Further, this threat response is most efficient in response to short-term or predictable stressors (“threats”) but loses its efficiency for ambiguous or unpredictable threats. Despite research that suggests that threat induces psychological states associated with breakdown in cognitive control processes, no study has directly examined how predictability of threat impacts neurocognitive indicators of cognitive control processes. …
