Humans expect positive events in the future even when there is no evidence to support such expectations. For example, people expect to live longer and be healthier than average, they underestimate their likelihood of getting a divorce, and overestimate their prospects for success on the job market. We examined how the brain generates this pervasive optimism bias. Here we report that this tendency was related specifically to enhanced activation in the amygdala and in the rostral anterior… Expand
The link between optimism bias and attention bias: A neurocognitive perspective
TLDR
It is suggested that optimism bias and reward-related attention bias mutually enforce each other and recruit a common underlying neural network and it is further postulate that biased memory processes influence the interplay of optimism and Reward- related attention bias. Expand
The Neural Substrate of Positive Bias in Spontaneous Emotional Processing
TLDR
The findings suggest that spontaneous positive cognitive emotion regulation in health may result from processes that, while actively suppressing emotionally salient information, differ from those associated with effortful and directed control. Expand
Dissociable roles of ventromedial prefrontal cortex (vmPFC) and rostral anterior cingulate cortex (rACC) in value representation and optimistic bias
TLDR
The neural basis of OB is examined in healthy individuals during probability estimation of future positive and negative events occurring to themselves relative to other, comparable individuals and there was no significant relationship between responsiveness within these regions and self reports of depression symptoms. Expand
Social optimism biases are associated with cortical thickness
TLDR
A defensive self-enhancement dimension was identified that associated significantly and reliably with the cortical thickness of the insula and inferior frontal cortex and included unfavorable biases toward unpopular out-groups and indicators of personal optimism and pessimism. Expand
Neural correlates of ‘pessimistic’ attitude in depression
TLDR
Brain activation in depression during expecting events of unknown emotional valence was comparable with activation while expecting certainly negative, but not positive events, consistent with cognitive models supposing that depressed patients develop a ‘pessimistic’ attitude towards events with an unknown emotional meaning. Expand
The Neural Basis of Always Looking on the Bright Side
Humans generally exhibit a pervasive future bias in favour of optimism. We overestimate the likelihood of success in work, relationships and fi nancial investments. Similarly, we underestimate theExpand
Anterior Cingulate Activation Is Related to a Positivity Bias and Emotional Stability in Successful Aging
TLDR
The finding of a resource-dependency of this positivity effect suggests demanding self-regulating processes that are related to emotional well-being, and how the brain might mediate the tendency to preferentially engage in positive information processing in healthy aging is highlighted. Expand
Well-being and Anticipation for Future Positive Events: Evidences from an fMRI Study
TLDR
The results showed that bilateral medial prefrontal cortex (MPFC) were activated during anticipation for positive events relative to neutral events, and the enhanced brain activation in MPFC was associated with higher level of well-being, suggesting a neural mechanism by which the anticipation process to future desired events correlates to human well- being.

Where expectation meets attention: the dynamic interplay between optimism bias and attention bias
Optimism bias and positive attention bias are crucial components of healthy information processing. Even though recent theories (e.g., the combined cognitive biases hypothesis) suggest that differentExpand

TLDR
A new study has shown that optimism bias is increased by up-regulating dopaminergic function via dihydroxy-l-phenylalanine (l-DOPA) as belief updating for bad news becomes impaired, and proposes that this process occurs as l-Dopa attenuates belief updating in response to bad news about the future.

Illusion and well-being: a social psychological perspective on mental health.
TLDR
Research suggesting that certain illusions may be adaptive for mental health and well-being is reviewed, examining evidence that a set of interrelated positive illusions—namely, unrealistically positive self-evaluations, exaggerated perceptions of control or mastery, and unrealistic optimism—can serve a wide variety of cognitive, affective, and social functions. Expand
Unrealistic optimism about future life events
Two studies investigated the tendency of people to be unrealistically optimistic about future life events. In Study 1, 258 college students estimated how much their own chances of experiencing 42Expand
Neural correlates of evaluation associated with promotion and prevention regulatory focus
TLDR
To examine the interaction of motivation and cognition, participants made good/bad or abstract/concrete judgments about concepts during fMRI scanning and the results are consistent with the hypothesis that the way in which evaluative information is processed is influenced by individual differences in self-regulatory focus. Expand
Neuroanatomical Evidence for Distinct Cognitive and Affective Components of Self
TLDR
It is found that distinct neural circuits in adjacent regions of the prefrontal cortex subserve cognitive and emotional aspects of self-reflection, and the medial prefrontal cortex responded only to material that was self-descriptive, and this did not differ as a function of the valence of the trait. Expand
Cognitive and emotional influences in anterior cingulate cortex
TLDR
Various findings are reviewed in relation to the idea that ACC is a part of a circuit involved in a form of attention that serves to regulate both cognitive and emotional processing, and how the success of this regulation in controlling responses might be correlated with cingulate size. Expand
Emotion-induced changes in human medial prefrontal cortex: II. During anticipatory anxiety.
TLDR
Regional cerebral blood flow was examined in the human medial prefrontal cortex with positron emission tomography during anticipatory anxiety and changes in MPFC and in the midbrain were correlated with each other and with anxiety self rating. Expand
Thinking of the future and past: the roles of the frontal pole and the medial temporal lobes
TLDR
The present results suggest that thinking of the future is closely related to retrospective memory, but that specific areas in the frontal pole and the medial temporal lobes are more involved with thinking ofThe future than that of the past. Expand
Ventromedial prefrontal cortex activation is critical for preference judgments
TLDR
The medial frontal gyrus was significantly more activated during the preference judgment trials, relative to visual discrimination trials, which is consistent with the role of the ventromedial prefrontal cortex in the representation of complex appetitive states. Expand
Extinction Learning in Humans Role of the Amygdala and vmPFC
TLDR
The neural mechanisms of fear extinction in humans are explored and activation in the vmPFC was primarily linked to the expression of fear learning during a delayed test of extinction, indicating that the mechanisms of extinction learning may be preserved across species. Expand
Remembering the past and imagining the future: Common and distinct neural substrates during event construction and elaboration
TLDR
A striking neural overlap in regions comprising the autobiographical memory retrieval network is consistent with findings that amnesic patients exhibit deficits in both past and future thinking, and confirms that the episodic system contributes importantly to imagining the future. Expand
