Sound disrupts short-term retention in working memory even when the sound is completely irrelevant and has to be ignored. The dominant view in the literature is that this type of disruption is essentially limited to so-called changing-state distractor sequences with acoustic changes between successive distractor objects (e.g., "ABABABAB") and does...

Sequences of auditory objects such as one-syllable words or brief sounds disrupt serial recall of visually presented targets even when the auditory objects are completely irrelevant for the task at hand. The token set size effect is a label for the claim that disruption increases only when moving from a 1-token distractor sequence (e.g., "AAAAAAAA"...

Intermediately inspecting the statistical data of a running experiment is justifiably referred to as a bad research practice. With only a few intermediate inspections, Type I error rates inflate to a multiple of the previously defined critical falpha. On the other hand, there are research areas where intermediately inspecting data is extremely desi...

Today, many experiments in the field of behavioral sciences are conducted using a computer. While there is a broad choice of computer programs facilitating the process of conducting experiments as well as programs for statistical analysis there are relatively few programs facilitating the intermediate step of data aggregation. ART has been develope...

In the time-intensity trading paradigm, trading ratios are inconsistent in that they differ as a function of which cue is to be adjusted by the listener. Two explanations have been offered: First, the regression model assumes a regression to the interaural parameters of a reference tone played in alternation with the test tone to cause the phenomen...

Lang and Buchner [J. Acoust. Soc. Am. 124, 3120-3131 (2008)] conducted trading experiments showing that the phenomenon of different trading ratios depending on which cue is adjusted by the listener is independent of the presentation of an explicit reference tone. Four experiments were conducted to test whether implicit reference tones during the pr...

When interaural time differences and interaural intensity differences are set into opposition, the measured trading ratio depends on which cue is adjusted by the listener. In an earlier article [Lang, A.-G., and Buchner, A., J. Acoust. Soc. Am. 124, 3120-3131 (2008)], four experiments showed that the perceived localization of a broad band sound for...

G*Power is a free power analysis program for a variety of statistical tests. We present extensions and improvements of the version introduced by Faul, Erdfelder, Lang, and Buchner (2007) in the domain of correlation and regression analyses. In the new version, we have added procedures to analyze the power of tests based on (1) single-sample tetrach...

When setting interaural time differences and interaural intensity differences into opposition the measured trading ratio depends on which of the cues is adjusted by the listener. This paper provides some evidence that the different trading ratios may be an effect of a shift of attention toward the to-be-adjusted cue. The experiments consisted of tw...

G*Power (Erdfelder, Faul, & Buchner, 1996) was designed as a general stand-alone power analysis program for statistical tests commonly used in social and behavioral research. G*Power 3 is a major extension of, and improvement over, the previous versions. It runs on widely used computer platforms (i.e., Windows XP, Windows Vista, and Mac OS X 10.4)...
