Aberrant first fixations when looking at inverted faces in various poses: The result of the centre‐of‐gravity effect?

Face recognition is essential in everyday human life, and all faces are encountered in different poses. However, when a face is inverted, difficulties arise for recognition and eye movements may (Barton, Radcliffe, Cherkasova, Edleman, & Intriligator, 2006) or may not be disrupted (Williams & Henderson, 2007). The present study explored the effects of orientation and pose on recognition and eye movements during a standard old/new recognition task in order to resolve whether inversion disrupts eye movements. Eye‐tracking data looked at the first fixations, the number of fixations, and the duration of fixations over a face. A standard inversion effect was observed, but the three‐quarter view advantage was not observed. Eye‐movement data revealed that the eyes were the most sampled feature (in terms of first fixation, number of fixations, and duration of fixation) for all upright faces, however, other features were sampled first for inverted faces. These results are consistent with Barton et al.'s (2006) but not Williams and Henderson's (2007) findings: possible explanations for this are discussed with the caveat that the same images were used from learning to test.     

A developmental study of the own-age face recognition bias in children

The own-age bias is one in which people recognize faces of people their own age more accurately than faces of other ages (e.g., Anastasi & Rhodes, 2005, 2006) and appears to be, at least, partially based on experience (Harrison & Hole, 2009). Indeed, Hills and Lewis (2011a) have shown that 8-year-old faces are more accurately recognized by 8-year-old children than by 6- or 11-year-old children, suggesting the own-age bias develops rapidly. The present study explores the own-age bias in a developmental study in participants aged 6-10 years. Ninety participants (divided into 3 groups of 30 on the basis of their age at the first time of testing) undertook a standard old/new recognition paradigm in which their recognition accuracy was measured for 8- and 20-year-old faces. Results showed that when the participants were 8 years old, they recognized 8-year-old faces more accurately than when they were 7 or 9 years old. This effect was found to be based on mechanisms that differ from simple developmental improvement. This is the first study to show the development of the own-age bias in face recognition using a longitudinal design. These results show that the face recognition system is updated on the basis of recent experience and/or motivation to process faces, creating recognition biases.     

UNDERSTANDING STRESS IN FEMALE AND MALE LAW ENFORCEMENT OFFICERS

Gender issues in the male-dominated profession of law enforcement have not been closely examined. In the current study, 52 female officers of a state highway patrol agency were matched with 52 male officers. Participants completed a confidential assessment packet to examine their satisfaction with work, perceived stress, physical symptoms, daily hassles, and aspects of burnout. Results suggest that male officers experience a greater degree of perceived stress and emotional exhaustion and greater dissatisfaction with their work than do women. In female officers, perceived stress was related to physical symptoms, dissatisfaction with the nature of the work, dissatisfaction with co-workers, and feelings of emotional exhaustion. In male officers, perceived stress was related to physical symptoms, dissatisfaction with co-workers, dissatisfaction with work, and emotional exhaustion. Gender differences in terms of officers'expectations and beliefs about the profession as well as the possible differential effects of marital status on occupational stress are discussed.
