REFERENCE: An APPLE II package for storage and retrieval of journal references

The package described here enables the user to maintain a “card index system” of journal references on floppy disk, with easy retrieval of references by author, subject, or combination of subjects.     

A FORTRAN program for lag sequential analysis of contingency and cyclicity in behavioral interaction data

One method for identifying contingency relationships in a sequence of observed behaviors studies occurrences of matching behaviors at successive event or time steps from a criterion event. This paper briefly summarizes the method and presents a computer program for generating lag conditional probabilities and associated measures for assessing statistical significance.     

Normative data for number of word meanings

A corpus of 576 words and orthographically legal pseudowords was rated by 150 undergraduates to obtain a subjective estimate of the number of meanings possessed by the stimuli. The information contained in this corpus may be used to supplement current, sources of word-meaning information (e.g., total number of dictionary entries). Experimental evidence is presented that supports the reliability of the normative data.     

TREBIG: A 360/75 FORTRAN program for three-mode factor analysts designed for big data sets

In the analysis of multifactor, longitudinal data, it has long been the practice of investigators to factor analyze the data in each time period separately and then compare the factor structures by eye. This has obvious problems and various measures of similarity were devised, none of which really worked properly. In recent years, other procedures have been proposed to better handle these sorts of data (i.e., Corballis, 1970; Jöreskog, 1970; Tucker, 1966). Tucker’s solution is termed “3-mode factor analysis,” which is essentially the Eckart-Young decomposition of a set of matrices that are derived by collapsing a tensor of order three. It has the advantage of combining the factor analyzes of each time period and indicating how the changes occur.
