Internal or external events have a signaling significance to an organism and subsequently affect learning and behavior. Sensory signals (sometimes referred to as “cues”) can be internally generated (i.e., through brain processes associated with perception, for example) or externally generated (through a visual cue from a food commercial). Food cues affect hunger and nutritional choices (Duszka et al., 2020).
