Sensory Processing & Perception
Experiment one
I came to believe that the closer that the object get, the greater the lens curvature. The larger the eye shape, the further the object must be to focus. The larger the eye, the greater the lens shape must be. I hypothesized that near sightedness develops when a person has a smaller eye shape and far sightedness develops when a person has a larger eye shape, like a football.
Experiment two
The experiment I am going to write about is experiment two, which is titled Sensory Receptors in the Skin. The hypothesis that our group came up with was that the distribution amongst sensory receptor must influence one’s perception. This experiment will test the hypothesis by having one person be a volunteer to be tested. One person from the group will test that person, by using a gauge. When using this gauge one pushes down on the volunteer’s skin until they say what feels like one point. Once we see where they say to stop, we record it in our lab manuals. I predicted that the volunteer will say that the gauge feels like it’s one point when the points aren’t even close, resulting in a long distance read. The hypothesis was supported by the results, because there was a long distance that we recorded for the majority of the measurements. For the most part, the measurements were either far or medium, and that is what I predicted in the first place, and it was in the hypothesis. The evidence that my conclusion was correct was that we measured eleven out of the seventeen measurements were far or medium, which shows that the hypothesis was supported. Chart below.

Essay on sensory perceptions

Sensory Perceptions Human observers have fair accuracy within certain restricted domains. An example is a comparison of a flying ant and termites. The correct classification of each can repeatedly and accurately be made by many different observers with minimal training, thus making unaided vision and an accurate detector of termites. Despite elevation of human detectors by specialists in this field as the ultimate standard, the domains of accuracy, precision and resolution of the human senses, and…

Temporal Processing Analysis

Temporal Processing relies on spatial-temporal patterns of all sensory and motor action potentials. When our sensory neurons are stimulated, processing of this stimuli occurs in our brain. We are able to discriminate various stimuli mostly upon the spatial patterns of activation, that is, by which afferent fibers are active. For example, the discrimination of a pitch of two high-frequency tones (that activate different critical bands on the basilar membrane) also activate different afferent nerve…

Key Terms Chapter 3 Sensation: the process through which the sense pick up visual, auditory and other sensory stimuli and transmit them to the brain. Perception: the process by which the brain activity organizes and interprets sensory information. Absolute threshold: the minimum amount of sensory stimulation that can be detected 50% of the time. Difference threshold: a measure of the smallest increase or decrease in a physical stimulation that is required to produce a difference in sensation that…

Sensory Processing Disorder

Sensory Processing Disorder (SPD), also referred to as Sensory Integration Disorder, was discovered by Jean Ayres in the 1960s. There are many children and adults suffering from Sensory Processing Disorder and receiving therapy for their symptoms, however the debate on whether SPD is a stand-alone developmental disorder, or actually a sign of other underlying problems has led to much controversy among patients, doctors, and therapists.

Adolescent/Adult Sensory Profile

Introduction: The Adolescent/Adult Sensory Profile (AASP) is a standardized assessment that measures the sensory processing needs of adolescents to adults from ages 11 and up (Dunn, 2014). The AASP is a 60-item questionnaire gathers information about the adolescent’s or adult’s responsiveness to various sensory stimuli and then identifies the processing deficits within the sensory systems that may disable the individual from participating in daily activities. Brown & Dunn (2002) state…
