I'm wondering if there is a database of objects (either word or picture targets) that have been rated by a good number of people (>=30) on Osgood et al.'s semantic differential scales (e.g., fast-slow, thin-wide, etc.)?

How do I determine the number of participants needed to achieve X power, with a small effect size (assuming f2 of .02), for a multivariate regression? As far as I can tell G*Power can only do...

I know that when there is close to zero variance in either random effect, a perfect correlation can mean that the model isn't able to estimate both effects. However, I have a good deal of variance...

My psychometric scale contains 38 items in total, with 4 subscales (20, 6, 6 & 6 items respectively? Can i run a factor analysis for each subscale rather than the scale as a whole for the...
