From: Even affective changes induced by the global health crisis are insufficient to perturb the hyper-stability of visual long-term memory

Visual recognition memory was highly stable despite large changes in pandemic state and perceived emotional states. A Adult participants (200 in each data collection, 1000 total) were asked to remember 100 pictures, with 5 exemplars from 20 semantic categories. Each picture was shown for 250 ms during the encoding phase. They were later tested by recognizing the studied pictures from a stream of 200 pictures, consisting of all 100 studied pictures and 100 new pictures with the same number of exemplars from the same semantic categories. B COVID-19 case numbers influence on subject’s self-reported positive and negative affect. C Recognition memory performance (proportion correct) did not change with respect to the time of data collection, even as COVID-19 cases in the US varied drastically. The mean, variance, and skewness of the d-prime index of memory sensitivity were also statistically unchanged across the five data collections (see Additional file 1: Fig. S1). D Pairwise correlations between February recognition accuracy of each item and recognition from each other data collection period
