Attentional orienting to biologically fear-relevant stimuli: data from eye tracking

Snakes are thought as fear-relevant stimuli (biologically prepared to be associated with fear) which can lead to an enhanced attentional capture when compared fear-irrelevant stimuli. Inherent limitations related to the key-press behaviour might be bypassed with the measurement of eye movements, since they are more closely related to attentional processes than reaction times. An eye tracking technique was combined with the flicker paradigm in two studies. A sample of university students was gathered. In both studies, an instruction to detect changes between the pair of scenes was given. Attentional orienting for the changing element in the scene was analyzed, as well the role of fear of snakes as a moderator variable. The results for both studies revealed a significant shorter time to first fixation for snake stimuli when compared to control stimuli. A facilitating effect of fear of snakes was also found for snakes, presenting the highly fear participants a shorter a time to first fixation for snake stimuli when compared to low-feared participants. The results are in line with current research that supports the advantage of snakes to grab attention due their evo-biological significance.

Using eye-tracking to detect reading difficulties

Taking into account the study of Luegi (2006), where eye movements of 20 Portuguese university students while reading text passages were analyzed, in this article we discuss some methodological issues concerning eye tracking measures to evaluate reading difficulties. Relating syntactic complexity, grammaticality and ambiguity to eye movements, we will discuss the use of many different dependent variables that indicate the immediate and delayed processes in text processing. We propose a new measure that we called Progression-Path which permits analyzing, in the critical region, what happens when the reader proceeds on the sentence instead of going backwards to solve a problem that s/he found (which is the most common expected behavior but not the only one, as is illustrated by some of our examples).

Find the difference! : eye tracking study on information seeking behavior using an online game

With the advent of digital era web applications have become inevitable part of our lives. We are using the web to manage even the financially or ethically sensitive issues. For this reason exploration of information seeking behavior is an exciting area of research. Current study provides insight on information seeking behavior using a classic ‘Find the Difference’ game. 50 university students between the age of 19 and 26 participated in the study. Eye movement data were recorded with a Tobii T120 device. Participants carried out 4 continuous tasks. Each task included two pictures side by side with 7 hidden differences. After finishing the tasks, participants were asked to repeat the game with the same picture set. This data collection methodology allows the evaluation of learning curves. Additionally, participants were asked about their hand preference. For the purpose of analysis the following metrics were applied: task times (including saccades), fixation count and fixation duration (without saccades). The right- and left-hand side on each picture was selected as AOI (Area of Interest) to detect side preference in connection with hand preference. Results suggest a significant difference between male and female participants regarding aggregated task times (male 58.37s respectively female 68.37s), deviation in the number of fixations and fixation duration (apparently female have less but longer fixations) and also in the distribution of fixations between AOIs. Using eyetracking data current paper highlights the similarities and differences in information acquisition strategies respectively reveals gender and education (Arts vs. Sciences) dependent characteristics of interaction.

Universidad Nacional Agraria La Molina – Perú : inclusión social y discriminación social

Como ha sido observado por estudiosos de la educación superior en el Perú y en América Latina, existen dificultades estructurales para el acceso de grupos vulnerables (pobres, minorías étnicas, grupos urbano-marginales, etc.) a la educación superior de calidad. Asimismo, se observa problemas de permanencia de estudiantes sobre quienes prevalecen relaciones de discriminación en sus entornos institucionales. El proyecto titulado “Programa marco interuniversitario para la equidad y la cohesión social de las instituciones de educación superior en América latina” (RIAIPE3, 2011-2013), del que es parte la Universidad Nacional Agraria-La Molina (UNALM), en Perú, es un esfuerzo interinstitucional que entre otros propósitos tuvo: “crear y aplicar un programa marco de referencia para promover las políticas y prácticas en las instituciones de educación superior en América Latina que favorezcan la equidad en poblaciones vulnerables y considere como focos de atención: la exclusión, el acceso, la permanencia en la educación superior de las poblaciones vulnerables (población rural, indígenas, colectivos urbanos marginales, etc.)”. Es en el marco de este proyecto que se realizó el presente estudio. El presente informe de investigación da cuenta de una primera exploración de la problemática de la inclusión social en una universidad pública nacional del Perú, la Universidad Nacional Agraria-La Molina, al empezar la segunda década del siglo XXI, a partir de información de fuente secundaria y autogenerada mediante una encuesta aplicada a estudiantes de pregrado de dos grupos específicos en el segundo semestre del año 2011: estudiantes ingresantes y estudiantes que terminan su carrera.
