After more than 30 years since its inception, the utility of brain imaging for understanding and diagnosing mental illnesses is in doubt, receiving well-grounded criticisms from clinical practitioners. Symptom-based correlational approaches have struggled to provide psychiatry with reliable brain-imaging metrics. However, emergence computational has paved a new path not only psychopathology illness but also practical tools practice terms metrics, specifically phenotypes. these phenotypes still lack sufficient test–retest reliability. In this review, we describe recent works revealing that mind brain-related show structural (not random) variation over time, longitudinal changes. Furthermore, findings suggest causes changes will improve construct validity an ensuing increase We propose active inference framework offers general-purpose approach causally by incorporating as observations within partially observable Markov decision processes.

Metacognitive biases have been repeatedly associated with transdiagnostic psychiatric dimensions of 'anxious-depression' and 'compulsivity intrusive thought', cross-sectionally. To progress our understanding the underlying neurocognitive mechanisms, new methods are required to measure metacognition remotely, within individuals over time. We developed a gamified smartphone task designed visuo-perceptual metacognitive (confidence) bias investigated its psychometric properties across two studies (N = 3410 unpaid citizen scientists, N 52 paid participants). assessed convergent validity, split-half test-retest reliability, identified minimum number trials capture clinical correlates. Convergent validity was moderate (r(50) 0.64, p < 0.001) it demonstrated excellent reliability 0.91, 0.001). Anxious-depression decreased confidence (β - 0.23, SE 0.02, 0.001), while compulsivity thought greater 0.07, The associations between psychiatry evident in as few 40 trials. decision-making stable sessions, exhibiting very high for 100-trial (ICC 0.86, 110) 40-trial 120) versions Meta Mind.

Abstract Learning allows humans and other animals to make predictions about the environment that facilitate adaptive behavior. Casting learning as predictive inference can shed light on normative cognitive mechanisms improve under uncertainty. Drawing models, we illustrate how should be adjusted different sources of uncertainty, including perceptual risk, uncertainty due environmental changes. Such models explain many hallmarks human in terms specific statistical considerations come into play when updating However, also display systematic biases deviate from studied computational psychiatry. Some explained conditioned inaccurate prior assumptions environment, while others reflect approximations Bayesian aimed at reducing demands.

Internal states like motivation fluctuate substantially over time. However, studies of the neurocomputational mechanims motivated behavior have failed to capture this. Here, we examined how naturalistic ups and downs in state influence subjective value reward effort. In a microlongitudinal design (N = 155, timepoints 3,344, decision-making tasks 845), captured fluctuations effort-based using smartphone-based momentary assessments as people went about their daily lives. We found that both trait independent multiplicative effects on decision-making. State–behavior coupling was particularly pronounced individuals with higher apathy, meaning choices were even more dependent. Using computational modeling, demonstrate prospectively boosted sensitivity, making willing exert effort future. Our results show day-to-day cognition are tightly linked critical for understanding fundamental human behaviors mental ill-health.

Abstract Traditional psychological research has often treated inter-subject variability as statistical noise (even, nuisance variance), focusing instead on averages rather than individual differences. This approach limited our understanding of the substantial heterogeneity observed in neuropsychiatric disorders, particularly autism spectrum disorder (ASD). In this introduction to a special issue theme, we discuss recent advances cognitive computational neuroscience that can lead more systematic notion core symptom dimensions differentiate between ASD subtypes. These include large participant databases and data-sharing initiatives increase sample sizes autistic individuals across wider range cultural socioeconomic backgrounds. Our perspective helps build bridges symptomatology differences traits non-autistic population introduces finer-grained dynamic methods capture behavioral dynamics at level. We specifically focus how models have emerged powerful tools better characterize general population, with respect social decision-making. finally outline combine harness these advances, one hand, big data initiatives, other models, achieve nuanced improved diagnostic accuracy personalized interventions.

The doctor–patient relationship has received widespread attention as a significant global issue affecting people’s livelihoods. In clinical practice within the medical field, applying existing artificial intelligence (AI) technology presents issues such uncontrollability, inconsistency, and lack of self-explanation capabilities, even raising concerns about ethics morality. To address problem interaction differences arising from diagnosis treatment, we collected textual content dialogues in outpatient clinics local first-class hospitals. We utilized case scenario analysis, starting two specific cases: multi-patient visits with same doctor multi-doctor patient. By capturing external interactions internal thought processes, unify expressions subjective cognition into between data, information, knowledge, wisdom, purpose (DIKWP) models. propose DIKWP semantic model for on both sides, including cognitive model, to achieve transparency throughout entire process. semantically–bidirectionally map diagnostic discrepancy space uncertainty utilize purpose-driven fusion transformation technique disambiguate problem.

Active reinforcement learning enables dynamic prediction and control, where one should not only maximize rewards but also minimize costs such as of inference, decisions, actions, time. For an embodied agent a human, decisions are shaped by physical aspects actions. Beyond the effects reward outcomes on processes, to what extent can modeling behavior in reinforcement-learning task be complicated other sources variance sequential action choices? What bias (for actions per se) hysteresis determined history chosen previously? The present study addressed these questions with incremental assembly models for choice data from hierarchical structure additional complexity learning.

Perceptual uncertainty and salience both impact decision-making, but how these factors precisely trial-and-error reinforcement learning is not well understood. Here, we test the hypotheses that (H1) perceptual modulates reward-based (H2) economic decision-making driven by value of sensory information. For this, combined computational modeling with a uncertainty-augmented reward-learning task in human behavioral experiment ( N = 98). In line our hypotheses, found subjects regulated behavior response to which they could distinguish choice options based on information (belief state), addition errors made predicting outcomes. Moreover, considered combination expected values for decision-making. Taken together, this shows are closely intertwined share common basis real world.

Pavlovian influences impair instrumental learning. It is easier to learn approach reward-predictive signals and avoid punishment-predictive cues than their contrary. Whether the interindividual variability in this influence consistent across time has been examined by a number of recent studies met with mixed results. Here we introduce an open-source, web-based instance well-established Go-NoGo paradigm for measuring influence. We closely replicated previous laboratory-based Moreover, differences were two-week window at level (i) raw measures learning (i.e. performance accuracy), (ii) linear, descriptive estimates bias (test-retest reliability: 0.40), (iii) parameters obtained from reinforcement model fitting selection 0.25).
