In this chapter we are introduced to psychology in terms of its history and its specialties. We will use this first assignment conference to explore some of the specialties in psychology. Your task in this first conference is twofold. First you are to visit the Websites below and explore some of the specialties in psychology. You are not choosing topics but sub-disciplines and areas of study. In your answer, tell us which one interests you most and why. Next you are to find a website related to the area that interests you most. Give us the URL and tell us a little about that Website. You may not repeat a related Website about one of the specialties that has already been posted. You may choose the same area as someone else.

This is a model of a core sample taken from a tree, cut down in 2014. You can find the age of the tree by counting all the annual rings. Remember, each space between two grooves is one annual ring and represents one year of growth. Do not count the pith or bark as these are not annual rings. How old was the tree when it was cut down?(if you get a slightly different number than the correct one indicated below, it is ok, the lines can make your eyes criss-cross) 47 85 22 67 64
