Parsing a cognitive task : a characterization of the mind’s bottleneck
Parsing a mental operation into components, characterizing the parallel or serial nature of this flow, and understanding what each process ultimately contributes to response time are fundamental questions in cognitive ...
Dynamics of the central bottleneck : dual-task and task uncertainty
Why is the human brain fundamentally limited when attempting to execute two tasks at the same time or in close succession? Two classical paradigms, psychological refractory period (PRP) and task switching, have independently ...
The Spatial and Temporal Construction of Confidence in the Visual Scene
Human subjects can report many items of a cluttered field a few hundred milliseconds after stimulus presentation. This memory decays rapidly and after a second only 3 or 4 items can be stored in working memory. Here we ...
Delays without mistakes : response time and error distributions in dual-task
Background: When two tasks are presented within a short interval, a delay in the execution of the second task has been systematically observed. Psychological theorizing has argued that while sensory and motor operations ...
Bridging psychology and mathematics : can the brain understand the brain?
We are told scientists are divided into experimentalists and theoreticians. The dialectic description of the dynamics of science, with one tribe gathering data and collecting evidence and another tribe providing form to ...
