Marijuana, he argued, is a particularly insidious drug for adolescents, because it interferes with memory, decreases energy and stunts development of some "psychosocial skills," a key task during the teenage years.
Impaired memory, decreased social interaction and anxiety behavior were also induced by chronic stress.
Recent research has focused on interference resolution deficits as the main cause of short-term memory decreases in aging.
Amongst the series, analogue 13 and 20 are the most promising multi-targeted candidates which can potentially increase memory, decrease free radical levels and protect neurons against cognitive deficit.
Nature is also shown to restore our focus (known as attention restoration theory), our mood, our self-esteem, our memory, decrease aggression, reduce stress, and even reduce pain.
Indeed, we observed main effects of "item type" (F1,17 = 16.01; p<0.001), indicating that memory performance was significantly better for new items than for old items; of "group" (F4,68 = 24.95; p<0.001; ε = 0.726), showing that memory decreased significantly with group; and of "version" (F1,17 = 7.121; p<0.05), because memory performance was worse in the long than in the short version.
The estimated value of ϕ (i.e.,.57; SE = 0.0998) suggested that this memory decreased geometrically by about 50% with the passage of each quarter.
After one year of GH treatment scores on tests measuring verbal short- and long-term memory decreased as IGF-I levels increased.
In contrast, face recognition memory decreased significantly across all retention intervals except between immediate and 4 days testing (Ps < 0.01) [ F 3, 79) = 39.65, P < 0.001].
However for emotional memory, decreased amygdala activity during the memorization of happy and neutral faces after a single dose of progesterone was observed (van Wingen et al., 2007).
When ERN amplitudes increased, the percentage of errors on the Sternberg test of working memory decreased, suggesting that by expanding the working-memory capacity, larger units of information are retained in the system, enabling more effective error detection.
