Translating working memory into action: Behavioral and neural evidence for using motor representations in encoding visuo-spatial sequences

Visuo-spatial Working Memory

Neural circuit basis of visuo-spatial working memory precision: a computational and behavioral study.

The amount of information that can be retained in working memory (WM) is limited. Limitations of WM capacity have been the subject of intense research, especially in trying to specify algorithmic models for WM. Comparatively, neural circuit perspectives have barely been used to test WM limitations in behavioral experiments. Here we used a neuronal microcircuit model for visuo-spatial WM (vsWM) ...

Adult ADHD and working memory: neural evidence of impaired encoding.

OBJECTIVES To investigate neural and behavioural correlates of visual encoding during a working memory (WM) task in young adults with and without Attention-Deficit/Hyperactivity Disorder (ADHD). METHODS A sample of 30 college students currently meeting a diagnosis of ADHD and 25 typically developing students, matched on age and gender, performed a delayed match-to-sample task with low and hig...

Encoding specific associative memory: evidence from behavioral and neural manipulations.

Within-subjects procedures with rats assessed the associative structures acquired during conditioning trials in which the interval between the stimuli and food was either short or long (i.e., A-10 s→food and B-40 s→food). In Experiments 1 and 2, after these conditioning trials, A and B served as second-order reinforcers for 2 further stimuli (i.e., X→A and Y→B); whereas Experiment 3 used a sens...

Working Memory Concept Encoding Using Holographic Reduced Representations

Artificial neural networks (ANNs) utilize the biological principles of neural computation to solve engineering problems, and ANNs also serve as formal, testable hypotheses of brain function and learning in the cognitive sciences. However, ANNs are often underutilized in applications where symbolic encoding (SE) of conceptual information is preferred (robotics, games, theorem proving, etc.) sinc...
