Figure 2: Model of meditation effects to promote optimal aging. The constant practice of attentional family meditation develops the metacognitive self-regulatory capacity of the mind. This consists in the voluntary control of attentional focus and keeping the attention in the present experience, without self-referential thinking and mind wandering. This metacognitive ability can modulate cognitive, emotional, behavioral, and autonomic output. The question is: Can these skills promote a healthy aging? ANS: autonomic nervous system, HPA: hypothalamic-pituitary-adrenal axis.
