A standard facial caricature algorithm has been applied to a three-dimensional (3-D) representation of human heads, those of Caucasian male and female young adults. Observers viewed unfamiliar faces at four levels of caricature--anticaricature, veridical, moderate caricature, and extreme caricature--and made ratings of attractiveness and distinctiveness (experiment 1) or learned to identify them (experiment 2). There were linear increases in perceived distinctiveness and linear decreases in perceived attractiveness as the degree of facial caricature (Euclidean distance from the average face in 3-D-grounded face space) increased. Observers learned to identify faces presented at either level of positive caricature more efficiently than they did with either uncaricatured or anticaricatured faces. Using the same faces, 3-D representation, and caricature levels, O'Toole, Vetter, Volz, and Salter (1997, Perception 26 719-732) had shown a linear increase in judgments of face age as a function of degree of caricature. Here it is concluded that older-appearing faces are less attractive, but more distinctive and memorable than younger-appearing faces, those closer to the average face.

Recently, leadership theorists have commonly suggested that leaders should demonstrate new, arguably feminine, leadership behaviors. This contrasts with traditional stereotypes of leadership as strictly masculine. However, leadership research has a long history of recognizing two categories of leadership behaviors, initiation of structure and consideration, which appear to reflect stereotypically masculine and feminine behaviors. In the current study, 24 undergraduate volunteers rated traits of purported leaders based solely upon their viewing of the leaders' faces. These faces were visually impoverished so that the raters had to rely on implicit personality theories of leaders to guide their ratings. The results demonstrate that participants' ratings of purported leaders' masculinity and femininity indeed correlate very closely with their ratings of initiation of structure and consideration respectively.

The current paper reports for 80 undergraduates that risk aversion is greater among those with lower self-esteem scores on Rosenberg's Self-esteem Scale and those with higher scores on Budner's Intolerance of Ambiguity Scale.
