Subjects were asked to match the lateral position of one tone, the “signal,” by means of another, the “pointer.” The two tones were presented alternately. The experimenter selected a combination of interaural time and intensity differences for the signal, and the subject adjusted the interaural time difference for the pointer until it seemed to him to be in the same lateral position as the signal. Subjects having normal hearing perceived the signal in two places, one strongly affected by the difference of level at the two ears, the other almost wholly dependent upon the difference of time.

The MMPI and MMPI-2 were administered to White and Hispanic-American subjects. Multivariate analyses revealed significant differences for three main effects: test form, ethnicity, and gender. Two-way interactions between gender and test form and between gender and ethnicity were both significant, but the other two-way interaction (Test Form x Ethnicity) and the third-order interaction (Test Form x Ethnicity x Gender) were not significant. Univariate analyses comparing MMPI and MMPI-2 revealed significant differences on 12 of 13 scales, and comparison of Anglos and Hispanics resulted in significant differences on 4 scales. When Anglos and Hispanics taking the MMPI and MMPI-2 were compared, however, no significant differences on any scales occurred. Results suggest that, for these Hispanic subjects, the MMPI-2 introduces no new or additional differences and may be employed and interpreted essentially the same as the MMPI.

Binge eating is a consequence of semistarvation in victims of war and famine and in volunteers in rare semistarvation experiments. These behaviors include bizarre mixing of ingredients and adulteration of food; eating inappropriate, soiled, or discarded food; secrecy; deception; and defensiveness. Drastic measures to resist overeating persist long after the semistarvation experience, even when food is plentiful. Binge eating, a central feature of bulimia and sometimes of anorexia nervosa, is prevalent in modern society, but the occurrence and frequency of semistarvation-related behaviors have not been well identified or quantified. A Semistarvation-Associated Behaviors Scale was constructed and administered to 40 college students. Among binge eaters, reports of bizarre semistarvation-like behaviors were common and frequent and were associated with dieting.

Hirsh found that when noise and signal are presented at one ear and noise alone to the other, the threshold for a tonal signal is lower than when the signal too is presented to both ears. The present study is concerned with this phenomenon as a function of the level of noise in the ear not receiving the signal, and as a function of the noise level in both ears. Findings are shown to be in agreement with Hirsh's and with predictions from a theory of masking phenomena.

The Graduate Record Examination (GRE) Verbal, Quantitative, and Analytic scores and undergraduate and graduate grade-point averages (U-GPA and G-GPA) for 320 Hispanics and 632 Anglos admitted to graduate school at the University of Texas at El Paso over the past 5 years were evaluated. Multivariate analyses revealed that Anglos scored significantly higher than Hispanics on both U-GPA and G-GPA and all three GRE scores. Multiple regression analyses for the ethnic group, with U-GPA and GRE scores used to predict G-GPA, showed higher correlations for the Anglos compared to Hispanics, although both had relatively poor predictive validity. The regression coefficients for all three GRE scores for the Hispanic group were zero, which reflects no relationship between the GRE and graduate grades; this makes the use of the GRE in selection of Hispanics for graduate school questionable.
