Based on ratings of 30 emotions on 50 adjective scales, secured from 117 university students, factor analysis yielded 3 dimensions of emotion, phenomenologically characterized as pleasantness vs unpleasantness, activation, depth. Operational characterization resulted from the correlations of the dimensions with personality measures: pleasantness vs unpleasantness converged with extraversion vs introversion, ego strength vs ego weakness, field independence vs field embeddedness, activation converged with impulsivity and cognitive simplicity. Depth was associated with enhanced self-evaluation.
