Seeking under threat of adversity: assessing control over reward pursuit in rats.

Rationale: Substance use disorder (SUD) is a chronic relapsing brain disorder that is characterised by loss of control over substance use. A variety of rodent models employing punishment setups have been developed to assess loss of control over substance use, i.e.

A Circle-Drawing Task for Studying Reward-Based Motor Learning in Children and Adults.

Childhood is an obvious period for motor learning, since children's musculoskeletal and nervous systems are still in development. Adults adapt movements based on reward feedback about success and failure, but it is less established whether school-age children also exhibit such reward-based motor learning. We designed a new 'circle-drawing' task suitable for assessing reward-based motor learning in both children (7-17 years old) and adults (18-65 years old).

The bias and precision of reporting the average age of human participants.

Most research papers in psychology study the behaviour of a sample of participants. To characterise this sample, authors report various characteristics, frequently including the mean age and the associated standard deviation. However, based on reports from authors who publish in Acta Psychologica and from respondents on X/Twitter, the present paper shows that some authors use rounded-down ages whereas others don't, which lead to an uncertainty of 0.
