ABSTRACT
This study combined an event schema approach with top-down processing perspectives to investigate whether high-functioning children and adults with autism spectrum disorder (ASD) spontaneously attend to and remember context-relevant aspects of scenes. Participants read one story of story-pairs (e.g., burglary or tea party). They then inspected a scene (living room) of which some objects were relevant in that context, irrelevant (related to the non-emphasized event) or neutral (scene-schema related). During immediate and delayed recall, only the (TD) groups selectively recalled context-relevant objects, and significantly more context-relevant objects than the ASD groups. Gaze-tracking suggests that one factor in these memory differences may be diminished top-down effects of event schemas on initial attention (first ten fixations) to relevant items in ASD.

ABSTRACT
In serial memory for spatial information, performance is impaired when distractors are interpolated between to-be-remembered (TBR) stimuli (Tremblay, Nicholls, Parmentier, & Jones, 2005). The so-called sandwich effect, combined with the use of eye tracking, served as a tool for examining the role of the oculomotor system in serial memory for spatial information. Participants had to recall the order in which sequences of TBR locations were presented. In some trials, to-be-ignored blue dots were presented after each TBR location. Our results show that response locations shift toward the location of the distractors, and this deviation is related to the eye movement deviation toward the distractor location. These results suggest that TBR and to-be-ignored locations are encoded onto a common map that could lie within the oculomotor system. Interference in memory for spatial information is interpreted in light of a model of oculomotor behavior (Godijn & Theeuwes, 2002b).

ABSTRACT
Two problem-solving experiments investigated the relationship between planning and the cost of accessing goal-state information using the theoretical framework of the soft constraints hypothesis (Gray & Fu, 2004; Gray, Simms, Fu, & Schoelles, 2006). In Experiment 1, 36 participants were allocated to low, medium, and high access cost conditions and completed a problem-solving version of the Blocks World Task. Both the nature of planning (memory based or display based) and its timing (before or during action) changed with high goal-state access cost (a mouse movement and a 2.5-s delay). In this condition more planning before action was observed, with less planning during action, evidenced by longer first-move latencies, more moves per goal-state inspection, and more short (≤0.8 s) and long (>8 s) “preplanned” intermove latencies. Experiment 2 used an eight-puzzle-like transformation task and replicated the effect of goal-state access cost when more complex planning was required, also confirmed by sampled protocol data. Planning before an episode of move making increased with higher goal-state access cost, and planning whilst making moves increased with lower access cost. These novel results are discussed in the context of the soft constraints hypothesis.

ABSTRACT
Children with dyslexia and attention deficit disorders often have problems in short term memory, yet can benefit from learning strategies for remembering. In this paper, we describe the design of a multimedia educational game called Memory Challenge to help children with Specific Learning Difficulties (SpLDs) learn strategies for memory and to develop their cognitive skills. We focus in our approach on the involvement of children with SpLDs and domain specialists and practitioners in the design process. Involving various
participants from our target population (native Arabic-speaking users) in different stages of our design process was effective in obtaining an insight into the needs of people with SpLDs and has contributed to the design with actionable implications.

ABSTRACT
Here we report evidence from a new eye-tracking measure of relational memory that suggests that 9-month-old infants can encode memories in terms of the relations among items, a function putatively subserved by the hippocampus. Infants learned about the association between faces that were superimposed on unique scenic backgrounds. During test trials, infants were shown three faces presented on a familiar scene. All three faces were equally familiar; however, one had been presented with the test background earlier. Visual behavior was recorded continuously using a TOBII eye tracker. Infants looked preferentially at the face that matched the test background very early in the trial; however, the time course of this preferential looking effect varied as a function of delay. These results suggest that by 9 months of age infants can form memories that represent the relations among items and maintain them over short delays.

ABSTRACT
Fixation duration for same-race (i.e., Asian) and other-race (i.e., Caucasian) female faces by Asian infant participants between 4 and 9 months of age was investigated with an eye-tracking procedure. The age range tested corresponded with prior reports of processing differences between same- and other-race faces observed in behavioral looking time studies, with preference for same-race faces apparent at 3 months of age and recognition memory differences in favor of same-race faces emerging between 3 and 9 months of age. The eye-tracking results revealed both similarity and difference in infants’ processing of own- and other-race faces. There was no overall fixation time difference between same race and other race for the whole face stimuli. In addition, although fixation time was greater for the upper half of the face than for the lower half of the face and trended higher on the right side of the face than on the left side of the face, face race did not impact these effects. However, over the age range tested, there was a gradual decrement in fixation time on the internal features of other-race faces and a maintenance of fixation time on the internal features of same-race faces. Moreover, the decrement in fixation time for the internal features of other-race faces was most prominent on the nose. The findings suggest that (a) same-race preferences may be more readily evidenced in paired comparison testing formats, (b) the behavioral decline in recognition memory for other-race faces corresponds in timing with a decline in fixation on the internal features of other-race faces, and (c) the center of the face (i.e., the nose) is a differential region for processing same- versus other-race faces by Asian infants.

