Spatial frequency manipulations have been shown to have significant utility in ascertaining the various types of information that might be important in object identification and recognition tasks. This utility suggests that, given some mapping between ranges of spatial frequencies and different types of psychological information, it should be possible to examine the roles of these different typ...

Informational masking of a target female talker by female distracters was measured with target and distracters presented from directly in front of the listener as a baseline condition. Next, it was found that if the distracters were also presented from directly in back of the listener, advanced or delayed by a few milliseconds with respect to the distracters in front, release from informational...

Two general views on the role of memory in cognitive skills--an instance-based theory and an associative perspective--were compared with respect to their general assumptions about the information involved and the processes that operate on that information. Characteristics of memory information were examined in terms of predictions for transfer to various stimulus forms as a function of 2 types ...

A linear pursuit problem in the plane under incomplete pursuer information about the evader is investigated. At discrete time instants, the pursuer measures with errors the angle of vision to the evader, the angular velocity of the line of sight, and the relative distance. Other combinations of measurable parameters are possible (for example, angle of vision and relative distance or angle of vi...

This paper examines the interplay of informational and payoff externalities in a two-player strategic investment game. Each players learns about the quality of a new technology by observing a private signal and the action of his opponent, and has the option of irreversibly adopting it. I characterize the set of equilibrium payoffs in the timing game in which there is second-mover advantage and ...

This paper examines a nearly untested premise of the resource-based view of the Žrm: managers can exploit uncertainty about a factor’s true value to generate returns. Our results show that empirically validating this basic proposition is difŽcult and potentially impossible, despite our use of a rather simple empirical setting. While market imperfections appear to underlie the payment of basebal...

Telescopes reveal that elements are formed through the recombination of subatomic particles within supernovae, producing the nebulae in which galaxies coalesce. Microscopes reveal that eukaryotic organisms form through the recombination of prokaryotic cells, producing plants and animals that recombine to propagate as communities. Microscopists and astronomers alike have thus begun to wonder whe...

Introduction: The diagnosis of cancer involves the patients, their caregivers, and families. Caregivers should obtain guidance from health care professionals to promote care facilities. The current study aimed at investigating the economic, socio-individual, informational, and psycho-spiritual problems of caregivers in post-treatment phase of breast cancer. Methods: The present descriptive stu...

A masker can reduce target intelligibility both by interfering with the target's peripheral representation ("energetic masking") and/or by causing more central interference ("informational masking"). Intelligibility generally improves with increasing spatial separation between two sources, an effect known as spatial release from masking (SRM). Here, SRM was measured using two concurrent sine-vo...
