In the present study, 4 variables (realistic threats, symbolic threats, intergroup anxiety, and negative stereotypes) were used to predict prejudice toward immigrants from Cuba, Mexico, and Asia in samples of students from states in the United States that are affected by immigration from these areas (Florida, New Mexico, and Hawaii, respectively). All 4 variables were significant (or marginally significant) predictors of attitudes toward these immigrant groups. Evidence is presented that the predictor variables are conceptually and empirically distinct. However, these variables do appear to be tied together by an underlying theme: They all concern threats to the in-group or its members. Some of the implications of the results for intergroup relations are discussed.  相似文献

Summary S-R compatibility and Simon effects were studied for real visual motion. In Experiment 1, two small stimulus lights were constantly visible, 5° to the left and right of fixation; after a random delay, one began to move at 2°/s. In Experiment 2, a single stimulus light moving at 2°/s suddenly appeared 5° to the left or right of fixation, i. e., motion onset and stimulus onset coincided. In both experiments, subjects responded by a key press with their left or right index finger as soon as they detected motion. In Condition A responses were made to the position (left or right) from which the motion started, irrespective of its direction (position compatibility); in Condition B responses were made to the direction of motion (leftward or rightward) irrespective of whether motion started to the left or to the right of fixation (direction compatibility). The results show strong compatibility effects for both position and direction of motion in both experiments. A Simon effect, however, occurred only when position was task irrelevant in Experiment 1; no Simon effect was found in Experiment 2. The data only partly confirm previous results obtained with apparent motion. The selective lack of a Simon effect supports the integrated model of Umiltá and Nicoletti (1992), which requires orienting of attention for the Simon effect to occur. It is specifically assumed that this attention-orienting is triggered only by the saccade program and does not extend to the pursuit program that is initiated by smooth stimulus motion.  相似文献

A very powerful, but inexpensive, advanced technology (16 MHz 80C188EB) experiment controller is described. It can be programmed in either a BASIC-like (ECBASIC) or an ALGOL-like (ECL) procedure specification language. It provides 1-msec resolution, optional transparent total data logging, and is designed to function as a remote peripheral processor in a network with virtually any computer acting as the network supervisor (e.g., IBM compatible or Macintosh). Each serial port on the host computer can support up to 10 simultaneous experiments. The various optional I/O modules provide for opto-isolated normally open or normally closed switch operation input, high current output, as well as D/A and A/D functions. Our I/O modules can also be plugged directly into an IBM PC parallel port by using a small adaptor board. In this way, the advantages of using ECBASIC or ECL to control experiments are available to researchers who wish to simply interface their host computer directly to the apparatus in order to minimize expense.  相似文献

Abstract :  Ted Peters' framework for ecumenic engagement provides elements that will advance such an encounter with Islam. Applying several of Peters' terms to interreligious relationships, Walter Wagner looks at various meetings between Muhammad and Christians contemporary to him. He cites the contacts between Muhammad and the first Muslim communities with Christians (610–632 AD) as both negative and positive paradigms for subsequent relationships. Wagner then points to Surah 1 as the key Quranic text for understanding Islam in relationship to Christianity. Reflecting on past efforts at dialogue and predicting what will be important future issues, Wagner stresses the intense religious nature of Islamic political‐social expectations and projects three factors for future ecumenic encounters between Islam and Christianity.  相似文献

Evidence exists that there is low agreement between multiple informants reporting on children's and adolescents' behavior problems. Few studies, however, focus on agreement between informants in specific age groups. This study examined correspondence and disagreement between mother, father, and teacher reports of problem behavior by analyzing CBCL and TRF data of 2 nonclinical samples of 5- to 6-year-old preschool children (N = 424). Findings indicated that interrater agreement was low to moderate. This was shown by the intercorrelations, the explained variance in regression analyses and the little overlap in the number of children rated as behaviorally disturbed by all 3 informants. Agreement between mother and father reports was highest, whereas agreement between mother and teacher reports was lowest. Disagreement between informants was highest for internalizing problems. Potential explanations for the lack of agreement are discussed. Guidelines are formulated to refine assessment and optimize clinical decision-making processes.  相似文献

Prospective memory performance can be enhanced by task importance, for example by promising a reward. Typically, this comes at costs in the ongoing task. However, previous research has suggested that social importance (e.g., providing a social motive) can enhance prospective memory performance without additional monitoring costs in activity-based and time-based tasks. The aim of the present study was to investigate the influence of social importance in an event-based task. We compared four conditions: social importance, promising a reward, both social importance and promising a reward, and standard prospective memory instructions (control condition). The results showed enhanced prospective memory performance for all importance conditions compared to the control condition. Although ongoing task performance was slowed in all conditions with a prospective memory task when compared to a baseline condition with no prospective memory task, additional costs occurred only when both the social importance and reward were present simultaneously. Alone, neither social importance nor promising a reward produced an additional slowing when compared to the cost in the standard (control) condition. Thus, social importance and reward can enhance event-based prospective memory at no additional cost.  相似文献

Abstract

In this article, I deal with the concept of truth and lie in Jewish traditional literature, examining its development in the Hebrew Bible and rabbinic literature. An essential aspect in understanding this concept is the dualism of ‘good’ and ‘evil’ impulses and the free will of human beings, who were created in the image of God and have the choice to decide between right and wrong.  相似文献

Background: Anxiety disorders pose serious public health problems. The data available on anxiety disorders in the transgender population is limited by the small numbers, the lack of a matched controlled population and the selection of a nonhomogenous group of transgender people.

Aims: The aims of the study were (1) to determine anxiety symptomatology (based on the HADS) in a nontreated transgender population and to compare it to a general population sample matched by age and gender; (2) to investigate the predictive role of specific variables, including experienced gender, self-esteem, victimization, social support, interpersonal functioning, and cross-sex hormone use regarding levels of anxiety symptomatology; and (3) to investigate differences in anxiety symptomatology between transgender people on cross-sex hormone treatment and not on hormone treatment.

Methods: A total of 913 individuals who self-identified as transgender attending a transgender health service during a 3-year period agreed to participate. For the first aim of the study, 592 transgender people not on treatment were matched by age and gender, with 3,816 people from the general population. For the second and third aim, the whole transgender population was included.

Measurements: Sociodemographic variables and measures of depression and anxiety (HADS), self-esteem (RSE), victimization (ETS), social support (MSPSS), and interpersonal functioning (IIP-32).

Results: Compared with the general population transgender people had a nearly threefold increased risk of probable anxiety disorder (all p < .05). Low self-esteem and interpersonal functioning were found to be significant predictors of anxiety symptoms. Trans women on treatment with cross-sex hormones were found to have lower levels of anxiety disorder symptomatology.

Conclusions: Transgender people (particularly trans males) have higher levels of anxiety symptoms suggestive of possible anxiety disorders compared to the general population. The findings that self-esteem, interpersonal functioning, and hormone treatment are associated with lower levels of anxiety symptoms indicate the need for clinical interventions targeting self-esteem and interpersonal difficulties and highlight the importance of quick access to transgender health services.  相似文献
