Classical conditioning pairs visual cues with food to trigger reflexive physiological and behavioral reactions. When the reflex occurs using the cue without or without food, then the target has been successfully conditioned. This is tested by using the cue to subconsciously trigger feeding during usually non-feeding times.
Fear conditioning involves matching visual cues with threats and non-threats so that the cue can be used to induce stress even in otherwise non-threatening situations. Visual harassment signals that the odd events are intentionally directed at the target and not the occasional bizarreness of ordinary life. Recently the color tan as part of a color scheme early in the week to signal non-threats but at the end of the week it was used in combination with animal prints to signal threats.
Habituation occurs when the target becomes used to the cue and stops responding with a startle reflex. To re-habituate the startle reflex, a new but similar cue is used. For this reason the colors change about every month and instead of a single color an entire color scheme is used.
Silent swarms: using visual cues. Silent swarms are used to condition and build up stress in the weeks prior to an entrapment attempt. If a target reports being subjected to this frequently then they are likely the target of a behavior conditioning efforts.
