Abstract(s)
Three infant regulatory behavior patterns have been identified during the Face-to-Face Still-
Face paradigm (FFSF) in prior research samples: a Social-Positive Oriented pattern (i.e.,
infants exhibit predominantly positive social engagement), a Distressed-Inconsolable pattern
(i.e., infants display conspicuous negative affect that persists or increases across FFSF episodes),
and a Self-Comfort Oriented pattern (e.g., infants primarily engage in self-comforting
behaviors such as thumb-sucking). However, few studies have examined these patterns outside
US and European countries or evaluated potential cross-country differences in these
patterns. In this study, we compared the regulatory behavior patterns of 74 Brazilian and 124
Portuguese infants in the FFSF at 3 months of age, and evaluated their links to demographic
and birth variables. The prevalence of the three regulatory patterns varied by country. The
most frequent pattern in the Portuguese sample was the Social-Positive Oriented, followed
by the Distressed-Inconsolable and the Self-Comfort Oriented. However, in the Brazilian
sample, the Distressed-Inconsolable pattern was the most prevalent, followed by the Social-
Positive Oriented and the Self-Comfort Oriented. Moreover, in the Brazilian sample, familial
SES was higher among infants with a Social-Positive pattern whereas 1st-minute Apgar
scores were lower among Portuguese infants with a Distressed-Inconsolable Oriented pattern
of regulatory behavior. In each sample, Social Positive pattern of regulatory behavior
was associated with maternal sensitivity, Self-Comfort Oriented pattern of regulatory behavior
with maternal control, and Distressed-Inconsolable pattern with maternal unresponsivity.
