Dimensionality of the perceived self: the Tennessee Self Concept Scale.

The 12 indices of self-perception in the Tennessee Self Concept Scale, together with the Eysenck Personality Inventory, were factor analysed using data obtained from psychiatric day-care patients (n = 131). Separate item- and scale-level factor analyses revealed that: (1) the five external and three internal domains of self-concept, hypothesized as distinct, may be accurately viewed as lying in one-dimensional space; (2) the conflict, variability and distribution scores are unrelated to subtype of self-esteem; (3) extraversion and neuroticism form a bipolar factor that is orthogonal to self-concept; and (4) the emergence of 30 item-factors with a 30 per cent factorial overlap implies a good deal of spuriously shared variance, low inter-scale homogeneity and sizable redundancy in the TSCS scales. Owing to these results, the construct and factorial validity of the TSCS is seriously questioned. It is suggested that future researchers develop more sensitive, treatment-oriented (or idiographic) measures to compare man's less conspicuous and more private 'self-image feelings and cognitions' against his public self-disclosure in the interests of facilitating more rapid behavioural change.

Absolute pitch: a case study.

The auditory skill known as 'absolute pitch' is discussed, and it is shown that this differs greatly in accuracy of identification or reproduction of musical tones from ordinary discrimination of 'tonal height' which is to some extent trainable. The present writer possessed absolute pitch for almost any tone or chord over the normal musical range, from about the age of 17 to 52. He then started to hear all music one semitone too high, and now at the age of 71 it is heard a full tone above the true pitch. Tests were carried out under controlled conditions, in which 68 to 95 per cent of notes were identified as one semitone or one tone higher than they should be. Changes with ageing seem more likely to occur in the elasticity of the basilar membrane mechanisms than in the long-term memory which is used for aural analysis of complex sounds. Thus this experience supports the view that some resolution of complex sounds takes place at the peripheral sense organ, and this provides information which can be incorrect, for interpretation by the cortical centres.
