A new method for analyzing aesthetic preferences: Some theoretical considerations

The aesthetic preferences of a group of persons are obtained from their orders of sets of pictures and patterns according to “liking.” The same pictures are ordered independently by a team of experts, according to certain artistic criteria such as naturalism, composition, color, rhythm, etc. The orders of preference and orders according to the criteria are compared by correlation and matrices of correlation formed from (1) correlations between the persons' orders of preference; (2) correlations between the orders of preference and orders according to artistic criteria; and (3) correlations between the criterion orders. These matrices are symbolised byR _p ,R ₀, andR _c , respectively, and combined to form a single matrix

A method for analyzing changes in response efficiency.

Although experimental effects typically are evaluated by summarizing levels of responding across time (e.g., calculating the mean levels of problem behavior during 10‐min sessions), these data summaries may obscure important mechanisms that may be responsible for changes in responding. A case study is reported to illustrate alternative methods of data analysis when decreasing trends in responding may be due to increases in response efficiency.     

A practical method for analyzing factorial designs with heteroscedastic data

The Type I error rates and powers of three recent tests for analyzing nonorthogonal factorial designs under departures from the assumptions of homogeneity and normality were evaluated using Monte Carlo simulation. Specifically, this work compared the performance of the modified Brown-Forsythe procedure, the generalization of Box's method proposed by Brunner, Dette, and Munk, and the mixed-model procedure adjusted by the Kenward-Roger solution available in the SAS statistical package. With regard to robustness, the three approaches adequately controlled Type I error when the data were generated from symmetric distributions; however, this study's results indicate that, when the data were extracted from asymmetric distributions, the modified Brown-Forsythe approach controlled the Type I error slightly better than the other procedures. With regard to sensitivity, the higher power rates were obtained when the analyses were done with the MIXED procedure of the SAS program. Furthermore, results also identified that, when the data were generated from symmetric distributions, little power was sacrificed by using the generalization of Box's method in place of the modified Brown-Forsythe procedure.     

A basis for analyzing test-retest reliability

Three sources of variation in experimental results for a test are distinguished: trials, persons, and items. Unreliability is defined only in terms of variation over trials. This definition leads to a more complete analysis than does the conventional one; Spearman's contention is verified that the conventional approach—which was formulated by Yule—introduces unnecessary hypotheses. It is emphasized that at least two trials are necessary to estimate the reliability coefficient. This paper is devoted largely to developinglower bounds to the reliability coefficient that can be computed from but asingle trial; these avoid the experimental difficulties of making two independent trials. Six different lower bounds are established, appropriate for different situations. Some of the bounds are easier to compute than are conventional formulas, and all the bounds assume less than do conventional formulas. The terminology used is that of psychological and sociological testing, but the discussion actually provides a general analysis of the reliability of the sum ofn variables.The writer is indebted to the members of his statistical seminar, to Professor Mark Kac, and to Professor Samuel A. Stouffer and his staff in the Research Branch, Information and Education Division, War Department, for their helpful comments on this paper.     

A computerized method of analyzing and playing back vibratory animal signals

In water striders or other animals that communicate with vibratory or oscillatory signals, surface wave signals can be recorded, analyzed in digital form by computer, then played back accurately by oscillating a magnet, glued to the animal, with electromagnetic fluctuations from a coil driven by the computer. Signals can be played with great flexibility through a normally behaving animal, in laboratory or field.     

A computerized system for analyzing linear locomotion

An accurate and reliable, yet simple and inexpensive electronic tracking device delivers voltages that denote changing positions of moving objects. In combination with an analog-to-digital converter, a microcomputer, and specific software, this device enables the depiction and analysia of linear or linearly represented locomotion. The system is particularly useful for laboratory analysis of animal movements. An application in preference-avoidance testing is described.     

Dialectic Dialogue: A new method for inter-religious dialogue

Presented in this article is a new method for dialogue between faith traditions. The proposed new method is presented in the form of a theoretical dialogue between Jews and Christians concerning 'salvation'. It is set forth as a 'dialectic dialogue' that shifts the focus from a direct comparison of the traditions to an indirect one. The indirect elements used are three dichotomies experienced by all and how the two traditions' adherents are encouraged to understand them is the object of discussion. This dialogue, which compares how the two traditions teach their adherents to frame these dichotomies, avoids the problems that often bring inter-religious dialogues to a premature end.     

Varisim: A new machine method for orthogonal rotation

The derivative of Kaiser's Varimax criterion, if set to zero, yields a set of equations which are quite similar to those obtained for a least-squares problem of the Procrustes type. This similarity suggested an iterative technique for orthogonal rotation, dubbed Varisim, which was programmed for the IBM 7094 in FORTRAN. An empirical comparison between Varimax and Varisim, which was based on a number of data sets taken from the literature yielded three major results so far: (i) Varisim is slower than Varimax, roughly by a factor of 3, (ii) Varisim yields factors which in general contribute more evenly to the common test variance than Varimax factors, and which (iii) line up more closely with oblique configurations obtained with Binormamin than Varimax factors.This paper is based on parts of a thesis submitted to the Graduate College of the University of Illinois in partial fulfillment of the requirements for a degree in Psychology. Some of its contents were read at the joint meeting of the Psychonomic and the Psychometric Society, Niagara Falls, Ontario, 1964. Most of the computer-bound work was carried out while the author was employed by the Statistical Service Unit, University of Illinois; it was written up while the author held a Postdoctoral Fellowship at the Psychometric Laboratory of the University of North Carolina. Although space limitations forbid more complete acknowledgments, I am bound to record my deep gratitude to my advisor, Prof. H. F. Kaiser.

A new method for automated reconstruction of pre-transformation microstructures

A new method, referred to as the cluster method, is proposed and tested for the reconstruction of pre-transformation microstructure in Ti–6Al–4V alloy. The cluster method begins by constructing clusters of daughter grains (room-temperature hcp α-phase) that have a high probability of being transformed from the same parent grain (high-temperature bcc β-phase). These clusters are then grown, and back-transformed to the parent grain orientations using the ‘summation of mutual misorientation angle method’ (SMMA method). The cluster method is validated by comparing the obtained results with the results of the SMMA and triplet methods.     

A technique for quantifying and analyzing evoked responses

Two computer programs are discussed. One is used in the analog-to-digital conversion of and averaging of the responses; the other employs fuil-wave rectification and numerical integration as a method of comparing waveforms.
