After being fully renovated and decorated with life-size artwork by Lennard Kok, ‘De Brug’ was officially reopened on the 12th of October 2021. To celebrate this, Tim was invited to give a 10-minute ‘TED-talk’ on the effects of a digital detox, together with three other FMG-scientists building bridges between other disciplines and to society: Willem Boterman (GPIO), Thijs Bol (Sociology) and Saar Mollen (Cw).

Neuropsycholoog Tim van Timmeren onderzoekt het effect van een digitale detox tegen een social media-overdosis
Dat jongeren veel tijd besteden aan social media, is bekend. Maar hoe erg is dat? Neuropsycholoog Tim van Timmeren onderzoekt hoe mensen de controle over social media gebruik kunnen terug winnen. Is de zogeheten ‘digitale detox’, oftewel tijdelijk geen social media meer gebruiken, een effectieve manier om gebruik te verminderen? En welk effect heeft zo’n detox op welzijn en slaap? Neuropsycholoog Tim van Timmeren doet er onderzoek naar.

Ineens lagen Facebook, Instagram en WhatsApp door een wereldwijde storing urenlang plat. Wat doet cold turkey af- kicken van sociale media met ons gemoed en gedrag? Tim van Timmeren sprak erover met Annemarie de Jong voor het Noordhollands Dagblad.

Tim is on the committee to organize this year’s ABC Networking Event to Reconnect Researchers!

After more than a year of little opportunity to connect with your co-workers and fellow ABC members, please join to meet and connect with other ABC members and other brain and cognition researchers in Amsterdam on the virtual grounds of Gathertown!

Tim gave a talk at the first-year symposium for all ‘Pharmacy’ students at the Rijksuniversiteit Groningen: “Habit or secret addiction? – the brain’s reward system”. Other speakers of the symposium were dr. Dorien Treur (UvA), emeritus prof. Wim van den Brink (Amsterdam UMC – AMC) and Prof. Scheurink (Rijksuniversiteit Groningen). In his talk, Tim presented gambling disorder as a prototypical behavioral addiction, and discussed possible other potential behavioral addictions.

Hoewel er in het verleden al veel onderzoek is gedaan naar de factoren die kunnen bijdragen aan gezond ouder worden en het versterken van veerkracht, is nog lang niet alles bekend. Vooral als het gaat om het samenspel van verschillende factoren, is nog veel te ontdekken. Deze online studie is dan ook bedoeld om unieke, onverwachte dynamieken bloot te leggen tussen leefstijlgewoontes, demografische, sociale, omgevings-, psychologische, psychosociale en cognitieve factoren die bijdragen aan succesvolle veroudering en veerkracht.

Anderhalve meter afstand houden vinden we steeds moeilijker worden. Vooral jongeren lijken er minder toe bereid. Investeer daarom nationaal in een alternatieve aanpak, betogen vier wetenschappers: nudging, waarmee het gedrag van mensen wordt beïnvloed door aanpassingen in hun omgeving.

Het houden van anderhalve meter afstand ging de afgelopen periode vaak goed, maar soms ook mis, met afgelopen weekend enkele incidenten op stranden en een demonstratie op de Dam als voorbeeld. Waarom vinden we afstand houden toch zo moeilijk, ook al weten we waarom het belangrijk is? Stadszaken.nl vroeg het aan gedragswetenschapper Sanne de Wit:

Tim van Timmeren was awarded the ABC Talent Grant in the April ’20 round of the Amsterdam Brain & Cognition Centre, UvA (PI: Sanne de Wit).  The project is entitled: The promises and perils of a ‘digital detox’: An integrated investigation of the role of craving, habits and corticostriatal pathways.

Many young adults spend 3-5 hours daily on social media and some indicate that they feel ‘addicted’, pointing to an emerging public health problem. The idea of a “digital detox” to regain control over social media use has become increasingly popular. However, the effectiveness of detox-interventions remains controversial. The promise of a detox is that it helps to break the habit, but the peril is that it could ultimately lead to intensified use as a consequence of “incubation of craving”. In this ABC Talent project, we aim to elucidate the effects of a digital detox on social media use, and the underlying mechanisms of habit and craving. During and following a detox intervention, we will apply Ecological Momentary Assessment of self-reported craving and automaticity and relate this to duration and frequency of social media use. Additionally, we will conduct an fMRI investigation of the mechanisms underlying a digital detox.

