An indigenous community mental health service on the Tohono O'odham (Papago) Indian reservation: Seventeen years later

The status of a fully indigenous mental health program serviced and controlled by the Tohono O'odham (Papago) Indian tribe is reviewed from the perspective of its 17-year history. The program functions in large measure in a crisis intervention model, with suicidal or acutely disturbed cases being most frequent. However, a whole range of disorders and ages are seen. Traditional Medicine Men and Women are often used as consultants, as are some professionals. In recent years child sex abuse and abuse of drugs among youth are prominent problems. The program experienced problems of obtaining services off reservations for patients in need, and in establishing credibility of the Indian Mental Health workers with the outside service providers.     

Oysters, rabbits and people: A critique of “race differences in behaviour” by J.P. Rushton

Rushton's article is criticized for its logic, the credibility of some of its sources, selectivity from the literature and from data within studies, failing to consider diversity in subgroups within races that may exceed differences between races, lack of analysis of racial differences in socioeconomic status and how this might influence group differences, and failure to apply statistical tests to minute differences between means. A wide range of phenomena assumed to be heritable are linked with the idea that they serve a reproductive end. However, there is no evidence that fertility itself is heritable. Large scale studies have shown no racial differences in diagnoses or on the MMPI that fit Rushton's theory. Rushton's analysis of international data on the EPQ is selective, ignoring the variance within racial groups and the scale of greatest relevance for his theory: P. An analysis of the data on this scale reveals no results in conformance with his theory. Data on sexual behavior is based on small and unrepresentative samples of blacks. Sizes of heads and genitals are compared with no obvious connection to the primary issue of biological fertility strategies. Everything is assumed to be on a primarily genetic basis although sexual mores have shown remarkable changes in a single generation.     

A titration procedure for generating escape behavior

In a grid-shock escape paradigm using time-out as reinforcement, both fixed-ratio and variable-interval performances were established directly from a continuous reinforcement schedule with rats and guinea pigs. A procedure was developed that employed a stepwise decrease in reinforcement time for all responses except the terminal response. Acquisition and long-term maintenance data were obtained from Ss trained on this titrated negative-reinforcement procedure.     

The role of spatial frequency in the processing of hierarchically organized stimuli

Can spatial frequency differences between local and global forms account for differences in the way different levels of structure are analyzed? We examined this question by having subjects identify local or global forms of hierarchical stimuli that had beencontrast balanced. Contrast balancing eliminates low spatial frequencies, so that both local and global forms must be identified on the basis of high spatial frequency information. Response times (RTs) to global (but not local) forms were slowed for contrast-balanced stimuli, suggesting that low spatial frequencies mediate the global RT advantage typically found. In contrast, interference between local and global forms was little affected by contrast balancing or by shifts of attention between local and global forms, suggesting that it does not result from inhibitory interactions between spatial frequency channels or from temporal precedence of low versus high spatial frequency information. Finally, shifts of attention between local and global forms were also little affected by contrast balancing, suggesting that they were not based on spatial frequency.     

The Psychophysiology of Sensation Seeking

This article summarizes studies relating the trait of sensation seeking to electrodermal and heart-rate responses and cortical evoked potential arousal. Stimulus factors of novelty, intensity, and stimulus significance are important. High sensation seekers tend to give stronger physiological orienting responses than lows to novel stimuli of moderate intensity, particularly when such stimuli are of specific interest. Lows tend to show defensive responses as defined by heart-rate acceleration. The cortical reaction of the highs tends to be augmented by intense visual or auditory stimuli, while that of the lows tends to be reduced or unresponsive to variations in stimulus intensity. Differences between psychophysiological responses of high and low sensation seekers are interpreted as reflective of different evolved biological strategies for processing novel or intense stimulation.     

SEEING TWO AS ONE:

Abstract -Object tokens are episodic visual representations that mediate the ability to track visual events as they move about and change over time. Multiple tokens also allow the viewer to individuate multiple instances of a single type of object. In the present study, we established a functional link for object tokens in two seemingly disparate visual phenomena: apparent motion and repetition blindness [RB]. In RB, repeated items are more difficult to perceive than unre-peated items. Using displays in which two sets of alphanumeric characters streamed in opposite directions across a computer screen in apparent motion, we found increased RB for targets appearing within a single apparent motion stream, relative to targets in different apparent motion streams. The results are inconsistent with refractory period or memory retrieval accounts of RB and support the role of object tokens in both apparent motion and RB.     

Process characteristics of worry and obsessive intrusive thoughts

One hundred and twenty-five university students were administered a battery of self-report measures to assess worry disposition and content, frequency of obsessive intrusive thoughts, and 10 conceptually derived appraisal dimensions of worry and obsessional intrusions. Process ratings indicated that the worrisome thoughts were considered more disturbing than the ego-dystonic intrusive thoughts. Worry was also distinguished by a focus on the possible consequences of negative events, whereas concern about the personal meaning of the thought was a unique process dimension for obsessive intrusive thoughts. Both content and process variables are important in differentiating worry and obsessive-like intrusive thoughts in a nonclinical population.     

On seeing oneself as “left out”: The chronically complaining patient in psychotherapy

A clinical observation regarding patients who complain about feeling left out and/or second best provides the framework for this paper. What is expressed is a form of separation anxiety coupled with a loser self-concept. It is suggested that these patients represent a milder form of the moral masochism. Early theoretical formulations include Freud and his emphasis on the superego and Reich's emphasis on the masochist's fear of being left alone. Kramer's little man phenomenon is an example of a more current theoretical formulation which takes account of the complexities of the ego, and composite self and identity in the clinical phenomena observed. A case of a latency-aged child is provided.
