Question 1

Explain what ethologists mean by a "sensitive period," and provide one example of a characteristic that has a sensitive period.

Accepted Answer

Ethologists use the term "sensitive period" to describe a specific window of time during an organism's development when it is particularly responsive to certain stimuli. This period is crucial for the development of specific behaviors, skills, or characteristics, and if the organism does not receive the necessary stimuli during this time, it may have long-lasting or permanent effects on their development.

One example of a characteristic that has a sensitive period is language acquisition in humans. Research has shown that there is a critical period during early childhood when children are most receptive to learning language. If a child does not have exposure to language during this sensitive period, they may struggle with language acquisition later in life. This highlights the importance of early language exposure and the impact it can have on a child's development.
