The brightness of pairs of photic pulses, differing in pulse duration and pulse separation. was measured. The data were in general agreement with the neurophysiological model of Bishop and Clare. Pulse duration appeared to have little systematic influence on the shape of the curves. Time between onset of the first and second pulse appeared to be a prime factor determining the receptivity of the cortex to the second pulse. The two pulses were seen as single below about .03 sec separation. The second pulse was always judged brighter than the first.  相似文献

The subjects in these experiments were 132 children, varying in age from 4 to 7 years. These experiments were designed to assess the efficacy of various multiple scheduling procedures in producing reliable stimulus control. The schedules studied were multiple fixed-ratio-extinction (mult FR EXT); multiple differential-reinforcement-of-other-behavior-fixed-ratio (mult DRO FR); multiple differential-reinforcement-for-low-rate-fixed-ratio (mult DRL FR); and multiple fixed-interval-fixed-ratio (mult FI FR). In addition other techniques were investigated, such as presenting FR's in blocks; increasing the size of the FR's; attaching a DRL to the FI members; temporarily shifting to new schedules; and adding an external clock to the FI's. These experiments yielded the following results.1.) Strong stimulus control was produced by mult FR EXT, mult DRO FR, and mult DRL FR schedules. Control for mult FR EXT was mediated principally by the individual stimuli, though on occasion it was dependent in part on the change of stimuli. The mult DRO FR was found to be highly useful for those children who had very high initial rates or who were generally uncooperative and unmanageable.2.) Contrary to a previous finding, some subjects were brought under stimulus control by means of mult FI FR schedules without the aid of additional procedures. Most, however, were not. Additional techniques found to augment the development of mult FI FR control included: (1) presenting FR's in blocks; (2) increasing the size of the FR's; (3) attaching a DRL to the FI component for a time and later removing it; and (4) shifting to a mult DRL FR, developing control, and then returning to the original mult FI FR.3.) Addition of an external clock to the FI components of the mult FI FR had several effects. Strongest control, including well-developed acceleratory patterns during the FI's, was developed in those subjects who had first been shifted from a regular mult FI FR to a mult FR EXT, brought under control, and then returned to the mult FI FR with the clock added. The added clock also produced strong control if it was present when the subject was first begun on a mult FI FR schedule. In some cases, the addition of the clock produced control in subjects who had not been controlled previously by the regular mult FI FR, but these were always subjects who had high rates. The addition of the clock first lowered the rate, then produced control.  相似文献

Each of the major engineering societies has its own code of ethics. Seven “common core” clauses and several code-specific clauses can be identified. The paper articulates objections to and rationales for two clauses that raise controversy: do engineers have a duty (a) to provide pro bono services and/or speak out on major issues, and (b) to associate only with reputable individuals and organizations? This latter “association clause” can be justified by the “proclamative principle,” an alternative to Kant’s universalizability requirement. At the heart of engineering codes of ethics, and implicit in what it is to be a moral agent, the “proclamative principle” asserts that one’s life should proclaim one’s moral stances (one’s values, principles, perceptions, etc.). More specifically, it directs engineers to strive to insure that their actions, thoughts, and relationships be fit to offer to their communities as part of the body of moral precedents for how to be an engineer. Understanding codes of ethics as reflections of this principle casts light both on how to apply the codes and on the distinction between private and professional morality.  相似文献

Several personality models are known for being replicable across cultures, such as the Five‐Factor Model (FFM) or Eysenck's Psychoticism–Extraversion–Neuroticism (PEN) model, and are for this reason considered universal. The aim of the current study was to evaluate the cross‐cultural replicability of the recently revised Alternative FFM (AFFM). A total of 15 048 participants from 23 cultures completed the Zuckerman–Kuhlman–Aluja Personality Questionnaire (ZKA‐PQ) aimed at assessing personality according to this revised AFFM. Internal consistencies, gender differences and correlations with age were similar across cultures for all five factors and facet scales. The AFFM structure was very similar across samples and can be considered as highly replicable with total congruence coefficients ranging from .94 to .99. Measurement invariance across cultures was assessed using multi‐group confirmatory factor analyses, and each higher‐order personality factor did reach configural and metric invariance. Scalar invariance was never reached, which implies that culture‐specific norms should be considered. The underlying structure of the ZKA‐PQ replicates well across cultures, suggesting that this questionnaire can be used in a large diversity of cultures and that the AFFM might be as universal as the FFM or the PEN model. This suggests that more research is needed to identify and define an integrative framework underlying these personality models.

This investigation tested whether social norms and endorsement of humanitarian values interact to influence authoritarians' attitudes toward immigrants. Oyamot, Borgida, and Fisher (2006) found correlational evidence for a model in which: (1) clear social norms for attitudes toward an outgroup (favorable or unfavorable) influence the authoritarianism–attitude relationship in the direction of the norm, and (2) in the absence of clear social norms, endorsement of humanitarian–egalitarian values attenuate the intolerant tendencies of authoritarians. The current investigation tested the model in a survey experiment conducted in a diverse adult sample (N = 388). We measured participants' levels of authoritarian predisposition and endorsement of humanitarian values. Participants were then randomly told that Americans in general had either negative, positive, or mixed opinions about immigrants and immigration (social norm condition), and then asked about their attitude toward immigrants. Consistent with the model, authoritarianism was negatively related to attitudes toward immigrants in the negative norm condition. However, authoritarians' tendency toward intolerance was attenuated when they thought that Americans in general had positive opinions about immigrants. Also as predicted, when societal norms were depicted as mixed, authoritarians' attitudes depended upon endorsement of humanitarian values: humanitarian authoritarians held positive attitudes and non-humanitarian authoritarians held the most negative attitudes toward immigrants. Implications for understanding the effects of authoritarian predispositions in varying social contexts are discussed.  相似文献

Background: Levels of psychological distress appear to be increasing in the workplace, in parallel with the growth of employee assistance programme (EAP) provision offering a range of talking treatments. However, such growth takes place in the absence of a substantive body of supporting research evidence despite a quarter of a decade of research activity. Aims: To analyse a national sample of EAP data and profile relative service quality on a set of key service indicators. Method: CORE System data profiles of over 28,000 clients were voluntarily donated by six EAP service providers. An established benchmarking methodology was used to assess the relative quality of EAP service provision compared with published CORE System benchmarks for NHS primary care and UK higher education student counselling services. Results: High quality data profiled an EAP service clientele who were quantifiably distressed, accessed treatment quickly, with the majority completing treatment and demonstrating high rates of recovery and/or improvement relative to published benchmarks from the NHS and HE comparative sectors. Limitations of the study and implications for practice and further investigation are considered.  相似文献

A large-sample test for the significance of the difference between two detection data points is developed based upon the assumptions of a one-parameter signal detectability model. In essence, the null hypothesis tested is that two observed data points belong to the samed' function.Portions of this research were supported by Contract DA-49-193-MD-2713 between the University of Washington and the U.
