Differences in the technical and applied nutrition knowledge of older adults.

Although elder adults are much more knowledgeable about nutrition than ever before, diet behavior is not consistent with nutrition knowledge. One of the reasons for this inconsistency may be that the ability to apply technical nutrition knowledge is still inadequate. To test the hypothesis that technical nutrition knowledge is superior to applied nutrition knowledge, 96 volunteer seniors were given technical nutrition knowledge tests associated with heart disease, cancer, and high blood pressure. After the technical knowledge tests, subjects were asked to choose from among pairs the item that contained: (a) cholesterol, (b) more saturated fat, (c) more polyunsaturated fat, (d) substances that help to lower blood cholesterol, (e) more fiber, and (f) less sodium. Results support the notion that, in general, elder ability to apply nutrition knowledge is not as adequate as their technical nutrition knowledge.

Guidelines for measuring reaction time.

Although reaction time is one of the most common measures of neurological function, protocols often do not take into consideration many of the extraneous factors that may invalidate such assessments. This paper discusses several issues related to matters of instrumentation, subject control, design of assessment, and interpretation. Twenty recommendations are provided as a guideline for those who assess reaction time of clients or patients. While these suggestions are not proposed as definitive or complete, the points should serve as a guide to young researchers as well as a checklist for more seasoned experimenters.

Reconsideration of measurement of error in human motor learning.

Human motor learning is often measured by error scores. The convention of using mean absolute error, mean constant error, and variable error shows lack of desirable parsimony and interpretability. This paper provides the background of error measurement and states criticisms of conventional methodology. A parsimonious model of error analysis is provided, along with operationalized interpretations and implications for motor learning. Teaching, interpreting, and using error scores in research may be simplified and facilitated with the model.
