Participants at the last meeting of the Society for the Improvement of Psychological Science developed a list of >100 such datasets with some metadata such as topic, country, total number of participants, etc. The list is currently a collaborative wiki open to editing by anyone. List of open psychology datasets and aggregators Outside of psychology, there ...

As a matter of anecdote, I've used some of this data for teaching purposes, and I've heard of others doing the same. As Bryan notes, there is a list of journal articles that have used the data: https://openpsychometrics.org/_rawdata/cited/ This includes many well-regarded journals in personality and individual differences research. One main limitation is ...

Yes, the General Assessment of Functioning (GAF) score can be used for all psychiatric disorders. The GAF is not commonly used now as the DSM V has opted for the WHODAS 2.0 instead of GAF. There were fundamental problems with GAF including poor reliability with people who were less trained, cross-cultural variations and symptom severity tended to influence ...

Prefrontal cortex is most closely associated with the group of cognitive functions termed "executive function" - measures of executive function do not measure prefrontal cortex per se because (almost all) brain functions are not simply localized to one area, but one would expect major lesions of the prefrontal cortex to impair executive function, as would ...

When uncertain about a decision and you are aiming for an optimal outcome, Hastie and Dawes (2009), suggest that the choice be 1) based on your current assets (money, physiological state, psychological capacities, relationships, and feelings). 2) It is based on the possible consequences of the choice. 3) When the consequences are uncertain, their likelihood ...

First I should tell you that controlling for color in an online experiment is hopeless. Monitors display quite different colors, people run experiments in environments that have very different illuminations etc. There is no chance you could display equiluminant colors, which is already hard to do in the best of conditions, in an online experiment. However ...

What do you mean by uncertainty? Is it internal or external? I am heavily a category learning person, so I begin there. Even like that, there are many ways you can approach this: Uncertainty can be when you encounter something novel and have to generalize your experience to complete a task or make sense of things. People can behave systematically in those ...

In the measures subsection of the methods section in the paper you refer to (Gifford et al, 2004), you can see that Gifford et al. (2002) is cited when referring to the AIS questionnaire. However, I cannot seem to find this paper titled "Combining Bupropion SR with acceptance-based behavioral therapy for smoking cessation: Preliminary results from a ...

Questionnaires and measurement scales typically take a lot of revision and validation. Otherwise, it is very common that you measure things you don't intend to measure, are missing relevant options, or omit critical factors entirely. I'd recommend some piloting and to use existing and validated measures whenever possible. Some of your items sound ...

The psychology notation for standardized differences between group means is d. I.e., the difference between group differences divided by the within-group standard deviation. Note that there are some variants about which group is used or whether a pooled standard deviation is obtained. I.e., in your example: d = 0.3. If you want to report means and sds, ...

I'd recommend an ordinal scale. A nominal scale just labels classes without a < or > relation. Using this you would be limited to "immersive" and "not immersive" type of answers. This runs into the danger that experimental subjects might classify all your conditions as immersive or non-immersive respectively. That is, you might get little information. ...

Using Dunbar's number, and the inherent trade off that the more friends one has (quantity) the less time they can spend with each (quality). Time spent could be assumed to equate to friendship strength. I will note, however, that there is in fact a secondary level (of quality) to the time itself whereby how effectively one uses it with different friends, ...
