TCN_BM.EXE (40,496 bytes)	"Neuropsychology and Neurosciences Resources on the Web" in HTML format. by Kim Kerns Self-extracting ZIP file.
NPSTAT.ZIP (468,518 bytes)	Companion program for "Application of Statistics in Behavioral Research" text by May, Masson, & Hunter (1990, Harper & Row)
CPCA.ZIP (65,231 bytes)	A program for "Constrained Principle Components Analysis" by Hunter & Takane
MSDA_2A.ZIP (80,026 bytes)	A program for "Multi-dimensional Signal Detection Analyses" (Version 2.1, May 2000) by Helena Kadlec MSDA_2A.ZIP -- replaces MSDA_2.ZIP. This is version 2.1 of MSDA, and it is identical to version 2.0 (in MSDA_2) but includes a correction to the Z-test for testing Ho: two d' estimates are equivalent. This error affected inferential tests for perceptual separability (PS): No other inferential tests were affected. MSDA_2 is an updated version of the program MSDA (version 1, originally posted in 1996) that uses a multidimensional version of signal detection theory to analyze symmetric confusion matrices for perceptual and decisional separabilities and perceptual independence, as defined within the General Recognition Theory (see Ashby & Townsend (1986), "Varieties of independence", Psychological Review, vol. 93, pp. 154-179.) More detailed information about the original version of the program can be obtained from Kadlec, H. (1995). Multidimensional signal detection analyses (MSDA) for testing separability and independence: A Pascal program. Behavior Research Methods, Instruments, & Computers, vol. 27, pp. 442-458. CHANGES for version 2.0 are documented in the accompanying <changes2.txt> file; for more technical information see Kadlec, H. (1999). MSDA_2: Updated version of software for Multidimensional Signal Detection Analyses. Behavior Research Methods, Instruments, & Computers, vol. 31, pp. 384-385.
POWER1.ZIP (37,633 bytes)	A program for "Statistical Power" by Helena Kadlec This program is a short tutorial on statistical power, the probability of correctly rejecting a null hypothesis. It is intended as a teaching tool for an introductory statistics course, either as a classroom demonstration or as a take-home tutorial. It shows how four factors (sample size, alpha, standard deviation, and the alternative mean) affect the degree of power in the one-sample z-test. A short workbook (12 pp.) is enclosed in two versions: - WORKBOOK.WPW is a WordPerfect (version 5.2 for Windows) file. - WORKBOOK.TXT is a plain ASCII file. The WordPerfect version is intended and formatted for printing. The workbook includes step-by-step instructions on how to use the program (first 3 pages), sample questions to explore each factor (pp. 4 - 7), general practice questions (p. 8), and an answer key to all questions in the workbook (pp. 9-12).
TIMING.ZIP (83,972 bytes)	This is a millisecond timing subroutine with QuickBasic 4.5 libraries and demonstration programs as described in; Graves, R.E. & Bradley, R. (1991). Millisecond Timing on the IBM PC/XT/AT and PS2: A review of the options and corrections for the Graves and Bradley Algorithm, Behavior Research Methods, Instruments, and Computers, 23, 377-379.
SB16DL.ZIP (168,202 bytes)	This contains dichotic listening subroutines and demonstration programs for recording and dichotic playback using the Sound Blaster 16 board. These programs are described in: Graves, R.E., and Allen, T. (1996). Utilizing the Sound Blaster 16 Board for Dichotic Listening Studies, Behavior Research Methods, Instruments, and Computers, 28, 468-469.
