Hi To answer my own question ... "yes." That is, people have studied immediate vs delayed extinction and at least some findings support the idea that delayed extinction is more effective (i.e., less spontaneous recovery). See, for example:

Also mentions initial representation of stimulus (blue square) without shock before the extinction proper. Has anyone studied effect of immediate vs delayed extinction? Might the phenomenon of spontaneous recovery suggest benefits of delayed extinction? Take care Jim James M.

Oversimplified, but interesting. http://news.yahoo.com/s/nm/20091209/sc_nm/us_fear_memory Carol DeVolder, Ph.D. Professor of Psychology Chair, Department of Psychology St. Ambrose University Davenport, Iowa 52803 phone: 563-333-6482 e-mail: [email protected] --- To make changes to your subscription contact: Bill Southerly ([email protected]) --- To make changes to your subscription contact: Bill Southerly ([email protected]) --- To make changes to your subscription contact: Bill Southerly ([email protected])
