The controversy surrounding B. Rind, P. Tromovitch, and R. Bauserman (1998) provides valuable lessons into scientific independence, politics, and organizational decision making. In an unprecedented action, the U.S. Congress officially condemned findings of Rind et al. Meanwhile, the American Psychological Association took similarly unprecedented measures in an effort to assuage its Congressional critics. This article, written from the perspective of a psychologist serving in Congress, discusses the various political and organizational dynamics that developed during the controversy. Understanding and learning from this incident can help psychologists and their professional associations better prepare for and respond to potential controversies arising from research or other publications. 相似文献

The human channel capacity for identifying sensory stimuli is compared with channel capacities based on neurophysiological findings. Studies have shown that cells in the postsubiculum (PoS) and the anterior dorsal thalamus (ADN) of the rat discharge as a function of the animal's head direction in the horizontal plane. We compute the statistical properties of the firing rates of head direction (HD) cells and the potential amount of information transmitted by these cells according to two theoretical models. The ceU response model for single cells indicates that information transmitted is much less than 0.5 bits. The population response model developed for cell ensembles generates values in the range of 1-3.2 bits, suggesting that a cell population can distinguish between two and nine head directions, depending on the value used for the standard deviation of directions over which a cell fires. These values are similar to those found in human psychophysical studies of the channel capacity for unidimensional sensory attributes. 相似文献

Discerning intentions in dynamic human action 总被引:1,自引:0,他引:1
When we observe others in motion, we usually care little about the surface behaviors they exhibit. What matters are their underlying intentions. Judgments about intentions and intentionality dictate how we understand and remember others' actions, how we respond, and what we predict about their future action. A generative knowledge system underlies our skill at discerning intentions, enabling us to comprehend intentions even when action is novel and unfolds in complex ways over time. Recent work spanning many disciplines illuminates some of the processes involved in intention detection. We review these developments and articulate a set of questions cutting across current theoretical dividing lines. 相似文献

This review addresses how The Palgrave Handbook of Gender and Healthcare structures and analyzes the themes that emerge from its own interrogation of the complex concepts of gender, equality, health and policy. Overall the review takes a complimentary tone towards the handbook's arguments and premises and the unique research that sets it apart from other more scientifically or development based gender health texts. It points out, however, that the book maintains its focus on the global north and the efficacy of state policy as the primary tool for gender equality, however defined. The author suggests that in future discussions, the alternative routes and different countries that are only just touched on in the text should be more thoroughly explored. 相似文献

A common method of studying cross-situational variation in personality involves asking people to describe their behavior in several different contexts. Although this approach is intuitively appealing, it introduces a great deal of redundancy into the measurement process and may affect the interpretation of contextualized self-reports. Specifically, when participants are asked the same questions repeatedly in a single questionnaire, they may be compelled to focus on how their behavior is different. We tested this hypothesis by experimentally manipulating the number of contexts that were included in a measure of role-related personality. In 2 experiments (Study 1 N=377, Study 2 N=524), we found that multiple-role questionnaires produced greater variation in trait levels across roles, larger differences between general and role-specific ratings, and weaker correlations between general and role-specific ratings than single-role questionnaires. These findings illustrate how the measurement process can have an effect on the variability of responses to contextualized self-reports. 相似文献

The relationship between the size of a familiar object and the distances at which it is imaged is examined in three experiments. The distance at which an imaged object overflows the visual field is linearly related to object size, a result consistent with the size-distance invariance hypothesis (Kosslyn, 1980). The distance at which an object is initially imaged, first-sight distance, is related to the object size by a power function with an exponent less than 1. In addition, time required to scan from the first-sight to the overflow distance increases as a function of the difference between the two distance estimates. The distance at which an imaged object becomes too small to be identified, vanishing point distance, is related to object size by a power function with an exponent less than 1. This result does not support predictions made from the size-distance invariance hypothesis or Kosslyn's model of visual imagery. Implications for a theory of visual imagery and memory are discussed. 相似文献

ABSTRACT The present study aimed to replicate the finding that younger age predicts higher pre quit-day attrition. Our second aim was to explain this relation by examining empirically and theoretically informed age-related risk factors for low smoking cessation treatment engagement. 136 participants (M age = 44.2 years, SD = 11.3 years; age = 22–64 years) were randomized to 15-weeks of either 1) an exercise intervention (n = 72) or 2) a wellness education control condition (n = 64). First, a logistic regression analysis was employed to test whether younger adults were more likely than older adults to drop prior to quit date. Next, we assessed whether smoking related health concerns, social expectancies, and/or perceived severity of craving affected the strength of the relation between age and attrition, by adding these three variables to the logistic regression along with age. The logistic regression model indicated that younger age and treatment condition were significantly related to the odds of dropping from treatment prior to the scheduled quit date. Further, health concerns, social expectancies, and/or perceived severity of cravings did not account for the effect of age on pre quit-day attrition. These findings highlight the importance of identifying empirically and theoretically informed variables associated with the pre quit-day attrition problem of young smokers. 相似文献

This study examined the productivity of faculty members who published in nine leading literacy professional journals from 1972–2012. Those universities with the greatest number of articles written by literacy faculty members are listed. This listing was also adjusted according to number of literacy faculty members at each institution, resulting in a productivity index that shows the average number of articles published per faculty member. Results from this study extend the work of four previous studies on institutional productivity in literacy journals. 相似文献
