People tend to remain overly optimistic even when faced with information about a gloomy future. A study now shows that people are selectively worse at incorporating information about a worse-than-expected future. It also describes the learning signals in the brain that correlate with this bias. 
More Realistic Forecasting of Future Life Events After Psilocybin for Treatment-Resistant Depression
TLDR
It is suggested that psilocybin with psychological support might correct pessimism biases in patients with treatment-resistant depression, enabling a more positive and accurate outlook.

The author argues that in its focus on finding positive outcomes, bereavement research has neglected or denigrated central phenomena in intense and long-term grief: sorrow and solace. Sorrow has two
The Preholiday Corporate Announcement Effect
We find that investors react more favorably to corporate announcements of share repurchases, SEOs, earnings, dividend changes, and acquisitions if the announcement is made immediately prior to or on
Control-Related Motivations and Information Security Policy Compliance: The Role of Autonomy and Efficacy
Abstract Employees' failures to follow information security policy can be costly to organizations, causing organizations to implement security controls to motivate secure behavior. Information
Psychosocial assessment of living kidney donors: What implications have temperament and character for decision-making?
TLDR
The personality of kidney donor candidates to non-donor controls is compared and the personality profile of candidates psychosocially at risk is analyzed to ensure a free-willed decision.

How unrealistic optimism is maintained in the face of reality
TLDR
Findings indicate that optimism is tied to a selective update failure and diminished neural coding of undesirable information regarding the future.
Neural mechanisms mediating optimism bias
TLDR
How the brain generates this pervasive optimism bias was related specifically to enhanced activation in the amygdala and in the rostral anterior cingulate cortex when imagining positive future events relative to negative ones, suggesting a key role for areas involved in monitoring emotional salience in mediating the optimism bias.
Self-Control in Decision-Making Involves Modulation of the vmPFC Valuation System
TLDR
Two hypotheses about the neurobiology of self-control are proposed: (i) Goal-directed decisions have their basis in a common value signal encoded in ventromedial prefrontal cortex (vmPFC), and (ii) exercising self- control involves the modulation of this value signal by dorsolateral cortex (DLPFC).
Inhibition-related Activation in the Right Inferior Frontal Gyrus in the Absence of Inhibitory Cues
TLDR
It is concluded that rIFG involvement in stopping is consistent with a role in reprogramming of action plans, which may comprise inhibition, and its activity can be triggered through automatic, bottom–up processing.
States versus Rewards: Dissociable Neural Prediction Error Signals Underlying Model-Based and Model-Free Reinforcement Learning
TLDR
Using functional magnetic resonance imaging in humans solving a probabilistic Markov decision task, the neural signature of an SPE is found in the intraparietal sulcus and lateral prefrontal cortex, in addition to the previously well-characterized RPE in the ventral striatum, which supports the existence of two unique forms of learning signal in humans.
Neural basis of the undermining effect of monetary reward on intrinsic motivation
TLDR
The results show that performance-based monetary reward indeed undermines intrinsic motivation, as assessed by the number of voluntary engagements in the task, and that activity in the anterior striatum and the prefrontal areas decreased along with this behavioral undermining effect.
Depression and pessimism for the future: biased use of statistically relevant information in predictions for self versus others.
TLDR
The results provided strong support for pessimism on the part of depressed individuals relative to nondepressed individuals in forecasts for both self and others, and in line with the attributional-style hypothesis.
Marketing actions can modulate neural representations of experienced pleasantness
TLDR
Evidence is provided for the ability of marketing actions to modulate neural correlates of experienced pleasantness and for the mechanisms through which the effect operates.
The Adapted mind : evolutionary psychology and the generation of culture
Although researchers have long been aware that the species-typical architecture of the human mind is the product of our evolutionary history, it has only been in the last three decades that advances
A quantitative meta-analysis of fMRI studies in bipolar disorder.
TLDR
Patients with bipolar disorder underactivated the inferior frontal cortex (IFG) and putamen and overactivated limbic areas, including medial temporal structures (parahippocampal gyrus, hippocampus, and amygdala) and basal ganglia, and enhanced limbic activation was elicited by emotional and not cognitive tasks, and not clearly related to mood states.
