There are at least two problems with measuring high intelligence: (1) Any IQ test has a maximum difficulty. That means that all subjects above a certain intelligence answer all questions correctly and get the same maximum score. This is called the "ceiling effect". Now you might say, that we simply need to construct a test that is difficult enough for even ...

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 ...

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 ...

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, 1974 has more about it). Also there are other measures: percentiles,DQI, z scores etc... you have formulas to recalculate, ...

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 ...

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 ...

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 ...

In clinical psychology, two kinds of general personality tests are in use today. One kind of test is not a specialized clinical test but tests personality in general. These tests are used outside of clinical contexts as well. There are many models of personality and a multitude of tests to measure personality according to each model, but the most popular ...

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 ...

There are no personality models in which the factors are orthogonal in the strict sense of being at 90 degrees from one another, unless an orthogonal rotation method is used to extract them. I think you meant to say that the Big Five factors are less independent (or more strongly inter-correlated) relative to the factors in other models. Whether or not one ...

Hm, tricky. To be told you are stupid over and over makes you stupid. I believe this is often a learned thing; a vicious circle. It is also about people around her not being able to change their view of her. This is entirely human, but certainly detrimental to many children. And grown-ups. I think I would not force her to work in groups, not put emphasis ...

How many personality factors are there? The history of personality testing can be summarised in terms of an initial period where there was a vast number of personality traits. In response to this, there have been various attempts to synthesise these traits into a smaller number of underlying factors. There is a huge literature on this process (e.g., Digman, ...

I'm not familiar with all tests out there, but I'll give an example from the fourth revision of the Wechsler Adult Intelligence Scale (WAIS-IV), one of the more popular tests. The time to complete the whole test does not matter (as long as you complete it in one go without long breaks). Usually testing takes between one and two hours, but if you test very ...

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

I'm currently working on a similar project and wanted to share some info. A recent paper reports a similar concern but also a solution via the iPad's built in mic. http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0057364 "The touch screen alone cannot be used for high temporal resolution measurements because of the inherent delay ...

This previous answer talks about evidence for a global or possibly two factor model partially explaining the correlations between the Big 5. In general this global factor may reflect some form of positive, well-being, social adjustment type variance. More generally, having orthogonal factors is desirable from a parsimony perspective. It's useful when ...

I assume you are talking about a difference in neural activity? The difference in processing of targets and distracters does not come from their relative frequency, but from their task-relevance: you are paying attention to the targets, thus increasing gain. In auditory MMN, this attention component becomes evident slightly later than the prediction ...

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 ...

In addition to the ressources that @Damien has provided I would like to give you a very brief "tutorial": Factor scores for a subject are defined as the sum of the scores of that subject on the items that belong to a factor, multiplied by their respective factor loadings. It doesn't really matter if you go with the standardized or with the unstandardized ...

To answer your general question, many psychology experiment delivery systems, and even general programming languages could be used to present a set of trials where participants provide responses regarding pairs of visual stimuli. In particular, I've found Inquisit to be a good option if you want to deliver the experiment online. If you examine the task ...

I think a good option would be to use a general purpose language. For example, I once used Visual Basic to program a task that allowed for dragging elements around a display. The IDE for Visual Studio makes it easier to create GUIs. You could readily include a background image and so forth. You could also record location of visual elements and each action ...

The basic idea is that you get a sample population. Let's say you have 100 people. You give each of those a creativity rating through some process. Afterwards you give every person in the sample population a stack of questions. You run statistical tests to determine which of those questions correlate with someone being creative. You keep all the questions ...

The MMPI calculates scale scores from dichotomous responses; hence those scale scores – the constructs of actual interpretive interest – are roughly continuous, or at least polytomous. Yes, there are very many other tests that can assess personality traits that can aid in diagnosis. I'm not sure what you mean by "mature", and I hesitate to judge their ...

I've done quite a lot of work on running experiments online over the last while, and have put together some of the code I've found useful in a project tentatively titled PsychScript. You will still need to actually program the experiment yourself in JavaScript, but with PsychScript you can do this by modifying a template and changing things around a little, ...

This is a Mac related answer - I'm sure there are equivalent applications on other platforms. When I'm doing usability testing on prototypes we use a combination of OmniGraffle or Keynote and Silverback. Silverback records all the interactions on the screen (will highlight when they click etc.) and will also use the built-in iSight camera to record a video ...

At our institute (at a university), all experiments are custom programmed, mostly in Python, often using PsychoPy, or in MATLAB. We have staff, from post-docs to student assistants, that do nothing but write code (such as packages for R). If you plan to do more than one experiment in your life, I would strongly recommend to learn programming them. You'd be ...
