The patients with FLE took longer to complete the four levels of difficulty of the short-term memory game than healthy controls (level 1: U\u2009=\u20092974.50, <jats:italic>p<\/jats:italic>\u2009=\u20090.000; level 2: U\u2009=\u20093060.50, <jats:italic>p<\/jats:italic>\u2009=\u20090.000; level 3: U\u2009=\u20092465.00, <jats:italic>p<\/jats:italic>\u2009=\u20090.000; level 4: U\u2009=\u20092199.00, <jats:italic>p<\/jats:italic>\u2009=\u20090.000). During the memory decoding period, first fixation on the targets took significantly longer for FLE patients for all difficulty levels compared to controls (level 1: U\u2009=\u20093407.00, <jats:italic>p<\/jats:italic>\u2009=\u20090.008; level 2: U\u2009=\u20093618.00, <jats:italic>p<\/jats:italic>\u2009=\u20090.036; level 3: U\u2009=\u20093345.00, <jats:italic>p<\/jats:italic>\u2009=\u20090.006; level 4: U\u2009=\u20092781.00, <jats:italic>p<\/jats:italic>\u2009=\u20090.000). The average fixation duration per target among patients with FLE was found to be significantly longer compared to HC (level 1: U\u2009=\u20092994.50, <jats:italic>p<\/jats:italic>\u2009=\u20090.000; level 2: U\u2009=\u20093101.00, <jats:italic>p<\/jats:italic>\u2009=\u20090.000; level 3: U\u2009=\u20092559.50, p\u2009=\u20090.000; level 4: U\u2009=\u20092184.50, <jats:italic>p<\/jats:italic>\u2009=\u20090.000). The total fixation duration on AOI\/total completion time of FLE patients was significantly lower than those of HC for levels 1 to 3 (level 1: U\u2009=\u20091557.00, <jats:italic>p<\/jats:italic>\u2009=\u20090.000; level 2: U\u2009=\u20092333.00, <jats:italic>p<\/jats:italic>\u2009=\u20090.000; level 3: U\u2009=\u20092757.00, <jats:italic>p<\/jats:italic>\u2009=\u20090.000).
