Find the new questions and answers from the session here.
This page is devoted to class questions and my answers to them. Since very often, many people have the same questions, I think it is helpful to give our entire class access to all the questions that are asked. When you have class questions, check here and check the syllabus. If you find your answer, GREAT! If not, please do one of these four things:
If you email me your question and include your email address, I'll respond directly to you and post your questions on this board. If you email me and do not include your email address (or if you have no account of your own) I'll simply post the question and answer here.
If for some reason, you do NOT want me to post your question to the class (if it is of a personal nature or for any other reason) let me know, and I'll only respond to you.

I'm a strong believer in team effort, and one of the best ways to study would be with a friend from class. I'd suggest that each member of a study group should write a few "sample" questions for each lecture and then see if the other members of the group can answer them properly. For examples of the types of questions I write, see the exams page.
Some other places to look for sample questions are: our text's web page (look under the chapter you want to practice with and go to "sample essay questions"). Also, the author of our text has a nice web page for another text she wrote on lifespan development. Since both books have a lot of the same material in the early chapters, you could test yourself using the online quizzes provided on that text's web page, which can be found here.
From Fall 1999 Study Session:
Sing to the tune of supercalifragilisticexpiallydocious:
T-A-I, I-E-I, G-I ally docious
T-A-I, I-E-I, G-I ally docious
T-A-I, I-E-I, G-I ally docious
T-A-I, I-E-I, G-I ally docious
The letters are for: T-rust vs. Mistrust, A-utonomy vs. Shame and Doubt, I-nitiative vs. Guilt, I-ndustry vs. Inferiority, E-go Identity vs. Role Confusion, I-ntimacy vs. Isolation, G-enerativity vs. Stagnation, and I-ntegrity vs. Despair.
So, mitosis is normal cell division. We start with a diploid cell, and it replicates all the chromosomes and splits in two, so we end up with TWO cells, each of which are diploid at the end.
On the other hand, meiosis is cell division that creates gametes. So, we start with a diploid cell, and it replicates once and divides twice, so that we wind up with FOUR cells, each of which are haploid at the end. So, meiosis leaves us with FOUR gametes.
I hope this helps fill in your notes, let me know if you need more clarification!

As far as knowing the strengths and weaknesses, these can be personal judgements. I won't test you on the quality of your judgements, but I do want to know that you have some feelings about why theories are useful or not!
Think about the little "taco" we made in class - and where each layer was...

Remember in class that I said that we each need to come up with something that works for us when we have to learn a difficult concept. I'll try to frame the IV - DV distinction in a couple of different ways here, and then I'll put some sample experiments on the handouts page. If you are having trouble with this area, use the sample experiments to test yourself. I'll put the answers up on a separate handout.
Ok, first, think about a general experiment. The researcher wants to find out what happens when s/he manipulates some variable. THE VARIABLE S/HE MANIPULATES IS THE INDEPENDENT VARIABLE. What happens when the researcher manipulates the independent variable is that the dependent variable is somehow changed. Remember though, that the researcher can't actually change or manipulate the DV directly - so it is the dependent variable that is changed (not by the researcher) but by the independent variable.
So, when I say I'm interested in learning how using a web page affects the grades of students in a class, (think about this) I can't go to my students and say "OK, you guys make A's and I want you guys to make F's." If I did that, the only question I'd be answering is "will students earn the grades that their instructor tells them to?". Instead, I have to put some students in a class that uses a web page, and another group in another class, with the same teacher (and as much else the same as possible) that doesn't use a web page. Then, I can look to see what kinds of grades kids from each class get. So, now, before you go on to the next paragraph, try to identify the IV, the DV, the control group, and the experimental group.
IV = Use of web page (levels are web page present or absent). DV = grades of students. Control group = the group without the web page. Experimental group = the group with the web page.
If I want to know how age affects love of animals, I'd group my subjects by age, and then test to see how each age group likes animals. The IV would be age, the DV would be love of animals. In this case, I couldn't have a control group, because there is no way to pick a group that isn't exposed to the IV (age), but I can have several experimental groups - one of kids 0-2, one of 3-6, and so on.
Another hint, if you can re-phrase an experiment to fit this question, then you can ALMOST ALWAYS figure out the IV/DV.
How does ___1___ change ___2___?
IF you fit an experiment to fit this question, #1 will be your IV, and #2 will be your DV.
Don't forget to check the handouts page, I'll put up the other examples shortly - then, if any of you still need help, ask again, and I'll do my best to explain it in a different way.
Resistant attachment is characterized by a strong need for closeness during free play preiods of the strange situation. These children will not leave the side of their parents - they seem to be very "clingy" to the point of not being able to do anything on their own. When the parent leaves and returns, the child is angry that they were left, and will not respond well to the parent.
Disorganized / Disoriented kids tend to seem utterly confused. They don't really behave in a very characteristic way (so you can't say they will do the same thing every time in the strange situation). Sometimes they act dazed, sometimes they cling, and other times they act as if they don't recognize that the parent is in the room.
secondary circular reactions: the child finds certain objects in the world interesting, and so acts on them over and over in the same way to experience the interesting objects for as long as possible. So, a child may see a helium balloon floating on a string and pull the string over and over again to make the balloon bounce.
coordination of secondary reactions: the child has now learned to control objects in the world, and so can work to reach goals. So, a child may have learned how to bang a stick on the ground, so when s/he sees a xylophone, the child can bang a stick on the xylophone to make sounds.
tertiary circular reactions: the child has had enough experience with objects to notice that they don't always do the same thing. So, s/he is now actively interested in seeing "what happens if?". A child in this substage might drop a ball, then throw the ball, then hit the ball, then spin the ball to see what types of action the ball makes for each action the child makes.
Compare this with intermodal perception, where perception in both domains occurs at the same time. So, my daughter squooshes a leaf, and she knows that the crunchy sound and the leaf are connected, but she can see them and hear them at the same time.

The surprise paradigm works under a similar assumption. It is also called the habituation paradigm, and works by exposing a child to some stimulus until they seem bored (no longer look). You can then show them another stimulus, and if they show surprise or begin to look again, you know that they see this stimulus as different from the first.
The preference paradigm allows us to know what infants like. As in the Dunham et al. (1991) study we covered in class, infants will attend to a stimulus longer if they like it. So, we can give them different stimuli, and see which they like.
The online study session is now over. I hope it was helpful! If you have questions, you may still send them, and I'll try to answer them in the morning. Good luck with your studies, I'll see you all tomorrow.

Associative play is where kids are playing with similar toys and there IS some interaction. They aren't trying to work together for a common goal, but if two kids are building with playdough, now one might say "I need some yellow for my model of big bird" and the other might give up some yellow. The other child has no vested interest in the big bird model, and is probably building something completely different, but s/he is willing to help.
Informal code, on the other hand, is context DEPENDENT, meaning that you have to know a little about what is going on to understand it. Because informal code often uses slang, it can be ambiguous if you don't know the context. If I say, "I'm down" you need to know if I'm sad or happy to understand whether I mean "I'm upset" or "I understand". Informal code tends to use a narrow vocabulary, that may be understood only by the target audience.
Understanding that there are different codes to use when talking, and when we should use these codes is a part of pragmatics, but a very advanced part. We can use code switching as an example of how much development goes on in the understanding of pragmatics from preschool to the school years. By the time kids reach middle childhood, they can handle all the nuances that code switching requires. It is a great leap from the preschool child's embarrassing failure to understand pragmatics.
