Re: Got the de Boer & Kuyper paper; question about correlated stimulus components



Beware, however, of interactions between nonlinearities in your biological system and higher-order correlations in your stimulus that persist even after application of decorrelation or regularization techniques.

Theunissen and colleagues (http://www.jneurosci.org/content/20/6/2315.abstract) looked at the effect of stimulus correlation in reverse correlation. That work was based on a number of previous studies. There is also a review by Wu and colleagues  (http://www.annualreviews.org/doi/abs/10.1146/annurev.neuro.29.051605.113024) that covers the use of natural stimuli in reverse correlation.

Subject: Got the de Boer & Kuyper paper; question about correlated stimulus components

 

Got it, thank you very much for you fast responses!

 

A related question: the classical reverse correlation technique usually uses the "white noise" idea and assumes that all stimulus components (e.g., acoustic energy in different spectral regions, or all the picture elements in

an image) are *uncorrelated*. In contrast, in studies on "psychophysical reverse correlation", we use multiple regression analyses which are not affected by correlated cues/stimulus components (e.g., http://dx.doi.org/10.1371/journal.pone.0050184).

 

Is anyone aware of a technique for the "classical" reverse correlation as in the de Boer paper that can be used with correlated stimulus components?

Here it is. Looks interesting; should give it a read myself.

Dear list,

 

does anyone happen to have access to this classical paper on reverse correlation and could send me a PDF….?
