In a number of experiments, blindfolded subjects traced convex curves whose verticals were equal to their horizontal extent at the base. Overestimation of verticals, as compared with horizontals, was found, indicating the presence of a horizontal-vertical illusion with haptic curves, as well as with visible curves. Experiment 1 showed that the illusion occurred with stimuli in the frontal plane and with stimuli that were flat on the table surface in vision and touch. In the second experiment, the stimuli were rotated, and differences between vision and touch were revealed, with a stronger illusion in touch. The haptic horizontal-vertical illusion was virtually eliminated when the stimuli were bimanually touched using free exploration at the body midline, but a strong illusion was obtained when curves were felt with two index fingers or with a single hand at the midline. Bimanual exploration eliminated the illusion for smaller 2.5- through 10.2-cm stimuli, but a weakened illusion remained for the largest 12.7-cm patterns. The illusion was present when the stimuli were bimanually explored in the left and right hemispace. Thus, the benefits of bimanual exploration derived from the use of the two hands at the body midline combined with free exploration, rather than from bimanual free exploration per se. The results indicate the importance of haptic exploration at the body midline, where the body can serve as a familiar reference metric for size judgments. Alternative interpretations of the results are discussed, including the impact of movement-based heuristics as a causal factor for the illusion. It was suggested that tracing the curve’s peak served to bisect the curve in haptics, because of the change in direction.  相似文献

The Mini-Mental State Examination (MMSE) and the Peabody Picture Vocabulary Test-Revised (PPVT-R) were administered to 217 Veterans Affairs (VA) Nursing Home patients, 104 of whom did not carry a diagnosis associated with brain impairment, and 113 who had a diagnosis associated with degenerative or cerebrovascular conditions. MMSE and IQ scores were significantly correlated in both groups, even controlling for the effects of education. It is suggested that although previous normative studies of the MMSE may provide good general clinical guidance, interpretation of “impaired” performance on the MMSE for those with IQ scores below 90 should be approached with caution. Average MMSE scores for Wechsler IQ classifications are provided.  相似文献

During the past decade, historians and social scientists have begun extensively to research the issue of philanthropy and charities in general, and that of Jewish philanthropy in particular. This paper reviews some of the main characteristics of philanthropic activity of the Jewish elite in post-emancipation Europe (1791–1878) and especially in Britain. Elite philanthropy was not the only form of philanthropy in the Jewish community. Middle-class philanthropy was another form, and traditional charitable activities constituted a third form. This paper focuses solely on elite philanthropy in England between c.1850–c.1880. Moses Montefiore and Lionel de Rotshchild were two of the most influential leaders of the Anglo-Jewish philanthropic elite. The paper deals mostly with the activities of these leaders of the Jewish community in mid-nineteenth-century Britain.  相似文献

Students who view intelligence as malleable tend to be more academically motivated and perform at higher levels than students who view it as a fixed trait. We examined the beliefs of students from Malawi because the culture and schooling process in this country is very different from some other areas of the world in which students’ views of intelligence have already been studied. Our research questions were: (1) How do Malawian students define intelligence? (2) To what extent do Malawian students view intelligence as malleable? (3) Are Malawian students’ definitions of intelligence and beliefs about the malleability of intelligence similar to those of students in more developed countries? We conducted a mixed methods study and surveyed 136 students attending a secondary school in Malawi using a 39‐item questionnaire. Students responded to questions about their intelligence beliefs on open‐ and closed‐ended items. Our results showed that Malawian students believe that an intelligent student exhibits a variety of behaviors, including studying, working hard, reading, performing well on exams and in class, answering and asking questions, paying attention, and demonstrating good behavior. Most students believe that intelligence is malleable and provided responses that indicated that students can become more intelligent through effort. When compared to the findings of other studies, the present results suggest that the Malawian students who remain in secondary school have definitions of intelligence and beliefs about the malleability of intelligence that are similar to those of students in more developed countries, such as the US and Germany. In fact, it appears that Malawian secondary students have even higher malleable beliefs than American and German students. Finally, some of the measures that have been found to produce scores that are reliable and valid in other populations do not produce scores that are as reliable when used with Malawian students.  相似文献

Objectives: To investigate the differences in the contributing factors involved in weight maintenance success and failure.

