The purpose of unbiased hit rate is to avoid invalid conclusions in cases where subjects indiscriminately use one (or only few) response options. To give an example (responses in rows, stimuli in columns): Happy Sad Angry Fearful Happy 1 0 0 1 Sad 7 8 6 5 Angry 0 0 0 0 ...

The Torrance Test of Creative Thinking is a good place to start. It scores for fluency (number of responses) as well as originality (statistical rarity of responses) and elaboration (level of detail) on a variety of different tasks. The validity of the TTCT has been examined with several long-term studies, so there is a fair amount of data on its ...

Amazon Mechanical Turk is perfect for something like this. In fact, tagging content is one of their default project types, so you should be able to just load in your images and use their template for tagging. If you haven't seen it before, MTurk is basically a labor marketplace for very small tasks. It works best for paying people a few cents to complete ...

Short answer: Representations are a noteworthy controversy in embodied or situated psychological theories. Can we explain behavior without reference to representations? Long answer: Most modern theories presume that information is represented somewhere, such as the brain, and that behavior is organized because that somewhere is organized. ...

I am not an expert on these scales, but my 2-cents worth would be the following, which are simple work-arounds to include all the data: Fine as is; Take the middle of the thick line (the 'average'); Take the center of the circle (draw a cross in it, the intersection is the middle); Apparently "0" - no pain; Take the tip as the marker; Apparently "100". As ...

Say your juvenile offender are on average 16 year old boys from Britain, and the control group consists of (on average) 16 year old British boys who haven't done anything wrong. The only difference between these groups are the fact one has a criminal record or not. If you would look at the true norm, you could be looking at the world wide norm of both boys ...

I am particularly concerned with whether or not the task load index could be considered an interval variable, Yup. This is a fundamental assumption people make when constructing, administering and analyzing any measure under the classical test theory (CTT) paradigm i.e. count items and add 'em up. That is to say, your variable is certainly treated ...

In Stevens' levels of measurement framework, the NASA-TLX is an ordinal scale, not an interval scale, because there is no way to know a priori how much "workload" each point corresponds to. In other words, we can only know how much workload a point corresponds to after observing the data from our sample. Indeed, Hart's own review of the NASA-TLX suggests ...

It depends on what you mean by manipulation check. Manipulation check to filter participants: A manipulation check is usually done to verify that some experimental manipulation has had some preliminary effect. For example, in one of my studies I asked people to answer a personality test (a) honestly, (b) as an ideal worker, and (c) as the worst possible ...

Just to help, here's an illustration of the sort of answer I'm looking for, though personally I'd be happy with any suggestions, even if less detailed than the first below. Long answer: On one hand, Pinker and Bloom (1990) argue that our language faculty is similar to our physical organs, in that they evolved as adaptations to evolutionary pressures. On the ...

The recent visual working memory literature has predominately used the method of adjustment. In particular, there is a lot of work using continuous color adjustment tasks: Wilken P., Ma W. (2004). A detection theory account of change detection. Journal of Vision, 4 (12): 11, 1120–1135. Zhang, W., & Luck, S. J. (2008). Discrete fixed-resolution ...

The question is a little vague, but here is a partial answer. There are a number of EEG systems available that are low-cost. Examples include Emotiv's EPOC System and the OpenBCI project. The former has been available in various models for some years now and it has been established that it records real EEG signals, as opposed to just recording signals ...

You kind of have to do some kind of baseline correction first (or a highpass filter on the unepoched data) because of slow drifting. Lowpass filtering before artifact rejection is fine as long as you don't ever go back to the unfiltered signal in your analyses. After that, you can either throw out trials that exceed a set threshold, or you can do a two-step ...

It was not an assumption; it was a decision. It allowed for better quantification, it gave an operational definition in increase in sensation, which allowed for more common ground in research between different labs. In a way, it's a definition by pure counting: when the subject feels a change in sensation, add one. Then this absolute scale is plotted against ...

This seems difficult for a number of reasons. First, are you interested in testing the retrieval of pre-existing semantic memories or the ability to form new semantic memories? It is entirely possible that exposure to nature increases one without the other, so be sure you're testing the one you're interested in (or both, carefully). Second, semantic ...

There actually is the same kind of controversy over depression. The French documentary Dépression, une épidémie mondiale nicely summarizes how a well-meant change in diagnostic criteria (from DSM-IV to DSM-5) backfired and the pharmacoceutical industry now use this to diagnose every sadness or exhaustion as depression with the intention to sell drugs and ...

We have developed an iPad cognitive test battery (CABPad) for use at bedside with stroke patients: www.cognisoft.info. It is used for research at two university hospitals in Copenhagen and a publication on validation is currently being prepared for publication (see this abstract from The International Stroke Conference, Feb 2015: L Willer, PM Pedersen, A ...

Researchers are trained to address this problem by using literature reviews to isolate the specific variables that should be of most interest. At the start of research you generally examine the knowns and unknowns in the particular area of interest, so as to determine the state of the art in that area. Once you know the state of the art you have a better ...

The hot sauce paradigm was reviewed as part of a paper discussing laboratory measures of aggression. They argued that the hot sauce paradigm's main advantages are that it is very economical, easily quantifiable, less likely than other methods to be interpreted competitively, and that it has ecological validity (Ritter and Eslea, 2005). Given the prevalence ...

This is an interesting methodological problem. On the one hand, it seems that any method which would present the halves to the correct eye, and only that eye, would entail a visible boundary, and any method with an invisible boundary would be unable to present the halves as desired. Virtual reality systems present stimuli to each eye separately (e.g., the ...

Tough question. I'm going to assume that the question pertains to measures which lack all the information you've outlined: test manual, validity studies, website and key articles, item content and normative comparisons. If these assumptions are correct, then what you are a describing is an insufficiently explained measure. I will argue that we necessarily ...

Since you mentioned the Stroop specifically, several versions of the Stroop task are available for Inquisit here. Randall Engle's lab also maintains a set of validated working memory tasks, which are available on request to researchers. They include full and shortened versions of operation-, symmetry-, reading- and rotation-span for E-Prime 2.0. Assuming I ...

when I was planning a pilot study in which we planned to use cross-modality matching I came across some studies. Human Factors and Ergonomics researchers seem to still use the Method of Adjustment. At least, I found a couple of conference papers in which they examined warning signals for cars. Unfortunately, I don't remember the titles but I think one of ...

It has been a while since the question was asked, but I am going to give my answer anyway. PsychoPy is really good and easy to use and is what I typically recommend people to use. However, I recently found the Python library Expyriment and it seems promising. Although you will have to write your own code there are available methods for creating the window, ...

Often, we learn about brain functions when parts of the brain become damaged. One famous example is that of Phineas Gage. He survived severe brain damage, and his character and abilities were noticeably different. From the article:- Some months after the accident, probably in about the middle of 1849, Phineas felt strong enough to resume work. But because ...

Method of adjustment is still in use in vision science, especially when dealing with illusions. Its major advantage over, for example, 2AFC tasks is the speed of estimation -- you need way less trials to measure the effect, which could be useful in clinical settings [1]. You could also try to search for "nulling" instead of "adjustment" -- nulling is the ...

In addition to studies of patient with particular focal lesions, brain function in particular areas can also be studies in other ways. For one, functions are often conserved between species so that studying animals can give some indication of the role of a brain region in humans. This may be done by applying lesions or through treatment with genetic or ...
