1. When learning about the Availability Heuristic I was thinking back to previous chapters on memory. Research found that when people were encouraged to recall pleasant events from their memory, pleasant events seemed more likely in their future, effecting the way they make decisions. In contrast if people were encouraged to recall unpleasant events they saw unpleasant things happening in their future. The belief bias, the confirmation bias, and the illusory correlation all emphasize top-down processing. When decision making we must take advantage of our memory, concepts, and previous knowledge. Although deductive reasoning uses established rules to draw conclusions, and decision making is much more difficult to distinguish if our conclusions are correct, both require thinking. Thinking requires us to go beyond information that we are given. Deductive Reasoning, Decision Making, and Problem Solving all take heuristics to help lead us to appropriate situations. 
2. I am still somewhat unclear on the anchoring and adjustment heuristic. It becomes more clear to me when I see the similarities to the availability heuristic. The highly available information is acting as the anchor. It makes sense to me that the anchor restricts the search for more relevant information in memory, so would an initial anchor be an example of when you form a stereotype when first meeting someone without knowing anything about them? 
3. Students are faced with decision making in all areas of their school work and in the real world. We do a lot of conditional reasoning tasks in class, but it is our job as teachers to make sure students are taught heuristics, or strategies to help them make decisions as they are faced with them in life. We need to make sure they know the misconceptions such as sample size, base rates, recency, and familiarity before making the decisions that they do. It is our job to show them the research to prove each heuristic,  just as the text is teaching us through demonstrations.

  1. I think that stereotyping can fall into several categories. One of which is the belief bias fallacy where we make beliefs on prior beliefs or general knowledge. The social cognition approach also talks about stereotypes created by our normal cognitive process relying on available heuristics. The book refers to the anchoring and adjustment heuristic as when "we make adjustments to that number" (pg. 429, 6th Edition). Whether "that number" means an actual number or another thing, I don't know. What I got out of it was that we need to "look at both sides of the coin" in analyzing potential decision making information.

  2. I thought it was interesting that you mentioned that encouraging people to recall positive information will allow them a more positive future. As a counselor, I was constantly talking with clients about things that were negative in their lives. In the future, I hope to incorporate positives into our conversations more. This will hopefully help them to move forward in a positive manner, even though the negative cannot be avoided. Like all of us, you also see how important learning decision making is for students. It seems like no matter whether or not we agree with the information in the text, we all think it is very important to actually learn some type of strategy for learn decision making skills.

  3. Maybe I'm wrong but I see the anchor as your background knowledge. It's recent and available information that you have collected based on your experiences. Once we have realized we are simply relying on our anchor, we need to make sure we look at the facts and then adjust our decision if it is different from the anchor (but I bet sometimes it could be the same so you don't need to adjust it). But, only change your anchor if the facts really persuade you to change your answer based on cold, hard facts. I could be completely off, but this is how I see it. Kind of like when we get new info, we check to see if it fits into another category and have to look at its features and the features that are already in our category and if it fits, put it in the category, and if it doesn't, create a new one. That is how I see the anchor. But, don't take my word...I'm not the expert on this!
