“…Alternatively, similar predictions would stem from recent proposals that people may represent the same events at multiple levels of specificity, forming integrated representations alongside separate ones rather than at their expense (Collin et al, 2015;Schapiro et al, 2017;Brunec et al, 2018;Bowman et al, 2020;Zeithamova and Bowman, 2020). Different representations may be differentially susceptible to the effects of physical similarity, in which case the benefit of increased similarity for generalization (more likely relying on integrated memories) may not be accompanied by a corresponding effect on source memory (more likely relying on separate memories of individual events).…”

The ability to make inferences about related experiences is an important function of memory that allows individuals to build generalizable knowledge. In some cases, however, making inferences may lead to false memories when individuals misremember inferred information as having been observed. One factor that is known to increase the prevalence of false memories is the physical resemblance between new and old information. The extent to which physical resemblance has parallel effects on generalization and memory for the source of inferred associations is not known. To investigate the parallels between memory generalization and false memories, we conducted three experiments using an acquired equivalence paradigm and manipulated physical resemblance between items that made up related experiences. The three experiments showed increased generalization for higher levels of resemblance. Recognition and source memory judgments revealed that high rates of generalization were not always accompanied by high rates of false memories. Thus, physical resemblance across episodes may promote generalization with or without a trade-off in terms of impeding memory specificity.
