Horizontal eye movement is an essential component of the psychological intervention “eye movement desensitization and reprocessing” (EMDR) used in posttraumatic stress disorder. A hypothesized mechanism of action is an overload of the visuospatial sketchpad and/or the phonological loop of the working memory.

The aim is to explore how eye movements affect the information encoding of the visuospatial sketchpad and the phonological loop.

Fifty healthy young adults performed two immediate recall tasks from the Wechsler Memory Scale: “Corsi Cubes” and “Digits”. Using a within-participants design, up to 16 repetitions of eight seconds of eye-movement and an eye-rest condition were performed.

There were no statistically significant differences between the eye movement and eye rest conditions for either recall task.

In our sample of healthy participants, eye movements did not improve the immediate auditory and visual consolidation memory, undermining this hypothesized mechanism of action of EMDR. However, these findings might also be explained by our exclusion of tests that would stimulate autobiographical memory and our use of a non-clinical sample.

The presentation of a hand grasp facilitates the recognition of subsequent objects when the grasp is coherent with the object to be identified. This out come is usually explained as the integration of two different processes: descriptive visual processes in ventral visual areas and processes in charge of the computations of action metrics in dorsal visual regions. With the aim to explore the temporal dynamics of this interaction, we conducted an experiment in which participants categorized objects preceded by congruent and incongruent hand grasp gestures under different interstimulus interval (ISI) conditions. Hand grasp gestures and target objects were separated by five different interstimulus intervals (ISI): 0, 250, 500, 1000, and 2000 ms.
Results showed significant shorter response times for congruent trials than for incongruent trials for ISI conditions of 250 and 500 ms. However, no effect was found for the other ISIs (0, 1,000 and 2,000). These results suggest that the contribution of automatically driven visuomotor dorsal areas in object recognition is stronger up to 500 ms after prime offset, and that object identification is facilitated by hand gest ure primes just inside this time window (250- 500 ms).

Food labels play a key role in attracting consumers' attention and providing information that could largely influence their purchase decisions. The aim of the present work was to evaluate how consumers acquire information from food labels using eye-tracking measures. Fifty-three consumers completed two tasks in which they evaluated perceived healthfulness of the products and willingness to purchase by looking at three unknown labels of three different products (mayonnaise, pan bread and yogurt).

Participants' eye movements were recorded using an eye tracker while evaluating the labels. Results showed that in order to evaluate their willingness to purchase and perceived healthfulness of unknown food labels, consumers directed their attention to selected areas, searching for specific information such as brand, ingredients, nutritional information and the image on the label, regardless of type of product and label design.

Practical Applications
Attention measures based on memory have been reported to be poor indicators of what consumers actually attend to, mainly due to the fact that attention is not necessarily active and conscious. Eye-tracking measures could be a useful way of studying consumers' processing of visual stimuli such as food labels. Results from the present study suggested that attention toward unfamiliar food labels was mainly determined by top-down factors. Consumers mainly scanned the labels, searching for specific information related to brand, composition and nutritional information.

Consumers have a limited capacity to process all the information they face when deciding their food choices and usually rely on effortless and intuitive thoughts. According to the cognitive-experiential self theory human behavior is determined by the interaction of the two information processing systems:
rational and intuitive. Consumers differ in their preference for these two thinking styles, which leads to differences in how they make their decisions. The aim of the present work was to evaluate the influence of rational and intuitive thinking styles on consumer choices and information processing when evaluating yogurt labels. Seventy-one consumers completed a choice-conjoint task with yogurt labels. Three 2-level variables were considered: fat and sugar content (low vs. high), label background (Background A vs. Background B), and traffic light system (present vs. absent). Consumers were presented with 8 choice
sets composed of two labels on a computer screen, and were asked to indicate which one they would consume. Their eye movements were recorded during the task using an eye-tracker. After completing the conjoint task, consumers completed the Rational Experiential Inventory (REI). Latent class cluster analysis identified two consumer segments with different preference for analytic-rational or intuitive-experiential thinking styles. Consumers who predominantly relied on analytical-rational thinking engaged on a greater information search and a more thoughtful analysis of nutritional information for making their
choices than consumers who preferred intuitive-experiential thinking. Besides, thinking style had a strong influence on the part-worth utilities of the evaluated variables. Results from the present work provide preliminary evidence about the influence of thinking style on consumer food choices, which can
have potential implications for the design of communication strategies aimed at changing dietary patterns.
