آموزش حافظه کاری تطبیقی اثر قابل اغماض محرک های عاطفی بیش از پردازش شناختی را آشکار می سازد

Here we analyze how performance differences in an adaptive cognitive training regime based on the n-back task interact with emotional stimuli (scenes and faces) varying in their valence (negative, positive, and neutral). One hundred and three participants completed four training sessions across 2 weeks showing remarkable improvements from time to time. Results revealed similar results for faces and scenes regarding accuracy levels across increased complexity levels. However, reaction times (RTs) were sensitive to emotional conditions to some extent. Observed faster RTs to negative faces (disgust) were consistent with the negativity bias phenomenon, but this effect vanished for the highest levels of processing complexity. It is suggested that emotional information contents fail to interact with cognition when there are no cognitive resources left after the primary task is addressed.
