"Cryptomnesia" means that, despite selectivity and social resistance to innovation, minority views can induce transformations in perceptions, without being credited with having done so. The proposed analytic model calls for three sets of notions. 1. Accounting for such phenomena as discrimination against - and open resistance to - minority views, the process of social comparison derives its impetus from a dynamics of identity. 2. Accounting for latent normative transformations, the process of validation derives its impetus from a sociocognitive dynamics of a constructivist type... 3. Connecting social comparison and validation, the notion of dissociation, implies that, when latent, the influence exerted by a minority - here defined as conversion - relies on a sociocognitive process which is not only majority-centered, but minority-centered as well. This process takes place in a multidimensional rather than unidimensional universe of judgments. On propose une explication psychologique du phénomène de cryptomnésie sociale, selon lequel au-delà des discriminations et des résistances sociales à l'innovation, les points de vue minoritaires concèdent un évident impact social, sans que le changement ne leur soit imputé. Le modèle proposé suppose trois ensembles de notions : le processus de comparaison sociale rend compte des phénomènes de discrimination et de résistances ouvertes aux minorités, et repose sur des dynamiques de nature identitaire; le processus de validation rend compte des changements normatifs latents, et implique des dynamiques sociocognitives de nature constructiviste ; finalement, la notion de dissociation permet l'articulation de ces deux processus, et stipule que l'impact minoritaire latent, qualifié de conversion, présuppose un fonctionnement sociocognitif non pas seulement majocentrique, mais aussi minocentré, prenant place dans un univers de jugements plutôt multidimensionnel qu'unidimensionnel.

One application is an annotation tool, the second one replicates a modelling system on the PDA and the third one makes use of a wireless optical reader in addition to the PDA. They all provide ‘lightweight’ synchronisation mechanisms in PC-based environments. General design and implementation strategies for such extensions are discussed in terms of model, view and controller.
