Retrieval

…He explains why retrieval still matters with long-context models, how chunking and combined retrieval methods affect results, and why reliable citations and feedback from domain experts are central to evaluating a specialized application.

This study explores the fundamental aspects of acquired equivalence learning, where equivalence develops between seemingly unrelated stimuli due to shared consequences. The Rutgers Acquired Equivalence Test (RAET) is a paradigm developed to investigate visually guided equivalence learning, consisting of a learning phase and a test phase. The basal ganglia-frontal cortex pathways play a key role in the learning phase, and the test phase is linked to the functions of the hippocampus-medial temporal lobe.We developed three additional learning tests that differ in the complexity or modality of the

There is an increasing amount of literature that relates the implication of the theta frequency band (4-8 Hz) in spatial memory processes. Moreover, this could be sexually dimorphic, with males and females exhibiting differential patterns during spatial demands, such as landmark encoding, or a differential strategic process, as shown in evoked related potentials (ERPs) studies. However, this has been little explored in complex, allocentric-based spatial memory tasks with frequency band analyses. Thus, this study explored electroencephalographic (EEG) activity in a sample of 40 participants, al

In the Rutgers Acquired Equivalence Test (RAET), participants are taught to associate pairs of visual stimuli (faces and fish) during the acquisition phase. Subsequently, in the test phase, they are required to recall and generalize these learned associations. We introduced a novel test (Polygon) that employs simpler visual stimuli with less semantic content, mirroring RAET's structure. This study was conducted to examine how the complexity and semantic content of visual stimuli impact the performance of migraine sufferers.The psychophysical responses of 41 migraine patients were evaluated acr

Dominant theories of analogical thinking postulate that making an analogy consists in discovering that two superficially different situations share isomorphic systems of similar relations. According to this perspective, the comparison between the two situations may eventually lead to the construction of a schema, which retains the structural aspects they share and deletes their specific contents. We have developed a new approach to analogical thinking, whose purpose is to explain a particular type of analogies: those in which the analogs are exemplars of a schema-governed category (e.g., two i

…models of analogical matching, retrieval, and generalization are used in the Companion cognitive architecture. Examples will include modeling conceptual change, learning by reading, and analogical Q/A training.
