  1. Hi! I can’t seem to access the pdf document you listed as an example for informed consent? Thanks, really appreciate the resources 🙂

  2. Hi Travis,

    Thanks so much for this and my school did buy your Class Activities this year, which my colleague finds most helpful (I did my planning before I knew it had been purchased).

    I showed your video about which IAs work and some of my students chose from it.

    I’m new to IB Psychology (and Psychology generally) so the IA is a bit of a mystery. I have two questions about two of the studies you suggested (which my students then chose). If you can help that would be much appreciated.

    1. For the facial feedback hypothesis/Kleinke one, measuring the effects is confusing (to me at least). Should one use a Brief Mood Introspection Scale (BMIS) before the photographs are used and then after or just after? And how many/which moods should be included?

    2. For the Colour in Context Theory, three of my students want to do the anagram experiment from the Blue or Red Study. Is there a way to simplify it? Might we just choose neutral and avoidance words to see if red is more effective than blue in this context? And would changing from speed of solving the anagrams to accuracy of solving them in a short set time be fine?

    Sorry if the questions are silly.

    1. Post

      1) From memory, my students chose a mood scale (maybe PANAS, but anything appropriate that the students find or create) and they measured change of mood. Choice of mood could be decided by students – they should take as much ownership as possible.
      2) These seems fine. Again, the more of these decisions the students can think through, the better. It will also make it easier for them when they come to do things like explaining their materials.
      No silly questions in IB Psych, or at least these aren’t some!
