How Should Observers Allocate Limited Transsaccadic Memory in a Visual Search Task?

Transsaccadic memory for visual object detail.

When we move our eyes around in real-world scenes, we typically have several peripheral previews of an object before we direct our eyes straight at the object. Numerous studies on transsaccadic memory have investigated whether there is any evidence for the integration of peripheral object information acquired presaccadically with foveal object information acquired postsaccadically. We review th...

Placing a Lower Bound on Transsaccadic Memory Capacity Using Visual Search.

Making eye-movements provides us with visual samples of the world that must be integrated to produce a coherent percept of the visual world. Transsaccadic Memory (TSM) is necessary for storing samples from previous fixations so they can be integrated with the current one. Visual search tasks place greater demands on TSM than change-detection since visual search often requires integration of mul...

Visual Search Versus Memory in a Paired Associate Task

The Digit Symbol Substitution Test (DSST) has been used to study various effects, like aging and fatigue. Multiple cognitive and perceptual processes, like associative memory and visual search, are prominently utilized in the DSST. Understanding how these processes contribute to execution of tasks like the DSST is important to human factors research, as moderators like age and fatigue may diffe...

How to Use Limited Memory in Heuristic Search

Traditional best-first search for optimal solutions quickly runs out of space even for problem instances of moderate size, and linearspace search has unnecessarily long running times since it cannot make use of available memory. For using available memory effectively, we developed a new generic approach to heuristie search. It integrates various strategies and includes ideas from bidirectional ...
