Linear transformations (shear or scale transformations) of either horizontal or vertical disparity give rise to the percept of slant or inclination. It has been proposed that the percept of slant induced by vertical size disparity, known as Ogle's induced-size effect, and the analogous induced-shear effect, compensate for scale and shear distortions arising from aniseikonia, eccentric viewing, and cyclodisparity. We hypothesised that these linear transformations of vertical disparity are processed more slowly than equivalent transformations of horizontal disparity (horizontal shear and size disparity). We studied the temporal properties of the stereoscopic slant and inclination percepts that arose when subjects viewed stereograms with various combinations of horizontal and vertical size or shear disparities. We found no evidence to support our hypothesis. There were no clear differences in the build-up of percepts of slant or inclination induced by step changes in horizontal size or shear disparity and those induced by step changes in vertical size or shear disparity. Perceived slant and inclination decreased in a similar manner with increasing temporal frequency for modulations of transformations of both horizontal and vertical disparity. Considerable individual differences were found and several subjects experienced slant reversal, particularly with oscillating stimuli. An interesting finding was that perceived slant induced by modulations of dilation disparity was in the direction of the vertical component. This suggests the vertical size disparity mechanism has a higher temporal bandwidth than the horizontal size disparity mechanism. However, conflicting perspective information may play a dominant role in determining the temporal properties of perceived slant and inclination. 相似文献
In this article, we engage with cultural sport psychology (CSP) to explore sexual exploitation in USA Gymnastics. Specifically, using critical reflexivity on the Larry Nassar case, we bring to life how systemic abuse in sport is more than a tragedy. We argue that perpetration of abuse persists in sport spaces largely because athletes train and compete in relations of force that privilege structures and practices to which athletes are subordinate. A return to recenter discussions on the significance of oppression and power in the larger discourse and ethical practice of CSP became imperative with the news of U.S. doctor Larry Nassar’s sexual predation. As tools in our advocacy for the reduction of sport sexism and sexual exploitation and abuse, we offer four ethical commitments to the field as we examine the ways systemic gendered violence and oppressions in sport are perpetrated in systems, decision-making, and every practices. We invite CSP scholars and sport psychology practitioners to interrogate and disrupt systemic intersectional disempowerment and cultures of sexual exploitation. 相似文献
ABSTRACTRurality is a vital component of cultural diversity, making it essential to train future counselors on comprehensive mental health counseling practice with rural populations. In this article, we describe the development of a master’s level course that reflects an integrated approach to providing mental health counseling services in rural communities. First, the pedagogical foundation for the course design and positionality are discussed. Second, the course objectives are outlined, and corresponding teaching methods and creative learning assignments are provided. Last, we discuss the strengths and challenges of the course design and implementation. 相似文献
Due to logistical and financial barriers that keep many distressed couples from seeking psychotherapy, online relationship education is a more accessible alternative. In the decade since a web-based program showed equivalent effectiveness to traditional marriage education (Duncan et al., 2009), several fully online programs have been developed and evaluated. We reviewed nine studies of four different programs that sampled 2,000?+?couples. Specifically, we rated each study’s experimental rigor and compared research designs, theoretical and empirical grounding, average post-intervention and follow-up effect sizes, and differential effectiveness. Across studies, measured outcomes included relational (improved satisfaction, quality, confidence, commitment, communication; reduced conflict and aggression) and individual functioning on various indices of mental and physical health, emotional expression, and quality of life. Finally, we discuss the strengths and limitations of the research evidence, describe the two most evidence-based programs (ePREP and OurRelationship) in some detail and make recommendations for future study of these promising kinds of interventions.
