Document Summary
Major dimensions of motivation (clearly reflect darwinian processes): survival thirst, hunger, elimination, temperature regulation, pain and escape behaviour, fear and avoidance. Avoidance of events that may injure or kill you or your kin eg/ don"t fulfill hunger, you will die; eg/ don"t avoid extreme cold, you will die and not reproduce natural selection. Suicide seemingly is an exception, however there are mechanisms that may show that this is an adaptive mechanism: reproduction courtship, sexual behaviour, pregnancy and nursing, nurturance of offspring favoring kin. Emerges at puberty; innate (doesn"t need to emerge at birth) Choosing not to reproduce seems like an exception; there is an evolutionary logic that may cause this (eg/ birth control = evolutionary lag) We often forget that we are affected by this as much as other animals: competition threat and aggression, territoriality and dominance. Humans are high quality, heavy investment, low numbers, k selected mammals; yet humans can still face challenges. Anger and other emotions threat gestures.
