though there are various challenges that come with habituation. some infants have preferences for some stimuli based on its static or dynamic properties. infant dishabituation also is not perceived at a direct measure for mental processes as well. in previous theories of habituation, an infant's dishabituation was though to represent their own realization of the remembered stimulus of stimuli. for example: if infants would be dishabitutated to a certain color item to a new item, we would know that they remembered the color and compared the two colors for differences. also another challenge that comes with habituation is the dichotomy of novelty vs familiar stimuli. if an infant preferred a novel still, this meant the infant observed the new spatial relation of the object, but not the object itself. if an infant preferred familiarity, the infant would notice the pattern of the stimuli, instead of the actual new stimuli.
