This research aims to analyse how drivers integrate the information provided by traffic signs with their general goals (i.e. where they want to go). Some previous studies have evaluated the comparative advantages of obligatory and prohibitory traffic signs using a judgement task. In this work, a new experimental task with greater similarity to driving(More)
Using a priming paradigm in the context of a reading comprehension task, the possibilities that people keep in mind in order to understand indicative and subjunctive concessive sentences were examined and compared to those from factual and counterfactual 'if A, not-B' conditionals. The length of time it took people to read conjunctive descriptions (i.e., A(More)
Considerable research efforts are currently being devoted to analysing the role that the attentional system plays in determining driving behaviour, with the ultimate objective of reducing the number of attention-related accidents. The present study aims to assess the influence of differences in the functioning of the three attentional networks (executive(More)
We report the results of two experiments investigating conditional inferences from conditional unless assertions, such as Juan is not in León unless Nuria is in Madrid. Experiments 1 and 2 check Fillenbaum's hypothesis about the semantic similarity of unless with if not and only if assertions; both also examine inferential endorsements (Experiment 1) and(More)
We report the results of an experiment investigating conditional inferences from conditional assertions such as 'Juan won't go to León unless Nuria goes to Madrid' and 'Either Nuria goes to Madrid or Juan won't go to León'. This experiment addresses Dancygier's claims about the semantics of 'unless' by examining inferential endorsements of 'not-A unless B'(More)
The mental model theory assumes that people reason by manipulating mental representations of states of the word, called "mental models." In the present study we used a new deduction task based on diagrammatic premises. We show that a premise can prime other premises that induce similar mental models in a way analogous to the case of words with related(More)
We report three experiments on semifactual conditionals such as 'even if he had worn his seatbelt he would have been injured'. Semifactuals contain a counterfactual antecedent (the presupposed fact is, he did not wear a seatbelt) and a true consequent (the fact is, he was injured). The experiments show that from the denial of the antecedent, 'he did not(More)
Every traffic sign conveys a single proposition about traffic conditions. Drivers must integrate this proposition with their goals and other known facts to decide on an appropriate action in what amounts to a deduction task. For example, imagine that you are driving a car and you want to turn right at an intersection but there is a 'no right turn' sign. You(More)
Previous studies in spatial propositional reasoning showed that adults use a particular strategy for making representations and inferences from indeterminate descriptions (those consistent with different alternatives). They do not initially represent all the alternatives, but construct a unified mental representation that includes a kind of mental footnote.(More)
The present research evaluates how people integrate factual 'if then' and semifactual 'even if' conditional premises in an inference task. The theory of mental models establishes that semifactual statements are represented by two mental models with different epistemic status: 'A & B' is conjectured and 'not-A & B' is presupposed. However, following the(More)
