“…Infants who erred on the reversal trials demonstrated less developed WMIC skills and showed no change in EEG power values from baseline to task (Bell, 2001). Infants show a similar pattern of increase in EEG power values from baseline to task during sustained attention Stroganova, Orekhova, & Posikera, 1998 and cortical inhibition tasks (Orekhova, Stroganova, & Posikera, 2001) as well.…”

“…Infant EEG recorded during working memory and sustained attention tasks exhibits task-related EEG changes at both anterior and posterior scalp locations (Bell, 2001(Bell, , 2002Orekhova et al, 2001). The unique contribution of left frontal EEG in this study may be indicative of brain reorganization towards increasing specialization from infancy to early childhood.…”

This study examined the cognitive skills of working memory and inhibitory control (WMIC) in relation to physiological functioning, temperament, and language in early childhood. WMIC skills were assessed in twenty-five 4 1 2 -yearold children using the day-night Stroop-like task and the yes-no task; each task required the child to remember two rules and to inhibit a dominant response. Electroencephalogram (EEG) and heart period (HP) were recorded during baseline and WMIC tasks. An increase in 6-to 9-Hz EEG power from baseline to task was found for the medial frontal region. In addition, a decrease in HP (i.e., an increase in heart rate) was found from baseline to task. Associations were found between performance on the WMIC tasks and scales of the Children's Behavioral Questionnaire (CBQ) related to the effortful control of behavior. The Peabody Picture Vocabulary Test-III (PPVT-III) distinguished between high and low WMIC performance. Results of a discriminant function analysis indicated that physiology, temperament, and language were able to correctly predict 90% of WMIC performance. Keywords: working memory; inhibitory control; prefrontal cortex; temperament; language; EEG; heart period Executive function skills, such as working memory, inhibitory control, planning, and attentional flexibility, are typically associated with the prefrontal cortex. Two of these skills, working memory and inhibitory control (WMIC), have been the focus of much behavioral

“…Specifically, this work has shown a relation between scalp-recorded EEG measures of power and coherence in the 6-9 Hz frequency band and performance on WM and IC tasks in both infancy and early childhood. At infancy, WM performance is associated with widespread brain electrical activity in multiple anterior and posterior scalp locations (Bell, 2002;Orekhova, Stroganova, & Posikera, 2001). However, by early childhood, WM performance was particularly associated with changes in EEG power and coherence from baseline-to-task in medial frontal scalp locations, areas that arguably represent prefrontal cortex activation.…”

EEG power and coherence during preschoolers' performance of an executive function battery

The current study investigated a set of abilities collectively referred to as executive function (EF). Substantial improvement in EF ability occurs between 3 and 6 years of age (e.g., Carlson [2005] Developmental Neuropsychology, 28(2):595-616). This improvement is thought to reflect changes in brain development, especially in areas of prefrontal cortex and frontal cortex, which occur during this time period (e.g., Luu & Posner [2003] Brain 126:2119-2120). Little work has examined preschoolers' cortical activity during EF tasks, despite the frequent use of performance on such tasks as indirect measures of (pre)frontal functioning. The current study measured continuous EEG activity in 104 preschool aged children as they completed a battery of EF tasks. Changes from baseline to task performance in EEG activity (power, coherence) were used as predictors of EF ability. Results indicated that changes from baseline to task engagement in EEG coherence, but not EEG power, were significantly related to performance on the EF battery in our sample.

“…However, during sustained visual attention alpha from 6.0 to 8.8 Hz increases at precentral recording sites [24], similar to the so-called mu rhythm observed in adults (∼10 Hz), which increases in association with a top-down inhibition of the activity involved in task-irrelevant cortical areas [27]. Similarly, 8- to 11-month-old infants, who exhibit longer alertness in a peak-a-boo game, show a greater increase in alpha (6.8 Hz), even in posterior regions of the scalp [28], showing that infants' alpha is functionally similar to adults' mu rhythm. …”

Mother-Infant Face-to-Face Interaction: The Communicative Value of Infant-Directed Talking and Singing

Background: Across culture, healthy infants show a high interest in infant-directed (ID) talking and singing. Despite ID talking and ID singing being very similar in physical properties, infants differentially respond to each of them. The mechanisms underpinning these different responses are still under discussion. Methods: This study explored the behavioral (n = 26) and brain (n = 14) responses from 6- to 8-month-old infants to ID talking and ID singing during a face-to-face mother-infant interaction with their own mother. Behavioral response was analyzed from offline video coding, and brain response was estimated from the analysis of electrophysiological recordings. Results: We found that during ID talking, infants displayed a significantly higher number of visual contacts, vocalizations, and body movements than during ID singing. Moreover, only during ID talking were the number of visual contacts and vocalizations positively correlated with the number of questions and pauses in the mother's speech. Conclusions: Our results suggest that ID talking provides infants with specific cues that allow them not only to react to mother stimulation, but also to act toward them, displaying a rudimentary version of turn-taking behavior. Brain activity partially supported that interpretation. The relevance of our results for bonding is discussed.
