1.

Read the scenario below and answer the following question. A nursing mother responds to the crying of her infant by putting the infant to her breast, which stimulates the delivery of milk. After this has occurred several times the sound of the baby crying stimulates the milk letdown reflex. What is the conditioned stimulus (CS) in this situation?
- A.
  
  Infant to her breast
- B.
  
  Delivery of milk
- C.
  
  Crying infant
- D.
  
  Nursing mother
Correct Answer
C. Crying infant

Explanation
The conditioned stimulus (CS) in this situation is the crying infant. This is because after the nursing mother has repeatedly responded to the crying by putting the infant to her breast, the sound of the baby crying becomes associated with the delivery of milk. As a result, the crying infant becomes a conditioned stimulus that can stimulate the milk letdown reflex.

After this has occurred several times the sound of the baby crying stimulates the milk letdown reflex. What is the unconditioned stimulus (US) in this situation?
- A.
  
  Infant to her breast
- B.
  
  Delivery of milk
- C.
  
  Crying infant
- D.
  
  Nursing mother

- B.
  
  Delivery of milk
- C.
  
  Crying infant
- D.
  
  Nursing mother
Correct Answer
B. Delivery of milk

Explanation
The conditioned response (CR) in this situation is the delivery of milk. This is because the nursing mother has learned to associate the sound of the baby crying with the act of breastfeeding, which in turn stimulates the release of milk. Therefore, the delivery of milk is the response that is conditioned to occur in response to the crying infant.

Read the scenario below and answer the following question. A nursing mother responds to the crying of her infant by putting the infant to her breast, which stimulates the delivery of milk. After this has occurred several times the sound of the baby crying stimulates the milk letdown reflex. What is the unconditioned response (UR) in this situation?
- A.
  
  Infant to her breast
- B.
  
  Delivery of milk
- C.
  
  Crying infant
- D.
  
  Nursing mother

In a bidirectional response system, subjects move away from an excitatory CS. You expect the subjects to _____ an inhibitory CS.
- A.
  
  Move away from
- B.
  
  Approach
- C.
  
  Show inhibition of delay to
- D.
  
  It cannot be determined
Correct Answer
B. Approach

Explanation
In a bidirectional response system, subjects move away from an excitatory CS. Therefore, it can be inferred that the subjects would approach an inhibitory CS.

Taste aversion learning can occur under which of the following circumstances?
- A.
  
  After just one CS-US pairing
- B.
  
  Only if the subject is hungry
- C.
  
  Only with very long delays between the CS and US
- D.
  
  Only with tastes the subject knows well
Correct Answer
A. After just one CS-US pairing

Explanation
Taste aversion learning can occur after just one CS-US pairing. This means that an individual can develop an aversion to a certain taste or food after experiencing it in association with an unpleasant or negative stimulus (US) just once. Unlike other forms of classical conditioning, taste aversion learning does not require multiple pairings or reinforcement. This type of learning is unique because it can happen quickly and can have long-lasting effects on an individual's preferences and behavior towards certain tastes or foods.

The interstimulus interval refers to which of the following time periods?
- A.
  
  Between the start of the CS and the end of the US
- B.
  
  Between the start of the CS and the start of the US
- C.
  
  Between the end of the CS and the start of the US
- D.
  
  Between the end of the US and the start of the next CS
Correct Answer
B. Between the start of the CS and the start of the US

Explanation
The interstimulus interval refers to the time period between the start of the conditioned stimulus (CS) and the start of the unconditioned stimulus (US). This interval represents the time delay between the presentation of the CS and the occurrence of the US, which is important in classical conditioning as it affects the strength and effectiveness of the learned association between the two stimuli.

Therefore, the teddy bear has become a conditioned stimulus that elicits a positive response from the child.
