Sistemas de Instrucción Asistida por Ordenador: el sistema ABRAXAS

Resumen

Este artículo presenta el desarrollo de un sistema de instrucción asistida por ordenador (IAO), el sistema Abraxas, dirigido a los estudiantes de Psicología. Su objetivo es enseñar la metodología del análisis factorial, tema de considerable dificultad para una gran mayoría de los estudiantes. Desde hace unos años, los sistemas IAO se han convertido en herramientas cotidianas de trabajo en distintos ámbitos de investigación y aplicación. Sin embargo, dichos sistemas no cumplen su objetivo en la gran mayoría de los casos, siendo una de las causas que durante el proceso de diseño y desarrollo, no se toman en cuanta una serie de pautas que se deben seguir al diseñar y desarrollar sistemas IAO, de modo que se optimice el aprendizaje real de los usuarios. Abraxas se divide en 5 módulos instruccionales: introducción temática, idea de correlación, idea de factor, desarrollo matemático y modelos factoriales. En cada módulo se usan distintos tipos de pantallas, de enseñanza, criterialesy de evaluación, y cada uno de estos módulos se ha valorado con potenciales usuarios desde el momento de su diseño; los resultados han indicado el éxito de esta estrategia.     

Immigration and the interplay among citizenship, identity and career: The case of Ethiopian immigration to Israel

Migration is a common phenomenon of the globalization era. In this article we explore the interplay of three foundational concepts in the migration experiences of Ethiopian Jewish immigrants in Israel: citizenship, identity and career. Through our analysis we examine the multiple layers of being an immigrant citizen. Following immigration, as reflected in empirical studies with members of this community, we have observed tensions between inclusion and exclusion, equality and difference, work and family as well as gender role transformation, family restructuring, and generational differences. These issues are discussed in the context of the development of active citizenship and career. Career development is found to be a core process in the enactment of citizenship, the promotion of a sense of belonging and deeply related to identity formation. Identity as an overarching perspective, with its personal and collective meanings, plays an important role at the intersection between citizenship and career.     

Wives’ career progression among dual-career ethno-cultural couples: Husbands’ perspectives

This study explored the perspectives of husbands regarding the participation of their wives in professional occupations. The participants included nine South African Indian men in dual-career marriages (ages ranging from 25 to 54 years old). The completed semi-structured, life-story interviews focused on the socio-historic and contemporary influences on marital and familial dynamics with working spouses. Thematic analysis of the data revealed the husbands to be supportive of their spouses across familial and occupational roles. The findings contradict the stereotype that South African Indian husbands are unsupportive of their working spouses.     

Sense of agency for mental actions: Insights from a belief-based action-effect paradigm

A substantial body of research has converged on the idea that the sense of agency arises from the integration of multiple sources of information. In this study, we investigated whether a measurable sense of agency can be detected for mental actions, without the contribution of motor components. We used a fake action-effect paradigm, where participants were led to think that a motor action or a particular thought could trigger a sound. Results showed that the sense of agency, when measured through explicit reports, was of comparable strength for motor and mental actions. The intentional binding effect, a phenomenon typically associated with the experience of agency, was also observed for both motor and mental actions. Taken together, our results provide novel insights into the specific role of intentional cues in instantiating a sense of agency, even in the absence of motor signals.     

Can driving condition prompt systems improve passenger comfort of intelligent vehicles? A driving simulator study

The main trend in the development of intelligent vehicles has been on ensuring comfort, safety, efficiency, and environmental sustainability. However, current research focuses primarily on the safety and energy saving of intelligent vehicles, and a comfortable driving experience through a human–machine interaction system has not been sufficiently investigated. This study used a high-fidelity 6-degree-of-freedom driving simulator to evaluate the impact of an independently-designed vehicle driving condition prompt (DCP) systems on subjective passenger comfort and motion sickness. The experiment showed that when future driving information is obtained through the vehicle DCP systems, the passengers' subjective comfort is improved, motion sickness is alleviated, and the degree of passenger posture instability is reduced. These conclusions contribute toward improving the comfort of autonomous vehicles and providing a reference for the future design of human–machine interaction systems for intelligent vehicles.     

Semantic Information and the Syntax of Propositional Attitude Verbs

Propositional attitude verbs, such as think and want, have long held interest for both theoretical linguists and language acquisitionists because their syntactic, semantic, and pragmatic properties display complex interactions that have proven difficult to fully capture from either perspective. This paper explores the granularity with which these verbs’ semantic and pragmatic properties are recoverable from their syntactic distributions, using three behavioral experiments aimed at explicitly quantifying the relationship between these two sets of properties. Experiment 1 gathers a measure of 30 propositional attitude verbs’ syntactic distributions using an acceptability judgment task. Experiments 2a and 2b gather measures of semantic similarity between those same verbs using a generalized semantic discrimination (triad or “odd man out”) task and an ordinal (Likert) scale task, respectively. Two kinds of analyses are conducted on the data from these experiments. The first compares both the acceptability judgments and the semantic similarity judgments to previous classifications derived from the syntax and semantics literature. The second kind compares the acceptability judgments to the semantic similarity judgments directly. Through these comparisons, we show that there is quite fine‐grained information about propositional attitude verbs’ semantics carried in their syntactic distributions—whether one considers the sorts of discrete qualitative classifications that linguists traditionally work with or the sorts of continuous quantitative classifications that can be derived experimentally.     

Empirical and modeling study of emotional state dynamics in social videogame paradigms

The objective of this work was to study the dynamics of human emotional states in the process of social interaction in a virtual environment. The previously developed for this purpose prototypes of the virtual actor (NPC) and its virtual environment simulator “Teleport” underwent significant re-design and modification. The experimental platform was re-implemented and used in experiments with college student participants, combining electromyography, emotion recognition in facial recordings and model-based game log analysis in a social videogame paradigm. Participants interacted with two virtual actors implemented based on the eBICA cognitive architecture (Samsonovich, 2013, 2018). Positive correlations were found between eBICA model predictions and participant affects extracted from their facial expressions and facial muscle activity. Affective dynamics of social phenomena, such as the establishment of partnership or an act of betrayal, were characterized and found consistent with the model predictions. Other findings include a gradually developing emotional reaction, possibly due to the integration of appraisals of game events. Overall, obtained results confirm the eBICA model, suggesting its further extension and refinement.     

人工感知技术的医学伦理探究

人工感知技术突破人类自然感官的限制,在拓展人类对世界和自我认知的同时带来了新的医学伦理挑战,“侵入性”概念在医疗器械开发、监管、市场准入和使用中起着重要作用,但传统的侵入性和非侵入性概念已经不再适用于新兴医疗神经技术的伦理讨论。人工感知技术的发展不仅关乎科学技术和实际应用,还涉及人类的价值观、医学伦理和人类自身文明的未来发展方向。在当前认知方式的变革和转型中,因为人工感知的临床应用对人体的特殊介入方式,思考人工感知技术带来的医学伦理新问题,重新反思医学技术与人类的关系,成为医学哲学当务之急。

     

视觉显示技术的新视角：交互显示

交互显示技术是近年人机界面显示技术中形成的一种新型显示技术。这种技术能根据用户的即时输入或操作特点改变初始界面中的显示内容或方式。交互显示技术可分为简单交互显示技术，如鱼眼技术及其应用，和智能交互显示技术，如速率耦合平滑技术，目标气泡技术等。目前的交互显示技术具有动态性、即时性和智能性等特点，但仍存在如交互方式单一，智能性不高等问题，未来研究需强调显示内容变化、交互形式的多样性及其高级智能交互技术等方面的研究。
