Common processes may contribute to extinction and habituation. J Gen Psychol 129:364-400 Evidence from Davis Lab (animals) Extinction training conducted very shortly after fear conditioning (10 min) seems to prevent all the classic signs of relapse: – reinstatement – context specificity – spontaneous recovery Opportunity Unlike other psychiatric disorders, the precipitant for adult PTSD is a known event, allowing for immediate intervention, presenting the potential to prevent, and ultimately eliminate for many, the occurrence of this most serious condition. Early Interventions Early Intervention Conclusions • Early interventions may interfere with natural recovery • No evidence for which early interventions help • Need to have right amount of exposure and arousal for optimum response • Later early interventions (ASD, weeks later) are effective at preventing the development of PTSD (Foa, Bryant) “Effects of Early Psychological Intervention to Prevent PTSD” Study Goals Short-term Goal: Can exposure therapy in the immediate aftermath of trauma prevent the development of PTSD?

  • Disrupted Habituation in the Early Stage of Psychosis
    Biological Psychiatry: CNNI Archival Report Disrupted Habituation in the Early Stage of Psychosis Suzanne N. Avery, Maureen McHugo, Kristan Armstrong, Jennifer U. Blackford, Neil D. Woodward, and Stephan Heckers ABSTRACT BACKGROUND: Learning and memory are impaired in schizophrenia. Some theories have proposed that one form of memory, habituation, is particularly impaired. Preliminary evidence suggests that memory impairment is associated with failed hippocampal habituation in patients with chronic schizophrenia. We studied how abnormal habituation of the hippocampus is related to relational memory deficits in the early stage of psychosis. METHODS: We measured hippocampal activity in 62 patients with early psychosis and 70 healthy individuals using functional magnetic resonance imaging. Habituation was defined as the slope of functional magnetic resonance imaging signal change to repeated presentations of faces and objects. Relational memory ability was measured as the slope of preferential viewing during a face-scene pair eye movement task outside the scanner. RESULTS: Patients with early psychosis showed impaired relational memory (p , .001) and less hippocampal habituation to objects (p = .01) than healthy control subjects. In the healthy control group, better relational memory was associated with faster anterior hippocampal habituation (faces, r = 2.28, p = .03). In contrast, patients with early psychosis showed no brain-behavior relationship (r = .12, p = .40). CONCLUSIONS: We found evidence for disrupted hippocampal habituation in the early stage of psychosis along with an altered association between hippocampal habituation and relational memory ability. These results suggest that neural habituation may provide a novel target for early cognitive interventions in psychosis. Keywords: First episode, Hippocampus, Novelty, Relational memory, Schizophrenia, Visual cortex https://doi.org/10.1016/j.bpsc.2019.06.007 Repetition is one of the most familiar memory tools.

  • Conditioning Trial Duration Affects Ethanol-Induced Conditioned Place Preference in Mice
    Animal Leaming & Behavior 1992, 20 (2), 187-194 Conditioning trial duration affects ethanol-induced conditioned place preference in mice CHRISTOPHER L. CUNNINGHAM and LIESL K. PRATHER Oregon Health Seiences University, Portland, Oregon The present experiments were designed to determine the efIect of conditioning trial duration on strength of ethanol-induced conditioned place preference in mice. In a counterbalanced, dif­ ferential conditioning procedure, DBA/2J mice received four pairings of a distinctive tactile (floor) stimulus with injection of ethanol (2 g/kg); a different floor stimulus was paired with saline. Dif­ ferent groups were exposed to the floor stimuli for 5, 15, or 30 min after injection. Conditioned place preference was inversely related to trial duration, with mice in the 5-, 15-,and 30-min groups, spending 83%,74%, and 66% oftheir time, respectively, on the ethanol-paired floor during a choice test. This outcome was replicated in a second experiment, which also showed that context famil­ iarity can influence conditioned place preference. In general, these findings suggest that ethanol's rewarding efIect is greatest shortly after injection. Study of the rewarding pbarmacological effect of 1989; van der Kooy, O'Shaughnessy, Mucba, & Kalant, ethanol has been limited primarily to examination of 1983).

Wilhelm Department of Clinical Psychology and Psychotherapy, Institute for Psychology, University of Basel, Missionsstrasse 60/62, CH-4055 Basel, Switzerland Received 29 August 2006; received in revised form 26 February 2007; accepted 28 February 2007 Abstract Aversive conditioning has been proposed as an important factor involved in the etiology of posttraumatic stress disorder (PTSD). However, it is not yet fully understood exactly which learning mechanisms are characteristic for PTSD. PTSD patients (n ¼ 36), and healthy individuals with and without trauma exposure (TE group, n ¼ 21; nTE group, n ¼ 34), underwent a differential fear conditioning experiment consisting of habituation, acquisition, and extinction phases. An electrical stimulus served as the unconditioned stimulus (US), and two neutral pictures as conditioned stimuli (CSþ, paired; CSÀ, unpaired). Conditioned responses were quantified by skin conductance responses (SCRs), subjective ratings of CS valence and US-expectancy, and a behavioural test. In contrast to the nTE group, PTSD patients showed delayed extinction of SCRs to the CSþ. Online ratings of valence and US-expectancy as well as the behavioural test confirmed this pattern. These findings point to a deficit in extinction learning and highlight the role of affective valence appraisals and cognitive biases in PTSD. In addition, there was some evidence that a subgroup of PTSD patients had difficulties in learning the CS–US contingency, thereby providing preliminary evidence of reduced discrimination learning.

  • CBT for OCD: Habituation Or Cognitive Shift?
    The Cognitive Behaviour Therapist (2014), vol. 7, e6, page 1 of 16 PRACTICE ARTICLE doi:10.1017/S1754470X14000063 CBT for OCD: habituation or cognitive shift? Lottie Morris1∗ and Jim Nightingale2 1Department of Psychology, 6W 0.9, University of Bath, Claverton Down, Bath, UK 2Psychological Therapies Service, Cedar House, Blackberry Hill Hospital, Manor Road, Fishponds, Bristol, UK Received 30 July 2013; Accepted 11 April 2014 Abstract. Cognitive Behavioural Therapy (CBT) including Exposure and Response Prevention (ERP) is recommended by NICE as the psychological treatment of choice for obsessive compulsive disorder (OCD). Twenty-five percent of OCD patients refuse ERP, and many psychologists advocate formulation-driven cognitive therapy, including ERP, as opposed to ERP alone. However, a recent meta-analysis suggested there is insufficient evidence to suggest ERP is improved by cognitive methods. This paper proposes to contribute to this debate by providing a detailed description of the treatment of a patient with intrusive cognitions of a sexual nature, who was treated successfully using behavioural experiments designed to test cognitions, rather than ERP. This is, arguably, the way in which most cognitive behavioural therapists would work with someone with OCD. However, this approach is not reflected in the literature at present. The authors report the patient’s feedback that therapeutic change was brought about through cognitive shift, as a result of the formulation-driven behavioural experiments. Key words: Behavioural cognitive therapy, belief modification, CBT, cognition, OCD. Theoretical and research basis for therapy This paper begins by reviewing pertinent literature relating to this case. Anna’s presenting problem is then described, along with the cognitive behavioural hypotheses developed during treatment.
