Laura Mills-Smith will present “Developmental and Clinical Implications of Problems in Effect Size Reporting” on Wednesday, March 12, from 3:30–4:30 p.m. in Uhler Hall, Room 114.
The guidelines of the American Psychological Association
(APA) require that effect size
estimates (ESE) be reported along with statistical results to provide a better
indication of the magnitude of the association between factors and dependent
measures. Hence, psychological science journals
now require authors to provide ES estimates.
This presentation will report on a
research project that examined recent infant-specific research from select
journals to examine the accuracy and interpretative value of ESEs. Demographics, sample size, design, and
statistical data were coded from published articles presenting experiments on
infants using behavioral methods. Descriptive and distribution statistics were
calculated for the following variables: (1) commonly used statistical tests, (2)
effect size parameters, and (3) effect size interpretations. The results will
be described, and the implications of the results in terms of this specific
literature, as well as other areas of psychology (e.g., clinical implications)
will also be discussed.
Laura Mills-Smith, MS, is a doctoral
