After Researchers Conditioned a Dog to Salivate to the Sight

question 59

Multiple Choice

After researchers conditioned a dog to salivate to the sight of a triangle, they presented the triangle alone to the dog every three minutes. Over the course of several trials, the amount of saliva the dog secreted in response to the triangle decreased to zero. At that point, the researchers put the dog back in his cage for the night. What happened the next morning when the researchers presented the triangle to the dog again?

• A) Because of latent learning, the dog did not salivate.
• B) Spontaneous recovery likely occurred, and the dog salivated in response to the triangle.
• C) Learned helplessness developed, and the dog did not respond in any way.
• D) Because the triangle was no longer a discriminative stimulus, the dog did not salivate.
