Sex differences on a measure of conformity: comments on a recent study

Reysen and Reysen's recent article made a contribution to understanding of sex differences by interpreting the results through the lens of conformity research. Reinterpretation could refer to differences in perceptual sensitivity. The results, then, are theoretically and empirically consistent with the literature.     

Auditory--visual cross-modal perception of communicative stimuli in tufted capuchin monkeys (Cebus apella)

Research on cross-modal performance in nonhuman primates is limited to a small number of sensory modalities and testing methods. To broaden the scope of this research, the authors tested capuchin monkeys (Cebus apella) for a seldom-studied cross-modal capacity in nonhuman primates, auditory-visual recognition. Monkeys were simultaneously played 2 video recordings of a face producing different vocalizations and a sound recording of 1 of the vocalizations. Stimulus sets varied from naturally occurring conspecific vocalizations to experimentally controlled human speech stimuli. The authors found that monkeys preferred to view face recordings that matched presented vocal stimuli. Their preference did not differ significantly across stimulus species or other stimulus features. However, the reliability of the latter set of results may have been limited by sample size. From these results, the authors concluded that capuchin monkeys exhibit auditory-visual cross-modal perception of conspecific vocalizations.     

Ordinal representation of numeric quantities by brown capuchin monkeys (Cebus apella)

Using techniques established by E. M. Brannon and H. S. Terrace (2000) with rhesus macaques (Macaca mulatta), the authors tested the ability of brown capuchins (Cebus apella) to order arrays of items ranging in quantity from 1 to 9. Three monkeys were trained on a touch screen to select the quantities 1-4 in ascending order. The monkeys exhibited successful transfer of this ability to novel representations of the quantities 1-4 and to pairs of the novel quantities 5-9. Patterns of responding with respect to numeric distance and magnitude were similar to those seen in human subjects, suggesting the use of similar psychological processes. The capuchins demonstrated an ordinal representation of quantity equivalent to that shown in Old World monkeys.

Intrinsic properties

Conclusion It seems that no quasi-logical analysis of naturalness, intrinsicality, or duplication is possible; this at least in part lends credibility to the practice of taking one as a primitive. And I have argued that Lewis's analysis of intrinsicality is indeed successful, Dunn's objections notwithstanding. There are other important questions about Lewis's project that I have not answered. Is his analysis of duplication successful? Does the notion of naturalness make sense? Even if naturalness cannot be defined, can it be explained in an illuminating manner? Rather than taking one of the notions as primitive, should we analyze the notions in terms of some other extra-logical notion? Important questions, but questions for another time.     

EMOTIONAL CONTAGION Gender and Occupational Differences

Theorists have proposed that men and women and those in various occupational groups should differ in their susceptibility to primitive emotional contagion. Study 1 was designed to explore the extent to which gender and occupation affected respondents' self-reports of emotional contagion, as measured by the Emotional Contagion (EC) scale. As predicted, women in a variety of occupations secured higher total EC scores than did men. Study 2 was designed to determine the extent to which gender affected self-reports of emotional contagion (again as measured by the EC scale) and actual responsiveness to others' emotions. As predicted, women received higher EC scores, reported sharing the targets' emotions to a greater extent, and were rated by judges as displaying more emotional contagion than did men.
