This study examined the effect of anticipated food deprivation on intake in restrained and unrestrained eaters. Participants were randomly assigned to a diet condition, in which they expected to diet for a week, or to a control (no-diet) condition. Immediately after being assigned to a condition, participants completed a taste-rating task in which food consumption was measured. Restrained eaters in the diet condition consumed significantly more food than did restrained eaters in the no-diet condition or unrestrained eaters in either condition. Unrestrained eaters consumed the same amount regardless of condition. These results confirm that merely planning to go on a diet can trigger overeating in restrained eaters, reflecting the dynamic connection between dieting and overeating. 相似文献

Accessibility of characters in two-character sentences (e.g., The butler helped Calvin at the wedding reception) was investigated with a probe recognition task. Probes were either the first character (e.g., butler) or the second character (e.g., Calvin) in a sentence and were designated by proper names or common nouns crossed with name or noun nonprobes. Results show that (1) probes in first position are more accessible than those in second position, but not when noun probes are paired with name nonprobes, (2) characters designated by names are generally more accessible than those designated by nouns, and (3) the first name in a sentence is more available than other characters, regardless of position. Thus, accessibility of characters in a sentence seems dependent on discourse function, with named characters seen as main characters, rather than on nondiscourse-related factors, such as temporal distinctiveness. 相似文献

Do Positive Self-Perceptions Have a “Dark Side”? Examination of the Link between Perceptual Bias and Aggression 总被引:5,自引:0,他引:5
The hypothesis that positive self-perceptions may have a dark side was investigated in the present study by examining the relationship between positively biased self-perceptions and aggression. Ratings of actual and perceived social acceptance of third-grade (n = 278), fourth-grade (n = 260), and fifth-grade (n = 321) students were compared to form a measure of perceptual bias. Peers provided nominations for overt and relational aggression. Gender differences were found for aggression (males were more overtly and relationally aggressive than females) but not perceptual bias. African-American children held more positive perceptions of their social acceptance and were perceived by peers as more aggressive than Caucasian children. Even after controlling for the effects of gender and ethnicity, more positively biased perceptions were associated with more peer nominations for overt and relational aggression. Contrary to an optimal range of bias hypothesis, even moderately positive self-perceptions were associated with elevated levels of aggression. 相似文献

This paper examines the role of word frequency in the computation of subject–verb number agreement. Previous research in both production and comprehension has demonstrated that processing difficulties can arise in sentence structures containing a singular subject noun followed by a plural distractor noun, as in The key to the cabinets.¨ A whole sentence reading task was employed to determine whether the relative frequency with which the distractor noun appears in its singular or plural form would affect the degree of processing difficulty experienced by readers. Results suggest that the agreement process is, indeed, sensitive to this factor and this finding is compatible with activation-based accounts of the implementation of number agreement. 相似文献

Thomas Wolfe was an American novelist who in his short and tragic life (1900-1939) was preoccupied with themes of lost youth, memory, transience and an insatiable wandering. Wolfe was preoccupied with what I have seen, felt and thought. He was a wanderer who in his brief life made seven voyages to Europe and compulsively explored that continent. He would never own a home or a piece of land. He rarely lived in an apartment for more than a year and more commonly for just a few months. The purpose of this paper is to explore the meaning of Wolfe's tormented wandering and his endless searching. It will be my thesis that Wolfe demonstrated an inability to mourn. His writings are an attempt to recapture his past and to restore a lost world. Emphasis will be placed on themes of loss and mourning, insatiable hunger and desire, preoccupation with transience and death, and a search for that which was lost. 相似文献

The Ponzo illusion affects grip-force but not grip-aperture scaling during prehension movements 总被引:10,自引:0,他引:10
Jackson SR Shaw A 《Journal of experimental psychology. Human perception and performance》2000,26(1):418-423
Contextual cues such as linear perspective and relative size can exert a powerful effect on the perception of objects. This fact is demonstrated by the illusory effects that can be induced by such cues (e.g., the Ponzo railway track and Titchener circles illusions). Several recent studies have reported, however, that visual illusions based on such cues have little or no influence on the visuomotor mechanisms used to guide hand action. Furthermore, evidence of this sort has been cited in support of a distinction between visual perception and the visual control of action. In the current study, the authors investigated the effect of the Ponzo visual illusion on the control of hand action, specifically, the scaling of grip force and grip aperture during prehension movements. The results demonstrate that grip force scaling is significantly influenced by the Ponzo visual illusion, whereas the scaling of grip aperture is unaffected by the illusion. 相似文献

