It is well established that prior knowledge influences reconstruction from memory, but the specific interactions of memory and knowledge are unclear. Extending work by Huttenlocher et al. (Psychological Review, 98 [1991] 352; Journal of Experimental Psychology: General, 129 [2000] 220), we propose a Bayesian model of reconstructive memory in which prior knowledge interacts with episodic memory at multiple levels of abstraction. The combination of prior knowledge and noisy memory representations is dependent on familiarity. We present empirical evidence of the influences (...) of prior knowledge at multiple levels of abstraction, showing that the reconstruction of familiar objects is influenced toward the specific prior for that object, while unfamiliar objects are influenced toward the overall category.

We evaluate the literature on the memorability of supernatural concepts, itself part of a growing body of work in the emerging cognitive science of religion. Specifically, we focus on Boyer’s Minimally Counterintuitive hypothesis according to which supernatural concepts tap a cognitively privileged memory-enhancing mechanism linked to violations of default intuitive inferences. Our assessment reveals that the literature on the MCI hypothesis is mired in empirical contradictions and methodological shortcomings which makes it difficult to assess the validity of competing theoretical models, (...) including the MCI hypothesis itself. In light of this fractured picture, we make the case for an account of the MCI effect which dispenses with a memory mechanism specific to supernatural concepts. This account has several desirable properties. First, it preserves Boyer’s pioneering insights regarding the ontological status of supernatural concepts and the cognitive mechanisms that give rise to their cultural prevalence. Second, our account is based on independently-motivated mechanisms that are well-established in the literature. Third, this account offers a principled resolution of the tension in the extant literature between studies that do replicate the MCI effect and those that seemingly fail to do so. Finally, because the proposed mechanisms are not specific to supernatural concepts, the scope of the MCI effect may be extended to account for a broader range of highly transmissible concepts than those it was originally intended to explain. We conclude with a set of theoretical and methodological prescriptions designed to guide future research on the memorability of supernatural concepts. (shrink)

The minimally counterintuitive (MCI) thesis in the cognitive science of religion proposes that supernatural concepts are prevalent across cultures because they possess a common structure—namely, violations of intuitive ontological assumptions that facilitate concept representation. These violations are hypothesized to give supernatural concepts a memorability advantage over both intuitive concepts and “maximally counterintuitive” (MXCI) concepts, which contain numerous ontological violations. However, the connection between MCI concepts and bizarre (BIZ) but not supernatural concepts, for which memorability advantages are predicted by the von (...) Restorff (VR) effect, has been insufficiently clarified by earlier research. Additionally, the role of inferential potential (IP) in determining MCI concepts’ memorability has remained vague and only rarely controlled for. In a pre‐registered experiment, we directly compare memorability for MCI and MXCI concepts, compared to BIZ concepts, while controlling for IP as well as degree of bizarreness. Results indicate that when IP and bizarreness are controlled for, memorability of counterintuitive and BIZ concepts—relative to intuitive control concepts—is similar across concepts with one, two, and three characteristics. Findings suggest that the MCI and VR effects may be manifestations of the same underlying mechanisms. (shrink)

Recent evidence suggests that experienced events are often mapped to too many episodic states, including those that are logically or experimentally incompatible with one another. For example, episodic over-distribution patterns show that the probability of accepting an item under different mutually exclusive conditions violates the disjunction rule. A related example, called subadditivity, occurs when the probability of accepting an item under mutually exclusive and exhaustive instruction conditions sums to a number >1. Both the over-distribution effect and subadditivity have been widely (...) observed in item and source-memory paradigms. These phenomena are difficult to explain using standard memory frameworks, such as signal-detection theory. A dual-trace model called the over-distribution model can explain the episodic over-distribution effect, but not subadditivity. Our goal is to develop a model that can explain both effects. In this paper, we propose the Generalized Quantum Episodic Memory model, which extends the Quantum Episodic Memory model developed by Brainerd, Wang, and Reyna. We test GQEM by comparing it to the OD model using data from a novel item-memory experiment and a previously published source-memory experiment examining the over-distribution effect. Using the best-fit parameters from the over-distribution experiments, we conclude by showing that the GQEM model can also account for subadditivity. Overall these results add to a growing body of evidence suggesting that quantum probability theory is a valuable tool in modeling recognition memory. (shrink)
