Question

because maddy always picked up her newborn daughter when she cried, her daughter is now a real crybaby. in this case, picking up the infant served as a(n)______ for crying
a) negative reinforcer
b) positive reinforcer
c) negative punishment
d) positive punishment

Explanation:

Reinforcement increases behavior frequency. Positive reinforcement adds a desirable stimulus after the behavior to strengthen it. Here, picking up the infant (a desirable stimulus) follows crying, making crying more frequent (the daughter is a "crybaby"). Negative reinforcement removes an aversive stimulus; punishment decreases behavior, which does not apply here.

Answer:

B) positive reinforcer
