[email protected]. INDIVIDUAL DIFFERENCES IN TIMING MEASURES: CONTINUATION TAPPING, RELAXATION TIME, REACTION TIME, AND CRITICAL FLICKER FUSION. BY ANNAS. KLEVAK A DISSERTATION SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY IN PSYCHOLOGY UNIVERSITY OF RHODE ISLAND 1997 ABSTRACT In order to investigate human time sense individual differences in timing were studied in a sample of 39 healthy adults at rest. Fast Muscular Relaxation Time, Preferred Muscular Relaxation Time, Critical Flicker Fusion Threshold, Continuation Tapping, and Simple and Choice Reaction Times were examined with the aim of determining both linear and non-linear relationships among the measures. Several significant linear relationships among the variables were obtained. Subjects with higher Critical Flicker Fusion threshold exhibited significantly less overall variability in timing, (p<0. 001) and showed a slower increase in variability with increasing interstimulus interval. The Simple Reaction Time was positively correlated with the Fast Relaxation time (p<0.05).
