توزیع شخصیت و تراکم رفتار، احساسات و موقعیت

Whole Trait Theory defines personality as a density distribution of one’s momentary behavior, complete with all of its parameters (e.g., mean, SD, skew, kurtosis). Two questions regarding these parameters remain largely unexamined: (1) are individual differences in these parameters stable? And (2) do scores on standard personality tests correspond to these parameters? The current study (N = 209) employed an experience sampling design (Nobs ≈ 8300) to examine the stability of density distribution parameters and the relationship between standard personality test scores and density distribution parameters of 10 behaviors/emotions and 8 situation characteristics. Results showed that, (a) individual differences in density distribution parameters are moderately stable and (b) at the bivariate level, personality was associated with numerous distribution parameters for a number of behaviors/emotions, and situations. However, when the appropriate statistical controls were taken into account, these associations diminished. While individual differences in density distribution parameters we moderately stable, standard personality measures rarely correspond to any other parameters of density distributions once the mean of the density distribution is known. Emotionality and eXtraversion appear as exceptions to this general pattern. These results imply that both theory and measurement in personality should be cognizant of within-person variability in behavior.
