The vocal tract's motion during speech is a complex patterning of the movement of many different articulators according to many different time functions. Understanding this myriad of gestures is important to a number of different disciplines including automatic speech recognition, speech and language pathologies, speech motor control, and experimental phonetics. Central issues are the accurate ...

It is an honor and privilege to be asked to comment on the 12 papers in this special issue of the Journal of Pediatric Psychology on Family Assessment. In most of the papers in this issue, the family member who was assessed was a parent whose child had been diagnosed with a serious chronic condition. It should be clear that when a family member is assessed that measurement reflects not only the...

Public authorities are increasingly sharing sets of open data. These data are often preprocessed (e.g. smoothened, aggregated) to avoid to expose sensible data, while trying to preserve their reliability. We present two procedures for tackling the lack of methods for measuring the open data reliability. The first procedure is based on a comparison between open and closed data, and the second de...

Visual inspection of single-case data is the primary method of interpretation of the effects of an independent variable on a dependent variable in applied behavior analysis. The purpose of the current study was to replicate and extend the results of DeProspero and Cohen (1979) by reexamining the consistency of visual analysis across raters. We recruited members of the board of editors and assoc...

The present paper is a description and summary of methods used in non-randomised cohort data where the comparability of the study groups usually is not granted. Such study groups are formed by a diagnostic or therapeutic intervention, or by other characteristics of the patient or the treatment environment. This is a typical situation in the analysis of registry data. The methods are presented t...

Rkeemment, Rushton affirmait qu 'il existe des diff~rences importantes dans les taux de criminalitg entre les groupes raciaux. Ses mthodes d'analyse statistique (l'analyse de variance), cependant, ne fait pas ressortir la grandeur de ces difflrences. Les auteurs ont rO-analys les donnes de Rushton et dmontrent qu 'il n 'y a pas de rapports fermes entre les facteurs (le coifficient de corr~latio...

In the first decade of the evidence-based era, which began in the mid-1990s, meta-analyses were used to scrutinize homeopathy for evidence of beneficial effects in medical conditions. In this review, meta-analyses including pooled data from placebo-controlled clinical trials of homeopathy and the aftermath in the form of debate articles were analyzed. In 1997 Klaus Linde and co-workers identifi...

Most probably, all life existing today on earth shares a common ancestry billions of years back in the past. A set of indispensable genes necessary for maintenance of basic cell functions were passed on from the unknown common ancestor to its extant descendants by asexual and/or sexual reproduction. During the course of evolution, the genes, the numbers of genes, their functions and the sizes o...

Although the typical study in psychology involves the quantitative analysis of contemporary research participants, occasionally psychologists will study historical persons or events. Moreover, these historical data may be analyzed using either qualitative or quantitative techniques. After giving examples from the subdisciplines of cognitive, developmental, differential, abnormal, and social psy...
