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

For the case of a single criterion a method is already available for determining the optimal distribution of testing time for a battery of predictors, assuming that intercorrelation, validity, and reliability data are available for predictors of arbitrary lengths. In this article a modification and generalization of the method is presented for the case of differential prediction involving a number of criterion variables. A numerical example is given to illustrate the method, after which the mathematical rationale is outlined.This research was carried out under Contract Nonr-477(08) between the University of Washington and the Office of Naval Research. Most of the computations were carried out by Robert Dear, Charlotte MacEwan, and Donald Mills. Much credit is due the typist, Elizabeth Cross. Supervision of both computational and editorial activities was provided by William Clemans. To each of these able contributors I am deeply grateful.  相似文献

In the present study in 20 healthy subjects, event-related potentials (ERPs) were used to investigate the identification of picture stimuli. Each of 36 landscape pictures and 36 scrambled pictures was presented by a tachistoscope repeatedly until the subject made an identification response. Presentation of one picture was finished after 12 exposures. On the average, landscapes were identified after 5.8 ± 0.4 exposures; identification responses to scrambles were always wrong and occurred after 11.8 ± 0.1 exposures. Latencies and amplitude measures were assessed for P2, P3, N400, and the slow wave (SW). Changes in P2 across stimulus presentations did not differ between landscapes and scrambles excluding this component from being indicative for the processing of stimulus meaning. Amplitude of P3 generally declined across presentations, but increased prior to identification for landscape pictures. N400 rapidly declined across presentations of landscapes, but less rapidly for scrambles. The SW increased across stimulus presentations. This increase was more pronounced for landscape than scrambled pictures. The pattern of ERP changes can be interpreted in a framework of a stepwise inhibition of spreading activation within semantic memory with progressing picture identification.  相似文献

In a paired associate learning task, subjects responded to each presentation of a nonsense syllable by typing both a three-letter associate and a rating of their confidence that this response was correct or incorrect. Average event-related potentials (ERPs) elicited by the subsequent presentation of the actual paired syllable varied with the interaction of confidence and trial outcome. A larger amplitude P300 was elicited by syllables that informed subjects that they were correct when they thought they were incorrect or that they were incorrect when they thought they were correct than by syllables that confirmed subjects expectations. That this average ERP result was indeed an effect on P300 amplitude, and not an artifact of single-trial variability in P30O latency, was confirmed with a trial-by-trial latency adjustment procedure. Consistent with findings from other tasks, P300 amplitude varied inversely with the subj ective probability of the ERP-eliciting events.  相似文献

We reflect on which traditional texts are suitable for the introduction into psychodynamic thinking for bachelor students in the faculty of psychology. We come to the conclusion that the use of works known and individually valued by the students from the world and/or trivial literature are suitable to allow students to carry out fictive preliminary conversations with their heroes from novels or films.  相似文献

In this study, we investigated how the birth of a very low birth weight preterm (VLBW) infant influences the mother–infant interaction at 3 months. We also focused on the impact of the infant's neurobiological risk and maternal anxiety, and their interaction. The comparison of the VLBW preterm sample (n = 79) with an external full‐term sample (n = 35) showed mother–infant interactions of the families with the preterm infant to be more vocally responsive during the interaction, but less facially responsive during the interaction. Additionally, higher levels of maternal anxiety were associated with preterm infants being less facially responsive in interaction with their mother. While neurobiological risk of the infant played a part in this association, with higher risk infants also being less facially responsive, the relationship with maternal anxiety and the mother–child interaction was stronger. How these findings may influence therapeutic interventions is discussed.  相似文献

In many countries, psychotherapy is increasingly influenced by standards of scientifically evaluated methods and disorder-specific approaches. Referring to the definitions of the Scientific Council for Psychotherapy in Germany (WBP) concerning the differentiation of modalities, methods and techniques, this article points out that clear distinctions between modalities and methods are increasingly vanishing; instead, the tendency, especially within behavior therapy, to integrate all scientifically based methods and techniques is prevailing. This trend runs parallel with a development away from ?disorder-specific“ to a ?disorder-oriented“ approach. Facing the fact that technical aspects explain a relatively small proportion of outcome variance in psychotherapy, research related to the quality of psychotherapists is recommended. In addition, ?empirically validated psychotherapists“ should receive guidelines instead of rules of action.  相似文献

Mentalization has mainly been studied in borderline patients but in this study the capacity for mentalization was investigated in patients suffering from chronic depression. Mentalization was measured with the reflective functioning scale (RFS) in patients with chronic depression (n=20) who started long-term psychoanalytic treatment and the results were compared to healthy controls. The results showed that global RF scores did not differ significantly between patients and controls. However, depressed patients had a lower RF score for depression relevant topics in comparison to the initial individual values. Furthermore, RF appears to be related to general psychological competence but unrelated to clinical parameters [Beck Depression Inventory (BDI) and symptom check list (SCL-90)]. Therapeutic outcome as measured with BDI and SCL-90 was not moderated by RF scores at baseline. Correlations between RF and the helping alliance questionnaire (HAQ) indicate that patients with higher RF scores establish a therapeutic alliance more easily than patients with lower RF scores.  相似文献
