Week 4: Girls Just Want To Have Fun



Girls, they want to have fun.
Oh girls just want to have fun.
They want to have fun!
- Cyndi Lauper

YES! The girls just want to have fun. I'd say SMARTA is pretty fun for Celeste, Pandora, Pyxis, and Carme! And for some reason, Cyndi reminded me of the red ruffed lemurs.

This week I got to work with 2 new red ruffed lemurs. Pandora and her one-year old daughter Celeste joins the rotation to be part of my SMARTA color vision study. Celeste was very excited on her first day and her enthusiasm continues to the second day. She is currently my youngest participant. Celeste's mother, Pandora, was equally enthusiastic to participate in the study. Both had participated for two days and will continue their sessions next week.

Caught Celeste mid chewing craisins. Looks like she's very excited.

Pyxis continues to be cautious around SMARTA and gets easily distracted by her mate and son. Pyxis is a stark contrast from Pandora (and Celeste) where they are not distracted by the males and instead focus intently on SMARTA. Though at the end of the week,  Pyxis started to approach SMARTA immediately when the sessions start. Currently, we are only reinforcing her to sit in front of SMARTA so she'll station perfectly in front of SMARTA before we start reinforcing her to look at the screen. Towards the end of the week, Pyxis has started to pay attention to the SMARTA screen. These are crucial small details that we have to pay attention to so that we are not reinforcing bad or superstitious behavior when using SMARTA. This is Pyxis's second week and even though she doesn't share the same enthusiasm as Pandora and Celeste, it is very common for animals to be apprehensive to novel objects (especially a towering object that makes noise). Luckily, Pyxis is whistle trained (meaning she know what a whistle cue means) so it is very easy to reinforce her and that she probably knows she is doing something right when she hears the whistle. Craisins help a lot too ;)

Carme continues to have at least 2 sessions per week since I came back to Duke Lemur Center. We addressed her left hand preference and her tendency to touch the left square at the beginning of each trial regardless of what color the square is. We don't know if she is has trouble using her left hand to reach to right square or if it's a superstitious behavior. Over the past few weeks, she had progressed tremendously and we feel like she finally "got it" this week. We ran a few testing trials with her and I think we are comfortable enough to say that she had graduated from training to fully automated testing. She should be on testing sessions next week.
