Of guns and snakes: testing a modern threat superiority effect

Area of Science:

• Cognitive Psychology
• Evolutionary Psychology
• Neuroscience

Background:

• Evolutionary-based theories propose an innate module for detecting ancient threats.
• Alternative theories emphasize stimulus relevance over evolutionary threat ontology.
• Research is needed on attentional capture by modern, urban environmental threats.

Purpose of the Study:

• To investigate attentional capture by modern threats (weapons).
• To compare the attentional capture of modern versus ancient threats.
• To evaluate the relevance-based versus evolutionary-based explanation of threat detection.

Main Methods:

• Experiment 1: Assessed attentional capture using weapon vs. non-threatening cues.
• Experiment 2: Directly compared attentional capture by modern (weapons) and ancient (snakes) threats.
• Utilized a cue-target paradigm measuring reaction times.

Main Results:

• Weapons captured attention more effectively than non-threatening stimuli (Experiment 1).
• Participants responded faster to targets cued by modern threats compared to ancient threats (Experiment 2).
• Modern threats demonstrated superior attentional capture over ancient threats.

Conclusions:

• Findings support a relevance-based explanation for threat detection over an evolutionary-based one.
• Modern, contextually relevant threats may have a stronger impact on attention than evolutionarily ancient ones.
• Attention to threats is modulated by current environmental relevance rather than solely by innate predispositions.
