Psychology on the Web
1. Select one topic of personal interest to you that was mentioned in this set of 
modules (for instance, cochlear implants, visual illusions, psi). Find one “serious” or 
scientifi c website and one “popular” or commercial website with information about 
the chosen topic. Compare the type, level, and reliability of the information that you 
fi nd on each site. Write a summary of your fi ndings.
2. Are there more gestalt laws of organization than the four we’ve considered (closure, 
proximity, similarity, and simplicity)? Find the answer to this question on the Internet 
and write a summary of any additional gestalt laws you fi nd.
We have noted the important distinction between 
sensation and perception, and we have examined the 
processes that underlie both of them. We’ve seen how external stimuli evoke sensory 
responses and how our diff erent senses process the information contained in those 
responses. We also have focused on the physical structure and internal workings of the 
individual senses, including vision, hearing, balance, smell, taste, and the skin senses, 
and we’ve explored how our brains organize and process sensory information to 
construct a consistent, integrated picture of the world around us. 
To complete our investigation of sensation and perception, let’s reconsider super-
recognizers like C. S., who are able to recognize faces years after they have met people, 
often only in passing. Using your knowledge of sensation and perception, answer these 
questions:
