Abstract

Counterfactual imaginings are known to have far-reaching implications. In the present experiment, we ask if imagining events from one's past can affect memory for childhood events. We draw on the social psychology literature showing that imagining a future event increases the subjective likelihood that the event will occur. The concepts of cognitive availability and the source-monitoring framework provide reasons to expect that imagination may inflate confidence that a childhood event occurred. However, people routinely produce myriad counterfactual imaginings (i.e., daydreams and fantasies) but usually do not confuse them with past experiences. To determine the effects of imagining a childhood event, we pretested subjects on how confident they were that a number of childhood events had happened, asked them to imagine some of those events, and then gathered new confidence measures. For each of the target items, imagination inflated confidence that the event had occurred in childhood. We discuss implications for situations in which imagination is used as an aid in searching for presumably lost memories.

  • Social pressure, personal expectancy, misleading information, leading questions, and imagery inflation can all contribute to false memory formation.

    “Social pressure, personal expectancy, misleading information, leading questions, and imagery inflation can all contribute to false memory formation (Garry et al., 1996; Hirt et al., 1999; Loftus, 1975; Reysen, 2007).”

    The Results report increased confidence after imagining a childhood event, and the Discussion says imagination may strengthen belief that an event occurred. The authors caution that increased confidence does not establish a fully developed false memory. The paper does not substantiate the other listed factors—social pressure, personal expectancy, misleading information, and leading questions—as causes of false memory formation. (LLM, conf=0.88)

  • Failures of source or reality monitoring occur because remembered and imagined events are often very similar in content and phenomenology, for instance when imagined events are elaborate, vivid, and plausible.

    “By the continuist view, failures of source/reality monitoring occur because remembered and imagined events are often very similar in content and phenomenology, for instance, when imagined events are elaborate, vivid, and plausible (Devitt, Monk-Fromont, Schacter, & Addis, 2016;Garry, Manning, Loftus, & Sherman, 1996;Johnson et al., 1993).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
