Media multitasking, impulsivity and dual task ability
(Elsevier, 2018-11-09)With recent developments in technology, media multitasking is an ever-increasing phenomenon. Although most studies associate media multitasking with high impulsivity and poorer cognitive performance, findings in the ... -
Using Explicit Case Formulation to Improve Cognitive Processing Therapy for PTSD
(Elsevier, 2018-04-18)We investigated the utility of explicit case formulation (CF) within Cognitive Processing Therapy (CPT) for individuals with posttraumatic stress disorder (PTSD). An uncontrolled pre-posttreatment design was used. Participants ... -
Investigation of sex differences in delusion-associated cognitive biases
(Elsevier, 2018-12-24)In the past few decades, sex differences have been identified in a number of clinical, cognitive and functional outcomes in patients with schizophrenia spectrum disorders. However, to date, sex differences in higher-order ... -
Impaired mismatch negativity to frequency deviants in individuals at ultra-high risk for psychosis, and preliminary evidence for further impairment with transition to psychosis
(Elsevier, 2017-11-11)Background There is evidence to suggest that people with established psychotic disorders show impairments in the mismatch negativity induced by a frequency-deviant sound (fMMN), and that these impairments worsen with ... -
Neurophysiological evidence of efference copies to inner speech
(eLife Sciences, 2017-12-04)Efference copies refer to internal duplicates of movement-producing neural signals. Their primary function is to predict, and often suppress, the sensory consequences of willed movements. Efference copies have been almost ... -
Cross‐modal symbolic processing can elicit either an N2 or a protracted N2/N400 response
(Wiley, 2016-03-26)A cross‐modal symbolic paradigm was used to elicit EEG activity related to semantic incongruence. Twenty‐five undergraduate students viewed pairings of visual lexical cues (e.g., DOG) with congruent (50% of trials) or ... -
Effects of Outcome Predictability on Human Learning
(Frontiers, 2017-04-05)Cue-outcome learning is a cornerstone of intelligent action. Learning that a stimulus (the cue) can be used to predict a second event (the outcome) affords adaptive decision making. If an animal can use environmental cues ... -
Outcome predictability biases cued search
(American Psychological Association, 2018)Within the domain of associative learning, there is substantial evidence that people (and other animals) select among environmental cues on the basis of their reinforcement history. Specifically, people preferentially ... -
Desirable leadership attributes are preferentially associated with women: A quantitative study of gender and leadership roles in the Australian workforce
(Sage Journals, 2018-09-19)Women are under-represented globally in leadership roles. One theory suggests that this imbalance is due to a mismatch between the qualities women are perceived to have, and the qualities desired in business leaders. Yet, ... -
Compound Stimulus Presentation Does Not Deepen Extinction in Human Causal Learning
(Frontiers, 2017-02-09)Models of associative learning have proposed that cue-outcome learning critically depends on the degree of prediction error encountered during training. Two experiments examined the role of error-driven extinction learning ... -
Do meta-cognitive beliefs affect meta-awareness of intrusive thoughts about trauma?
(Elsevier, 2016-10-24)Background and Objectives People exposed to trauma often experience intrusive thoughts and memories about that event. Research examining people's responses to trauma assumes that people can accurately notice the occurrence ... -
Meta-awareness and the involuntary memory spectrum: Reply to Meyer, Otgaar, and Smeets (2015)
(Elsevier, 2015-03-30)In their commentary, Meyer, Otgaar, and Smeets (2015) raise several important issues about the definitions, characteristics and applications of various involuntary cognitive phenomena. Here we respond to the comments of ... -
Trauma-related versus positive involuntary thoughts with and without meta-awareness
(Elsevier, 2016-10-07)In earlier work, we asked subjects to report involuntary thoughts relating to a trauma film and also probed subjects periodically. Subjects often reported involuntary thoughts in response to probes, suggesting they lacked ... -
Explaining Memory Amplification: Is It All About the Test Format?
(Sage Journals, 2017-12-08)Trauma-exposed people commonly exhibit a “memory amplification” effect, endorsing exposure to more traumatic events over time. Studies reporting this phenomenon have typically relied on checklists, where participants read ... -
Self-report may underestimate trauma intrusions
(Elsevier, 2014-06-30)Research examining maladaptive responses to trauma routinely relies on spontaneous self-report to index intrusive thoughts, which assumes people accurately recognize and report their intrusive thoughts. However, “mind-wandering” ... -
Insomnia and mortality: A meta-analysis
(Elsevier, 2018-11-11)The purpose of this review was to evaluate the strength of evidence for a relationship between risk of mortality and frequent and ongoing insomnia using a meta-analytic strategy. Seventeen studies, including a total of ... -
Semantic prediction-errors are context-dependent: An ERP study
(Elsevier, 2018-10-31)The human brain is an efficient, adaptive, and predictive machine, constructing a generative model of the environment that we then perceive and become conscious of. Here, we show that different types of prediction-errors ... -
Co-expression network analysis of peripheral blood transcriptome identifies dysregulated protein processing in endoplasmic reticulum and immune response in recurrent MDD in older adults
(Elsevier, 2018-10-01)The molecular factors involved in the pathophysiology of major depressive disorder (MDD) remain poorly understood. One approach to examine the molecular basis of MDD is co-expression network analysis, which facilitates the ... -
Sleep duration and risk-taking in adolescents: a systematic review and meta-analysis
(Elsevier, 2018-03-21)Risk-taking is associated with increased morbidity and mortality among adolescents, with insufficient sleep a potential factor contributing to heightened risk-taking propensity in this age group. A systematic review of the ... -
Asymmetric neural responses for facial expressions and anti-expressions
(Elsevier, 2018-09-05)Face recognition requires identifying both the invariant characteristics that distinguish one individual from another and the variations within the individual that correspond to emotional expressions. Both have been ...
