This article addresses the contingency-space analysis (Matthews, Shimoff, & Catania, 1987) of the verbal regulation of behavior. From an applied perspective, the conceptualization of the relationship between saying and doing Matthews et al. present may be more complex than is necessary. The central issue in correspondence investigations is a simple one: does correspondence between what people say and what they do occur? The focus of this paper is on the applied and clinical importance of the relationship between verbalizations and relevant behavior and the implications for future research. 相似文献

Lever pressing of children from three age groups (2½ to 4, 5 to 6½, and 7½ to 9 years) could produce reinforcers according to a fixed-interval 40-s schedule: (1) Some were instructed to respond at a high rate, others at a low rate, and (2) they were subsequently taught to provide their own spoken self-instructions consonant with the earlier, experimenter-supplied instructions. All subjects who received high-rate instructions responded at a steady, high rate, which was maintained following self-instructional training. The effects of low-rate instructions were directly related to the age of the children. The two older groups produced low-rate patterns, with the oldest children responding at very low rates; effects were least noticeable in the youngest age group. Following self-instructional training, all three groups showed adult-like low-rate behavior and the oldest children showed an improved ability to estimate the interval length. The results provide further evidence of the importance of language as a determinant of human behavior. 相似文献

The purpose of this study was to examine the relationship between receptive and productive language acquisition in developmentally disabled children. A single-subject operant methodology was employed to evaluate the effect of training in one mode on performance in the other mode. Noun labels for pictured objects were used as the unit of analysis. Six children with severe language deficits participated in the experiment. Each subject learning to identify a different set of five pictures in each of four successively administered training conditions. In the first condition, a set of pictures was trained in the productive mode. In the second condition, a different set was trained in the receptive mode. These training conditions were then repeated using two additional sets of pictures. Training was done using reinforcement for correct responses and prompting for incorrect responses. Nonreinforced probes were conducted throughout training to assess performance in the untrained mode. The pictures in each set were trained successively so that transfer across the language modes could be studied separately for each response trained. All subjects successfully met the criteria for learning each picture set in both the receptive and productive training conditions. The probe data showed that opposite-modality performance improved as a function of both types of training, although performance levels differed. After productive training, five of six subjects' performance was highly accurate on receptive probes. By contrast, receptive training resulted in limited correct productive performance. Transfer from receptive training was negatively related to subjects' use of extra-experimental labels on productive probe trials. In addition to these competing response errors, subjects frequently made articulation errors. The findings suggest that for retarded children similar to those studied here, productive training will be sufficient to establish accurate receptive performance on vocabulary tasks. However, receptive training does not appear to be either a necessary or a sufficient condition for productive performance. The results do not support the reception-then-production training sequence based on normal language development. 相似文献

A single-subject multiple-baseline design using within- and across-subject replication was employed to study the acquisition of expanded “agent-action-object” sentences and the spontaneous generation of this form in the natural environment. Three young language-delayed subjects were trained to describe various agent-action-object relationships with a five-element syntactical form. The language training strategy was a synthesis of the developmental-psycholinguistic and behavioral models. Dynamic interactions between familiar persons and objects were the stimulus events that the children mapped. A five-element syntactical form, previously absent from the children's language repertoires, was trained during individual sessions. Concurrent with baseline, training, and followup, each subject's language was monitored in another setting, the classroom during free play. After onset of training, the core elements of the complex syntactic form were spontaneously emitted by the child in its natural environment. The free-play data reflect individual differences in the emergence and frequency of each child's spontaneous use of the agent-action-object form. The acquisition and maintenance of the specific lexicon and syntax trained were tested by posttraining probes and responses to videotape presentations. These probes revealed generalization and maintenance of both the lexical and syntactical forms acquired in treatment. The main purpose of any language-training procedure should be to provide language that is functional for the child in the natural environment. This study, which documented the spontaneous usage of the core agent-action-object syntactical form in the natural environment, effectively trained a functional syntactical rule. 相似文献

