Due to the strikes in weeks
10 and 11, we lost two days of tutorials, affecting some, but not all, tutorial
classes. We do not want this to result in the different number of contact hours
for different tutorial groups. It was decided to modify the tutorial programme
for this week to allow all the students to cover the same material and
prepare for the next week's class.
This week, all the students need to do TWO THINGS on their own:
1. Read the handout about the Signal detection theory, and/or the recommended reading (B. Goldstein (2002 or an earlier edition of "Sensation and perception": Appendix on Signal detection theory). The handout will be distributed in the Tuesday lecture. Copies will also be placed in the pigeon hole in front of Tanja's office, GT 505, on Tuesday morning.
2. Do a computer-based experiment relevant for the discussion of the Signal detection theory. It takes no more than 20 minutes to do the experiment. It is called Dot field, and can be found in the usual 3210 folder on the computers in your classroom. To avoid overcrowding and unnecessary loss of time, please follow the suggestions below, if at all possible:
- come to your regular tutorial
time if you are in a Wednesday group
- come at 9:30 am on Wednesday, if your regular tutorial time is Tuesday 9 am
or Tuesday 10 am
- come at 5:30 pm on Wednesday if your regular tute is Tuesday,1 pm
- come at 10 am, Friday, if you your regular tute is Thursday, 2 pm
- come at 10:30 am, Friday, if you your regular tute is Thursday, 3 pm
- come anytime between 11 am and 1 pm on Friday, if none of the other times
suits you.
NOTE: Be patient with the task. It is meant to be hard! WHEN YOU FINISH THE EXPERIMENT, WRITE DOWN THE TABLE WITH YOUR RESULTS BEFORE CLICKING OK. Bring the results with you to the tutorial in week 12.
