Sensation - lowest level - whereby physical features of the environment are converted into electrochemical signals that are sent to the brain for processing. Perception - later steps - whereby the initial sensory signals are used to represent object and events so that they can be identi ed, stored in memory, and used in thought and action. Perception: a process by which some form of physical energy is transformed into a psychological experience. Physical energy (external world) > psychological experience (internal) (1)distal stimuli -> (2)proximal stimuli -> (3)proximal stimuli converted to neural signals which are sent to the brain -> (4)signal processing in the brain. Distal stimulus: out there in the distance . Proximal stimuli: light/what comes into contact with sensory apparatus. Long history - rst psychology laboratory was a perception lab. Part of our attempt to understand our experience of the world - what we perceive is not always true to what is happening in the world.
