Abstract
A HURDLE-CROSS RESPONSE WAS EMPLOYED TO ASSESS THE 1-TRIAL LEARNING PERFORMANCE OF MICE, 9-10 WK. OF AGE. THE MEDIAN RESPONSE LATENCY OF THE 1ST TRIAL WAS 29 SEC. FOODAND WATER DEPRIVATION FOR UP TO 9 HR. DID NOT SIGNIFICANTLY ALTER RESPONSE LATENCY. FOOT-SHOCK INTENSITY, RATHER THAN DURATION, WAS THE MORE IMPORTANT VARIABLE AFFECTING THE 2ND TRIAL LATENCY. RESPONSE LATENCIES INCREASED LINEARLY AS A FUNCTION OF THE SHOCK INTENSITY, INDICATING A CHANGE IN THE QUALITY AND INTENSITY OF RECALL. THE HYPOTHESIS PRESENTED ASSUMED THE REGISTRATION AND PERMANENT STORAGE OF THE MEMORY TRACE TO TAKE PLACE AS AN EARLY EVENT FOLLOWED BY A PHASE WHICH DETERMINES THE LATENCY OR EMOTIONALITY OF THE RESPONSE MEASURED.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
