摘要:

Methods are described for transforming factors in such a way that the final loadings are in reasonable conformity with a givenpatternin which some of the elements are postulated to be zero. A distinction is made between factors which, in their transformed state, are (i) correlated and (ii) uncorrelated. The methods are illustrated by numerical examples.

摘要:

In the following paper an attempt is made to derive a working formula, based on the method of maximum likelihood, for testing the significance of the difference between two reliability coefficients. It is assumed that both tests have been administered to the same group, and can be split into equivalent halves. A worked example is appended by way of illustration.

摘要:

This paper examines Stroud's theory that the perceptual input is quantized in time (the perceptual moment hypothesis). A model of the detection of change based on the theory is compared with other models derived from statistical quality control methods; in particular those using simple and geometric moving averages. They are compared theoretically to see which entails the least computational load for the brain. Empirical comparisons are made with data from loudness thresholds, brightness thresholds, and the perception of causality: all cases in which there is little change in stimulus intensity. The perceptual moment hypothesis is found to be the most satisfactory. Finally, some of the assumptions of the perceptual moment model are examined in more detail and the model is extended to deal with situations in which the intensity of stimulation alters greatly.

摘要:

Taste assessment procedures are examples of human sensory and hedonic judgements which have not generally been analysed in dynamic psychophysical terms, though an extensive statistical literature has grown up to cover the use of such procedures. A taste comparison procedure, using mixtures of wines as stimuli and 168 non‐expert subjects as tasters, yielded data on five response measures which have been analysed using a linear trace decay model. The fit of the model is good and accounts for most of the observed variation in assessed differences which is associated with orders of tasting samples. Reasons for a poor fit in a minority of cases are discusse

摘要:

The paper discusses the hierarchical conception of factorial structure developed by Burt and his research students, and examines the alternative approaches preferred by Thurstone and Cattell. It is argued that second‐order factors cannot be distinguished from first‐order factors by mathematical criteria. It follows that interpretational criteria are requisite and the method of transformation described by Schmid and Leiman is recommen

摘要:

A more comprehensive scheme for classifying theoretical concepts is needed to clarify the issues involved in choosing concepts for psychology. The scheme here proposed concentrates on distinctions of observational and ontological status which seem basic to such issues. Psychology can best advance as a science through a more liberal acceptance of various types of concepts whose use is at present too often rejected, notably concepts embodying existential hypotheses, or designating so‐called ‘private’ phenomena of consciou
