Auditory attentional blink: masking the second target is necessary, delayed masking is sufficient.

When two target items (T1 and T2) are presented in rapid succession among fillers, processing T2 is often impaired. This phenomenon is known as the attentional blink (AB). Within the visual modality, this second-target deficit generally occurs only if T2 is masked by a trailing item. The current study was designed to examine whether masking of T2 also plays a critical role in the auditory AB. Results showed a reliable AB effect even when the item following T2 was replaced by silence. However, the AB deficit was abolished when T2 was the last presented stimulus. Our results suggest that, as in vision, T2 masking is necessary for the AB to take place in audition, but that masking is effective even when delayed, providing evidence that the phenomenon shares some functional mechanisms across sensory modalities.     

Mismatch of vocational graduates: What penalty on French labour market?

This study explores individual effects of educational mismatch on wages, job satisfaction and on-the-job-search on French labour market. We distinguish between horizontal matches (job matches with field of studies) and vertical matches (job matches the level of qualification) on the one hand and skills matches (worker's assessment) on the other hand. We use data from the French survey “Generation 98,” conducted among a sample of 22780 young vocational graduates asked about their employment situation 3 years after leaving school. We show that whatever the criterion chosen, there is a minority of matched situations. We find that situations of vertical mismatch and skill mismatch have strong negative effects on wages, while situations of horizontal mismatch have not. However, horizontal mismatch increases both job dissatisfaction and the desire to find another job, even if their job is qualified, permanent and reasonably well paid. Implications for the evaluation of vocational training programs are discussed.     

Évolutions récentes de la responsabilité pour défaut d’information

It is wrongly that one would think that the question of the information due by the physician to the patient is not likely of any further developments. Four recent rulings provide the perfect illustration and lead to consider that this duty to inform has attained a genuine autonomy. In some instances, the compensation arising out of the failure to inform may depart from the strict framework of loss of chance in which many believed it was confined to.     

When does between-sequence phonological similarity promote irrelevant sound disruption?

Typically, the phonological similarity between to-be-recalled items and TBI auditory stimuli has no impact if recall in serial order is required. However, in the present study, the authors have shown that the free recall, but not serial recall, of lists of phonologically related to-be-remembered items was disrupted by an irrelevant sound stream (end rhymes) sharing similar phonological content. These findings can be explained by the notion that between-sequence phonological similarity effects emerge when category-cueing processes become an important determinant for recall, such as when shared category information can be used as a retrieval aid to cue list items or plausible list candidates. In this case, the presence of categorically similar irrelevant items impairs the retrieval of list items and leads to intrusion error. Implications of these results for theories of auditory distraction are discussed.     

Utilitarian relevance and face management in the interpretation of ambiguous question/request statements

Often, requests are made in an indirect manner and phrased in such a way that they can also be construed as questions. For example, the sentence “Is there any coffee left?” can be construed either as a question about coffee or as a request for coffee. This article offers a combined test of some key predictions of two approaches to the disambiguation of question/request statements: (1) the face management approach, which gives a prominent role to variables such as status and potential loss of face; and (2) the utilitarian relevance approach, which gives a prominent role to the goals pursued by the speaker at the time he or she issues the statement. Ambiguous question/request statements provide a natural test bed for the latter approach in particular. A board game paradigm is developed to allow for a clean, orthogonal manipulation of all variables. The results wholly support the utilitarian relevance approach and offer new perspectives on the face management approach.     

Bypassing the central bottleneck after single-task practice in the psychological refractory period paradigm: Evidence for task automatization and greedy resource recruitment

In this research, the controversial issue of whether the central bottleneck can be bypassed through task automatization was investigated. To examine this issue, participants received six single-task practice sessions with an auditory-vocal task (low vs. high pitch). We then assessed dual-task performance using the analytically tractable psychological refractory period (PRP) paradigm, in which the highly practiced auditory-vocal task was presented as Task 2, along with an unpracticed visual-manual Task 1. The results provide evidence of bottleneck bypass for virtually all the participants (17 out of 20). Several converging tests suggest that the bottleneck reemerged, however, in a follow-up experiment with tasks presented in the opposite order (auditory-vocal Task 1 and visual-manual Task 2). One possible explanation is that tasks greedily recruit central resources when available, even though they can operate without central resources when unavailable.     

Summarizing digital documents: effects of alternate or simultaneous window display

We investigated the effect of window visibility on the computer‐based summarizing of digital documents. Two experiments studied the impact of the simultaneous or alternate display of the windows containing the notepad and source documents. In Experiment 1, the participants were asked to summarize the content of the source documents. In Experiment 2, they were required to copy out sections of the source documents. The results showed that in the alternate condition, the participants performed fewer reading and writing cycles than in the simultaneous condition. Furthermore, in the alternate condition, the writing episodes were both more numerous and more effortful, while quality of the summaries produced using the copying strategy was also affected. These experiments highlight the need for writers to be able to navigate freely and easily between the windows so that they can construct an overall mental representation of their summaries.

Modality-specific and amodal sources of interference in the attentional blink

When two masked targets (T1 and T2) are visually or auditorily presented in rapid succession, processing of T1 produces an attentional blink (AB)--that is, a transient impairment of T2 identification. The present study was conducted to compare the relative impact of masking T1 and T2 between vision and audition. Within a rapidly presented sequence, each of the two verbal targets, discriminated by their offset (Experiment 1) or their onset (Experiment 2), could be followed by either a single item, acting as a mask, or a blank gap. Masking of T2 appeared to be necessary for the occurrence of the AB for both the visual and the auditory modality. However, whereas masking of T1 affected the expression of the visual AB in both experiments, the same effect was observed in the auditory modality only when the targets varied at the onset. These results provide further evidence that processing auditory and visual information is restricted by similar attentional limitations but also suggest that these limits are constrained by properties specific to each sensory system.
