"Science" refers to a methodology for obtaining knowledge, and often to the knowledge itself as well. Science is often confused with another term "technology", that refers to the application of such knowledge for practical uses. Some people might incorrectly refer to "computers" and "cars" as examples of "science", when in fact they are examples of "...

Here are a few options. I have not tried them yet personally.
As mentioned below, the rtdists package in R is able to fit both LBA and diffusion models.
Other Options
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:

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 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 &...

For the diffusion model, there is also Eric-Jan Wagenmakers' "EZ-diffusion model", which you can find here.
This paper compares three different pieces of software for estimation of diffusion model parameters:

A study that used the field setting you describe is done by Bateson et al. (2006).
As for the mechanism, they write:
we believe that images of eyes motivate cooperative behaviour because they induce a perception in participants of being watched. Although participants were not actually observed in either of our experimental conditions, the human ...

OpenSesame is a recent entry that is cross-platform and seems to promote GUI-based design while allowing customization via Python scripting.
It can be found at their website (link above). A recent article has references and summarizes 16 other tools as well (including some reported in the other stackexchange responses). I found great video tutorials and ...

Disclaimer: As you have noted yourself, there aren't very many scientific researches on the topic. The only main points that I can derive are generally of blogs or sketchy speculations. As such, you are supposed to take this answer with a grain of salt.

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

You might look for examples in the Witt, Donnellan & Orlando (2011). They tested subject motivation in a psychology subject pool to see how it varied among groups. There may be follow up studies. Looking through similar studies will give you an idea of the kinds of things people use to assess. This is not a standardized line of research (yet).

I think it's a basic concept of experimental design that you have control groups. So for example, if you want to study the effect of X (e.g., a drug) on Y (e.g., performance), you could manipulate X (e.g., give half the drug and the other half no drug) and randomly assign the participants to either group.
Random assignment is a strategy for making the groups ...

Ethics of Feedback:
The APA's code of ethics (2010) as well as the Advisory Group on Conducting Research on the Internet (AGCRI) report (2004) summarize ethical issues related to conducting offline and online psychological research. Feedback is normal in psychological experiments, and researchers are encouraged to debrief participants, before, immediately ...

After researching this a bit more, I believe this is actually a biology question, not a physics one.
The specific term I believe you're searching for is Trichromacy, which Wikipedia defines as:
Trichromacy or trichromaticism is the condition of possessing three independent channels for conveying color information, derived from the three different cone ...

The study basically concludes that in a population of males (and I ...

There are a few factors that could contribute to differences between online versus in-lab reaction time measurement.
Hardware variation
Participants in an online experiment will use their own computers to complete the task, which will result in lots of variation in hardware. Many studies have looked at how hardware variations affect response time ...

Chunking leverages long-term memory for the chunks, i.e. we recognize and remember much easier the familiar chunks, sometimes algorithmically. This is much easier explained in the domain of letters/words, e.g. we'd recognize USA as substring among random letters. Similarly most would recognize the pattern 1945 (WWII end) by paired association, or 12321 ...

Overview: It seems like quite a bit of research has been conducted with experience sampling methodologies looking at daily variations in mood and activity. It is an interesting question as to how best tease out the effect on mood of time of day per se and activities associated with time of day on variations. It also seems like there are individual ...

The three levels of the Stroop test you describe are the following:

It's obvious that people will move more when awake or doing exercise compared to being asleep or resting, however actigraphy provides a quantitative way to measure that. Therefore actigraphy is useful for studying sleep-wake cycles, activity-rest cycles and circadian rhythms. They have been shown to be reliable in determining when a subject is awake or ...

The experiment you are referring to is usually called the ultimatum game, and was first experimentally tested by Güth, Schmittberger, and Schwarze in 1982 [1].

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-...

There are many granulations of the objective-subjective distinction. The most objective would be the behaviorism which says it is meaningless to reason about anything except how environmental stimulus leads directly to observed behavior. This camp was popular in psychology during the time of B.F. Skinner, but now is seldom followed by people outside of ...

I recently completed a study involving physical ergonomics of rifles. We monitored heart rate and respiration using the Zephyr BioHarness. It seemed to work pretty well.
It also monitors movement of the user, if that is of interest to you.
To get data out, it is possible to compile a report and export it to CSV, which works well if you need to do ...

In short: none that I could find. Indeed, it's a very one-way relationship - the more you drink the worse reaction time gets. However, there is a starting point, which is generally put around .02-.06 depending on your chosen study - below that threshold the effect of BAL on reaction times is difficult to pin down. Most studies I found showed that below .05% ...

It's a little unclear to me from what you've said that your efforts are truly affecting your brother's ideas. It's also unclear whether those ideas are objectively bad, or whether you should be trying to change them. In general, we have to be careful to avoid recommending specific actions for specific people here.
That being said, the general phenomenon you ...

Visual acuity is highest in the foveal region, namely around 1/60 of a degree, or 1 minute of arc (1 MAR). At about 30 degrees of eccentricity, visual acuity is reduced to anywhere between 1.5 and 10 MAR when determined by a shape recognition task, as shown in Fig. 1 taken from Lie, 1980:
A later study (Anderson et al., 1991) shows the following picture:
