The present study investigated the effect of haloperidol-induced mood in normal healthy male volunteers on the retrieval of memories of real-life personal experiences using a between-subjects double-blind design. Forty subjects were required to retrieve past real life experiences associated with a series of stimulus words following administration of a single oral dose of 5mg haloperidol or placebo. The experiences were subsequently rated by subjects for their happiness felt at the time of the original experience. A significant decline in self-reported hedonic tone was observed in subjects given haloperidol. In addition, subjects on placebo recalled a significantly greater percentage of happy memories than subjects who were on haloperidol; a trend for a reverse pattern was observed for unhappy memories. The effects of the drug on the retrieval of memories were only in part mediated by the decline in hedonic tone scores. The effects of haloperidol are interpreted in terms of drug-induced dysphoria. 相似文献

An Evaluation of the Cross-Cultural Validity of Holland's Theory: Career Choices by Workers in India
Frederick T.L. Leong James T. Austin Uma Sekaran Meera Komarraju 《Journal of Vocational Behavior》1998,52(3):441-455
The current study evaluated the cross-cultural validity of Holland's (1985) theory through internal and external analyses based on the responses of 172 natives of India who completed the Vocational Preference Inventory (VPI) and measures of job and occupational satisfaction. Internal consistency estimates for Holland dimensions, intercorrelations among participants' vocational interest scales, and the results of a randomization test (Tracey, 1997) all provide evidence for the internal structure of the VPI with Indians. However, the VPI did not exhibit high external validity. Further, multiple regression results indicated that congruence, consistency, and differentiation did not predict job or occupational satisfaction, suggesting cross-cultural boundaries on Holland's theory itself. Finally, we assessed and found limited conceptual and linguistic equivalence of measurement of the VPI in India. The assumptions of Holland's theory in light of the current findings are discussed. 相似文献

The biomedicalist conceptualization of disablement as a personal medical tragedy has been criticized by disability studies scholars for discounting the difference between disability and impairment and the ways disability is produced by socio-environmental factors. This paper discusses prospects for partnerships between disability studies teaching/research and medical education; addresses some of the themes around the necessity of critical disability studies training for medical students; and examines a selection of issues and themes that have arisen from disability education courses within medical schools globally. The paper concludes that providing there is a commitment from senior management, universities are well positioned to apply both vertical and horizontal approaches to teaching disability studies to medical students. 相似文献

Several researchers have found that pleasant foreground stimuli attenuate the eyeblink component of the startle reflex while unpleasant foreground stimuli potentiate it. The effects of personality factors on such modulation of the eyeblink response, as measured by electromyographic (EMG) activity in reaction to loud acoustic startle probes, were examined in subjects viewing emotionally-toned (pleasant, unpleasant and neutral) filmclips. During the main part of the experiment, introverts had higher baseline EMG activity and lower response probability than extraverts; no differences were observed at the beginning of the experiment, during an acclimatization session. Reflex modulation, as measured by response latency, was influenced by the Psychoticism (P) factor of the Eysenck Personality Questionnaire: subjects high on P showed longer latencies to eyeblink onset when probed during viewing of pleasant filmclips than subjects low on this dimension; no significant differences were observed between subjects low and high on P for neutral and unpleasant filmclips. No influence of personality factors was found on affective modulation as measured by response amplitude/magnitude. The results are discussed in relation to Gray's and Eysenck's theories of personality. 相似文献

Oxoborates have both dielectric and magnetic properties useful for magnetodielectric devices, sensors, or biological tools. Such compounds Fe2BO4, Fe3BO5, or Fe3BO6 are known to grow easily as single crystals in a liquid flux. A polycrystalline phase forms only on controlled conditions of a solid state reaction of the basic oxides. In this study, we report highly dielectric Fe3BO6 when grown in a specific shape of nanorods (~200?nm diameter and 50–100?µm length) from an iron borate glass, which offers devisable shapes of sheets, discs, and fibers. Frequency (f)-temperature reliant dynamics of dielectric constant εr is studied over 25–300°C at 0.1–103?kHz frequencies. At low frequency such as 100?Hz, a large εr -value 40,000, better than most of high εr -value ferroelectrics, incurs at room temperature. At f?≥?50?kHz, although only an order of diminished εr -value lasts, it increases steadily with temperature, possibly due to increasing electrical conductivity in a specific resistor–capacitor network. Suppressed dielectric relaxation and spin-flops share a merely weak spin-reorientation transition near 160°C. A stable power loss ≤0.5 lasts at f?>?10?kHz useful for possible applications of magnetodielectric materials. 相似文献

Personality and learning styles are both likely to play significant roles in influencing academic achievement. College students (308 undergraduates) completed the Five Factor Inventory and the Inventory of Learning Processes and reported their grade point average. Two of the Big Five traits, conscientiousness and agreeableness, were positively related with all four learning styles (synthesis analysis, methodical study, fact retention, and elaborative processing), whereas neuroticism was negatively related with all four learning styles. In addition, extraversion and openness were positively related with elaborative processing. The Big Five together explained 14% of the variance in grade point average (GPA), and learning styles explained an additional 3%, suggesting that both personality traits and learning styles contribute to academic performance. Further, the relationship between openness and GPA was mediated by reflective learning styles (synthesis-analysis and elaborative processing). These latter results suggest that being intellectually curious fully enhances academic performance when students combine this scholarly interest with thoughtful information processing. Implications of these results are discussed in the context of teaching techniques and curriculum design. 相似文献
