title: Data from: Are extraversion and openness indicators of a slow life history strategy?

description: Theory and data generally concur that a slower Life History Strategy (LHS)
 is associated with higher Conscientiousness, Agreeableness and Emotional
 Stability. Whether Extraversion and Openness are indicators of a slow LH,
 or whether they include both fast and slow LH components, remains
 unresolved. I addressed these questions in two studies: one of university
 students observed via periodic brief audio recordings during 72 hours of
 their daily lives, and the second a re-analysis of data from Block and
 Block’s (2006) longitudinal study. In both studies, I operationalized LHS
 as the correlation between an individual’s California Q-Sort (CAQ) profile
 and the slow Life History (SLH) CAQ template created by Sherman et al.
 (2013) and Dunkel et al. (2015). I calculated Five Factor Model dimension
 scores using McCrae et al’s (1986) method. In both samples, individuals
 whose CAQ profile more closely resembled the SLH template were higher in
 Conscientiousness, Agreeableness, and Emotional Stability than those
 pursuing a faster LHS. Extraversion was unrelated to LHS, while Openness
 in the Block and Block data set was actually associated with a faster LHS.
 Analysis of individual CAQ items revealed some differences between the
 studies. Generally, Extraversion-loading items tapping excitement-seeking
 and self-dramatization, and Openness-loading items tapping nonconformity,
 were associated with a faster LHS. Participants in the audio recording
 study also completed a HEXACO personality inventory and the Arizona Life
 History Battery. LHS as measured by the ALHB was uncorrelated with LHS as
 measured by the CAQ. Controlling for Extraversion yielded a significant
 positive relationship between the two LHS measures, suggesting that their
 poor convergent validity resulted from differences in their coverage of
 Extraversion-related content.
description: Manson_Extraversion-Openness-LHS_dataParticipants: 93 UCLA students. Procedure: Ps wore the Electronically Activated Recorder for 72 hours, generating one 30-sec audio recording every 12.5 min from 0600-2400. Ps also kept an hour-by-hour event diary. Based on the audio clips and event diaries, research assistants described Ps' personalities using the California Adult Q-sort (CAQ). Column R contains the correlation (r-to-z transformed) of each P's CAQ profile with the Slow Life History CAQ template. Columns S-X contain the CAQ-profile-based scores on each FFM model dimension (neuroticism, extraversion, openness, agreeableness, and conscientiousness), based on McCrae et al (1986). Column V contains the openness scores after improving inter-item reliability by dropping CAQ items 007, 041, and 062. After the audio sampling phase of the study, Ps completed the Arizona Life History Battery (column C contains the overall K-factor, the mean of the standardized scale scores excluding the mini-K) and the HEXACO-60 (columns D-I contain standardized scores of the major HEXACO dimensions, while columns J-Q contain the standardized scores of the four Extraversion facet scales and the four Openness facet scales).
