My research group has gone pure python for coding experiments; we've been burned too many times by glitches and implicit behaviour in boxed experiment-building software to bother trusting it. Moving from a point-and-click experiment design interface to pure code does have a large learning curve, and you want to be careful to model your own code on well ...

I'd suggest checking out the Linear Ballistic Accumulator (Donkin et al., 2011) model for a scenario like this. While LBA can be used to model any number of alternatives in a speeded choice task, to model signal detection you'd want to model just two accumulators, one for the "signal" response and one for the "no signal" response. With this scenario, ...

This effect is referred to as Piaget's Theory of Conservation. Piaget constructed an experiement where children would be shown a tall, narrow glass of colored water (to make it clearly visible in a clear glass) and two shorter, wider glasses of the same exact size. A single amount of water would be distributed in both small glasses. If a child is asked ...

MANOVA is definitely a bad idea given that one dv is continuous and the other is binomial. After exploring a number of different approaches to combining RT and accuracy data, I've come to conclude that the best current approach is to use linear ballistic accumulator model (e.g., see Donkin et al 2011). The LBA is a simple (structurally and computationally) ...

Here are a few options. I have not tried them yet personally. LBA Scott Brown has a copy of Donkin et al (2009) on his web page with some code in R, Excel, and WinBUGS for fitting the LBA model: http://www.newcl.org/publications/DonkinAverellEtAl2009BRM.pdf http://www.newcl.org/members/chris/fitLBA.zip Diffusion model The Diffussion model is ...

I would recommend Matlab and the Psychophysics Toolbox. It lets you display all sorts of stimuli in full-screen mode, and it lets you capture key strokes and mouse clicks.

Veridicality is a term used in cognitive science; it is the degree to which your internal representation of the world accurately reflects the external world. Some background Since the work on Humberto Maturana in color perception, it was considered very important to not always focus on the fact that there is some external stimuli to be cognized by the ...

A paper comparing the performance of Inverse Efficiency Scores and diffusion models for the quantification of RT and accuracy can be found here. Rach et al. (2011) "On quantifying multisensory interaction effects in reaction time and detection rate " Psychological Research Volume 75, Number 2, 77-94, DOI , PDF

There is currently a lot of debate surrounding what questions Bayesian modeling is appropriate for answering within cognitive science, as well what makes a "poor model." Unfortunately these become extremely thorny issues very quickly, partly because what is called "bayesian modeling" actually refers to a rather heterogeneous set of approaches and ...

In addition to Mike's suggestion, see the Ratcliff diffusion model and variants thereof. E.g.: Ratcliff, R., & Rouder, J. N. (1998). Modeling response times for two–choice decisions. Psychological Science, 9, 347–356. Ratcliff, R., & Tuerlinckx, F. (2002). Estimating parameters of the diffusion model: Approaches to dealing with contaminant reaction ...

There are a variety of models solving accuracy and RT that have been pretty well tested and LBA is probably fine (I haven't used it). If you don't want to go that far there is a rather simple way to analyze data controlling for SAT that has much better mathematical properties than IE scores (which, as Mike said were named by me, but offhandedly proposed by ...

I've studied this a little bit within the context of timing responses to personality test items. General models of reading speed look at both the time to read the words as well as to comprehend. From memory, eye tracking studies have shown how the eyes will often back track to confusing parts of a sentence (apologies for lack of reference). Some general ...

Yes! The International Affective Picture System (IAPS) is widely used. From the IAPS instruction manual: The International Affective Picture System (IAPS) is being developed to provide a set of normative emotional stimuli for experimental investigations of emotion and attention. The goal is to develop a large set of standardized, ...

I would first like to discuss the concept of lateralization and clear up a common misconception about hemispheric dominance. "A brain is considered to be asymmetrical (or lateralized) if one side (hemisphere or other brain region) is structurally different from the other and/or performs a different set of functions." (Bisazza et al., 1998). A good ...

Procedures like this are often called "funnel debriefing" procedures, and they basically consist of an extended version of what you already had in mind. You begin with some very general questions about the nature of the experiment (e.g., "Do you have any initial thoughts or reactions about this experiment?"), then move on to some questions that are slightly ...

