TEMPORAL INTEGRATION OF PERCEPTUAL RESPONSE TO SUPRALIMINAL ELECTRICAL STIMULATION

E kman , G., F röberg , J. & F rankenhaeuser , M. Temporal integration of perceptual response to supraliminal electrical stimulation. Scand. J. Psychol ., 1968, 9, 83–88.—The effect of duration of electrical stimulation on perceived unpleasantness was investigated in 10 subjects. Duration of stimulation ranged from 0.05 to 3.00 sec. Three levels of intensity were investigated representing 2, 3, and 4 times the individual sensation threshold. For all stimulus intensities perceived unpleasantness was a simple logarithmic function of stimulus duration over the whole temporal range. This relation describes the trend of both the group data and the data from most individual subjects. The results support previous findings over a narrower temporal range and agree with results recently obtained in several additional sense modalities.     

What you say and how you say it: the contribution of speech content and voice quality to judgments of others

In three studies, judgments based on separated channels (speech content, voice quality, face alone and body alone) were correlated with judgments based on combined channels (speech, face + speech, and face + body + speech). The judges observed spontaneous behavior in two different types of interview situations and rated various aspects of the behavior. Correlations between separated and combined channels varied significantly depending on the kind of behavior judged, the attribute rated, and whether other channels of information were available.     

From flawed self-assessment to blatant whoppers: the utility of voluntary and involuntary behavior in detecting deception

Malingering occupies a range on a continuum from biased self-perception to conscious, deliberate, serious lies. One aspect of this continuum is the element of self-conscious or deliberate control. Suggestions from Darwin's writings concerning the role of voluntary and involuntary activation of the facial muscles are examined and illustrated with data from a 40 year program of research on deception. The impact of the voluntary-involuntary distinction on the appearance, timing, symmetry and cohesion of facial expressions of emotion is explained. Data relevant to changes in vocal and gestural aspects of demeanor in honest and deceptive behavior are also reviewed. The relevance of these laboratory-based findings on the voluntary control of nonverbal behavior in assessing some types of malingering is discussed.     

Linkages between facial expressions of anger and transient myocardial ischemia in men with coronary artery disease

The authors examined whether facial expressions of emotion would predict changes in heart function. One hundred fifteen male patients with coronary artery disease underwent the Type A Structured Interview, during which time measures of transient myocardial ischemia (wall motion abnormality and left ventricular ejection fraction) were obtained. Facial behavior exhibited during the ischemia measurement period was videotaped and later coded by using the Facial Action Coding System (P. Ekman & W. V. Friesen, 1978). Those participants who exhibited ischemia showed significantly more anger expressions and nonenjoyment smiles than nonischemics. Cook-Medley Hostility scores did not vary with ischemic status. The findings have implications for understanding how anger and hostility differentially influence coronary heart disease risk.     

Contradictions in the study of contempt: What's it all about? Reply to Russell

A number of methodological problems make it difficult to draw any conclusions from Russell's studies of contempt, including a task which may maximize the influence of unfamiliarity with the task, and instructions which may encourage observers to rate many rather than few emotions. We raise questions also about ecological validity, and the appropriateness of using still photographs to study the influence of context on the jugments of emotion.     

Subjective geographic distance: A multidimensional comparison

The interdistances between thirteen places situated in different parts of the world were estimated by 60 subjects. The estimates were analysed by Kruskal's multidimensional technique and, after a cosine transformation, by factor analysis. It was found that both methods yielded the same three-dimensional solution. Also a two-dimensional configuration could describe the data, and it was shown that this configuration contained representations of unidimensional ratings obtained in other studies. This investigation was supported by grants from the Bank of Sweden Tercentenary Fund and the Swedish Council for Social Science Research. Died 5 May 1971.
