This paper describes some of the more spectacular range effects reported in the literature. (Author)

The primary purpose of this article is to describe, justify, and elaborate a preliminary quantitative model for a subset of the letter-identification process. (Author)

A model for inferential accuracy in clinical judgments was proposed in which two major processes, sensitivity and threshold, was hypothesized. (Editor/RK)

This paper describes and tests a two-stage model for a "semantic congruity effect" in comparative judgments. (Editor)

Discusses use of the computer to solve the specific scheduling problems in assigning umpires to American League baseball games and assigning crews of officials to Atlantic Coast Conference football and basketball games. Scheduling variables that complicate the process and make manual scheduling almost impossible are described. (MBR)

Develops a systems approach to planning as a means of increasing organizational effectiveness. A model of the planning process is presented, the various components are described in terms of implementation, and pragmatic strategies and considerations for an academic library are suggested; data tables and a flow chart are included.

When shown a pair of digits and asked to select the larger of the two, subjects make their choice more quickly as the numerical difference between the digits increases. Presents and tests a semantic coding model that can explain this and all previous results. (Editor)

The present experiments test two plausible interpretations of the effect of frequency on relative recency judgments. (Editor)

Flow charts, tables, and lists are used to illustrate a program evaluation model to be used in evaluating compensatory studies in higher education. Student progress is followed along an identification/selection/admission chart, incorporating program goals and student need measurement. Measures of individual and collective student progress are…

The purpose of this research was to develop and field test a new flowchart model prescribing specific operations for tryout and revision of prototype multi-media self-instructional treatments. The methods and results of the following four phases of the study are described: (1) design of a MK I flowchart model based on a review of the literature;…
