Signals, a group of signals that are all presented to the same receiver across two or more sensory modalities. Him talking using two right now visuals and voice, using two sensory channels. Multicomponent is using one channel - multiple component all in the same sensory channel: ex. If a signal is multimodal it should be harder to fake. Three reasons for that: 1) increases honesty ex. A signal"s efficacy" improves the better it can be: top two as saliences. Be redundant, or be non-redundant: that is enhance one another, or act synergistically: ex. Bright coloured and sing to attract mates, in forest can"t see you but hear you reduance. Hears his good voice she is attracted to him, that same female can"t hear hum but sees him, cues are working reduntly: strengthen the response of another.
