Question 5

An infant's emotional reactivity and intensity is referred to as its temperament.

Temperament describes the inherent characteristics of an infant that influence their emotional responses and intensity. It captures the enduring patterns of emotional reactivity and self-regulation observable from a very young age.

A) Attitude

Attitude refers to an individual's settled way of thinking or feeling about something, typically shaped by experiences and beliefs. While attitudes may develop in early childhood, they are not the same as temperament, which is more about innate emotional responses.

B) Emotionality

Emotionality pertains to the intensity and type of emotions an individual experiences. While it plays a role in the broader concept of temperament, emotionality alone does not encompass the entirety of the emotional reactivity and intensity that temperament describes.

C) Heritability

Heritability is a genetic concept that refers to the proportion of variation in a trait attributable to genetic factors. It does not describe the emotional reactivity and intensity of an infant, making it unrelated to the definition of temperament.

D) Personality

Personality is a broader construct that develops over time and encompasses a range of attributes, including temperament. However, personality is not specifically about the immediate emotional reactivity and intensity observed in infants, which is more accurately described by temperament.

E) Temperament

Temperament is the correct term for an infant's emotional reactivity and intensity. It refers to the biologically based individual differences in emotional functioning that are observable from early in life, making it the most precise choice in this context.

Conclusion

Temperament is definitively the correct answer as it directly addresses the emotional reactivity and intensity of an infant, distinguishing it from concepts like attitude, emotionality, heritability, and personality, which do not fully capture this specific aspect of early emotional development. All other options fail to accurately define the innate emotional characteristics present in infants.
