Relationships of serum and saliva to personality were examined among 401 college students in four laboratory studies and 5,236 military veterans in one archival study. Among the students, there were few relationships between testosterone and traditional personality measures. Among the veterans, MMPI scores and DSM-III diagnoses showed testosterone related to drug and alcohol abuse, antisocial and generally intemperate behavior, and effective disorders. Consistent with social control theory, correlations were higher among veterans who were lower in socioeconomic status. It appears likely that testosterone has innate effects that are socially undesirable but can be attenuated by bonds between the individual and society. Effect sizes were small, suggesting that testosterone will have noticeable effects only in large populations or individuals who differ markedly from the population mean. Further research should focus upon antisocial correlates of testosterone and conditions that produce marked changes in testosterone levels. 相似文献

The musical instrument digital interface (MIDI) offers a way for perception and behavior researchers to implement high-quality experiments using inexpensive, commercially available hardware and software. We describe the MIDI and illustrate its applicability to research using a replication of the oscillator signature finding reported recently by Collyer, Broadbent, and Church (1992, 1994). 相似文献

Multidimensional scaling (MDS) was used to compare perceptual maps for 10 synthetic English vowels in humans and Old World monkeys (Macaca fuscata andCercopithecus albogularis). Subjects discriminated among the vowels using a repeating background procedure, and reaction times were submitted to an MDS analysis to derive measures of perceived similarity. The dimensions that emerged related to the frequencies of the first(F1), second(F2), and third(F3) formants. Human data indicated a good match to previous MDS studies using rating procedures or confusion matrices: The dominant dimension mapped onto vowelF2, the phonetically most important formant, and the second and third dimensions mapped ontoF1 andF3, respectively.For monkeys, equal weightings occurred forF1 andF2, andF3 was not clearly represented. Monkey sensitivity to the formants appeared to relate to formant amplitudes. If monkeys are giving an accurate representation of the psychoacoustic relations among the formants, then our human results suggest that species-specific mechanisms, reflecting the salience of the phonetic feature of advancement, may contribute to vowel coding in humans. 相似文献

In the present study, we compared the effects of two processing modes on the updating of the location and orientation of a previously viewed object in space during a guided walk without vision. In Experiment 1, in order to measure the error for initial perception of object’s orientation, 12 subjects rotated a miniature model until it matched the memorized orientation of its counterpart object in space. In Experiment 2, they attempted either to keep track of the object continuously (in the object-centered [OC] task) or to estimate the object’s perspective only at the terminal vantage point given the trajectory they walked (in the trajectory-centered [TC] task). Subjects indicated the location of the object by facing it, and then rotated the model in order to indicate its orientation from the new vantage point. Results showed that, with respect to the TC mode, the OC mode induced a slowdown of the subjects’ self-paced locomotion velocity for both linear and angular movements, and a decrease of the latencies as well as smaller absolute errors for the orientation-of-the-object response. Mean signed errors on object’s orientation were equivalent for both processing modes, suggesting that the latter induced different allocations of processing resources on a common representation of space updated by “path integration.” 相似文献

Research based mainly on non-national samples reports a greater affinity for animal rights among women than men, and proposes a greater relational role orientation among women that emphasizes caring for others to explain this difference. Using a recent national sample comprised of 11% African American and 89% white American respondents, we find that a relational role orientation fails to account for women’s greater support of animal rights. It does provide minor help in distinguishing animal rights advocates from nonadvocates, but only among women and only on one of two measures of animal rights support. We conclude by proposing women’s structural locations as well as the interplay between these locations and women’s role socialization as alternate explanations for gender differences in affinity for animal rights. 相似文献

William Nathan Schoenfeld was born in New York City on December 6, 1915, and died in Sun City West, Arizona, on August 3, 1996. He was an undergraduate at the College of the City of New York, where he received a BS degree in 1937. He received his PhD from Columbia University in 1942 and then continued there as a faculty member, advancing from lecturer to full professor. In 1966 he moved to Queens College of the City University of New York, where he remained until his retirement in 1983. During his years at Queens, he also took on visiting appointments in Brazil, Mexico, and Venezuela. In retirement, he spent roughly a decade in Israel, where he occasionally taught as a visiting professor at the Hebrew University of Jerusalem. He returned to the United States for his final years. He is survived by his wife, Melanie, their three children, Rivka, Joshua and Naomi, and a son, Mark, from a previous marriage. 相似文献

L. A. Slavin, K. L. Rainer, M. L. McCreary, and K. K. Gowda's (1991) Multicultural Model of the Stress Process was used as the basis for exploring ethnic and racial differences in the life stress process among 103 Black, 129 Hispanic, and 105 White high school students from a multiethnic, predominantly minority, large urban school district. Cross-group comparisons were made on life stress exposure, appraisal of negative event impact, social support, and psychological symptomatology. White adolescents reported more negatively impactful stressful life events and lower levels of received social support than did Black or Hispanic adolescents. Minority status predicted ethnic and racial differences independent of socioeconomic status. 相似文献

With the end of the cold war, issues of environment and economic development are assuming greater international salience.
By the 1970s, environmental degradation was becoming pervasive, with growing global effects. Increasingly, global and emergent
globalized problems are forcing environmental interdependence on the world. Transboundary threats cannot be addressed unilaterally
by any single country or group of countries. The global environmental agenda is reviving the North-South debate and rejuvenating
the Third World coalition in international fora.
The encouragement of environmentally sustainable forms of industrialization in the South requires expanded and improved international
cooperation. However, the North’s greater resources and greater responsibility in causing global environmental degradation
require its continuing involvement in the search for solutions, including ones applicable to newly industrializing countries.
In June 1992, the largest intergovernmental conference ever held was convened in Rio de Janeiro to address these issues: the
United Nations Conference on Environment and Development (UNCED, or the Earth Summit). It produced a consensus action plan
of about 700 pages: Agenda 21. Agenda 21 presents massive challenges for international cooperation as well as for national
and private actors and scientific and technical institutions. It reflects a complex configuration of demands for institutional
arrangements that support environmentally sustainable technical and socioeconomic change. One of the most consistent of the
Agenda 21 themes, and one of the most intractable issues, concerns “access to technology.” This can be as straightforward
as diagnosing and improving the efficiency of a production process in a small manufacturing firm, or as complex as engineering
a technological revolution in which production and consumption take place with virtually no material or energy loss to the
environment. The selection of entry points for action is a critical strategic problem as well as an important operational
issue.
In this paper I identify and describe new initiatives intended to improve the environmental performance of industry in the
South, and find that they largely aim to promote incremental industrial innovation through international technology transfer
and diffusion. This strategy raises many questions about how to promote effective technology transfer and diffusion.
