Improving multiple behaviors for colorectal cancer prevention among african american church members.

The WATCH (Wellness for African Americans Through Churches) Project was a randomized trial comparing the effectiveness of 2 strategies to promote colorectal cancer preventive behaviors among 587 African American members of 12 rural North Carolina churches. Using a 2 X 2 factorial research design, the authors compared a tailored print and video (TPV) intervention, consisting of 4 individually tailored newsletters and targeted videotapes, with a lay health advisor (LHA) intervention. Results showed that the TPV intervention significantly improved (p <.05) fruit and vegetable consumption (0.6 servings) and recreational physical activity (2.5 metabolic task equivalents per hour) and, among those 50 and older (n = 287), achieved a 15% increase in fecal occult blood testing screening (p =.08). The LHA intervention did not prove effective, possibly because of suboptimal reach and diffusion.     

Anorexia nervosa: the treatment of a male case with combined behavioural and family therapy

The successful treatment of a case of anorexia nervosa in a 14-year-old boy is described in this paper. The treatment comprised an initial month-long hospital-based behavioural weight gain programme. Concurrently a family evaluation was conducted. Family therapy, involving the parents only, was conducted over a subsequent four month period. The management of a relapse four months after the termination of treatment is described and information obtained at 9 and 16 month follow up is presented.     

Assessment of adult relatedness: a review of empirical findings from object relations and attachment theories

Assessment techniques designed to measure adult behavior and mental representation that emphasize relatedness constructs are reviewed. These measures grow out of two traditions, object relations and attachment theories. Although these two paradigms are fairly well elucidated theoretically, the relevant assessment literature is only more recently expanding, especially that focusing directly on adult attachment as opposed to childhood attachment. In addition to a presentation of various projective and objective measures, this review highlights the clinical and research implications for integration of these two paradigms around the cognitive, affective, and behavioral vicissitudes of adult relatedness.     

Semantic priming and repetition priming from masked words: evidence for a center-surround attentional mechanism in perceptual recognition

Two lexical decision experiments compared semantic and repetition priming by masked words. Experiment 1 established prime-mask stimulus onset asynchronies (SOAs) with presence-absence detection judgments. Primes presented at detection-threshold SOAs produced equal facilitation for repeated and semantically related targets: 26 ms and 24 ms. Experiment 2 established SOAs with semantic judgments. Primes presented at 70% of the semantic-threshold SOA to mimic the exposure conditions of Experiment 1 produced slightly greater facilitation for repeated targets but a tendency toward inhibition for semantically related targets: 38 ms and -6 ms. These results confirm Dagenbach, Carr, and Wilhelmsen's (1989) report that strategies induced by threshold-setting tasks can influence masked priming. In addition, Experiment 2 suggests a mechanism for retrieving weakly activated semantic codes into consciousness that relies on the center-surround principle to enhance activation of sought-for codes and to inhibit related codes stored nearby in the semantic network.     

A functional assessment of heterosocial initiation behaviors in adults

The present investigation was designed to assess the relationship between empirically defined behavioral strategies and ratings of social effectiveness, liking, and skill. Female subjects rated audiotapes of dyadic heterosocial interactions. The dyads' verbal behavior was manipulated experimentally such that each male actor exhibited one of two strategies, other-enhancement and positive self-presentation, and each female coactor exhibited one of two responses, encourages and discourages. After each audiotaped interaction, subjects rated each male on five questions: liking, continued interaction, effectiveness, social skill, and similarity. The results indicated that subjects distinguished between effective and ineffective strategies. The data obtained from all questions indicated that subjects preferred the male who was encouraged irrespective of what strategy he used. This study analyzed relevant variables within an interactional framework allowing for a functional, rather than topographic, analysis of social behavior. From this functional perspective, topographically different heterosocial initiation strategies may be viewed as appropriate or effective based on the reactions of the other person in the interaction.     

Target position and practice in the identification of letters in varying contexts: A word superiority effect

A forced-choice detection paradigm controlling for postperceptual inference was used to investigate letter identification in three-position displays. Letters from a predesignated set of four targets appeared singly, in strings of noise characters, in unpronounceable nonsense strings, and in words. Subjects knew which context would occur, but did not know which of the three display positions would contain the target. Correct detection data were collected at constant exposure duration over five testing sessions. Overall identification accuracy was higher in words than in all other contexts, the first word superiority effect to be found with targets specified in advance since Reicher’s (1969). This effect remained constant over sessions. An interaction between context type and target position showed enhanced accuracy for initial and terminal letters in words, but depressed accuracy at initial and terminal positions in other contexts. This was interpreted to mean that prior knowledge of context is used to alter the dynamics of perceptual analysis.
