THE AUDITORY MODELING TOOLBOX
exp_eurich2022
Reproduces figures from Eurich et al. (2022)
Usage:
data = exp_eurich2022(flag)
Description:
exp_eurich2022(flag) reproduces figures of the study from Eurich et al. (2022)
The following flags can be specified:
| 'fig3' | Reproduces Figure 3 from Eurich et al. (2022). Experimental data from van der Heijden and Trahiotis (1999) (symbols). The continuous lines show the predictions of the presented model including the across-channel incoherence interference. The dashed lines show predictions for ODN excluding interference (single- channel version), equivalent to Encke and Dietz (2022). Upper panel: Detection thresholds with \(S_0\) targets. Lower panel: \(S_\pi\) targets. |
| 'fig4' | Reproduces Figure 4. Experimental data from Marquardt and McAlpine (2009) (symbols) and model predictions (lines). Detection thresholds are given as function of the inner-band bandwidth. The inner band contains delayed noise (triangles) or opposingly delayed noises (diamonds and bul- lets) with a fixed ITD of 1 ms while the flanking bands have a constant IPD of \(+\pi/2\) (upward triangle and diamond) and \(-\pi/2\), or vice versa (down- ward triangle and bullet). Continuous and dashed lines again show predic- tions with and without across-frequency incoherence interference, respectively. |
| 'fig5' | Reproduces Figure 5. Symbols denote data from binaural detection experiments with the configuration \(N_{\pi 0\pi} S\pi\) as a function of the inner-band (\(N_0\)) bandwidth; continuous and dotted line: model prediction with and without across-incoherence incoherence interference, respectively. |
Further, cache flags (see amt_cache) and plot flags can be specified:
| 'plot' | Plot the output of the experiment. Default. |
| 'no_plot' | Don't plot, only return data. |
| 'accurate' | Accurate results, slow calculations, but as originally done to reproduce figures from Eurich et al. (2022). Default. |
| 'fast' | Faster calculations by using a subset of conditions, less repetitions, and shorter signals. These results won't be cached. |
