Anger research among the Aka hunter-gatherers of the Central African Republic

 

The Aka, also known as the BiAka or Babenzele, are a group of so-called “pygmy” hunter-gathers in the Central African Republic with a population between 15 and 30 thousand (Bahuchet 1985).  The Aka have their own language (diaka) and culture including a strong preference for forest life, high mobility, ritualized elephant hunting and a trading relationship with the Ngandu farmer populations.  Their diet includes 63 different plant species, 20 insects including caterpillars which are a seasonal delicacy, honey from eight species of bees, and 28 different game animals.  The most common cause of death is infectious-parasites which account for half of all Aka deaths (Hewlett et al. 1986).  Malaria is also common.  The homicide rate of the Aka is very low for a foraging people (approximately .003%) though still higher than the United States (approximately .00005% in 2008).  There has never been a report of an Aka woman dying from male violence (Hewlett et al. 1986).


Aka culture is extremely egalitarian with band-wide sharing of food, predominate monogamy (though polygyny is accepted), incredibly high levels of paternal investment in children, and low levels of spousal violence.  The Aka have been called the “Best Dads in the World.”  Unlike other hunter-gatherers in the area, Aka practice family net hunting in which men, women and children participate.

The Aka field site near Bagandou was established by Barry Hewlett over thirty years ago and has been opened to collaborative anthropologists at Washington State University.


Ongoing projects include:
    1). The role of physical strength in anger among men and women.
    2). An investigation into the elements of status.
    3). A cross-cultural analysis of latent and explicit meanings of insults and their relation to cultural norms and values.
