Journal ArticleDOI
Reliability and validity of a new Medication Adherence Rating Scale (MARS) for the psychoses.
TL;DR: Using the partial credit version of the Item Response Theory measurement model, the DAI was refined with the aim of greater validity and clinical utility and appears to be a valid and reliable measure of compliancy for psychoactive medications.
Journal ArticleDOI
Classification of EEG signals using the wavelet transform
TL;DR: An artificial neural network technique together with a feature extraction technique, viz., the wavelet transform, for the classification of EEG signals, which provides a potentially powerful technique for preprocessing EEG signals prior to classification.
Journal ArticleDOI
Reduced connectivity of the auditory cortex in patients with auditory hallucinations: a resting state functional magnetic resonance imaging study
Maria Gavrilescu,Susan L. Rossell,Geoffrey W. Stuart,Tracey Shea,Hamish Innes-Brown,Katherine R. Henshall,Colette M. McKay,Alex Sergejew,David L. Copolov,Gary F. Egan +9 more
TL;DR: A trait deficit specific to schizophrenia patients with a history of auditory hallucinations is identified, expected to result in the disruption of multiple auditory functions, for example, the integration of basic auditory information between hemispheres and higher-order language processing abilities.
Journal ArticleDOI
Nonlinear considerations in EEG signal classification
TL;DR: It is shown that in certain cases, the nonlinearity of the EEG signals is an important factor that ought to be taken into consideration during preprocessing of the signals prior to the classification task.
Journal ArticleDOI
Emotional prosodic processing in auditory hallucinations.
Tracey Shea,Tracey Shea,Alex Sergejew,Alex Sergejew,Denis K Burnham,Caroline Jones,Caroline Jones,Susan L. Rossell,David L. Copolov,Gary F. Egan +9 more
TL;DR: Patients experiencing auditory hallucinations were not as successful in recognising and using prosodic cues as the non-hallucinating patients, consistent with Cutting's hypothesis, that prosodic dysfunction may mediate the misattribution of auditory hallucinations.
