This essay analyzes Senator Bill Frist's 2001 address to the American Society of Thoracic Surgeons. The author argues that the address represents an attempt to reframe physicians' political identity to authorize more active participation by them. Frist authorizes and demands such participation through the construction of a medical jeremiad. He argues that American physicians must have greater involvement to preserve the health of the body politic and to reassert physician control over the biomedical system. Although Frist's arguments are built on an apparently democratic form of address, his jeremiad illustrates aristocratic possibilities in medico-political rhetoric. 相似文献

The perirhinal cortex was once thought to be "silent cortex", virtually ignored by researchers interested in the neurobiology of learning and memory. Following studies of brain damage associated with cases of amnesia, perirhinal cortex is now widely regarded as part of a "medial temporal lobe (MTL) memory system". This system is thought to be more or less functionally homogeneous, having a special role in declarative memory, and making little or no contribution to other functions such as perception. In the present article, we summarize an alternative view. First, we propose that components of the putative MTL system such as the hippocampus and perirhinal cortex have distinct and dissociable functions. Second, we provide evidence that the perirhinal cortex has a role in visual discrimination. In addition, we propose a specific role for perirhinal cortex in visual discrimination: the contribution of complex conjunctive representations to the solution of visual discrimination problems with a high degree of "feature ambiguity". These proposals constitute a new view of perirhinal cortex function, one that does not assume strict modularity of function in the occipito-temporal visual stream, but replaces this idea with the notion of a hierarchical representational continuum. 相似文献

Two personality models are compared regarding their relationship with personality disorder (PD) symptom counts and with lifetime Axis I diagnoses. These models share 5 similar domains, and the Big 7 model also includes 2 domains assessing self-evaluation: positive and negative valence. The Big 7 model accounted for more variance in PDs than the 5-factor model, primarily because of the association of negative valence with most PDs. Although low-positive valence was associated with most Axis I diagnoses, the 5-factor model generally accounted for more variance in Axis I diagnoses than the Big 7 model. Some predicted associations between self-evaluation and psychopathology were not found, and unanticipated associations emerged. These findings are discussed regarding the utility of evaluative terms in clinical assessment. 相似文献

Memory for the final location of a moving target is often displaced in the direction of target motion, and this has been referred
to asrepresentational momentum. Characteristics of the target (e.g., velocity, size, direction, and identity), display (e.g., target format, retention interval,
and response method), context (landmarks, expectations, and attribution of motion source), and observer (e.g., allocation
of attention, eye movements, and psychopathology) that influence the direction and magnitude of displacement are reviewed.
Specific conclusions regarding numerous variables that influence displacement (e.g., presence of landmarks or surrounding
context), as well as broad-based conclusions regarding displacement in general (e.g., displacement does not reflect objective
physical principles, may reflect aspects of naive physics, does not solely reflect eye movements, may involve some modular
processing, and reflects high-level processes) are drawn. A possible computational theory of displacement is suggested in
which displacement (1) helps bridge the gap between perception and action and (2) plays a critical part in localizing stimuli
in the environment. 相似文献

We examined the potentially mediating effects of negative affectivity (NA) on the hope–depression relationship among a sample
of postpartum women. We also assessed the social support reported by these women and examined the possible mediating effects
of NA on the social support–postpartum depression relationship. Correlational analyses of data obtained from women (N = 98) who had given birth in the previous 6 months revealed that NA did not mediate either hope or social support in the
prediction of postpartum depression. Hope accounted for a significant degree of variance in postpartum depression. These data
suggest that hope has palliative effects among women following childbirth and these effects are not nullified or explained
by emotional predispositions. 相似文献

Contrasting linguistic and nonlinguistic processing has been of interest to many researchers with different scientific, theoretical,
or clinical questions. However, previous work on this type of comparative analysis and experimentation has been limited. In
particular, little is known about the differences and similarities between the perceptual, cognitive, and neural processing
of nonverbal environmental sounds and that of speech sounds. With the aim of contrasting verbal and nonverbal processing in
the auditory modality, we developed a new on-line measure that can be administered to subjects from different clinical, neurological,
or sociocultural groups. This is an on-line task of sound to picture matching, in which the sounds are either environmental
sounds or their linguistic equivalents and which is controlled for potential task and item confounds across the two sound
types. Here, we describe the design and development of our measure and report norming data for healthy subjects from two different
adult age groups: younger adults (18–24 years of age) and older adults (54–78 years of age). We also outline other populations
to which the test has been or is being administered. In addition to the results reported here, the test can be useful to other
researchers who are interested in systematically contrasting verbal and nonverbal auditory processing in other populations. 相似文献

Two diary studies investigated the prevalence of memory conjunction errors for real-life events. In both studies, participants completed detailed diary pages over the course of several weeks. Participants in both diary studies committed memory conjunction errors on a later recognition memory test. In the second diary study participants also made remember/know judgements. For a large proportion of their memory conjunction errors participants indicated that they "remembered" the event occurring in that context. These diary studies demonstrate that memory conjunction errors do occur for autobiographical memories, and these errors can seem compelling. 相似文献

The latent structure, reliability, and validity of the Behavioral Inhibition/Behavioral Activation Scales (BIS/BAS; C. L. Carver and T. L. White, 1994) were examined in a large sample of outpatients (N = 1,825) with anxiety and mood disorders. Four subsamples were used for exploratory and confirmatory factor analyses. In addition to generally upholding a latent structure found previously in nonclinical samples, results indicated measurement invariance of the BIS/BAS between genders and a higher order structure of the BAS scales. Convergent and discriminant validity of the BIS/BAS were supported by findings that the subscales correlated most strongly with measures of neighboring personality constructs (e.g., BIS with neuroticism, BAS with positive affect) than with measures of current anxiety and depression symptoms. Overall, the results support the psychometric properties of the BIS/BAS in this clinical sample. 相似文献
