Mindfulness and time perception – a cognitive study

Title: The effect of mindfulness meditation on time perception
Summary: Research based on the hypothesis that because mindfulness meditation focuses on living in the moment, practitioners’ perception of time would be changed compared to a control group. In a within-subject design experiment, participants carried out temporal bisection tasks. Results indicated that the perception of time duration of the experimental group was altered via attentional processes.

Title: Mindfulness: Towards A Critical Relational Perspective
Summary: This research acknowledges the increasing role of mindfulness in the west; enabling people to engage with new approaches to cope with issues connected to subjective wellbeing such as stress, depression and anxiety. It also discusses the appropriation of ‘mindfulness’ by psychology and the potential for conflict between its role in traditional and modern westernised meditation movements. A social critique, exposing the failure (and thus the potential opportunity) of psychology to integrate mindfulness as a personal and social practice.

Title: Loving-kindness Meditation for Posttraumatic Stress Disorder: A Pilot Study
Summary: A trial of loving kindness meditation was undertaken with veterans suffering from posttraumatic stress disorder (PTSD). Participants were given 12 weeks training in loving-kindness meditation and measured for PTSD, depression, self-compassion, and mindfulness at different stages. The effects of this pilot demonstrated a range of benefits for participants from the meditation and concluded that the practice was both “safe” and “acceptable”. A pilot study but really strong participant attendance (74% involved in 9 to 12 classes) and fascinating results:
- self-compassion increased with large effect
- mindfulness increased with medium to large effect
- PSTD symptoms subject to a large effect at 3-month follow-up (d = -0.89)
- depression subject to a medium effect at 3 months

Title: Neural correlates of attentional expertise in long-term meditation practitioners
Summary: With the use of fMRI it was found that people with an average of 19.000 hours of meditation experience had greater activation of brain regions associated with sustained attention than novice meditators. However it appears that experienced meditators with an average of 44,000 hours meditation had less activation of the same regions (inverted u-shaped curve distribution). When compared to novices, experienced meditators appear to have less brain activation in regions related to discursive thoughts but greater activation in response inhibition regions.

Title: Effects of Mindful-attention and Compassion Meditation Training on Amygdala Response to Emotional Stimuli in an Ordinary, Non-meditative State
Summary: There is a long standing association between the amygdala and emotional processing. Previous research has indicated that in a meditative state amygdala response to emotional stimuli could be reduced. However this investigation points to the possibility that the effect of meditation training on emotional processing may exert an influence beyond the meditative-state. Participants were given training in either Mindful Attention Training (MAT) or Cognitively-Based Compassion Training (CBCT).

Title: Regulation of the Neural Circuitry of Emotion by Compassion Meditation: Effects of Meditative Expertise
Summary: Functional magnetic resonance imaging (fMRI) investigation of the insula and anterior cingulate cortices in empathic response during loving-kindness, compassionate meditation. The contrast between rest and meditation states indicated increased activation in amygdala, right temporo-parietal junction (TPJ), and right posterior superior temporal sulcus (pSTS). The findings when taken in their entirety suggests the cultivation of positive emotional states through meditation creates changes to the activation of circuitries linked to empathy and theory of mind in response to emotional stimuli.
