The relationship between frontalis muscle activity and self-reports of headache pain

The relationship between levels of frontalis muscle activity and self-reports of pain was evaluated in two studies. In Study I frontalis muscle activity and self-reports of pain collected during biofeedback treatment of muscular contraction headache clients were correlated. In Study II frontalis EMG activity was increased and decreased using biofeedback techniques while concurrent reports of headache pain were recorded. The results of Study I indicated a significant relationship between EMG activity and reported headache pain for only two of the five subjects studied. The biofeedback procedures in Study II were associated with reliable increases and decreases in EMG activity. Concordance between EMG and pain reports occurred only during the EMG increase condition. Overall correlations were significant for one of the 2 subjects. The results suggest that EMG activity may not be sufficient to account for pain reports in all chronic headache clients, and variables other than EMG activity may be influencing reports of pain in some patients.     

Social influence on attitudes and on anchoring of congeneric attitude scales

Criteria for distinguishing between attitude and response scale effects in “after-only” studies of source-recipient discrepancy were developed and applied in two experiments. These criteria refer to congeneric scales (i.e., multiple measures of the the same property, which may differ in origin, unit, and reliability). Persuasive information may function as a scale anchor, in which case it is expected to affect only that response scale to which it directly pertains. Alternatively, it may convice recipients to change attitudinal positions, and produce effects on all congeneric scales. In one experiment, the self-proclaimed leniency-sternness of a presiding judge in a manslaughter case was varied along with the sentence he imposed and his trustworthiness. In the second study, only the sentence was manipulated, while both leniency ratings and sentencing were measured as dependent variables. Both analyses revealed support for the response scale interpretation, in that effects were observed only on those scales that were directly manipulated.     

Sexual activity and contraceptive use among low-income urban black adolescent females.

A modified form of Nathanson and Becker's (1983) Health Belief Model Questionnaire and other measures designed to assess cognitive processing were administered to low-income black adolescent female clients of an inner-city comprehensive health care clinic. The purpose of the study was to explore determinants of sexual activity and contraceptive use. Subjects were classified as not sexually active (n = 50), sexually active/noncontracepting (n = 20), or sexually active/contracepting (n = 72). Not sexually active subjects tended to be younger, more career motivated, to have a father at home, to be more influenced by family values, and to have more conservative attitudes regarding adolescent sexuality than did sexually active subjects. Sexually active/noncontracepting subjects tended to report fewer benefits and more barriers to the use of contraception. Level of cognitive processing did not differ among the three groups, but was at a lower-than-expected level for age. Finally, inconsistent contraceptive use was common to both sexually active groups.     

The influence on recognition of spoken words that are misperceived

Two experiments were performed that involved an initial word-identification task in which the acoustic signal was degraded by either 50% or 60% compression of the recorded words. A control group was tested at the original recording rate (0% compression). The compression manipulation was successful in increasing the number of identification errors. During the second stage of the experiments, words were read at a normal rate. In Experiment 1, the subjects indicated whether each word had appeared on the prior list, and in Experiment 2, the subjects estimated the number of times each word had been read on the prior list. The false-negative rate decreased and frequency ratings increased as a function of the number of prior presentations (one, two, or three) of the target words. The most interesting result was that the effect of repetitions was present even for words that had been misperceived.     

The salience of the self in responses to inequity

Previous research has shown that people strive to conform with the standards of significant others in distributive justice. The present research was concerned with the role of attention to the self in the same paradigm. If people are motivated to personally evaluate their own behavior as fair, then self-focus should result in heightened attempts to redress an overpayment inequity. After the subject's criterion of a fair wage was assessed, they were paid either that amount or double it. Orthogonal to this manipulation, subjects were either made objectively self-aware (OSA) or not, by the presence or absence of a mirror. Consistent with the hypothesis, overpaid OSA subjects did more work, but of a poorer quality, than overpaid not-OSA subjects. This was taken as evidence of more zealous attempts to restore a sense of equity, implicating a greater personal need to eliminate the injustice when the discrepancy between pay level and a personal standard of fairness was made more prominent to the self.     

Background and Focal Environmental Conditions of the Home and Attention in Young Children1

A conceptual distinction is drawn between two aspects of the perceptual field, focal features which the individual selectively engages and extraneous background conditions which serve as a context within which these activities occur, and a study is described which examined the relationship between these aspects of the home environment and attentional skills in young children. Ninety-four families with kindergarten age children participated in the project. Interviews and observations were conducted in the homes in order to assess background conditions (e.g., noise and activity levels) and variation and patterning of focal features (e.g., furnishings), and tasks designed to assess attentional skills were administered to the children. The results indicated that children from homes with high noise levels had longer response latencies on a visual search task and also subsequently recognized fewer incidental aspects of the task than did children from quieter homes. Furthermore, the former group appeared to be less distractible, i.e., less responsive to an auditory distractor. Neither variation nor patterning of focal features was found to be associated with task performance. In general, the findings are interpreted as indicating the adverse effects of high noise levels in the home on attentional skills in spite of apparent adaptation, i.e., lower distractibility, to these conditions.     

Cross-cultural model testing: toward a solution of the etic-emic dilemma

A model for the prediction of behavior from attitudinal components, developed by Triandis, was tested with samples of U.S. and Mexican women, and with fertility relevant behaviors. The elements of the model are etic, but the operationalizations of the various variables were done emically. Results support the model in both cultures. While the predictive utility of the model is equivalent in two cultures, there are social class differences on which component of the model is most emphasized. The U.S. upper-middle-class sample and the Mexican upper-middle-class sample emphasized the person's attitude toward the act, while the Mexican lower SES (socio-economic status) sample emphasized the person's normative beliefs (moral obligations).
