Resumen

AbstractSpatial cues help participants detect a visual target when it appears at the cued location. One hypothesis for this cueing effect, called selective perception, is that cueing a location enhances perceptual encoding at that location. Another hypothesis, called selective decision, is that the cue has no effect on perception, but instead provides prior information that facilitates decision-making. We distinguished these hypotheses by comparing a simultaneous display with two spatial locations to sequential displays with two temporal intervals. The simultaneous condition had a partially valid spatial cue, and the sequential condition had a partially valid temporal cue. Selective perception predicts no cueing effect for sequential displays given there is enough time to switch attention. In contrast, selective decision predicts cueing effects for sequential displays regardless of time. We used endogenous cueing of a detection-like coarse orientation discrimination task with clear displays (no external noise or postmasks). Results showed cueing effects for the sequential condition, supporting a decision account of selective attention for endogenous cueing of detection-like tasks.

Resumen

Endogenous cueing of attention enhances sensory processing of the attended stimulus (perceptual sensitivity) and prioritizes information from the attended location for guiding behavioral decisions (spatial choice bias). Here, we test whether sensitivity and bias effects of endogenous spatial attention are under the control of common or distinct mechanisms. Human observers performed a multialternative visuospatial attention task with probabilistic spatial cues. Observers’ behavioral choices were analyzed with a recently developed multidimensional signal detection model (the m-ADC model). The model effectively decoupled the effects of spatial cueing on sensitivity from those on spatial bias and revealed striking dissociations between them. Sensitivity was highest at the cued location and not significantly different among uncued locations, suggesting a spotlight-like allocation of sensory resources at the cued location. On the other hand, bias varied systematically with cue validity, suggesting a graded allocation of decisional priority across locations. Cueing-induced modulations of sensitivity and bias were uncorrelated within and across subjects. Bias, but not sensitivity, correlated with key metrics of prioritized decision-making, including reaction times and decision optimality indices. In addition, we developed a novel metric, differential risk curvature, for distinguishing bias effects of attention from those of signal expectation. Differential risk curvature correlated selectively with m-ADC model estimates of bias but not with estimates of sensitivity. Our results reveal dissociable effects of endogenous attention on perceptual sensitivity and choice bias in a multialternative choice task and motivate the search for the distinct neural correlates of each. NEW & NOTEWORTHY Attention is often studied as a unitary phenomenon. Yet, attention can both enhance the perception of important stimuli (sensitivity) and prioritize such stimuli for decision-making (bias). Employing a multialternative spatial attention task with probabilistic cueing, we show that attention affects sensitivity and bias through dissociable mechanisms. Specifically, the effects on sensitivity alone match the notion of an attentional “spotlight.” Our behavioral model enables quantifying component processes of attention, and identifying their respective neural correlates.

Resumen

Existing research has found that spatial attention alters how various stimulus properties are perceived (e.g., luminance, saturation), but few have explored whether it improves the accuracy of perception. To address this question, we performed two experiments using modified Posner cueing tasks, wherein participants made speeded detection responses to peripheral colour targets and then indicated their perceived colours on a colour wheel. In E1, cues were central and endogenous (i.e., prompted voluntary attention) and the interval between cues and targets (stimulus onset asynchrony, or SOA) was always 800 ms. In E2, cues were peripheral and exogenous (i.e., captured attention involuntarily) and the SOA varied between short (100 ms) and long (800 ms). A Bayesian mixed-model analysis was used to isolate the effects of attention on the probability and the fidelity of colour encoding. Both endogenous and short-SOA exogenous spatial cueing improved the probability of encoding the colour of targets. Improved fidelity of encoding was observed in the endogenous but not in the exogenous cueing paradigm. With exogenous cues, inhibition of return (IOR) was observed in both RT and probability at the long SOA. Overall, our findings reinforce the utility of continuous response variables in the research of attention.

Resumen

Self-referential stimuli such as self-face surpass other-referential stimuli in capture of attention, which has been attributed to attractive perceptual features of self-referential stimuli. We investigated whether temporarily established self-referential stimuli are different from other-referential cues in guiding voluntary visual attention. Temporarily established self-referential or friend-referential shapes served as central cues in Posner's endogenous cueing task. We found that, relative to friend-referential cues, self-referential cues induced smaller cueing effect (i.e., the difference in reaction times to targets at cued and uncued locations) when the interstimulus interval was short but larger cueing effect when the interstimulus interval was long. Our findings suggest that temporarily established self-referential cues are more efficient to capture reflexive attention at the early stage of perceptual processing and to shift voluntary attention at the later stage of perceptual processing.

