  1. Monothematic Delusions: Towards a Two-Factor Account.Martin Davies, Max Coltheart, Robyn Langdon & N. Breen - 2001 - Philosophy, Psychiatry and Psychology 8 (2-3):133-58.
    We provide a battery of examples of delusions against which theoretical accounts can be tested. Then, we identify neuropsychological anomalies that could produce the unusual experiences that may lead, in turn, to the delusions in our battery. However, we argue against Maher’s view that delusions are false beliefs that arise as normal responses to anomalous experiences. We propose, instead, that a second factor is required to account for the transition from unusual experience to delusional belief. The second factor in the (...)

    Folie À Deux and its Lessons for Two-Factor Theorists.Robyn Langdon - 2013 - Mind and Language 28 (1):72-82.
    In folie à deux, a ‘primary’ patient transmits a delusional belief to one or more ‘secondary’ patients who then adopt and share the belief. This paper applies the two-factor theory of delusion to retrospectively analyse published cases of folie à deux. Lessons from this retrospective analysis include, firstly, that two-factor theorists need to shift their focus from endogenous processes to consider the exogenous source of delusional content in most secondaries. Secondly, secondaries who come to share the belief via normal processes (...)

    The Fregoli Delusion: A Disorder of Person Identification and Tracking.Robyn Langdon, Emily Connaughton & Max Coltheart - 2014 - Topics in Cognitive Science 6 (4):615-631.
    Fregoli delusion is the mistaken belief that some person currently present in the deluded person's environment is a familiar person in disguise. The stranger is believed to be psychologically identical to this known person even though the deluded person perceives the physical appearance of the stranger as being different from the known person's typical appearance. To gain a deeper understanding of this contradictory error in the normal system for tracking and identifying known persons, we conducted a detailed survey of all (...)

    Understanding Minds and Understanding Communicated Meanings in Schizophrenia.Robyn Langdon, Martin Davies & Max Coltheart - 2002 - Mind and Language 17 (1-2):68-104.
    Cognitive neuropsychology is that branch of cognitive psychology that investi- gates people with acquired or developmental disorders of cognition. The aim is to learn more about how cognitive systems normally operate or about how they are normally acquired by studying selective patterns of cognitive break- down after brain damage or selective dif?culties in acquiring particular cogni- tive abilities. In the early days of modern cognitive neuropsychology, research focused on rather basic cognitive abilities such as speech comprehension or production at the (...)

    A Laboratory Analogue of Mirrored-Self Misidentification Delusion: The Role of Hypnosis, Suggestion, and Demand Characteristics.Michael H. Connors, Amanda J. Barnier, Robyn Langdon, Rochelle E. Cox, Vince Polito & Max Coltheart - 2013 - Consciousness and Cognition 22 (4):1510-1522.
    Mirrored-self misidentification is the delusional belief that one's own reflection in the mirror is a stranger. In two experiments, we tested the ability of hypnotic suggestion to model this condition. In Experiment 1, we compared two suggestions based on either the delusion's surface features (seeing a stranger in the mirror) or underlying processes (impaired face processing). Fifty-two high hypnotisable participants received one of these suggestions either with hypnosis or without in a wake control. In Experiment 2, we examined the extent (...)

    Masked and Unmasked Priming in Schizophrenia.Robyn Langdon, Matthew Finkbeiner, Michael H. Connors & Emily Connaughton - 2013 - Consciousness and Cognition 22 (4):1206-1213.
    Dehaene et al. (2003) showed an absence of conscious, but not masked, conflict effects when patients with schizophrenia performed a number-categorisation priming task. We aimed to replicate these influential results using a different word-categorisation priming task. Counter to Dehaene et al.'s findings, 21 patients and 20 healthy controls showed similar congruence effects for both masked and visible primes. Within patients, a reduced congruence effect for visible primes associated with longer duration of illness and more severe behavioural disorganisation. Patients, unlike controls, (...)

    Pathological and Non-Pathological Factors in Delusional Misbelief.Robyn Langdon - 2009 - Behavioral and Brain Sciences 32 (6):527-528.
    In their pursuit of adaptively biased misbelief-making systems, McKay & Dennett (M&D) describe a putative doxastic shear-pin system which enables misbeliefs to form in situations of extreme psychological stress. Rather than discussing their argument, I consider how this shear-pin system might combine with both pathological belief-making ( breakdowns caused by neuropathy) and normal belief-making to explain a spectrum of delusions.

    The Experience of Altered States of Consciousness in Shamanic Ritual: The Role of Pre-Existing Beliefs and Affective Factors.Vince Polito, Robyn Langdon & Jac Brown - 2010 - Consciousness and Cognition 19 (4):918--925.
    Much attention has been paid recently to the role of anomalous experiences in the aetiology of certain types of psychopathology, e.g. in the formation of delusions. We examine, instead, the top-down influence of pre-existing beliefs and affective factors in shaping an individual’s characterisation of anomalous sensory experiences. Specifically we investigated the effects of paranormal beliefs and alexithymia in determining the intensity and quality of an altered state of consciousness . Fifty five participants took part in a sweat lodge ceremony, a (...)

    Hypo- or Hyper-Mentalizing: It All Depends Upon What One Means by “Mentalizing”.Robyn Langdon & Jon Brock - 2008 - Behavioral and Brain Sciences 31 (3):274-275.
    By conceiving of autism and psychosis as diametrically opposite phenotypes of underactive and overactive mentalizing, respectively, Crespi & Badcock (C&B) commit themselves to a continuum view of intercorrelated mentalizing functions. This view fails to acknowledge dissociations between mentalizing functions and that psychotic people show a mixture of both hypo- and hyper-mentalizing.
