“…In other words, relative to an agent with a veridical estimate of average reward, optimistic agents come to expect reward even when they objectively should not. In mania, this is consistent with clinical intuition and the empirical literature (Alloy et al, 2016; Kwan et al, 2020). Note that rational inattention does not predict faster learning (e.g., the trial-to-trial change in expectation) from positive feedback under an optimistic prior, only that the value function is initialized optimistically.…”

Psychopathology is vast and diverse. Across distinct disease states, individuals exhibit symptoms that appear counter to the standard view of rationality (expected utility maximization). We argue that some aspects of psychopathology can be described as resource-rational, reflecting a rational trade-off between reward and cognitive resources. We review work on two theories of this kind: rational inattention, where a capacity limit applies to perceptual channels, and policy compression, where the capacity limit applies to action channels. We show how these theories can parsimoniously explain many forms of psychopathology, including affective, primary psychotic, and neurodevelopmental disorders, as well as many effects of psychoactive medications on these disorders. While there are important disorder-specific differences and the theories are by no means universal, we argue that resource rationality offers a useful new perspective on psychopathology. By emphasizing the role of cognitive resource constraints, this approach offers a more inclusive picture of rationality. Some aspects of psychopathology may reflect rational trade-offs rather than the breakdown of rationality.

“…The present study only examined crosssectional associations between psychological factors and clinical outcomes. However, prospectively, both impulsivity and BAS processes have been found to predict time to onset of (hypo)manic episodes or symptom intensification (Alloy et al, 2008;Alloy et al, 2009b;Kwan et al, 2020;Meyer et al, 2001a;Swann et al, 2009).…”

“…In Gray's theory, a psychobiological trait, called sensitivity to reward or reward sensitivity, reflects the functional outcomes of the activity in the BAS (Gray, 1994). Growing evidence suggests that in particular reward sensitivity is associated with important behavioural choices that have major implications to health, such as excessive consumption of palatable foods and use of addictive substances (Emery and Simons, 2017;Joyner et al, 2019;Tatnell et al, 2019); it has also been found to predict recurrence of manic episodes in bipolar disorder (Kwan et al, 2020). In contrast, low reward sensitivity can predict symptoms of depression (Hausman et al, 2018).…”

Objective: Reward sensitivity is an increasingly used construct in psychiatry, yet its possible inner structure and relationship with other affective variables are not well known. Methods: A reward sensitivity measurement scale was constructed on the basis of large item pool collected from birth cohort representative samples (the Estonian Children Personality Behaviour and Health Study; original n = 1238). Affective Neuroscience Personality Scale (ANPS) and the Adult Attention deficit hyperactivity disorder (ADHD) Self-Report Scale (ASRS) were administered in young adulthood. A variant (rs4570625) of the gene encoding tryptophan hydroxylase 2 (TPH2) that is responsible for the synthesis of central serotonin was genotyped. Results: Reward sensitivity consisted of two orthogonal components, operationally defined as Openness to Rewards and Insatiability by Reward, that respectively characterise the striving towards multiple rewards and the strong pursuit and fixation to a particular reward. While SEEKING and PLAY (and to lower extent CARE) of the ANPS co-varied with Openness to Rewards, FEAR, SADNESS, and ANGER were related to Insatiability by Reward. The total score of ASRS was moderately correlated with Insatiability by Reward, while the association with Openness to Rewards was negligible. However, ASRS Inattention had some negative relationship with the Social Experience facet of Openness to Rewards. The T/T homozygotes for the TPH2 promoter polymorphism had lower Insatiability by Reward but not Openness to Rewards. Conclusions: Behaviours sensitive to rewards are separable to the components of variability and fixation, and these components are differentially related to affective aspects of personality, attention, and hyperactivity as well as to TPH2 genotype.
