Responses to speeded judgment (e.g., “shoot/don’t shoot”) situations in naturalistic environments are influenced by many variables and psychological processes. We describe a custom-built simulator with head- and eye-tracking capabilities for basic and applied research on speeded decision making. The system allows the user to project life-sized, time-coded, videotaped, or computer-animated scenarios on a screen to collect reaction-time, shot-accuracy, and eye-movement data. An initial experiment is also reported to demonstrate the utility of the system for studying factors that affect speeded judgment under naturalistic situations. 相似文献

This ethnography research attempts to detect the male perception and behavior on sexual and gender relations in a small and
simple life style fishing village on the south Atlantic Coast of Brazil. The fieldwork lasted six months and consists of personal
participant observation and long personal interviews with 41 men ranging in terms of sexual orientation from 0 to 6 according
to Kinsey’s scale. In summary, perceptions and behaviors in this “simple society” are very atypical in relation to professional
middle class in urban area of southeast of Brazil. In this society even many “straight” men customarily have sex with local
“gay” men. The local “gay” men, called “paneleiros”, present a homosexual behavior typical to other societies. In comparison
to other cross-cultural research the outcome of this case study suggests that it is possible to have at least three different
categories of male sexuality: men who have sex only with other men, men who have sex only with women, and men who have sex
with men and women; In addition it brings more concrete evidence to the current literature that suggests some kind of universal
homosexual identity at least for people who are close to 6 in Kinsey’s scale.

This study falls within the theoretical framework of the construct of the Efficient Personality. In this work, we present the study of validity and reliability of an original questionnaire made up of 60 items, applied to students from formative cycles of higher Professional Training. The questionnaire was reduced to 24 items, surpassing its initial .84 Cronbach alpha coefficient. Six first-order factors were obtained: Social Self-concept, Academic Self-concept, Solving Ability, Self-esteem, and Problem Coping. One second-order factor was obtained: Efficient Personality. The six-component factorial solution is similar both to the Spanish version for secondary school and to the Chilean versions for secondary and university populations, dividing the initial dimension of Self-concept into Self-concept and Self-esteem. 相似文献

This paper explores the relative helpfulness of counselling/psychotherapy to individuals experiencing specific learning difficulties, as a means of reducing barriers to learning by allowing the individual to return to learning from experience. Highlighting earlier studies which indicate the positive impact of psychological therapy on educational attainment and inhibiting factors such as stress, this research investigates the experience of counselling from the perspective of the person with specific learning disabilities. Using Empirical Phenomenological Research, the study explores their understandings of the circumstances and factors by which therapy is found to be helpful or unhelpful, seeking to contribute to debate on whether psychological interventions that are ‘specialist’ in orientation are potentially more helpful than ‘generalist’ therapeutic approaches. The findings point both to the potential value of psychological therapies for persons with special educational needs as a complement to other interventions and also to the importance of considering the experiences of the client in addition to diagnostic assessments. 相似文献

The social perception of risk is considered a multidimensional task, yet little attention has been paid to the cognitive components that organize sources of risk, despite their having been discovered in various research studies. This study attempts to concretely analyze the cultural dimension involved in those processes. In the first phase, we tried to discover to what extent sources of risk are organized into the same categories by people from different countries. In order to do so, two groups of participants were formed: 60 Spanish psychology students and 60 Chilean psychology students classified 43 sources of risk into different groups according to the criteria they found appropriate. The two samples classified risk into identical groups: acts of violence, drugs, electricity and home appliances, household chemicals, chemicals in the environment, public construction projects, transportation, sports, and natural disasters. In a second study, 100 Spanish and 84 Chilean students were asked to evaluate the magnitude of the damage incurred by 17 sources of risk. In both groups, it was observed that the evaluation of damage resulting from each source of risk was affected by its category. 相似文献

Previous studies on tool using have shown that presenting subjects with certain modifications in the experimental setup can substantially improve their performance. However, procedural modifications (e.g. trap table task) may not only remove task constraints but also simplify the problem conceptually. The goal of this study was to design a variation of the trap-table that was functionally equivalent to the trap-tube task. In this new task, the subjects had to decide where to insert the tool and in which direction the reward should be pushed. We also administered a trap-tube task that allowed animals to push or rake the reward with the tool to compare the subjects' performance on both tasks. We used a larger sample of subjects than in previous studies and from all the four species of great apes (Gorilla gorilla, Pan troglodytes, Pan paniscus, and Pongo pygmaeus). The results showed that apes performed better in the trap-platform task than in the trap-tube task. Subjects solved the tube task faster than in previous studies and they also preferred to rake in rather than to push the reward out. There was no correlation in the level of performance between both tasks, and no indication of interspecies differences. These data are consistent with the idea that apes may possess some specific causal knowledge of traps but may lack the ability to establish analogical relations between functional equivalent tasks. 相似文献

The current article attempts to extend previous research by testing the effects of customer satisfaction and 2 types of switching barriers—negative and positive—on key manifestations of attitudinal loyalty (repurchase intentions, positive recommendations, and price tolerance). The work also studies whether the effect of customer satisfaction is linear or nonlinear. Finally, the paper analyzes whether switching barriers moderate the relative strength of the customer satisfaction/attitudinal loyalty relation. To this end, a total of 554 private mobile‐phone customers were surveyed. The distinction between negative and positive switching barriers is important to draw theoretical and managerial implications. 相似文献

The effect of repetitive stress during acute infection with Trypanosoma cruzi (T. cruzi) on the chronic phase of ensuing Chagas' disease was the focus of this investigation. The aim of this study was to evaluate in Wistar rats the influence of repetitive stress during the acute phase of infection (7 days) with the Y strain of T. cruzi on the chronic phase of the infection (at 180 days). Exposure to ether vapor for 1 min twice a day was used as a stressor. Repetitive stress enhanced the number of circulating parasites and cardiac tissue disorganization, from a moderate to a severe diffuse mononuclear inflammatory process and the presence of amastigote burden in the cardiac fibers. Immunological parameters revealed that repetitive stress triggered a reduced concanavalin A induced splenocyte proliferation in vitro with major effects on the late chronic phase. Serum interleukin-12 concentration decreased in both stressed and infected rats in the early phase of infection although it was higher on 180 days post-infection. These results suggest that repetitive stress can markedly impair the host's immune system and enhance the pathological process during the chronic phase of Chagas' disease. 相似文献

People have a folk theory of social change (FTSC). A typical Western FTSC stipulates that as a society becomes more industrialized, it undergoes a natural course of social change, in which a communal society marked by communal relationships becomes a qualitatively different, agentic society where market‐based exchange relationships prevail. People use this folk theory to predict a society's future and estimate its past, to understand contemporary cross‐cultural differences, and to make decisions about social policies. Nonetheless, the FTSC is not particularly consistent with the existing cross‐cultural research on industrialization and cultural differences, and needs to be examined carefully. 相似文献

This article describes the design and preliminary evaluation of a small-sized and low energy consumption wearable wireless
telemetry system for the recording of extracellular neuronal activity, with the possibility of selecting one of four channels.
The system comprises four radio frequency (RF) transceivers, three microcontrollers, and a digital amplifier and filter. This
constitutes an innovative distributed processing approach. Gain, cutoff frequencies, and channel selection are remotely adjusted.
Digital data transmission is used for both the bioelectrical signals and the control commands. This feature offers superior
immunity to external RF interference. Real-time viewing of the acquired data allows the researcher to select only relevant
data for storage. Simultaneous recordings of neuronal activity from the striatum of a freely moving rat, both with the wireless
device and with a wired data acquisition system, are shown. 相似文献
