Attentional allocation locally warps representational space

Forms of momentum across space: representational, operational, and attentional.

Cognition can exhibit biases consistent with future expectations, and some of these biases result in momentum-like effects and have been linked with the idea of an internalization of the effects of momentum. These momentum-like effects include representational momentum, operational momentum, and attentional momentum. Similarities and differences between these different momentum-like effects are...

Development of Attentional Allocation

Top-down control over attention was investigated on a dual task in 10-year-olds (N = 15) and adults (N = 21). The tasks were an auditory Digit Span and a simple visual Response Time task. In four conditions, participants performed neither (no-task), one (Digit Span or Response Time only), or both tasks (dual). Dependent variables were Digit Span accuracy, response time, and pupillary dilation t...

Adaptive allocation of attentional gain.

Humans are adept at distinguishing between stimuli that are very similar, an ability that is particularly crucial when the outcome is of serious consequence (e.g., for a surgeon or air-traffic controller). Traditionally, selective attention was thought to facilitate perception by increasing the gain of sensory neurons tuned to the defining features of a behaviorally relevant object (e.g., color...

Attentional and Representational Flexibility of Feature Inference Learning

Previous research has revealed differences in what is learned when people acquire concepts through inference and supervised classification. Following these findings, we hypothesized that another difference is representational flexibility in novel category contrasts. An experiment tested the flexibility of category representations across inference and classification tasks by (1) having people ma...
