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

I developed an open-source survey framework called formr as a summer side gig.

comment Free online survey and diary software for conducting experience sampling studies
@what Yeah, you can also work around such limitations, but of course it's nicer if the platform handles it natively and there's not so much potential for user error and all that.

MyExperience works with Windows phones only, so that's a quite limited userbase, but it looks like it has an impressive feature set.

@what Thanks! Yes, I get those mails too. They're free (for a limited number of replies I think), but not open source. Also, I think they don't offer diary features.

comment Images on personal computers - Which aspect of size to keep constant?
@Ana We can't do it with our program (it's a web-based study). We could ask participants to change it every time, but I think they won't like that. This would also result in different displayed sizes...

comment Will Our Brain Speed Reduce As Our Memory “Mail Boxes” Fill Up?
I find the question why we we filter what more interesting too. Still, back-of-the-envelope calculations (other estimates are way below your 2^86bn) like that don't tell us very much about the amount of meaningful information that can be stored and retrieved again. An important question from evolutionary psych would be: Why do we "afford" brains that can store more information than we could ever hope to learn in the information age, even less in the ancestral environment? How many people can go past fluency in four languages? How many TV series until you start confusing characters?

comment Will Our Brain Speed Reduce As Our Memory “Mail Boxes” Fill Up?
'it is not true that our memory can "fill up"-- i.e., that we have a limited capacity for knowledge in general'. I agree with most of your answer and it probably never does fill up in a lifetime (and I don't know what to make of speculative estimates like these, but of course our brains do not have the capacity to store the position of every atom in our brains or something like that.

@Jon Because we've got an internal solution at my uni that we consider releasing into open source, but it will be a lot of work and if we'd be reinventing a less well-rounded wheel... That was clearer in the original question which was closed, because whether it's worth the effort is subjective. Revelation and Qualvu seem to be oriented towards qualitative research, I couldn't find Luminosity easily.

For commercial solutions I only know Qualtrics and I heard they're also fairly new to this, ie apparently you can't get a mobile experience sampling app going in a week. But yes I'm looking for open source, though simply free ones wouldn't hurt either. I'm not aware of any either. @Jon

@jon Name one. I'm in this field and I don't share your perception.

comment Is the Myer Briggs Type indicator (MBTI) a reasonable scientific theory?
They might. They might not. I'm saying I haven't heard that it actually improves company outcomes or teamwork. If it did, I'd probably have heard, considering how good they are at marketing their product. I think it's mainly used because people like the type descriptions they get due to the Forer effect.

comment Is the Myer Briggs Type indicator (MBTI) a reasonable scientific theory?
It's been used often, yes, but what permits you to say they "gain some high level insights into their staff and potential methods for structuring organizations and leading teams"? Sounds a bit marketing-speak for my ears and as far as I know the MBTI is not particularly useful in an organizational psych. setting, just widespread.

comment Public domain scientific intelligence test available for use in research
I also think PEBL is great, but why is this the accepted answer? I only see some subtests that relate to IQ, but the PEBL tests don't meet your requirement #2, there are no norms. @Jeromy what did you end up using?

comment 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.

comment 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)?
