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 ...

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 ...

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 ...

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 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 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 ...

If your goal is to find a set of shapes that are unique and easily distinguishable from each other, you might be interested in stimuli that get used in visual statistical learning experiments (e.g. Fiser & Aslin, 2002; Turk-Browne, Junge, & Scholl, 2005). The same set of shapes tends to get used across multiple studies in this literature. Some ...

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 ...

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 ...

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, ...

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

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 ...

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 ...

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 ...

People use a wide range of language to describe measurement points in repeated measures design. For example if you measured some dependent variable on multiple occasions you might have something like: baseline (B) treatment week 1 (T1) treatment week 2 (T2) post treatment (F0) six month follow up (F6) one year follow (F12) Obviously such a design has ...

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 ...

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 ...

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 ...

There are several commonly used measures of Short Term Memory (STM). Memory span: lists of items are presented sequentially and the participant has to repeat each list after it ends. The lists become progressively longer. The most common variant is called Digit span, in which the items in the lists are spoken digits. Another common variant is called ...

There are systematic ways to compare similar tests and determine which test best fits your needs. Construct Definition Identify the constructs (in this case, traits or abilities) you are interested in and clearly define the meaning of each construct. Cognitive performance can encompass many domains, including memory, processing speed, psychomotor ...

NEO FFI Scoring The test manual describes how to calculate raw scores for the NEO-FFI. If you have been asked to do an analysis of the NEO-FFI then you should be given access to relevant details in the test manual. If you don't have access, you may wish to contact your local psychology department. They will often have a test library with the NEO-FFI manual. ...

There is a program called Paradigm that allows you to build millisecond-accurate neurocognitive experiments for iOS devices. The experiment builder is like E-Prime but easier to use. The app is available in the app store. You upload your experiments to a Dropbox and then log in to access them through the app. It's pretty flexible. I've used it to build ...
