Abstract
This study tested the influence of mood on the perception of the sitting affordance in two experiments. The objective of Experiment 1 was to evaluate participants' perception of the sitting affordance, without mood induction. Forty-three participants assessed their maximum sitting height (SHmax) from different seat heights (perceptual SHmax) before performing the action (motor SHmax). They accurately perceived the sitting affordance, in body-scaled intrinsic units. Indeed, participants all perceived they could sit as long as the seat height did not exceed 82% (perceptual πc) of their total leg length (L), while the actual value of this intrinsic relationship was 83% (motor πc). In Experiment 2, forty participants were subjected to a mood induction procedure before performing the task employed in Experiment 1. Neutral participants accurately perceived the sitting affordance, as their perceptual πc was equivalent to their motor πc. However, both joyful and sad participants had their perceptual πc significantly lower than their motor πc. These differences between mood groups were not explained by a variation in maximal effective action capabilities. Indeed, participants had equivalent motor πc, whatever their mood. Two interpretations are offered to explain how joyful and sad moods could influence the accuracy of affordance perception. The first is based on their potential effect on organism's energy level. The second is related to the disruption of participants' attunement to optical variables relevant for action guidance and/or to perceptual-motor calibration.

Abstract
Alongside concern about the physical health impacts of the coronavirus disease 2019 (COVID-19) crisis, public health officials have also raised concerns about the potential for massive mental health impact. This has led many to wonder, how are individuals with obsessive-compulsive disorder (OCD), and especially those with contamination fears, doing in the era of COVID-19? We present data from eight patients in our residential treatment program for OCD who were admitted prior to any COVID-19 restrictions and continued in treatment at the facility during the pandemic. Much like the general population, our patients varied in the ways they were impacted by COVID-19, yet the majority experienced improvements in OCD symptoms despite the context. This is not to downplay the many ways in which our patients were personally affected by COVID-19. Rather our patients’ relatively resilient responses mirror our program’s treatment model, which emphasizes exposure and response prevention (ERP) within the complementary framework of acceptance and commitment therapy (ACT). The intention of this article is to challenge the notion that by definition this population will fare worse than the general public or that ERP cannot proceed effectively during this time. In contrast, we underscore that effective OCD treatment can and should continue in the era of COVID-19.