Design: Semi-structured interviews were conducted with both successful and unsuccessful weight maintainers. Eighteen participants were recruited (16 women), nine of who had lost 10% of their body weight and maintained this weight for a minimum of 12?months (Maintainers), and nine individuals who met the above criteria for weight loss but had subsequently regained their weight (Regainers). A thematic analysis was employed to compare the differences between the two groups.

Results and conclusions: Two main themes highlighted the differences between the two groups, these were: goal regulation and self-control. Within these overarching themes, successful weight maintenance was related to the following subthemes: long-term, realistic goal setting, consistent use of routines and self-monitoring, avoiding deprivation and effective coping skills. Unsuccessful maintenance was related to short-term unrealistic goal setting, inconsistent routines and self-monitoring, experiencing deprivation and poor coping skills. These factors are explained in terms of the interrelationships that they have on one another and their subsequent impact on weight maintenance success or failure.  相似文献

Anxiety sensitivity, or the fear of anxiety sensations, has been implicated in the etiology of anxiety disorders, particularly panic disorder. Recently, inconsistent findings have been reported regarding the latent structure of anxiety sensitivity. Whereas some taxometric studies of anxiety sensitivity have reported evidence of categorical latent structure, others have found evidence of a latent dimension. The purpose of the present research was to further examine the latent structure of anxiety sensitivity using taxometric procedures and commonly utilized measures of anxiety sensitivity. To this end, three mathematically independent taxometric procedures (MAXEIG, MAMBAC, and L-Mode) were applied to data collected from two large nonclinical samples (n's = 1,171 and 2,173) that completed the Anxiety Sensitivity Index and the Anxiety Sensitivity Index-Revised. Results from both studies converged in support of a dimensional conceptualization of anxiety sensitivity. A third study was conducted using indicators derived from the newly revised Anxiety Sensitivity Index-3 in a separate sample of 1,462 nonclinical participants. Results of these analyses provided further support for a dimensional anxiety sensitivity solution. The implications of these results for anxiety sensitivity research are discussed, and several potential directions for future research are considered.  相似文献

This study examines variability in patterns of peer group antipathy. Same-grade adolescent peer groups were identified from sociometric nominations of preferred affiliates in a community sample of 600 Finnish ninth-grade middle school students (mean age = 15.0 years). Hierarchical linear modeling determined characteristics of youths in actor groups (nominators) that predicted antipathy for youths in target groups (nominatees) on the basis of target group characteristics. Most antipathies were based on dissimilarity between groups representing the mainstream culture and groups opposed to it. The higher a peer group’s school burnout, the more its members disliked students in peer groups with higher school grades and students in peer groups with higher sports participation. Conversely, the higher a peer group’s school grades, the more its members disliked students in peer groups with higher school burnout. Students in peer groups with less problem behavior disliked students in peer groups with more problem behavior. There was some evidence of rivalry within the mainstream culture: The higher a group’s school grades, the more its members disliked groups whose members participated in sports.  相似文献

The Lothian Birth Cohort 1936 sample is in a uniquely good position to provide relevant data on social class mobility patterns over most of the last century. These participants, with known ultimate social class attainment, took a validated mental test in the Scottish Mental Survey of 1947 and were followed up at approximately age 70. Then, besides their own age 11 mental ability data and educational and occupational attainment, they reported educational and occupational data on their parents and offspring. We constructed structural equation models of participant and offspring social class attainment and odds of social class movement, and compared results with those from the similarly recruited and assessed Lothian Birth Cohort 1921. In the 1936 cohort, relative transmission of social class from one generation to the next decreased, while relative transmission of educational attainment increased. In addition, effects of childhood IQ and educational attainment on social class decreased, apparently due to relative decrease in overall upward mobility and absolute increase in overall education level.  相似文献
