Purpose: Augmentative and alternative communication (AAC) systems are important to support communication for individuals with complex communication needs. A recent addition to AAC system options is the brain-computer interface (BCI). This study aimed to compare the clinical application of the P300 speller BCI with two more common AAC systems, the…

Face recognition is a fundamental function that requires holistic processing. Differences in face processing have been consistently identified in autistic children, but it is unknown whether these differences persist across the adult lifespan. Using event-related functional magnetic resonance imaging, we measured holistic face processing with a…

Dendritic regulatory BC1 RNA is a non-protein-coding (npc) RNA that operates in the translational control of gene expression. The absence of BC1 RNA in BC1 knockout (KO) animals causes translational dysregulation that entails neuronal phenotypic alterations including prolonged epileptiform discharges, audiogenic seizure activity in vivo, and…

The context preexposure facilitation effect (CPFE) is a contextual fear conditioning paradigm in which learning about the context, acquiring the context-shock association, and retrieving/expressing contextual fear are temporally dissociated into three distinct phases. In contrast, learning about the context and the context-shock association…

The insular cortex (IC) is required for conditioned taste aversion (CTA) retrieval. However, it remains unknown which cortical neurotransmitters levels are modified upon CTA retrieval. Using in vivo microdialysis, we observed that there were clear elevations in extracellular glutamate, norepinephrine, and dopamine in and around the center of the…

We characterized the transcriptional response accompanying maintenance of long-term sensitization (LTS) memory in the pleural ganglia of "Aplysia californica" using microarray (N = 8) and qPCR (N = 11 additional samples). We found that 24 h after memory induction there is strong regulation of 1198 transcripts (748 up and 450 down) in a…

Social cognition is a set of complex processes that mediate much of human behavior. The development of these skills is related to and interdependent on other cognitive processes, particularly inhibitory control. Brain regions associated with inhibitory control and social cognition overlap functionally and structurally, especially with respect to…

Object representations from convolutional neural network (CNN) models of computer vision (LeCun, Bengio, & Hinton, 2015) were used to drive a cognitive model of decision making, the linear ballistic accumulator (LBA) model (Brown & Heathcote, 2008), to predict errors and response times (RTs) in a novel object recognition task in humans.…

This real-life story can be rationalised as an auto-ethnographic appreciation of the journey of Diane and I. The journey is new to us when it was once known and planned. The path has veered with new challenges realised since the "death sentence" was passed. This longitudinal research, is original and unique, drawing initially upon the…

The present study aimed to explore the neural-related mechanism of the creative evaluation process in individual with different levels of creativity. The time course of evaluation process for creative objects was monitored by event-related potentials (EPRs). Forty-five participants were divided into the high-creativity performance (HCP) group and…

Purpose: Complex posttraumatic stress disorder (CPTSD) is a multifaceted disorder, and the specific diagnostic criteria developed by the World Health Organization (WHO), which highlight symptoms of CPTSD (i.e., affect dysregulation, negative self-concept, disturbed relationships), that occur along with PTSD symptoms speak to this. Understanding…

Stuttering is a developmental speech disorder characterized by interruptions of fluency. A large body of research suggests that stuttering occurs due to a reduced ability to generate timing signals in order to sequence speech sounds. One piece of supporting evidence for this is that when speaking along with an external timing source like a…

The COVID-19 pandemic has interrupted education institutions in over 150 nations, affecting billions of students. Many governments have forced a transition in higher education from in-person to remote learning. After this abrupt, worldwide transition away from the classroom, some question whether online education will continue to grow in…

Prediction in language comprehension has become a key mechanism in recent psycholinguistic theory, with evidence from lexical prediction as a primary source. Less work has focused on whether comprehenders also make structural predictions above the lexical level. Previous research shows that processing is facilitated for syntactic structures which…

This dissertation describes a program of research encompassing three studies that focused on examining the effects of enhanced expectancies and perceptions of success on motor learning. OPTIMAL theory (Wulf & Lewthwaite, 2016) proposes that practice manipulations that enhance a learner's expectations for future successful outcomes lead to…
