After controlling for demographics, increasing memory complaint (MCS) was significantly associated with more depressive symptoms on GDS (β 0.29, P<0.005).
Such an increase is not surprising as there is some behavioral generalization from the learned odor to the new odor, and increasing memory for the learned odor through caffeine treatment may increase generalization responses to the novel odor [ 34].
Overall, correct response rate decreased with increasing memory load for both control and ADT participants.
Thus, both cues and outcomes were better remembered in a predictable situation; for cues, this effect was specifically due to increased memory for reward-predicting cues.
A meta-analysis across these experiments indicated that, among the female participants and with 95% confidence, 5 minutes of post-learning exercise increased memory for paired association by 0.40 to 4.63 items.
LC stimulation immediately prior to a learning episode also selectively increases memory for the spatial aspects of that episode.
Note that L-DOPA tended to increase memory for the information provided [F 1,20) = 3.67, p = 0.07], an effect that reached significance for desirable information only [desirable: t(20) = 2.12, p < 0.05; undesirable: t(20) = 1.2, p > 0.1], although there was no interaction [F 1,20) = 0.46, p > 0.5; Figure 3].
An optimism bias can in principle be generated via a number of different mechanisms [ 5, 12, 23], and it is possible that serotonin could impact on expectations by altering other processes, such as mental simulation of future events [ 23] or increased memory for positive emotions [ 24].
Schisandra chinensis belongs to the Schisandraceae family and it has traditionally been used as a refreshment, an antitussive, a tranquillizer, and a treatment for insomnia and fatigue, to increase memory function, and as a sedative [ 153].
The primary reasons of the slight performance drop in the right end of the plots is due to the fact that more virtual cores (i.e., hyperthread contexts) than physical core are used and the increased memory traffic for high numbers of trajectories.
