I am continuing to learn more about the primitive number systems in human infants and lemurs as the summer progresses. In the baby lab, we have finished up the Ordinal Low-Cognitive Demand with 9 and 11 month olds, and are now moving on to different things (although I will still be using the Ordinal-LCD paradigm for my project). 11 month olds are now doing an Ordinal Transfer study, which shows sequences of stimuli that increase. They are habituated to these images, and then tested on the opposite condition (i.e. if they are habituated to ascending sequences they are tested on descending ones). We are beginning to set up two visit experiments with 9 month olds; on their first visit we show them a paradigm in which we know they succeed (where surface area, number and perimiter I believe all increase or decease), and then on their second we show them stimuli where only numerosities increase or decrease. We think that perhaps if we give these infants some sort of "practice" they may succeed.

The DLC is always fun, and this week will be a little different. We are "shaping" two new female mongoose lemurs (Guadalupe and Eduardo)-teaching them how to use the touch screen (contrary to what many believe, just because Rosalita may have watched Eduardo do the experiment, she still has no idea how to even approach the computer). Aristides will also start again with the Risk paradigm after being out sick for quite a while. Aristides will be so excited, as whenever we walk by with the machine he thinks it's his turn and is ready to go! Finally he'll be able to. Also thanks to Aristides (a ringtail) I have data to use for my project. Aristides has finished the experiment that Teres is now running (that I am using for my project).

Hope everyone had a great 4th and a weekend! This summer is going by just way too fast....
