Neurocognitive Modeling of Perceptual Decision Making
Mathematical psychology and systems neuroscience have converged on stochastic accumulator models to explain decision making. We examined saccade decisions in monkeys while neurophysiological recordings were made within their frontal eye field. Accumulator models were tested on how well they fit response probabilities and distributions of response times to make saccades. We connected these model...
متن کاملNeurocognitive performance of methamphetamine users discordant for history of marijuana exposure.
Abuse of the stimulant drug methamphetamine is associated with neural injury and neuropsychological (NP) deficits, while the residual effects of marijuana use remain uncertain. We sought to determine if methamphetamine dependent persons who also met criteria for marijuana abuse or dependence evidenced different NP performance than those with dependence for methamphetamine alone. We examined thr...

متن کاملDecision Making Processes and Outcomes
The primary aim of this study was to examine the contributions of individual characteristics and strategic processing to the prediction of decision quality. Data were provided by 176 adults, ages 18 to 93 years, who completed computerized decision-making vignettes and a battery of demographic and cognitive measures. We examined the relations among age, domain-specific experience, working memory...
متن کاملOn a triadic neurocognitive approach of decision-making to addiction
Paradoxical behaviours characterizing an addiction could be understood as the result of a combination between an attempt to cope with dominant painful feelings (e.g., anxiety with low self-esteem) and sub-optimal decision-making prioritizing short-term over long-term consequences. This article focused on decision-making and emphasized that addicts’ decisions are determined by immediate outcomes...
