very end of a music excerpt did not show effects on the subjective time estimation. But the
increase of the distance between origin and destiny keys elicits systematically smaller temporal
estimations, with major impact of sudden tonal modulations, as proposed in the Expected
Development Fraction Model (Firmino & Bueno, 2003).

Response regulation: From brain to behavior

5060.1 Neurodevelopmental aspects of response regulation, M.L. Smith, University of Toronto
at Mississauga, Mississauga, Canada
This presentation will address developmental aspects of response regulation, including a brief
review of the time-course of normal development and studies of impairments in response
regulation after early neurological insults. Two studies of response regulation in children with
intractable epilepsy will be described. In one, three aspects of response regulation, the ability to
self-pace, the ability to remain vigilant, and the ability to withhold responding until complete
information is available, will be examined within a sustained attention paradigm. The second
study will examine response regulation and other executive functions as manifest in the everyday
lives of children with seizure foci in the frontal lobes.

Age-related differences in response regulation were studied with functional magnetic resonance
imaging. Twenty-six subjects belonging to two groups, specifically a younger group and a
middle-aged group (the mean ages of which were 22.62 and 47.68 years respectively), were
administered an experimental task measuring response regulation. The imaging data indicated that
frontal activation was more bilaterally represented in younger subjects, compared with the
middle-aged subjects, when performing the same experimental task of response regulation. The
findings suggested that there seemed to be age-related differences in neural activation associated
with response regulation between the middle-aged and younger adults.

Inhibition is considered a key mechanism serving the control and regulation of goal-oriented
behaviors. Cognitive studies of inhibition have been closely associated with attention, selection of
information from objects in the perceptual world and selection among representations within
working memory. In this paper, I will describe the different ways researchers have used to
conceptualize inhibition, arising from different fields of cognitive psychology. Evidence with
imaging research methods will also be presented to review what we have learned about the neural
