Testosterone and personality among college students and military veterans

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.     

A motor timing experiment implemented using a musical instrument digital interface (MIDI) approach

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).     

A multidimensional scaling analysis of vowel discrimination in humans and monkeys

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.     

Gender, relational role orientation, and affinity for animal rights

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.     

Remembering Nat Schoenfeld

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.     

Ethnic and Racial Differences in Life Stress Among High School Adolescents

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.

GRW and the tails problem

The GRW theory is a recent attempt to solve the measurement problem in quantum mechanics, and the tails problem is a well-known and potentially fatal criticism of the GRW theory. The first half of the paper is an exposition of the measurement problem, the GRW theory, and the tails problem. In the remainder of the paper, two methods of dealing with the tails problem are considered: first, altering the GRW theory so as to avoid the tails problem; and second, denying that the tails problem is more than a novel aspect of a universal vagueness in the way scientific theories relate to everyday language.
