A discussion of the simulated oral proficiency interview (SOPI), a type of semi-direct speaking test that models the format of the oral proficiency interview (OPI), describes its development and research and examines its usefulness. The test used for discussion is a tape-recorded test consisting of six parts, scored by a trained rater using the…

A recent survey of simulation studies concluded that an overwhelming majority of papers do not report a rationale for the number of iterations carried out in Monte Carlo robustness (MCR) experiments. The survey suggested that researchers might benefit from adopting a hypothesis testing strategy in the planning and reporting of simulation studies.…

A fly-only group (N=16) of Navy replacement pilots undergoing fleet readiness training in the SH-3 helicopter was compared with groups pre-trained on Device 2F64C with: (1) visual only (N=13); (2) no visual/no motion (N=14); and (3) one visual plus motion group (N=19). Groups were compared for their SH-3 helicopter performance in the transition…

Two reduced rank classification procedures, principal components classification and equal weights classification, are described and compared by a simulation study to the standard classification procedure to determine their feasibilities as alternative classification procedures. A justification for the development of these two reduced rank…

This paper describes a computer model that simulates experimental outcome data obtained by the manipulation of 13 independent variables reported in studies investigating the group risky shift. The model is intended as a tool for teaching research methods in an undergraduate course in social psychology. (Author)

A model is described to suggest how the visual system may keep track of perceived objects as their images move on the retina. (Author)

This booklet contains the specially printed answer choices for a written simulation test that is contained in TM 009 785. Only the directions and the section and item numbers are visible until the test takers have indicated their choices. In this test, rather than choosing answers to a fixed set of questions, the test taker chooses questions from…

INS, the Integrated Network Simulation language, puts simulation modeling into a network framework and automatically performs such programming activities as placing the problem into a next event structure, coding events, collecting statistics, monitoring status, and formatting reports. To do this, INS provides a set of symbols (nodes and branches)…
