AIMS To provide normative data for chromatic discrimination on the Farnsworth-Munsell 100 hue test particularly for observers under 23 years of age. METHODS Normal observers were screened for congenital colour vision deficiencies using the Ishihara test leaving 382 observers. RESULTS New total error score (TES) norms (means and 95th percentiles) are presented for each year of age from 5-22 ...

Our goal is to use formal methods to analyse normative documents written in English, such as privacy policies and service-level agreements. This requires the combination of a number of different elements, including information extraction from natural language, formal languages for model representation, and an interface for property specification and verification. We have worked on a collection ...

The Monty Hall Dilemma (MHD) is a striking example of the human tendency to base probability judgment on intuitive, erroneous heuristics instead of an analytic, normative reasoning process. Two experiments tested the claim (e.g., Stanovich & West, 2000) that correct, normative reasoning draws on executive, working memory resources (WM) whereas heuristic reasoning would be purely automatic. Expe...

We consider the problem of updating a multi-agent system with a set of conditional norms. A norm comes into effect when its condition becomes true, and imposes either an obligation or a prohibition on an agent which remains in force until a state satisfying a deadline condition is reached. If the norm is violated, a sanction is imposed on the agent. We define a notion of a normative update of a...

This study examines influence and IT in group polarization. Group polarization is the tendency of group members to shift their initial positions to a more extreme direction following discussion. We hypothesize that informational influence is relatively more important than normative influence in causing group members to shift their positions and that IT can be used to enhance the effects of info...

People taking part in argumentativedebates through collective annotations face a highly cognitive taskwhen trying to estimate the group’s global opinion. In order to reduce this effort, we propose in this paper to model such debates prior to evaluating their “social validation.” Computing the degree of global confirmation (resp. refutation) enables the identification of consensual (resp. contro...

This article identifies four factors for consideration in norms-based research to enhance the predictive ability of theoretical models. First, it makes the distinction between perceived and collective norms and between descriptive and injunctive norms. Second, the article addresses the role of important moderators in the relationship between descriptive norms and behaviors, including outcome ex...

Consent to perform a small favor increases a respondent's susceptibility to perform a relatively large favor. This phenomenon, known as the foot-in-the-door effect, is considered to result from induced self-perception changes: the respondent comes to feel helpful for doing the small favor and complies again later out of a desire to maintain the instilled self-view. This study did not find a lin...

Introduction Giles has proposed Speech Accommodation Theory (SAT) to account for language usage between individuals (see e.g. Giles et al., 1977). That theory is concerned with determining what motivates an individual to de-accentuate ethnolinguistic characteristics and converge toward the dominant culture, or to accentuate his/her ethnolinguistic characteristics and diverge from the dominant p...
