EXP_KLINGEL2022 - Experiments of Klingel & Laback (2022)

Usage:

[] = exp_klingel2022(flag)

Description:

exp_klingel2022(flag) reproduces figures of the study from Klingel & Laback (2022).

The following flags can be specified

'fig3' Reproduce Fig.3: Pretest ILD weights for each frequency band, averaged across azimuths. Blue circles show the results of experiment 1, red triangles of experiment 2. ILD weights gradually increase for single-band conditions from low (794-1260 Hz), to mid-low (1414-1782 Hz), to mid-high (2245-2828 Hz), to high (3564-4490 Hz). The multiband condition shows ILD weights similar to the mid-low band.
'fig4' Reproduce Fig.4: ILD weights as a function of azimuth for each frequency band (columns) and group (rows; top row shows ITD groups, bottom row shows ILD groups). ILD weights gradually increase from low- to high-frequency stimuli and on average are lower for lateral azimuths. Significant weight changes from pre- to posttest were observed for the ILD group in experiment 1 for the high-frequency band as well as in experiment 2 for the mid-high-frequency band. Additionally, a significant weight change from pre- to posttest was observed for the ITD group in experiment 1 for the mid-low- frequency band at 9 deg azimuth as well as in experiment 2 at 39 deg azimuth.

Additional info about the data:

'wILD_exp1'

ILD weights of experiment 1

  • first dimension: azimuth (3, 9, 15, 21 deg)
  • second dimension: frequency band / testing time (multiband pretest, low pretest, mid-low pretest, mid-high pretest, high pretest, multi posttest, low posttest, mid-low posttest, mid-high posttest, high posttest)
  • third dimension: subject (odd numbers belong to ITD group, even numbers belong to ILD group)
'wILD_exp2'

ILD weights of experiment 2

  • first dimension: azimuth (3, 9, 15, 21, 27, 33, 39 deg)
  • second dimension: frequency band / testing time (mid-low pretest, mid-high pretest, mid-low posttest, mid-high posttest)
  • third dimension: subject (odd numbers belong to ITD group, even numbers belong to ILD group)
