In Experiment one 7 Brushtail possums were trained, using food, to perform a Delayed-Matching-To-Sample procedure using still and flickering light stimuli, over a 0, 1 and 2 second delay. A criterion of 80 percent correct for 5 consecutive days was set for the requirement to probe test. Probe session delays were 0, 0.5, 1, 2, 4, and 8 seconds. Performance was analysed using the measure of discrimination log d. Log d = 1 at the possums training delay and dropped back to log d = 0 at the longer inexperienced delays. The possums performance at this task was only adequate, so in case the stimuli were causing discrimination difficulties they were changed for the following experiment to horizontal and vertical light stimuli. Experiment two used the horizontal and vertical light stimuli to further test DMTS in possums. The possum's responding stayed at 50 percent correct, or chance, so the task was changed to a Simultaneous-Choice procedure. However, this did not have any effect on improving their results with responding accuracy remaining at 50 percent correct. Experiment three involved a conditional discrimination procedure, which was implemented to find out whether the possums could in fact discriminate between a horizontal and vertical light. All the possums in this experiment reached 80 percent correct overall and at responding to either a horizontal or vertical light. These results are enough to conclude that it was not the stimuli used in the previous two experiments which that had been causing the difficulties but the task itself. It is not known exactly why the possums were so unsuccessful in performing a DMTS or MTS task. More research into DMTS in possums in greatly needed and would offer a better understanding of the results of this study.

The purpose of this study was to investigate the effects of two imaginal methods on a short-term memory task. A previously unresearched technique, Personalistic (P) mental imagery was combined with Interactive (I) imagery to form Personal-Interactive (P-I) mental imagery. Subjects in the P-I group were instructed to visualize themselves personally involved in an interactive scene of three given nouns. The effects of this group were compared to the effects of I imagery on a short-term memory task requiring free recall of 22 noun triads. A t test analysis found no significant difference between the I and P-I groups on total number of words correctly recalled and total number of failures to generate an image. It was concluded that the added dimension of P to I imagery did not produce greater recall than I imagery independently. It was recommended that P mental imagery be tested independently on a recall task of one word or item as opposed to two or more.
