I study psychology and work in a research group as an assistant. My main interests are evolution, individual differences, personality development and intelligence.

Is variation in human brain size related to mental functioning? I think Rushton is your guy. scholar.google.com/… springerlink.com/content/r173v725160tn626 |

What are different ways to determine centroids of fMRI activation, their drawbacks and perks? Thanks for your reply, Jeff. This is pretty much what the authors did and what I took issue with though (except for using clustering which doesn't seem to be a remedy for "throwing away information", might even be worse). I know how classical hypothesis testing works, but if the research question is about the separation of areas (not about "is this voxel active", which it never should be), then I think this multistage analysis discards information that could have served to improve the estimate. Maybe this can not be resolved in a frequentist approach. |

What are different ways to determine centroids of fMRI activation, their drawbacks and perks? Thanks for your answer. I realize this is also a statistical question, but because it seems to be a common method in neuroscience even though the deficits are obvious, I thought I'd ask here. Their scans weren't spatially normalized, they looked at intraindividual differences (conditions were within-subject) which makes more sense I suppose (or do I misunderstand you?). What do you consider the reason data like this is not commonly analyzed in the fashion you propose (I've been told it isn't, this old article maybe doesn't do the field justice)? |
