Abstract

Law and Information are two concepts that need each other, although the complexity of their relationship is not always fully understood. We propose an overview of the main areas where this relationship is more intimate and fundamental. To make this overview more comprehensive we will focus on the three functions that Law can exercise over Information: hide, preserve and share. All topics discussed are highly related and the discussion of one has to take into account the other. The good news is that Law has been responding to the needs of the society due to the challenges posed by technological and social changes for millenia and it has the tools to do it again. For this, legal practitioners need the support of information professionals to guide them through all the new phenomena arising from digital information.

Abstract

International audience; The aim of the present contribution is to test whether and to what extent cognitive load theory may account for working memory performance in the field of ergonomics. We will briefly present the theoretical and methodological principles of cognitive load theory, developed initially by Sweller (1988) in the field of educational psychology, and some of the more critical issues addressed recently. Thereafter, we report three experiments exploring the relations between the three load categories defined by cognitive load theory, by using working memory tasks. The influence of intrinsic and extrinsic cognitive load categories was explored by manipulating respectively task difficulty and time pressure. The consequences of the less documented germane load were proposed to depend on participants’ alertness that varies spontaneously across the day (Galy, Cariou, and Mélan, 2012). In order to test for additive effects between load categories, effects of intrinsic and extrinsic load were explored both separately and simultaneously, and when participants’ alertness level was either high or low. This procedure was tested in a mental arithmetic task and in a recall task performed by participants in controlled laboratory conditions and when the same arithmetic task was performed by air traffic controllers in a real-job situation. Results led to the conclusion of an additive interaction between intrinsic and extraneous cognitive load factors, in addition to modulatory effects by germane load.
