A validation of Emotiv EPOC Flex saline for EEG and ERP research.
Nikolas Williams,Genevieve McArthur,Bianca de Wit,George Ibrahim,Nicholas A. Badcock,Nicholas A. Badcock +5 more
TL;DR: The saline version of the Emotiv EPOC Flex captures data similar to that of a research-grade EEG system that can be used to measure reliable auditory and visual research-quality ERPs and is sensitive to changes in alpha oscillations.

Belief, delusion, hypnosis, and the right dorsolateral prefrontal cortex: A transcranial magnetic stimulation study.
Max Coltheart,Rochelle E. Cox,Paul F. Sowman,Hannah L. Morgan,Amanda J. Barnier,Robyn Langdon,Emily Connaughton,Lina Teichmann,Nikolas Williams,Vince Polito +9 more
TL;DR: Results imply a role for rDLPFC in the cognitive process of belief evaluation, as is proposed in the two-factor theory of delusion, and are consistent with a conception of the acceptance of a hypnotic suggestion as involving suspension of disbelief.

Should I Trust You? Autistic Traits Predict Reduced Appearance-Based Trust Decisions
Jasmine Jean Hooper,Clare A. M. Sutherland,Louise Ewing,Louise Ewing,Robyn Langdon,Nathan Caruana,Emily Connaughton,Nikolas Williams,Jayden Greenwell-Barnden,Gillian Rhodes +9 more
TL;DR: The results identify autistic traits as an important source of individual variation in the use of facial impressions to guide behaviour and suggest failure to use these impressions could potentially represent rational behaviour, given their limited validity.
It's all about time: precision and accuracy of Emotiv event-marking for ERP research.
TL;DR: In this paper, the authors investigated the timing reliability of event-marking solutions used with Emotiv commercial EEG systems and established a jitter threshold (i.e., the point at which jitter made an eventmarking method unreliable) to determine when an event should appear in the EEG data.

Appearance‐based trust processing in schizophrenia
Clare A. M. Sutherland,Clare A. M. Sutherland,Gillian Rhodes,Nikolas Williams,Emily Connaughton,Louise Ewing,Nathan Caruana,Robyn Langdon +7 more
TL;DR: People with schizophrenia made very similar facial trustworthiness impressions to healthy controls and also used facial appearance to guide trust decisions similarly to controls, but people with schizophrenia failed to use actual partner fairness to guide their financial decisions in the Trust Game, unlike controls.
