In a sample of 53 right-handed, young adult males, asymmetry was examined in the size of 11 facial regions, in total area, and in emotional expression of the face at rest. In the complete sample no evidence was obtained of consistent asymmetry in size of facial regions, in facial area, or in emotional expression. There was, however, an interaction between family history of sinistrality and sighting dominance in facial asymmetry for the pleasantness/unpleasantness of facial expression. The findings suggest that previously established asymmetries in phasic emotional displays are not an outcome of expressive or morphological asymmetries of the face at rest.

Two experiments were conducted to investigate the relations among hypnotic susceptibility, lateralization of actual seating behavior, and seating preference.In the first experiment it was found that females who sat on the right side of a classroom were more hypnotically susceptible than females who sat on the left. Males who preferred right-side seating were more susceptible than males with left-side preferences. In the second experiment subjects were randomly ' assigned to seats in order to determine whether seating location itself affected responsiveness to hypnosis. No association between lateralization of actual seating and hypnotic susceptibility was found. Replicating Experiment 1, males who preferred right-side seating were more hypnotically susceptible than males with left-side preferences. Lateralization of seating behavior has been found previously to be a function of hemisphericity. The results of both experiments indicate that lateralization of seating behavior may be used to investigate the relation between hemisphericity and hypnotic susceptibility.

Quantitative studies of the influence of the surface composition on the creep of zinc single crystals under constant loads have been carried out. The creep curves of crystals with clean and oxidized surfaces were obtained in air and in acid. It is shown that a continuous layer of oxide strengthens the crystal only at low loads, and that the presence of cracks in this layer allows the metal to creep at its normal rate. These facts support the theory that the oxide film acts to relieve the metal of part of the load. An increase in creep rate is observed when the pure metal surface is treated with dilute mineral acids. The heat liberated by the reaction is considered as a possible explanation of the sudden increase in creep rate when the surface layer of the crystal is removed. The normal creep curves of unoxidized crystals in air may be described by an empirical equation of a new form, and its application to other types of curves obtained is discussed.