Hoe houden we het nieuwe ‘normale’ gedrag van afstand houden en handen wassen vol nu de publieke ruimte steeds meer open gaat? De mens is een gewoontedier en dat moeten we niet uit het oog verliezen. Zie het artikel van Sanne op de UvA-FMG site: www.uva.nl

Sanne obtained a replication grant from NWO to replicate the research by Lally et al. from 2010 into the time it takes for habits to form. The study by Lally et al. has been very influential, in science and in the media. The finding of median 66 days it took to form a new habit is often cited. The study will be replicated in four locations with a team of researchers (Jaap Murre, Lotte Brinkhof, Annette Horstmann, Paul Fletcher, Maik Bieleke, and Julia Schüler), on a larger sample, and the researchers hope to gain insight into how habits are formed.

By funding replication NWO wants to contribute to increasing the transparency of research and the quality of how results are reported. The funding instrument aims at cornerstone research that in the past formed the basis for follow-up research or have assumed an important place in education, policy-making or the public debate.

Sanne gave a lecture about the science of temptation and sticky habits to secondary school pupils who visited UvA for a day on the 5th of March 2020. The aim of the outreach event is to offer insight into what it is like to do research and study at the faculty of Social and Behavioral Sciences, UvA.

As part of a unique multidisciplinary research team, the Habit Lab is involved with one of the UMH projects, focussing on active and healthy aging. Under supervision of Prof. Richard Ridderinkhof (Dept. of Psychology – Developmental and Brain & Cognition), dr. Harm Krugers (SILS-CNS), Prof. Jaap Murre (Dept. of Psychology – Brain & Cognition) and dr. Sanne de Wit (Dept. Clinical Psychology, Habit Lab), Lotte Brinkhof will dedicate her PhD research to improving our understanding of the factors that affect healthy aging and resilience to stressful perturbations. The central part of this project concerns a network analysis, with the aim to find out which (and how) factors influence healthy aging and resilience to cope with (stressful) disruptions. These insights will then be used to develop and test personalized (preventive) interventions, specifically aimed at improving flexibility of behaviour and habit formation. As previous research has shown that people rely more and more on their habits as they age, it is expected that such interventions will be especially helpful in the elderly to promote the development of automatisms and thereby facilitate the achievement of goals. In addition, we will conduct translational studies (in rodents) to look at the direct influence of stressful perturbations on cognitive flexibility and habit formation during aging. This will help to understand and define the circumstances (and limitations) for optimal application of the interventions to stimulate habit formation. The ultimate goal: promoting healthy aging (in urban settings).

The newly founded Centre for Urban Mental Health  (UMH) aims to unravel the complexities behind mental health in urban environments and develop new intervention strategies. Research is aimed at understanding why some groups or individuals thrive in an urban setting, whereas others are vulnerable, get stuck and develop mental problems.

Tim obtained a KNAW Van der Gaag Grant to prof. John O’Doherty’s Human Reward and Decision-Making Lab at Caltech, California, USA. During his visit, he will analyze fMRI data that will be collected in the coming months, investigating the neural mechanisms underlying rapid habit formation using implementation intentions.

At the beginning of 2020, Tim was interviewed by the UvA-news about why people so often fail to attain to their New Year’s resolutions. Find the interview, which includes some practical tips for making and breaking habits, here: https://bit.ly/2ucpPpQ

On 23 January, Tim presented at the ROCKS meeting, Erasmus School of Social and Behavioral Sciences in Rotterdam. He mainly talked about several studies from his PhD thesis, titled ‘Addiction: a striatal roller-coaster: on the neural and associative-learning mechanisms underlying gambling and alcohol use disorder.

At the infamous NVP (December 19-21), Egmond aan Zee, Tim presented a poster on his recent work showing that taxing working-memory load leads to inflexible habitual responding. During a run on the beach, he also spotted a young seal that was drifted ashore! Lotte presented a poster on a study that was led by irene into routine formation (and implementation intentions) to promote medication adherence in healthy aging, in which lab and real-life measures of cognitive functioning and habit learning were combined. Last but not least, Irene presented a poster on the neural dynamics supporting habit acquisition and adjustment as investigated with a novel habit paradigm combined with EEG measurement.

On the 5th of December, Irene presented the first results of our study on the role of routine formation in the promotion of medication adherence in healthy aging to a large number of the older adults that participated in the study. Whereas this sneak preview was for a limited audience, once the final results are published they will of course be announced here!
