“…Various studies have also revealed that task load impacts the balance between primary task engagement and the capacity to remain responsive to auditory stimuli (e.g., Berti & Schröger, 2003;Zhu et al, 2022). In numerous studies, the primary task's difficulty is manipulated and its impact on the passive or active processing of auditory stimuli is examined via the analysis of event-related potentials (ERPs) (e.g., Ghani et al, 2020;Gibson et al, 2019;Giraudet, Imbert, et al, 2015;Kramer et al, 1995;M. M. Swerdloff & L. J. Hargrove, 2020;Raabe et al, 2005;Ullsperger et al, 2001).…”

“…This was selected due to its ability to measure across short periods of time, it not causing practical issues when used alongside GSR and evidence of it accurately measuring anxiety in the literature Wiedemann et al (1999). EEG signals were collected at 500 Hz from the F3, F4, F7 and F8 sites using the 10-20 system Homan et al (1987) after impedance checks showed resistance to be less than 20kOhm, a threshold successfully demonstrated in previous studies Luck (2014); Gibson et al (2018). Data was pre-processed in EEG Lab Delorme and Makeig (2004) with visual inspections of 2 s, overlapped epochs performed for artefact rejection, a range recommended in the works of Smith et al Smith et al (2017).…”

A proof of concept virtual reality system is presented that integrates ultrasonic feedback sensations to provide a demonstrative virtual reality exposure therapy environment containing multiple scenarios with virtual spiders. This system and environment were utilised to conduct a study containing 35 participants with the goal of investigating the effect the environment could have on their level of anxiety. This level of anxiety was measured in three different forms: changes in frontal asymmetry analysis of EEG data, changes in skin conductance levels and subjective units of distress. The Fear of Spiders Questionnaire was used to determine which participants in the study reported to be moderately afraid of spiders. For these participants all three measurement forms for anxiety showed statistically significant increases in a comparison between baseline and scenarios with the virtual spiders. A statistically significant correlation between scores on the Fear of Spiders Questionnaire and changes in anxiety shows the system to have had a greater effect on the anxiety levels of those who were more afraid of spiders, than those who were not. There was also a statistically significant correlation discovered between immersion and increase in anxiety, highlighting the significance of immersion in future virtual reality exposure therapy applications.

Conventional performance metrics fail to offer highresolution evaluation of learning and memory during training tasks; the P300 component of the event-related potential (ERP) is a promising tool for enhancing the assessment of training quality in virtual environments, but this technique is yet to be investigated. A driver training simulator and scenario were developed to explore the capability of the P300 for this purpose. A user study was conducted with 32 participants divided into 2 groups objectively determined by driving performance scores, thus enabling observations of the P300 response to be equated to varying levels of learning and memory. Participant electroencephalogram (EEG) data was recorded during the procedure, which was post-processed to filter and extract ERPs to capture neural responses to specific events in the virtual training scenario. These were combined to produce a result for each participant, which was then grand averaged to create an overall ERP for each group. Across the eight electrode sites statistically significant differences were found between the grand average waveforms of the two groups, with high memory retention producing significantly greater peak to peak amplitude (U = 9.00, p = .045), peak latency (U = 0.00, p < .001), and positive area (U = 13.00, p = .05) of the waveform than low memory retention. The evidenced relationship between the P300 response and working memory in this context suggests it has the potential for monitoring learning and memory in stimulus-driven virtual training systems.
