ELAN Analysis Companion (EAC) : A Software Tool for Time-course Analysis of ELAN-annotated Data
- 2016

- ELAN is a widely used and free (in both senses) annotation software for behavioral or other events that unfold over time. We report on and release a stand-alone program that expands on ELAN's capabilities in two ways: 1) it allows the researcher to plot and export time-course analysis data directly from ELAN's native annotation files, allowing for hassle-free analysis in the time domain; and 2) it allows the researcher to weight ELAN's built-in annotator reliability rating based on the duration of the coded events. This software is released under an open license.

Sampling frequency and eye-tracking measures : how speed affects durations, latencies, and more

- We use simulations to investigate the effect of sampling frequency on common dependent variables in eye-tracking. We identify two large groups of measures that behave differently, but consistently. The effect of sampling frequency on these two groups of measures are explored and simulations are performed to estimate how much data are required to overcome the uncertainty of a limited sampling frequency. Both simulated and real data are used to estimate the temporal uncertainty of data produced by low sampling frequencies. The aim is to provide easy-to-use heuristics for researchers using eye-tracking. For example, we show how to compensate the uncertainty of a low sampling frequency with more data and post-experiment adjustments of measures. These findings have implications primarily for researchers using naturalistic setups where sampling frequencies typically are low.

Comparing scanpaths during scene encoding and recognition: A multi-dimensional approach
- 2012

Ingår i: Journal of Eye Movement Research. - 1995-8692. ; 5:4:3, s. 1-14

Tidskriftsartikel (refereegranskat)abstract
- Abstract in UndeterminedComplex stimuli and tasks elicit particular eye movement sequences. Previous research has focused on comparing between these scanpaths, particularly in memory and imagery research where it has been proposed that observers reproduce their eye movements when recognizing or imagining a stimulus. However, it is not clear whether scanpath similarity is related to memory performance and which particular aspects of the eye movements recur. We therefore compared eye movements in a picture memory task, using a recently proposed comparison method, MultiMatch, which quantifies scanpath similarity across multiple dimensions including shape and fixation duration. Scanpaths were more similar when the same participant's eye movements were compared from two viewings of the same image than between different images or different participants viewing the same image. In addition, fixation durations were similar within a participant and this similarity was associated with memory performance.

Using eye-tracking to trace a cognitive process: Gaze behavior during decision making in a natural environment
- 2013
-
Ingår i: Journal of Eye Movement Research. - : University of Bern. - 1995-8692. ; 6:1, s. 3-14

Tidskriftsartikel (refereegranskat)abstract
- The visual behaviour of consumers buying (or searching for) products in a supermarket was measured and used to analyse the stages of their decision process. Traditionally metrics used to trace decision-making processes are difficult to use in natural environments that often contain many options and unstructured information. Unlike previous attempts in this direction (i.e. Russo & Leclerc, 1994), our methodology reveals differences between a decision-making task and a search task. In particular the second (evaluation) stage of a decision task contains more re-dwells than the second stage of a comparable search task. This study addresses the growing concern of taking eye movement research from the laboratory into the ‘real-world’, so findings can be better generalised to natural situations.
