Scientists studying the matter generally believe multitasking, and women's superiority at it, to be a myth. Men come out slightly better multitaskers than women but there's not really any meaningful difference. The way it's defined is critical though; it's being able to do two things that typically require focal attention at the exact same time. For ...

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: http://www.newcl.org/publications/...

In speaking to constructs vs. measures, I believe that the difference is clear and implied in your background: constructs are that which cannot be directly measured (but we assume exists), where measures are directly measurable attributes that we assume relate to the construct. The process you seem to be questioning is that of the operational definition, or ...

The question which of these two descriptions is correct? is perhaps natural in the context of, say, someone studying for an examination. Epistemologists might suggest that a better formulation would be is either of these correct? However, as stated here there are clear reasons for preferring the first formulation to the second. I shall first explain why, ...

The Computational Theory of Mind is not that the mind does some form of computation in the wide sense of computation. Rather, look at the examples for the CToM given in the Wikipedia article; people like Fodor, Pinker, Marr. Their view is very much the opposite to the Connectionist position of West Coast scientists like Rumelhart, Elman and McClelland. Both ...

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: von Ravenzwaaij D., & Oberauer, K. (2009). How to use the diffusion model: Parameter recovery of three methods: EZ, fast-dm, and DMAT. ...

Humans actually exhibit both slow and fast learning and they have somewhat different properties. One distinction is between "declarative" memory (for example, facts like "tigers have stripes" or "Paris is the capital of France") and "procedural" learning (such as perceptuo-motor skills like riding a bike or playing a musical instrument). Declarative memory ...

My answer is probably a weird hodgepodge of sometimes poorly explained stuff, but hopefully it's coherent enough :P For many decades in psychology, we've had a mechanistic stimulus-organism-response understanding of the brain. That is, a stimulus triggers an internal psychological process, which produces some behavioral response. One of the major ...

In general, there are two types of 'complexity' that are studied. Usually, when people talk about 'complexity', especially on the internet, they mean Santa Fe Institute style complexity. This is a vague and poorly defined concept that has struggled for a number of years without making significant progress. It uses pretty words, but has yet to deliver on any ...

I don't think there's any evidence suggesting that mindfulness or meditation are the opposite of self-regulation. In arguing why, it'll be useful to define terms. Meditation and mindfulness First off, meditation and mindfulness are not the same thing. Meditation generally refers to a family of practices for investigating or inducing different states of ...

Apologies in advance for the long answer. I tried to narrow down the scope by focusing on only a single construct, and only a single aspect of validity, and it still turned out like an essay... Let's take intelligence research as an example. This work started with an intelligence concept – a fairly vague and ambiguous idea about a personality trait that ...

ACT-R can best be summarized with this (tiny but more recent) graph: ACT-R is a cognitive architecture that tries to explain as much of human behavior as possible with as little rules as possible. It works at a high level of abstraction and came down to a list of so-called "modules", each having its own functions. The exact mechanisms of each of these ...

One common way of framing numerical cognition is in terms of a "mental number line". This mental number line is thought to have a logarithmic scale, so perceived differences are inversely proportional to their magnitude. For example, the difference between 6 and 7 is perceived as bigger than the difference between 76 and 77. This is just a variant of the ...

Unfortunately, in psychology and cognitive sciences (and some parts of neuroscience) absolutely no mathematical training is given beyond the highschool level (intro stats, basics of linear algebra in $\mathbb{R}^2$ and $\mathbb{R}^3$, and intro calc; see also this answer). To make this relatable, I will compare understanding dynamics sytems to literature, ...

I think this recent paper fits your requirements. It considers biological plausibility by showing that the number of neurons required in the proposed method is within a reasonable size for the human brain, and dismisses a series of unreasonable models. Specifically, they create a neural network using the Neural Engineering Framework (NEF) and the Semantic ...

I like to think of multitasking as rapid task switching. See Pashler's (2000) article for the implications of "multitasking." References Pashler, H. (2000). Task switching and multitask performance.

In general, what you're looking for is a biologically plausible model of reinforcement learning and/or conditioning. I know of two publications in particular that address this. The first is A Biologically Plausible Spiking Neuron Model of Fear Conditioning and the second is A Spiking Neural Integrator Model of the Adaptive Control of Action by the Medial ...

It appears that there is little scientific backing for Jung's theories. As these theories were first suggested at the start of the 20th century they have had a considerable amount of time to receive scientific support. If they were accepted by scientists it therefore seems like they would have been widely used and cited by scholars in the interim period. ...

Wickens et al. (2003) is the earliest I'm aware of: Wickens, C. D., Goh, J., Helleberg, J., Horrey, W. J., & Talleur, D. A. (2003). Attentional models of multitask pilot performance using advanced display technology. Human Factors: The Journal of the Human Factors and Ergonomics Society, 45(3), 360-380. Actually, in that paper he cites Wickens et al. (...

As per the comments to the question, human research observing this distinction does exist. CHCH possibly alludes to an article by Gläscher, Daw, Dayan and O'Doherty (2010) which concisely defines the difference between model-free learning and model-based learning: Reinforcement learning (RL) uses sequential experience with situations (“states”) and ...

This question might be better handled by biology.SE. I think the short answer is that there are many pain receptors around the skull. From wikipedia: The brain tissue itself is not sensitive to pain because it lacks pain receptors. Rather, the pain is caused by disturbance of the pain-sensitive structures around the brain. Nine areas of the head and ...

From personal observation, the consensus seems to be that the two streams hypothesis is an oversimplification of the truth, albeit a useful one. The primary reason that this hypothesis is seen as an oversimplification is because there is a lot of cross-talk between the two streams. For example, Zanon et al. (2010) provides evidence for functional ...

The Benjamin Franklin Effect is generally cited as being an example of cognitive dissonance, which is when your brain struggles to reconcile your beliefs with your actions. So let’s say your beliefs about your job are that you deserve to be paid a higher rate, you deserve to be treated more respectfully by your employer and your skills are being wasted in ...

Thoughts on the paper The paper appears to provide a high level overview of the role of mathematics in cognitive science. I'm not a sufficient expert in the overall field of cognitive science where I'd feel comfortable to truly judge the accuracy of the overall synthesis that Andler (2012) provides. That said, much of the paper is about providing examples ...

Has dom-ter loops theory been expressed formally in any kind of Jungian function theory study? Based on a reasonably diverse search of Google Scholar, Web of Science and Scopus, I am concluding that dominant-tertiary loop theory seems to be an original proposal by the author of the forum post cited by the question author. It appears to be a theory which has ...
