Social Resources

The Connection section drew on an unusually wide range of disciplines: evolutionary anthropology, social neuroscience, sociology, behavioural genomics, attachment research, clinical psychology, cultural anthropology, and practitioner literature, so I needed to take a slightly different approach to the other resource pages in Part 1.

A note on the field’s particular epistemic landscape: connection research is less mature than some of the other domains covered in the Manual. The strongest findings (epidemiology of social isolation, behavioural genomics of loneliness, longitudinal predictors of wellbeing) sit alongside contested areas (specific evolutionary psychology claims, polyvagal theory’s mechanistic specifics, social media causation in adolescent mental health) where the evidence is genuinely mixed.

 

Foundational Researchers and Their Major Works

This section lists the major academic figures whose research anchors the Connection section, each appearing once with their key works and brief framing.

  • John Bowlby and Mary Ainsworth — Attachment Theory: The foundational architects of attachment theory. Bowlby’s three-volume Attachment and Loss (1969, 1973, 1980, Basic Books) articulated attachment as an evolved behavioural system. Ainsworth’s Patterns of Attachment (1978, with Blehar, Waters & Wall, Lawrence Erlbaum Associates) established the Strange Situation methodology and the three original attachment categories. Mary Main’s subsequent work at UC Berkeley extended the framework to adults via the Adult Attachment Interview and identified the fourth (disorganised) category.
  • David Buss — Evolutionary Psychology of Mating: The Evolution of Desire: Strategies of Human Mating (revised 2016, Basic Books, originally 1994) is the foundational cross-cultural research on mate preferences. When Men Behave Badly: The Hidden Roots of Sexual Deception, Harassment, and Assault (2021, Little, Brown Spark) is the synthesis on sexual conflict. The descriptive cross-cultural findings are more robust than some of the evolutionary explanations; engage with both.
  • John Cacioppo — Loneliness as Biological Condition: Loneliness: Human Nature and the Need for Social Connection (2008, with William Patrick, W.W. Norton). The foundational synthesis of three decades of research establishing loneliness as a biological signal with measurable cellular consequences. Cacioppo died in 2018; his collaborator Louise Hawkley continues the programme.
  • Susan Cain — Introversion (Synthesist): Quiet: The Power of Introverts in a World That Can’t Stop Talking (2012, Crown). Useful entry point to introversion research for general audiences. Cain is a journalist rather than a primary researcher; some specific claims simplify the underlying science. Good as introduction; reach for the primary research (Eysenck, Brian Little, Jonathan Cheek) for substance.
  • Sue Carter and Larry Young — Pair Bonding Neurobiology: Sue Carter’s Neuroendocrine perspectives on social attachment and love (1998, Psychoneuroendocrinology 23(8): 779-818) and Larry Young’s The neurobiology of pair bonding (2004, with Wang, Nature Neuroscience 7(10): 1048-1054) are the foundational papers establishing the prairie vole as the major model organism for pair bonding research. Young’s lab at Emory has been the major site for subsequent work.
  • Jonathan Cheek — Subtypes of Introversion: The STAR model (Social, Thinking, Anxious, Restrained) articulated in Cheek, Brown & Grimes (2014, unpublished research manuscript, Wellesley College). More popularly developed than formally established; useful as descriptive taxonomy.
  • James Coan — Social Baseline Theory: Lending a hand: social regulation of the neural response to threat (2006, with Schaefer & Davidson, Psychological Science 17(12): 1032-1039) is the foundational hand-holding fMRI study. Social Baseline Theory: the role of social proximity in emotion and economy of action (2011, with Beckes, Social and Personality Psychology Compass 5(12): 976-988) is the theoretical articulation. Coan’s group at the University of Virginia has produced the bulk of subsequent research.
  • Steve Cole — Behavioural Genomics of Social Isolation: Social regulation of gene expression in human leukocytes (2007, with Hawkley, Arevalo, Sung, Rose & Cacioppo, Genome Biology 8(9): R189) established the CTRA gene expression pattern. The conserved transcriptional response to adversity (2019, Current Opinion in Behavioral Sciences 28: 31-37) is the major review. Cole’s lab at UCLA has produced the most rigorous molecular evidence we have for the biology of chronic loneliness.
