Összefoglaló szövege

Introduction: Sensory signals provide ambiguous information about the state of objects in the environment. Thus, our brain has to make perceptual decisions about the environment’s most likely state. Such perceptual decisions are reflected in binocular rivalry, a perceptual phenomenon known to change during development and maturation, and to differ in certain psychopathologies, compared to neurotypicals.

Aims: We aimed to explore how some aspects of perceptual decision making change during development, maturation, and how they differ in certain psychopathologies, using binocular rivalry as a proxy measure.

Method: We measured how children, adolescents, young adults, mature adults, and two psychopathological cohorts - adults with autism spectrum disorder, and with borderline personality disorder - behave in a binocular rivalry task. We then employed a computational model to explore the dynamics underlying binocular rivalry. Using the results of this modeling procedure, we performed simulations to predict each group’s perceptual behaviour in more general conditions.

Results: We find that the observed rivalry statistics differ between groups. In terms of our model, this implies that each group (on average) operates in a particular regime of model parameter space. Functionally, these operating regimes predict different degrees of perceptual sensitivity, variability, and ‘stickiness’ for each group. Our results show a developmental trend from childhood to young adulthood, which regresses in late adulthood; and that each adult clinical group differs from neurotypical adults in specific ways.

Conclusion: We conclude that the dynamics underlying binocular rivalry reflect the development of the visual system that is still active in adolescence, extends to young adulthood, regresses in old age, and shows marked changes in clinical populations. Furthermore, these dynamics predict differences in perceptual decision making between the observed groups.