ABSTRACT
In categorization, emphasizing task-relevant information is critical for efficient performance. Such attentional optimization can occur concurrently with learning category structures, or may be delayed until after the categories have been mastered. Thus far, delayed attentional optimization has only been found in rule-based categories. The present studies use eye-tracking to investigate attentional optimization in rule-based (RB) and information integration (II) categories. Because working memory capacity is thought to reflect the ability to suppress task-irrelevant information, we also examined the relationship between Aospan performance and attentional optimization. We found that delayed attentional optimization is not a universal characteristic of RB categories, and that working memory predicts early attentional learning in simple categories, but predicts speed of category learning in complex categories. Working memory capacity's influence on optimization and performance does not differ between RB and II learning.

ABSTRACT
By the late 19th century, tests of adults’ shortterm visual memory—how much one retains from a briefly presented display—had acquired a familiar character: An alphanumeric array was presented, removed, and participants were asked to report the items (Wundt, 1912). These ‘whole report’ tests revealed capacities of 3-4 items (Cattell, 1886; Sperling, 1960). However, participants often felt they had seen more items, but forgotten them before report. A crucial innovation was to ask for just a ‘partial report’, cuing participants to sample from their memory (e.g. a high-pitched tone might cue report of the middle of three rows of letters) (Sperling, 1960). If the cue occurs after display offset (a ‘post-cue’) and the sampled subsets are random, then accurate reports mean all the presented items had been stored. This clever methodological change exposed a new—early, high-capacity (~9 items), and fast-decaying (~200 ms half-life)—memory system dubbed ‘iconic memory’ (Neisser, 1967). In this sense, then, the study of infants’ visual memory is still rooted in the conventions of the 19th century: No one has yet asked infants for a partial report. ...

ABSTRACT
The authors explored different aspects of encoding strategy use in primary school children by including (a) an encoding strategy task in which children's encoding strategy use was recorded through a remote eye-tracking device and, later, free recall and recognition for target items was assessed; and (b) tasks measuring resistance to interference (flanker task) and inhibition of attention to task-irrelevant stimuli (distractibility). Results revealed that the ability to inhibit distraction and resist interference undergoes developmental changes between the ages of 7–10 years. At the same time, children's capability to strategically focus on task-relevant aspects also continues to improve in primary school years. Although there were substantial relationships between encoding strategies and later recognition, encoding strategies appeared to be unrelated to basic aspects of attentional control.

ABSTRACT
This research investigated the role of individual differences for the control of attention in the early stages of self-regulation. Theories on the development of addiction posit that repeated substance use alters memory structures referring to the substance through classical conditioning processes, leading to the attention-grabbing properties of the substance. The authors predicted that such memory structures influence attentional processes toward the substance, but only in individuals with low executive control. One executive function that is closely related to attention control is working memory capacity. Using eye-tracking methodology, the authors found individual differences in an alcohol single category implicit association test to predict indicators of attention allocation such as initial orienting and attention maintenance for social drinkers low but not high in working memory capacity. This effect primarily resulted from the controlled attention component as opposed to the short-term memory component of working memory capacity. Implications and directions for further research are discussed.

ABSTRACT
What role does language play during attention allocation in perceiving and remembering events? We recorded adults’ eye movements as they studied animated motion events for a later recognition task. We compared native speakers of two languages that use different means of expressing motion (Greek and English). In Experiment 1, eye movements revealed that, when event encoding was made difficult by requiring a concurrent task that did not involve language (tapping), participants spent extra time studying what their language treats as the details of the event. This ‘linguistic encoding’ effect was eliminated both when event encoding was made easier (no concurrent task) and when the concurrent task required the use of language (counting aloud). In Experiment 2, under conditions of a delayed concurrent task of counting aloud, participants used language covertly just prior to engaging in the additional task. Together, the results indicate that language can be optionally recruited for encoding events, especially under conditions of high cognitive load. Yet, these effects are malleable and flexible and do not appear to shape core biases in event perception and memory.

