Question

read the scenario below and answer the question that follows.

a vervent monkey is in a tree eating bugs that are crawling along the branches. the vervent monkey sees a hawk circling overhead. the hawk is a predator of the monkeys. the vervent monkey cries out, warning the other monkeys to descend to the ground below the trees.

in this scenario, what is the unconditioned stimulus for the vervent monkeys behavior?

a. the vervent monkey eating bugs
b. the vervent monkey crying out
c. the group of monkeys descending
d. the sight of the hawk circling

Explanation:

Identify the unconditioned stimulus

The unconditioned stimulus (US) is a stimulus that naturally, automatically, and unconditionally triggers a specific, unlearned response. In this scenario, the sight of a natural predator (the circling hawk) is an innate threat that naturally triggers fear and defensive behaviors (such as crying out or fleeing) without prior training or conditioning.

Analyze the options

• (A) The vervet monkey eating bugs is an ongoing baseline behavior, not the stimulus triggering the alarm.
• (B) The vervet monkey crying out is the behavioral response (unconditioned response) triggered by the threat.
• (C) The group of monkeys descending is a behavioral response to the alarm call.
• (D) The sight of the hawk circling is the environmental trigger (stimulus) that naturally produces the alarm response.

Answer:

• (A) the vervet monkey eating bugs
• (B) the vervet monkey crying out
• (C) the group of monkeys descending
• (D) the sight of the hawk circling (Correct answer)
