Critcher, C. R., & Dunning, D. (2015). Self-affirmations provide a broader perspective on self-threat. Personality and Social Psychology Bulletin, 41(1), 3–18.

Across three experiments, self-affirmations may reduce defensiveness by widening the working self-concept so that a threatened attribute appears less all-defining — not just by adding more net self-worth.

Self-affirmation activates brain systems associated with self-related processing and reward and is reinforced by future orientation. Social Cognitive and Affective Neuroscience, 11(4), 621–629.

An fMRI study found reflecting on future-oriented core values during affirmation was associated with greater activation in self-referential (medial PFC, posterior cingulate) and reward (ventral striatum) regions, and this activity predicted later reductions in sedentary behavior.

Third-person self-talk facilitates emotion regulation without engaging cognitive control: Converging evidence from ERP and fMRI. Scientific Reports, 7, 4519.

Using third-person rather than first-person self-talk was associated with reduced neural markers of emotional reactivity (ERP and fMRI) without increasing cognitive control demands, suggesting it may be a relatively effortless emotion-regulation strategy.

Orvell, A., Ayduk, Ö., Moser, J. S., Gelman, S. A., & Kross, E. (2019). Linguistic shifts: A relatively effortless route to emotion regulation? Current Directions in Psychological Science, 28(6), 567–573.

Lally, P., Wardle, J., & Gardner, B. (2011). Experiences of habit formation: A qualitative study. Psychology, Health & Medicine, 16(4), 484–489.

Qualitative interviews suggest new health behaviors felt cognitively effortful at first but became easier as automaticity developed; performance was often disrupted when routine contextual cues were absent (e.g., weekends).

Verplanken, B., & Wood, W. (2006). Interventions to break and create consumer habits. Journal of Public Policy & Marketing, 25(1), 90–103.

The authors argue that interventions targeting beliefs and intentions are unlikely to disrupt established habits; disrupting contextual cues — especially during natural life transitions — may be more effective for change.

Neal, D. T., Wood, W., & Quinn, J. M. (2006). Habits — a repeat performance. Current Directions in Psychological Science, 15(4), 198–202.

Experience-sampling work suggests a substantial portion of everyday behavior involves habitual repetition, with actions initiated automatically by contextual cues rather than conscious deliberation.

Aarts, H., & Dijksterhuis, A. (2000). Habits as knowledge structures: Automaticity in goal-directed behavior. Journal of Personality and Social Psychology, 78(1), 53–63.

Three experiments demonstrated habitual responses may be triggered automatically when a relevant goal is activated, supporting the view that habits are stored as goal-action associations rather than mere frequency-based responses.

Combined PET and fMRI imaging found peak emotional responses to music were associated with dopamine release in the nucleus accumbens, while anticipation of those moments engaged the caudate — indicating music recruits the brain's reward circuitry in anatomically dissociable ways.

Koelsch, S. (2014). Brain correlates of music-evoked emotions. Nature Reviews Neuroscience, 15(3), 170–180.

A review of neuroimaging evidence found music-evoked emotions modulate activity across limbic and paralimbic structures (amygdala, hippocampus, nucleus accumbens, hypothalamus, orbitofrontal cortex), indicating broad engagement of emotion-processing networks.

Chanda, M. L., & Levitin, D. J. (2013). The neurochemistry of music. Trends in Cognitive Sciences, 17(4), 179–193.

A feature review suggests music may engage neurochemical systems involved in reward and motivation (dopamine, opioids), stress regulation (cortisol), immune function (serotonin), and social bonding (oxytocin), with the authors noting many findings remain preliminary.
