these are so usefull :)

You put the hippocampi was "larger," it's actually "denser," you'd get no marks in the exam for saying the posterior hippocampus were larger than non-taxi drivers.

i pretty sure that it was 16 taxi drivers and 15 normal people

Hey

Thanks for putting the videos up, it's very kind of you!

Can you tell me the sampling method that Maguire used? I can't find it anywhere on the internet or in my textbooks

Thanks!

Having delved further into the article, it makes sense:

The VBM method used scans of 50 males as controls.

The pixel counting method used 'a precisely age-matched

sample of 16 normal controls taken from the 50 used in the VBM

analysis'

Aaah that sucks! thanks for clarifying.

[ThePsychologyTeacher]

From the original article published in The Proceedings of the National Academy of Science (97: 4398-403):

'The scans of 50 right handed males who did not drive taxis were included in the analyses for comparison with the taxi drivers.'

Perhaps a note to the textbook authors to check the facts if they publish a 2nd edition, and a cautionary tale about relying on textbook authority!

Thanks for pointing that out!

This is interesting:

I've double checked in three textbooks. One (the one I used) says the control group was 16 men, another just says that 50 MRI scans were used but doesn't say from how many people, and the third says 50 males.

How odd. I'll have a look at the original article...

[fantasykasia]

Woah woah woah. There were 50 men in the control group!

@fantasykasia Alright calm down! you're right though!
