Sensitivity to hypothesis size during information search.

Optimum Wordlength Search Using Sensitivity Information

Many digital signal processing algorithms are first developed in floating point and later converted into fixed point for digital hardware implementation. During this conversion, more than 50% of the design time may be spent for complex designs, and optimum wordlengths are searched by trading off hardware complexity for arithmetic precision at system outputs. We propose a fast algorithm for sear...

Adaptive information source selection during hypothesis testing

We consider how the information sources people use to test hypotheses change as the sparsity of the hypotheses – the proportion of items in the hypothesis space they include – changes. Specifically, we focus on understanding how requests for positive and negative evidence, which have been shown to be sensitive to hypothesis sparsity (Hendrickson, Navarro, & Perfors, in prep), are influenced by ...

Identifying Ferdowsi University of Mashhad Graduated Students' Search Strategies during their Information-searching through the Web

Purpose: the aim was to identify users' search strategies and the rate of using search strategies on the web. Method: It is a practical survey. The statistical population included all the postgraduate students in the first semester at Ferdowsi University of Mashhad. 95 students were selected by stratified random sampling method. To gather the data, log files were used. Findings: 12 search strat...

Recall and recognition memory during posthypnotic amnesia: a failure to confirm the disrupted-search hypothesis and the memory disorganization hypothesis.

Recent research has led some investigators to hypothesize that posthypnotic amnesia is characterized by a disruption in the memory search process and, more generally, by disorganization in memory retrieval. Data to test these hypotheses were provided by 141 male and female undergraduates administered the Stanford Hypnotic Susceptibility Scales, Forms B and C. Amnesia was assessed by the usual r...
