Elicited imitation as a window into developmental stages

In the second language acquisition literature, data of naturally occurring language use are considered the most ideal data to make statements about second-language (L2) development. This study examines to what extent experimentally elicited data can provide an equally valid basis for determining L2 development, by testing predictions derived from Processability Theory regarding the L2 acquisition of the German case system. Using naturally occurring language data, previous research on L2 German case acquisition has uncovered three developmental stages. The present cross-sectional study investigates whether the same stages occur in data obtained from an experimental task (i.e., a computer oral elicited imitation task (OEIT). Thirty-six university L2 learners of German participated in the study. The results show that the elicited data prove comparable to the naturally occurring data. As such, this study corroborates a previous validation study on developmental stages in L2 English, which demonstrated the comparability of naturally occurring and experimentally elicited data. In addition, concerning methodological advancement of the OEIT design, the present study proposes to include a direct measure of comprehension

Synergies between processing and memory in children's reading span.

Previous research has established the relevance of working memory for cognitive development. Yet the factors responsible for shaping performance in the complex span tasks used to assess working memory capacity are not fully understood. We report a study of reading span in 7- to 11-year old children that addresses several contemporary theoretical issues. We demonstrate that both the timing and the accuracy of recall are affected by the presence or absence of a semantic connection between the processing requirement and the memoranda. Evidence that there can be synergies between processing and memory argues against the view that complex span simply measures the competition between these activities. We also demonstrate a consistent relationship between the rate of completing processing operations (sentence reading) and recall accuracy. At the same time, the shape and strength of this function varies with the task configuration. Taken together, these results demonstrate the potential for reconstructive influences to shape working memory performance among children

Anaesthetic challenging in microsurgical flap reconstruction: a systematic review

Background: Anaesthetic management for microvascular reconstructive surgery is challenging and clearly affects the risk of major complications such as flap hypo-perfusion. In this systematic review we explore recent (last 7 years) clinical evidences related to perioperative management and anaesthetic controversy of patients undergoing microvascular reconstructive surgery, especially focused on head and neck surgery with free flaps (FF) and breast reconstructive surgery with deep inferior epigastric perforator flap (DIEP-flap). Methods: A literature search of published clinical studies between 2011 and 2018 was conducted, yielding a total of 4307 papers. Only 150 were eligible, according inclusion and exclusion criteria. Results: 62 studies were selected for this review and categorized in 3 groups: preoperative-intraoperative- postoperative anaesthetic management and areas of controversy for patients undergoing head and neck surgery with FF and breast reconstructive surgery with DIEP-flap. Discussion: Anaesthetic management for flap reconstructive surgery remains an open field of interest with limited evidences regarding a standard care. Main components of research currently are: the need to join standard multidisciplinary enhanced recovery pathways, as well as the necessity to develop a standard intraoperative management. In theatre, the recent hemodynamic parameter “Hypotension Probability Indicator” (HPI) is promising: the advantage to predict a drop in the mean arterial pressure can be more effective than a fluid therapy titrated to maintain SVV less than 13%. Prospective studies are necessary to clarify

Determiners of accuracy when making an expected duration estimation: The role of ‘past’ event/task saliency

One of the important ‘skills’ which is associated with effective time management is the ability to accurately estimate the probable duration of a to-be-scheduled event or task. The present study explored the effect that presenting a highly salient, similar to-be-estimated task had on a subsequent task estimate. Participants in this experiment tended to allocate significantly less time to the completion of a task if they had previously estimated the expected duration of a similar, shorter task. Conversely, they tended to allocate significantly more time to the completion of a task if they had previously estimated the expected duration of a similar but longer task. The results are discussed in relation to future developments in scheduling/time management software

The effect that rounding to prototypical values has on expected duration estimation accuracy

The scheduling component of the time management process was used as a ‘paradigm’ to investigate the estimation of duration of future tasks. Two experiments looked at the effect that the tendency to provide estimates in the form of rounded close approximations had on estimation accuracy. Additionally, the two experiments investigated whether grouping tasks together prior to scheduling would decrease duration estimation error. The majority of estimates provided in both experiments were categorised as rounded close approximations, and were overestimates of the actual time required to complete the experimental tasks. The grouping together of the relatively short tasks used in Experiment 1 resulted in a significant increase in estimation accuracy. A similar result was found in Experiment 2 for relatively long tasks. The results are discussed in relation to the basic processes used to estimate the duration of future tasks, and means by which these scheduling activities can be improved
