简要总结
The purpose of this experiment is to determine whether social buffering by friends of stress physiology remains effective later in puberty when friends share the load versus when they provide support but are not undergoing the stressor with the target child. There are four conditions: (1) Friend and Target both undergo the stressor, (2) Friend provides support but does not undergo the stressor, (3) Unfamiliar Peer and Target undergo the stressor, and (4) Alone (no partner).
详细描述
Adolescents experience social evaluation stress frequently. However, it is likely that often they are not alone, but with friends who are also going through the same experience. Thus, it is possible that under these conditions, social buffering by friends does not wane over the peripubertal period. Participants will be assigned to social conditions while engaging in an evaluative stressor task.

结局指标
主要结局
Cortisol AUCi
时间窗: 2 hours
Cortisol response to the TSST, measured as Area Under the Curve, increase from baseline. 7 Samples were taken during the course of the assessment, at (1) arrival for training purposes; (2) after the calming video, 30 minutes after arrival; (3) after 5 minutes of speech preparation; (4) after 10+minutes of speech and math performance; (5) 15 minutes after sample 4; (6) 10 minutes after sample 5; (7) 10 minutes after sample 6. Area under the curve at intercept (AUCi) is calculated using samples 2-7 with sample 2 as the intercept.
sAA AUCi
时间窗: 2 hours
Salivary Alpha Amylase response to the TSST, measured as Area Under the Curve, increase from baseline. 7 Samples were taken during the course of the assessment, at (1) arrival for training purposes; (2) after the calming video, 30 minutes after arrival; (3) after 5 minutes of speech preparation; (4) after 10+minutes of speech and math performance; (5) 15 minutes after sample 4; (6) 10 minutes after sample 5; (7) 10 minutes after sample 6. Of those, samples (2, 4, 5) are assayed for salivary alpha amylase (sAA) in micrograms per milliliter. Area under the curve at intercept (AUCi) is calculated using samples 2, 4, 5 with sample 2 as the intercept.
