Previous issue date: 2012-05-28 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Human cooperation is a hallmark of this species due to its wide extension to genetically unrelated
individuals and complex division of labor. It is considered an evolutionary puzzle, because the
theory of evolution by natural selection predicts that self-interested individuals tend to be selected.
Different theories have been proposed to explain the evolution of cooperation, which the most
important are kin selection and reciprocal altruism. Considering the evolutionary continuity
between species, humans and other primates have several common traits that help to promote
cooperation between individuals of these species. Two features, however, seem to be particularly
humans: inequality aversion and preferences in relation to others. Although human cooperation is
not necessarily related to morality, cooperative traits are the basis for moral tendencies. The
development of human morality is a combination of early prosocial tendencies, cooperative skills
displayed at different ages, social learning and cultural transmission of norms. The social stimulus
seems to be particularly important in promoting cooperative behavior in children and adults. In
order to study the influence of social stimuli, as verbal feedback, on children cooperation, a study
was conducted with children in a public goods game. 407 children from public schools in Natal /
RN, divided into 21 groups, between six and nine years, participated in eight rounds of this game.
After each round, seven groups received praise for larger donations, seven groups have been
criticized by smaller donations, and the other seven received no comment. Children cooperated
more when criticized, without significant differences between sexes, although young children have
cooperated more negative than older children. The results are likely related to the anticipation and
avoidance of punishment associated with the feedback (although this did not occur), and greater
sensitivity to the authority in younger children. Nevertheless, the cooperation decreased in all
groups until the last day of play. The results suggest an early sensitivity to moral punishment,
whose role in the maintenance of social relations must have been important in the evolution of
cooperation in humans / A coopera??o humana ? um tra?o distintivo da esp?cie, devido ? sua ampla extens?o ? n?o
aparentados e elaborada divis?o do trabalho. ? considerada um quebra-cabe?a evolucionista, tendo
em vista que a teoria da evolu??o por sele??o natural prev? que indiv?duos auto-interessados tendem
a ser selecionados. Diferentes teorias foram propostas para explicar a evolu??o da coopera??o,
sendo as mais importantes a sele??o de parentesco e o altru?smo rec?proco. Considerando a
continuidade evolutiva entre esp?cies, seres humanos e outros primatas possuem v?rios tra?os em
comum que ajudam a promover a coopera??o entre indiv?duos dessas esp?cies. Duas caracter?sticas,
no entanto, parecem ser particularmente humanos: a avers?o ? desigualdade e as prefer?ncias em
rela??o aos outros. Embora a coopera??o humana n?o necessariamente esteja relacionada ?
moralidade, tra?os cooperativos servem de base para tend?ncias morais. O desenvolvimento da
moralidade humana resulta da combina??o de tend?ncias pr?-sociais precoces, de habilidades
cooperativas exibidas em diferentes idades, de aprendizagem social e transmiss?o cultural de
normas. O est?mulo social parece ser particularmente importante na promo??o de comportamentos
cooperativos em crian?as e adultos. Tendo como objetivo estudar a influ?ncia do est?mulo social,
sob a foma de feedback verbal sobre a coopera??o infantil, foi realizado um estudo com crian?as em
um jogo de bens p?blicos. 407 crian?as de escolas p?blicas de Natal/RN, divididas em 21 grupos,
entre seis e nove anos, participaram de oito partidas desse jogo. Ao fim de cada partida, sete grupos
receberam elogios pelas doa??es maiores, sete grupos foram criticados pelas doa??es menores, e os
outros sete n?o receberam nenhum coment?rio. Crian?as cooperaram mais em situa??es de cr?tica,
sem diferen?as significativas entre sexo, embora crian?as mais jovens tenham cooperado mais em
feedback negativo do que as crian?as mais velhas. Os resultados provavelmente est?o relacionados ?
expectativa e ? esquiva de puni??o associada ao feedback (embora esta n?o ocorresse), e ? maior
sensibilidade ? autoridade em crian?as mais jovens. Apesar disso, a coopera??o diminuiu em todos
os grupos at? o ?ltimo dia de jogo. Os resultados apontam para uma sensibilidade precoce ? puni??o
moral, cujo papel na manuten??o das rela??es sociais deve ter sido importante na evolu??o da
coopera??o na esp?cie humana
