This research study explored the systematic thinking modes underlying test anxiety in 706 engineering students through an experiment centred on the cognitive algebra paradigm. The participants had to read 36 experimental scenarios that narrated an imaginary academic assessment situation one by one and then judge the level of anxiety they experience...

p> The COVID-19 pandemic has impacted human life, including educational settings. In Mexico, teachers and students found it necessary to adopt the online modality at all levels. As a result, both students and teachers face new demands and a re-conceptualization of their everyday academic lives. This study explored the engineering students' percepti...

This study explored the cognitive changes to long-term memory as a result of academic learning in 43 Psychology undergraduate students (91% female and 9% male). The participants carried out a conceptual definition task based on the Natural Semantic Networks technique. They defined ten target concepts related to the diagnostic evaluation of learning...

p style="text-align: justify;">This study explored the cognitive mechanism behind information integration in the test anxiety judgments in 140 engineering students. An experiment was designed to test four factors combined (test goal orientation, test cognitive functioning level, test difficulty and test mode). The experimental task required partici...

This study illustrates the application of the Chronometric Constructive Cognitive Learning Evaluation Model to assess learning about human cognition knowledge schema in 48 second-year psychology students (79% females, 21% males). In the first phase, the participants carried out a conceptual definition task based on the Natural Semantic Networks tec...

Students who failed a course on computer usability were Required to take a post season corrective course. They provided conceptual definitions to relevant course schemata concepts before and after the learning period that allowed to draw semantic nets by using a natural semantic network technique. In turn, connexionist computer simulated schemata b...

Se evaluó la usabilidad de una plataforma educativa (NEXUS, www.nexus.uanl.mx/) por medio de la Escala de Usabilidad del Sistema (EUS), el Cuestionario de Usabilidad de Sistemas informáticos (CSUQ) y el seguidor ocular. La muestra se conformó de 29 participantes con una media de edad de 22.5 años. Primero se aplicó el estudio con el seguidor ocular...

Se adaptó la EUS en sus dos versiones: original y positiva, en una población mexicana donde se habla el español, con el objetivo de que después puedan ser utilizadas en otras investigaciones. Para cada versión se utilizaron dos muestras, la versión original se aplicó a 243 participantes y la positiva se aplicó a 173 participantes. El coeficiente de...

Se adaptó el cuestionario CSUQ en una población mexicana donde se habla el español, con el propósito de que pudiera ser utilizado en investigaciones posteriores. Se aplicó el cuestionario CSUQ versión 3 a una muestra de 237 estudiantes de una universidad pública mexicana a través de Internet. Los resultados mostraron que el coeficiente de alfa de C...

The present investigation aims to inquire about the capacity of three implicit instruments to measure the attitude toward natural and urban environments. One hundred and three students from a Mexican public university participated in the investigation. The implicit instruments used were the affective priming technique, the implicit association test...

The present investigation tries to inquire about the capacity of tree implicit instruments to measure the attitude about natural and urban environments. Participated 103 students of a Mexican public university. The implicit instruments used were the affective priming technique, the implicit association test, and the attitude misattribution procedur...

A sample of 59 psychology students and 75 biology students took implicit association tests, explicit preferences tests, and a study of semantic network analysis to observe natural and urban environmental conceptual representations. Results showed that psychology and biology students have similar attitudes and identity to nature. However, they diffe...
