Final answer:
Based on the "Early Development" lecture in Psychology, the person with the weakest fear response to being on the edge of a cliff would be someone who has experienced learned helplessness.
Step-by-step explanation:
Based on the Psychology in the News from the "Early Development" lecture, the person who would have the weakest fear response to being on the edge of a cliff would be someone who has experienced learned helplessness.
Learned helplessness refers to a psychological phenomenon where individuals feel helpless and powerless in situations where they lack control. This feeling of helplessness can lead to a reduced fear response because the person believes they have no control over the situation and cannot escape the danger. An example of learned helplessness is when dogs in an experiment were exposed to electric shocks they could not escape, causing them to give up trying to escape when given the opportunity later.
Therefore, someone who has experienced learned helplessness is more likely to have a weaker fear response to being on the edge of a cliff because they may believe they have no control over the situation and cannot escape.
