A survey of how 17 recent experimental psychology textbooks treated the subject of random assignment of subjects to groups for purposes of experimentation is discussed. Findings indicate that the textbooks generally gave favorable coverage to the practice. Further research might improve this simplistic understanding. (Author/DB)

Carrying capacity (the use level at which total satisfactions or benefits are mazimized) is not equatable to highest-use levels, since some visitors to recreational areas desire solitude and undisturbed environment--for these, an alternative definition for "capacity" should take into consideration the use level demanded after considering costs.…

This experiment demonstrated that people can utilize relative situational frequency of occurrence to differentiate similary categorizable target items in paired-associate learning. (Editor)

Discusses reasons for including prosody in the management of language impairment in children and presents a classification framework that includes four categories of prosodic problems: dysprosody (pitch, loudness, duration, and pausing), prosodic disability (tempo, intonation, stress, and rhythm), prosodic disturbance (interaction disruption), and…

Loglinear unidimensional and multidimensional Rasch models are considered for analysis of repeated observations of polytomous indicators with ordered response categories. Reparameterizations and parameter restrictions are provided that facilitate specification of a variety of hypotheses about latent processes of change. Use of the models is…

Standards can be used as tools for standardization or customization. To accelerate learning for all students, standards must reject the dominant standardization (sorting) approach to education. Standards should represent attainment levels, be divorced from timetables and age levels, apply also to nonacademic areas, allow choice within limits, and…
