This review article aims to close this gap. Emotional tearing occurs during negative events (e.g., injuries) and positive events (e.g., achievements). Episodes of tearing appear to be united by tearers' subjective imputation of negative or positive value to certain internal or external phenomena. Knowing the degree to which objects, organisms, events, and states of affairs enhance or diminish one's prospects—the value of things—is a pressing matter for humans and other organisms. Value information is produced for internal consumption, to be used by behavior-regulating mechanisms in the focal individual. But some evaluations are made available, in addition, to other people, through tearing and other forms of verbal and non-verbal communication. Tearing may function as an implicit plea for receivers (the tear targets) to minimize the costs imposed on the tearer by nature, by third-parties, or by the tear targets themselves—common when the tearer has lower formidability or wherewithal than tear targets do. In addition, tearing may exhort tear targets to infer and register which things the tearer values, positively or negatively. Here, we characterize tears, describe the game-theoretic logic of bargaining from a position of weakness, outline the computational systems that regulate the production of and responses to emotional tears, and review findings about emotional tearing that are relevant to the signaling hypothesis.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"46 1","pages":"Article 106652"},"PeriodicalIF":3.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143152151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They must build systems with sufficient resources to solve the most complex problems the systems are expected to solve, but the systems will only need to solve such problems intermittently, resulting in inefficient use of expensive computational resources. This dilemma is commonly resolved with timesharing, networking, multitasking, and other technologies that enable computational resources to be shared with multiple users. The human brain, which evolved to acquire, store, and process information to make beneficial decisions in situations that were periodically complex, is likewise energetically expensive to build and maintain yet plausibly has idle capacity much of the time. We propose that humans evolved to use advantages in information or computational resources to provide computational services to others via a language-based “network” in exchange for payments of various sorts that helped subsidize the energetic costs of the brain. Specifically, we argue that with the Pleistocene transition of <em>Homo</em> to a niche in open habitats with a more meat-based diet, four major selection pressures for knowledge specialists began to act on the human lineage: (1) the need to resolve conflicts and maintain cooperation in larger multilevel societies, which lead to the rise of knowledge-based leaders as decision-making and conflict resolution specialists who were “paid” with increased mating success or resources; (2) the need for greater defense against zoonotic pathogens, which lead to the rise of shamans as medical knowledge specialists, who were “paid” with increased mating success or resources; (3) the greater complexity of mothering with shorter interbirth intervals and longer periods of juvenile dependency, which led to mothers as both decision-making and medical specialists, who were “paid” with increased inclusive fitness; and (4) the need to make more efficient use of an increasingly large and energetically expensive brain.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"46 1","pages":"Article 106651"},"PeriodicalIF":3.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143152153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PAT argues that during a critical period in early childhood, exposure to harsh and/or unpredictable conditions leads individuals to accelerate their pubertal maturation and engage in more mating effort alongside less parental (and potentially somatic) investment (and vice versa in response to benign or predictable cues.) A large body of literature has found small, but significant, empirical effects in support of these patterns. However, a separate body of research has increasingly revealed a number of significant challenges to the underlying assumptions of PAT. The goal of my paper was to therefore review PAT’s assumptions and any challenges to those assumptions. My review shows that all of PAT’s underlying assumptions have at least modest challenges to their validity, with the majority of those assumptions facing more severe challenges to their validity. I therefore suggest that future research on PAT should focus on addressing these potential challenges to the theory so as to offer a stronger theoretical framework with which to explain current empirical data about human life histories.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"46 1","pages":"Article 106657"},"PeriodicalIF":3.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143152208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
