Frequency, phase, and colour coding in apparent motion: 2

In an earlier paper, Caelli and Finlay demonstrated that the perception of apparent motion was contingent on critical phase relationships between inducing sources, and their spatio-temporal frequency ranges. In their original stimulus red-green centre-surround sources were used and phase-specific inhibition was found at 60 degrees--90 degreee phase angle differences between the complementarily coloured elements. In this experiment we show that, when centre-surround sources are replaced by vertically-horizontally displaced complementary (or identically coloured) sources, symmetrical phase inhibition effects occur with both motions.

Predicting Exercise and Health Behavioral Intentions: Attitudes,Subjective Norms,and Other Behavioral Determinants1

By comparing exercise and health domains, the current experiment extends recent findings that within‐participant analyses of attitudes and subjective norms predict behavioral intentions well (Finlay, Trafimow, & Moroi, 1999). Within‐participant analyses show that health behaviors are particularly likely to be influenced by subjective norms, and those that are relatively normatively influenced are intended to be performed more than those that are not. However, neither was true of exercise behaviors. Additionally, other potential predictors for exercise (e.g., indirect attitudinal measures and goal‐oriented attitudes and intentions) correlated more strongly with exercise behavioral intentions than did general health attitudes and intentions.     

Identifying support systems: a mapping exercise

Within systemic training there is an increasing focus on integrating trainees' personal life experiences and beliefs with their practice. In this paper we present a mapping exercise that is used to help trainees explore their own support needs and the resources they draw upon in order to carry out their work. Although this exercise was developed from training carried out with professionals working with refugees it is our belief that it can be used by any professional groups who wish to explore their own support needs within a learning environment.     

Methodological issues in interviewing and using self-report questionnaires with people with mental retardation

In this article the authors review methodological issues that arise when interviews and self-report questionnaires are used with people with mental retardation and offer suggestions for overcoming some of the difficulties described. Examples are drawn from studies that use qualitative methodology, quantitative studies assessing different question types, and studies reporting on the development of instruments measuring psychiatric symptoms, self-concept, and quality of life. Specific problems that arise with respect to item content (e.g., quantitative judgments, generalizations), question phrasing (e.g., modifiers), response format (e.g., acquiescence, multiple-choice questions), and psychometric properties (factor structure and validity) are discussed. It is argued that because many self-report questionnaires include questions that have been found to be problematic in this population, more attention needs to be paid to establishing the validity of such measures and to clearly defining the population for which the instrument is designed.
