MACQUEEN Biological Psychology ASSESSMENT 4

The Stroop Effect And Visual Perception

Overview

Write a 2-part assessment that discusses your experience with the Stroop Effect and concepts related to visual perception. This assessment should be a minimum of 4 pages long.

One of the central hypotheses in psychology is the relationship between stimulus and response. Sight and language are two human abilities relevant to the hypothesis of stimulus and response. Your understanding of these two abilities will help you build up a concept of the neural basis of human behaviors interacting with the world.

Context 
Recent technologies employed in the study of the brain regions regulating speech are helping scientists better understand the neural basis of human behaviors interacting with the world. For example, MRI imaging studies are revealing other areas within the brain that may also play a role in language and reading. Another example is that both Broca’s and Wernicke’s areas are fundamental to speech ability, but the specific mechanism of how each plays into oral language is still unclear. This is still a new area that challenges psychologists, neurologists, and speech therapists. 
Humans use different parts of their brain to discriminate objects from people. In fact, we may have specialized neurons for recognizing faces. This relates to the main theme of this assessment: vision and visual perception. Many questions about human vision are unanswered. For example, different areas of the brain respond differently to visual recognition tasks, but how and why these areas cooperate to process visual information remains unclear. Another example: The visual cortex contains several layers, the functional roles of which are the subject of intense investigation. Questions include, “Why might the brain specialize to the point where a single neuron is dedicated to the recognition of a specific object or person?” and “What factors or cues do you think would influence how these neurons specialize and what they ultimately respond to?”

Questions To Consider

To deepen your understanding, you are encouraged to consider the questions below and discuss them with a fellow learner, a work associate, an interested friend, or a member of the business community.

•    Do you think, with the differences in the processing of sensory input, all of us experience the world (that is, colors and smells) differently? Is it possible that the perception of sensory input is different for every person? If this is the case, then how can we know if there is a problem with final integration?

•    How does the brain process what we see in the world? Resources

Assessment Instructions 
This assessment has two parts, Part A and Part B. Please complete this assessment in one document. You are required to use headings that stand alone and that are not incorporated into the content of the answers. Required headings have been provided for Part A, but you will need to use the questions from Part B as the stand-alone headings. 
Part A 
The famous “Stroop Effect” is named after J. Ridley Stroop, who discovered this strange phenomenon in the 1930s. For this task, words are printed in various colors. It is easy to name the printed colors of the words if the words are not color related or if each word is the name of the color in which it is printed; however, the task is very difficult when the words are color names that conflict with their printed color, for example, RED printed in blue ink. The discordant information (what the words say and the color of the print) produces interference in the brain. There are two hypotheses that may explain the Stroop effect:

1.Speed of Processing Hypothesis: the interference occurs because words are read faster than colors are named.

2.Selective Attention Hypothesis: the interference occurs because naming colors requires more attention than reading 
words.

The anterior cingulate is hypothesized to play a role in this task. If you wish, you can research images from MRI scans of what happens in the brain during a Stroop…
