Two Generalizations of the Item Discrimination Index to Multi-Score Items
The Journal of Experimental Education, 1971Two general item analysis indices which apply to multi-score items are developed as generalizations of a popular index applicable to dichotomous items.

The American Journal of Psychology, 1981
Experiment 1 examined the relationship between item retrievability and item discriminability using a generate-rate task. All the items of an input list came from a single category first names. The generate-rate task required subjects to generate, over a 10-min period, as many first names as possible and to rate each name for list membership ...

Convergent and Discriminant Validity in Item Analysis
Educational and Psychological Measurement, 1978Described is an alternative algorithm for item analysis in which item discrimination indices have been defined for item distractors in addition to their traditional definition for the scored alternative. Also, the Campbell and Fiske concept of convergent and discriminant validity was reconceptualized from the test to the item level and proposed as an ...

Discrimination of the Target Item and the Reduction of Interference
The American Journal of Psychology, 1976When subjects learned paired associates that, on the study trials, consisted of a stimulus (cue) and its correct (target) response plus two other (distractor) responses from within the list, the presence of the distractor items interfered with learning, especially when overtly pronounced as opposed to silently studied.

Development of a 15-Item Odour Discrimination Test (Düsseldorf Odour Discrimination Test)
Perception, 2012A key function of the olfactory system is the detection of differences in odour quality. Therefore, a test was developed to assess odour discrimination ability in normosmic humans. Out of six monomolecular substances (capric acid, coumarin, eugenol, geraniol, phenylethyl alcohol, and vanillin) quaternary mixtures were prepared.

SIMILARITY OF VARIOUS ITEM DISCRIMINATION INDICES
Journal of Educational Measurement, 1976Although certain methods of determining item discrimination appear to be used more frequently than others, measurement specialists fail to agree as to which method is most appropriate. For example, Guilford (1965) and Nunnally (1967) argued in favor of the point-biserial r on the basis that it tells more about the contribution of a particular item to ...

Psychological Reports, 1987
The effects of stem orientation (positively stated stem or negatively stated) and completeness (closed or complete stem and incomplete stem) of multiple-choice items on difficulty and discrimination, were studied experimentally employing 142 senior students in education (82 women and 60 men).
