Answer:
Darren is using C. shaping to get his son to eat his peas.
Explanation:
Shaping is a tactic used within Operant Conditioning, which is understood as the process for a subject to <em>acquire a certain behavior</em> through reinforcements.
Shaping occurs when the reinforcements occur during a successive pattern of the behavior, not only whenever a behavior is present.
We can see it clearly in this example; Darren <em>slowly starts to praise </em>(reinforce) his son's behaviors, <em>gradually moving</em> from moving his fork towards the peas until he moves the fork with the pea to its mouth.
In my view, the answer is: Compared with boys, girls are more likely to play in a. small groups. Because boys are less likely to demonstrate social modesty than girls. Girls like to spend their time with their friends, while boys don't about it and spend their time in larger groups.
This situation illustrates emotional contagion.
This means that among infants, emotions are contagious - so if one child starts crying, it will 'contaminate' other infants with its feelings, and then all of them will start crying in chorus, sharing the same feelings even though they might not feel sad or the need to cry at all.