Resumen

The experiments in this thesis were designed to examine the consequences of endogenous and exogenous spatial cueing in a dual-task set-up. The first experiments, presented in Chapters 2 and 3, explored whether spatial attention generalises across dimensions in the same location. Chapters 4, 5, and 6 contain a second series of experiments using exogenous cues, in which cue properties were manipulated. A dual-task set-up was used in all studies in this thesis, with a display of four random dot kinematograms containing motion and colour features. In order to examine whether endogenous attention may be spatially oriented to only one feature dimension, a central cue was presented that was 70% valid for the location of only one task. Both tasks showed validity effects, but the task for which the cue was informative showed larger attentional modulation. This suggests that spatial attention is not a single 'spotlight' but can be biased in favour of expected features. There was also asymmetry in the tasks, whereby the validity effect was modulated for motion, but comparable for colour regardless of the task for which the cue was informative. This asymmetry was also evident when using uninformative exogenous cues preceding the same tasks. Peripheral luminance and colour cues affected the validity effects for the motion and colour tasks differently, suggesting that the relationship between cue properties and proceeding stimuli modulates attentional effects. The size of a frame cue leads to different attentional effects on tasks of different sizes. These experiments make a considerable contribution to the spatial attention literature, by showing that spatial attention may be biased either by cue properties or cue information, suggesting that spatial attention and feature-based attention may interact. They also provide further evidence that motion is better represented than colour in visual attention.

Resumen

The brain selectively processes incoming sensory information and plans adequate motor output aimed at behaviourally relevant objects in the environment, based on different attentional control (AC) mechanisms. The contribution of single AC mechanisms to visual attention has been extensively investigated; still, it remains unclear how those different biasing signals interact with one another in order to reach the final choice of which spatial location (or stimulus) is worth of attention. The main goal of my PhD project was to investigate whether different AC mechanisms jointly act to shape priority of given stimuli and locations or whether, at any given moment, one mechanism prevails over the others, gaining precedence onto the neural representation of the visual space, known as spatial priority map. By using variants of the same visual search task, we implemented a series of behavioural and EEG experiments to test the unique and combined effect of two AC mechanisms: top-down control, modulated via endogenous cueing (valid vs. neutral cues), and experience-dependent control, implemented through a statistical learning (SL) protocol (high vs. low target frequency locations). Our results revealed that both cue validity and SL enhanced performance respectively for targets predicted by valid (vs. neutral) cue and for targets at high (vs. low) frequency locations. The benefit of top-down control was also confirmed by larger CNV and P1, i.e. EEG markers of general preparation and early categorization for target selection, respectively. Most importantly, when activated together, top-down control and SL display an interesting interaction, with the behavioural effect of the latter being overridden by the presence of the former. However, in terms of N2pc, an EEG index of selection, the cueing effect selectively emerged for targets in the low- (vs. high) frequency location, suggesting that, even if not behaviourally evident, the SL effect was not totally blocked by top-down guidance; rather, it could affect attentional deployment, at least at some point of the target selection process. Finally, in our tasks, we could also indirectly assess the impact of a salient distractor on individuals’ performance; this irrelevant bottom-up AC signal indeed diverted attention from the target and interfered with the task, regardless of the presence or absence of the other AC mechanisms.

Resumen

The present review discusses basic findings and current controversies regarding spatial orienting and attentional capture. Endogenous and exogenous spatial orienting and their interaction are discussed in relation to recent debates regarding the role of orienting in the preparation of eye movements, in relation to subliminal cueing, and to the debate whether spatial attention is needed for the detection of basic features. The review also discusses whether it is possible to cue a distractor location in order to reduce its effect on target processing. Stimulus-driven attentional capture and contingent capture are discussed in relation to controversies regarding non-spatial filtering, the existence of assumed search modes, and the concept of the attentional window. The review concludes that contingent capture may be nothing other than endogenous orienting.
