For many domains aesthetic appreciation has proven to be highly reliable. Evaluations of facial attractiveness, for instance, show high internal consistencies and impressively high inter-rater reliabilities, even across cultures. This indicates general mechanisms underlying such evaluations. It is, however, also obvious that our taste for specific objects is not always stable-in some realms suc...

Results of a Monte Carlo study of exploratory factor analysis demonstrate that in studies characterized by low sample sizes the population factor structure can be adequately recovered if communalities are high, model error is low, and few factors are retained. These are conditions likely to be encountered in behavior genetics research involving mean scores obtained from sets of inbred strains. ...

Dealing with a surface’s form is an essential part of any topographical study of the said surface’s roughness. We present here a method for automatic correction of the form, using very simple concepts to solve a problem where top notch technologies were not enough mature to tackle. After explaining how well known mathematical tools such as the correlation function relate to this problem, we wil...

OBJECTIVE To examine the intra- and inter-rater reliability of the Action Research Arm Test (ARAT) at the item level after stroke. DESIGN An intra-rater and inter-rater reliability study. SUBJECTS Thirty-five participants (median age 62 years, median time post-stroke 22 months) with impaired upper extremity function after stroke were included in the study. METHODS Two physiotherapists sim...
