| Abstract: | This article introduces a new method for assessing personality traits that uses graphic rather than written items to facilitate the convergent validation of personality traits. A computer-administered visual analog procedure is presented that samples 40 equally spaced positions along a trait continuum five times. Examinees initiate each trial by pressing the space bar and end it by pressing either a “True” or “False” key indicating if that location describes them or not. Response time is measured in milliseconds. The majority answer determines the aggregate response and the median response time determines the latency for the aggregate response to each location on the trait continuum. This procedure enables an empirical measure of trait variability. Results indicated theoretically meaningful responses in 94 college students on each of two personality dimensions; extraversion and trait anxiety. The predicted inverted-U function was obtained for both personality dimensions such that the fastest response times were associated with 0 and 5 “True” responses, somewhat longer response times were associated with 1 and 4 “True” responses, and the longest times were associated with 2 or 3 “True” responses. Statistically significant and substantial validity coefficients were obtained with the Eysenck personality inventory extraversion scale, and the state-trait anxiety inventory, form Y-2. |
