HMMTree: A computer program for latent-class hierarchical multinomial processing tree modelsSpringer Science and Business Media LLC - Tập 39 - Trang 267-273 - 2007
Christoph Stahl, Karl Christoph Klauer
Latent-class hierarchical multinomial models are an important extension of the widely used family of multinomial processing tree models, in that they allow for testing the parameter homogeneity assumption and provide a framework for modeling parameter heterogeneity. In this article, the computer program HMMTree is introduced as a means of implementing latent-class hierarchical multinomial processing tree models. HMMTree computes parameter estimates, confidence intervals, and goodness-of-fit statistics for such models, as well as the Fisher information, expected category means and variances, and posterior probabilities for class membership. A brief guide to using the program is provided.
Sample-size determination for the Bayesian t test and Welch’s test using the approximate adjusted fractional Bayes factorSpringer Science and Business Media LLC - Tập 53 - Trang 139-152 - 2020

When two independent means μ1 and μ2 are compared, H0 : μ1 = μ2, H1 : μ1≠μ2, and H2 : μ1 > μ2 are the hypotheses of interest. This paper introduces the R package SSDbain, which can be used to determine the sample size needed to evaluate these hypotheses using the approximate adjusted fractional Bayes factor (AAFBF) implemented in the R package bain. Both the Bayesian t test and the Bayesian Welch’s test are available in this R package. The sample size required will be calculated such that the probability that the Bayes factor is larger than a threshold value is at least η if either the null or alternative hypothesis is true. Using the R package SSDbain and/or the tables provided in this paper, psychological researchers can easily determine the required sample size for their experiments.

AbstractIn recent years, cross-cultural research on the modulation of basic cognitive processes by culture has intensified – also from an aging perspective. Despite this increased research interest, only a few cross-culturally normed non-verbal stimulus sets are available to support cross-cultural cognitive research in younger and older adults. Here we present the ORCA (Official Rating of Complex Arrangements) picture database, which includes a total of 720 object–scene compositions sorted into 180 quadruples (e.g., two different helmets placed in two different deserts). Each quadruple contains visually and semantically matched pairs of objects and pairs of scenes with varying degrees of semantic fit between objects and scenes. A total of 95 younger and older German and Chinese adults rated every object–scene pair on object familiarity and semantic fit between object and scene. While the ratings were significantly correlated between cultures and age groups, small but significant culture and age differences emerged. Object familiarity was higher for older adults than younger adults and for German participants than for Chinese participants. Semantic fit was rated lower by German older adults and Chinese younger adults as compared to German younger adults and Chinese older adults. Due to the large number of stimuli, our database is particularly well suited for cognitive and neuroscientific research on cross-cultural and age-related differences in perception, attention, and memory.
Enhancement of adherence to tricyclic antidepressants by computerized supervisionSpringer Science and Business Media LLC - Tập 14 - Trang 176-180 - 1982

An on-line computer program to enhance drug adherence is described for individuals receiving tricyclic antidepressant treatment for depression. Because supervision is important in increasing adherence, a computer program was designed to provide this service and to intervene in particular adherence problem areas, such as comprehending the prescription, managing side effects, and altering negative cognitions about medications. An evaluation study of the pro-gram is presented.
The simultaneous and independent measurement of penile circumference and lengthSpringer Science and Business Media LLC - Tập 14 - Trang 447-450 - 1982
Christopher M. Earls, William L. Marshall
It has been recently shown that in the early stages of erection, the human penis undergoes a substantial length change that is not detected using circumferential measurement devices. The present report introduces a relatively simple device that can assess changes in both length and circumference. The device promises to provide a low-cost alternative to the precision and sensitivity associated with plethysmography.
An alphanumeric display program for a PDP-8Springer Science and Business Media LLC - Tập 3 - Trang 141-145 - 1971
Ralph Norman Haber
Alphanumeric and special characters composed of 5 by 7 dot matrices can be displayed on a cathode ray tube by use of a program written for the PDP-8 family of computers. The CRT surface is specified to contain up to 32 rows with up to 32 characters per row. The 35 dots defining each character require 1.5 msec to generate. Every possible arrangement of spatial and temporal organization among and between strings of characters can be created by simple parameter specification before each trial. The program is designed to operate with a minimal 4k-memory computer configuration, with no special hardware other than an oscilloscope display. The program also permits efficient on-line operation so that an entire experiment can be run quickly and efficiently without further programming. A large number of examples are detailed, and operating procedures are specified.
