Sequences of choice response times exhibit ubiquitous and strong multiscale dynamics (i.e., sequential dependencies across a broad range of temporal scales). Despite their pervasive nature, multiscale dynamics are poorly understood. We show that dynamics in the seconds to minutes range can be explained by the superposition of several distinct learning and control mechanisms. Each mechanism learns a representation of the structure of the choice environment and/or an aspect of the decision-maker's ability. These representations are updated after each choice and used to control the next decision by modulating the parameters of an evidence accumulation process with subsecond range dynamics that determine individual choices. We link these mechanisms to three major foci in the experimental study of sequential dependencies: stimulus history, error-related, and hard-easy effects. This account provides a detailed explanation of both multiscale dynamics of choice sequences, and the three effects, at the group and individual levels.

Previous research suggests that the MINERVA2 model can capture basic Deese/Roediger/McDermott (DRM) false recognition findings with either randomized representations or distributional semantic representations. In the current article, we extended this line of research by showing that MINERVA2 can accommodate not only basic DRM recognition findings but also the effects of various theory-driven manipulations. Importantly, we incorporated two assumptions of fuzzy-trace theory into MINERVA2: the verbatim-gist distinction and hierarchies of gist. To implement the verbatim-gist distinction, we represented local gist traces with distributional semantic vectors and verbatim traces with holographic word-form vectors. With separate representations incorporated, MINERVA2 successfully simulated a wide range of empirical effects in the DRM illusion, as well as remember/know and source judgments. To incorporate hierarchies of gist into the framework, we added an assumption that an item's storage quality depends on its semantic similarity to the preceding item. This accommodated the effect of global gist beyond that of local gist and solved the problem of storage independence in multitrace models of episodic memory. Our findings provided extensive evidence that MINERVA2 is a viable candidate for scalable modeling of the DRM illusion and strengthened the connection between computational modeling and substantive theories of false memory.

Our premodern ancestors had perceptual, motoric, and cognitive functional domains that were modularly encapsulated. Some of these came to interact through a new type of cross-modular binding in our species. This allowed previously domain-dedicated, encapsulated motoric and sensory operators to operate on operands for which they had not evolved. Such operators could at times operate nonvolitionally, while at other times they could be governed volitionally. In particular, motoric operations that derive from the same circuits that compute hand motions for object manipulation could now be retooled for virtual manipulation in a mental workspace in the absence of any physical hand or other effector movements. I hypothesize that the creativity of human imagination and mental models is rooted in premotor simulation of sequential manipulations of objects and symbols in the mental workspace, in analogy with the premotor theory of attention, which argues that attention evolved from "internalized" eye movement circuitry. Overall, operator "disencapsulation" led to a bifurcation of consciousness in humans: a concrete form centered on perception of the body in the physical world and an abstract form focused on explanatory mental models. One of the consequences of these new abilities was the advent of psychotic disorders that do not exist in species possessed solely of the concrete type of consciousness.