  • Robin Dunbar — Social Brain Hypothesis: Neocortex size as a constraint on group size in primates (1992, Journal of Human Evolution 22(6): 469-493) is the foundational paper. The anatomy of friendship (2018, Trends in Cognitive Sciences 22(1): 32-51) is the major review. Friends: Understanding the Power of Our Most Important Relationships (2021, Little, Brown) is the accessible synthesis. How Many Friends Does One Person Need? Dunbar’s Number and Other Evolutionary Quirks (2010, Harvard University Press) is the earlier popular synthesis.
  • Naomi Eisenberger — Social Pain Neuroscience: Does rejection hurt? An fMRI study of social exclusion (2003, with Lieberman & Williams, Science 302(5643): 290-292) is the foundational Cyberball paper. The pain of social disconnection: examining the shared neural underpinnings of physical and social pain (2012, Nature Reviews Neuroscience 13(6): 421-434) is the major review.
  • Hans Eysenck — Foundational Personality Psychology: The Biological Basis of Personality (1967, Charles C. Thomas). The foundational articulation of the cortical arousal model of introversion-extroversion that anchors personality neuroscience.
  • Eli Finkel — Modern Marriage Research: The All-or-Nothing Marriage: How the Best Marriages Work (2017, Dutton). The articulation of how historical changes in marriage expectations have produced both higher ceilings and lower floors for relationship satisfaction. The suffocation of marriage: climbing Mount Maslow without enough oxygen (2014, with Hui, Carswell & Larson, Psychological Inquiry 25(1): 1-41) is the academic foundation.
  • Helen Fisher — Neurobiology of Romantic Love: Why We Love: The Nature and Chemistry of Romantic Love (2004, Holt Paperbacks). The foundational synthesis distinguishing the three brain systems of lust, romantic attraction, and attachment as separate neural systems. Anatomy of Love: A Natural History of Mating, Marriage, and Why We Stray (revised 2016, W.W. Norton). The cross-cultural and evolutionary treatment. Fisher’s website at helenfisher.com and the Kinsey Institute resources at theanatomyoflove.com are accessible companions.
  • Shelly Gable — Active Constructive Responding: What do you do when things go right? The intrapersonal and interpersonal benefits of sharing positive events (2004, with Reis, Impett & Asher, Journal of Personality and Social Psychology 87(2): 228-245). The foundational research on capitalisation and ACR.
  • John Gottman — Relationship Research: The Seven Principles for Making Marriage Work (2015, with Nan Silver, Harmony) is the accessible synthesis. What Predicts Divorce? The Relationship Between Marital Processes and Marital Outcomes (1994, Lawrence Erlbaum Associates) is the academic foundation. What predicts change in marital interaction over time? (1999, with Levenson, Family Process 38(2): 143-158) is the longitudinal trajectory paper. The Gottman Institute at gottman.com is the major practitioner resource.
  • Robert Greene — Strategic Power Analysis: The 48 Laws of Power (1998, Viking), Mastery (2012, Viking), and The Laws of Human Nature (2018, Viking) form the major trilogy. Greene is a synthesist drawing patterns from historical case studies, not a primary researcher. Mastery maps cleanly onto the empirical literature on expert performance and prestige-based status; Laws of Human Nature is the most useful of the three for relationship-building purposes.
  • Jonathan Haidt — Social Psychology and Adolescent Mental Health: The Righteous Mind: Why Good People Are Divided by Politics and Religion (2012, Pantheon). The articulation of the hive switch and moral foundations theory. The Anxious Generation: How the Great Rewiring of Childhood Is Causing an Epidemic of Mental Illness (2024, Penguin Press).

  • Joy Hirsch — fNIRS Social Neuroscience: Interpersonal agreement and disagreement during face-to-face dialogue: an fNIRS investigation (2021, Frontiers in Human Neuroscience 14: 606397). Plus Separable processes for live “in-person” and live “Zoom-like” faces (2023, Imaging Neuroscience 1: 1-17). Hirsch’s group at Yale has produced the major body of work on the dorsal-vs-ventral stream divergence between in-person and video-mediated interaction.
