Two experiments investigated the effects of landmarks and body-based information on route knowledge. Participants made four
out-and-back journeys along a route, guided only on the first outward trip and with feedback every time an error was made.
Experiment 1 used 3-D virtual environments (VEs) with a desktop monitor display, and participants were provided with no supplementary
landmarks, only global landmarks, only local landmarks, or both global and local landmarks. Local landmarks significantly
reduced the number of errors that participants made, but global landmarks did not. Experiment 2 used a head-mounted display; here, participants who physically walked through the VE (translational and rotational body-based
information) made 36% fewer errors than did participants who traveled by physically turning but changing position using a
joystick. Overall, the experiments showed that participants were less sure of where to turn than which way, and journey direction
interacted with sensory information to affect the number and types of errors participants made. 相似文献

The time taken to decide whether a character is shown in its mirror or normal version has been shown to increase approximately linearly with the angular departure from an up-right position. Additionally, in some studies, decisions took longer for clockwise tilted characters than for counterclockwise tilted ones. Other studies do not report the latter effect. We argue that inconsistencies across studies are caused by variance in participants' strategies. The task employed here was specifically designed to bring these strategies and thereby the direction of rotation under experimental control. From the EEG recorded during the rotation period, we extracted an event-related slow potential whose amplitude is sensitive to the amount of mental rotation. In both strategy conditions, the slow potential's amplitude was lower for clockwise than for counterclockwise rotations. We take this as evidence that mental rotation of alphanumeric characters is easier in a clockwise than in a counterclockwise direction. 相似文献

Visual working memory (VWM) is a core construct in the cognitive (neuro‐)sciences, assumed to serve as a hub for information exchange and thus supporting a multitude of cognitive functions related to processing visual information. Here, we give an introduction into key terms and paradigms and an overview of ongoing debates in the field, to which the articles collected in this Special Issue on ‘Current Directions in Visual Working Memory Research’ contribute. Our aim is to extract, from this overview, some ‘emerging’ theoretical insights concerning questions such as the optimal way to examine VWM, which types of mental representations contribute to performance on VWM tasks, and how VWM keeps features from the same object together and apart from features of concurrently maintained objects (the binding problem). 相似文献

Visual working memory (VWM) is a central bottleneck in human information processing. Its capacity is most often measured in terms of how many individual‐item representations VWM can hold (k). In the standard task employed to estimate k, an array of highly discriminable colour patches is maintained and, after a short retention interval, compared to a test display (change detection). Recent research has shown that with more complex, structured displays, change‐detection performance is, in addition to individual‐item representations, supported by ensemble representations formed as a result of spatial subgroupings. Here, by asking participants to additionally localize the change, we reveal indication for an influence of ensemble representations even in the very simple, unstructured displays of the colour‐patch change‐detection task. Critically, pure‐item models from which standard formulae of k are derived do not consider ensemble representations and, therefore, potentially overestimate k. To gauge this overestimation, we develop an item‐plus‐ensemble model of change detection and change localization. Estimates of k from this new model are about 1 item (~30%) lower than the estimates from traditional pure‐item models, even if derived from the same data sets. 相似文献

Ambiguity has long been used as a probe into visual processing. Here, we describe a new dynamic ambiguous figure-the chimeric point-light walker--which we hope will prove to be a useful tool for exploring biological motion. We begin by describing the construction of the stimulus and discussing the compelling finding that, when presented in a mask, observers consistently fail to notice anything odd about the walker, reporting instead that they are watching an unambiguous figure moving either to the left or right. Some observers report that the initial percept fluctuates, moving first to the left, then to the right, or vice versa; others always perceive a constant direction. All observers, when briefly shown the unmasked ambiguous figure, have no difficulty in perceiving the novel motion pattern once the mask is returned. These two findings--the initial report of unambiguous motion and the subsequent 'primed' perception of the ambiguity--are both consistent with an important role for top-down processing in biological motion. We conclude by suggesting several domains within the realm of biological-motion processing where this simple stimulus may prove to be useful. 相似文献

Perceived control over development and subjective well-being: differential benefits across adulthood 总被引:5,自引:0,他引:5
The relationship between perceived control over development (PCD) and subjective well-being (SWB) across adulthood was examined in 3 studies. In Study 1, with 480 adults aged between 20 and 90 years, PCD was closely related to SWB. Chronological age moderated the associations between PCD and SWB beyond individual differences in health, intelligence, social support, and socioeconomic status. In the longitudinal Study 2, with 42 older adults, strong PCD was associated with increased positive affect only when desirable events had occurred previously. In Study 3, older adults experienced greater satisfaction when attributing attainment of developmental goals to their ability, whereas younger adults were more satisfied when attributing such successes to their own efforts. Findings point to adaptive adjustments of control perceptions to age-related actual control potentials across adulthood. 相似文献
