Framing the past (and future): Effects of generic photos on autobiographical judgments.

Do the images we see every day influence how we remember our lives? Research on this matter often concerns how entire memories of events can be created or shaped through the use of doctored photographs of personal (Wade et al., Psychonomic bulletin & review, 9 (3), 597-603, 2002) and public events (Sacchi et al., Applied Cognitive Psychology, 21 (8), 1005-1022, 2007). Although this paradigm has yielded insights into false memory production, it may underestimate the extent to which photographs can bias or distort memory in a subtler manner (i.e., without the use of doctored photographs or suggestion). In Experiments 1 (N = 95) and 2 (N = 186) of the present study, we examined whether the mere presence of generic images, typical of stock photography, could influence aspects of our memories. Given the parallel between autobiographical remembering and forecasting (Berntsen & Bohn, Memory & Cognition, 38(3), 265-278, 2010), we also examined (Experiment 3: N=204) how such images would influence future autobiographical judgments. Specifically, three experiments investigated whether photographs would bias autobiographical judgments for either quantitative (e.g., How many movies have you seen in the past year?) or affective (e.g., How enjoyable do you think your next date will be?) aspects of events in everyday life. We found that photographs reliably influenced judgments related to quantitative aspects of autobiographical events. Moreover, though less robustly, there was an indication that these photos could bias our affective construal of such events as well. Overall, we conclude that the mere presence of generic photographs may exert an influence on the way we think about our lives to an extent previously under-recognized.
