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 S0 targets. Lower panel: Sπ 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 +π/2 (upward triangle and diamond) and −π/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 Nπ0πSπ as a function of the inner-band (N0) 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.
