PSYC304
Perception

Week 1
Forum

There are two parts to this assignment. The first part is an
introduction and the second part is related to the course.

Part 1. Introduction

This part of the assignment should be a minimum of 150 words
and requires completion for credit for the first forum.

You’ve probably experienced being required to do this in
prior classes. It’s an important element of any class because we enjoy knowing
who we are talking to. Where are you stationed or do you live? What are some of
your interests? What do you enjoy doing when you’re not in this class working
away learning about sensation and perception? What is one thing that you wonder
about perception? Please include three specific goals that you hope to attain
from this course.

(NOTE: Please don’t copy an idea from the course syllabus or
text–this question is about what you bring to the class before ever seeing
those materials).

Part 2. Processes in perception. This part of the forum
should be 150 words.

After watching the two videos below, discuss the role of
higher-level or “cognitive” processes in perception. Then describe a situation
in which you initially thought you saw or heard something, but then realized
that your initial perception was in error. What was the role of bottom-up and
top-down processing in this process of first having an incorrect perception and
then realizing what was actually there?

Support your belief and use specific examples. You may refer to your assigned Week 1
readings or draw on scholarly online resources. The latter must be academic in
nature (e.g. from the APUS online library) and not from pop culture and/or
commercial websites, blogs, opinion sites, etc.

Week 2
Forum

Upon viewing the video on the Anatomy and Physiology of
Hearing (the link can be found in the syllabus), describe the structure of the
ear, focusing on the role that each component plays in transmitting the
vibrations that enter the outer ear to the auditory receptors in the inner
ear. Then, discuss the basic difference
between determining the location of a sound source and determining the location
of the visual object. Lastly, discuss the differences a person may experience in
hearing when living in the city versus a rural environment. Support your belief
and use specific examples.

Week 3
Forum

Many people wear glasses to compensate for the fact that the
optical system of their eye does not focus a sharp image on the retinas. Once you have reviewed the videos below,
discuss at least three of the disorders of focusing. Be sure that you are discussing the complete
epigenetic origin which should include a discussion of the genetic/biological
origin and the environment influence related to these disorders of focusing.
Include in your discussion the impact of culture in the development of the
optical system at various stages of the lifespan. Support your belief and use
specific examples.

Week 4
Forum

First, watch the video below discussing the primary visual
cortex. Then discuss a minimum of two functional properties of visual cortical
cells. Include in your discussion how the human brain uses these properties in
perceiving objects in our everyday activities. In addition, discuss three
things (objects, situations, age etc.) that can impede the normal functioning
of these properties.

Support your answer and use specific examples. You may refer
to your assigned Week 3 readings in the syllabus or draw on scholarly online
resources. The latter must be academic in nature (e.g. from the APUS online
library) and not from pop culture and/or commercial websites, blogs, opinion
sites, etc.

Week 5
Forum

Color is all around us, but just how deeply integrated is
the phenomenon of color into our senses and neural pathways? Describe
trichromatic theory and opponent-process theory of color vision, including the
observations on which it is based and the physiological basis of each theory.
Lastly, watch the video on synaethesia below, and discuss what it means to say
that color is created by the nervous system. Explain what everyday life would
be like for an individual with the disorder, including its impact on
occupation, relationships, and leisure time. Be sure to include how the
disorder might affect the person’s behaviors and experiences in these settings.

Perception

Week 6
Forum

The idea behind selective adaptation is that when we view a
stimulus with a specific property, neurons tuned to that property fire, and if
viewing continues for long enough, these neurons adapt. Discuss how the
psychophysical procedure of selective adaptation has been used to demonstrate
the link between feature detectors and (a) the perception of orientation, and
(b) the perception of size. Be sure to include a discussion of your
understanding of the rationale behind selective adaptation experiments and how
we can draw conclusions about physiology from the results of such a
psychophysical procedure. Provide two examples for the class that support your
conclusions. For this week’s discussion, it is expected students will use their
readings and outside scholarly web sources to answer this question completely.

Week 7
Forum

This week we will examine the chemical sense of smell
(olfaction) and taste. This is a two-part
discussion question (part one pertaining to olfaction and part two pertaining
to taste) and both parts must be answered in order to receive full credit.
After viewing the material for this week as outlined in the syllabus, discuss
the components of the olfactory system: the olfactory receptors, the olfactory
sensory neurons, the olfactory bulb and the cortex. Then, discuss what kinds of
evidence support the idea that different people may have different taste
experiences. What mechanisms might be responsible for these differences?
Lastly, explain the role of culture in the development of smell and taste and
provide two examples of how culture could account for variation in perception.

Week 8
Forum

Learning to recognize; is this merely a human trait? After
watching the videos for this week as listed in the syllabus, discuss what it
means that our perceptional system has been shaped by the properties of the
environment and provide two examples to support your point. In addition, discuss
the strengths and limitations of human facial recognition and list some of the
problems that make facial recognition and/or object recognition difficult for
computers, but not for humans.
