In his article on The Liabilities of Mobility, asserts that "Consciousness presents us with a stable arena for our actions-the world ..." and argues for this property as providing evolutionary pressure for the evolution of consciousness. In this commentary, I will explore the implications of Merker's ideas for consciousness in artificial agents as well as animals, and also meet some possible objections to his evolutionary pressure claim. 相似文献

The Brief Fear of Negative Evaluation Scale (BFNE; M. R. Leary, 1983a) is often used to assess fear of negative evaluation, the core feature of social anxiety disorder. However, few studies have examined its psychometric properties in large samples of socially anxious patients. Although the BFNE yields a single total score, confirmatory factor analysis indicated a 2-factor solution to be more appropriate, with the 1st factor consisting of all straightforwardly worded items (BFNE-S) and the 2nd of all reverse-scored items (BFNE-R). Support was obtained for the convergent and discriminant validity of the BFNE and BFNE-S, but not the BFNE-R. These results suggest that standard scoring of the BFNE may not be optimal for patients with social anxiety disorder. 相似文献

Social anxiety disorder (SAD) is a common, chronic psychiatric disorder characterized by a persistent fear of social or performance situations in which embarrassment can occur. This disorder typically appears during the mid-adolescent years and is unremitting throughout life if not properly treated. SAD presents as two subtypes: the more common and debilitating generalized form, and the nongeneralized form, which consists predominantly of performance anxiety. The majority of patients with SAD have comorbid mental disorders, including mood, anxiety, and substance abuse. No single development theory has been proposed to account for the origins of SAD, although current understanding of the etiology of SAD posits an interaction between psychological and biological factors. Risk factors include environmental and parenting influences and dysfunctional cognitive and conditioning events in early childhood. The neurobiology of SAD appears to involve neurochemical dysfunction, as evidenced by studies of neuroreceptor imaging, neuroendocrine function, and profiles of response to specific medications. Clinical trials have demonstrated that benzodiazepines and antidepressants are effective in the treatment of SAD. The selective serotonin reuptake inhibitors are emerging as the first-line treatment for SAD, based on their proven safety, tolerability, and efficacy. Goals for ongoing future research include development of approaches to achieve remission, to convert nonresponders and partial responders to full responders, and to prevent relapse and maintain long-term efficacy. This monograph explores the epidemiology, clinical presentation, and differential diagnosis of SAD, with a focus on neural circuitry of social relationships and neurochemical dysfunction. The prevalence, rates of recognition and treatment, patterns of comorbidity, quality-of-life issues, and natural history of SAD are discussed as well as pharmacologic and psychosocial treatment strategies for SAD. 相似文献

The "difference position" holds that clinical research and therapeutic medical practice are sufficiently distinct activities to require different ethical rules and principles. The "similarity position" holds instead that clinical investigators ought to be bound by the same fundamental principles that govern therapeutic medicine--specifically, a duty to provide the optimal therapeutic benefit to each patient or subject. Some defenders of the similarity position defend it because of the overlap between the role of attending physician and the role of investigator in a research trial. This overlap is maximal when the same physician occupies both roles with respect to a particular patient-subject. We address the ethical tensions inherent in that role conflict and argue that the tensions are real but manageable. The difference position provides a sound ethical framework within which to manage those tensions, while the similarity position is unsatisfactory because it seeks to deny the existence of the tensions. 相似文献

Active components of classical working memory are conscious, but traditional theory does not account for this fact. Global Workspace theory suggests that consciousness is needed to recruit unconscious specialized networks that carry out detailed working memory functions. The IDA model provides a fine-grained analysis of this process, specifically of two classical working-memory tasks, verbal rehearsal and the utilization of a visual image. In the process, new light is shed on the interactions between conscious and unconscious aspects of working memory. 相似文献

The incarceration of mentally ill youth is a serious problem not receiving the same attention as in adults. In this study, we examine the prevalence of psychopathology and level of behavioral symptomatology in incarcerated youth versus youth receiving community mental health services or hospitalization. We randomly recruited youth from middle South Carolina served by a local CMHC (n = 60), youth served by the state adolescent inpatient program (n = 50), and youth in the S.C. Dept. of Juvenile Justice facilities from the same region (n = 75). We used the DISC-PC 2.3 to evaluate DSM-III-R diagnoses and the CBCL and YSR to evaluate behavioral symptomatology. On the DISC, incarcerated youth had significantly higher mean number of diagnoses and symptoms than CMHC youth, but lower numbers than hospitalized youth. Level of caseness (at least one diagnosis) was 86% in hospital youth, 72% in incarcerated youth, and 60% in CMHC youth. The groups differed in CBCL mean total T, internalizing T, and externalizing T scores as well as mean YSR internalizing T scores. Our results indicate the comparability in level of psychopathology in incarcerated and community-treated populations of youth, and the need to develop diversionary programs to prevent the entry of such youth into the juvenile justice system. 相似文献

Ecological valence theory (EVT; Palmer & Schloss, Proceedings of the National Academy of Sciences 107:8877–8882, 2010) proposes that color preferences are due to affective responses to color-associated objects: That is, people generally like
colors to the degree that they like the objects associated with those colors. Palmer and Schloss found that the average valence
of objects associated with a color, when weighted by how well the objects matched the color (weighted affective valence estimates:
WAVE) explained 80% of the variation in preference across colors. Here, we replicated and extended Palmer and Schloss’s investigation
to establish whether color–object associations can account for sex differences in color preference and whether the relationship
between associated objects and color preference is equally strong for males and females. We found some degree of sex specificity
to the WAVEs, but the relationship between WAVE and color preference was significantly stronger for males than for females
(74% shared variance for males, 45% for females). Furthermore, analyses identified a significant inverse relationship between
the number of objects associated with a color and preference for the color. Participants generally liked colors associated
with few objects and disliked colors associated with many objects. For the sample overall and for females alone, this association
was not significantly weaker than the association of the WAVE and preference. The success of the WAVE at capturing color preference
was partly due to the relationship between the number of associated objects and color preference. The findings identify constraints
of EVT in its current form, but they also provide general support for the link between color preference and color–object associations. 相似文献
