SENSORY PROCESS AND PERCEPTION Introduction to Sensation and Perception Although intimately related, sensation and perception play two complimentary but different roles in how we interpret our world. Sensation refers to the process of sensing our environment through touch, taste, sight, sound, and smell. This information is sent to our brains in raw form where perception comes into play. Perception is the way we interpret these sensations and therefore make sense of everything around us. SENSATION Sensation is defined as the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
The brain and spinal cord comprise the __central__ nervous system. The neurons that link the brain and spinal cord to the body’s sense receptors, muscles, and glands form the _peripheral_ nervous system. 5. The ___EEG____ is a recording of the electrical activity of the whole brain. 6.
Additionally he identified that different regions of the brain interact or work together to enable a process. Thus leading to his findings that loss of speech can arise from damage to the front half of the brain Schiller, 1979, cited in Toates, (2010). Geschwind (1972), cited in Toates, (2010), also found that brain regions interact to enable the performance and understanding of speech. His evidence came from an experiment that entailed a participant listening to a sentence and then repeating it. Geschwind concluded that brain interactions were necessary to carry out the instructions.
A given state is the result of thecombination of an internal representation and a physiology. So what happens isthat an event comes in through our sensory input channels which are: Visual Including the sights we see or the way someone looks at us; Auditory Including sounds, the words we hear and the way that people say those words tous (unless you specifically want variety in form); Kinaesthetic Or external feelings which include the touch of someone or something, thepressure, and texture; Olfactory Which is smell;
Learning Activity Unit 2 Study Guide: Senses and Perception Senses 1. List the five senses and the area of the brain where each is processed. a. Smell- receptor neurons in the frontal lobe b. Taste- brain stem c. Touch- parietal lobe d. Sight- occipital lobe e. Hearing- temporal lobe 2. Explain the purpose of the sensory organs and how they send messages to the brain. • Sensory organs function as receptors and receive the stimuli, then it sends nerve impulses to the related effectors.
Introduction: Vision is one of five major senses of human beings. This sense works in the same fundamental way as any of the other senses. That is, a stimulus is intercepted by a receptor and whether it is a part of a sensory neuron which it activates directly, or it indirectly activates it through the release of chemicals such as acetylcholine. Vision is the detection of electromagnetic energy in the range of 380-750nm wavelength, also known as visible light. This detection is carried out by photoreceptors within the human eyes.
But they have discovered that there are various ways for memories to be formed. The brain itself shapes how we form memories. Memories dealing with fear, love , etc…are called emotional memories. The brain has pathways for processing information that allow us to have emotional reactions before we know to what we are reacting. Emotional feelings reveals when we become consciously alert that an emotion system of the brain is active.
How do we organise our visual sensations into perception? Sensation and perception a two terms that both relate to how one experiences and understands the environment they are in. Despite being related (and often confused), they have very different meanings. Sensation can be defined as the process in which information is taken from the outside world through our sensory organs into our brains. This occurs through the five different senses – touch, hearing, taste, smell and sight.
The first modality to be discussed is kinaesthetic, which represents our feeling system. People who are primarily kinaesthetic have a tendency to tune into other people’s emotions quickly, like to touch and experience things and rely on their “feelings” to assess situations. In terms of an induction this group of people may like words such as feel, warm, soft, smooth and touch. With eye accessing cues, these types of people tend to have eye movements down to the right and may have a softer, lower tone to their voice and breathe naturally from their abdomens. The second main modality is visual and these individual’s will have a tendency to visual daydreams and imagination, they will be good at imagining a picture or a scene in their mind.
The process through which we make sense of the world around us can be understood by studying two different key concepts known as Sensation and Perception (Baron, 2001). Sensation is about the initial contact between an organism and its psychical environment. In this process our nervous system and sensory receptors receive stimulus energy. These sensory
