Salivation: an assessment of food craving?

The validity of salivation as a measure of hunger and food craving was examined. Previous studies examining the relationship between salivation, food cues, and self-reports of hunger and food craving reported inconsistent results. The present study, using a modification of the Strongin-Hinsie-Peck (SHP) test to measure salivation, examined these relationships with overweight subjects. Salivation measures were taken on 25 subjects in a weight-control program during three experimental conditions: baseline I, food exposure and baseline II. While food exposure significantly increased the amount of salivation as compared to baseline, salivation did not correlate with self-reports of hunger or food cravings. Significant correlations were found for salivation, age. sex, and body fat. Implications of these results are discussed.     

Masking of tones by tones and of noise by noise

Using a two-alternative temporal forced-choice technique, two binaural detection experiments were performed. In the first, the detectability of a 250-Hz 128-msec tonal signal masked by a gated 70-dB SPL tone of the same frequency and duration was measured as a function of the level of the signal, the phase angle at which the signal was added to the masker, and the interaural phase difference of the signal. In the second experiment, the signal was a wideband (100-3,000 Hz) 128-msec Gaussian noise masked by a continuous Gaussian noise of the same bandwidth and coherent with the signal. The detectability of this noise signal was measured as a function of the same variables investigated in the first experiment. In both experiments detectability was found to follow a simple energy- or power-detection model when the interaural phase difference was 0 deg. When the interaural phase difference was 180 deg, the function relating the signal level required for a constant level of performance to the signal-masker phase angle is such that neither the Webster-Jeffress hypothesis nor Durlach’s E-C model accounts for the data. The data are reasonably well fit by a model proposed by Hafter and Carrier.     

Attitude Similarity,Attraction, and Physical Proximity In a Dynamic Space1

Previous research on physical proximity as an index of attraction based on attitude similarity has been limited to semifixed feature spaces. The present study tested the similarity-proximity relationship in a dynamic space. Female subjects' attraction to a female confederate was manipulated by means of false attitude information. The subjects then briefly interacted with the confederate in a dynamic space. Subjects' spatial behaviors were not directly related to attitude similarity-dissimilarity or to attraction. The implications of these findings for the generality of the similarity-proximity relationship and for research on nonverbal communication are discussed.     

Ambiguity of acceptance,social desirability,and dating choice

Male subjects differing in social desirability (likableness, physical attractiveness) chose a date from an array of females of three levels of physical attractiveness. Choices were made under two conditions: one where acceptance was assured regardless of whom subject chose; the other where acceptance was left ambiguous. The findings were as follows: (a) subjects selected a more physically attractive female when assured of acceptance than when acceptance was left ambiguous; (b) subjects estimated that highly physically attractive females were less likely to accept them as a date than were either moderately physically attractive or physically unattractive females; (c) subjects' self-ratings of their likableness were not related to the physical attractiveness of their choices under either choice condition nor to their estimates of their chances that the females would accept them as a date; and (d) subjects' self-evaluated physical attractiveness, although unrelated to the physical attractiveness of the subjects' choices, did relate to subjects' estimates of their chances of acceptance. Highly physically attractive subjects estimated their chances of acceptance as better than did subjects who considered themselves low in physical attractiveness. The implications of the findings for the “matching hypothesis” are discussed.     

The effects of covert and overt modeling on assertive behavior

Three modeling therapy formats (overt modeling with a standard hierarchy of situations. covert modeling with the standard hierarchy, and covert modeling with a self-tailored hierarchy) were compared to assess their relative efficacy in developing assertive skills. Half the subjects in each treatment condition received or did not receive generalization training. Significant within-group improvement was indicated on four self-report measures. Overall, the results suggest that covert modeling was as effective as overt modeling or covert modeling plus self-tailoring for instating assertion among nonassertive college women.     

Group aversion by imaginal, vicarious and shared recipient-observer shocks

Sixty college students completed waiting control or alternative group aversion conditions, matched for severity and chronicity of nail-biting. Treatments spanned four sessions. Imaginai aversion (covert sensitization) clients visualized shocks to themselves. Vicarious aversion clients observed shocks to a trained model. A ‘hotseat’ format randomized a few actual shocks to each client with observing peers shocked on remaining trials. The predominant pattern of outcome and subjective impact results was as follows: Hotseat consistently best; vicarious typically second; imaginal usually third; controls worst. Clinical and conceptual issues are raised.     

E pluribus unum and civil harmony at election time

One way to formulate the task of the public theologian at election time is to interpret America's motto, e pluribus unum (out of many, one). Civility both presumes oneness while promoting oneness. After four years of ceaseless divisiveness from the White House, America needs political leadership that promotes a sense of belonging that includes persons of all races, ethnicities, economic classes, ages, genders, and country of origin. The public theologian combats xenophobia and the fear of replacement by demanding police reform, establishing a comprehensive national health delivery system, and comforting those who are anxious about their future in the unum.
