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 ...

To my knowledge, there is no adjusted RMSD. RMSD, unlike $R^2$, isn't typically used to compare models across the literature. $R^2$ represents the proportion of variance explained by the model, a construct which translates well across different experimental designs. Adjusted $R^2$ distorts this by accounting for the number of parameters in your model, but ...

HH doesn't "count ions", it pretends the reservoirs are infinite. Specifically, the "reversal potential" for each ion species is a constant. This constant is calculated from the Goldman Hodgkins Katz equation which uses the concentrations on either side of the membrane to calculate the reversal potential given the concentration gradient. We could ...

In psychology, you have two types of measurement: either a trained observer judges the behavior of the subjects without them having to actively partake in any kind of test or experiment; or the test subjects fill in a test (self-report) or take part in an experiment. Obviously the mood in a city cannot be re-created and measured in an experiment, but you ...

Mario Liotti and Don M. Tucker (Brain Asymmetry, MIT, 1996) attempt to explain that the 'corticolimbic architecture is not left/right, but dorsal/ventral". In their opinion, the reason for hemispheric asymmetries can be found in the asymmetries of the dorsal and ventral systems. They proposed that emotional behavior could be interpreted by analyzing the ...

The question of how "rapid" learning could be possible relates to Hume's problem of induction -- how can we learn so much from so little. Historically, in both philosophy and psychology, the solution has fallen into one of two camps: either some form of the knowledge was already there to begin with (a 'nativist' view), or we use statistical inference to ...

There are at least 3 ways to discount SSE (or RMSE) by the number of free params: $$\text{adjusted RMSE} = \sqrt{\frac{SSE}{n - k}}$$ $$AIC = n \times ln\left(\frac{SSE}{n}\right) - k \times ln(n)$$ $$BIC = n \times ln\left(\frac{SSE}{n}\right) - 2 \times k$$ or in computer code style: k = number of free params n = number of DV's SSE = sum of ...

It's a little unclear what you're asking. In general, psychologists try to build models that are parsimonious; this often means only introducing new parameters (particularly free parameters) into a model when they are absolutely necessary. You are right that with a sufficient number of free parameters, one can build a model that fits the data perfectly. But ...

You may be interested in the FARS model from Fagg and Arbib (1999) that describes the interaction of the two visual streams in the primate brain during object grasping. The article What Puts the How in Where? Tool Use and the Divided Visual Streams Hypothesis (2007) makes use of the dorsal/ventral streams to explain our ability to use complex tool. As Frey ...

In the context of this question, neuroimager refers to a commercial grade EEG/EMG device. For example the emotiv epoch (considered a high end of what is commercially available) had 3 or 6 electrodes. The output of these electrodes is available to a developer through a software interface created by the manufacturer. I believe that Jsn is seeking ideas of ...

Henderson summarizes very well a number of approaches on human gaze control during real-world scenes and tasks. http://cvcl.mit.edu/iap05/henderson_03.pdf In a nutshell, our visual system combines knowledge about the task (e.g. color of the search target) and external audio/visual stimuli (saliency) to control our gaze inside a scene. Quite insightful about ...
