IB Psychology: Antonova (2011)

The study by Antonova et al (2011) can be used to address the question of how neurotransmitters play a role in behaviour. The IB accepts cognitive processes as a form of behaviour.Antonova"s research supports Rogers and Kesner"s research on the role of acetylcholine in the encoding of spatial memory in rats. The research is one of the first to test the role of acetylcholine in the encoding of cognitive maps in humans.

hi John, just wanted to confirm that in the new curriculum IB will still accept memory as evidenced by time taken to complete a maze as a behaviour

John Crane 15 January 2018 - 04:58

Yes. Behaviour is inclusive of cognitive processes. Sometimes, as specified in the guide, cognitive processes may be singled out. For example, they can ask the role of culture in behaviour or on cognitive processing.

thank you. also in the last paragraph of procedure it says there was a significant difference in time taken to find the pole but the evaluation says this was not a significant difference? could you please confirm the results for me

sorry just re-reading that, the last paragraph of the results make it seems like time taken was a significant difference but there was no significant difference for accuracy. but in fact there was no significant difference for either. is that correct? also does this contradict localisation of function of spatial memory in the hippocampus, as in, if participants still find the pole well they must use other brain regions do so if their hippocampal activity is reduced

Dear Megan, I have fixed the wording with the hope of making it clearer for students. Let me know if that is better. As for localization of function, I don't think that this contradicts it, but just that specific aspects of spatial memory are in the hippocampus whereas other aspects are in other sections of the brain. In particular, this study focuses on allocentric spatial memory. I don't think that students need to know this, but the idea that although specific parts of the brain have specific responsibilities, they are often on a much more "micro" level than we discuss in class. The concept of memory is quite complex, so it is not a surprise that several parts of the brain interact in the creation of a memory.

thanks John

It appears that acetylcholine may play a key role in the encoding of spatial memories in humans, as well as in rats. Hi John, you have this sentence twice. : )

John Crane 2 April 2018 - 09:14

Thanks, Virginia. I was just trying to make my point.... :)

Hi John
The study - Rogers and Kesner (2007) - is this a typo? Should it be 2003?

John Crane 3 May 2018 - 05:11

Fixed. Thank you, Megan.
