Selective attentional delays and attentional capture among multiple visual onset elements
… were not due to response competition, random attentional capture by noise, or difficulties in locating the target. It is suggested that simultaneous onset stimuli are perceived initially as a single object and delays in processing a single stimulus are due to difficulties in perceptually …

Selective attention under different pressure sources and perceptual loads
… with the pressure effects by introducing an attentional capture task to Experiment 2’s design. We replicated the findings for the flanker effect in Experiment 2, and also found that distraction from task-irrelevant stimuli was not affected by outcome pressure. Experiment 4 used emotional …

Tracing the Dynamics of Value-Based Attention: from Generalization to Disengagement
… stimuli previously associated with reward can capture attention even when they are no longer relevant or physically salient—a phenomenon known as Value-Modulated Attentional Capture (VMAC). While such value-driven biases are typically adaptive, facilitating the prioritization of motivationally …

Task Switching and Distractibility
… (e.g. Eriksen & Eriksen, 1974) and with the attentional capture task (e.g. Theeuwes, 1990), even when there was no overlap between the stimuli and responses for the two tasks, and when task-repeated and switch trials were presented within the same block (in AAABBB designs). This research also …

Somatic salience and sensory precision in persistent depression
… Studies 4 (Chapter 6) and 5 (Chapter 7) measured attentional capture by task-irrelevant and predictive sensory cues respectively. Study 6 (Chapter 8) partially replicated Studies 4 and 5 and used the resulting data to estimate the group-level sensory precision and salience parameters of a …

Visual attention in naturalistic scenes across the lifespan.
Visual attentional skills continue to develop through childhood and do not reach maturity until adolescence. On the other end of the spectrum, older adults’ visual attentional skills are declining with age. The development and decline of these skills can lead to difficulties in day to day …

Attentional Control in Young Drivers: Does Training Help or Hinder Bottom-Up Processing in a Dynamic Driving Environment?
… protecting them from the adverse effect of attentional capture by stimulus movements that coexist with latent road hazards.</p>

The Role of Awareness in the Error -Processing of Involuntary Eye Movements
… onset, have a powerful effect on our covert (attentional capture) and overt (oculomotor capture) behavior. Given the ubiquitous nature of eye movements in everyday activities it is important to determine whether oculomotor capture by task-irrelevant events, which is often impervious to …

Working memory, selective visual attention and hierarchical perception
… on whether or not this top-down process of attentional capture from working memory is an automatic mechanism where attention gets deployed without a need for voluntary effort, and on the neural process of this endogenous control working in conjunction with bottom-up exogenous factor. So far …

Awareness in ageing
… components found that older adults had reduced attentional capture of auditory stimuli and allocated less attention to processing target stimuli. However, behavioural performance was equivalent across groups, indicating that the underlying differences found in sensory processing did not …

ASSESSING THE ASSOCIATION BETWEEN ATTENTIONAL BIAS TO CLIMATE CHANGE IMAGES AND CLIMATE ANXIETY
… aimed to extend previous research regarding attentional bias and anxiety by assessing the relationship between attentional bias and climate change anxiety. Participants completed an eye-tracking task where they were asked to view climate change relevant images paired with climate irrelevant …

The relationship between encoding and recall for the identities and locations of objects
… and recall can be influenced using a lower-level attentional capture technique to draw. Experiment 3 investigated whether a primacy or recency effect was found for object identity and location memory. No such evidence was obtained for either. Experiment 4 provided evidence that information about …

An ERP Investigation into the Influence of Spatial Relevance on Attentional Deployment
… within spatially relevant regions; however, the attentional mechanisms underlying this differential processing are not fully understood. Two hypotheses could explain the attentional mechanisms involved: firstly, information in spatially relevant regions may be enhanced, such that distractors in …

Developmental differences in the vulnerability to auditory distraction: children vs. adults
… in the thesis highlight how rehearsal and attentional control play a role in the observed developmental differences. Rehearsal and attention do not work in isolation but rather interact with one another to enable successful execution of many different tasks (Elliott et al., 2016). One such …

Can Meaning Associated with Perceptual Grouping Modulate Attention?
… factors jointly influences the settings of the attentional filter (Spalek, Falcon & Di Lollo, 2006) such that only task-relevant information is selected for further processing. However, biologically- and socially-important stimuli like affective faces are proposed to influence allocation of …

Towards a better understanding of prioritization of visual information during preview search
… to eliminate the contribution of bottom-up attentional capture by the onset of the second set of items, we included a 200ms blank display between the initial preview and the final search display. In five experiments, we demonstrated that the preview benefit relies preferentially on …

Emotional engagement and orienting: the effects of picture size on affective response
… of distinct processes (action preparation, attentional capture, and subjective emotional state) is affected when reducing the retinal size of a picture. Studies 1-3 examined the effects of picture size on emotional response. Subjective feeling of engagement, as well as sympathetic …

Orientation-specific Control of Attention
… distractor matched to a sought-for color captures attention involuntarily, thus violating either temporal or spatial control of attention. However, whether an irrelevant distractor that matches a sought-for orientation can capture attention is still unknown. A task of rapid serial visual …
