On the accuracy of code complexity metrics: A neuroscience-based guideline for ...
Hao, Gao; Hijazi, Haytham; Durães, João; Medeiros, Julio; Couceiro, Ricardo; Lam, Chan Tong; Teixeira, César A.; Castelhano, JoãoComplexity is the key element of software quality. This article investigates the problem of measuring code complexity and discusses the results of a controlled experiment to compare different views and methods to measure code complexity. Participants (27 programmers) were asked to read and (try to) understand a set of programs, while the complexity of such programs is assessed through different methods and pers...
Software Bug Detection Causes a Shift From Bottom-Up to Top-Down Effective Conn...
Castelhano, João; Duarte, Isabel C.; Couceiro, Ricardo; Medeiros, Júlio; Durães, João; Afonso, Sónia; Madeira, Henrique; Castelo Branco, MiguelThe neural correlates of software programming skills have been the target of an increasing number of studies in the past few years. Those studies focused on error-monitoring during software code inspection. Others have studied task-related cognitive load as measured by distinct neurophysiological measures. Most studies addressed only syntax errors (shallow level of code monitoring). However, a recent functional...
Intelligent Biofeedback Augmented Content Comprehension (TellBack)
Hijazi, Haytham; Couceiro, Ricardo; Castelhano, João; De Carvalho, Paulo; Castelo Branco, Miguel; Madeira, HenriqueAssessing comprehension difficulties requires the ability to assess cognitive load. Changes in cognitive load induced by comprehension difficulties could be detected with an adequate time resolution using different biofeedback measures (e.g., changes in the pupil diameter). However, identifying the Spatio-temporal sources of content comprehension difficulties (i.e., when, and where exactly the difficulty occurs...
Can EEG Be Adopted as a Neuroscience Reference for Assessing Software Programme...
Medeiros, Júlio; Couceiro, Ricardo; Duarte, Gonçalo; Durães, João; Castelhano, João; Duarte, Catarina; Castelo-Branco, Miguel; Madeira, HenriqueAn emergent research area in software engineering and software reliability is the use of wearable biosensors to monitor the cognitive state of software developers during software development tasks. The goal is to gather physiologic manifestations that can be linked to error-prone scenarios related to programmers' cognitive states. In this paper we investigate whether electroencephalography (EEG) can be applied ...
A Tool For ECG Analysis as a Module of a Tele-Monitoring System
Rocha, Teresa; Paredes, Simão; Cabiddu, Ramona; Couceiro, Ricardo; Carvalho, Paulo; Henriques, JorgeThis work describes a Matlab1 tool originally developed in the HeartCycle2 European project and updated during the cardioRisk3 project. It addresses the analysis of the electrocardiogram (ECG) signal in the context of the management of heart failure (HF) patients. The toolbox is composed of six modules, focusing on the major clinical aspects relevant to HF diagnosis: signal delineation, detection of auricular a...
