Object-substitution masking (OSM) is a unique paradigm for the examination of object updating processes. However, existing models of OSM are underspecified with respect to the impact of object updating on the quality of target representations. Using two paradigms of OSM combined with a mixture model analysis we examine the impact of post-perceptual processes on a target’s representational quality within conscious awareness. We conclude that object updating processes responsible for OSM cause degradation in the precision of object representations. These findings contribute to a growing body of research advocating for the application of mixture model analysis to the study of how cognitive processes impact the quality (i.e., precision) of object representations. 相似文献
The World Health Organization indicates depression is the leading cause of disability worldwide. At the same time researchers have found religion/spirituality is inversely associated with depression. However, the mechanisms by which spirituality/religion impacts mental health have not been clearly identified particularly in non-western populations. Relational spirituality is a concept that focuses attention on the ways people relate to the sacred. This study examines whether different ways of relating to the sacred are implicated in levels of depression and whether marital partners affect each other’s level of relational spirituality and depression. Ninety-one (n?=?91) married heterosexual couples in the Caribbean Island of Antigua completed measures of relational spirituality and depression. Data were analysed using path analysis and through Actor Partner Interdependence Model methods. Results of the analysis showed wives’ and husbands’ depression scores covaried (COV?=?6.59, Pearson r?=?.28, p?.05). Three dimensions of relational spirituality predicted wives increased depression low disappointment scores (β?=??.24, unstandardised B?=??3.23, se?=?1.30), and higher instability scores (β?=?.49, unstandardised B?=?5.46, se?=?.96). The husbands’ disappointment (β?=?.21, unstandardised B?=?2.17, se?=?.95) and instability (β?=?.54, unstandardised B?=?4.65, se?=?.72) were positively related to their depression scores. The results demonstrate relational spirituality is a useful framework for addressing depression in individuals as well as married couples. 相似文献
The problems of racism and racially motivated violence in predominantly African American communities in the United States are complex, multifactorial, and historically rooted. While these problems are also deeply morally troubling, bioethicists have not contributed substantially to addressing them. Concern for justice has been one of the core commitments of bioethics. For this and other reasons, bioethicists should contribute to addressing these problems. We consider how bioethicists can offer meaningful contributions to the public discourse, research, teaching, training, policy development, and academic scholarship in response to the alarming and persistent patterns of racism and implicit biases associated with it. To make any useful contribution, bioethicists will require preparation and should expect to play a significant role through collaborative action with others. 相似文献
Young Black gay/bisexual men (YBGBM) are affected by contextual stressors—namely syndemic conditions and minority stress—that threaten their health and well‐being. Resilience is a process through which YBGBM achieve positive psychosocial outcomes in the face of adverse conditions. Self‐efficacy, hardiness and adaptive coping, and social support may be important resilience factors for YBGBM. This study explores different profiles of these resilience factors in 228 YBGBM in New York City and compares profiles on psychological distress, mental health, and other psychosocial factors. Four profiles of resilience were identified: (a) Low self‐efficacy and hardiness/adaptive coping (23.5%); (b) Low peer and parental support (21.2%); (c) High peer support, low father support (34.5%); and (d) High father and mother support, self‐efficacy, and hardiness/adaptive coping (20.8%). YBGBM in profile 1 scored markedly higher on distress (d =.74) and lower on mental health functioning (d =.93) compared to men in the other profiles. Results suggest that self‐efficacy and hardiness/adaptive coping may play a more important role in protecting YBGBM from risks compared to social support and should be targeted in interventions. The findings show that resilience is a multidimensional construct and support the notion that there are different patterns of resilience among YBGBM. 相似文献
Objective: Sleep disturbance in chronic pain is common, occurring in two-thirds of patients. There is a complex relationship between chronic pain and sleep; pain can disrupt sleep and poor sleep can exaggerate pain intensity. This may have an impact on both depressive symptoms and attention to pain. This study aims to evaluate the relationship between chronic pain and sleep, and the role of mood and attention.
Methods: Chronic pain patients, recruited from a secondary care outpatient clinic, completed self-report measures of pain, sleep, depressive symptoms and attention to pain. Hierarchical regression and structural equation modelling were used to explore the relationships between these measures. Participants (n = 221) were aged between 20 and 84 (mean = 52) years.
Results: The majority of participants were found to be ‘poor sleepers’ (86%) with increased pain severity, depressive symptoms and attention to pain. Both analytical approaches indicated that sleep disturbance is indirectly associated with increased pain severity Instead the relationship shared by sleep disturbance and pain severity was further associated with depressive symptoms and attention to pain.
Conclusions: Our results indicate that sleep disturbance may contribute to clinical pain severity indirectly though changes in mood and attention. Prospective studies exploring lagged associations between these constructs could have critical information relevant to the treatment of chronic pain. 相似文献
The phenomenon of absent fathers is a common occurrence in today's homes that appears to be escalating, especially in Black households across the United States. The purpose of this study was to describe the lived experiences of successful Black men who were raised in absent‐father homes as well as the lived experiences of their resilient single mothers. The authors share themes that captured the participants' experiences and provide recommendations for community counselors, school counselors, and counselor educators. El fenómeno de padres ausentes es una situación común en los hogares actuales que parece estar en crecimiento, especialmente en hogares de familias negras en Estados Unidos. El propósito de este estudio era describir las experiencias vividas por hombres negros exitosos que fueron educados en hogares con padres ausentes, además de las experiencias vividas por sus resilientes madres solteras. Los autores comparten temas que capturaron las experiencias de los participantes y proporcionan recomendaciones para consejeros comunitarios, consejeros en escuelas y capacitadores de consejeros. 相似文献
