The effect of additional variables on factor indeterminacy in models with a single common factor

Determinate solutions for the indeterminate common factor ofp variables satisfying the single common factor model are not unique. Therefore an infinite sequence of additional variables that conform jointly with the originalp variables to the original single common factor model does not determine a unique solution for the indeterminate factor of thep variables (although the solution is unique for the factor of the infinite sequence). Other infinite sequences may be found to determine different solutions for the factor of the originalp variables. The paper discusses a number of theorems about the effects of additional variables on factor indeterminacy in a model with a single common factor and draws conclusions from them for factor theory in general.     

An alternative to the methodology for analysis of covariance

A general statistical model for simultaneous analysis of data from several groups is described. The model is primarily designed to be used for the analysis of covariance. The model can handle any number of covariates and criterion variables, and any number of treatment groups. Treatment effects may be assessed when the treatment groups are not randomized. In addition, the model allows for measurement errors in the criterion variables as well as in the covariates. A wide variety of hypotheses concerning the parameters of the model can be tested by means of a large sample likelihood ratio test. In particular, the usual assumptions of ANCOVA may be tested.Research reported in this paper has been partly supported by the Swedish Council for Social Science Research under project Statistical methods for analysis of longitudinal data, project director Karl G.

Tests of symmetry in three-way contingency tables

Three-dimensional contingency tables are analyzed, with one variable (e.g., sex) as a factor, and with a natural relation between the other variables (e.g. left and right eye vision). Models of special interest, like symmetry and proportional symmetry between the related variables, and homogeneity across the factor levels, are investigated. Maximum likelihood estimators of parameters and partitions of chi-square goodness-of-fit statistics are explicitly presented; the independence of certain models is noted, and an example is discussed.     

A prospective study of the distribution of illness within the menstrual cycle

The cyclic physiological variations during the menstrual cycle are thought to be associated with change in emotional state, in susceptibility to illness, and in frequency of illness-related behavior. Variations in frequency of illness with the phases of the menstrual cycle were examined using data from a 3-year prospective study of social and psychological antecedents of viral illness in 94 student nurses. Reported illnesses, accidents, medical consultations, and hospital admissions were randomly distributed throughout the menstrual cycle. Subjects took more medication on the 1st day of menses than on any other day of the cycle; howeverreported menstrual symptoms were infrequent, with only 4% of the population reporting two or more such episodes. It was concluded that there was an increase in discomfort on the data of onset of menses which was self-medicated but not defined as illness. There was no discernible relationship of illness or disability to any phase of the cycle.This work was supported in part by Center for Oral Health Research (COHR) grant DEO 2116, and Oral Medicine Training Grant ST01-DE-77.

Affect and retrieval of personal memories

The relationship of pleasantness and intensity of affect to retrieval of reallife experiences was investigated in three experiments. Subjects reported the first specific personal experience that came to mind for a series of prompt words. Latency of report was regarded as a measure of memory accessibility. The first study compared retrieval time for prompts that sampled affects varying in pleasantness and intensity. Experiments II and III assessed the possible contributions of demand characteristics and implicit inferential processes to retrospective judgments of feelings. Judgments of the intensity of feeling engendered when the events occurred were inversely related to report latency. Results support the conclusion that intensity ratings were reliable indices of memory information rather than inferences or reconstructions mediated by report latency. Other characteristics of recollections such as pleasantness, recency, or relative frequency of the specific affects were not correlated with report latency. Two explanations of the findings are considered: an arousal hypothesis and an extent-of-processing hypothesis. The latter provides the most adequate account and relates the present findings to a more general theory of memory processes. The results are also relevant to investigations of mood-dependent retrieval.This is an expanded version of a paper presented in the Symposium on Naturally Occurring Memories, at the meeting of the American Psychological Association, Toronto, August 1978.     

The new experimental aesthetics—The beginning or the end?

In reference to recent work in aesthetics from a scientific perspective, Berlyne coined the phrase the new experimental aesthetics. Berlyne's contributions to this research area are discussed in terms of the philosophical, theoretical, and methodological issues central to the current literature. The paper concludes with a consideration of the future prospects for experimental aesthetics.This paper was presented at a symposium in honor of Daniel E. Berlyne at the annual meeting of the American Psychological Association, San Francisco, August 27, 1977. The presentation of this paper was supported by a grant from York University.     

The subjective vertical under ‘dry’ and ‘wet’ conditions at clockwise and counterclockwise changed positions and the effect of a parallel-lined background field

Summary The dependence of the subjective vertical (SV, the angle between a subjective vertical line and body median plane) on the gravity vertical (body tilt position, angle ) and on the optical vertical (i.e., a field of parallel lines seen as background to the line to be adjusted) was investigated. The SV was measured under dry and wet conditions at different degrees of body tilt attained in either clockwise (CW) or counterclockwise (CCW) progression.The measured difference in between field-of-lines left and right of the line is smallest at the upright position (=O°) and largest at =150°/165°. All body positions show a -difference between CW and CCW attainment (hysteresis), this too being least at upright and greatest at inverted body positions.These results, and changes of with test time, are discussed relative to the hypothesis that efficiency of the statolith organs decreases with body tilt increase, favouring increase of interference of somatoreceptors and the optical reference.
