There are currently stimuli with published norms available to study several psychological aspects of language and visual cognitions. Norms represent valuable information that can be used as experimental variables or systematically controlled to limit their potential influence on another experimental manipulation. The present work proposes 480 photo stimuli that have been normalized for name, category, familiarity, visual complexity, object agreement, viewpoint agreement, and manipulability. Stimuli are also available in grayscale, blurred, scrambled, and line-drawn version. This set of objects, the Bank Of Standardized Stimuli (BOSS), was created specifically to meet the needs of scientists in cognition, vision and psycholinguistics who work with photo stimuli.

Introduction: Health care providers (HCPs) have experienced more stress and burnout during COVID-19 than before. We compared sources and levels of stress, distress, and approaches to coping between nurses and physicians, and examined whether coping strategies helped mitigate the negative impact of stress and intentions to quit. Methods: Using a cross-sectional study design, burnout was measured with the Maslach Burnout Inventory. Psychological distress was measured using the Depression, Anxiety, and Stress Scale. A self-reported survey was used to evaluate stressors, impact on perceived performance, and intentions to quit. The data were analyzed using t-tests and linear regression models. Results: Responses of 119 HCPs were analyzed. Findings suggest that (1) compared to physicians, nurses experienced a higher level of distress and burnout, and used more maladaptive coping strategies. (2) Both nurses and physicians experienced more distress and burnout during COVID-19 than before. (3) Adaptive coping strategies moderated the negative impact of stress on work performance (4) Adaptive coping strategies moderated the negative effect of stress on burnout, which in turn reduced intentions to quit. Stress negatively impacted work performance and burnout only for those with low, but not high, levels of adaptive coping strategies. Discussion: The current findings of HCPs' challenges, risks, and protective factors provide valuable information (1) on COVID-19's impact on HCPs, (2) to guide the distribution of institutional supportive efforts and recommend adaptive coping strategies, and (3) to inform medical education, such as resilience training, focusing on adaptive coping approaches.

Throughout the last decades, numerous picture data sets have been developed, such as the Snodgrass and Vanderwart (1980) set, and have been normalized for variables such as name and familiarity; however, due to cultural and linguistic differences, norms can vary from one country to another. The effect due specifically to culture has already been demonstrated by comparing samples from different countries where the same language is spoken. On the other hand, it is still not clear how differences between languages may affect norms. The present study explores this issue by collecting and comparing norms on names and many other features from French Canadian speakers and English Canadian speakers living in Montreal, who thus live in similar cultural environments. Norms were collected for the photos of objects from the Bank of Standardized Stimuli (BOSS) by asking participants to name the objects, to categorize them, and to rate their familiarity, visual complexity, object agreement, viewpoint agreement, and manipulability. Names and ratings from the French speakers are available in Appendix A, available in the supplemental materials. The results show that most of the norms are comparable across linguistic groups and also that the ratings given are correlated across linguistic groups. The only significant group differences were found in viewpoint agreement and visual complexity. Overall, there was good concordance between the norms collected from French and English native speakers living in the same cultural setting.
