ABSTRACT
The discrete events assumed to occur in problem solving behavior (where an unpracticed person is trying to identify the rule being used in the binary classification of objects) have been modeled using SNOBOL4. The main assumption of this cognitive simulation is that attention given to unexpected characteristics of succeeding objects drive the behavior of the S (subject). Specifically, the simulated Ss with smaller short-term memories indicated a strong recency effect: rules represented by values occurring in the last positions in the instance were significantly easier to identify. For the largest memory size used, a significant primacy effect was seen.

Anterior intraparietal sulcus is sensitive to bottom-up attention driven by stimulus salience
Frontal eye fields (FEF) and anterior intraparietal sulcus (aIPS) are involved in the control of voluntary attention in humans, but their functional differences remain poorly understood. We examined the activity in these brain regions as a function of ...
Interactions between voluntary and stimulus-driven spatial attention mechanisms across sensory modalities
In everyday life, the allocation of spatial attention typically entails the interplay between voluntary (endogenous) and stimulus-driven (exogenous) attention. Furthermore, stimuli in different sensory modalities can jointly influence the direction of ...
Electrophysiological correlates of stimulus-driven reorienting deficits after interference with right parietal cortex during a spatial attention task: A tms-eeg study
TMS interference over right intraparietal sulcus (IPS) causally disrupts behaviorally and EEG rhythmic correlates of endogenous spatial orienting before visual target presentation [Capotosto, P., Babiloni, C., Romani, G. L., & Corbetta, M. Differential ...
