Cognitive Effort — Cognitive effort is the mental work required to examine information, compare alternatives, solve problems, and make deliberate decisions. Familiar choices require less cognitive effort because the person already knows what to expect and how to respond. The mind can mistake this reduced effort for evidence that the familiar option is the better choice. — Neurological Process

Cognitive Effort — Cognitive effort is the mental work invested in understanding information or completing a task. Unfamiliar, complicated, or conflicting material generally requires more effort than familiar material. Effort reflects the demands of the activity and does not directly establish a person’s intelligence. — Cognitive Process
