TL;DR: In this paper, a hierarchical model for factorial analysis-of-variance (ANOVA) is proposed, where all of the hypotheses associated with the traditional factorial ANOVA model (i.e., main effects and interactions) are conceptually independent and occupy the lowest levels of the hierarchy.

Abstract: Logically consistent (“coherent”) hypothesis-testing strategies for factorial analysis-of-variance (ANOVA) designs are proposed in the context of a hierarchical model. It is shown that all of the hypotheses associated with the “traditional” factorial ANOVA model (i.e., main effects and interactions) are conceptually independent and occupy the lowest levels of the hierarchy. A research example is presented to illustrate the kind of conclusions that legitimately follow from testing the traditional hypotheses on the one hand, versus a variety of alternative hypotheses on the other.

Cross-language differences in cue use for speech segmentation.

TL;DR: Stress realization in English versus Dutch encourages greater attention to suprasegmental variation by Dutch than by English listeners, allowing Dutch listeners to benefit from an informative pitch-movement cue even in an uncharacteristic position.

TL;DR: Overall, results suggest that, the CSP appears to be similarly effective in both cultures and thus, sufficiently sensitive to the culture of Dutch adults who stutter.

TL;DR: This chapter provides the opportunity to discuss a number of methodological and statistical “bugs” that I have detected creeping into psychological research in general, and into research on children’s learning in particular.

Benzodiazepine treatment can impair or spare extinction, depending on when it is given
TL;DR: It is suggested that the effectiveness of extinction will not be reduced when combined with a benzodiazepine if the patient has undergone some initial extinction drug-free.

Simultaneous test procedures-some theory of multiple comparisons'
TL;DR: The Simultaneous Test Procedure (STP) as discussed by the authors is a generalization of the notion of multiple comparisons for means, which was originally proposed by Aitchison and Roy.
A Procedure for Testing the Homogeneity of All Sets of Means in Analysis of Variance
TL;DR: In this paper, a procedure for testing the homogeneity of all sets contained in the set of all means involved in an analysis of variance is proposed, based on sums of squares between means within sets, using the same critical value as for the overall F-test.
