Social Attention During Object Engagement: Toward A Cross-Species Measure Of Preferential Social Orienting, Claire Weichselbaum, Nicole Hendrix, Jordan Albright, Joseph D Dougherty, Kelly N Botteron, John N Constantino, Natasha Marrus

2020-Current year OA Pubs

BACKGROUND: A central challenge in preclinical research investigating the biology of autism spectrum disorder (ASD) is the translation of ASD-related social phenotypes across humans and animal models. Social orienting, an observable, evolutionarily conserved behavior, represents a promising cross-species ASD phenotype given that disrupted social orienting is an early-emerging ASD feature with evidence for predicting familial recurrence. Here, we adapt a competing-stimulus social orienting task from domesticated dogs to naturalistic play behavior in human toddlers and test whether this approach indexes decreased social orienting in ASD.

METHODS: Play behavior was coded from the Autism Diagnostic Observation Schedule (ADOS) in two samples …

Codem: Conditional Domain Embeddings For Scalable Human Activity Recognition, Abu Zaher Md Faridee, Avijoy Chakma, Zahid Hasan, Nirmalya Roy, Archan Misra

Research Collection School Of Computing and Information Systems

We explore the effect of auxiliary labels in improving the classification accuracy of wearable sensor-based human activity recognition (HAR) systems, which are primarily trained with the supervision of the activity labels (e.g. running, walking, jumping). Supplemental meta-data are often available during the data collection process such as body positions of the wearable sensors, subjects' demographic information (e.g. gender, age), and the type of wearable used (e.g. smartphone, smart-watch). This information, while not directly related to the activity classification task, can nonetheless provide auxiliary supervision and has the potential to significantly improve the HAR accuracy by providing extra guidance on how …

Effects Of Positive And Negative Emotion On Picture Naming For People With Mild To Moderate Aphasia: A Preliminary Investigation, Tyson G. Harmon, Courtney Nielsen, Corinne Loveridge, Camille Williams

Faculty Publications

Purpose: To investigate how emotional arousal and valence affect confrontational naming accuracy and response time in people with mild to moderate aphasia compared with adults without aphasia. We hypothesized that negative and positive emotions would facilitate naming for people with aphasia but lead to slower responses for adults with no aphasia.

Method: Eight participants with mild to moderate aphasia, 15 older adults, and 17 young adults completed a confrontational naming task across three conditions (positive, negative, neutral) in an ABA case series design. Immediately following each naming condition, participants self-reported their perceived arousal and pleasure. Accuracy and response time were …

Using Legos® In Research Facilitation: An Advanced Scripted Research Method, Samuel W. Root

International Journal of Transpersonal Studies Advance Publication Archive

Transpersonal research methods can help individuals access useful information and material that typically reside out of conscious awareness. The playful activity of LEGO® block-building can be adapted for research purposes and used to overcome research impasses, for example. This paper presents a novel transpersonal LEGO® building process for facilitation in each of the four major phases of research. Readers are provided with a 6-step script that takes between 30 minutes and 1 hour to complete. Steps include: Prepare to Exercise; Set Intentions; Build While Intending Solution; Appreciate/Take In; Project and Actively Imagine; and Reflect and Ease Out. Future studies could …

Eye Movement And Pupil Measures: A Review, Bhanuka Mahanama, Yasith Jayawardana, Sundararaman Rengarajan, Gavindya Jayawardena, Leanne Chukoskie, Joseph Snider, Sampath Jayarathna

Computer Science Faculty Publications

Our subjective visual experiences involve complex interaction between our eyes, our brain, and the surrounding world. It gives us the sense of sight, color, stereopsis, distance, pattern recognition, motor coordination, and more. The increasing ubiquity of gaze-aware technology brings with it the ability to track gaze and pupil measures with varying degrees of fidelity. With this in mind, a review that considers the various gaze measures becomes increasingly relevant, especially considering our ability to make sense of these signals given different spatio-temporal sampling capacities. In this paper, we selectively review prior work on eye movements and pupil measures. We first …
