Identification and ratings of caricatures: Implications for mental representations of faces

S. Brennan (1985, Leonardo, 18, 170–178) has developed a computer-implemented caricature generator based on a holistic theory of caricature. A face is represented by 37 lines, based on a fixed set of 169 points. Caricatures are produced by exaggerating all metric differences between a face and a norm. Anticaricatures can be created by reducing all the differences between a face and a norm. Caricatures of familiar faces were identified more quickly than veridical line drawings, which were identified more quickly than anticaricatures. There was no difference in identification accuracy for the three types of representation. The best likeness was considered to be a caricature. We discuss the implications of these results for how faces are mentally represented. The results are consistent with a holistic theory of encoding in which distinctive aspects of a face are represented by comparison with a norm. We suggest that this theory may be appropriate for classes of visual stimuli, other than faces, whose members share a configuration definable by a fixed set of points.     

Use of Legal Drugs by Psychiatric Outpatients: Benefits, Costs, and Change

Caffeine, nicotine, and alcohol use by persons with a severe mental illness occurs frequently but is poorly understood. We used qualitative methods to elicit information regarding the functional relationships between legal substance use and its antecedents and consequences. This report summarizes responses provided by 37 psychiatric outpatients who participated in focus groups and key informant interviews regarding the use and functions of alcohol, caffeine, and nicotine. We describe major themes regarding positive and negative consequences, triggers for use, change efforts, and offer observations regarding substance use in this under-served population.     

Patients taking the lead. A naturalistic investigation of a patient led approach to treatment in primary care

In an earlier paper (Carey, T. A. (2005). Can patients specify treatment parameters? A preliminary investigation. Clinical Psychology and Psychotherapy, 12, 326–335) an approach to treatment delivery was examined in which the duration and frequency of the appointments was scheduled by patients. Results of this approach were encouraging but the generalizability of the results was constrained because only one clinician trialed the approach and no standardized assessment measures were used. In the present study there are two clinicians involved and the Depression Anxiety Stress Scale (DASS) was used. The approach was introduced at one GP practice and monitored over a six-month period. Results suggest that this approach might be an effective way of promoting patient access to, and involvement in, service delivery as well as reducing waiting times.     

Précis of 'The Origin of Concepts'

A theory of conceptual development must specify the innate representational primitives, must characterize the ways in which the initial state differs from the adult state, and must characterize the processes through which one is transformed into the other. The Origin of Concepts (henceforth TOOC) defends three theses. With respect to the initial state, the innate stock of primitives is not limited to sensory, perceptual, or sensorimotor representations; rather, there are also innate conceptual representations. With respect to developmental change, conceptual development consists of episodes of qualitative change, resulting in systems of representation that are more powerful than, and sometimes incommensurable with, those from which they are built. With respect to a learning mechanism that achieves conceptual discontinuity, I offer Quinian bootstrapping. TOOC concludes with a discussion of how an understanding of conceptual development constrains a theory of concepts.

Children's Use of Gaze and Limb Movement Cues to Infer Deception

A sample of 96 children from kindergarten, 2nd, 4th, and 6th grades judged the truthfulness of peers who varied in gaze and limb movement while providing verbal communications. Results indicated that children attributed greater lying to the peers who displayed indirect rather than direct gaze and active rather than nonactive limb movement. The use of these cues was more evident in 4th- and 6th-grade children than it was in kindergarten and 2nd-grade children. Pilot studies indicated that adults and children as young as 5-6 years of age associated indirect gaze and active limb movement with anxiety. The findings are discussed with respect to children's theory of mind, concepts of lying, understanding of display rules, and learning of physiological cues associated with deception.
