“…Indeed, it has been demonstrated that in such situations, healthy subjects tend to perceive illusory patterns, creating regularities where there are none, and providing superstitious or conspiratorial explanations for ambiguous scenarios. 14 These observations resemble the early features of psychosis, including sense of change and feeling of strangeness, 15, 16, 17 search for explanation, 18, 19 apophenia 20 and jumping to conclusions. 21, 22 …”

A state of pathological uncertainty about environmental regularities might represent a key step in the pathway to psychotic illness. Early psychosis can be investigated in healthy volunteers under ketamine, an NMDA receptor antagonist. Here, we explored the effects of ketamine on contingency learning using a placebo-controlled, double-blind, crossover design. During functional magnetic resonance imaging, participants performed an instrumental learning task, in which cue-outcome contingencies were probabilistic and reversed between blocks. Bayesian model comparison indicated that in such an unstable environment, reinforcement learning parameters are downregulated depending on confidence level, an adaptive mechanism that was specifically disrupted by ketamine administration. Drug effects were underpinned by altered neural activity in a fronto-parietal network, which reflected the confidence-based shift to exploitation of learned contingencies. Our findings suggest that an early characteristic of psychosis lies in a persistent doubt that undermines the stabilization of behavioral policy resulting in a failure to exploit regularities in the environment.

“…Abstract sounds were also used to assess abnormal perceptual experiments in schizophrenia (SCZ). Results highlighted ambivalence in familiarity and bizarreness in SCZ that might be due to the coactivation of ecologic and analytic listening in a conflicting way (Micoulaud-Franchi et al, 2012). Finally, in a study on perceived motion of sounds, abstract sounds were used to identify motion categories and propose intuitive control parameters for synthesizing sounds evoking motion (Merer et al, 2011;Merer et al, 2013).…”

This article describes the first part of a study aiming at adapting the mechanical car door construction to the drivers' expectancies in terms of perceived quality of cars deduced from car door sounds. A perceptual cartography of car door sounds is obtained from various listening tests aiming at revealing both ecological and analytical properties linked to evoked car quality. In the first test naive listeners performed absolute evaluations of five ecological properties (i.e., solidity, quality, weight, closure energy, and success of closure). Then experts in the area of automobile doors categorized the sounds according to organic constituents (lock, joints, door panel), in particular whether or not the lock mechanism could be perceived. Further, a sensory panel of naive listeners identified sensory descriptors such as classical descriptors or onomatopoeia that characterize the sounds, hereby providing an analytic description of the sounds. Finally, acoustic descriptors were calculated after decomposition of the signal into a lock and a closure component by the Empirical Mode Decomposition (EMD) method. A statistical relationship between the acoustic descriptors and the perceptual evaluations of the car door sounds could then be obtained through linear regression analysis.

“…First, there is little if any research into if, or how, factors contributing to motivated behaviour relate to aberrant salience. Second, although some evidence has emerged consistent with the aberrant salience hypothesis of schizophrenia (Haralanova, Haralanov, Beraldi, Moller, & Hennig‐Fast, ; Jensen et al, ; Micoulaud‐Franchi et al, ), findings are inconsistent. For example, although increased aberrant salience has been found in schizophrenia (Pankow et al, ) and those at risk of psychosis (Cicero, Kerns, & McCarthy, ), other findings indicate no significant difference compared with unaffected individuals (Ceaser & Barch, ; Roiser et al, ).…”
