This is a tumblelog, kinda like a blog but with short-form, mixed-media posts with stuff I like. Scroll down a bit to start reading, or a bit more to read more about me.

New published research from psychologists at the universities of Kent and Witten/Herdecke has shown that mindfulness meditation has the ability to temporarily alter practitioners’ perceptions of time – a finding that has wider implications for the use of mindfulness both as an everyday practice, and in clinical treatments and interventions.
Led by Dr Robin Kramer from Kent’s School of Psychology, the research team hypothesised that, given mindfulness’ emphasis on moment-to-moment awareness, mindfulness meditation would slow down time and produce the feeling that short periods of time lasted longer.
To test this hypothesis, they used a temporal bisection task, which allows researchers to measure where each individual subjectively splits a period of time in half. Participants’ responses to this task were collected twice, once before and then again after a listening task. By separating people into two groups, participants listened for ten minutes to either an audiobook or a meditation exercise designed to focus their attention on the movement of breath in the body. The results showed that the control group (audiobook) didn’t change in their responses after the listening task compared with before. However, meditation led to a relative overestimation of durations i.e. time periods felt longer than they had before.
According to a new study, mindfulness meditation has the ability to temporarily alter practitioners’ perceptions of time.
The reasons for this have been interpreted by Dr Kramer and team as the result of attentional changes, producing either improved attentional resources that allow increased attention to the processing of time, or a shift to internally-oriented attention that would have the same effect.
Dr Kramer said: ‘Our findings represent some of the first to demonstrate how mindfulness meditation can alter the perception of time. Given the increasing popularity of mindfulness in everyday practice, its relationship with time perception may provide an important step in our understanding of this pervasive, ancient practice in our modern world.’
Dr Kramer also explained that the benefits of mindfulness and mindfulness-based therapies in a variety of domains are now being identified. These include decreases in rumination, improvements in cognitive flexibility, working memory capacity and sustained attention, and reductions in reactivity, anxiety and depressive symptoms. Mindfulness-based treatments also appear to provide broad antidepressant and antianxiety effects, as well as decreases in general psychological distress. As such, these interventions have been applied with a variety of patients, including those suffering from fibromyalgia, psoriasis, cancer, binge eating and chronic pain.
Dr Dinkar Sharma, Senior Lecturer in Psychology at Kent, commented: ‘Demonstrating that mindfulness has an effect on time perception is important because it opens up the opportunity that mindfulness could be used to alter psychological disorders that are associated with a range of distortions in the perception of time – such as disorders of memory, emotion and addiction.’
Dr Ulrich Weger, of Witten/Herdecke’s Department of Psychology and Psychotherapy, concluded by stating that ‘the impact of a brief mindfulness exercise on elementary processes such as time perception is remarkable’.
Venus, photographed in the UV by Venus Express, 18-19 February 2007. As well as the clouds, there are some camera artefacts which appear to move with the planet’s “rotation” (Venus rotates extremely slowly, and the apparent rotation here must be caused by the changing position of the spacecraft).
For those playing at home, the raw data for Venus Express is in the Atmospheres node of the PDS, which is why it’s taken so long for me to post a decent Venus gif (who knew there were pictures in the Atmospheres node…?), and also from the ESA’s website via FTP.
(Blog note: This is the 300th gif posted to this Tumblr, a postiversary of sorts, not counting a lone text post and a couple of “doubles”, where the same sequence is shown twice with slightly different editing. When I started this blog, I wasn’t sure I’d make it to 50 posts, and 200 was my most optimistic goal. And there’s still a bit of life in it yet: Cassini’s archive is enormous and rewards multiple trawls through it; the astronaut photos are often harder to work with gif-wise because of their unsteady hands, but there’s certainly some interesting material in there. I think there’s enough to keep the daily updates going till sometime in August.
Thanks to those who’ve been following along; and for those late to the party, there’s plenty in the blog’s archives now, organised by tag (e.g., Voyager, Io). Almost all major solar system bodies are represented, if there’s a decent time-lapse animation of them (though there’s a couple more asteroids still to come!).)
It’s cool when your job is making you a better person.
