Abstrakt: A study was undertaken to determine how well a small sample of British male and female subjects could discriminate between a standard seat set at a height of 43·18 cm and a comparison seat, the height of which was varied in 0·64 cm stops between 40·64 and 45·72 cm. The Method of Constant Stimuli was used to present the seats to the subjects. A Differential Threshold and the Point of Subjective Equality were calculated for each subject, on whom stature and lower leg measurements wore taken. The main results were (a) the mean Differential Limen for males was 0-84 cm, for females 0-64 cm. There was no significant difference between these means; (b) the mean Point of Subjective Equality for males was 43-08 cm, that for females 4305 cm. There was no significant difference between these means; (c) no relation was found between the Differential Limen and Point of Subjective Equality, nor between those measures and the anthropometric dimensions. The main conclusion from this study is that individuals discriminate between seat heights extremely well. This has important implications for the designer and manufacturer of chairs [ABSTRACT FROM PUBLISHER]
