An informal theory is set forth of relations between abstract entities, includingcolors, physical quantities, times, andplaces in space, and the concrete things thathave them, or areat orin them, based on the assumption that there are close analogies between these relations and relations between abstractsets and the concrete things that aremembers of them. It is suggested that even standard scientific usage of these abstractions presupposes principles that are analogous to postulates of abstraction, identity, and other fundamental principles of set theory. Also discussed is the significance of important disanalogies between sets and physical abstractions, including especiallymodal andtemporal aspects of physical abstractions, which is related to the problem of the characterizingconstancy, of colors, physical attributes, and locations in space. 相似文献

This study describes the development and validation of the Homophobia Scale. The scale was developed to assess the cognitive, affective, and behavioral components of homophobia. The participants (n=321 for the field trials and n=122 for test–retest reliability) were college students from a large Midwestern university. Results yielded a 25-item questionnaire consisting of three factors: a factor that assesses mainly negative cognitions regarding homosexuality, a factor that assess primarily negative affect and avoidance of homosexual individuals, and a factor that assesses negative affect and aggression toward homosexual individuals. Concurrent validity was established using The Index of Homophobia (Hudson & Ricketts, 1980). The phases of scale development and implications of the results are discussed. 相似文献

Self-identified sexually aggressive (SA) and nonaggressive (NA) college men listened to audiotape analogues of consensual sexual intercourse and acquaintance rape. Phallometric and decision-latency methodology was used to examine sexual arousal and decisions to stop sexual advances in each scenario. Both groups showed increases in penile response to the consensual scenario. Consistent with the inhibition model of sexual aggression, the SA group showed greater sexual arousal and failed to inhibit responding when force was introduced in the rape, whereas the NA group exhibited less arousal and greater inhibition to force. The SA group allowed the rape to continue significantly longer than the NA group. These effects were greatly magnified in SA men who endorsed high calloused sexual beliefs, implying that a cognitive set that justifies sexual aggression and lacks victim empathy may disinhibit sexual arousal and potentiate coercive decision making. 相似文献

Allocentric spatial memory was studied in dogs of varying ages and sources using a landmark discrimination task. The primary goal of this study was to develop a protocol to test landmark discrimination learning in the dog. Using a modified version of a landmark test developed for use in monkeys, we successfully trained dogs to make a spatial discrimination on the basis of the position of a visual landmark relative to two identical discriminanda. Task performance decreased, however, as the distance between the landmark and the “discriminandum” was increased. A subgroup of these dogs was also tested on a delayed nonmatching to position spatial memory task (DNMP), which relies on egocentric spatial cues. These findings suggest that dogs can acquire both allocentric and egocentric spatial tasks. These data provide a useful tool for evaluating the ability of canines to use allocentric cues in spatial learning. 相似文献

In this article we respond to van Hoof's (1999) critique of the identity status paradigm. Our review and evaluation of the existing data on identity statuses lead us to be more optimistic than van Hoof about the convergent and discriminant validity of identity status measures, especially objective measures that provide continuous status scores as well as nominal status classifications. Our review of longitudinal studies revealed that among university students tested annually 3 or more times, change in status classifications is significantly more likely to be observed than stability. Moreover, virtually all longitudinal studies with university students indicate that status changes are more likely to be progressive rather than regressive in terms of the hypothesized identity status developmental sequence. However, considerable status regression and fluctuation is observed and we agree with van Hoof that it may no longer be useful to postulate an invariant sequence of identity status stages. Nonetheless, the data do indicate reliable status differences in self-regulatory control processes including ego development, social-cognitive processing orientations, cognitive complexity, self-integration, moral development, and so on. Consequently, we conclude that a useful strategy, at least with university students, may be to focus on the social-cognitive processes that underpin identity statuses and to conceptualize these identity orientations as different styles of dealing with the demands, challenges, and opportunities afforded by institutionalized moratoria, such as a university context. Two lines of recent research inspired by this conceptualization are discussed. 相似文献

Mean body mass indices (BMIs, kg/m2)of North Americans aged 18 to 24 collected from 11national health surveys were compared to: Playboycenterfold models, Miss America Pageant winners,andPlaygirl models. The survey samples were representative of themix of different ethnic and racial groups in Canada andthe USA. No racial or ethnic information was availablefor either the Playboy women or the Miss America Pageant winners. Ninety percent of the Playgirlmen were white; 10%, black; 1.5%, Hispanic black; and.8%, American Samoan. From the 1950s to the present,while the body sizes of Miss America Pageant winners decreased significantly and the body sizes ofPlayboy centerfold models remained below normal bodyweight, the body sizes of Playgirl models and youngadult North American women and men increasedsignificantly. The increase in body size of Playgirl modelsappears to be due to an increase in muscularity, whereasthe increase in body size of young North American menand women is more likely due to an increase in body fat. Thus, in the 1990s, the body size andshape of the average young adult North American becameincreasingly different from the ideal being promoted bythe media. Furthermore the difference in male and female body sizes depicted by the media inthe 1990s was huge, whereas the difference between thebody sizes of 18- to 24-year-old North American womenand men was actually quite small. These discrepancies are discussed in relation to the differentsociocultural expectations for the two genders and theincreasing prevalence of body dissatisfaction reportedby both women and men. 相似文献

The purpose of this study was to evaluate the effectiveness of a traditional weight control program and nondiet alternative in improving behavioral (e.g., restrained, emotional, and external eating), psychological (e.g., body preoccupation, physical self-esteem), and biomedical (e.g., body weight, blood pressure, cholesterol) outcomes. There were 2 intervention groups--traditional weight control (TWC) and Diet Free Forever (DFF); a nonvolunteer comparison group; and a control group, all made up of employees of 3M (N = 357). The 2 intervention groups participated in 10-week eating programs. Outcome variables were assessed at baseline, at 10 weeks for the intervention groups only, and again at 1 year. At baseline, the 2 intervention groups had higher restrained, external, and emotional eating scores, greater body preoccupation, and lower physical self-esteem than the comparison and control groups. They also weighed more. At 1 year, both intervention groups had decreased their body preoccupation and increased their physical self-esteem. Participants in the DFF program reduced their restrained eating, whereas those in the TWC program increased their restrained eating. Neither eating program had an impact on the biomedical outcomes. 相似文献

The purpose of this investigation was to determine if the speech of “successfully therapeutized” stutterers and a group of partially treated stutterers was perceptually different from the speech of normal speakers when judged by unsophisticated listeners. Tape-recorded speech samples of treated stutterers were obtained from leading proponents of (1) Van Riperian, (2) metronome-conditioned speech retraining, (3) delayed auditory feedback, (4) operant conditioning, (5) precision fluency shaping, and (6) “holistic” therapy programs. Fluent speech samples from these groups of stutterers were paired with matched fluent samples of normal talkers and presented to a group of 20 unsophisticated judges. The judges were instructed to select from each paired speech sample presented to them the one produced by the stuttering subject. The results of the analyses showed that five of seven experimental groups were identified at levels significantly above chance. It can be concluded that the fluent speech of the partially and successfully treated stutterers was perceptibly different from the utterances of the normal speakers and that the perceptual disparity can be detected, even by unsophisticated listeners. 相似文献
