Five male undergraduates could earn 4¢ for every 200 knob-pulls. In addition, they could avoid or terminate an aversive tone by pressing a button with a force of 1.5 lbs (nonaggressive response) or by hitting a cushion with at least 20 lbs force (aggressive response). Rates of aggression tended to be higher during sessions where money was taken from the Ss at the rate of 1¢ per 12 seconds than during sessions when taking was not in effect. Rates of nonaggressive responses were constant across conditions. 相似文献

Atypical speech lateralization in adults with developmental coordination disorder demonstrated using functional transcranial Doppler ultrasound 下载免费PDF全文
Research using clinical populations to explore the relationship between hemispheric speech lateralization and handedness has focused on individuals with speech and language disorders, such as dyslexia or specific language impairment (SLI). Such work reveals atypical patterns of cerebral lateralization and handedness in these groups compared to controls. There are few studies that examine this relationship in people with motor coordination impairments but without speech or reading deficits, which is a surprising omission given the prevalence of theories suggesting a common neural network underlying both functions. We use an emerging imaging technique in cognitive neuroscience; functional transcranial Doppler (fTCD) ultrasound, to assess whether individuals with developmental coordination disorder (DCD) display reduced left‐hemisphere lateralization for speech production compared to control participants. Twelve adult control participants and 12 adults with DCD, but no other developmental/cognitive impairments, performed a word‐generation task whilst undergoing fTCD imaging to establish a hemispheric lateralization index for speech production. All participants also completed an electronic peg‐moving task to determine hand skill. As predicted, the DCD group showed a significantly reduced left lateralization pattern for the speech production task compared to controls. Performance on the motor skill task showed a clear preference for the dominant hand across both groups; however, the DCD group mean movement times were significantly higher for the non‐dominant hand. This is the first study of its kind to assess hand skill and speech lateralization in DCD. The results reveal a reduced leftwards asymmetry for speech and a slower motor performance. This fits alongside previous work showing atypical cerebral lateralization in DCD for other cognitive processes (e.g., executive function and short‐term memory) and thus speaks to debates on theories of the links between motor control and language production. 相似文献

货币·金融危机·新自由主义——关于现代化与当代资本主义的访谈 总被引:1,自引:0,他引:1
The current global financial crisis is essentially a credit crisis of currencies. The divorce of the U.S. dollar from Gold Specie Standard makes its issuance under the control of the U.S. government and even risk losing control. When the U.S. dollar becomes the world currency,the U.S government would be able to influence and even control the central banks of other countries through issuing U.S. dollars. However,it may also lead to the credit crisis if there is no sufficient wealth to establish a solid found... 相似文献

This study examined the effects of implicitly presented odors on the emotional content of memory narratives. Participants were exposed to low levels of perfumes or no odors while they reconstructed a memory from childhood and a recurrent dream. Narratives were analyzed for emotional content using the Linguistic and Inquiry Word Count program. Exposure to perfumes increased the percentage of positive emotion words used by participants in recalling both dreams and childhood memories. In addition, exposure to odors decreased the percentage of negative emotion words that men used in their narratives, whereas the opposite effect was found for women. Discussion focuses on gender differences in written emotional expression, possible ways by which perfumes may exert their effects, and the usefulness of using ambient odors and objective content analysis when studying emotions in memories. 相似文献

This study investigated how hope influences the relationship between discrimination and depressive symptoms. Results from participants' (N = 318) responses suggest that increased levels of hope were directly related to decreased levels of depressive symptoms. However, increased levels of hope were also related to a stronger relationship between discrimination and depressive symptoms. Este estudio investigó cómo la esperanza influye en la relación entre discriminación y síntomas depresivos. Los resultados obtenidos a partir de las respuestas de los participantes (N = 318) sugieren que unos niveles más elevados de esperanza estuvieron directamente relacionados con unos niveles más bajos de síntomas depresivos. Sin embargo, los niveles superiores de esperanza también estuvieron relacionados con una relación más fuerte entre discriminación y síntomas depresivos. 相似文献

In 1912, Henri Poincaré published an argument which apparently shows that the hypothesis of quanta is both necessary and sufficient for the truth of Planck's experimentally corroborated law describing the spectral distribution of radiant energy in a black body. In a recent paper, John Norton has reaffirmed the authority of Poincarés argument, setting it up as a paradigm case in which empirical data can be used to definitively rule out theoretical competitors to a given theoretical hypothesis. My goal is to dispute Norton's claim that there is no theoretical underdetermination problem arising between classical physics and early quantum theory. The strategy I use in defending my view is to adopt a suggestion made by Jarrett Leplin and Larry Laudan on how to assess the relative merits of competing theoretical alternatives, where each alternative has an equal capacity to save the phenomena. In the course of the paper, I distinguish between two branches of classical physics: classical mechanics and classical electromagnetism. The former is claimed by Norton and Poincaré to be determinately ruled out by the black body evidence; and it is the former that I argue is compatible with this evidence. 相似文献

Abel and Annon's (Reducing deviant sexual arousal through satisfaction, Denver, Colo., 1982) suggested combination of 'directed masturbation' and 'satiation' to alter deviant sexual preferences, was applied to 10 nonfamilial child molesters. Post-treatment assessments revealed significant reductions in deviant arousal as was expected, but unfortunately there were also reductions in appropriate arousal although these changes did not achieve statistical significance. The results are discussed in terms of their meaning but it is concluded that empirical support for these clinically popular procedures remains weak. 相似文献
