Evolutionizing grief: viewing photographs of the deceased predicts misattribution of ambiguous stimuli by the...

We propose a cognitive-evolutionary model of grief where the function of grief is to reunite a person with an absent partner where this is possible, and where it is not, to disengage and reorientate the individual from the lost agent. The present study investigates the potential factors that affect reunion-promoting symptoms by focusing on the misattribution of external stimuli to the deceased by the bereaved--which we term 'false recognitions'. We propose three factors that relate to false recognitions: First, we propose that strong attachment to the deceased predisposes one to false recognitions; second, we predict that viewing photographs of the deceased (that were taken when the individual was alive) perpetuates false recognitions; and third, we propose that time elapsing since the death diminishes the frequency of false recognitions. In a survey of 164 recently bereaved (<25 months) pet owners in the U.S. and U.K., predictions concerning the association of the predictor and outcome variables were confirmed. The strongest predictor was the frequency of viewing photographic images of the deceased, a pattern consonant with our premise that, being evolutionarily novel, realistic photographs are treated as reliable cues that the agent remains a viable relationship partner. This research demonstrates the potential of evolutionary theory to inform mainstream bereavement research.
