Please address each of these items after reading the papers for this session. We will plan to discuss these issues and ideas more fully during class.
1. How can arousal modulation problems impact children's development? What role might such problems play in autism spectrum disorders (ASD)?
2. What are the characteristics of ASD related to stress?
3. What factors need to be considered when assessing physiological reactivity in individuals with ASD? Consider this question in terms of: (1) characteristics of ASD; (2) characteristics of assessment devices; and (3) characteristics of assessment setting and observation protocol.
4. If you could reliably identify that an individual with ASD had problems with arousal modulation, how might you help him/her to cope?
5. Try two of these (or similar) classic stress experiments with the galvactivator on yourself or on a good friend who is willing. These include physical, cognitive, and social stress elicitors, all of which have been shown to produce sympathetic arousal. Report to us what you tried and what happened.
a) Physical (Cold pressor test): Immerse non-glove hand in a bowl of ice water for 3 minutes.
b) Cognitive (Mental arithmetic): Without a calculator or pen and paper, multiple two numbers beginning at 1, then multiply the product by the next number, i.e., 1 x 2 = 2, 2 x 3 = 6, 6 x 7 = 42, 42 x 43, etc.
c) Social (Public speaking): Make a video recording of yourself talking about something, e.g., what you are learning in this class. (Make sure the camera shows the galvactivator.)
Note that it is advised to do some kind of relaxation before and after each stressor, setting the light to be very dim (just visible) after the baseline relaxation period. For example, you can experiment with progressive relaxation (eyes closed, focus attention on relaxing the eyes, nose, mouth, neck, chest, arms, legs, feet, etc.) and see if this makes the light go dim. (Some readings might also possibly have this relaxing affect.)
