Zusammenfassung: | Recently, a lot of research has focused on resolving whether two-digit numbers
are processed holistically or compositionally. This has led to inconsistent
results. In the present study we investigated effects of task instructions.
Subjects performed magnitude or parity judgments on targets preceded by masked
primes containing parts of the target at a task-congruent (3#_37) or
task-incongruent (#3_37) position. Priming effects were influenced by
the instructions: In the magnitude task, the priming effects were primarily
mediated by the congruency of the decade digit, whereas in the parity task they
were elicited by the congruency of the unit digit, which is in line with a
flexible compositional processing style. These and previous findings show that
two-digit numbers can be processed in a very flexible way, depending on the task
context. |
