As a social species, correct emotional perception is so vital, that the human brain has evolved a mechanism to control attentional choices by exerting a narrowed field of perception during danger, called the scope of attention (SoA). The SoA determines what information will be focused on or ignored by blocking the perception of non-relevant items and increasing selective focus on danger; even if danger is merely a sad-face. The emotional items blocked from perception cannot be remembered because they were never perceived. But, attention-control to emotional stimuli also varies with mood, as seen in mood-disorders. A mood-disorder’s effect upon the …

Substantial evidence has shown that dopamine (DA), particularly in the nucleus accumbens (NAc), is involved in behavioral activation and effort-related processes, such as overcoming work related response costs. Interference with accumbens DA transmission through administration of the vesicular monoamine transportor-2 (VMAT-2) inhibitor tetrabenazine (TBZ) produces an alteration of response allocation in the concurrent FR5/chow choice procedure, biasing animals toward the lower effort alternative. It has been suggested that these drug-induced shifts in effort-related choice behavior seen in rodents are analogous to symptoms such as psychomotor retardation, anergia, and fatigue, which can be observed in people with depression and other related …
