Neurophysiology of predictable unpleasant event processing in pre-adolescents and early adolescents, part II: Reflex and event-related potential markers of defensive reactivity and peripheral attention modulation.

The ability to anticipate and process predictable unpleasant events, while also regulating emotional reactivity, is an adaptive skill. The current article and a companion in this issue test for potential changes in predictable event processing across the childhood-to-adolescence transition, a key developmental period for biological systems that support cognitive/ emotional abilities. While the companion article focuses on neurophysiology of predictable event processing itself, the present article examines peripheral emotional response regulation and attention modulation that coincides with event processing. A total of 315 third-, sixth-, or ninth-grade individuals saw 5-s cues predicting "scary," "every day," or uncertain pictures, and here, blink reflexes and brain event-related potentials (ERPs) elicited by peripheral noise probes are analyzed. During the cue, blink reflexes and probe ERP (P200) amplitudes were increased when the cue predicted scary, compared to everyday, content. After picture onset, reflex enhancement by scary content then disappeared for predictable images, whereas ERP modulation was similar regardless of predictability. Patterns are similar to those in adults and suggest (1) sustained defensive response priming and enhancement of peripheral attention during aversive anticipation, and (2) an ability, even in pre-adolescents, to downregulate defensive priming while maintaining attentional modulation once an awaited predictable aversive event occurs.

Neurophysiology of predictable unpleasant event processing in preadolescents and early adolescents, part I: Event-related potential markers of unpleasant image anticipation and processing.

The ability to anticipate and process predictable unpleasant events, while also regulating emotional reactivity, is an adaptive skill. The current article and a companion in this issue test for potential changes in predictable event processing across the childhood-to-adolescence transition, a key developmental period for biological systems that support cognitive/emotional abilities. While the companion article focuses on emotion regulation and peripheral attention modulation in predictable unpleasant contexts, the current paper presents neurophysiological markers of predictable event processing itself. 315 third-, sixth-, or ninth-grade individuals saw 5-s cues predicting "scary," "every day," or uncertain image content; in this paper, cue- and picture-locked event-related potentials (ERPs) are analyzed. During the cue, early ERP positivities were increased and later slow-wave negativities were reduced when predicted content was scary as compared with mundane. After picture onset, a picture processing-related positivity was then increased for scary compared with everyday images regardless of predictability. Cue-interval data suggest enhanced processing of scary cues and reduced anticipatory processing of scary images-opposite to adults. After event onset, meanwhile, emotional ERP enhancement regardless of predictability is similar to adults and suggests that even preadolescent individuals maintain preferential engagement with unpleasant events when they are predictable.

A qualitative analysis of black mother preparation for bias messages following incidents of racism-related violence.

Preparation for bias messages (PFB), represent a specific form of racial socialization, used to inform youth about racism and how to cope with racism-related adversity. Although research commonly examines how frequently PFB are delivered to children, few studies have qualitatively explored the heterogeneity in the content of such messages, making it difficult to ascertain how caregivers prepare and coach their children to negotiate incidents of racism-related violence. To address this gap in the literature, the present study qualitatively examined the content of PFB given to Black children from their mothers following high-profile incidents of anti-Black violence. Semistructured interviews were conducted with 12 mothers (Mage = 41.91) of Black children to explore how parental concerns regarding their children's safety inform the content of their PFB. Using thematic analysis, two primary themes emerged. The first theme related to psychosocial factors among caregivers that precipitated PFB (i.e., awareness of anti-Black violence, worry about the child being a victim). The second theme pertained to the different types of PFB that caregivers provided to their children (i.e., awareness of racial biases, strategies to navigate discriminatory encounters). Overall findings support and extend extant racial socialization research and have important implications for how Black youth come to understand the significance of race and racism in the aftermath of racism-related violence.

The role of child maltreatment and adolescent victimization in predicting adolescent psychopathology and problematic substance use.

BACKGROUND: Maltreated children are more likely to experience adolescent victimization, which may underlie the association between maltreatment and adolescent psychopathology and substance use. OBJECTIVE: To determine whether number of adolescent victimization types predicts adolescent psychopathology and problematic substance use over and above number of child maltreatment subtypes; whether adolescent victimization mediates the relations between maltreatment and change in adolescent psychopathology and problematic substance use; and whether maltreatment moderates the relation between adolescent victimization and changes in these outcomes. PARTICIPANTS AND SETTING: Participants were 545 (295 maltreated, 250 non-maltreated; 328 males, 217 females) racially and ethnically diverse (52.8 % Black, 27.5 % White, 12.8 % Bi-racial; 13.4 % Latino/a) children and families from the Rochester, New York, USA area assessed across three waves of data (Wave 1, Mage = 7.6 years; Wave 2, Mage = 13.8 years; Wave 3, Mage = 16.2 years). METHODS: Maltreatment was coded at Wave 1 using Department of Human Services records. Adolescents self-reported psychopathology, problematic substance use, and victimization at Waves 2 and 3. RESULTS: Structural equation modeling revealed that adolescent victimization predicted adolescent psychopathology (ß = 0.24, p < .001) and problematic substance use (ß = 0.27, p < .001) over and above child maltreatment. Adolescent victimization did not mediate the association between child maltreatment change in psychopathology and problematic substance use and child maltreatment did not moderate the association between adolescent victimization and these outcomes. CONCLUSIONS: We discuss the importance of future research utilizing multi-wave designs to examine relations between these constructs and of assessing for more proximal victimization.
