Cue competition and feature representation in a category learning task: an fMRI study
… in this context. The present experiment used representational similarity analyses (RSA), a method for interrogating representational structure (Kriegeskorte et al., 2008), in order to examine where and how features were represented during overshadowing in a category learning task. Participants …

The Structural Representation of Three -Way Proximity Data
… of proximity matrices. Most commonly, the representational structure is fit to the observed data through minimizing the least-squares loss function; traditional implementations rely typically on gradient or sub-gradient optimization. Alternatively, scaling and clustering can be reformulated …

Grounded Situation Models for Situated Conversational Assistants
… idea is to endow agents with a sensor-updated "structured blackboard" representational structure called a Grounded Situation Model (GSM), which is closely related to the cognitive psychology notion of situation models. The GSM serves as a workspace with contents similar to a "theatrical stage" …

Electrophysiological systems underlying human domain-general cognition and selective attention
… multiple-demand (MD) network. Using representational similarity analysis (RSA)-based MEG-fMRI fusion, I demonstrate that aperiodic broadband power most strongly shares task demand-related representational structure with MD activation, establishing a link between this …

Unbiasing Information Search and Processing through Personal and Social Identity Mechanisms
… contextually activated, inducing a more complex representational structure of the self may broaden the set of contacts from whom individuals seek information. The bias-mitigative potential of self-affirmation and social identity complexity is examined here in a series of dispute contexts — two …

Kant on the Progression of Representation
… on a conflation of two importantly distinct representational states, namely 'intuition' [Anschaaung] and 'perception' [Wahrnehmung]. I argue that once this distinction is noted, many of the passages that would appear to threaten a nonconceptualist interpretation lose their force. In addition, …

Modeling Cognition by Pruning and Topography-Learning in Deep Neural Networks
… high performance alone does not imply human-like representational structure. This motivates developing algorithms that not only improve benchmarks but also produce representations that are better aligned with human brain or behavior, so that models can be considered as mechanistic accounts for …

Action and rehabilitation in hemispatial neglect
… is better explained by damage to a high-level representational structure that receives input from the ventral visual stream, but not from the dorsal-stream. Consequently, they postulate that neglect patients should code spatial parameters for action veridically. Another strong claim of the …
