Abstract
Forty Ss were given a serial-learning task involving 10 three-place numbers. The sixth item either had similar digit composition or was isolated by having a different digit composition. A strong and stable isolation effect was observed. The isolation effect was interpreted as being due to a lesser degree of formal similarity, and its stability to the absence of spread of isolation effect.
