How Threat Shapes Attention and Memory in the Himba, a Remote People of Namibia

Threatening stimuli capture our attention more rapidly than benign stimuli, and threatening experiences lead to longer lasting and more vivid episodic memories. The common interpretation of these findings is that humans share an evolved fear response that enables prioritized processing of threats, providing a survival advantage. This response is assumed to be universal; however, these findings have been documented almost entirely in WEIRD (western, educated, industrialized, rich, and democratic) populations. Here, we address this gap by examining threat detection and fear memories in a remote African culture, the Himba. We found that threats captured attention more rapidly than benign stimuli, and that fear memories, despite differing in content, were shaped by threat in a similar manner to that reported in WEIRD populations.
