Causally defective remembering: a study on the folk concept of memory

The standard argument for the causal theory of memory relies on intuitions about scenarios in which subjects accurately represent events from their pasts but do so in a “causally defective” manner. Examples include representations based on suggestion and representations based on relearned information. According to causalists, these scenarios, intuitively, are not cases of remembering. This paper applies the methods of experimental philosophy to determine whether laypeople share causalist intuitions. We find that, in scenarios in which all of the causal theory’s requirements for remembering are fulfilled and in scenarios in which none of these requirements are fulfilled, laypeople’s intuitions align with the causal theory’s verdicts: they clearly ascribe remembering in the former scenarios and clearly deny remembering in the latter scenarios. In causally defective scenarios – scenarios in which some but not all of the requirements of the causal theory are fulfilled – a more complex pattern of responses is observed, with some participants ascribing remembering even in cases that do not satisfy causalist requirements. In particular, while many participants deny that remembering occurs in relearning, many do the opposite. These results suggest that folk ascriptions of remembering only partly align with the causal theory of memory.
