摘要:Professionals are used to developing a specific language at work, an operational form ofcommunication particularly reinforced in high risk industries (e.g. energy industries, aircraftcompanies, hospitals). This is favored by a high level of technicality of the context thatusually provides the roots of this language. Although a psycholinguistic approach may helppeople to assess whether this kind of standard usage of communication is reliable enough, notto lead to a mistake that may give rise to undesirable events (such as deviation from theexpected results), the literature is void of such studies.Simulated and real operational working situations were observed over two yearsinvolving French nuclear reactor operators. Analyses were undertaken from psycholinguisticand socio-psychological standpoints based on observations, video-recordings and interviews.Analysis has established the process of elaboration of the standard usage of communication.We showed that the operators’ self-assessment was positive regarding the reliability of thisway of communicating, but the analysis pointed out weaknesses: in some communicationcontexts characterized by replacements in a team or discussions between two differentprofessions, the level of reliability could seriously decline, hence favoring mistakes. Theseresults led us to conclude that the established standard usage of communication could nolonger be used.
