We investigated effects of coffee cue presentation on desire for coffee and cognitive performance. The 2 (cue and no-cue)×2 (instruction: reward and no-reward) between-subjects design was used. The smell and sight of coffee were presented in the cue condition, but not in the no-cue condition. The participants in the reward condition were instructed that they would obtain coffee after the behavioral task and the amount of coffee depended on their performance of the task. The participants in the no-reward condition were instructed to perform as many tasks as possible. The dependent variable was performance of the behavioral task and subjective desire for coffee. In the task, the participants were asked to find vowels among letters printed on task sheets. As a result, the participants in the cue condition found more vowels than those in the no-cue condition, in both instruction conditions. There was no difference in subjective rating between any conditions. These results suggest that the coffee cue may enhance cognitive performance rather than desire for coffee.

In this paper, I tried to confirm the usefulness of a "lie-detector" electrical kit as a tool for quantitative analysis of the electrodermal activity (EDA) in the educational situation of elementary level of the experimental psychology. Participants (n=21) were divided into one of three groups (low (L)-, middle (M)-, or high (H)- anxiety group) based on the points of the Anthrophobic Tendency Scale (ATS) by Horii and Ogawa (1998). They were exposed to twelve times of auditory stimuli (1 kHz pure tone, 1s) and the EDA was measured by a modified "lie-detector" electrical kit, "Makoto-kun". Although the skin conductance response (SCR) of H group was higher than the other groups, the difference did not reach significant level. On the other hand, the skin conductance level (SCL) gradually increased in H group but decreased in L group following repeated exposure to the auditory stimuli and the difference between these groups were significant. The SCL in M group was intermediate level throughout the exposure to the stimuli. These findings suggest that SCL linearly correlate with the points of ATS. Our findings are consistent with a previous study (Lader and Wing, 1964) showing that the habituation rate of SCL in the patients of anxiety is slower than normal control. In conclusion, the usefulness of our system as a tool for quantitative analysis of the EDA was partly confirmed

We investigated the effect of a post-training chronic infusion of <i>N</i>-methyl-<span style="font-variant: small-caps;">d</span>-aspartate (NMDA) receptor blocker on retention of spatial reference memory in rats. In Experiment 1, we trained 4 groups of rats for 4 days (4 trials/day) in the Morris water maze task. In a single probe trial after retention intervals of 1, 7, 14, and 28 days, the 1-day group showed more goal crossings than shown by the other 3 groups. In Experiment 2, a chronic infusion of the NMDA receptor antagonist <span style="font-variant: small-caps;">d</span>-2-amino-5-phosphonovaleric acid (<span style="font-variant: small-caps;">d</span>-AP5) or a control vehicle into the lateral ventricle was initiated 1 day after the training session, and continued for 6 days. In the subsequent probe trial (7 days after training), the rats that had received the <span style="font-variant: small-caps;">d</span>-AP5 infusion showed significantly more goal crossings than the controls. These findings suggest that an NMDA receptor blockade following acquisition facilitates retention of spatial reference memory.
