Question

12) In the three-phase experiment that examined habituation and spontaneous recovery of the startle response in the rat, stimuli presented in widely spaced time intervals produced whereas stimuli presented in shortly spaced time intervals producedand after a 24 hour break, presentation of stimuli in widely spaced time intervals produced a. Sensitization, habituation, spontaneous recovery b. Short-Term Habituation, Spontaneous Recovery, Long-Term Habituation c. Short-term Habituation, Long-Term, Habituation, Dishabituation d. Long.term Habituation, Short-Term, Habituation, Spontaneous Recovery 13) In the experiment above, evidence of spontaneous recovery of the startle response was seen in: Phase three, after short-term habituation was induced, the rat recovered the somewhat habituated startle response observed in the last few days of phase one Phase one, after the rats habituated to the loud sound and were given 24 hours off, they were startled once again in response to the loud sound Phase two, after long-term habituation was induced, the rat fully recovered the startle response in presentation to a novel loud sound Oh heck, I give up! None of these answers sound right to me. a. b. c. d. 14) When studying the rat startle response, if I wanted to induce habituation in one group and sensitization in the other, my independent variable would be: a. b. c. d. Foot shock A loud startling stimulus Puff of air to cornea Background noise

Answer 1

12)

In the three phase experiment, a long term habituation occured when the stimulus was presented in a widely spaced time duration. A short term habituation occured when stimulus was presented at a shorter duration, but a rest period produced the startled response in rats indicating a spontaneous recovery.

Answer. d. Long-term Habituation, Short-term Habituation Spontaneous Recovery.

13)

Answer. a. Phase three, after short-term habituation was induced, the rat recovered the somewhat habituated startle response observed in the last few days of phase one.

14)

Answer. b. A loud starting stimulus.
