The pigeon's variability discrimination with lists of successively presented visual stimuli.

Pigeons previously trained to peck 1 button (same) after the successive presentation of 16 identical pictures and to peck a 2nd button (different) after the successive presentation of 16 nonidentical pictures were tested on lists involving different degrees of variability, different list lengths, and different temporal organizations of list items. The pigeons' performances on this successive same-different task revealed a strong sensitivity to list entropy; but, their discrimination was also affected by their memory for list items and by the accumulated evidence for a same versus a different response. Statistical models confirmed and quantified the importance of these additional factors.     

The emotional impact of faces (but not names): Face specific changes in skin conductance responses to familiar and unfamiliar people

Skin Conductance Responses (SCRs) to familiar and unfamiliar names and faces were recorded from independent groups of subjects, using two different presentation designs: the first employing fewer familiar than unfamiliar items (Tranel, Fowles, and Damasio, 1985) and the second employing equal numbers of familiar and unfamiliar items. In both designs, familiar faces were responded to significantly more strongly than unfamiliar faces, whereas for names there was no difference in responses to familiar and unfamiliar stimuli. Faces produced significantly larger overall SCRs than names in the unequal familiar/unfamiliar ratio design, but this effect was not observed in the equal ratio design. The results are discussed with particular reference to those previously published by Tranel et al. (1985) and in relation to work both on covert recognition in prosopagnosia and on one of the delusional misidentification syndromes known as the Capgras delusion. This study was carried out with generous support from the EJLB Foundation (Canada) and the Wellcome Trust.     

Structure and provision of services in Black churches in New Haven, Connecticut

Historically, Black (or African American) churches have played a central role as a center of religious and political life and also as a provider of human services and a healing community. This article examined the extent to which African American churches in 1 Northeastern urban environment are involved in the delivery of health and human service programs to their communities. It also explored how comfortable Black clergy are in referring their parishioners to the formal mental health system and identified the actual level of referrals. In addition, the analyses considered the individual and organizational characteristics that predict variations in the levels of support services and the likelihood of referral. Analyses revealed that African American churches deliver a broad range of services to the community. More than two thirds of the clergy feel comfortable in making a referral to a mental health agency or professional, and more than half have actually made a referral. Both service delivery and referral levels varied by several clergy and congregational characteristics. The implications of these findings for research and health policy are considered.     

Anorexic eating attitudes and behaviors of male and female college students

This study examined gender differences in eating attitudes and behaviors in a sample of 471 undergraduate college students. The prevalence of symptomatology indicative of anorexia was determined using the Eating Attitudes Test (EAT-26). In addition, the family climate, parent-child dynamics, and self-concept of students with and without maladaptive eating attitudes and behaviors were compared, and the relationship between eating attitudes/behaviors and current psychological distress was examined. Anorexic symptomatology was found for 20% of the females and 10% of the males. In general, students without symptomatic attitudes and behaviors had a more positive self-concept and reported less psychological distress than did those with eating disturbances. The findings suggest that eating problems may be more prevalent among males than previously estimated.     

Group psychotherapy treatment of borderline personalities.

Borderline personalities have been treated in psychotherapy groups for over 40 years. This article elaborates some of the characteristics pertinent to the treatment of these patients. Combined treatment of group and individual therapy addresses the needs for object constancy, the integration of object and self representations, and the possibility of attachment to others. Collaboration with individual therapists in this process is essential and there are specific conditions that allow this to occur as well as guidelines to help them make referrals. Cotherapy can be especially beneficial if the cotherapy team is knowledgeable and experienced. The group therapist must have special training and supervision to conduct groups of such intensity and affectively laden content.     

Understanding covert recognition

An implementation of Bruce and Young's (1986) functional model of face recognition is used to examine patterns of covert face recognition previously reported in a prosopagnosic patient, PH. Although PH is unable to recognize overly the faces of people known to him, he shows normal patterns of face processing when tested indirectly. A simple manipulation of one set of connections in the implemented model induces behaviour consistent with patterns of results from PH obtained in semantic priming and interference tasks. We compare this account with previous explanations of covert recognition and demonstrate that the implemented model provides the most natural and parsimonious account available. Two further patients are discussed who show deficits in person perception. The first (MS) is prosopagnosic but shows no covert recognition. The second (ME) is not prosopagnosic, but cannot access semantic information relating to familiar people. The model provides an account of recognition impairments which is sufficiently general also to be useful in describing these patients.     

Criterion-related validity of a new classification scheme for institutionalized mentally retarded individuals

Two studies were carried out to test the validity of a new three-cluster classification scheme. The association of cluster membership with both clients' movement and program placement was significant, but only in the case of the latter criterion was prediction improved by knowledge of a client's cluster membership.
