Abstract
Summary : Is the left hemisphere of the human brain move time-dependent than the right ? The particular relationship between the functioning of the left hemisphere (LH) and time is well known for two aspects : the suspected davantage of the LH over the right in tasks of perception of time and the importance of time in theoretical descriptions of LH specialization (the LH is described as analytical, serial, sequential, etc.). The present review emphasizes a third form of relationship. It is suggested that the LH needs time to develop an optimal efficiency of performance. Empirical arguments are found in three areas. First, on a microgenetic level, it appears that performance of the LH increases with stimulus exposure duration, even within the limits of the tachistoscopic durations used in neuropsychology (from about 10 to 250 ms). Second, there is reason to think that the efficiency of the LH increases from the beginning to the end of an experiment or experimental session. Finally, it seems that the LH is particularly able to process material for which the subject has been familiarized, over a long period of time. Key words : left hemisphere, time.
