After reading Fox et al., (2001) assigned in the “Prepare” folder and the Baby Human Fox Lab videos assigned in “Learn” answer the following questions. While this is a completion grade your answer must demonstrate that you have read and watched the assignment materials to receive credit for that questions.

1) Write a brief (~500 words) summary of Fox et al., (2001)

2) How does the Fox et. al (2001) study line up with the Thomas and Chess or Rohbart models of temperament? List 2 similarities. List 2 differences.

3) If you were accessing “Jack” in the video “Nathan Fox – The prohibitive plant” based on Thomas and Chess’s model of temperament, how would you classify him, and why?

4) If you were accessing “Emily” in the video “Nathan Fox – The prohibitive plant” based on Thomas and Chess’s model of temperament, how would you classify him, and why?

5) Define “Goodness of fit” using the examples provided in the video the “Prohibitive Plant”

Continuity and discontinuity of behavioral inhibition and exuberance: psychophysiological and behavioral influences across the first four years of life.

Four-month-old infants were screened (N = 433) for temperamental patterns thought to predict behavioral inhibition, including motor reactivity and the expression of negative affect. Those selected (N = 153) were assessed at multiple age points across the first 4 years of life for behavioral signs of inhibition as well as psychophysiological markers of frontal electroencephalogram (EEG) asymmetry. Four-month temperament was modestly predictive of behavioral inhibition over the first 2 years of life and of behavioral reticence at age 4. Those infants who remained continuously inhibited displayed right frontal EEG asymmetry as early as 9 months of age while those who changed from inhibited to noninhibited did not. Change in behavioral inhibition was related to experience of nonparental care. A second group of infants, selected at 4 months of age for patterns of behavior thought to predict temperamental exuberance, displayed a high degree of continuity over time in these behaviors.
