Adding quetiapine to SRI in treatment-resistant obsessive-compulsive disorder: a randomized controlled treatment study
Fineberg, Naomi; Sivakumaran, T.; Roberts, A.; Gale, T.M. (2005)This study aimed to determine the efficacy and tolerability of adding quetiapine to a serotonin reuptake inhibitor in treatment-resistant obsessive-compulsive disorder (OCD). Twenty-one adult treatment-resistant OCD patients ... -
Analysis of Linear and Nonlinear dimensionality Reduction Methods for Gender Classification of Face Images
Buchala, S.; Davey, N.; Gale, T.M.; Frank, R. (2005-11)Data in many real world applications are high dimensional and learning algorithms like neural networks may have problems in handling high dimensional data. However, the Intrinsic Dimension is often much less than the ... -
Are placebo-controlled trials still important for obsessive compulsive disorder?
Fineberg, Naomi; Hawley, C.; Gale, T.M. (2006)The use of placebos as reference agents in randomised controlled trials for psychiatric disorders has come under question for ethical reasons. Alternative methods for validating the efficacy of new treatments exist, but ... -
Basic-level visual similarity and category specificity
Gale, T.M.; Laws, K.R.; Frank, R.; Leeson, V.C. (2003)The role of visual crowding in category deficits has been widely discussed (e.g., [Humphreys et al., 1988]; [Laws and Gale, 2002]; [Tranel et al., 1997]). Most studies have measured overlap at the superordinate level ... -
Category specific naming the visual properties of line drawn stimuli
Gale, T.M.; Laws, K.R. (2002)It has been argued that greater intra-category structural similarity for living things may make them more difficult to recognize and name (e.g. Humphreys et al., 1988). Nevertheless, the precise meaning and quantification ... -
Category-specific semantics in Alzheimer's dementia and normal aging?
Laws, K.R.; Gale, T.M.; Adlington, R.L.; Irvine, K.; Sthanakiya, S.; Moreno-Martínez, F.J. (2011)Category-specific deficits represent the archetypal illustration of domain-specific cognitive processes. These deficits describe individuals who, following certain types of neurological damage show dissociations in their ... -
Category-specificity can emerge from bottom-up visual characteristics: evidence from a modular neural network
Gale, T.M.; Laws, K.R. (2006)The role of bottom-up visual processes in category-speciWc object recognition has been largely unexplored. We examined the role of low-level visual characteristics in category speciWc recognition using a modular neural ... -
Comorbid depression in obsessive compulsive disorder (OCD) : Symptomatic differences to major depressive disorder
Fineberg, Naomi; Fourie, H.; Gale, T.M.; Sivakumaran, T. (2005)In this study, we compared the depressive symptom profile of a group of obsessive compulsive disorder (OCD) patients, with comorbid depression, to a group of patients with major depressive disorder (MDD). The two groups ... -
Comparing computational and human measures of visual similarity
Gale, T.M.; Sun, Yi.; Adams, R.G.; Davey, N. (World Scientific Publishing, 2005)There have been many attempts to quantify visual similarity within different categories of objects, with a view to using such measures to predict impaired recognition performance. Although many studies have linked measures ... -
Crowded and sparse domains in object recognition: consequences for categorisation and naming
Gale, T.M.; Laws, K.R.; Foley, K. (2006)Some models of object recognition propose that items from structurally crowded categories (e.g., living things) permit faster access to superordinate semantic information than structurally dissimilar categories (e.g., ... -
Defining remission by cut off score on the MADRS : selecting the optimal value
Hawley, C.; Gale, T.M.; Sivakumaran, T. (2002)Background: Remission from major depression may be conceptualised in terms of a cut-off score on an appropriate rating scale. Candidate values proposed hitherto have not been directly validated. Method: The relationship ... -
Dimensionality reduction of face images for gender classification
Buchala, S.; Davey, N.; Frank, R.; Gale, T.M. (2004) -
Do mental health professionals really understand probability Implications for risk assessment and evidence-based practice
Gale, T.M.; Hawley, C.; Sivakumaran, T. (2003) -
A domain specific deficit for foodstuffs in patients with Alzheimer's disease
Laws, K.R.; Leeson, V.C.; Gale, T.M. (2002)Although some studies have reported a category specific naming deficit in Alzheimer’s patients (invariably for living things), others have failed to replicate this finding (Laws et al., in press). Inconsistencies may partly ... -
The effect of 'masking' on picture naming
Laws, K.R.; Leeson, V.C.; Gale, T.M. (2002)It is frequently assumed that because compared to nonliving things, living things are less familiar, have lower name frequency, and are more visually complex, this makes them more difficult to name by patients and normal ... -
The effectiveness and utility of a simple protocol for the management of depression in primary care
Hawley, C.; Sivakumaran, T.; Munns, A.; Gale, T.M. (2005)Objective: In the UK, the use of protocols for the management of depression is set to increase in response to the National Service Framework for Mental Health. To date, there has been little evaluation of the utility of ... -
Evidence-based pharmacotherapy of obsessive-compulsive disorder
Fineberg, Naomi; Gale, T.M. (2005) -
Excessive daytime sleepiness in psychiatric disorders : prevalence, correlates and clinical significance
Hawley, C.; Gale, T.M.; Sivakumaran, T.; Paul, S.; Kondan, V.R.G.; Farag, A.; Shahzad, J. (2010)This study examined the prevalence of excessive daytime sleepiness, as measured by the Epworth Sleepiness Scale (ESS), in a cohort of adult psychiatric patients. A total of 300 psychiatric outpatients and an additional 300 ... -
Gender classification of face images: the role of global and feature-based information
Buchala, S.; Davey, N.; Frank, R.; Gale, T.M.; Loomes, M.J.; Kanakard, W. (2004) -
Global and Feature Based Gender Classification of Faces: A Comparison of Human Performance and Computational Models
Buchala, S.; Davey, N.; Gale, T.M.; Frank, R. (2005)Most computational models for gender classification use global information (the full face image) giving equal weight to the whole face area irrespective of the importance of the internal features. Here, we use a global and ...
