Chapter 4- Sensation and Perception * Sensation vs. Perception * Sensation- Basic processes by which sensory receptors and the nervous system: Receive and represent stimulus energies from environment‚ and entails basic psychological experiences. * Bottom-Up Processing- Sensory detection and encoding; construction of whole from parts. * This includes Lines‚ shapes‚ angels‚ colors‚ items/events that grab our attention * Perception- Interpretation and integration

them. Marketing stimuli have important sensory qualities. We rely on colors‚ odors‚ sounds‚ tastes‚ and textures (the “feel” of products) when forming evaluations of them. Each of these sensations is discussed and placed into proper context of marketing usage and attention attraction. How do our sensory receptors pick up sensations? The answer is exposure. Exposure is the degree to which people notice a stimulus that is within range of their sensory receptors. A stimulus must be presented at

Human Sensory Systems Objectives · Describe how sensory receptors communicate to the central nervous system. · Describe receptors that detect temperature‚ pain‚ touch and pressure‚ muscle length and tension‚ and blood pressure. · Describe the nature of vision in terms of its stimulus on the function of rod and cone cells. Introduction The function of the brain is to convey messages to different parts of the body. Messages are conveyed from a nerve cell to another nerve cell‚ muscle cell

3.1 How does sensation travel through the central nervous system‚ and why are some sensations ignored? Sensation is the activation of receptors located in the eyes‚ ears‚ skin‚ nasal cavities‚ and tongue. Sensory receptors are specialized forms of neurons that are activated by different stimuli such as light and sound. 3.2 What is light‚ and how does it travel through the various parts of the eye? The natural agent that stimulates sight and makes things visible. Light rays enter the eye through the

Chapter 2: Perception Difference between perception and sensation our own “spin” on things is the perception that we get from it. Sensation is the immediate response of our sensory reactions to things Perception is the process by which these sensations are selected‚ organized‚ and interpreted. Perception is what we take away from our raw sensations Example is the cola and the pepsi‚ using only senses‚ we cannot tell the difference between them but if we are to add in perception of the beand

that some "force feedback" joysticks and video game steering wheels provide is another form of haptic feedback. ("What Is "haptic Feedback"?") Haptic technologies known as haptic feedback is technologies that allow users to feel a response from a system‚ not just see or hear a response; optimally‚ can replicate the sensation of feeling an object in the real life to create a virtual tactile experience. (Anderson‚ Greg‚ David L. Ferro‚ and Robert Hilton) Haptic feedback is a signal that you’re electronics

2. Information a. Our sensory systems evolved to pick up information (not just stimulation) b. In general‚ information is provided by change c. Change can occur over time‚ or over space 3. Transduction - The process of converting stimulus energy into nerve impulses - Generally‚ stimulus energy causes a change in a receptor cell’s electrical potential (voltage) - If change is enough‚ it will trigger “nerve impulses” 4. Transmission - For perception to occur‚ sensory organs (containing receptors)

Memory Process Memory is a person’s ability to form‚ store‚ retain‚ and retrieve information. The process of memory consists of three steps‚ which are encoding‚ storing‚ and retrieving. Among those steps there are stages of memory known as sensory memory‚ short-term memory‚ and long-term memory. Of the three steps in the memory process‚ encoding is the most critical of them all. Encoding Encoding is the process used to transform information so it can be stored (AllPsych‚ 2011). Also the

Lab report on Sensory Threshold In this lab the purpose is to test the sensory threshold of a human body. To say it in terms that are easier to understand‚ we are testing how accurate certain points are on a body with response to touch. We are using three points on the body‚ the forearm‚ palm‚ and index finger. With these three points we will be testing to see how sensitive each point on the body is by measuring the distance of which we can feel one or two points. The part of the brain that allows
