The researchers found that participants were less productive when they'd viewed pleasant outdoor photographs.
To examine this issue, human subjects viewed pleasant, unpleasant, and neutral images during a force production task.
To address this issue, we designed a task in which subjects viewed pleasant, unpleasant, and neutral images during a force production task.
Nineteen in-patients and 19 balanced healthy controls passed MEG measurement while passively viewing pleasant, unpleasant and neutral pictures.
Lack of response to re-view pleasant stimuli significantly predicted higher subsequent cannabis self-administration in patients but not controls, after controlling for degree of prior exposure to cannabis.
SSD patients were significantly less likely than controls to exert effort to try to re-view pleasant stimuli but were not significantly less likely to work to avoid unpleasant stimuli.
Specifically, lonely individuals show weaker activation in the ventral striatum when viewing pictures of pleasant social events than when viewing pleasant pictures of nonsocial objects, whereas this pattern is reversed for nonlonely individuals.
First, N2 (N150) amplitude was greater (more negative) when viewing unpleasant than pleasant pictures, whereas P2 (P260) amplitude was smaller (less positive) when viewing pleasant than neutral pictures (Kenntner-Mabiala & Pauli, 2005).
Electrical pain is highest while viewing unpleasant pictures and lowest while viewing pleasant pictures (Kenntner-Mabiala, Andreatta, Wieser, Muhlberger, & Pauli, 2008; Kenntner-Mabiala & Pauli, 2005; Mini, Rau, Montoya, Palomba, & Birbaumer, 1995).
Dopaminergic neurons within the nucleus accumbens play a critical role in reward processing, and past work finds evidence for this brain region's engagement when participants view pleasant or reinforcing visual stimuli 31, 32 or listen to music.
Similarly, a recent cluster-randomized trial aimed at changing cognitive function among older adults and involving either cycling on a stationary cycle ergometer in a sterile environment or in a virtual-reality enhanced environment (ie, viewing pleasant landscapes and scenery) illustrates the powerful contribution of environmental stimuli to cognitive health.
