Step 1: Understanding the Concept:
This matching task focuses on the developmental timeline of emotional expression in infancy, based on studies by Izard and colleagues.
Step 2: Detailed Explanation:
Let us look at when each of these basic infant emotions typically emerges:
(A) Distress:
Distress is a basic, physiological survival response to discomfort, pain, or hunger.
It is present at birth, typically expressed through crying.
Hence, (A) matches with (III) Present at birth.
(B) Fear:
Fear, including stranger anxiety or wariness of novel stimuli, develops later in infancy as cognitive and memory capacities mature.
It typically begins to emerge around 5--7 months of age.
Hence, (B) matches with (IV) 5-7 Months.
(C) Anger:
Anger begins to emerge around 3--4 months of age as infants develop a clearer sense of goal-directed actions.
They express anger when their goals are blocked or when they experience frustration.
Hence, (C) matches with (I) 3-4 Months.
(D) Social smile:
A true social smile, which occurs in response to human faces and social interaction rather than physiological states, typically emerges between 4 to 6 weeks of age.
Hence, (D) matches with (II) 4-6 Weeks.
Step 3: Final Answer:
Matching the emotions with their developmental stages gives:
(A) - (III), (B) - (IV), (C) - (I), (D) - (II).
This corresponds to Option (A).
