For example, during retrieval, pupils dilate more to previously-seen old items compared to new items, a phenomenon called the pupil old/new effect. Encoding variables that influence the strength of the memory trace for encoded stimuli play a role in successful discrimination of new versus old items. Additionally, the cognitive load during encoding (i.e., the effort needed to encode information), also impacts memory success by taking up mental resources needed to successfully encode information. In this study, I conducted a meta-analysis to examine whether pupillary dilation effects are stronger after encoding manipulations that influence memory strength or cognitive load. This analysis showed that both memory strength and cognitive load affect pupil dilations. However, the impact was greater for cognitive load, suggesting that the amount of effort...
