Experiments
In a quest to produce a simple neuropsychological tool that would adequately assess the obvious deficits in emotional processing, decision-making, and social skills of OMPFC lesioned individuals Bechara et al. 1994 created the Iowa gambling task. Their aim was to produce " task which simulates in real time, personal real-life decision-making relative to the way it factors uncertainty of premises and outcomes, as well as reward and punishment" (p. 8). The task measures a form of learning that has been defined as emotion-based learning. Studies using the gambling task have found deficits in various neurological (e.g. amygdala and OMPFC) and psychiatric populations (e.g. schizophrenia, mania, drug abusers), providing support for the SMH.

Famous quotes containing the word experiments:
“My experiments did not turn out quite like yours, Henry. But science, like love, has her little surprises.”
—William Hurlbut (1883–?)
“Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.”
—James Conant (1893–1978)
“A country survives its legislation. That truth should not comfort the conservative nor depress the radical. For it means that public policy can enlarge its scope and increase its audacity, can try big experiments without trembling too much over the result. This nation could enter upon the most radical experiments and could afford to fail in them.”
—Walter Lippmann (1889–1974)
