This study presents data on the norms and psychometric properties of the Beck Anxiety Inventory (BAI), using a sample of 225 community adult volunteers. Maximum-likelihood confirmatory factor analyses of previously published models of the BAI: a two-factor model and a five-factor model, showed that the fit of each model was unacceptable. Also, the fit of the single-factor model was poor. Exploratory principal-components analyses with varimax and oblique rotations suggested four BAI components within this sample. Satisfactory levels of reliability were established for the BAI subscales. Finally, the relations between the BAI total and subscale scores and a related measure of anxiety and with another self-report measure of psychological distress were examined.This paper was presented at the 27th Annual Convention of the Association for Advancement of Behavior Therapy, Atlanta, Georgia, November 1993. 相似文献
Recent lines of research have begun to concentrate on internal dialogue and its relationship to a diversity of psychopathological phenomena present in psychotic disorders. This study was intended as a preliminary exploration of the relationship of internal dialogue, dissociation and ideas of reference. To do this, a sample of 318 students filled in an internal dialogue scale (the VISQ, McCarthy‐Jones & Fernyhough), one for dissociation (DES‐II, Carlson & Putnam) and another for ideas of reference (REF, Lenzenweger, Bennett & Lilenfeld). The results confirm the hypothesis posed in the sense that internal dialogue was positively associated with dissociation and with ideas of reference. A partial mediation effect of dissociation was also found between inner speech and ideas of reference. Lines of future research this study opens and its possible integration in a model on ideas of reference are discussed. 相似文献
Background: Transgender and gender nonconforming (TGNC) individuals encounter a variety of minority stressors that have yet to be fully articulated or explored within the research literature. The purpose of this study is to better understand internalized stigma—the experience of accepting and internalizing negative social messages and experiences about one's identity—an underexplored minority stressor for TGNC people.
Method: We conducted in-depth interviews with 30 diverse TGNC participants using consensual qualitative research (CQR) methodology.
Results: Following data saturation and analysis, six distinct themes emerged across participants: (1) TGNC identities are regarded negatively by society; (2) social messages are perceived as originating from the media and religious ideology; (3) TGNC individuals report emotional distress; (4) negative self-perceptions in response to social messages; (5) TGNC individuals report resilience processes in response to negative social messages; and (6) social messages are perceived generally to differentially impact TGNC people of color.
Conclusion: Findings highlight the common experience of encountering social marginalization for TGNC individuals. Structural interventions that target pervasive sociocultural messages regarding TGNC identities are warranted. 相似文献
This article describes the design and preliminary evaluation of a small-sized and low energy consumption wearable wireless
telemetry system for the recording of extracellular neuronal activity, with the possibility of selecting one of four channels.
The system comprises four radio frequency (RF) transceivers, three microcontrollers, and a digital amplifier and filter. This
constitutes an innovative distributed processing approach. Gain, cutoff frequencies, and channel selection are remotely adjusted.
Digital data transmission is used for both the bioelectrical signals and the control commands. This feature offers superior
immunity to external RF interference. Real-time viewing of the acquired data allows the researcher to select only relevant
data for storage. Simultaneous recordings of neuronal activity from the striatum of a freely moving rat, both with the wireless
device and with a wired data acquisition system, are shown. 相似文献
We conducted preference assessments with 4 typically developing children to identify potential reinforcers and assessed the reinforcing efficacy of those stimuli. Next, we tested two predictions of economic theory: that overall consumption (reinforcers obtained) would decrease as the unit price (response requirement per reinforcer) increased and that the cost and benefit components that defined unit price would not influence overall consumption considerably when unit price values were equal. We tested these predictions by arranging unit price such that the denominator was one (e.g., two responses produced one reinforcer) or two (e.g., four responses produced two reinforcers). Results showed that consumption decreased as unit price increased and that unit price values with different components produced similar consumption. 相似文献
For over four decades the Wisconsin Card Sorting Test (WCST) has been one of the most distinctive tests of prefrontal function. Clinical research and recent brain imaging have brought into question the validity and specificity of this test as a marker of frontal dysfunction. Clinical studies with neurological patients have confirmed that, in its traditional form, the WCST fails to discriminate between frontal and non-frontal lesions. In addition, functional brain imaging studies show rapid and widespread activation across frontal and non-frontal brain regions during WCST performance. These studies suggest that the concept of an anatomically pure test of prefrontal function is not only empirically unattainable, but also theoretically inaccurate. The aim of the present review is to examine the causes of these criticisms and to resolve them by incorporating new methodological and conceptual advances in order to improve the construct validity of WCST scores and their relationship to prefrontal executive functions. We conclude that these objectives can be achieved by drawing on theory-guided experimental design, and on precise spatial and temporal sampling of brain activity, and then exemplify this using an integrative model of prefrontal function [i.e., Miller, E. K. (2000). The prefrontal cortex and cognitive control. Nature Reviews Neuroscience, 1, 59–65.] combined with the formal information theoretical approach to cognitive control [Koechlin, E., & Summerfield, C. (2007). An information theoretical approach to prefrontal executive function. Trends in Cognitive Sciences, 11, 229–235.]. 相似文献
Several studies have indicated that dyslexics show a deficit in speech perception (SP). The main purpose of this research is to determine the development of SP in dyslexics and normal readers paired by grades from 2nd to 6th grade of primary school and to know whether the phonetic contrasts that are relevant for SP change during development, taking into account the individual differences. The achievement of both groups was compared in the phonetic tasks: voicing contrast, place of articulation contrast and manner of articulation contrast. The results showed that the dyslexic performed poorer than the normal readers in SP. In place of articulation contrast, the developmental pattern is similar in both groups but not in voicing and manner of articulation. Manner of articulation has more influence on SP, and its development is higher than the other contrast tasks in both groups. 相似文献
