- Describe the process of perception as a series of steps, beginning with the environmental stimulus and culminating in the behavioral responses of perceiving, recognizing, and acting.
- Because the long axons of neurons look like electrical wires, and both neurons and electrical wires conduct electricity, it is tempting to equate the two. Compare and contrast the functioning of axons and electrical wires in terms of their structure and the nature of the electrical signals they conduct.
- What are the two answers (one “simple” and the other “profound”) to the question, “Why is our perception of colors and details worse in dim illumination than in bright illumination?”
- What is color constancy? Describe three factors that help achieve color constancy. What is brightness constancy? Describe the factors that are responsible for brightness constancy. Lastly, compare and contrast color constancy with brightness constancy.
- When you walk from outside, which is illuminated by sunlight, to inside, which is illuminated by “tungsten” illumination, your perception of colors remains fairly constant. But under some illuminations, such as street lights called “sodium vapor” lights that sometimes illuminate highways or parking lots, colors do seem to change. Why do you think color constancy would hold under some illuminations, but not others?
- What is sensory adaptation? How does it occur within the various senses? What function does sensory adaptation serve? Provide a relevant example that illustrates your point.
- What are the characteristics of the energy that we see as visible light? Provide an example illustrating how these characteristics are expressed when someone sees a rainbow. What types of things (situations and/or objects) can interfere with these characteristics?
- How does the eye transduce light energy into a neural message? What is the blind spot in the eye and how does it impact the transduction of light energy?
- How is visual information processed in the brain? What are some things (situations and/or objects) which can impede visual information being processed in the brain? Please include a relevant example to illustrate your answer.
- What theories contribute to our understanding of color vision?
infrastructures, expanded markets, access to technologies, free movement of labour and capital, investment, and political relations in form of integrations. These benefits have played a major role in the economic developments of developing countries. However, some countries argue against free trade claiming that it is a burden to developing countries and they object it. Some arguments against include exploitation of developing countries by industrialised, environmental pollution, unemployment of domestic workers, and underperformance of domestic industries thus affecting the country’s economic growth. Free trade has positively impacted to developing countries by stimulating their economic development goals such as millennium development goals thus it can be said to be realistic in the real world. Free trade was found to work out for countries such as Japan, South Korea, China, other East Asia countries, and most of the developed countries in the world. Trade liberalization led to development of these countries and to attainment of their current level of ‘developed countries’ in the world. The countries formed ‘free trade and economic partnership agreements that helped in negotiations of trade across borders was important in facilitating trade,’ technical support, services, environmental and social issues (Zeng, 2010 p. 651). The guidelines helped countries to carry out trade in a defined environment that prevented them from exploiting each other in terms of natural resources. As a result, the countries realised developments. This has also worked out for developing countries such as those in sub-Sahara Africa for example Egypt. Moreover, free trade agreements encourage foreign direct investments in developing countries increasing inward revenues to these countries. The increased revenues to these countries are channelled to development projects such infrastructures and improving social amenities to citizens. In addition, foreign direct investments create employment for domestic workers thus helping developing countries to lower their unemployment rates. This is one of the achievements that have contributed greatly to shifting of countries from>GET ANSWER
