title: Repeatability of measures of biobehavioral organization over two years in captive infant rhesus macaques, Macaca mulatta

description: Individual differences of infant temperament have been associated with
 future health outcomes that provide explanatory power beyond adult
 personality. Despite the importance of such a metric, our developmental
 understanding of personality-like traits is poor. Therefore, we examined
 whether young primates show consistency in personality traits throughout
 development. We replicated a Biobehavioral Assessment (BBA) at three time
 periods: 3-4 months, one year, and two years of age in 47 rhesus macaque
 (Macaca mulatta) subjects from large mixed-sex outdoor social housing
 units at the California National Primate Research Center. We report
 results for tests focused on responses and adaptation to the temporary
 separation and relocation, responses to a threatening stimulus, and
 ratings of overall temperament. We found consistently repeatable
 associations in measures of Emotionality; these associations were stronger
 in males, but also present in females, and broadly consistent between year
 one and two. We also explored whether behavioral responses to this
 experimental relocation might be influenced by their experience being
 relocated for other reasons (i.e., hospitalizations) as individuals’
 responses might be influenced by similar experiences to the BBA procedure.
 Only locomotion, during one of the assessments, was associated with past
 hospitalization events. Overall, repeatability in Emotionality-associated
 behaviors was evident across the two years, in both sexes. We did,
 however, find evidence of the emergence of sex differences via
 differentiated expression of behavioral responses during the BBA. We
 emphasize that there is likely contextual nuance in the use of these BBA
 factor-associated behaviors. Further research is required to determine
 whether and how shifts occur in underlying factor structure and the
 expression of associated behaviors.
description: These data were collected from three tests utilized in the
 Biobehavioral Assessment program, at the California National Primate
 Research Center. Raw video codings have been cleaned and processed to a
 format standard for BBA analyses - as described elsewhere (Golub et al.,
 2009; Gottlieb & Capitanio, 2013).

 Pritchard, John P. Capitanio, Laura Del Rosso, Brenda McCowan, Jessica
 Vandeleest --- We have included 5 data files and one R code file. The R
 code functions to read in the files and assembles tables that were used to
 generate the table in the manuscript. ## Description of the data and file
 structure That is, comparing BBA factor scores (with long all CAPS columns
 names in TempeRates, HC1, HC2, HIT) to the BBA-associated behaviors from
 year one or two (column name Y); comparing BBA-associated behaviors
 between year one and two; and comparing BBA-associated behaviors to
 hospitalization events (Hosps). Data files are presented as csv files with
 the \_BBAVars suffix and are associated to the relevant BBA test (HC# for
 holding cage observations; HIT for human intruder observations; TempeRates
 for temperament ratings) and hospitalization events (Hosps). All data
 files include sex of the subject and sequentially ordered ID numbers to
 facilitate analyses. BBA-associated behaviors have the suffix P or R
 contingent on whether it is a rate or proportion. The five datafiles, and
 details about column/data structure, are as follows: **HC1_BBAVars:** data
 from observations of the subject animal in the holding cage during day 1
 of the BBA events on year 1 or year 2. animid = unique identifier for each
 subject animal Y = year of BBA event sampling (1 or 2) HAP1 - VCR1 = rates
 (R suffix) or proportions (P suffix) for the relevant behaviors as
 detailed in the primary open access manuscript DAY1ACTIVITY = Infant BBA
 scores for the factor of Activity DAY1EMOTIONALITY = Infant BBA scores for
 the factor of Emotionality Sex = Subject Sex **HC2_BBAVars:** data from
 observations of the subject animal in the holding cage during day 2 of the
 BBA events on year 1 or year 2. animid = unique identifier for each
 subject animal Y = year of BBA event sampling (1 or 2) HAP2 - VCR2 = rates
 (R suffix) or proportions (P suffix) for the relevant behaviors as
 detailed in the primary open access manuscript DAY2ACTIVITY = Infant BBA

 each subject animal Y = year of cumulative hospitalization data (0 [3-4

 Sharing/Access information These data are to supplement the associated
 publication from American Journal of Primatology (Article DOI:

 relevant *.csv files to replicate the exact values used in the
 manuscript's tables. Use setwd() to direct R to the file folder where
 you have placed the datafiles. Code relies on the plyr package for the
 ldply() function.
