Predictors of Response to Web-Based Cognitive Behavioral Therapy With High-Intensity Face-to-Face Therapist Guidance for Depression: A Bayesian Analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-06)
Background: Several studies have demonstrated the effect of guided Internet-based cognitive behavioral therapy (ICBT) for depression. However, ICBT is not suitable for all depressed patients and there is a considerable level of nonresponse. Research on predictors and moderators of outcome in ICBT is inconclusive. Objective: This paper explored predictors of response to an intervention combining the ...
Toward a model-based cognitive neuroscience of mind wandering
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-03)
People often ‘‘mind wander” during everyday tasks, temporarily losing track of time, place, or current task goals. In laboratory-based tasks, mind wandering is often associated with performance decrements in behavioral variables and changes in neural recordings. Such empirical associations provide descriptive accounts of mind wandering – howit affects ongoing task performance – but fail to ...
Linking brain networks and behavioral variability to different types of mind-wandering

Response-Retrieval in Identity Negative Priming is Modulated by Temporal Discriminability
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
Reaction times to previously ignored information are often delayed, a phenomenon referred to as negative priming (NP). Rothermund et al. (2005) proposed that NP is caused by the retrieval of incidental stimulus-response associations when consecutive displays share visual features but require different responses. In two experiments we examined whether the features (color, shape) that reappear in ...
A Neural Model of Mind Wandering
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-06-25)
The role of the default-mode network (DMN) in the emergence of mind wandering and task-unrelated thought has been studied extensively. In parallel work, mind wandering has been associated with neuromodulation via the locus coeruleus (LC) norepinephrine (LC-NE) system. Here we propose a neural model that links the two systems in an integrative framework. The model attempts to explain how dynamic ...
Placebo Intervention Enhances Reward Learning in Healthy Individuals
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-23)
According to the placebo-reward hypothesis, placebo is a reward-anticipation process that increases midbrain dopamine (DA) levels. Reward-based learning processes, such as reinforcement learning, involves a large part of the DA-ergic network that is also activated by the placebo intervention. Given the neurochemical overlap between placebo and reward learning, we investigated whether verbal ...
Data from ‘Placebo Enhances Reward Learning in Healthy Individuals’
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-20)
This dataset contains three repeated measures of a standard reward-based reinforcement-learning task from 29 healthy male individuals who participated in three experimental sessions exploring cognitive placebo effects on reward learning. The dataset includes behavioural data (accuracy, reaction times) during learning and transfer, estimates of model-free computational analysis, self-reported arousal ...
Effects of transcranial direct current stimulation for treating depression: A modeling study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-28)
<p><i>Background</i>: Transcranial direct current stimulation (tDCS) above the left dorsolateral prefrontal cortex (lDLPFC) has been widely used to improve symptoms of major depressive disorder (MDD). However, the effects of different stimulation protocols in the entire frontal lobe have not been investigated in a large sample including patient data.</p> <p><i>Methods</i>: We used 38 head ...
On the efficiency of neurally-informed cognitive models to identify latent cognitive states
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-25)
Psychological theory is advanced through empirical tests of predictions derived from quantitative cognitive models. As cognitive models are developed and extended, they tend to increase in complexity–leading to more precise predictions–which places concomitant demands on the behavioral data used to discriminate between candidate theories. To aid discrimination between cognitive models and, more ...
Evidence for Cognitive Placebo and Nocebo Effects in Healthy Individuals
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-28)
Inactive interventions can have significant effects on cognitive performance. Understanding the generation of these cognitive placebo/nocebo effects is crucial for evaluating the cognitive impacts of interventional methods, such as non-invasive brain stimulation (NIBS). We report both cognitive placebo and nocebo effects on reward-based learning performance induced using an active sham NIBS protocol, ...
