似文献

It was predicted that trained observers would detect deception more accurately than untrained observers. More specifically, it was predicted that the highest deception detection accuracy would be found among trained observers judging the veracity of low self-monitors and unrehearsed liars, whereas the lowest detection accuracy would be found among untrained observers judging the veracity of high self-monitors and rehearsed deceivers. It also was hypothesized that the discrepancy between observers‘actual ability to detect deception and their certainty in the accuracy of their judgments would be smaller for trained observers than for untrained observers. Observers trained to detect deception used six behavioral cues based on research by deTurck and Miller (1985): (a) message duration, (b) response latency, (c) adaptors, (d) pauses, (e) nonfluencies, and (f) hand gestures. Results confirmed both hypotheses.  相似文献

The effects of training on leadership skills and group processes in cancer and anorexic self-help groups are investigated. Three components of the study are reported. Firstly, an observational case-study of each type, of group was conducted to investigate the nature of the leadership input. Secondly, a Self-Help Questionnaire based on Lieberman's classification of leadership skills was administered to members of eight self-help groups to compare the experiences of groups with trained and untrained leaders. Thirdly, group members completed a Helpful Factors Questionnaire based on Yalom's analysis of group processes. The observational case-study revealed significant differences between the trained and untrained leaders in that, unlike the trained leader, the untrained leader clearly dominated the group. Results from the Self-Help Questionnaire showed that trained leaders scored higher on Caring and Emotional Stimulation but lower on Attribution of Meaning. Member satisfaction, however, was similar in the two types of group. Results from the Helpful Factors Questionnaire showed that most of the helpful factors were seen similarly by the two types of group, though differences were found concerning the relative rankings of both Guidance and Altruism. It is concluded that some degree of training of group leaders could be usefully incorporated into the self-help movement.  相似文献

This study investigated the effects of written text and pictorial cuing with supplemental video feedback on the social communication of 5 students with autism and social deficits. Two peers without disabilities participated as social partners with each child with autism to form five triads. Treatment was implemented twice per week and consisted of 10 min of systematic instruction using visual stimuli, 10 min of social interaction, and 10 min of self‐evaluation using video feedback. Results showed increases in targeted social communication skills when the treatment was implemented. Some generalized treatment effects were observed across untrained social behaviors, and 1 participant generalized improvements within the classroom. In addition, naive judges reported perceived improvements in the quality of reciprocal interactions. These findings support recommendations for using visually cued instruction to guide the social language development of young children with autism as they interact with peers without disabilities.  相似文献
