Visual processing breaks the world into parts and objects, allowing us not only to examine the pieces individually, but also to perceive the relationships among them. There is work exploring how we perceive spatial relationships within structures with existing representations, such as faces, common objects, or prototypical scenes. But strikingly, there is little work on the perceptual mechanisms that allow us to flexibly represent arbitrary spatial relationships, e.g., between objects in a novel room, or the elements within a map, graph or diagram. We describe two classes of mechanism that might allow such judgments. In the simultaneous class, both objects are selected concurrently. In contrast, we propose a sequential class, where objects are selected individually over time. We argue that this latter mechanism is more plausible even though it violates our intuitions. We demonstrate that shifts of selection do occur during spatial relationship judgments that feel simultaneous, by tracking selection with an electrophysiological correlate. We speculate that static structure across space may be encoded as a dynamic sequence across time. Flexible visual spatial relationship processing may serve as a case study of more general visual relation processing beyond space, to other dimensions such as size or numerosity. 相似文献

The objectives of the present study were to assess the effects of online cognitive behavioural therapy (CBT) training for therapists on measures of CBT knowledge, skills, confidence, and utilisation; to determine what differences might exist between a group supported by regular telephone contact and an independent group who undertook online training without additional support; and to determine the acceptability of CBT online training among rural and remote mental health professionals. Mental health practitioners were randomly allocated to a supported training group (six sessions of 15‐min support) or an independent group. They undertook a 12‐week online CBT training program. The two groups showed similar gains on an objective test of knowledge of CBT, and on self‐report measures of knowledge, skills, confidence levels, and utilisation of skills. However, the supported training group had a significantly higher program completion rate than the independent group. Participants evaluated the program favourably. The results suggest that online CBT training represents a promising and cost‐effective approach to training the mental health workforce, and may be particularly attractive for those who live in regional, rural, and remote communities. A challenge is to determine the most cost‐effective ways to enhance program completion rates and trainee skills. 相似文献

In recent years research on automatic imitation has received considerable attention because it represents an experimental platform for investigating a number of interrelated theories suggesting that the perception of action automatically activates corresponding motor programs. A key debate within this research centers on whether automatic imitation is any different than other long-term S-R associations, such as spatial stimulus-response compatibility. One approach to resolving this issue is to examine whether automatic imitation shows similar response characteristics as other classes of stimulus-response compatibility. This hypothesis was tested by comparing imitative and spatial compatibility effects with a two alternative forced-choice stimulus-response compatibility paradigm. The stimulus on each trial was a left or right hand with either the index or middle finger tapping down. Speeded responses were performed with the index or middle finger of the right hand in response to the identity or the left-right spatial position of the stimulus finger. Two different tasks were administered: one that involved responding to the stimulus (S-R) and one that involved responding to the opposite stimulus (OS-R; i.e., the one not presented on that trial). Based on previous research and a connectionist model, we predicted standard compatibility effects for both spatial and imitative compatibility in the S-R task, and a reverse compatibility effect for spatial compatibility, but not for imitative compatibility, in the OS-R task. The results from the mean response times, mean percentage of errors, and response time distributions all converged to support these predictions. A second noteworthy result was that the recoding of the finger identity in the OS-R task required significantly more time than the recoding of the left-right spatial position, but the encoding time for the two stimuli in the S-R task was equivalent. In sum, this evidence suggests that the processing of spatial and imitative compatibility is dissociable with regard to two different processes in dual processing models of stimulus-response compatibility. 相似文献

In three experiments, we investigated the roles of recollection and familiarity in the production effect—the finding that
words read aloud are remembered better than words read silently. Experiment 1, using the remember/know procedure, and Experiment 2, using the receiver operating characteristic procedure, converged in demonstrating that production enhanced both recollection
and familiarity. Experiment 3 supported the role of recollection by demonstrating that specific episodic information—that is, whether a word had been studied
aloud or silently—was stronger for items studied aloud. These findings fit with an explanation of the production effect as
hinging on two factors: greater recollection of distinctive information from the study episode, and more familiarity due to
greater attention allocated to the material studied aloud. 相似文献

Previous research suggests that demographic factors are important correlates of cognitive functioning in African Americans; however, less attention has been given to the influence of personality. The present study explored how dimensions and facets of personality predicted individual variability in cognition in a sample of older African Americans from the Baltimore Study of Black Aging. Cognition was assessed by verbal learning and attention/working memory measures. Personality was measured by the NEO Personality Inventory-Revised. Linear regressions controlling for demographic factors showed that Neuroticism, Openness, and Agreeableness were significant regression predictors of cognitive performance. Individual facets of all five personality dimensions were also associated with cognitive performance. These findings suggest personality is important in understanding variability in cognition among older African Americans. 相似文献

Person-environment fit (P-E fit) was initially espoused as an important construct in the field of community psychology; however, most of the theoretical and empirical development of the construct has been conducted by the industrial/organizational (I/O) psychologists and business management fields. In the current study, the GEFS-a P-E fit measure that was developed from organizational perspectives on fit-was administered to 246 attendees of an annual convention for residents and alumni of Oxford House, a network of over 1,400 mutual-help addiction recovery homes. The authors conducted confirmatory factor and convergent construct validity analyses with the GEFS. The results suggested that the theoretical factor structure of the measure adequately fit the data and provided limited support for the measure's validity. Sufficient supply of resident needs by the Oxford House and similarity between residents and their housemates predicted satisfaction with the recovery home, but only perceived similarity to housemates predicted how long residents intended to stay in the Oxford Houses. 相似文献
