Motion perception involves the processing of velocity signals through several hierarchical stages of the visual cortex. To better understand this process, a number of studies have sought to localise the neural substrates of two misperceptions of motion direction, the direction illusion (DI) and the direction aftereffect (DAE). These studies have produced contradictory evidence as to the hierarchical order of the processing stages from which the respective phenomena arise. We have used a simple stimulus configuration to further investigate the sequential order of processes giving rise to the DI and DAE. To this end, we measured the two phenomena invoked in combination, and also manually parsed this combined effect into its two constituents by measuring the two phenomena individually in both possible sequential orders. Comparing the predictions made from each order to the outcome from the combined effect allowed us to test the tenability of two models: the DAE-first model and the DI-first model. Our results indicate that DAE-invoking activity does not occur earlier in the motion processing hierarchy than DI-invoking activity. Although the DI-first model is not inconsistent with our data, the possible involvement of non-sequential processing may be better able to reconcile these results with those of previous studies. 相似文献

We examined associations between spiritual well-being and CAM use among 4,139 cancer survivors. We also explored the classification
of religious/spiritual practices (R/S) as CAMs and alternative subscale structures of the Functional Assessment of Chronic
Illness Therapy—Spiritual Well-being (FACIT-Sp). We evaluated three aspects of spirituality, Faith, Peace, and Meaning, and
use of 19 CAMs in 5 domains. Mind–body methods were subdivided into R/S and non-R/S. All FACIT-Sp factors were associated
with CAM use, but in different directions: Meaning and Faith were positively associated; Peace was negatively associated.
Peace was negatively associated with R/S CAMs, but not non-R/S CAMs. The prevalence of CAM use dropped from 79.3 to 64.8%
when R/S items were excluded. These findings confirm an association between spiritual well-being and CAM use, including some
non-R/S CAMs, and provide evidence of the benefits of using the three-factor FACIT-Sp solution and treating R/S CAMs as a
separate category. 相似文献

The Craftsman and His Apprentice: A Kohutian Interpretation of the Gospel Narratives of Jesus Christ
Kohutian theory suggests that relationships play a central role in structuring and sustaining the psychological self. In this
article, we apply self psychology to the Father-Son dyad found in the Synoptic and Johannine narratives in order to understand
the Jesus of the gospels in a new, psychologically informed manner. Conclusions are drawn related to how self psychology can
help to elucidate the biblical relationship between God the Father and Son, or the craftsman and his apprentice, as well as
how, conversely, the Father-Son dyad described in the gospels can inform self psychology. 相似文献

Policies and programs designed to challenge the effects of racial discrimination (such as affirmative action) are hotly contested. Factors which have been proposed to explain opposition to these policies include racial prejudice, group threat and self‐interest, and perceptions of intergroup justice. We report the results of two random national telephone surveys which tested a theoretically based model of the predictors of policy support in post‐apartheid South Africa. The results provided limited support for Blumer's group position model. Compensatory and preferential treatment policies had different underlying predictors: Violated entitlement featured in the models of compensatory policy attitudes, but not preferential treatment policy attitudes, where threat was the strongest predictor. In addition to threat and violated entitlement, policy attitudes among the black sample were related to ingroup identification but those of the white sample were related to prejudice. The effects of these variables were in the opposite directions for the two samples: Policy support was associated with strong ingroup identification and high levels of threat among the black sample (i.e. prospective beneficiaries of the transformation policies), but with low levels of prejudice and threat among the white sample. We conclude by considering the implications that these findings have for social change programs. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

The literature suggests that in sensory imagination we focus on the imagined objects, not on the imaginative states themselves,
and that therefore imagination is not introspective. It is claimed that the introspection of imaginative states is an additional
cognitive ability. However, there seem to be counterexamples to this claim. In many cases in which we sensorily imagine a
certain object in front of us, we are aware that this object is not really where we imagine it to be. So it looks as if in
these cases of imagination, we are aware of the mere appearance of the imagined object, and hence introspection is a constitutive
part of imagination. In this article, I address this contradictory state of affairs and argue that we should classify at least
some forms of sensory imagination as introspective. For this purpose I use the appearance-reality distinction as a central
notion for introspection. I also defend the thesis of introspective imagination against the objection that young children
imagine without yet understanding the concept of experience. 相似文献

W. V. O. Quine’s assault on the analytic/synthetic distinction is one of the most celebrated events in the history of twentieth
century philosophy. This paper shines a light on Quine’s own understanding of the history of this distinction. More specifically,
this paper argues, contrary to what seems to be the received view, that Quine explicitly recognized a kindred subversive spirit
in David Hume. 相似文献

In the face of prejudice against an ingroup, common ground for communication exists when people use similar social categories to understand the situation. Three studies tested the hypothesis that describing perceptions of prejudice can fundamentally change those perceptions because communicators account for the common ground in line with conversational norms. When women (Study 1), African Americans (Study 2), and Americans (Study 3) simply thought about suspected prejudice against their ingroup, categorization guided their perceptions: Participants assimilated their views of the prejudiced event toward the perceptions of ingroup members but contrasted away from the perceptions of outgroup members. Conversely, when participants described their perceptions, they contrasted away from the given category information and actually arrived at the opposite perceptions as those who merely thought about the prejudiced event. Study 3 identified an important qualification of these effects by showing that they were obtained only when participants could assume their audience was familiar with the common ground. Implications are discussed for understanding the role of communication in facilitating and inhibiting collective action about prejudice. 相似文献

To examine if animals could learn action-like categorizations in a manner similar to noun-based categories, eight pigeons were trained to categorize rates of object motion. Testing 40 different objects in a go/no-go discrimination, pigeons were first trained to discriminate between fast and slow rates of object rotation around their central y-axis. They easily learned this velocity discrimination and transferred it to novel objects and rates. This discrimination also transferred to novel types of motions including the other two axes of rotation and two new translations around the display. Comparable tests with rapid and slow changes in the objects' size, color, and shape failed to support comparable transfer. This difference in discrimination transfer between motion-based and property-based changes suggests the pigeons had learned motion concept rather than one based on change per se. The results provide evidence that pigeons can acquire an understanding of motion-based actions, at least with regard to the property of object velocity. This may be similar to our use of verbs and adverbs to categorize different classes of behavior or motion (e.g., walking, jogging, or running slow vs. fast). 相似文献

Based on their "drugs as instruments" framework, Müller & Schumann (M&S) propose a staged drug policy that matches well the neoliberal governance scheme. To mend the sad loss of the sociocultural dimension in their model, I propose three such considerations: first, sociocultural interactions with the brain; second, sociocultural context and justice of drug use; and third, sociocultural preparedness for implementing their drug policy. 相似文献
