The phenomena of prismatically induced “visual capture” and adaptation of the hand were compared. In Experiment 1, it was demonstrated that when the subject’s hand was transported for him by the experimenter (passive movement) immediately preceding the measure of visual capture, the magnitude of the immediate shift in felt limb position (visual capture) was enhanced relative to when the subject moved the hand himself (active movement). In Experiment 2, where the dependent measure was adaptation of the prism-exposed hand, the opposite effect was produced by the active/passive manipulation. It appears, then, that different processes operate to produce visual capture and adaptation. It was speculated that visual capture represents an immediate weighting of visual over proprioceptive input as a result of the greater precision of vision and/or the subject’s tendency to direct his attention more heavily to this modality. In contrast, prism adaptation is probably a recalibration of felt limb position in the direction of vision, induced by the presence of a registered discordance between visual and proprioceptive inputs.  相似文献

This paper explores the complex interplay that unfolded between analyst and patient around their respective childlessness and aims to draw attention to the larger societal issues of imperative parenthood and the stigma of childlessness. As the analyst confronted her own internal conflicts about motherhood, children, and procreation as a woman living in a pronatalist society (one that encourages increasing birth-rates), she was treating a lesbian patient with a history of childhood relational trauma and sexual abuse who was undergoing fertility treatments. The patient’s experience with assisted reproductive technologies raised complicated questions and concerns within the analyst regarding their emotional impact on her patient and, more broadly, how they might reflect societal dissociation. Themes of trauma, loss, dissociation, and shifting self-states, which emerged during the fertility treatments and wove their way throughout the analysis, are discussed. In addition, the author describes the nature of the therapeutic action in this case.  相似文献

I want to thank Professor George Psathas, Editor ofHuman Studies, for the opportunity to put together this special issue; the Society for Phenomenology and the Human Sciences for providing the stimulating intellectual setting that called forth these papers; and the contributors, who responded so graciously to my suggestions, requests, and pressures. I also want to thank Erica Cavin and Greg Smith, who provided helpful references, and Christina Papadimitriou and Norman Waksler, who offered suggestions on an earlier draft.  相似文献

Five rats pressed levers for food delivered by a multiple variable interval 1-min variable interval 1-min schedule. In theunpredictable conditions, sessions were 20, 40, 60, 80, or 100 min long, determined randomly at the beginning of each session. In thepredictable conditions, each of these session durations was presented for 15 consecutive sessions. Rate of responding changed systematically within the session even when the end of the session was unpredictable. This implies that prospective factors related to anticipation of the end of the session are not necessary for producing withinsession changes in responding. Within-session patterns of responding were also similar for the predictable and unpredictable conditions. This suggests that prospective factors contributed little to the form of the within-session patterns under the present conditions.  相似文献

Advances in technology and the promise of personalized health care are driving greater use of genome sequencing (GS) for a variety of clinical scenarios. As health systems consider adopting GS, they need to understand the impact of GS on the organization and cost of care. While research has documented a dramatic decrease in the cost of sequencing and interpreting GS, few studies have examined how GS impacts genetic counseling workloads. This study examined the time needed to provide genetic counseling for GS in the context of preconception carrier screening. Genetic counselors prospectively reported on the time spent in the results disclosure process with 107 study participants who were part of the NextGen study. We found that the median time for results disclosure was 64 min (ranged from 5 to 229 min). Preparation work was the most time-consuming activity. Qualitative data from journal entries, debrief interviews with genetic counselors, and detailed case conference notes provided information on factors influencing time for results disclosure and implications for practice. Results suggest that expanded carrier screening could require significant increases in genetic counseling time, unless we are able to generate new resources to reduce preparation work or develop other strategies such as the creation of new models to deliver this type of service.  相似文献

The Movement for Black Lives has brought particular attention to the experience of grief in the lives of African American mothers and its use in their advocacy for social reform. Grief-inspired activism is historically significant in the African American community. By highlighting the historical connections between Mamie Bradley Till and present-day African American mothers’ grief over their deceased children, we will discuss the role of grief and mourning in the lives of African American mothers and the way in which their grief is pivotal in shaping their involvement in social justice movements. Furthermore, we will provide suggestions on how to promote social activism among African American mothers.  相似文献

It is unclear whether individuals searching the Internet for assistance with thoughts of suicide are likely to encounter predominantly helpful or harmful resources. This study investigated websites retrieved by searching Google for information and support for suicidal thoughts. Google searches retrieved a high percentage of irrelevant websites (26%, n = 136). Of the 329 relevant websites retrieved, the majority were suicide preventive (68%); however, a considerable proportion of sites expressed mixed (22%) or neutral (8%) suicide attitudes, and 1% were explicitly pro‐suicide. The results highlight a need for suicide prevention organization websites to be made more easily accessible. In the meantime, clinicians should be aware of appropriate websites to recommend to clients.  相似文献

Objective: To assess the effects of conscious and non-conscious processes for prediction of older adults’ physical activity (PA), we tested a dual-process model that integrated motivational (behavioural intention) and volitional (action planning and coping planning) processes with non-conscious, automatic processes (habit).

Method: Participants (N = 215) comprised community-dwelling older adults (M = 73.8 years). A longitudinal design was adopted to investigate direct and indirect effects of intentions, habit strength (Time 1), and action planning and coping planning (Time 2) on PA behaviour (Time 3). Structural equation modelling was used to evaluate the model.

Results: The model provided a good fit to the data, accounting for 44% of the variance in PA behaviour at Time 3. PA was predicted by intentions, action planning, and habit strength, with action planning mediating the intention-behaviour relationship. An effect of sex was also found where males used fewer planning strategies and engaged in more PA than females.

Conclusions: By investigating an integration of conscious and non-conscious processes, this study provides a novel understanding of older adults’ PA. Interventions aiming to promote PA behaviour of older adults should target the combination of psychological processes.  相似文献
