In self-paced auditory memory span tasks, the microanalysis of
response timing measures represents a developmentally sensitive
measure, providing insights into the development of distinct processing
rates during recall performance. The current study first
examined the effects of age and trait anxiety on span accuracy
(effectiveness) and response timing (efficiency) measures from
word and digit span performance in a preschool sample (N = 76,
mean age = 57 months, SD = 11). Children were reassessed 8
months later using the same two tasks plus a test of nonword
memory span and a measure of articulation rate. The results at
the second time point (T2) confirmed the effects of age on both
processing effectiveness and efficiency. Trait anxiety was an additional
negative predictor of span effectiveness (especially for digit
span) and efficiency (in the case of word and nonword span). The
findings are discussed in the context of factors contributing to early
short-term memory development and attentional control theory.
