Results obtained on a task of learning an obstacle avoidance behaviour for the mobile miniature robot Khepera show that this last implementation is very effective, learning more than 40 times faster than the basic Q-learning implementation.
Note that prefrontal NE depletion did not interfere with either associative or mnemonic processes because, as previously shown, NE-depleted animals proved capable of learning a passive avoidance task [28] and of associating context with drug effects [27].
This suggests that prompting people to deliberate the consequences of learning or avoiding health information -- this cognitive shift can actually reduce avoidance of crucial health information.
In addition, a short-term juvenile exposure to variable stressors produced two types of impaired avoidance learning reminiscent of symptoms of both mood and anxiety disorders [20], [21].
Furthermore, no large effects of learning (measured using Pearson's correlation coefficient) were found in thecollision avoidance manoeuvre.
It is possible that excessive fear of the UCS would interfere with the smooth progression of avoidance learning.
Young adult KINIH mice had a very similar behavioral phenotype to Fmr1 KO mice (Qin et al., 2011), with hyperactivity, reduced anxiety, impaired social interactions, and deficits on passive avoidance test of learning and memory.
Each mouse was placed in the left hand chamber of the two-way shuttle box and the internal gate was closed to allow the mouse to habituate to one chamber for 5 min. All mice were then subject to 100 trials of avoidance learning.
