Effect of Resource Availability on Dyadic Fitness

PDF Version Also Available for Download.

Description

College students participating in dyads played a game designed as an analog of early hunters whose survival, as a dyad and ultimately individually, depend on rabbits they hunt. Dyadic fitness was defined as both participants being able to hunt and it was measured by the proportion of trials in a condition that both participants hunted. The effects of scarcity (alternating rich and poor conditions) on dyadic fitness were examined in two experiments. First experiment results did not show a difference in dyadic fitness as a function of the independent variable. The second experiment increased the number of hunting seasons and ... continued below

Description

College students participating in dyads played a game designed as an analog of early hunters whose survival, as a dyad and ultimately individually, depend on rabbits they hunt. Dyadic fitness was defined as both participants being able to hunt and it was measured by the proportion of trials in a condition that both participants hunted. The effects of scarcity (alternating rich and poor conditions) on dyadic fitness were examined in two experiments. First experiment results did not show a difference in dyadic fitness as a function of the independent variable. The second experiment increased the number of hunting seasons and also the discrepancy between scarcity in rich and poor seasons. Second experiment results show that dyads start fit in rich seasons and become increasingly fit in poor seasons. External variables could not be ruled out; therefore, additional experiments still need to be carried out to clarify results.
