central question (topic of interest)
do infants show a developing fear of heights as they gain locomotive experience?
argument
evidence
-Researchers often discuss heart rate as an indicator of fear (infants placed on the cliff show increased heart rate), but those infants with racing hearts still cross the cliff
analysis
If increased heart rate was an indicator of fear, the infants with racing hearts would not have crossed the cliff (they would have been afraid and avoided crossing)
evaluation
Perhaps racing heart is an indicator of “interest” not fear per se
