Question description

Habituation is generally defined as a decrease in response to a stimulus after repeated exposure.  For example, the first time you walk into your friend's room you notice the smell of dirty gym clothes, and you gag from the terrible odor.  After walking into your friend's room over and over you begin to not even notice the smell of the dirty clothes, and subsequently you no longer gag.  In this example the odor from the dirty clothes is the stimulus and the gagging is the response.  Please read the article by Rankin and colleagues (2009) and answer the following questions:

Come up with your own example of habituation in your daily life and identify the stimulus and response.  Choose any three of the characteristics of habituation described in the article (link posted bellow) and describe how those characteristics can (or could) be seen in the example of habituation that you've come up with.


Example of a Good Post:

Q1: Read the article "Seven Sins of Memory." Choose two of the "sins" to discuss and explain how these particular memory flaws have affected your life.  Please use the article and Chapter 7 of the textbook to support your thoughts. 

In his article, “The Seven Sins of Memory,” Daniel L. Schacter outlines the seven major “ sins” that attribute to human memory being fallible at times.  Two of these sins that I felt most certainly applied to me are “absent mindedness” and “ blocking.”  Schacter explains that the sin of absent mindedness occurs when we place insufficient attention on a stimulus at the time of encoding or retrieval or the attended information is processed superficially (Schacter, 1999).  For example, if someone is in a big hurry to get out the door for work, they may forget where they put their cell phone down, as their focus was primarily on getting themselves out the door.  I think absent mindedness is something that happens to me on a daily basis.  For example, if I’m having a conversation with someone, but have something on my mind, like studying for an upcoming exam, I will have a full conversation with that person, but remember little to nothing when the conversation is over.  On a few occasions, I’ve asked the same person the same questions I did in our previous conversation without realizing it, simply because I wasn’t paying attention to the information when it was being encoded in my mind, as Schacter would put it.  I think the concept of absent mindedness would also explain behaviors I occasionally find myself doing, such as forgetting where I put my car keys or leaving perishable food out of the refrigerator.

 The other sin I find myself guilty of from time to time is what Schater refers to as blocking. Blocking occurs when a deeply encoded fact or event, which has not been lost over time, is temporarily unavailable and can not be retrieved (Schacter, 1999).  As Schater explains in his article, one of the most common examples of this phenomenon is the “tip of the tongue” experience.  For example, if a friend asks you the name of a famous actor in a movie and you know that you know the answer, but can’t recall it at the moment even though you feel like at any moment you’ll be able to blurt it out, then you’ve experienced blocking.  I think that the concept of blocking coincides much with what chapter 7 of the text terms as an “intrusion error.”  An intrusion error occurs when other knowledge intrudes into the remembered event (Reisberg, 2010).  For example, once a friend asked me what kind of car was parked across the street from my house.  For whatever reason I couldn’t think of the name even though I had seen them a hundred times (blocking) and for some reason I wanted to say it was a vintage Mustang (intrusion error), even though I knew it wasn’t.  Overall I found Schacter’s article to be very insightful as to the potential pitfalls in human memory.
