Students prefer the immediate feedback assessment technique.

Students responded to a questionnaire after completing classroom examinations using either Scantron forms or the Immediate Feedback Assessment Technique. Factor analysis of students' responses yielded six scales unrelated to students' grades and not differing by sex, course, or instructor. Students evaluated on the latter technique scored significantly higher on scales measuring ease of understanding and ease of completing response requirements, perceived fairness of and preference for an answer-until-correct procedure, and enhanced involvement in the test-taking process.

Influences of early thyroid hormone manipulations: delays in pup motor and exploratory behavior are evident in adult operant performance.

The effects of thyroid hormone depletion and enhancement on litter size, survival, body mass, ambulation, quadrant crossing, home orientation, day of eye opening, and free serum T3 and T4 levels were examined in Study 1. In Study 2, the effects of the timing of prenatal insult and the level of thyroid hormone depletion on litter size, survival, body mass, and free serum T3 and T4 levels were examined. Upon the completion of Study 1, randomly selected pups were maintained on ad-libitum water and food for 2 years, and performance was evaluated on fixed and variable ratio schedules, fixed and variable interval schedules, and probability and reversal learning tasks (Study 3).

Immediate Feedback Assessment Technique: multiple-choice test that "behaves" like an essay examination.

A multiple-choice testing system that provides immediate affirming or corrective feedback and permits allocation of partial credit for proximate knowledge is suggested as an alternative to essay examinations.

Age-related susceptibility to the Müller-Lyer and the horizontal-vertical illusions.

Participants between the ages of 3 and 20 years adjusted the Müller-Lyer illusion and the inverted-T form of the Horizontal-Vertical illusion. Perceptual error was quantified using signal detection and nonparametric measures of sensitivity and responsivity. Significant changes in sensitivity and responsivity were found for each illusion across participants' ages.

Immediate feedback during academic testing.

Performance on two multiple-choice testing procedures was examined during unit tests and a final examination. The Immediate Feedback Assessment Technique provided immediate response feedback in an answer-until-correct style of responding. The testing format which served as a point of comparison was the Scantron form.
