TL;DR: It is suggested that pathological gambling was a heterogeneous disorder in terms of loss aversion, which means that a loss is subjectively felt to be larger than the same amount of gain, and might be useful for understanding cognitive and neurobiological mechanisms and the establishment of treatment strategies for PG.

TL;DR: It is found that individuals who tend to adhere to social rules and regulations (who are high in measured agreeableness and conscientiousness) are more susceptible to the sunk cost effect.

TL;DR: It is suggested that insular activation during reward anticipation may serve as a marker of progression of pathological gambling.

TL;DR: The study suggests that the heterogeneity of GD is underpinned at the brain structural level, which might be useful for understanding neurobiological mechanisms and for the establishment of precise treatment strategies for GD.

TL;DR: The results suggest that ambiguity aversion, a well-established subjective bias, is attenuated in patients with schizophrenia, highlighting the need to distinguish between risk and ambiguity when assessing decision-making under these situations.
