What is perception?
Perception is the process by which the brain selects, organizes, and interprets information from our senses.
Distinguish between sensation and perception.
Sensation is the detection and transmission of sensory information, while perception is the brain's interpretation and understanding of this information.

Study Notes
Perception
Perception is the process by which the brain selects, organizes, and interprets information from our senses. It is the means by which we understand and make sense of the world around us. Perception is a complex process that involves not only the physical sensory information we receive but also our cognitive processes, emotions, and expectations.
Sensation and Perception
Sensation is the initial step in the perceptual process, where our sensory receptors detect and transmit information about the physical world. Perception, on the other hand, is the process by which the brain interprets and makes sense of these sensory inputs.
The Senses
Humans have five primary senses: sight (vision), hearing (audition), smell (olfaction), taste (gustation), and touch (somatosensation). Additionally, we have other senses, such as balance (vestibular sense), body position and movement (proprioception), pain (nociception), and temperature (thermoception).
Influences on Perception
Perception is not a passive process. It is influenced by a variety of factors, including attention, motivation, expectations, and cultural and embodied training.
Attention
Attention plays a significant role in determining what is sensed versus what is perceived. When we focus our attention on certain stimuli, we increase the likelihood of perceiving them, while other stimuli may become less noticeable due to inattentional blindness.
Motivation and Expectations
Motivation and expectations can also affect our perception. For example, if we are expecting a certain sound or smell, we may be more likely to perceive it even if it is present at a low level.
Cultural and Embodied Training
Perception is influenced by our cultural background and embodied training. For example, individuals from different cultures may have different perceptual responses to the same stimuli due to their cultural training and experiences.
Perception in Performance
Perception plays a crucial role in performance arts, where performers use their perceptual skills to direct their attention, remain present and aware, and make decisions based on multiple sources of information.
Theories and Research
Research on perception has evolved over time, with early studies focused on basic physiological processes and later investigations exploring how the mind interprets and organizes these perceptions. Modern research also examines how injury, conditions, and substances might affect perception.
The Perceptual Process
The perceptual process involves several stages, including transduction, selective processing, organization, and interpretation.
Transduction
Transduction is the process by which sensory receptors convert energy from the physical world into action potentials that can be interpreted by the brain.
Selective Processing
Selective processing involves the brain's ability to select and prioritize certain sensory information based on attention and motivation.
Organization and Interpretation
The final stages of the perceptual process involve organizing and interpreting the selected sensory information to make sense of the world around us.
Types of Perception
There are several types of perception, including visual perception, scent perception, touch perception, sound perception, and taste perception. Some of these types of perception are further divided into subcategories, such as person perception, social perception, and selective perception.
Potential Pitfalls of Perception
The perception process is not always smooth. Disorders that affect perception, such as Alice in Wonderland Syndrome, can interfere with our ability to interpret and respond to the environment.
In conclusion, perception is a complex and dynamic process that involves the interaction of sensory information, cognitive processes, emotions, and expectations. It is a process that is continually shaped by our experiences and cultural backgrounds. Understanding perception is crucial for navigating the world around us and for developing effective strategies for communication and interaction.
