Quantifying Errors Of Bias And Discriminability Emitted By Children During A Matching-To-Sample Task, Courtney Hannula
Theses and Dissertations
Children diagnosed with Autism Spectrum Disorders (ASD) make errors during discrimination training regardless of antecedent or consequent procedures implemented to decrease errors. Further, these interventions are not guided by the source of errors. Two equations from Davison and Tustin’s (1978) framework can quantify errors due to bias and discriminability, known as log𝑏 and log𝑑, respectively. This framework categorized errors emitted by children diagnosed with ASD during a matching-to-sample task. The task was displayed on a touchscreen device in which touching a sample stimulus at the beginning of each trial resulted in the appearance of two comparison stimuli. Researchers delivered reinforcement …

The Effects Anxiety Has On Attentional Bias And Working Memory, Breana Mcswain

Research has shown that anxiety impairs attention and working memory, especially when it comes to completing a mentally demanding cognitive task such as the emotional Stroop paradigm or the n-back task.

State anxiety was induced using negatively valenced images from the International Affective Picture System, while neutral images served as the control. We compared behavioral performance between individuals in the negative mood induction against those in the neutral mood induction. Trait anxiety was used as a covariate for both groups. This allowed …
