Background: It is well known that individuals with schizophrenia have dopaminergic abnormalities as well as memory-related difficulties, both of which are associated with impulsive decision making. We used a delay discounting measure to test the degree to which patients make future-oriented decisions.
Methods: 42 patients with schizophrenia and 29 healthy participants completed a delay discounting measure along with tests of cognitive function and, in patients, symptom ratings.
Results: Patients discounted more steeply than did comparison participants. Discounting among patients related to memory capacity and tended to relate inversely to negative symptoms.
Conclusions: The impulsive decision making evidenced by patients suggests that they may be prone to choosing immediate over long-term rewards, even when their interests are better served by choosing the latter. Improving cognitive function may enhance their ability to make future-oriented decisions.

Background: Intertemporal choices are the process by which people make choices about losses or gains at different points in time (near or far). To explore the relationship between font color and intertemporal choice and to examine the serial mediation of time perception and intradimensional difference comparison on the association between font color and intertemporal choice on the basis of attribute-based choice models.
Methods: We randomly assigned subjects to the intertemporal choices questionnaire in a specific font color (blue vs.
Delay discounting and symptoms of anxiety and depression in adolescents experiencing challenges with managing type 1 diabetes.

We examined if anxiety/depression, delay discounting (DD), and their interaction were associated with greater A1c levels and reduced medical adherence in adolescents with type 1 diabetes (T1D). Sixty-one adolescents with T1D completed a DD task and an A1c blood test. Adherence was assessed by self-monitoring of blood glucose (SMBG) using glucometer data.

Twenty-nine adults with GAD performed the balloon analogue risk-taking task (BART) and delay discounting task (DDT) during five sessions of transcranial direct current stimulation (tDCS) with different stimulation conditions. The stimulation conditions were: anodal dlPFC (F3)/cathodal vmPFC (Fp2), anodal vmPFC (Fp2)/cathodal dlPFC (F3), anodal dlPFC (F3)/cathodal right shoulder, anodal vmPFC (Fp2)/cathodal left shoulder, and sham stimulation.

Background: A preference for sooner-smaller over later-larger rewards, known as delay discounting, is a candidate transdiagnostic marker of waiting impulsivity and a research domain criterion. While abnormal discounting rates have been associated with many psychiatric diagnoses and abnormal brain structure, the underlying neuropsychological processes remain largely unknown. Here, we deconstruct delay discounting into choice and rate processes by testing different computational models and investigate their associations with white matter tracts.

Binge eating (BE) is associated with psychological distress, functional impairment, and elevated risk of eating disorder diagnoses, and BE prevalence is increasing. Motivational and self-regulatory processes such as delay discounting may be important influences on BE; however, evidence is inconclusive, and lacks explanation of mechanisms. This study investigated how food choice motives mediate the pathway from delay discounting (DD) to BE symptomatology.
