Do the laws of nature supervene on ordinary, non‐nomic matters of fact? Lange’s criticism of Humean supervenience (HS) plays a key role in his account of natural laws. Though we are sympathetic to his account, we remain unconvinced by his criticism. We focus on his thought experiment involving a world containing nothing but a lone proton and argue that it does not cast sufficient doubt on HS. In addition, we express some concern about locating the lawmakers in an ontology of primitive subjunctive facts and suggest that a ‘mixed’ metaphysics to the lawmaker question might be attractive. 相似文献

ObjectivesThe objectives of this research were a) to explore the applicability of ‘motivational climate’ research to early career athletes under the age of twelve, b) to re-examine the concept of ‘motivational climate’ in the light of recent scientific developments, and c) to concurrently study the influences of coaches, parents and peers on athletic motivation.Design and MethodUsing a qualitative design, 40 participants (7–11 years of age) from various sports were interviewed in focus groups, using a semi-structured format to investigate the roles played by coaches, parents, and peers in influencing athlete motivation. An inductive content analysis was conducted to determine which behaviours among these social agents influenced key motivational outcomes.FindingsThe analysis indicated that young athletes experience a motivational climate which shows consistencies with existing models of motivation; suggesting this population is worthy of further study. The influences of coaches related most strongly to the manner in which they perform their roles of instruction and assessment, whereas parents' influences were most salient in terms of the way they support the child's participation and learning. Both parents and coaches exerted influences through their leadership styles, affective responses and pre-performance behaviours. Peers influenced participants' motivation through competitive behaviours, collaborative behaviours, evaluative communications and through their social relationships.ConclusionsThis study provides an insight into the motivational climate experienced by young athletes and helps to delineate the different roles of social agents in influencing their motivation at this early stage of development. 相似文献

A central feature of many formal accounts of reading aloud, and of Coltheart and colleagues dual-route cascaded model in particular, is that activation across various modules is cascaded. Evidence is reviewed that this assumption is problematic in a particular context, along with a solution that involves thresholding the output of the letter level to the nonlexical routine. Consideration of the known effects of repetition leads to the prediction of a three-way interaction between stimulus quality, repetition, and lexicality in which repetition and stimulus quality interact when reading aloud exception words, but produce additive effects when reading aloud nonwords. The result of such an experiment confirms this prediction, and appears consistent with the localized dual-route model. Implications for other accounts are briefly noted. 相似文献

This research examined the associations between measures of sociotropic and autonomous personality, romantic attachment anxiety and avoidance, and corresponding attachment ratings across a range of different specific relationships with people whom participants regularly interacted (including romantic partners, friends, family members, and colleagues). Analyses using hierarchical linear modeling showed that sociotropy and autonomy were directly associated with respective ratings of relationship-specific anxiety and avoidance within non-romantic relationships. In contrast, domain-specific romantic attachment predicted relationship-specific attachment with romantic (but not non-romantic) partners, and, as hypothesized, mediated the associations between sociotropy and autonomy and relationship-specific attachment within this domain. Implications for the operationalization of sociotropy and autonomy as broad-bandwidth (personality-level) measures that assess more global summaries of regularities in the same dual dimensions identified in the attachment literature (i.e., attachment anxiety and avoidance) are discussed. 相似文献

Effects of agency on movement interference during observation of a moving dot stimulus 总被引:1,自引:0,他引:1
Stanley J Gowen E Miall RC 《Journal of experimental psychology. Human perception and performance》2007,33(4):915-926
Human movement performance is subject to interference if the performer simultaneously observes an incongruent action. It has been proposed that this phenomenon is due to motor contagion during simultaneous movement performance-observation, with coactivation of shared action performance and action observation circuitry in the premotor cortex. The present experiments compared the interference effect during observation of a moving person with observation of moving dot stimuli: The dot display followed either a biologically plausible or implausible velocity profile. Interference effects due to dot observation were present for both biological and nonbiological velocity profiles when the participants were informed that they were observing prerecorded human movement and were absent when the dot motion was described as computer generated. These results suggest that the observer's belief regarding the origin of the dot motion (human-computer generated) modulates the processing of the dot movement stimuli on their later integration within the motor system, such that the belief regarding their biological origin is a more important determinant of interference effects than the stimulus kinematics. 相似文献

Somatosensory processes subserving perception and action 总被引:2,自引:0,他引:2
The functions of the somatosensory system are multiple. We use tactile input to localize and experience the various qualities of touch, and proprioceptive information to determine the position of different parts of the body with respect to each other, which provides fundamental information for action. Further, tactile exploration of the characteristics of external objects can result in conscious perceptual experience and stimulus or object recognition. Neuroanatomical studies suggest parallel processing as well as serial processing within the cerebral somatosensory system that reflect these separate functions, with one processing stream terminating in the posterior parietal cortex (PPC), and the other terminating in the insula. We suggest that, analogously to the organisation of the visual system, somatosensory processing for the guidance of action can be dissociated from the processing that leads to perception and memory. In addition, we find a second division between tactile information processing about external targets in service of object recognition and tactile information processing related to the body itself. We suggest the posterior parietal cortex subserves both perception and action, whereas the insula principally subserves perceptual recognition and learning. 相似文献

According to attachment theory, insecure individuals respond to events in their romantic relationships in ways that sometimes can be destructive. The objective of this research was to examine how these responses may accumulate over repeated interactions to influence the quality of the relationship. Across three studies, participants were presented with a "Choose Your Own Adventure" dating story in which they made choices based on their partners' behaviors. In each study we found that attachment styles predicted the kinds of choices participants made at the outset of and throughout the story. Additionally, relationship satisfaction was related to the choices participants made throughout the fictional narrative, even in situations in which the partner's behavior was the same for all participants. 相似文献
