Facedness and emotion related to lateral dominance, sex and expression type ☆

Abstract Facial asymmetry or “facedness” was reliably rated for nine different videotaped facial expressions of emotion, produced by 51 adults, and was significantly left-sided. This finding was related to right hemisphere dominance for emotion and for facial movement. No overall differences occurred for expression type or sex and handedness of subjects, but there were interactions.

Asymmetry in positive and negative facial expressions: Sex differences

Abstract Facial asymmetry (facedness) during posed emotional expression was correlated with measures of lateral dominance in 48 right- and left-handed normal adults. Positive and negative aspects of expression were refined by factor analysis. The finding for males that facedness for pleasant expressions was positively correlated with handedness and footedness may reflect linguistic factors. Discussion covers the nature of and laterality for positive/negative, communicative/reactive and approach/withdrawal dimensions of emotional expression.

Patients' Beliefs about Peptic Ulcer and Its Treatment

The Target Test: A Brief Laterality Measure of Speed and Accuracy

This paper describes a performance measure of lateral dominance, the Target Tests, which provides separate assessments of manual speed and accuracy within a relatively simple paper-and-pencil format. The Target Tests were administered to 111 normal adults, and scores were examined with respect to handedness, familial left-handedness, and sex. The tests significantly differentiated between right- and left-handers. Target scores were substantially correlated with the Harris Tests of Lateral Dominance, suggesting adequate reliability and validity. The means, standard deviations, and ranges for the preferred and nonpreferred hands for both handedness groups were nearly identical. The Target Tests provide a convenient instrument for assessing motoric lateralization of speed and accuracy in clinical and research settings.

Objective assessment of cooperation with an ulcer diet: relation to antacid intake and to assigned physician.

In order to measure adherence to a dietary regimen, patients assigned to diets for peptic ulcers were observed under conditions that permitted them to choose a more lenient diet by using an unauthorized diet card. The median patient took his prescribed ulcer diet on 76 per cent of all observed days, but one-fourth of the patients cooperated on less than 60 per cent of all days. The groups of patients assigned to various physicians differed in mean cooperation level. No relationship was found between a patients level of cooperation with the diet and his cooperation with his antacid regimen.

Formula for approximating plasma concentration

The footnote on p. 231 of our article (this JOURNAL 11:228‐237, 1970) was to indicate the primacy [of Dr. John G. Wagner] in providing a formula for approximating plasma concentrations and was not meant to imply that our formula was superior. We regret that our method of expressing this was ambiguous.
