Dopamine and temporal discounting: revisiting pharmacology and individual differences Open
Disorders characterised by changes in dopamine (DA) neurotransmission are often linked to changes in the temporal discounting of future rewards. Likewise, pharmacological manipulations of DA neuro-transmission in healthy individuals modula…

Pharmacological Enhancement of Dopamine Neurotransmission Does Not Affect Illusory Pattern Perception Open
Psychotic symptoms and delusional beliefs have been linked to dopamine transmission in both healthy and clinical samples and are assumed to result at least in part from perceiving illusory patterns in noise. However, the existing literatur…

Loot box content is associated with increased user engagement for YouTube gaming videos Open
Video games frequently contain loot boxes, i.e. purchasable randomised virtual in-game items which share structural similarities with gambling. On YouTube©, there are multi-million subscriber video streams focusing on gaming, and many vide…

Large-Scale Web Scraping for Problem Gambling Research: A Case Study of COVID-19 Lockdown Effects in Germany Open
The COVID-19 pandemic and the measures to prevent its spread have had a negative impact on substance use behaviour. It is likely that social distancing and lockdown measures have also altered gambling behaviour, for instance shifting from …

Accurate machine learning prediction of sexual orientation based on brain morphology and intrinsic functional connectivity Open
Background Sexual orientation in humans represents a multilevel construct that is grounded in both neurobiological and environmental factors. Objective Here, we bring to bear a machine learning approach to predict sexual orientation from g…

Large-scale web scraping for problem gambling research: a case study of COVID-19 lockdown effects in Germany Open
The COVID-19 pandemic and the measures to prevent its spread have had a negative impact on substance use behaviour and posed a special threat for individuals at risk. Problem gambling is a major public health concern, and it is likely that…

Motor response vigour and visual fixation patterns reflect subjective valuation during intertemporal choice Open
Value-based decision-making is of central interest in cognitive neuroscience and psychology, as well as in the context of neuropsychiatric disorders characterised by decision-making impairments. Studies examining (neuro-)computational mech…

Parameter and Model Recovery of Reinforcement Learning Models for Restless Bandit Problems Open
Multi-armed restless bandit tasks are regularly applied in psychology and cognitive neuroscience to assess exploration and exploitation behavior in structured environments. These models are also readily applied to examine effects of (virtu…

Exploring Sex Differences in the Neural Correlates of Self-and Other-Referential Gender Stereotyping Open
While general self-referential processes and their neural underpinnings have been extensively investigated with neuroimaging tools, limited data is available on sex differences regarding self- and other-referential processing. To fill this…
