BACKGROUND Confusion between similar drug names is a common cause of potentially harmful medication errors. Interventions to prevent these errors at the point of prescribing have had limited success. The purpose of this study is to measure whether indication alerts at the time of computerized physician order entry (CPOE) can intercept drug name confusion errors. METHODS AND FINDINGS A retrosp...

Consider the class of experimental situations where there are n possible stimulus presentations and n possible responses and there is an expelimenter-defined one-one stimulus-response mapping. Then a confusion matrix is a table with the following properties: The stimuli are given row identification such that the cell entries are conditional frequencies that the column response is made to the ro...

Fine-Grained Visual Classification (FGVC) datasets contain small sample sizes, along with significant intra-class variation and interclass similarity. While prior work has addressed intra-class variation using localization and segmentation techniques, inter-class similarity may also affect feature learning and reduce classification performance. In this work, we address this problem using a nove...

Spoken word recognition involves selecting one word out of many competing candidate word-forms. However, there i s disagreement as to what candidates actually compete with each other given a particular signal, though similarity i s commonly invoked. We investigate whether the word similarity literature, drawing from explicit similarity judgments of word forms, can speak to this current state of...

Participants wore a smartphone, which collected GPS, audio, accelerometry and image data, in a pouch around their necks for a period of two weeks. After a retention interval of one week, they were asked to judge the specific day on which each of a selection of images was taken. To account for people’s judgements, we proposed a mixture model of four processes uniform guessing, a signal detection...

KOSSLYN, STEPHEN M., and BOWER, GORDON H. The Role of Imagery in Sentence Memory: A Developmental Study. CHILD DEVELOPMENT, 1974, 45, 30-38. This experiment tested whether children rely relatively more than adults on sensory imagery as the internal representation of sentences in memory. If so, then children should show more confusions in recognition memory between sentences which evoke very sim...

This work is an attempt to construct a perceptual representation of Thai consonants based on perceptual identification results (from 28 Thais) of 21 phonemes presented in noise. The experiment is designed to equally make pairwise comparisons among 21 word-initial phonemes, which results in 210 real-word stimulus pairs. Percent correct responses and confusion matrices are obtained. Similarity sc...
