Public Perceptions of Memory Failures in Infant ‘Hot Car’ Deaths

Abstract

Caregivers can forget young children in the back of the car, thereby resulting in the tragic circumstance of infant death. The current exploratory study examined whether the public (N = 171) believes a memory explanation when the defendant caregiver relationship to the child is varied and when expert witness testimony is and is not provided regarding the processes by which these memory failures can occur. Adult participants believed that a memory failure played a role when the defendant caregiver was the grandfather as opposed to when the caregiver was the father. Expert witness testimony did not impact this belief. Other memory-related variables impacted perceptions of defendant guilt when defendant guilt was measured continuously but not dichotomously. Numerous non-memory related outcome variables were also studied. Defendant relationship and expert witness testimony impacted different memory-related and non-memory related outcome variables. Results are discussed in terms of age-related forgetting and collective vulnerability versus prospective memory failures. Implications regarding the legal system are considered.
