General thoughts on brain training: Lumosity is a commercial tool that aims to improve brain functioning. In general, I am sceptical of the potential for "brain training programs" to improve cognitive functioning in a generalised way (e.g., see this Nature discussion). Practice is powerful, but tends to be domain specific. So if you want to become skilled ...

The IPIP may provide what you are looking for. This IPIP Website is intended to provide rapid access to measures of individual differences, all in the public domain, to be developed conjointly among scientists worldwide. In general, the scientific literature tends to focus more on a dimensional approach based on the Big 5 model of personality than ...

I was alerted to your post here and would like to respond to a non-technical side of the question. I'm an Intellectual Property Assistant for CPP, Inc., publisher of the MBTI® assessment tool. I help protect the instrument's trademarks and copyrights, and ensure ethical use of the instrument. The names MBTI®, Myers-Briggs®, and Myers-Briggs Type Indicator®...

IQ scores in general: An IQ score is a normative score. The norm group is typically defined as the general population, and where the respondent is a child, the norm group is defined in terms of the general population of children of that same age. IQ scores typically have a mean of 100 and a standard deviation of 15. In order to get an estimate of ...

A useful model for topics like this comes from McCrae and Costa (1999): There's quite a lot more going on here than is pertinent to your question, but note that influences originate from biological bases on the top left, and from external influences on the upper right. Everything else is modeled as an effect of mediated, dynamic processes between these two.....

Because it has been a few years since Jeromy's original answer, and because I just read a very apt article, I will venture an update on the state of the field with respect to the BPI's validity. Overall, despite more research into brain training and Lumosity, there is little to no peer-reviewed evidence supporting the Lumosity BPI's validity, nor evidence ...

What you are asking for does not really exist, no serious IQ test would ever give a score of 160. IQ scores get swamped with noise more than ~30 points from the mean. For example, an IQ of 160 means you are are more intelligent than 99.996% percent of people while an IQ of 150 means you are more intelligent than 99.957% of people. No test could claim to ...

Frustration is measured in various ways. In psychology, frustration is seen as occurring when an anticipated reward or outcome is blocked (Berkowitz, 1989). The block can be either internal (the person’s lack of skill, knowledge) or external (environment, situation) (Shorkey & Crocker, 1981). Some papers and measures focus on the block itself (Dollard et ...

The first one is a test if a child has understood conservation of matter. It is an example of a conservation task. These belong to the tests used in the framework of Piaget to test what stage of development a child is in. Here is a video demonstration of the cookie task. Here is another question on this site pertaining to a different conservation task. The ...

Firmin et al. (2008) tested the validity of a handful of online IQ tests by having college students complete IQ tests at three different websites and also complete a validated lab measure, the Reynolds Intellectual Assessment Scales (RIAS). They found that there were moderate correlations ($r$ values were around 0.4 to 0.5) between some of the online tests ...

Raven (2000) provides norms for Raven matrices for different age groups. Here is how you interpret it. Burke (1985) provide different groups norms. You can use different scales like IQ (which is very old term used in Piaget. DeVries (below) has more about it). Also there are other measures: percentiles, DQI, Z scores, etc... you have formulas to ...

Yes, they are still in use, and they provide rather bad information. My former advisor once worked with a clinician who told him that the main reason they're any better than using the weather report as a projective stimulus is that the Rorschach tests have been in use as-is for decades. Hence we have a better understanding of how people normally react to ...

The three levels of the Stroop test you describe are the following: Congruent stimuli Incongruent stimuli Incongruent stimuli alternated with the Reverse Stroop effect

To add to the existing answers (of which @what's gets special mention), an issue I don't think has really been addressed is the statistical reason for it being so difficult to measure extremely high IQs. By design, IQ is scaled so that it's normally distributed, with a mean of 100, and a standard deviation (SD) of 15. A well known feature of the normal ...

There is a large general literature evaluating the degree to which personality tests predict job performance. In particular see for example the review by Barrick et al (2001). In general such reviews find that personality measures provide a small but meaningful prediction of job performance. Ipsative testing So in general, you are asking about how ...

Short answer Yes. Background A cursory Google Scholar search with the key terms Gender Dysphoria Questionnaire brought up The Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults. If you wish to search for more related inventories you can look further using keywords like 'gender dysphoria' + 'inventory' / 'test' / 'diagnosis'. ...

Short answer Any intelligence test will be designed for a certain target population. That target population's score is set at an index of 100 for the standard IQ test. The same test applied to people from a different cultural background, or other socioeconomic status may yield numbers that are unreliable, as they my not understand the question (albeit ...

The task sounds like a match-to-sample task which is indeed used in working memory studies. In this test participants are presented with a sample stimulus and have to judge whether or not following stimuli resemble this particular stimulus. Depending on the time span between the presentation of the sample stimulus and the following stimuli this task is ...

The Open Extended Jungian Type Scales is a open source alternative to the Myers-Briggs Type Indicator. The Open Extended Jungian Type Scales was developed to be an open source alternative to the Myers-Briggs Type Indicator. The OEJTS was developed by empirically selecting items that differentiated among persons who identified as one of the Myers-Briggs ...

There is now an app available on the iPad offering a cognitive test battery. It is a commercial application but fairly inexpensive. Joggle Research adapts several widely validated tests to the touch platform. Test result data is stored and instantly accessible on a cloud service (with a free tier to try it out). Some here have noted potential limitations ...

I just found out about ICAR. The International Cognitive Ability Resource is a public-domain assessment tool which aims to encourage the broader assessment of cognitive abilities in psychology and other social sciences and facilitate neuropsychological assessment in medical research and practice. The collaborators working on this project believe ...

Interesting that you mention ethics. Regardless of the validity of the MBTI (or rather lack thereof - try searching the web for independent professional opinions rather than just listening to the Myers-Briggs Foundation marketing), my main problem with it is that I personally believe it is foremost a money-making scam. The Myers-Briggs Foundation will not ...

In the standard version of the task there are "good" decks (overall positive payoff) and "bad" decks (overall negative payoff), so the optimal strategy is to figure out which ones are the good decks and stick with those. In principle, which deck is which should be randomized, but I don't know if your version implements that. There are also many variations ...

A child's mind is certainly not tabula rasa; language acquisition patterns in children suggest that they have an inborn module for it — domain-specific and, while flexible, clearly incompletely flexible. The children would probably have the same troubles with constructions of spiders and snakes; the modules that we are said to have for those species concern ...

Typically, questionnaires where all items are on the same response scale are coded differently to composite variables where you have variables on different metrics (e.g., a set of ability tests). Sums and means: For questionnaires like yours, you would commonly just take the mean or the sum of items that belong to a given subscale (note that you may need to ...
