A compact participant-level dataset derived from Experiments 1A and 1B of Chetverikov and Hansmann-Roth (2026). In Exp. 1A the high-noise stimulus had SD = 20 degrees; in Exp. 1B it had SD = 45 degrees. Low-noise stimuli had SD = 5 degrees in both samples.
Usage
data(memory_noise)Source
Derived from the public behavioral dataset at https://osf.io/kqb8t/. The package subset is based on the canonical CHR2026 representation used for model comparison.
Details
Only unequal-noise trials are included. Bias is estimated with the same weighted probability-density asymmetry approach used in the paper and averaged over target/non-target dissimilarities from 1 to 44 degrees, the range in which Experiments 1A and 1B showed the relative-noise interaction. Positive values indicate attraction toward the competing non-target and negative values indicate repulsion.
participant. An anonymized participant identifier, unique across Experiments 1A and 1B.
experiment. Between-subject sample:
"Exp. 1A"or"Exp. 1B".high_noise_sd. High stimulus-noise standard deviation used in the sample (20 or 45 degrees).
relative_noise. Ordered within-subject factor:
"target less noisy"or"target more noisy".bias_percent. Density-asymmetry bias in percentage points. Positive values indicate attraction toward the non-target; negative values indicate repulsion.
n_trials. Number of non-outlier unequal-noise trials contributing to the weighted bias curve.
