Speed versus accuracy in cognitive assessment when using CSIs

Csis 0351 / Csis 8601 :

Consider the black box sampling problem that is described as follows. Suppose a black box contains red balls and blue balls. The number of red balls, which can be zero, is unknown. One is allowed to sample (with replacement) uniformly at random from the bag. Call an access to the black box positive if one samples a red ball and negative otherwise. The goal is to estimate the probability that an...

When natural selection should optimize speed-accuracy trade-offs

Planning versus speed: an experimental examination of what Planned Codes of the Cognitive Assessment System measures.

This study provided validity evidence that the Cognitive Assessment System, Planned Codes subtest measures planning rather than speed. Each of 156 children completed Planned Codes using two different sets of directions. The first set of directions allowed each child to use strategies to complete Planned Codes. The second set of directions allowed the child only to use speed to complete Planned ...

High-speed high-accuracy three- dimensional shape measurement using digital binary defocusing method versus sinusoidal method

This paper presents our research findings on high-speed high-accuracy three-dimensional shape measurement using digital light processing (DLP) technologies. In particular, we compare two different sinusoidal fringe generation techniques using the DLP projection devices: direct projection of computer-generated 8-bit sinusoidal patterns (a.k.a., the sinusoidal method), and the creation of sinusoi...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
