Facial expressions of pain in muscle-contraction headache patients

Using a judgment and component analysis of facial actions, 14 muscle-contraction headache (MCH) patients were videotaped in headache and nonheadache states. In addition, patients were also required to undergo a resting physiological assessment (frontalis electromyography, temporal blood volume pulse, and heart rate), reaction-time task, and complete self-report measures of pain state and mood. Headache and nonheadache state of MCH patients were reliably identified by 20 observers. Characteristics of facial expressions that occurred most frequently in the headache state included furrowed eyebrows, closed eyes, slow eye blinks, lip pursuing, facial grimacing, and flat facial affect. Headache state was also associated with increased latency to respond to an auditory tone and mood disturbances, but no differences in baseline physiological activity were observed. Our findings provide support for the utility and clinical relevance of judgment and component analysis of facial actions in MCH patients.     

Peer facilitation of generalization in a preschool classroom

Two 5-year-old deviant preschoolers taught each other, as peer-tutors, to identify pictorial figures describing prepositional relationships. During training sessions monitored by the experimenter, the child in the peer-tutor role presented stimulus materials and provided consequences for the responses of the child in the tutee role. An assessment of generalization by each child to an academic classroom setting occurred each day. The data showed that the peer-tutor could facilitate generalization, when the tutee was probed in the peer-tutor's presence. However, it was found that the salience of the peer-tutor's presence was critical to this effect. In particular, when the peer presented the stimuli or offered occasional consequences for some correct responses, generalization was greatly enhanced.This research was supported in part by PHS Training Grant HD 00183, Research Grant MH 11739, and a Dissertation Fellowship from the University of Kansas. Appreciation is expressed to the classroom teachers, Scott Simmons, Janet Wedel, Sue Parker, and Tena McEachern, for their patience and cooperation in the implementation of these procedures, and to Merril Stokes, for her help and encouragement during this study.     

Southern traditionalism and sex-role ideology: A research note

Sociological literature, as well as popular folklore, suggests the existence of a Southern regional subculture, of which sex-role traditionalism is an integral part. To test the empirical validity of this assumption, the present study employed the 1975 National Fertility Study data, a probability sample of 3,403 currently married white women, of whom eight sex-role questions were asked. A factor analysis of these questions was used to calculate a sex-role summary score for each respondent. Wife's employment in 1975 and her attainment of high levels of education were the two strongest predictors of a nontraditional sex-role score. The sex-role attitudes of Southern and non-Southern women did not differ significantly. The implications for research and policy are discussed.An earlier version of this article was presented at the Annual Meeting of the Southern Sociological Society, Atlanta, Georgia, April 4–7, 1979.

Assessing the Utility of Compound Trait Estimates of Narrow Personality Traits

It has been argued that approximations of narrow traits can be made through linear combinations of broad traits such as the Big Five personality traits. Indeed, Hough and Ones (2001 Hough, L. M., &; Ones, D. S. (2001). The structure, measurement, validity, &; use of personality variables in industrial, work, and organizational psychology. In N. Anderson, D. S. Ones, H. K. Sinangil, &; C Viswesvaran (Eds.), Handbook of industrial, work, and organizational psychology (Vol. 1, pp. 233–277). London, UK: Sage.[Crossref] , [Google Scholar]) used a qualitative analysis of scale content to arrive at a taxonomy of how Big Five traits might be combined to approximate various narrow traits. However, the utility of such compound trait approximations has yet to be established beyond specific cases such as integrity and customer service orientation. Using data from the Eugene-Springfield Community Sample (Goldberg, 2008 Goldberg, L. R. (2008). The Eugene-Springfield community sample: Information available from the research participants. Eugene: Oregon Research Institute. [Google Scholar]), we explore the ability of linear composites of scores on Big Five traits to approximate scores on 127 narrow trait measures from 5 well-known non-Big-Five omnibus measures of personality. Our findings indicate that individuals' standing on more than 30 narrow traits can be well estimated from 3 different types of linear composites of scores on Big Five traits without a substantial sacrifice in criterion validity. We discuss theoretical accounts for why such relationships exist as well as the theoretical and practical implications of these findings for researchers and practitioners.     

Animacy increases second target reporting in a rapid serial visual presentation task

Attentional blink occurs when two target items, T1 and T2, are presented within brief moments of each other in a series of rapidly presented items and participants fail to report T2. The purpose of the present study was to examine the effect of characteristics of T2 on T2 reporting. Participants (N = 67) completed 4 blocks of 40 trials. Each trial consisted of 15 images, two of which were designated as T1 and T2. T2 was manipulated in three ways: animacy (animate or inanimate), threat (threatening or nonthreatening), and lag (200 ms or 400 ms after T1). The results indicated that more T2s were reported at the longer lag and that animate objects were reported more often than inanimate objects at both lags. Threat did not have a significant effect on T2 reporting although it interacted with lag: threatening objects were reported more frequently than nonthreatening objects at lag 2 but this trend reversed at lag 4. The results were consistent with the animate monitoring hypothesis, which claims that animate objects, because of their importance in ancestral environments, attract attention more easily than inanimate objects. Animate objects appear to capture attention more easily than inanimate objects as second targets in a rapid serial visual presentation task. This result is similar to animacy advantages reported with other attention tasks and with memory tasks.
