This paper discusses grounded theory as one of the qualitative research designs. It describes how grounded theory generates from data. Three phases of grounded theory--open coding, axial coding, and selective coding--are discussed, along with some of the issues which are the source of debate among grounded theorists, especially between its…

This article reviews evidence and theories concerning the nature of stimulus representations in Pavlovian conditioning. It focuses on the elemental approach developed in stimulus sampling theory (R. C. Atkinson & W. K. Estes, 1963; R. R. Bush & F. Mosteller, 1951b) and extended by I. P. L. McLaren and N. J. Mackintosh (2000, 2002) and contrasts…

In an effort to generate innovative treatments, the National Institute of Mental Health has made translational research for alleviating mental illness a major funding priority. Although translational research is a powerful approach for moving basic science findings into novel treatments, it remains ambiguous and rarely implemented in psychology.…

The sampling distribution is a common source of misuse and misunderstanding in the study of statistics. The sampling distribution, underlying distribution, and the Central Limit Theorem are all interconnected in defining and explaining the proper use of the sampling distribution of various statistics. The sampling distribution of a statistic is…

Although popular literature cites between 25,000 and 100,000 parental child snatchings a year, no empirical studies have been conducted to support this estimate. To determine an empirical estimate of the extent of parental child snatchings, telephone interviews were conducted by Louis Harris and Associates with a representative cross section of…

Described herein are formulas and computational procedures for estimating the mean and second through fourth central moments of universe scores through multiple matrix sampling. Additionally, procedures are given for approximating the standard error associated with each estimate. All procedures are applicable when items are scored either…

Examines the question of how large a sample must be in order to produce empirical Bayes estimates which are preferable to other commonly used estimates, such as proportion correct observed score. (Author/RC)

Author considered the proper use of the LSD-type drugs, variously called hallucinogenic, mind-altering, mind-revealing, or psychedelic, and sampled the views of responsible researchers on the use of these drugs for mental health and for the study of the human mind and development. (Author/RK)

This research represents an attempt to look closely at the actions which children are expexcted to perform in the early stages of reading and writing when taught by systematic methods, containing a phonic ingredient. (Author)

This paper presents the finding of an investigation for determining course achievement utilizing the statistical technique of path analysis. (Author)

Participants in the D-19 symposium on aquatic sampling and measurement for water pollution assessment were informed that determining the extent of waste water stream pollution is not a cut and dry procedure. Topics discussed include field sampling, representative sampling from storm sewers, suggested sampler features and application of improved…

A procedure for testing heterogeneity of variance is developed which generalizes readily to complex, multi-factor experimental designs. Monte Carlo studies indicate that the Z-variance test statistic presented here yields results equivalent to other familiar tests for heterogeneity of variance in simple one-way designs where comparisons are…

Designs for sequential sampling procedures that adapt to cumulative information are discussed. A familiar illustration is the play-the-winner rule in which there are two treatments; after a random start, the same treatment is continued as long as each successive subject registers a success. When a failure occurs, the other treatment is used until…

Two investigations examined whether incentives increase the number of survey returns from former students and whether ideographic characteristics, incentives, and multiple mail-outs influence the perceptions of respondents. Survey responses of 125 (Study 1) and 67 (Study 2) baccalaureate graduates in education were used. The survey included 43…
