Task Manipulation Effects On The Relationship Between Working Memory Capacity And Go/No-Go Performance, Elizabeth A. Wiemers
Task Manipulation Effects On The Relationship Between Working Memory Capacity And Go/No-Go Performance, Elizabeth A. Wiemers
Open Access Theses
Seemingly minor task manipulations can have large and sometimes unpredicted effects on task performance. Despite this, single tasks are typical in both research and assessment applications. This series of experiments aims to systematically investigate the differences between various perceptual and semantic versions of go/no-go tasks and their relationships with working memory capacity (WMC) with the goal of determining the cause of inconsistencies in the literature. Because these versions of the go/no-go have not previously been systematically studied, the first experiment does so. After determining which performance differences exist based on versions of both task and decision, and noting that these …

Focusing On Selection For Fixation, John K. Tsotsos, Calden Wloka, Yulia Kotseruba
MODVIS Workshop
Building on our presentation at MODVIS 2015, we continue in our quest to discover a functional, computational, explanation of the relationship among visual attention, interpretation of visual stimuli, and eye movements, and how these produce visual behavior. Here, we focus on one component, how selection is accomplished for the next fixation. The popularity of saliency map models drives the inference that this is solved; we suggested otherwise at MODVIS 2015. Here, we provide additional empirical and theoretical arguments. We then develop arguments that a cluster of complementary, conspicuity representations drive selection, modulated by task goals and history, leading to a …
