The present article is a case study in which participation is investigated in terms of the use of interactional practices that enhance the involvement of a man with severe aphasia in activities that aim to capture his and his wife's experiences of everyday communication, and their views of his speech and language intervention. Five practices are identified: 1) collaborative telling, 2) formulat...

A psychometric function describes the relation between some physical measure of a stimulus and the probability of a particular psychophysical response. The physical measure is usually stimulus strength, and the response is "yes" (in a yes/no experiment) or "correct" (in a forced-choice experiment). More generally, there are several possible responses, each with its own psychometric function (e....

Delayed matching to sample is typically a two-alternative forced-choice procedure with two sample stimuli. In this task the effects of varying the probability of reinforcers for correct choices and the resulting receiver operating characteristic are symmetrical. A version of the task where a sample is present on some trials and absent on others is analogous to a yes/no recognition task. We desc...

We investigated whether and how sublexical units such as phonological syllables mediate access to the lexicon in French visual word recognition. To do so, two lexical decision task (LDT) experiments examined the nature of the syllabic neighbourhood effect. In Experiments 1a and b, the number of higher frequency syllabic neighbours was manipulated while controlling for the first bigram. The resu...

A longstanding puzzle in the semantics/pragmatics of questions has been the subtle differences between positive (e.g. Is it . . . ? ), low negative (Is it not . . . ? ), and high negative polar questions (Isn’t it . . . ? ). While they are intuitively ways of asking “the same question”, each has distinct felicity conditions and gives rise to different inferences about the speaker’s attitude tow...

In an associative recognition task, distractors generally consist of a rearrangement of the items composing the study pairs. This makes it possible that processing the distractors generates retroactive interference on memory for the study pairs. In Experiment 1, we explored this possibility in a yes/no recognition test concerning previously learned arbitrary associations between visual symbols ...

OBJECTIVES To evaluate the format, content, and effectiveness of a newly developed orientation to wellness workshop, and to explore participants' overall perceptions. METHODS This was a mixed methods study. Participants consisted of 47 new faculty of medicine members who attended one of the four workshops held between 2011 and 2013. Questionnaires were used to evaluate workshop characteristic...

INTRODUCTION Older adults' perception of their own risk of fall has never been included into screening tools. The goal of this study was to evaluate the predictive validity of questions on subjects' self-perception of their own risk of fall. METHODS This prospective study was conducted on a probabilistic sample of 772 Spanish community-dwelling older adults, who were followed-up for a one yea...

According to Crain and Nakayama (1987), when forming complex yes/no questions, children do not make errors such as Is the boy who smoking is crazy? because they have innate knowledge of structure dependence and so will not move the auxiliary from the relative clause. However, simple recurrent networks are also able to avoid such errors, on the basis of surface distributional properties of the i...
