The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend Oct 2010

The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend

Psychology Faculty Publications

The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a model of mental processes. Despite its demonstrated utility, the methodology has lacked a method for statistical testing until now. In this paper we briefly describe the SIC then develop some basic statistical properties of the measure. These developments lead to a statistical test for rejecting certain classes of models based on the SIC. We verify these tests using simulated data, then demonstrate their use on data from a simple cognitive task.


Listen Carefully: The Risk Of Error In Spoken Medication Orders, Conor T. Mclennan Jan 2010

Listen Carefully: The Risk Of Error In Spoken Medication Orders, Conor T. Mclennan

Psychology Faculty Publications

Clinicians and patients often confuse drug names that sound alike. We conducted auditory perception experiments in the United States to assess the impact of similarity, familiarity, background noise and other factors on clinicians' (physicians, family pharmacists, nurses) and laypersons' ability to identify spoken drug names. We found that accuracy increased significantly as the signal-to-noise (S/N) ratio increased, as subjective familiarity with the name increased and as the national prescribing frequency of the name increased. For clinicians only, similarity to other drug names reduced identification accuracy, especially when the neighboring names were frequently prescribed. When one name was substituted for another, …


A New Perspective On Visual Word Processing Efficiency, Joseph W. Houpt, James T. Townsend Jan 2010

A New Perspective On Visual Word Processing Efficiency, Joseph W. Houpt, James T. Townsend

Psychology Faculty Publications

As a fundamental part of our daily lives, visual word processing has received much attention in the psychological literature. Despite the well established perceptual advantages of word and pseudoword context using accuracy, a comparable effect using response times has been elusive. Some researchers continue to question whether the advantage due to word context is perceptual. We use the capacity coefficient, a well established, response time based measure of efficiency to provide evidence of word processing as a particularly efficient perceptual process to complement those results from the accuracy domain.


Priming God-Related Concepts Increases Anxiety And Task Persistence, Tina M. Toburen, Brian P. Meier Jan 2010

Priming God-Related Concepts Increases Anxiety And Task Persistence, Tina M. Toburen, Brian P. Meier

Psychology Faculty Publications

Research on the relationship between religiosity and anxiety has been mixed, with some studies revealing a positive relation and other studies revealing a negative relation. The current research used an experimental design, perhaps for the first time, to examine anxiety and task persistence during a stressful situation. Christians and Atheists/Agnostics/Others were primed with God-related or neutral (non-God related) concepts before completing an unsolvable anagram task described as a measure of verbal intelligence. The results revealed that the God-related primes increased both task persistence and anxiousness, which suggests that experimentally induced God-related thoughts caused participants to persist longer on a stressful …


Crossing The ‘Uncanny Valley’: Adaptation To Cartoon Faces Can Influence Perception Of Human Faces, Haiwen Chen, Richard Russell, Ken Nakayama, Margaret Livingstone Jan 2010

Crossing The ‘Uncanny Valley’: Adaptation To Cartoon Faces Can Influence Perception Of Human Faces, Haiwen Chen, Richard Russell, Ken Nakayama, Margaret Livingstone

Psychology Faculty Publications

In this study we assessed whether there is a single face space common to both human and cartoon faces by testing whether adaptation to cartoon faces can affect perception of human faces. Participants were shown Japanese animation cartoon videos containing faces with abnormally large eyes. The use of animated videos eliminated the possibility of position-dependent retinotopic adaptation (because the faces appear at many different locations) and more closely simulated naturalistic exposure. Adaptation to cartoon faces with large eyes significantly shifted preferences for human faces toward larger eyes, consistent with a common, non-retinotopic representation for both cartoon and human faces. This …