The acquisition of prepositional motor responses in three handicapped preschool children was analyzed for three pairs of prepositions. Generalization of prepositional knowledge at each stage of acquisition was assessed by a series of probe trials. In addition, an analysis of the control of prepositional responses when objects of the preposition (OP) and direct objects (DO) were relevant cues was conducted. The effect of this object-cue procedure, as well as a specially devised prompting technique on acquisition, was also determined. Results indicated substantial control by OPs whenever this cue was relevant, but this did not affect acquisition of prepositional concepts when these cues were eliminated. Analysis of the probe data and the prompting technique suggested various ways in which instructional programs for teaching prepositional knowledge to handicapped children could be constructed in a simple and efficient manner. 相似文献

The performances of two infants less than one year old were investigated on fixed-interval schedules. When the infants touched a cylinder either music or food was presented according to fixed-interval schedules ranging in value from 10 to 50 seconds. With respect to two principal criteria, namely, pattern of responding and sensitivity to the schedule parameter, the subjects' behavior closely resembled that of animals but differed markedly from that of older children and adults. Negatively accelerated responding in the course of the fixed interval in the early sessions gave way to a scalloped pattern, consisting of a pause after reinforcement followed by an accelerated response rate. This scalloped pattern was the final form of responding on all schedule values. Analysis of data after performance had stabilized showed that postreinforcement pause was a negatively accelerated increasing function, and running rate (calculated after excluding the postreinforcement pause) was a declining function, of schedule value. On each schedule, the durations of mean successive interresponse times declined in the course of the fixed interval and were directly related to schedule value. The results supported Lowe's (1979) suggestion that verbal behavior may be responsible for major differences in the schedule performance of older humans and animals. 相似文献

Abstract: Two experiments were carried out to investigate the factors that produce the misinformation effect (Loftus, 1979a). Experiment 1 of the present study using the visual recognition test was a replica of Experiment 1 of Loftus, Miller, and Burns (1978). The misinformation effect was not found. Experiment 2 differed from Experiment 1 in the following respects: the modality of recognition test was varied between visual and verbal; memorableness (ease of memorization) of the critical objects was varied. The results of Experiment 2 suggest that the original visual memory might be more likely to be recovered with a visual recognition test than with a verbal recognition test, and that the postevent information would not necessarily interfere effectively with memory of an original object of too high or low memorableness, while it works well on objects of intermediate memorableness. 相似文献

Nicotinic receptor dysfunction and impaired semantic memory occur early in Alzheimer's disease patients (AD). Previous research implied that nicotine's ability to enhance alertness, arousal, and cognition in a number of nonclinical populations was a function of its ability to stimulate CNS nicotinic cholinergic receptors. In this study it was hypothesized that transdermal administration of nicotine would increase both regional cerebral glucose metabolism (rCMRglc) and semantic memory (as assessed by verbal fluency). Two mild AD and two elderly controls underwent positron emission tomography scanning during a double blind nicotinic agonist verbal fluency challenge procedure. rCMRglc increases occurred in both AD patients, but not controls. In the two AD patients, verbal fluency scores increased by an average of 17%. One elderly control's verbal fluency increased, and the other decreased. These findings suggest that nicotine's effect on metabolism and verbal fluency is due to its ability to stimulate the cholinergic system. 相似文献

One of the primary intents of inclusion is the maximization of interaction between persons with and without disabilities. The purpose of this study was to analyze the verbal responding that peers directed toward adolescents with behavioral disorders and, to this effect, several comparisons were made: verbal responding of peers directed toward adolescents with behavioral disorders was compared to verbal responding of peers directed toward regular class adolescents; verbal responding of peers directed toward the same adolescents with behavioral disorders was compared across their self-contained and integrated settings; and verbal responding of peers directed toward adolescents with behavioral disorders in integrated settings was compared to verbal responding of peers directed toward regular class adolescents. Data, collected in real time using portable microcomputers, focused on positive, negative, and neutral social responding and positive, negative, and neutral academic responding. All verbal responding of peers directed toward 14 adolescents with behavioral disorders and 14 regular class peers was recorded. Data were analyzed by group and setting, as well as by social or academic content. Results of the study support inclusion, with high levels of peer responding directed toward adolescents with behavioral disorders in integrated classrooms. Almost all peer responding was positive or neutral in content. Results were discussed as they related to placement of students, social skills training, and previous research. 相似文献