Research on the hopelessness and self-esteem theories of depression (Abramson, Metalsky, & Alloy, 1989; Metalsky, Joiner, Hardin, & Abramson, 1993) suggests that HIV-infected persons with depressotypic attributional style (AS) and low self-esteem (SE) may be at risk for onset of a syndrome referred to as hopelessness depression (HD). In a prospective study conducted to test these theories, measures of anxiety and depression, AS, and SE were administered to 85 HIV+ and 43 HIV– men; symptoms were reassessed 6 months later. Results indicated that: (1) The interaction of AS, SE, and HIV status predicted change in HD symptoms, but not overall depression or anxiety symptoms; (2) HIV+ men with depressotypic AS and high SE had increased HD symptom levels while other men with high SE had decreased HD symptom levels; (3) HD symptoms remained stable over the 6-month interval among men with low SE; and (4) High SE predicted decreases in anxiety symptoms among HIV– men, but not among HIV+ men. Contrary to the study hypothesis, these findings suggest that among individuals with life-threatening illnesses such as HIV infection, those with depressotypic AS and high SE may be at highest risk for onset of HD. 相似文献

Advances in genomic research are increasingly identifying genetic components in major health and mental health disorders. This article presents a Family System Genetic Illness model to address the psychosocial challenges of genomic conditions for patients and their families, and to help organize this complex biopsychosocial landscape for clinical practice and research. This model clusters genomic disorders based on key characteristics that define types of disorders with similar patterns of psychosocial demands over time. Key disease variables include the likelihood of developing a disorder based on specific genetic mutations, overall clinical severity, timing of clinical onset in the life cycle, and whether effective treatment interventions exist to alter disease onset and/or progression. For disorders in which carrier, predictive, or presymptomatic testing is available, core nonsymptomatic time phases with salient developmental challenges are described pre- and post-testing, including a long-term adaptation phase. The FSGI model builds on Rolland's Family System Illness model, which identifies psychosocial types and phases of chronic disorders after clinical onset. The FSGI model is designed to be flexible and responsive to future discoveries in genomic research. Its utility is discussed for research, preventive screening, family assessment, treatment planning, and service delivery in a wide range of healthcare settings. 相似文献

Role of the inertial eigenvectors in proprioception near the limits of arm adduction range of motion 总被引:1,自引:0,他引:1
Common everyday activities such as reaching for a cup, combing one's hair, or positioning a tool involve the accurate registration of the limb's orientation relative to the body and the environment. Past work has demonstrated that the ability of humans to perceive the spatial orientation of an occluded arm is tied to the arm's inertial eigenvectors, invariant mechanical parameters corresponding to a limb's axes of rotational symmetry. In a recent study participants pointed to visible targets while the arms' inertial eigenvectors were displaced by asymmetrically weighted splints. The lack of an effect of those splints on pointing error led them to conclude that inertial eigenvectors are not the primary invariants used for proprioception. However, their data suggested an effect of the eigenvectors, but only for conditions in which pointing did not require placing the arm near the limits of shoulder adduction range of motion. In the present study we found a significant effect of displacing the eigenvector for all tested arm angles, regardless of degree of shoulder adduction. Overall, the results supported the hypothesis that proprioception is based on sensitivity to the limb's inertial eigenvectors, with no reduction of the eigenvector effect when adducting the arm so as to reach far across the body midline. 相似文献

Male and female university students from the United States, Canada, Germany, the Netherlands, Ecuador, Pakistan, the Philippines, Taiwan, and Turkey read a standardized scenario in which a male professor was accused of sexually harassing a female graduate student. Respondents from individualist countries judged the professor to be guilty of sexual harassment more often than did those from collectivist countries. Women rendered significantly more guilty judgments and assigned more severe punishments to the accused professor than did men. Implications for the individualist–collectivist classification system and cross-cultural research are discussed. 相似文献
