Beschreibung:
Three forms of nonassociative learning (habituation, dishabituation, and sensitization) have commonly been explained by a dual-process view in which a single decrementing process produces habituation and a single facilitatory process produces both dishabituation and sensitization. A key prediction of this view is that dishabituation and sensitization should always occur together. However, we show that dishabituation and sensitization, as well as an additional process, inhibition, can be behaviorally dissociated in Aplysia by (i) their differential time of onset, (ii) their differential sensitivity to stimulus intensity, and (iii) their differential emergence during development. A simple dual-process view cannot explain these results; rather, a multiprocess view appears necessary to account for nonassociative learning in Aplysia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marcus, E A -- Nolen, T G -- Rankin, C H -- Carew, T J -- 5-F32-NS-07480/NS/NINDS NIH HHS/ -- MH41083/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1988 Jul 8;241(4862):210-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Yale University, New Haven, CT 06520.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3388032" target="_blank"〉PubMed〈/a〉
