data = data_baumgartner2017looming(dataFlag,measure) data = data_baumgartner2017looming(fig)
data | structure that contains either HRTFs (id, and Obj) or experimental results including raw and averaged data (rawData,`data`, opional meta information). Statisitcs (stat) and figure handles (fig) are provided if requested. |
data_baumgartner2017looming provides individually measured HRTFs and experimental results from Baumgartner et al. (2017). Use the fig flag to obtain data shown in figures from Baumgartner et al. (2017).
The dataFlag flag may be used to choose between HRTFs and various experimental results:
'hrtf' | HRTFs used in all experiments. |
'pretest' | Behavioral results of pre-test. |
'exp1' | Behavioral or ERP results of Exp. I. Default. |
'exp2' | Behavioral results of Exp. II. |
The measure flag may be one of:
'judgment' | Judgment of relative distance change (motion direction). Default. |
'rt' | Response time. |
'erp' | ERP magnitude measures. |
The fig flag may be one of:
'fig1b' | Effect of spectral contrast manipulation according to factor C on magnitude responses of listener-specific stimuli of Exp. I (B, Top) as well as their frequency-specific and overall loudness changes relative to C = 1. Shaded areas denote ??1 standard error of the mean (SEM; N = 15). Note that changes in overall loudness oppose the intended effect of contrast switch. |
'fig2' | Behavioral responses were more consistent for sounds perceived as approaching compared to sounds perceived as receding if instantaneous spectral changes were presented in continuous stimuli. Mean behavioral responses in the 3?AFC motion discrimination task of Exp. I (fist figure; N = 15) and the 2?AFC motion discrimination task of Exp. II (second figure; N = 13). Results of Exp. II are separated between trials presenting instantaneous but continuous (Left; as in Exp. I) and discontinuous (Right) spectral contrast switches. Decreasing spectral contrast switches (orange lines) were predominantly perceived as approaching (orange triangles), increasing spectral contrast switches (green lines) as receding (green triangles), and constant spectral contrasts (no lines) as static (gray squares). Statistical analyses focused on these predominant response associations. Values reflect mean ??1 SEM. |
'fig3a' | Extracted N1 and P2 amplitudes evoked by stimulus onset. Error bars reflect SEM. |
'fig3b' | Extracted N1 and P2 amplitudes evoked by stimulus switch. Error bars reflect SEM. |
'fig3c' | Significant cluster in time and space that is distinctive between decreasing and increasing spectral contrasts. (no plotting) |
Additional flags may be:
'plot' | Plot results as published. |
'no_plot' | No plots. Default. |
'stat' | Analyze and display inferential statistics. |
'nostat' | No statistics. Default. |
'onset' | To use onset ERPs. |
'switch' | To use switch-ERPs. Default. |
