Effects of personality, perceptual difficulty and pacing of a task on productivity, job satisfaction, and physiological stress.

The relative psychological, physiological, and performance advantages and disadvantages of utilizing machine-paced and self-paced work were examined by having 12 subjects perform a marking-stapling task at 2 levels of perceptual difficulty and under 2 pacing conditions for 30 min. each. (a) 3 subjects who on the personality tests were identified as introverted, reserved, and trusting preferred to work in the machine-paced condition, while 9 subjects who were identified as extroverted, outgoing and suspicious preferred the self-paced condition, (b) the performance errors in machine-paced operation were 372% higher than for self-paced work, and (c) there were no differences between machine-paced and self-paced work on physiological variables, except for sinus arrhythmia for the task with high perceptual load, and quantity of production.

Improving evaluation of amalgam restorations.

A predictive model of overall quality of performance is presented which might assist both dental students and dental faculty by increasing the reliability of clinical and laboratory evaluations. Training effectiveness can be improved by identification of those restorative skills which contribute most to the quality rating of restoration.

Perceptual and motor training for the acquisition and retention of psychomotor skills in dental amalgam restorations: class I in the mandibular first molar.

From a study of 72 dental students during amalgam restoration using four training methods (psychomotor, mental, psychomotor and mental, and conventional)--one method for each 18 students--the following conclusions are drawn: (1) It is economically feasible to develop and utilize self-paced instructions without the aid of instructors for the acquisition of psychomotor skills. (2) Training through self-paced analytical programs results in higher retention of the acquired skills than training through conventional training methods.

Skills analysis of a class I amalgam restoration in a mandibular right first molar.

1. Students changed their body position 32% more often than instructors during amalgam condensation. 2. Experienced instructors used 38% fewer strokes than students to condense the amalgam. 3. On the average, instructors used 65% less time per condensation stroke than students. This was not due to ability to move the instrument more quickly, since both students and instructors had similar minimum stroke times, but rather to the fact that instructors performed slowly less often. 4. The upstroke during condensation required nearly the same time for both students and instructors (an eight percent difference). It was the downstroke that was greatly different (a 96% difference). 5. Instructors repeated condensation strokes 22% more often than students, working more systematically with less "jumping around" in the cavity. 6. The total number of carving strokes was not related to experience. 7. Students repeated carving strokes more often than instructors. 8. Students and instructors tended to use the same length of strokes in carving. 9. There was a noticeable difference between instructors and students in the method used to grasp the instruments.

Objective evaluation of quality in cavity preparations.

Significant improvements in reliability of criteria measures were obtained by using a newly developed instrument to evaluate objectively the quality of cavity preparations in comparison to subjective ratings by the instructors of the quality of cavity preparations.
