Abstract: The capacity of human observers to remember incidentally learned olfactory sensations as a function of theirperceived pleasure/ displeasure was investigated. In the encoding phase of the experiment, the participants rateda sequence of 24 stimuli for (i) sensory intensity, and (ii) degree of pleasure or displeasure. They were then giventwo successive explicit memory tests, (i) free recall of the names of encountered odors, and (ii) yes/norecognition of the encountered odor stimuli. The results showed higher recall and recognition accuracy for thestimuli that had been rated higher in affective content at the time of study. These results support the hypothesisthat hedonicity is a variable that influences the encoding and storage of events in memory.
