It has been four years since the previous edition of Evolutionary Psychology: The New Science of the Mind. In that time period, there has been an explosion of conceptual and empirical work in the field. For this edition, over 1,000 new publications were surveyed and almost 400 new articles were included in the new edition. The book retains its organizational structure and provides a much-needed and massive updating from the previous edition. · Chapter 2 Updates : Expanded discussion of new empirical methods, notably cross-cultural methods, physiological methods, brain imaging methods (fMRI), and molecular genetic methods · Chapter 3 Updates : New and expanded discussion of social and cultural aspects of food; the emotion of "disgust" as an adaptation for disease avoidance; the potential role of fire and cooking in human evolution; evolved navigation theory and the descent illusion (very cool!); humans as a "hostile force of nature" · Chapter 4 Updates : New or expanded sections on studies from the "speed dating" experimental method; new empirical findings on the age at which hunting skills peak in hunter-gatherer societies (mid- to late-30s); behavioral evidence from "hits" to personal ads; context-specificity of desire for "kindness" in a mate; new section on "mate copying" research; behavioral findings on actual marriages that correspond to stated mate preferences; deception in online dating services; lesbian sexual orientation. · Chapter 5 Updates : Includes new eye tracking studies; women''s misperceptions about how thin they think men desire in a mate; cross-cultural work on waist-to-hip ratio, including preferences of congenitally blind men; importance of BMI (body mass index); new work on cues to ovulation; expanded discussion of new theories and findings on male homosexual orientation; effects of men''s preferences on behavioral phenomena such as visual attention, vocalization, tips, and engagement rings · Chapter 6 Updates: effects of attractiveness on receptivity to sexual offers; desire for sexual variety from two separate massive studies of more than four dozen cultures; hooking up and ''friends with benefits''; perception of short-term mating from visual cues such as masculine features; context effects of family environment and ''mate value'' on mating strategies. · Chapter 7 Updates: New research oneffects of paternity uncertainty on men''s parenting and investment; effects of mother''s resources on maternal investment patterns; effects of co-wife status on sex of offspring; trade-offs between parenting effort and mating effort; mother-child conflict and sibling relatedness; parent-offspring conflict over mating (especially ''daughter guarding''). · Chapter 8 Updates: New research on phenotypic resemblance as a cue to kinship; effect of genetic relatedness on life-or-death altruism toward kin (new studies); effect of mothers and grandmothers on fertility of daughters and granddaughters; effects of maternal grandmothers, who invest more than paternal grandmothers; additional tests of the "grandmother hypothesis" of menopause, with additional theoretical development of the hypothesis; "alloparenting;" sibling conflict over resources such as inheritances.

· Chapter 9 Updates: New studies on memory for cheaters in social exchange; expanded discussion and empirical work on ''indirect reciprocity'' and ''costly signaling'' as explanations for acts of altruism; effects of altruism on social status and reputation; preferential social selection of altruists; opposite-sex friendships and the special problems they pose; same-sex friendship and sex differences in their nature. · Chapter 10 Updates: New box on the ''recalibration theory of anger,'' and attendant empirical work on it; new experiments on links between status confrontations and aggression; social ostracism as a female tactic of same-sex aggression; aggression from those diagnosed with ''pathological jealousy''; adaptations to assess fighting ability; expanded discussion of hypotheses and empirical tests of warfare adaptations, including bioarcheological evidence. · Chapter 11 Updates: New research on men''s ''sexual over-perception bias''; individual differences among men in the sexual over-perception bias; deception on the mating market; effect of status on perceived sexual harassment; individual differences in rape-proclivity; a re-reevaluation of the empirical status of the ''mate deprivation hypothesis'' of sexual coercion; new section on rape in marriage; women''s defenses against sexual aggression; new research on sexual jealousy; individual difference predictors of mate retention tactics; risk factors for partner violence. · Chapter 12 Updates: New section on ''prestige signaling, reputation, and leadership''; risk taking among men as a function of status of observers; selective attention, through eye-tracking procedures, to socially dominant men; socially dominant individuals use dual strategies of prosocial and coercive behavior; effect of height on leadership; hormonal work linking testosterone and dominance, dependent on other hormones such as estodiol; self-esteem as a ''mate value tracking device.'' Chapter 13 Updates: New research on Rationality versus ''adaptive rationality'' debate in cognitive psychology; evaluation of competing theories for the evolution of language; expanded discussion of theories and research on the evolution of morality; expanded discussion of evolutionary developmental psychology, with an emphasis on extended childhood, conditional adaptations, and gene-environment interactions throughout development; ''theory of mind'' research, and individual differences in skill at reading others'' minds; expanded discussion of new research on individual differences, including ''reactive heritability'' account of extraversion and psychopathic strategies; expanded discussion of cultural and ecological inputs into evolved adaptations; biases in cultural information transmission, including ''conformity bias'' and ''prestige bias''; evolution of the arts and literature.
