In an experiment on conditioned taste aversions using rat subjects, one would expect taste to overshadow a food’s appearance.

Suppose a rat was exposed to a flashing light followed by electric shock for 3 days. On the fourth day, the rat is placed in an operant chamber where it can press a lever for food pellets. If the rat makes 40 responses per minute when no flashing light is present but only 20 responses per minute in the presence of a flashing light, the suppression ratio would be

What do we observe if a CS passes the summation test?

A rat is given 20 exposures to a flashing light stimulus. Then, the flashing light is presented paired with food delivery. Compared to a rat that did not receive the initial 20 exposures, this rat took a long time to develop a CR to the light. The slower learning is due to the

The independent variables are the procedures of an experiment.

The relative validity of a stimulus is determined by its

Blocking occurs when an added stimulus is redundant in terms of predicting the US.

What causal inference do subjects make after experience with a zero contingency?

Howard Liddell (who worked in Pavlov’s laboratory) once presented a metronome CS for food to an unrestrained dog. Which best describes what happened?