Programs/packages for EEG analysis There are decent MatLab toolboxes with good tutorials for for the analysis of EEG data. The EEGLAB toolbox (tutorial) can be operated by both GUI and command-line (and script). The fieldtrip toolbox (tutorial) is mainly operated by command line / script. Of course there are also (commercial) software packages for EEG ...

This is an experiment testing the Stroop effect, named after John Ridley Stroop who studied it in 1935, and often called a Stroop experiment. It is a classic and well understood experiment and has now become a neuropsychological test for use in clinical settings, usually called the Stroop test.

@CHCH has provided a good broad overview, but I thought I would also append some specific experiments that are considered to be a weakness of Bayesian models. The whole theme of this answer is an extension of Tversky and Kahneman's program of rationality-violation. All of these experiments can be fitted by some Bayesian-ish just-so model of the sort Bowers ...

The basic approach that you are describing sounds like inverse efficiency scores (e.g., see Townsend and Ashby, 1978,1983), which are measured as $$\frac{r}{1-e} = \frac{r}{c}$$ where $r$ is reaction time, $e$ is proportion error, and $c$ is proportion correct. John Christie provides a critique of inverse efficiency scores here or see the discussion in ...

This is not exactly my area, but I suspect it simply may not be anyone's area. It is not clear from the research literature that speaking rhythmically does help get into a trance, mostly because it is not currently clear that "trance" is distinct from other forms of dissociation (though dissociation is often confusingly described as "trance-like" or ...

I use the FieldTrip toolbox in Matlab to analyze my own modified auditory MMN experiment :) But I use MEG, so I don't have that many software options. The toolbox is very powerful but it has a steep learning curve and I would recommend it only if you already have both Matlab and EEG data analysis experience. I don't analyze my data in the classical MMN way ...

Great question. There are two software packages that might be interesting to you: I have tried to run EPrime in a virtual machine on my Mac and it was a catastrophe. As I found out it used to work, but some of the later updates made it impossible. In the process of figuring this out, I came across PsyScope X. It is an actively developed open source ...

It sounds like you're looking for a platform on which to implement computerized adaptive tests (since subsequent questions are contingent on prior responses). I found Concerto, which is based in R and MySQL, but allows some flexibility in presentation (it says it uses HTML directly, but you could probably couple it with another language).

Another option is to program in C/C++ using the Tscope library. If you're not experienced with programming, it's a bit tricky at first, but I'd say it pays off in the end. Tscope is a C/C++ experiment programming library for cognitive scientists. It is distributed under the Gnu Public License, and is intended to run on Windows 2000 and XP platforms. ...

I use Adobe Flash. My colleague Yana Weinstein has written a book on Flash Programming for the Social & Behavioral Sciences that should be out next month. I'm a contributor and helped write some of it! Check it out by clicking here.

This is a bit of a tangential answer, but hopefully still useful. When we give humans noisy data, we can basically think of them as some sort of Bayesian inference machines that try to figure out what the function that data came from looks like. The important thing we then need to know, is how strong of a bias (prior) humans have towards expecting certain ...

WebExp is a client/server based psychology/linguistics experiment creation/running system written in Java. It is freely available. A subject types in the appropriate web address and they see the experiment pages that have been created; obviously you have to have access to a server on which the experiment software+configuration files are running. It ...

You should probably also check out: Pleskac & Busemeyer (2010). Two-stage dynamic signal detection: A theory of choice, decision time, and confidence. Psychological Review. Also, I believe Busemeyer has a dynamic signal detection theory paper but I don't know that it has been published. The Pleskac & Busemeyer paper probably draws on this ...

If you really wanted to know you could use models of reading behaviour - e.g. EZ-Reader or Swift. The Rayner reviews are the classic go-to to outlne this kind of thing: Rayner, K. (2009). Eye movements and attention in reading, scene perception, and visual search. The Quarterly Journal of Experimental Psychology (2006) (Vol. 62, pp. 1457-506). It will ...
