The purpose of this experiment is to determine the response time for dominant and non-dominant hand for visual stimuli, and using only dominant hand to test auditory and tactile response. Also, to test involuntary the response time for the reflex of the knee from calculating the distance. Based on my group hypothesis, we said that visual stimulus dominant hand had a faster response time than non-dominant hand because the dominant hand is use more often thus repetition creates stronger connection. For only dominant we said that auditory response has the fastest reaction time because the auditory stimuli gets process faster compare to tactile and visual that has to travel longer to reach frontal lobe for response decision. For involuntary response,…

Detects how and when we detect the presence of a faint stimulus(“signal”) amid background stimulation(“noise”). Assumes that there is no single absolute threshold and that detection depends partly on a person’s experience, expectations, motivation, and level of fatigue.…
Weber’s Law refers to a noticeable deference, according to the text on page 186. “The stronger the initial stimulus, the greater a change must be for us to notice it.” I see this law being implemented into brands all the time. I like to shop online, it convenient and easy to do. I often receive emails for a particular brand about their upcoming sales events; most times I over like them because the percentage is not noticeable enough to grab my attention. Cole Haan is a brand that I like to order from often, whenever there is a great sale. Which is like every two months, however this is not fact but an opinion. When the Cole Haan brand has an extra 40% off sale, it is then I make my purchases. The 40% off includes on clearance items also, which…

To understand better how the brain processes visual information, an understanding of, and a clear differentiation between sensation and perception is required. Before stimuli can be perceived or interpreted, it must first be sensed through the sense. Therefore, sensation is the stimulation of sense organs (i.e., eyes, ears, nose, mouth, and skin) and involves the absorption of energy, such as light and sound waves through the sensory organs, (Weiten, 1998). Perception refers to psychological processes in which the immediate organization and interpretation of sensations are involved (Riegler & Riegler, 2008) and “involves organizing and translating sensory input into something meaningful,” (Weiten, 1998, p. 123).…
With experiment one I took a piece of sandpaper and rubbed my finger across it a couple of times. The texture was about a 5 on a scale from 1 to 7 being very course. I could feel the bumps on my fingertip as my finger went across the sandpaper which made me ignored about the sensation. It also felt as though my finger was still on the sandpaper after I had it off of it. After waiting two minutes I then re did the same experiment by rubbing the same finger across the sandpaper again. At this time my brain was saying the sensation was the same but my finger was use to the coarseness so it did not feel as bad this time. So I then rated the second time at a 3. Although this time when I released my finger the sensation stayed longer.…
Stimuli are classified by type (modalities) such as light, heat, sound, pressure and specific chemicals…
Sensation is described as the stimulus of the reactors that our brain receives whenever we utilize any of our five senses such as hearing, seeing, smelling, tasting, or touching. Sensory adaptation occurs when the "continued presence of that same stimulus results in a loss of sensitivity" (ref). In order for the brain to continue to experience the stimulus, "a stronger stimulus is needed in order to activate the reactors" (ref). To test the experience of sensory adaption, three experiments were conducted, involving touch and taste.…
Analyze your college or workplace using Weber's model of bureaucracy. What elements (efficiency, calculability, predictability, and control) of McDonaldization do you see? Do you wish life were less McDonaldized? Why or why not?…
Provide at least three reasons for believing in the accuracy or inaccuracy of sensory information.…
If fortunate enough, most people are able to sense the world around them through all five senses; sight, sound, smell, taste, and touch. The information from these senses is paired with thoughts and memories from each experience, which the brain uses to tell individuals how to perceive input from the outside world. The following information will cover reasons for believing in the accuracy of sensory information, the contributing factors to accurate sensory data, and the role of nature versus nurture with regard to the interpretation and evaluation of sensory data.…
