Is Written Language Production more Difficult than Oral Language Production? A Working Memory Approach

1994

Abstract Is written language production more difficult than oral language production? Probably, yes. But why? Several experiments were conducted in order to test the impact of low-level activities involved in writing on the performance of higher-level activities also involved in writing. Three assumptions were made: (1) the capacity of working-memory is limited, (2) every component of writing has a cognitive load, and (3) every increase in the load devoted to the activity of one component would lead to a decrease in the remaining resources available for the other components. These low-level activities are more resource-consuming in children than in adults because children have not yet autom…

The effectiveness of multimedia programmes in children's vocabulary learning

2009

The present experiment investigated the effect of three different presentation modes in children's vocabulary learning with a self-guided multimedia programmes. Participants were 135 third and fourth grade children who read a short English language story presented by a computer programme. For 12 key (previously unknown) words in the story, children received verbal annotations (written translation), visual annotations (picture representing the word), or both. Recall of word translations was better for children who only received verbal annotations than for children who received simultaneously visual and verbal annotations or visual annotations only. Results support previous research about cog…

An Evaluation of HCI and CMC in Information Systems within Highly Crowded Large Events

2013

Pervasive systems are composed of a large variety of networked smart devices that supposedly enrich the environment they are deployed in. The access to services provided by a pervasive system should be as natural and “unconscious” as possible. In a large number of cases, the available interaction modality seems to be more oriented towards showing off technological wonders rather than to the actual usability of the interface. In this paper we evaluate and compare two different versions of an information provision system deployed in two editions of a large fair. In particular, we will focus on the Human-Computer Interaction (HCI) and Computer-Mediated-Communication (CMC) points of view. The a…

Research has noticed that imparting TDD-like testing to an early computing curriculum is challenging because it increases technical and cognitive load for the students. This paper addresses the challenge with a software-based solution constructed to facilitate the process of writing tests. The solution allows using a compact while efficient syntax for formulating tests, writing tests into JavaDoc comments, thus close to the source code that implements intended functionalities, and automates the generation of actual test code. The constructed solution -- the ComTest tool -- has now been used in four introductory level programming course offerings. The paper presents the tool and concludes wi…

Cognition and interpersonal communication: The effect of voice quality on information processing and person perception

2014

Abstract Against the backdrop of cognitive load theory (CLT) it was tested if irregular voice increases processing demands on working memory (WM). An experiment was designed to expose N = 54 participants to expository text delivered with a modal and a creaky human voice. Working memory capacity was measured by a secondary task on the visual modality. Listening to a creaky voice quality consumes more cognitive capacity as indicated by the significant decrease in secondary task performance; also, retention of information was found to be impaired. Results are explained within the framework of CLT and implications for professional communication are discussed.

Automatic Timeline Construction and Analysis For Computer Forensics Purposes

2014

International audience; To determine the circumstances of an incident, investigators need to reconstruct events that occurred in the past. The large amount of data spread across the crime scene makes this task very tedious and complex. In particular, the analysis of the reconstructed timeline, due to the huge quantity of events that occurred on a digital system, is almost impossible and leads to cognitive overload. Therefore, it becomes more and more necessary to develop automatic tools to help or even replace investigators in some parts of the investigation. This paper introduces a multi-layered architecture designed to assist the investigative team in the extraction of information left in…

Computer-assisted preparation in conference interpreting

2017

Preparation has been proposed in the literature as one of the most important phases of an interpreting assignment, especially if the subject is highly specialised. Preparing an assignment in advance aims at bridging the linguistic and extra-linguistic gap between conference participants and interpreters and at reducing the cognitive load during interpretation. For these reasons it is considered crucial in ensuring higher interpreting quality. Yet, preparation is generally time-consuming and interpreters may often experience the feeling of not knowing exactly how to perform this task efficiently. Information technology could change this. Even though the first computer-assisted interpreting s…

Behavioral Restriction Determines Left Attentional Bias: Preliminary Evidences From COVID-19 Lockdown

2021

International audience; During the COVID-19 lockdown, individuals were forced to remain at home, hence severely limiting the interaction within environmental stimuli, reducing the cognitive load placed on spatial competences. The effects of the behavioral restriction on cognition have been little examined. The present study is aimed at analyzing the effects of lockdown on executive function prominently involved in adapting behavior to new environmental demands. We analyze non-verbal fluency abilities, as indirectly providing a measure of cognitive flexibility to react to spatial changes. Sixteen students (mean age 20.75; SD 1.34), evaluated before the start of the lockdown (T1) in a battery…

Cognitive Load and Learning in the Study of Multiple Documents

2018

This study had two main purposes. First, to test how the availability of documents in multiple document reading might affect students’ levels of cognitive load. Secondly, to develop an instrument that captures the different sources of load when working with multiple documents. A total of 125 secondary school students read four short texts on transgenic foods and subsequently responded to an open-ended question that required them to write an essay expressing their personal stance towards the topic. Participants in the experimental treatment condition (n = 54) were allowed to go back to the texts any time during the essay task, whereas their peers in the control condition (n = 71) were not al…

La realidad virtual en la fase precompra del turismo de cruceros: un estudio experimental basado en la variable presencia

2023

En el ámbito del turismo, nuevas tecnologías disruptivas como la Realidad Virtual (RV) están remodelando la experiencia del consumidor (Beck et al., 2019; Flavián et al., 2019). En la fase precompra, la RV se posiciona como una herramienta especialmente útil al proveer al consumidor de una simulación sensorial de la experiencia turística de manera previa al viaje (Tussyadiah et al., 2018). Entre las cualidades distintivas de la RV destaca la alta capacidad para generar la sensación de presencia (Biocca, 1997), definida como un estado psicológico en el que el usuario se siente en el entorno virtual representado (Steuer, 1992). No obstante, la exploración y adaptación de la RV en turismo toda…
