Phlebotomist interpersonal skill predicts a reduction in reactions among volunteer blood donors.

BACKGROUND: Adverse reactions in response to blood donation negatively affect the likelihood of donor return. In this study, the interpersonal skill of phlebotomists was examined as a potential predictor of both donor reactions and returns for future donation. STUDY DESIGN AND METHODS: Participants were 82 phlebotomists who completed the Social Skills Inventory, a global measure of interpersonal skill. Scores on this measure were used to predict the likelihood of donor reaction (rated by phlebotomists) and return for future donation in two samples of volunteer blood donors associated with these phlebotomists. Use of two samples permitted examination of phlebotomist interpersonal skill as a predictor of donor reactions and returns both before and after the phlebotomists were aware of the interpersonal skills assessment. RESULTS: Results of multilevel logistic regression analyses demonstrated that a one-standard-deviation increase in Social Skills Inventory score was associated with a significant reduction in the likelihood of donor reaction in the first sample (odds ratio [OR], 0.86; 95% confidence interval [CI], 0.76-0.96) and with a marginally significant reduction in the likelihood of donor reaction in the second sample (OR, 0.90; 95% CI, 0.79-1.02). Social Skills Inventory scores were not related to returns for future donation in either sample. CONCLUSIONS: This study provides the first empirical evidence that phlebotomist interpersonal skill predicts the experience of reactions among volunteer blood donors. A focus on the interpersonal skill of phlebotomists may therefore provide an additional avenue for improving donors' physical well-being and satisfaction, thereby enhancing donor retention.

Testing different interpretations for the mistaken belief that rays exit the eyes during vision.

Research has shown that children and adults believe that emissions from the eye occur during the act of vision. Such beliefs are similar to ancient extramission theories of perception. In Study 1, the authors tested the idea that extramission beliefs might stem from people's thinking about what might occur during vision as opposed to what is necessary for seeing. Training participants to think about what is necessary for vision, however, had no effect on extramission responses. The results of Study 2 indicated that emphasizing the idea of visual input led to a decline in extramission responses and supported the hypothesis that extramission notions stem from the outer-oriented phenomenology of vision.

Processing of logically valid and logically invalid conditional inferences in discourse comprehension.

Two competing theories of processing of conditionals (if-then) were tested. Syntactic theories posit that people only draw inferences conforming to the logically valid modus ponens (MP) schema. Mental models theories predict that people draw MP and invalid affirming-the-consequent (AC) inferences. Three experiments tested these predictions. Participants read short stories that conformed to either the MP or AC form but without conclusions, and they completed either priming or recognition tasks. Results indicate that both MP and AC inferences occur during discourse processing: MP and AC premise forms prime their respective conclusions, participants erroneously judged that they had read the conclusions to MP and AC arguments, and AC inferences did not stem from a biconditional interpretation of conditionals. Findings support mental models theories.
