“…Furthermore, reliability analyses can also complement our examination of developmental change, because our interpretation of frontal alpha asymmetry is consistently reliable across assessments. For example, Hill et al (2020) recently compared frontal alpha asymmetry between mothers and infants and reported high heritability estimates, providing evidence for the theorized trait-like nature of this neural marker. Their findings were complemented by split-half reliability analyses of a 3-min task, showing that frontal alpha asymmetry had good psychometric properties (Reported αs = 0.74-0.90) across mothers and children.…”

“…Only participants who provided >60 s (>120 segments) of artifactfree EEG data during either the lights-on or lights-off condition were retained in these analyses. This decision was based on findings from Hill et al (2020), showing that adequate internal consistency in infant frontal alpha asymmetry can be achieved with this number of segments. Spectral power in the 6-9 Hz frequency range was natural log transformed for electrode channels Fp1, Fp2, F3, F4, F7, and F8.…”

“…Although there have been some landmark studies assessing the basic psychometric properties of EEG in young samples (Brooker et al, 2017;Hill et al, 2020;Howarth et al, 2016;Jones et al, 1997), our field would benefit from more detailed and nuanced examinations of the psychometrics of this method in infancy, both at any one time point and across time. For example, Marshall et al (2002) reported on EEG power at the level of single hertz bins from 5 to 51 months of age in order to capture the most appropriate window for measures of infant alpha power.…”

Resting‐state electroencephalography (EEG) provides developmental neuroscientists a noninvasive view into the neural underpinnings of cognition and emotion. Recently, the psychometric properties of two widely used neural measures in early childhood—frontal alpha asymmetry and delta–beta coupling—have come under scrutiny. Despite their growing use, additional work examining how the psychometric properties of these neural signatures may change across infancy is needed. The current study examined the developmental stability, split‐half reliability, and construct validity of infant frontal alpha asymmetry and delta–beta coupling. Infants provided resting‐state EEG data at 8, 12, and 18 months of age (N = 213). Frontal alpha asymmetry and delta–beta coupling showed significant developmental change from 8 to 18 months. Reliability for alpha asymmetry, and alpha, delta, and beta power, individually, was generally good. In contrast, the reliability of delta–beta coupling scores was poor. Associations between frontal alpha asymmetry and approach tendencies generally emerged, whereas stronger (over‐coupled) delta–beta coupling scores were associated with profiles of dysregulation and low inhibition. However, the individual associations varied across time and specific measures of interest. We discuss these findings with a developmental lens, highlighting the importance of repeated measures to better understand links between neural signatures and typical and atypical development.

Prior work has provided conceptual support for developmental changes in face and object processing, such that: face processing, as captured by the N290 event-related potential (ERP) component in infancy, may develop into the N170 in adulthood; and motivated attention, as captured by the negative central (Nc) in infancy, may develop into the late positive potential (LPP). The present study examined these neural correlates in 12-month-old infants and their mothers (N = 33 dyads). Dyads completed a viewing task consisting of familiar and novel face and toy stimuli while electroencephalography was recorded. Results suggest that for mothers, the N170 was larger for faces than toys, regardless of familiarity, and the LPP was largest for familiar faces.In infants, the N290 was somewhat larger for faces than toys (p < .10); the Nc did not vary by condition. Adult ERPs demonstrated fair to good reliability; reliability of infant ERPs was lower and was influenced by looking behaviors. Intergenerational associations were strongest between the LPP and Nc, particularly when electrode and time window were taken into account. Refinement of data handling and ERP scoring procedures for infant ERPs are crucial next steps for estimation of intergenerational associations and further examination of developmental changes in face and object processing.

“…frequency bands that reflect a genuine underlying neural oscillator. Research suggests that infant theta ranges from 2-6 Hz (Jones et al, 2015;Michel et al, 2015) whereas infant alpha ranges from 6-9 Hz (Hill et al, 2019). While a 6-9 Hz alpha band peak may emerge by the end of the first year, in one study (Xie et al, 2018) only 7% of infants at the age of 6 moths exhibited a distinct peak in this range, leading the authors to suggest that infant activity in the neighboring theta band "may be a more reliable neural index of infant cognitive processes in the first few months of life".…”

Affective Cortical Asymmetry at the Early Developmental Emergence of Emotional Expression

Emotions have an important survival function. Vast amounts of research have demonstrated how affect-related changes in physiology promote survival by effecting short and long-term changes in adaptive behavior. However, if emotions truly serve such an inherent function, they should be pervasive across species and be established early in life. Here, using electroencephalographic (EEG) brain activity we sought to characterize core neurophysiological features underlying affective function at the emergence of emotional expression, i.e., at the developmental age when human infants start to show reliable stimulus-elicited emotional states (4-6 months). Using an approach which eschews traditional EEG frequency band delineations (like theta, alpha), we demonstrate that negative emotional states induce a strong right hemispheric increase in the prominence of the resonant frequency (~5-6 Hz) in the infant frontal EEG. Increased rightward asymmetry was strongly correlated with increased heart rate responses to emotionally negative compared to neutral states. We conclude that functional frontal asymmetry is a key component of emotional processing and suggest that the rightward asymmetry in prominence of the resonant frequency during negative emotional states might reflect functional asymmetry in the central representation of anatomically-driven asymmetry in the autonomic nervous system. Our findings indicate that the specific mode hallmarking emotional processing in the frontal cortex is established in parallel with the emergence of stable emotional states very early during development, despite the well-known protracted maturation of frontal cortex. 3 Significance Statement Emotions provide an important survival function and are associated with unique brain states that should theoretically be present early in life. In this paper, we demonstrate in 4-6 month infants (i.e. when infants first reliably express emotions) that negative emotions are linked to increased prominence in the resonant EEG frequency of the right compared to left frontal cortex. The extent of this asymmetry was linked to heart rate reactivity. These results show that emotion induces asymmetric patterns in brain activity at the emergence of emotional expression, possibly laying the foundation for more complex functional asymmetries observed later in life.
