Motor performance may be improved by kinesthetic imagery, specific action verb production, and mental calculation

Motor performance may be improved by kinesthetic imagery, specific action verb production, and mental calculation.

Neuroreport. 2011 Nov 25;

Authors: Rabahi T, Fargier P, Rifai-Sarraj A, Clouzeau C, Massarelli R

Abstract. Several results in the literature show that motor imagery, language production, mental calculation, and motor execution share the same or closely related brain motor cortical areas. The present study aimed at investigating the possible influence of specific action verb (AV) pronunciation and mental calculus upon motor performance compared with kinesthetic imagery (KI). Participants, novice in mental imagery, performed a vertical jump after a cognitive task (AV, silent AV, mental subtraction, meaningless verb, and KI). The results show that specific lower limbs AV, mental calculation, and KI improved the vertical jump in male, but not in female participants.

Effects of mindfulness on psychological health: a review of empirical studies

Effects of mindfulness on psychological health: a review of empirical studies.

Clin Psychol Rev. 2011 Aug;31(6):1041-56

Authors: Keng SL, Smoski MJ, Robins CJ

Abstract. Within the past few decades, there has been a surge of interest in the investigation of mindfulness as a psychological construct and as a form of clinical intervention. This article reviews the empirical literature on the effects of mindfulness on psychological health. We begin with a discussion of the construct of mindfulness, differences between Buddhist and Western psychological conceptualizations of mindfulness, and how mindfulness has been integrated into Western medicine and psychology, before reviewing three areas of empirical research: cross-sectional, correlational research on the associations between mindfulness and various indicators of psychological health; intervention research on the effects of mindfulness-oriented interventions on psychological health; and laboratory-based, experimental research on the immediate effects of mindfulness inductions on emotional and behavioral functioning. We conclude that mindfulness brings about various positive psychological effects, including increased subjective well-being, reduced psychological symptoms and emotional reactivity, and improved behavioral regulation. The review ends with a discussion on mechanisms of change of mindfulness interventions and suggested directions for future research.

Improving spatial abilities through mindfulness: effects on the mental rotation task

Improving spatial abilities through mindfulness: effects on the mental rotation task.

Conscious Cogn. 2011 Sep;20(3):801-6

Authors: Geng L, Zhang L, Zhang D

Abstract. In this study, we demonstrate a previously unknown finding that mindful learning can improve an individual's spatial cognition without regard to gender differences. Thirty-two volunteers participated in the experiment. Baselines for spatial ability were first measured for the reaction time on the mental rotation task. Next, the participants were randomly assigned to either a mindful or mindless learning condition. After learning, the mental rotation task showed that those in the mindful learning condition responded faster than those in the mindless learning condition. This study provides promising evidence for applying mindful learning to education.

Meditation experience is associated with differences in default mode network activity and connectivity

Meditation experience is associated with differences in default mode network activity and connectivity.

Proc Natl Acad Sci USA. 2011 Nov 23;

Authors: Brewer JA, Worhunsky PD, Gray JR, Tang YY, Weber J, Kober H

Abstract. Many philosophical and contemplative traditions teach that "living in the moment" increases happiness. However, the default mode of humans appears to be that of mind-wandering, which correlates with unhappiness, and with activation in a network of brain areas associated with self-referential processing. We investigated brain activity in experienced meditators and matched meditation-naive controls as they performed several different meditations (Concentration, Loving-Kindness, Choiceless Awareness). We found that the main nodes of the default-mode network (medial prefrontal and posterior cingulate cortices) were relatively deactivated in experienced meditators across all meditation types. Furthermore, functional connectivity analysis revealed stronger coupling in experienced meditators between the posterior cingulate, dorsal anterior cingulate, and dorsolateral prefrontal cortices (regions previously implicated in self-monitoring and cognitive control), both at baseline and during meditation. Our findings demonstrate differences in the default-mode network that are consistent with decreased mind-wandering. As such, these provide a unique understanding of possible neural mechanisms of meditation.

‘Brainlink’ lets you remotely control toy robots and other gadgets

BirdBrain Technologies, a spin-off of Carnegie Mellon University has developed a device called Brainlink that allows users to remotely control robots and other gadgets (including TVs, cable boxes, and DVD players) with an Android-based smartphone. This is achieved through a small triangular controller that you attach to the gadget, with a Bluetooth range of 30 feet.

Apple and Google working on wearable stuff

Via Kurzweil AI

The New York Times Bits reports that Apple and Google have recently started working on projects that will become wearable computers, based on the smartphone, which is becoming the hub for our information sharing and gathering.

In Google’s secret Google X labs, researchers are working on peripherals that - when attached to your clothing or body — would communicate information back to an Android smartphone.

At Apple, one idea being discussed is a curved-glass iPod that would wrap around the wrist; people could communicate with the device using Siri, the company’s artificial intelligence software.

 

MIT to launch free online interactive learning labs in 2012

MIT announced today online learning initiative called MITx that will offer a portfolio of free selected MIT courses starting in Spring 2012 through an online interactive learning platform, with  online laboratories.

MIT expects that MITx will eventually host a virtual community of millions of learners around the world.
