A new approach to the generation of visual stimuli for eye-movement research

An interactive, computer-controlled, visual stimulus generator is described, suitable for both psychophysical and neurophysiological experimentation on human subjects. The system core is a wide-screen electrostatic cathode-ray tube, which can be used both as a television monitor, to display standard video pictures, and as anx-y oscilloscope, so that a bright dot can be moved around the display by electrical signals. In addition, a third working mode is provided, according to which a time-compressed video picture of limited size (fast picture) plays the role that is typical of the spot in a standard oscilloscope. Through computer-assisted time compression, the frame period of the video signal is reduced to about one tenth of its standard value. The fast picture can accordingly be driven by even the fastest eye movements, and it can be displayed as a stabilized image, or, more generally, in the altered retinal feedback condition. Moreover, as compared with a standard video picture, the fast image can be “flashed” over much shorter time periods. Since a standard input video signal is used for both standard and fast video pictures, all the image processing facilities of commercial videographic systems can be fully exploited by the proposed device.     

Short-term psychodynamic intervention in an urban health clinic: A case report

This paper describes the application of short-term dynamic therapeutic techniques to treat both symptom disturbance and character pathology in an urban mental health clinic. Short-Term dynamic psychotherapy focuses extensively on the subjectivity and inner life of the patient with emphasis on repressed anger, sadness and desire. Methods to overcome patient ambivalence and resistance to psychotherapy are presented. The clinical psychodynamics associated with early life trauma are illustrated with a case of an African-American patient.Acknowledgments for support & critical feedback are expressed to Christine Baker, Ph.D., John Swanson, ACSW, Duncan Walton, Ph.D., and Isabelle Beveridge (Graphics).     

Mental image reversal and verbal recoding: When ducks become rabbits

A recent debate has concerned whether classical bistable configurations (e.g., duck/rabbit) can be reinterpreted using mental imagery. Research in this field indicates that image reversal is possible only when subjects change their specification of orientation. In a series of four experiments, we demonstrate that mental reversal of classical bistable configurations( CBCs) is impeded by verbally recoding the visual pattern at the time of input. When subjects were prevented from verbally recoding visual stimuli in short-term memory, they fared systematically better in mentally reversing the CBC, even when they received no instructions to change their reference frame or specification of orientation. On this basis, we suggest a model of image reversal that takes into account the interaction between memory codes and provides a new perspective on verbal recoding, verbal overshadowing, and mental discoveries.     

Variations on incremental interpretation

The strict competence hypothesis has sparked a small dialogue among several researchers attempting to understand its ramifications for human sentence processing and incremental interpretation in particular. In this paper, we review the dialogue, reconstructing the arguments in an attempt to make them more uniform and crisp, and provide our own analyses of certain of the issues that arise. We argue that strict competence, because it requires a synchronous computation mechanism, may actually lead to more complex, rather than simpler, models of incremental interpretation. Asynchronous computation, which is arguably both psychologically more plausible and conceptually more basic, allows for incremental interpretation to fall out naturally, without additional machinery for interpreting partial constituents. We show that this is true regardless of whether the presumed interpretation mechanism is top-down or bottom-up, contra previous conclusions in the literature, and propose a particular implementation of some of these ideas using a novel representation based on tree-adjoining grammars.The research in this paper was supported in part by grant IRI-9157996 from the National Science Foundation to the first author.

Good Practice in Transcultural Counselling: An Asian Perspective

In Britain today, counsellors and therapists often work with people from a diverse range of ethnic groups whose cultures are substantially different from their own. There is increasing concern that people from black and ethnic communities have limited access to appropriate services—despite service planners' and providers' statements that mental health services are being restructured to become more sensitive, relevant and meaningful to these communities. This paper is an attempt to redress the balance with an emphasis on the therapeutic needs of South Asian communities. It aims to challenge assumptions and beliefs held by therapists and counsellors, question therapeutic practice based within a white, middle-class ideology, raise awareness of an 'Asian' perspective in therapy, and provide some guidelines for good practice in transcultural counselling.     

Contributors to the Appraisal of Major Life Changes: Gender, Perceived Controllability, Sensation Seeking, Strain, and Social Support

This study investigated relationships between the appraisal of life events and gender, locus of control, social support, strain, and sensation seeking. In group sessions, undergraduate males and females completed self-report measures assessing life events appraisals and self-report measures for the above individual differences. Analyses supported the notion that a range of these variables, previously shown to serve as moderators of life stress, are significantly related to the appraisals of life events. Moreover, in addition to the gender differences obtained for the perception of life events, gender was found to influence several associations between the individual differences and life events appraisal.     

Disordered eating in women of color

It has been assumed that the occurrence of eating disorders in American racial minority groups are rare. Indeed, whereas the cultural context may afford “protection” to the group, it does not necessarily protect specific individuals. Individuals within each racial/ethnic group are subject to the standards of the dominant culture, particularly when the culture-of-origin is devalued by the dominant culture. Social, familial, and individual factors which contribute to disorders eating symptomatology are discussed. Discussions of obstacles to detecting eating disorders and guidelines for developing more inclusive theory of and treatment of persons with eating disorders is included.
