  • Trier Social Stress Test- Cortisol

    Participants will be met by two research assistants (one male, one female), whom they have not met previously. The research assistants will tell the participants that they will have 5 minutes to prepare a speech which they will give to the researchers who will rate the speech. Participants will then give their speeches for 5 minutes; the research assistants will maintain neutral expressions and provide no feedback. Afterwards, participants will be asked to do (age-adjusted) mental arithmetic aloud (Buske-Kirschbaum et al.,1997). For the purpose of assessing cortisol, investigators will collect saliva samples before and after the speech/math.

    Age 13 years

  • Trier Social Stress Test-ANS

    Participants will be met by two research assistants (one male, one female), whom they have not met previously. The research assistants will tell the participants that they will have 5 minutes to prepare a speech which they will give to the researchers who will rate the speech. Participants will then give their speeches for 5 minutes; the research assistants will maintain neutral expressions and provide no feedback. Afterwards, participants will be asked to do (age-adjusted) mental arithmetic aloud (Buske-Kirschbaum et al.,1997).Assess child autonomic nervous system regulation, examine reactivity from baseline in RSA.

    Age 13 years

  • Revealed differences task - parent sensitivity.

    Parents and children engage in conflict discussion. Assess parental sensitivity using Sensitivity scale. Parental behavior is scored on a 1-7 scale, with higher scores reflecting greater sensitivity.

    Age 13 years

  • Support task- parent sensitivity

    Parents and children engage in support discussion (discussing Trier task from previous year). Assess parental sensitivity using Sensitivity scale. Parental behavior is scored on a 1-7 scale, with higher scores reflecting greater sensitivity.

    Parents and children engage in conflict discussion. Assess child competence in discussion on Competence scale. Competence is scored on a 1-7 scale, with higher scores reflecting greater competence.

    Age 13 years

  • Support task-adolescent competence

    Parents and children engage in conflict discussion. Assess child competence in discussion on Competence scale. Competence is scored on a 1-7 scale, with higher scores reflecting greater competence.

  • Revealed differences task-adolescent ANS

    The control of cardiac functions via the vagal nerve, or vagal tone, is an index of parasympathetic activity. It can be measured by heart rate variability associated with respiration or high frequency respiratory sinus arrhythmia (RSA). RSA data will be collected continuously throughout the parent-child interaction using a MindWare Portable Lab system. Greater changes in RSA from baseline to discussion considered preferable. Parents and children engage in conflict discussion. Assess child autonomic nervous system regulation. Respiratory sinus arrhythmia (RSA) will be measured as a rise from baseline.

  • Balloon Analogue Risk Task (BART)

    This task assesses risk-taking through a computer game in which participants see a balloon on the computer screen and have the option of pumping up the balloon more, and therefore increasing its monetary value, or stopping and collecting the value of the balloon. If the balloon pops on a pump, then all of the value of the balloon is lost and the next trial begins. There is a randomly, pre-determined probability of the balloon popping on any given pump of each trial. A brief version of the task with 15 balloons will be used. A running tally of participants' total monetary gain is kept (and can range from $0 up to a cap of $5). The amount of money earned is the score, with more money reflecting higher risk taking.

  • Delay Discounting

    Delay Discounting Task is a brief, five-item task on a computer that asks participants their preference between $5 now and $10 at some later time point (Koffarnus, Warren, \& Bickel, 2014). No money is actually earned on this task. A score from 0 to 5 is received with lower score indicating better delay (preferred).
