Which of the following are the two most important emotional expressions that infants display when interacting with their parents?

Smiles

Cries

Frowns

Expressions of disgust

Answers

Answer 1

The two most significant emotional expressions that newborns use while engaging with their parents are smiles and crying.

An emotional expression is a behavior that expresses an emotional state or attitude. It might be verbal or nonverbal, self-aware or not.

Paul Ekman's widely recognized theory of fundamental emotions and how they manifest argues that there are six basic emotions. Sadness, joy, anxiety, rage, surprise, and disgust are among them.

The fight-or-flight response is frequently triggered in our brains when we are unable to communicate our feelings. This is a physiologic response to stress that starts a series of processes happening all over our bodies. Our hearts beat faster, our digestion moves more slowly, and we experience anxiety or depression as a result.

Which type of feedback would not be recommended for someone low in confidence, when trying to determine exercise self-efficacy?

A. Encourage your client to be a mentor to someone else.
B. Work on increasing confidence by developing realistic strategies.
C. Let your client know you believe in their ability to increase their physical activity.
D. Discuss what went wrong during previous attempts at behavior change.

Answers

Self-efficacy refers to confidence in one's own ability to perform a specific mode of effective behavior.

In the event that you accept that you can play a way to behave effectively, you will be required to participate in that way of behavior. Assuming, for example, that you are confident that you can ski down a mountain without falling, you are more likely to be forced to ski downhill than someone who admits that such activities will bring considerable mischief.

Research has shown that beliefs about one's own viability influence the adoption of new well-being behaviors, their adaptation to changing conditions, and their maintenance over time.
