Spatial updating relies on an egocentric representation of space: Effects of the number of objects 总被引:1,自引:0,他引:1

Models of spatial updating attempt to explain how representations of spatial relationships between the actor and objects in
the environment change as the actor moves. In allocentric models, object locations are encoded in an external reference frame,
and only the actor’s position and orientation in that reference frame need to be updated. Thus, spatial updating should be
independent of the number of objects in the environment (set size). In egocentric updating models, object locations are encoded
relative to the actor, so the location of each object relative to the actor must be updated as the actor moves. Thus, spatial
updating efficiency should depend on set size. We examined which model better accounts for human spatial updating by having
people reconstruct the locations of varying numbers of virtual objects either from the original study position or from a changed
viewing position. In consistency with the egocentric updating model, object localization following a viewpoint change was
affected by the number of objects in the environment. 相似文献

The influence of adolescents' autonomy and relatedness to parents on romantic relationships was examined longitudinally over 5 years in 76 middle-class African American late adolescents (mean age = 18.43 years). Relatedness to parents in early adolescence led to longer duration and more supportive romantic relationships in late adolescence, but longer duration was concurrently associated with more negative romantic relationships. Cluster analyses yielded 3 profiles of early adolescent autonomy and relatedness; early adolescents who were high in relatedness and low in autonomy to parents in early adolescence reported longer duration romantic relationships in late adolescence than did adolescents who were moderate or high in relatedness and high in autonomy. The implications for romantic development in African American middle-class youth are discussed. 相似文献

Dion, Berscheid, and Walster (1972), in their seminal article, labeled the attribution of positive characteristics to attractive people the "beauty-is-good" stereotype. The stereotyping literature since then provides extensive evidence for the differential judgment and treatment of attractive versus unattractive people, but does not indicate whether it is an advantage to be attractive or a disadvantage to be unattractive. Two studies investigated the direction of attractiveness stereotyping by comparing judgments of positive and negative attributes for medium vs. low and medium vs. high attractive faces. Taken together, results for adults (Experiment 1) and children (Experiment 2) suggest that most often, unattractiveness is a disadvantage, consistent with negativity bias (e.g., Rozin & Royzman, 2001) but contrary to the "beauty-is-good" aphorism. 相似文献

Moving visual stimuli have been shown to reduce unilateral neglect (ULN), however, the mechanisms underlying these effects remain poorly understood. This study compared lateralised and non-lateralised moving visual stimuli to investigate whether the spatial characteristics or general alerting properties of moving visual stimuli are responsible for reducing neglect. Post-stroke left neglect patients as well as healthy and patient control subjects were tested on a computerised line bisection task under six visual stimulus conditions. The key finding was that, relative to the no stimulus condition, leftward moving and left-sided moving visual stimuli shifted neglect patients' bisection errors leftward while the non-lateralised random moving visual stimuli did not reduce neglect patients' rightward bisection errors. The results provide evidence that spatial characteristics rather than general alerting properties of moving visual stimuli reduce rightward bisection errors in ULN. Moreover, the pattern of findings strongly supports the notion that moving visual stimuli reduce neglect by capturing attention and drawing it to a spatial location rather than by activating the attentional system via superior collicular neurons. 相似文献

Fulfilling intimate relationships require a constant emotional and psychological struggle to disentangle strangleholds created by the interpenetration of unresolved complexes stemming from previous disappointing relational experiences. These complexes may manifest as an encrypted pattern of engagement that each partner brings to the marriage, like a 'malignant dowry'. The dowry box, once opened, releases its nefarious contents to create an extremely complex and entangled drama I call the 'interlocking traumatic scene'. Partners unconsciously entrap each other to play a part in such a scene with double (sometimes multiple) roles for each antagonist. The imaginal space between the two characters can be seen as a projection screen, upon which are superimposed two separate shadow plays, one on each side of the screen. A third play, which is a co-created product of these two individual traumatic scenes, can also be observed. Three plays are performed simultaneously. The defensive systems that the two individuals bring to the equation dovetail together, but the actual interlocking mechanism itself deadlocks in such a way that it seems to have its own malignant presence, a 'malevolent third' (after Ogden 1994). I outline therapeutic interventions using the metaphor of the therapist as 'anti-director' and I introduce my concept of the conjoint selected fact (after Bion 1963 after Poincaré 1952). 相似文献

The use of structural equation modeling in cross-cultural personality research has become a popular method for testing measurement invariance. In this report, we present an example of testing measurement invariance using the Sense of Coherence Scale of Antonovsky (1993) in 3 ethnic groups: Chinese, Japanese, and Whites. In a series of increasingly restrictive constraints on the measurement models of the 3 groups, we demonstrate how to assess differences among the groups. We also provide an example of construct validation. 相似文献

Suicide is the leading cause of premature death among individuals experiencing psychosis. The risk of suicide is proposed to increase with a greater potential for activation of suicide related schemas. Empirical representations of suicide schemas were compared between individuals experiencing non-affective psychosis, with and without a history of suicidal behaviour. Employing a cross-sectional between-groups comparison design, 84 participants, previously diagnosed with a non-affective psychotic disorder, were recruited from community mental health services. Participants completed a demographic questionnaire and clinical measures of psychopathology. To assess participants’ suicide schemas, a series of direct and indirect cognitive tasks were designed and administered. Pathfinder analysis enabled the construction of empirically derived representations of the groups’ suicide schemas based on responses to the cognitive tasks. The suicide group achieved significantly greater scores on measures of anxiety, depression, hopelessness and suicidality than the non-suicide group, but not on measures indicative of the severity of psychosis. The suicide schema for the suicide group was more elaborate and extensive than for the non-suicide group, even when clinical measures were taken into account. Clinical and theoretical implications are discussed. 相似文献

In §155 of his New Theory of Vision Berkeley explains that a hypothetical ‘unbodied spirit’ ‘cannot comprehend the manner wherein geometers describe a right line or circle’.1The reason for this, Berkeley continues, is that ‘the rule and compass with their use being things of which it is impossible he should have any notion.’ This reference to geometrical tools has led virtually all commentators to conclude that at least one reason why the unbodied spirit cannot have knowledge of plane geometry is because it cannot manipulate a ruler or a compass. In this article I will show that such an interpretation is flawed. I will instead argue that Berkeley's understanding of Euclidian geometry was based on Isaac Barrow's account of the foundations of geometry. On this view geometrical objects are conceived in terms of the idealized motion that generates the objects of geometry. Consequently, that what the unbodied spirit cannot do in this context is to form an idea of motion rather than being unable to handle geometrical tools. 相似文献
