EXP_LABACK2023
Figures from Laback (2023)

Usage:

exp_laback2023('fig5')
exp_laback2023('fig5','i_cond',X)

Description:

exp_laback2023('fig5') predicts the effect of various types of precursors on ILD-based perceived lateralization. It is based on AN model by Smalt et al. (2014), which is a binaural version of the AN model by Zilany et al. (2014), that involves ipsi- and contralateral cochlear compression control via efferent feedback.

exp_laback2023('fig5','i_cond',X); displays predictions for the specific condition, with X being:

1 : Condition 'noP'

2 : Condition 'Central'

3 : Condition 'Ipsi'

4 : Condition 'Contra'

Examples:

To display Fig.5, which shows the predictions for all four models use :

exp_laback2023('fig5');
exp_laback2023_1_1.png
exp_laback2023_1_2.png
exp_laback2023_1_3.png
exp_laback2023_1_4.png

Note: The last row of the AMT's Fig. 5 shows results drastically different than those in Laback's Fig. 5. The results in other rows also are not fully compliant. This is a bug and the AMT Team is working on that (see Issue #247). The model status is thus "untrusted" for the moment.
