Abstract. René Descartes proposed an interactive dualism that posits an interaction between the mind of a human being and some of the matter in his or her brain. However, the classical physical theories that reigned during the eighteenth and nineteenth centuries are based exclusively on the material/physical part of Descartes' ontology, and they purport to give, in principle, a completely deterministic account of the physically described properties of nature, expressed exclusively in terms of these physically described properties themselves. Orthodox contemporary physical theory violates this condition in two separate ways. First, it injects random elements into the dynamics. Second, it requires psychophysical events, called Process 1 interventions by John von Neumann. Neither the content nor the timing of these events is determined, even statistically, by any known law. Orthodox quantum mechanics considers these events to be instigated by choices made by conscious agents. This quantum conception of the mind‐brain connection allows many psychological and neuropsychological findings associated with the apparent physical effectiveness of our conscious volitional efforts to be explained in a causal and practically useful way. According to this quantum approach, conscious human beings are invested with degrees of freedom denied to the mechanistic automatons to which classical physics reduced us. 相似文献

We used a systems perspective to examine relationships between adolescents’ perceptions of overall family system functioning and selected parental behaviors. Self-report questionnaire data from 160 ninth and tenth grade students were analyzed using MANCOVA and discriminant analysis. The results showed two parental behaviors, support and monitoring distinguished between types of overall family system functioning. Adolescents in balanced and moderately balanced overall family functioning reported greater parental support, while adolescents in balanced and extreme overall family functioning reported greater parental monitoring. We present the implications of our findings for parent education and assessment. 相似文献

The neural consequences of semantic richness: when more comes to mind, less activation is observed 总被引:1,自引:0,他引:1
Some concepts have richer semantic representations than others. That is, when considering the meaning of concepts, subjects generate more information (more features, more associates) for some concepts than for others. This variability in semantic richness influences responses in speeded tasks that involve semantic processing, such as lexical decision and semantic categorization tasks. It has been suggested that concepts with richer semantic representations build stronger attractors in semantic space, allowing faster settling of activation patterns and thus faster responding. Using event-related functional magnetic resonance imaging, we examined the neural activation associated with semantic richness by contrasting activation for words with high and low numbers of associates in a semantic categorization task. Results were consistent with faster semantic settling for words with richer representations: Words with a low number of semantic associates produced more activation than words with a high number of semantic associates in a number of regions, including left inferior frontal and inferior temporal gyri. 相似文献

The results of a functional analysis of problem behavior and a paired-choice assessment were compared to determine whether the same social reinforcers were identified for problem behavior and an appropriate response (time allocation). The two assessments were conducted in classroom settings with 4 adolescents with mental retardation who engaged in severe problem behavior. Each student's classroom teacher served as the therapist for all phases of assessment. The two assessment procedures identified the same social reinforcers for problem and appropriate behavior for 3 of 4 participants. 相似文献

Two experiments investigated how the type and timing of feedback influence learning from a multiple-choice test. First, participants read 12 prose passages, which covered various general knowledge topics (e.g., The Sun) and ranged between 280 and 300 words in length. Next, they took an initial six-alternative, multiple-choice test on information contained in the passages. Feedback was given immediately for some of the multiple-choice items or after delay for other items. Participants were either shown the correct answer as feedback (standard feedback) or were allowed to keep answering until the correct answer was discovered (answer-until-correct feedback). Learning from the test was assessed on a delayed cued-recall test. The results indicated that delayed feedback led to superior final test performance relative to immediate feedback. However, type of feedback did not matter: discovering the correct answer through answer-until-correct feedback produced equivalent performance relative to standard feedback. This research suggests that delaying the presentation of feedback after a test is beneficial to learning because of the spaced presentation of information. 相似文献