ABSTRACT
With only two to five slots of visual working memory (VWM), humans are able to quickly solve complex visual problems to near optimal solutions. To explain the paradox between tightly constrained VWM and impressively complex human visual problem-solving ability, we propose several principles for dynamic VWM allocation. In particular, we propose that complex visual information is represented in a temporal manner using only a few slots of VWM that include global and local visual chunks. We built a model of human traveling salesman problem solving based on these principles of VWM allocation and tested the model with eye-movement data. Exactly as the model predicted, human eye movements during traveling salesman problem solving have precise quantitative regularities with regard to both the general statistical pattern of attentional fixations and how they vary across individuals with different VWM capacities. Even though VWM capacity is very limited, eye movements dynamically allocate VWM resources to both local and global information, enabling attention to fine details without loss of the big picture.

ABSTRACT
The idea that the medial temporal lobe (MTL), traditionally viewed as an exclusive memory system, may also subserve higher-order perception has been debated fiercely. To support this suggestion, monkey and human lesion studies have demonstrated that perirhinal cortex damage impairs complex object discrimination. The interpretation of these findings has, however, been disputed because these impairments may reflect a primary deficit in MTL-mediated working memory processes or, in the case of human patients, undetected damage to visual processing regions beyond the MTL. To address these issues, this study investigated object perception in two human amnesic patients who were chosen on the basis of their lesion locations and suitability for detailed neuroimaging investigation. A neuropsychological task with minimal working memory demands was administered in which participants assessed the structural coherency of single novel objects. Critically, only the patient with perirhinal atrophy was impaired. Moreover, volumetric and functional neuroimaging data demonstrated that this deficit cannot be attributed to the dysfunction of visual cortical areas. Additional analyses of eye-movement patterns during the perceptual task revealed an inability of this patient to detect structural incoherency consistently. This study uses a combination of techniques to provide strong evidence that the perirhinal cortex subserves perception and suggests that the MTL perceptual-mnemonic debate cannot be dismissed on the basis of anatomy or a working memory impairment.

ABSTRACT
An investigation into user attention and design quality in websites is described. The investigation combined reported attention to areas of interest, with free memory recall and a questionnaire to assess whether areas of interest that users attended to were also remembered and rated well in terms of aesthetic design and usability. Users' memory of areas of interest and design features agreed reasonably well with their reported attention. The sites which were rated more attractive overall had an open layout, extensive use of animations which drew users' attention, and good aesthetic design ratings. Aesthetics was the more important determinant for overall attractiveness; whereas content, brand and usability were more important for overall preference. Based on the analysis, design guidelines for directing user attention are proposed.

Abstract
Eye-tracking has been used as a methodology for some time in various disciplines, but it has not been applied to date in translation studies. This paper presents results from a preliminary investigation which seeks to answer two questions: Firstly, is eye-tracking, in general, a useful research methodology for investigating translators' interaction with Translation Memory tools? Secondly, what can eye-tracking data tell us about cognitive load when translators deal with different match types in Translation Memories? The results demonstrate that eye-tracking data, including pupil dilation measurements and gaze replays, in association with retrospective protocols promise to be a very effective methodology for future research into translation processes. The results also suggest that the cognitive load for exact matches in Translation Memory tools is much lower than for other match types, that cognitive load for machine translation matches is close to fuzzy matches of between 80-90% value, and that “no matches” require the highest level of cognitive load.

Abstract
Serial memory for spatial locations increases as the distance between successive stimuli locations decreases. This effect, known as the path length effect [Parmentier, F. B. R., Elford, G., & Maybery, M. T. (2005). Transitional information in spatial serial memory: Path characteristics affect recall performance. Journal of Experimental Psychology: Learning, Memory & Cognition, 31, 412–427], was investigated in a systematic manner using eye tracking and interference procedures to explore the mechanisms responsible for the processing of spatial information. In Experiment 1, eye movements were monitored during a spatial serial recall task – in which the participants have to remember the location of spatially and temporally separated dots on the screen. In the experimental conditions, eye movements were suppressed by requiring participants to incessantly move their eyes between irrelevant locations. Ocular suppression abolished the path length effect whether eye movements were prevented during item presentation or during a 7 s retention interval. In Experiment 2, articulatory suppression was combined with a spatial serial recall task. Although articulatory suppression impaired performance, it did not alter the path length effect. Our results suggest that rehearsal plays a key role in serial memory for spatial information, though the effect of path length seems to involve other processes located at encoding, such as the time spent fixating each location and perceptual organization.
