Sitting and silent meditation as a strategy to study emotion regulation

Emotion regulation is the capacity to control the way in which people attend, perceive, process and react to emotional information. Practitioners of sitting and silent meditation develop a greater control of their mental processes, culminating in regulatory abilities that lead to well-being and emotional balance. In this paper we reviewed evidence from recent studies on neurophysiology and cognitive psychology on emotion regulation-focusing on negative emotions-and meditation in order to discuss their intertwining. This critical review showed that controlling attention and fostering a relaxation state are the main mechanisms for the interaction between emotion regulation and meditation. Importantly, it is suggested that the effects of meditation on emotion regulation should be conceptualized separately as those taking effect during the practice and those occurring as an outcome of such practice. Finally, it is highlighted that meditation should be conceived as a particular type of emotion regulation strategy, and that further studies comparing these strategies more directly are warranted.

Six weeks of meditation training influences response bias in a discrimination task with emotional distractors

Introduction: Focused attention meditation is the voluntary focusing of attention on a chosen object in a sustained fashion, whose objective is to develop attentional and emotional regulatory skills./objective: We investigated the effect of a six-week focused attention meditation training on a discrimination task with emotional distractors by comparing participants' discriminability and bias before and after training. Method: College students were randomly assigned to either focused meditation (N=35), progressive relaxation (N=37), or control groups (N=28). 120 neutral and 120 emotional - negative and arousing ­ pictures (9º x 12º), flanked by two peripheral bars (0.3º x 0.3º), equidistant from the centre of the picture (9º), were equally and randomly distributed and displayed among three blocks, one with low attentional (LA) and two with high attentional demand (HA). Participants indicated if bars were parallel or not by pressing one of two buttons. In LA and HA conditions, respectively, bars differed with 90º and 6º in half of the trials. Trials started with a fixation cross (1500ms) followed by the pictures and bars (200ms). Next, a chessboard remained on the screen until a response was given or for 2000ms. Results: Mixed-design ANOVAs showed no discriminability difference across groups (meditation=26; relaxation=24; control=24) pre-post training; only task difficulty affected discriminability [F(1,68) = 739.8, p < .001; LA > HA]. Response bias was affected by difficulty [F(1,68) = 81.2, p < .001; LA < HA], and testing session [F(1,68) = 23.1, p < .001; pre > post]. Additionally, there was a significant difficulty × session × group interaction [F(2,68) = 4.02, p = .02]: meditation (M = .58, SE =.36) and relaxation (M = .65, SE =.36) presented a reduction in response bias relative to control (M = .69, SE =.37), but only after training in the HA condition (p < 0.05). Conclusion: The reduction in response bias suggests that meditation and relaxation can affect decision making in a difficult perceptual discrimination task. Meditation showed the highest bias reduction, consistent with previous results linking meditation to attention and monitoring processes.
