We evaluated the effects of tact and listener instruction on the emergence of bidirectional intraverbal relations with 6 typically developing Brazilian children, using an adapted alternating treatment design with pretest and posttest probes. In listener instruction, participants selected pictures that corresponded to spoken foreign-language words. For tact instruction, children had to vocalize foreign words in the presence of the corresponding pictures. After meeting mastery criteria, bidirectional intraverbal tests assessed vocalizations in Portuguese (native language) following the presentation of the equivalent words in English (foreign language) and vice versa. Tact instruction consistently produced higher levels of emergent intraverbal responding compared to listener instruction, confirming results from previous studies. 相似文献

Previous studies have shown that music is a powerful means to convey affective states, but it remains unclear whether and how social context shape the intensity and quality of emotions perceived in music. Using a within-subject design, we studied this question in two experimental settings, i.e. when subjects were alone versus in company of others without direct social interaction or feedback. Non-vocal musical excerpts of the emotional qualities happiness or sadness were rated on arousal and valence dimensions. We found evidence for an amplification of perceived emotion in the solitary listening condition, i.e. happy music was rated as happier and more arousing when nobody else was around and, in an analogous manner, sad music was perceived as sadder. This difference might be explained by a shift of attention in the presence of others. The observed interaction of perceived emotion and social context did not differ for stimuli of different cultural origin. 相似文献

Synchronizing neural processes, mental activities, and social interactions is considered to be fundamental for the creation of temporal order on the personal and interpersonal level. Several different types of synchronization are distinguished, and for each of them examples are given: self‐organized synchronizations on the neural level giving rise to pre‐semantically defined time windows of some tens of milliseconds and of approximately 3 s; time windows that are created by synchronizing different neural representations, as for instance in aesthetic appreciations or moral judgments; and synchronization of biological rhythms with geophysical cycles, like the circadian clock with the 24‐hr rhythm of day and night. For the latter type of synchronization, an experiment is described that shows the importance of social interactions for sharing or avoiding common time. In a group study with four subjects being completely isolated together for 3 weeks from the external world, social interactions resulted both in intra‐ and interindividual circadian synchronization and desynchronization. A unique phenomenon in circadian regulation is described, the “beat phenomenon,” which has been made visible by the interaction of two circadian rhythms with different frequencies in one body. The separation of the two physiological rhythms was the consequence of social interactions, that is, by the desire of a subject to share and to escape common time during different phases of the long‐term experiment. The theoretical arguments on synchronization are summarized with the general statement: “Nothing in cognitive science makes sense except in the light of time windows.” The hypothesis is forwarded that time windows that express discrete timing mechanisms in behavioral control and on the level of conscious experiences are the necessary bases to create cognitive order, and it is suggested that time windows are implemented by neural oscillations in different frequency domains. 相似文献

The integration of theories and techniques is part of family therapists' daily practice, raising the need to understand which resources are used in this professional's clinical actions. Our aim is to reflect on the use of theoretical and technical resources by family therapists in their daily practice. We developed an inquiry process inspired by collaborative action research and social constructionism. Couple and family therapy sessions were conducted by two family therapists, and we developed subsequent dialogs with them focused on describing theoretical and technical inspirations for their actions. Next, we named four categories of actions in this process: exploratory actions, actions for the construction of relational visions, actions for the construction of communication, and actions for family orientation. The therapists-participants referred to many theoretical and technical resources that inspired their practice. For them, the choice of using one or another resource was based on the demands of the interactive moment, which involves their relational and embodied responses to what was experienced in the sessions. We argue that epistemological coherence is not something that guides the therapist's practice a priori, but something that can be achieved by talking about and reflecting on their actions. This article can contribute to clinical practice and training in family therapy by presenting an interesting reflexive process that can be useful to enhance practice in couple and family therapy (FAPESP, Process n. 2015/21316–1). 相似文献

Previous research has examined the factor structure of ADHD symptoms in adults using confirmatory factor analysis and there is mixed support for two-factor, three-factor, or more complex bifactor models. The current study re-examines these factor structures on the basis of not only overall model fit, but also criteria such as chi-square difference tests, invariance, reliability, and validity. Three datasets were pooled to form a total sample of 430 adults (50% female). Participants completed questionnaires assessing their ADHD symptoms, education, psychopathology, and parenting (the latter as validity variables). Although the bifactor models demonstrated the best fit, the reliability and construct replicability of specific factors in these models was poor. The three-factor model had good fit and demonstrated good reliability, validity, construct replicability, and some invariance across gender and dataset. Our results replicate previous studies that find superior fit for bifactor models. However, the superior statistical fit may reflect only the increased complexity of these models. The more parsimonious three-factor model may demonstrate stronger validity and clinical utility. 相似文献

The influence of dopaminergic replacement (DR) on gait in people with Parkinson's disease (PD) is well documented. However, little is known about the acute effects of dopamine on more complex locomotor tasks that require visual guidance to avoid obstacles during gait. The authors investigated the influence of DR on locomotor behavior in a task where movement planning and control might be challenged by the height of the obstacle. The PD group included patients diagnosed with idiopathic PD (n = 12), as well as healthy controls (n = 12). Patients walked and stepped over obstacles of different heights before (OFF) and after (ON) levodopa intake. Spatial adjustments were not modulated by DR, but the step time to perform these anticipatory gait adjustments was longer only in PD-OFF (compared with healthy controls) when approaching the highest obstacle, but not PD-ON. During the crossing phase, trail limb toe clearance of PD patients was shorter than healthy controls only during the OFF state. ON-OFF comparisons were significantly different only for the time to reach the lead foot clearance over the highest obstacle. In summary, DR partially improved movement slowness but did not directly affect movement amplitude of lower limb regulation in this gait task. 相似文献
