Evidence for holistic processing of faces viewed as photographic negatives

Inversion and photographic negation both impair face recognition. Inversion seems to disrupt processing of the spatial relationship between facial features ('relational' processing) which normally occurs with upright faces and which facilitates their recognition. It remains unclear why negation affects recognition. To find out if negation impairs relational processing, we investigated whether negative faces are subject to the 'chimeric-face effect'. Recognition of the top half of a composite face (constructed from top and bottom halves of different faces) is difficult when the face is upright, but not when it is inverted. To perform this task successfully, the bottom half of the face has to be disregarded, but the relational processing which normally occurs with upright faces makes this difficult. Inversion reduces relational processing and thus facilitates performance on this particular task. In our experiments, subjects saw pairs of chimeric faces and had to decide whether or not the top halves were identical. On half the trials the two chimeras had identical tops; on the remaining trials the top halves were different. (The bottom halves were always different.) All permutations of orientation (upright or inverted) and luminance (normal or negative) were used. In experiment 1, each pair of 'identical' top halves were the same in all respects. Experiment 2 used differently oriented views of the same person, to preclude matches being based on incidental features of the images rather than the faces displayed within them. In both experiments, similar chimeric-face effects were obtained with both positive and negative faces, implying that negative faces evoke some form of relational processing. It is argued that there may be more than one kind of relational processing involved in face recognition: the 'chimeric-face effect' may reflect an initial 'holistic' processing which binds facial features into a 'Gestalt', rather than being a demonstration of the configurational processing involved in individual recognition.     

Transferability of a role-oriented interest Inventory from men to women in church-related occupations

This study considers the feasibility of using the Inventory of Religious Activities of Interests and the extensive data for men associated therewith in the counseling of women who may be interested in entering occupations related to the Protestant Church. Mean scores on the ten scales of the Inventory for men and women in nine categories of church-related occupations and for the total sex groups were compared in respect to similarity of shape of mean score profile and in respect to the level of mean scores. In addition, the ability of the Inventory to differentiate among groups (11 for women; 10 for men) for the sexes separately was considered. The results suggest that while men and women as total groups appear to differ in their interests as measured by the IRAI, the data for men and women in the respective specialties are sufficiently similar in respect to profile shape and mean score level to justify the use of the Inventory and the normative data for men in the counseling of women. The results suggest the Inventory differentiates among subgroups of men more effectively than it does among subgroups of women. But there are data to suggest that this difference may be more apparent than real.     

Rat data which suggest alcoholic beverages should be swallowed during chemical aversion therapy,not just tasted

There were four pretraining procedures: A, in which rats drank sugar water prior to lithium sickness: P. in which sugar water was passed over the tongue prior to lithium sickness: Li, in which no taste experience preceded lithium sickness: NPT. in which the rats were exposed neither to the sugar water nor to lithium sickness. Lithium was then used to produce aversions to some other solution by dividing each of the pretraining groups into four subgroups. The solutions were novel NaCl, novel vinegar, novel alcohol, or familiar alcohol. Regardless of which solution was made aversive. the A pretraining procedure produced the strongest aversions and the Li procedure produced the weakest aversions. In the final phase, the preference for sugar water was tested. The A procedure produced far stronger aversions than the P procedure.     

The work of worrying in children undergoing surgery

This study examined the relationship involving children's level of anxiety, defensiveness, and play patterns 1 week prior to, during, and 1 week after hospitalization for minor surgery. A 7-month follow up was also conducted in order to assess the children's recall for hospital events and coping style. The results suggested that two classes of children could be identified. The children in one group distinguished themselves in terms of their disposition to engage in the work of worrying (i.e., were low defensive prior to hospitalization, actively played with stress-related toys prior to hospitalization, and reported minimal distress and anxiety following surgery). Those in the second group were highly defensive, avoided playing with stress-related toys, and reported most anxiety following surgery. The parallel between children and adult patterns of dealing with surgery was considered in terms of Janis's (1958) model of coping with psychological stress.This research was supported by a grant from Canada Council, Grant No. S72-2314-52. The authors wish to thank the staff and children of Our Lady of Lourdes School of Waterloo, the Kitchener-Waterloo Hospital, and St. Mary's General Hospital for their cooperation. Appreciation is extended to Dr. Pat Bowers and Dr. Barney Gilmore for their help during the formative stages of this study and for their many constructive suggestions.     

Age,job complexity,satisfaction, and performance

Job complexity was measured for jobs in a Public Agency. Perceptions of job complexity were obtained from self-reports of 133 employees. Independent measures were obtained from interviews with the subjects. Career stages, based upon age groupings, were found to moderate the relationship between (1) job-satisfaction and perceived job complexity and (2) job-performance and independently rated job complexity. These results are discussed in light of the current literature.     

Using FMRI to study the neural correlates of virtual reality analgesia

Excessive pain during medical procedures, such as burn wound dressing changes, is a widespread medical problem and is especially challenging for children. This article describes the rationale behind virtual reality (VR) pain distraction, a new non-pharmacologic adjunctive analgesia, and gives a brief summary of empirical studies exploring whether VR reduces clinical procedural pain. Results indicate that patients using VR during painful medical procedures report large reductions in subjective pain. A neuroimaging study measuring the neural correlates of VR analgesia is described in detail. This functional magnetic resonance imaging pain study in healthy volunteers shows that the large drops in subjective pain ratings during VR are accompanied by large drops in pain-related brain activity. Together the clinical and laboratory studies provide converging evidence that VR distraction is a promising new non-pharmacologic pain control technique.
