Introduction: animals sense world differently than we do, cognitive processes, at least initially, are influenced by sensory input. In humans, specialized receptors that respond to fine touch are concentrated on areas such as the fingertips and face i. e. braille. Other systems that can detect electric and magnetic fields: sharks have electroreceptors that perceive natural electrical stimuli, homing pigeons can return home by sensing the earth"s magnetic field and other orientation cues. Sensory signals travel through the central nervous system and are recombined in a way that is meaningful to an animal. This connection between sensory input and the analysis of that input describes the relationship between sensation and perception. 5: perception: interpretation when sensory information processed, organized, filtered, stimulus filtering: separating and extracting meaningful info from environment, sign stimuli & releasers:
