“…3. It has been noted that various motor abnormalities are present across a range of psychological and developmental disorders (see Mittal, 2015a, 2015b) and Walther & Morrens (Walther and Morrens, 2015) for discussion). While a detailed review of which motor abnormalities are present to what extent in which disorders is out of the scope of the current review, it is notable that there is appreciable overlap, with some motor abnormalities presenting across multiple disorders.…”

“…Secondly, studies that have shown alternation rates to be elevated even when stimulus valence was neutral all showed this effect in clinical populations (Jia et al, 2015(Jia et al, , 2020Vierck et al, 2013;Xiao et al, 2018). Since in all the studied disorders (generalized anxiety disorder (GAD), major depression, bipolar disorder, schizophrenia) psychomotor, as well as cognitive functions, have been shown to be impaired (Etkin et al, 2022;Walther & Morrens, 2015), this is an important potential confound to be considered. However, Jia et al (2015Jia et al ( , 2020 have included catch trial conditions (trials in which both eyes receive the same input and perceptual alternations thus are the veridical percept), to control for potential behavioural differences of reporting current percepts and have not found significant differences between the groups.…”

Affective States and Traits and Their Influence on Perceptual Stability During Binocular Rivalry

Affective states and traits have been associated with different measures of perceptual stability during binocular rivalry. Diverging approaches to measuring perceptual stability as well as to examination of the role of affective variables (baseline affective state vs. mood induction; clinical vs. sub-clinical expressions of affective traits) have contributed to an inconclusive pattern of findings. Here, we studied the influence of affective traits (depressiveness and trait anxiety) and states (positive, negative and neutral; manipulated with a musical mood induction paradigm) on different measures of perceptual stability (dominance ratios and phase durations) during binocular rivalry. Healthy participants (N=50) reported alternations in a biased perception condition, during which one stimulus was more likely to be perceived than its counterpart (upright vs. tilted face), and in a control condition, in which both stimuli (Gabors of different orientations) were equally likely to be perceived. Baseline positive state affect significantly predicted longer phase durations during neutral viewing conditions, whereas affective traits did not yield any such effect. Furthermore, in an exploratory analysis, induced negative affect attenuated stimulus related bias in predominance ratios. Overall, we found a strong correlation between both measures of perceptual stability (phase durations and dominance ratios). Our findings thus question the distinction between different measures of perceptual stability during binocular rivalry and highlight the role of affective traits in its formation.

Affective states and traits have been associated with different measures of perceptual stability during binocular rivalry. Diverging approaches to measuring perceptual stability as well as to examination of the role of affective variables have contributed to an inconclusive pattern of findings. Here, we studied the influence of affective traits, such as depressiveness and trait anxiety, and states, which were manipulated with a musical mood induction paradigm, on different measures of perceptual stability (dominance ratios and phase durations) during binocular rivalry. Fifty healthy participants reported alternations in two conditions: a biased perception condition with an unequal probability of perceiving stimuli, using an upright versus a tilted face with a neutral expression, and a control condition with equal chances of perceiving stimuli, using Gabors of different orientations. Baseline positive state affect significantly predicted longer phase durations whereas affective traits did not yield any such effect. Furthermore, in an exploratory analysis, induced negative affect attenuated stimulus related bias in predominance ratios. Overall, we found a strong correlation between both measures of perceptual stability (phase durations and dominance ratios). Our findings thus question the distinction between different measures of perceptual stability during binocular rivalry and highlight the role of affective states in its formation.
