Everyday function is influenced by both executive functions and emotions, both individually and in combination with each other. According to research, executive function and the emotional valence of autobiographical memories are related. Particularly, it is believed that positive memories improve executive function whereas negative memories may harm it (Eichenbaum et al., 2007; Pillemer & White, 1989). For instance, participants who could complete tasks requiring planning and decision-making and who could recall more positive autobiographical memories displayed stronger executive function, according to research by Eichenbaum and colleagues (2007). In a similar manner, Pillemer and White (1989) found that those with a history of depression struggled more with executive function-related activities and seemed to recollect more negative autobiographical memories. By facilitating the encoding, storage, and retrieval of information, executive function is essential for memory. It enables people to initiate and maintain attention, prevent distractions, organize and plan information, and keep track of their progress—all of which are necessary for efficient learning and memory consolidation (Diamond, 2013; Miyake & Friedman, 2012). Executive function, which consists of attention, working memory, and inhibitory control, is influenced by affective characteristics such as perceived stress, perceived hostility, and positive affect (Diamond, 2013; Stuss & Knight, 2013). Whereas perceived stress and hostility might impede memory and cognitive control (Kuhlmann, Piel, & Wolf,, 2018; Shields et al., 2017), positive affect has been shown to improve cognitive function (Fredrickson, 2004; Schmeichel, 2007). Declines in cognitive capacities, especially executive function, are linked to aging (Harada, Natelson Love, & Triebel, 2013). Aging has been linked to decreased inhibitory control, working memory, and attentional control, according to prior studies (Bopp & Verhaeghen, 2005; Hedden & Gabrieli, 2004). Executive function may affect how much people pay attention to and interpret information in a positive or negative manner, resulting in the formation of positive or negative memories (Mather & Knight, 2005). Old adults typically recall more pleasant memories as they age, which may be related to aging-related changes in motivation and goals (Carstensen & DeLiema, 2018). Young adults tend to remember more negative experiences than older adults do, whereas older adults may remember more positive experiences (Carstensen & DeLiema, 2018). This aging-related change in memory valence may be connected to age-related motivational changes that influence behavior and cognitive processing as opposed to neural or cognitive impairment (Carstensen & DeLiema, 2018; Mather & Knight, 2005). It is crucial to take into account how executive function and affective qualities interact in both younger and older adults in order to comprehend the impact of emotion on memory recollection during the course of a person's life. As it enables people to better control their emotions and concentrate on positive information, executive function has been suggested to have a role in the positivity bias observed in older adults (Mather & Knight, 2005). As a result, investigating the connection between executive function and affective characteristics like emotion regulation can shed light on the mechanisms driving age-related changes in memory valence (Carstensen & DeLiema, 2018). There has been little research done on the interplay between affective qualities and executive functions in how they impact the valence of autobiographical recollections. The proposed study aims to examine whether individual affective dimensions (perceived stress, perceived hostility, and positive affect) moderate the relationship between executive function (including attention, working memory, and inhibitory control) and one’s tendency to recall personal memories with more positive or negative tone. In this study, the sample will be derived from an open access dataset using a cross-sectional approach. As part of this dataset, tests of executive function, assessments of perceived stress, perceived hostility, and positive affect, as well as an interview about autobiographical recollections, were administered to a sample of healthy younger and older adults. This research will advance our understanding of the intricate relationships between emotion and cognition and shed light on the interplay between cognition and emotion manifest in everyday recollection and how this changes with age.
