“…Both FXS and control groups displayed escape behaviors most frequently, with similar levels of intensity across groups and ages. The prominence of escape behaviors in our sample is consistent with previous studies using a stranger episode with 9-month-old infants (Diaz & Bell, 2011). Despite the similar behavioral profiles of escape across FXS and TD groups, only the typical controls displayed an association of increased arousal with escape behavior.…”

Anxiety is among the most impairing conditions associated with Fragile X syndrome (FXS) and is putatively linked to atypical physiological arousal. However, few studies have examined this association in young children with FXS. The authors examined whether patterns of arousal and behavior during an experimental stranger approach paradigm differ between a cross-sectional sample of 21 young children with FXS and 19 controls (12–58 months old). Groups did not differ in mean levels of behavioral fear. Unlike the control group, however, the FXS group demonstrated increased facial fear at older ages, as well as age-dependent changes in associations between heart activity and distress vocalizations. These findings may inform theoretical models of anxiety etiology in FXS and early detection efforts.

“…The stranger approach episode has been previously used with similar age groups to elicit behavioral variables (e.g., Aktar, Majdanzic, de Vente, & Bogels, 2012; Diaz & Bell, 2011; Kochanska, 1998). The stranger approach episode occurred at the same point in each child's assessment, directly following a nonstressful, engaging task.…”

“…Studies of asymmetry at rest indicate that left (relative to right) frontal asymmetry is indicative of approach behaviors and expression of positive emotions, and right (relative to left) asymmetry is associated with avoidance behaviors and expression of negative emotions (e.g., Calkins, Fox, & Marshall, 1996; Fox & Davidson, 1984; Fox, Henderson, Rubin, Calkins, & Schmidt, 2001; Smith & Bell, 2010). Studies of asymmetry in response to stimuli have shown similar results, whereby individuals who are exposed to negative avoidance or withdrawal related emotional stimuli – such as those that induce feelings of sadness – respond with greater right (relative to left) asymmetry, but those exposed to approach and positive emotion stimuli show greater left (relative to right) asymmetry (e.g., Coan & Allen, 2003, 2004; Diaz & Bell, 2012; Killeen & Teti, 2012). …”

It is well accepted that parent-child interactions are bidirectional by nature, yet not much is known about the psychophysiological activity underlying these interactions. We examined, during a parent-child interaction, how a child’s negativity statistically predicted maternal frontal EEG asymmetry and how a mother’s negativity statistically predicted child frontal EEG asymmetry. Thirty-four mother-child dyads participated in the study. Maternal and child behavior and physiology were measured during a puzzle task. Results indicated that mothers whose children exhibited more challenging behaviors during the dyadic interaction displayed more right (relative to left) asymmetry, as did children whose mothers were high in negativity during the interaction. These findings suggest that mothers and children react to each other’s signals, not only behaviorally but also physiologically.

“…Power was computed for the 6 to 9 Hz frequency band, as infants at this age have a dominant frequency between 6 and 9 Hz (Bell & Fox, 1994; Marshall, Bar-Haim, & Fox, 2002). This particular frequency band is thought to approximate the alpha band in adults and has been used in previous studies of infant frontal asymmetry (e.g., Bell & Fox, 1994; Buss et al, 2003; Diaz & Bell, 2012; Fox et al, 1992; Fox et al, 2001; Smith & Bell, 2010). For the current study, EEG power was expressed as mean square microvolts and the data transformed using the natural log (ln) to normalize the distribution.…”

Given the importance of children's self-regulation, relations were examined between two fundamental components of self-regulation, specifically temperamentally-based reactivity and regulation. Infant negative emotional reactivity and regulation, measured via frontal EEG asymmetry, were examined as potential precursors to understanding toddlerhood regulation, conceptualized as effortful control. Our longitudinal design allowed for examination of two perspectives on the interplay of reactivity and regulation: 1) early negative affectivity interferes with the development of later regulation or 2) regulation is necessary to modulate negative affectivity and thus buffer the effects of negative affectivity on later regulation. Mother-child dyads participated in a 3-wave longitudinal study. Baseline frontal EEG asymmetry was assessed at 10 months (T1). Mothers rated children's negative reactivity at both 10 and 24 months (T2). Children's effortful control, measured at 30-36 months (T3), was a composite score of maternal ratings and observed behavior during a snack delay. Negative affectivity was related to effortful control; however, significant interactions between negative affect and frontal EEG asymmetry were found. Higher levels of negative affectivity, at both T1 and T2, were associated with lower levels of effortful control at T3 but only for toddlers who also had right frontal EEG asymmetry. Negative affectivity was not associated with effortful control for the left frontal EEG asymmetry group. Our moderation findings highlight the complex relations of negative affect and frontal EEG asymmetry in understanding children's development of self-regulation, specifically effortful control. The interaction between early reactivity and physiological regulation indicate that both may be important precursors of effortful control.
