validity. We present results on temporal-order judgment showing group differences in performance
(men vs. women, young vs. elderly person, aphasics vs. controls) that depend on the stimulation
parameters and the reliability of the method. The association of temporal-processing and phoneme
discrimination in patients with aphasia varies depending on the assessment method employed.

Inhibition of return (IOR) refers to a slowed response time for targets appearing at a previously
cued location. The present study examined the age-related differences on the time course of IOR
with a discrimination task in 48 young and elderly adults. Intervals between peripheral cues and
targets were systematically varied from 400 ms to 2100 ms with a typical double cue procedure.
Results show that elderly adults exhibit both a later onset and an earlier offset of IOR as compared
to young adults. Possible reasons underlying the different time course of IOR for the two age
groups were discussed.

Neuropsychological evidence suggests an association between temporal information processing
(TIP) and cognition. At least three different ranges of around 30, 300 and 3000 milliseconds seem
to be crucial for human behaviour, including language functions. In a series of experiments we
studied TIP on the above time domains in young healthy volunteers, elderly people, centenarians
and subjects with language disorders of different etiologies: congenital deafness, cochlear
implantation, autism, aphasia. We found associations between atypical TIP and chronological
ageing or language deficits. We conclude that in many cognitive processes timing is of an essence.
2005 INVITED SYMPOSIUM
Recent developments in working memory
Convener and Chair: A. Baddeley, UK
2005.1 Child development as a portal to working memory processes, N. Cowan, University of
Missouri, Columbia, MO, USA
This talk will focus on two questions about the development of working memory: why it is worth
studying and what methods might help in studying it. Basically, it is worth studying because the
history of the child’s working memory helps to explain the processes of the adult mind, much as
the history of a nation helps to explain its present political form. When studying a theoretical
concept such as working memory and trying to pinpoint its mental mechanisms, one must be
particularly concerned with psychological measurement issues. Some methodological suggestions
will be offered with respect to two basic parameters of working memory: its speed and its
capacity.
