Discriminating two brain regions that have been shown to respond to uncertain outcomes
Prior research links greater activation of posterior medial frontal cortex (pMFC) and anterior insula (AI) with decreasing outcome predictability during decision making, as measured by decreasing probability for the more likely outcome out of two or increasing outcome variance. In addition to predictability…
Brain differences in how obsessive-compulsive patients process uncertainty compared to controls
Obsessive-compulsive disorder (OCD) is associated with pathological uncertainty regarding whether an action has been performed correctly or whether a bad outcome will occur, leading to compulsive ‘‘evidence gathering’’ behaviors aimed at reducing uncertainty. The current study used…
A call to take a population approach to neuroscience
We describe and promote a perspective—population neuroscience—that leverages interdisciplinary expertise to (i) emphasize the importance of sampling to more clearly define the relevant populations and sampling strategies needed when using neuroscience methods to address such questions; and (ii) deepen understanding of mechanisms within population science by providing insight regarding underlying neural mechanisms.
How do emotions help us learn and decide?
We developed a new paradigm where participants learn risky contingencies and then make decisions based on what they learned, all while in an MRI machine so BOLD can be measured along with the behavioral data. We find that affective processes play an important role in shaping subjective value in decision making as well as learning.
A thought paper on the role of decision neuroscience in understanding consumer decision making
This paper summarizes a four day workshop where the twelve co-authors discussed the future of decision neuroscience. We outline some initial contributions and point to some research directions. It was an engaging workshop with lots of new ideas.
Decisions to delay outcomes: The brain, subjective value and impulsivity
This study uses fMRI and a delay discounting task to examine the role of impulsivity in how we make decisions about getting something sooner versus something better later.
The value of brain imaging in psychological research
We discuss the role of brain imaging techniques in psychological research, reviewing both the promise and the hype.
How does the brain facilitate rumination and what is the relation to depression?
This paper compares how depressed and healthy controls differ in their ability to forget information, particularly negative information, which may be a precursor for psychological processes such as rumination. We present a new approach to fMRI data analysis that focuses on spatial variability in activation. We find that participants with major depressive disorder show more spatially variable activation in the inferior frontal gyrus compared to healthy control participants using a directed-forgetting task.
Neural correlations of uncertainty and underconfidence
An fMRI study examining underconfidence in the context of Bayesian updating.
Functional localizers in fMRI
We present two experiments and a literature review that explore whether face localizer tasks yield differential localization in the fusiform gyrus as a function of task and contrasting stimuli.
