“…More informative in this respect is a recent series of visual search studies in which observers were cued on each trial as to what to look for, with the same cue then being repeated for a number of trials (Carlisle, Arita, Pardo, & Woodman, 2011;Gunseli, Olivers, & Meeter, 2016Reinhart & Woodman, 2014;Schneider, Bonmassar, & Hickey, 2018;van Moorselaar, Theeuwes, & Olivers, 2016;Woodman, Carlisle, & Reinhart, 2013). In a seminal study, Carlisle et al (2011) measured EEG activity while observers performed a visual search for a specific Landolt-C target among similar Landolt-C distractors.…”

Visual attention serves to select relevant visual information. However, observers often first need to find out what is relevant. Little is known about this information-seeking process and how it affects attention. We employed a cued visual search task in combination with eye tracking to investigate which oculomotor measures reflect the acquisition of information for a subsequent task. A cue indicated as to which target to look for in a following search display. Cue-target combinations were repeated several times, enabling learning of the target. We found that reductions in cue fixation times and saccade size provided stable indices of learning. Despite the learning, participants continued to attend to repeated cues. Several factors contribute to people attending to information they already know: First, the information value provided by the cue continues to drive attention. Second, even in the absence of information value, attention continues to be directed to cue features that previously signalled relevant information. Third, the decision to attend to a known cue depends on cognitive effort. We propose that this combination of information value, previous relevance, and effort is best captured within an information-seeking framework, and that oculomotor parameters provide a useful proxy for uncovering these factors and their interactions.

“…Reward incentives have been shown to reduce saccadic response times and distraction e.g. 127 , enhance target detection sensitivity in exogenous 128 and endogenous 129 spatial cueing tasks (see also 130,131,132 ), and speed responses in visual search 119,[133][134][135] . Furthermore, rewards have been shown to modulate the effects of inter-trial priming [136][137][138][139][140] and statistical learning 132,141 .…”

Dissociating neuronal signatures of spatial attention and behavioural state in the primary vibrissal cortex of mice

The prioritisation and selective processing of information is imperative to survival. One form of prioritisation, known as spatial attention, allows an animal to selectively process sensory input based on its location. While spatial attention is known to produce changes in neuronal representation, it is unclear whether these changes occur as early as the primary sensory cortex. It is also not clear whether changes induced by selective spatial attention differ from those observed with non-selective fluctuations in arousal. To study attention, the rodent whisker system represents a structurally elegant, and functionally efficient alternative to the often-studied primate visual system. Here, we implemented a novel, ecologically relevant paradigm to incorporate spatial attention in a whisker vibration detection task in mice. We demonstrated that mice (n = 11) exhibit spatially selective evidence accumulation behaviour within their responses to single vibration stimuli, across their responses to tens of stimuli, and throughout each day of training. To dissociate the neuronal signatures of spatial attention from those of spatially non-specific behavioural state, we recorded 1461 responsive neurons in the primary vibrissal cortex (vS1) as mice engaged in the detection task. The strength of neuronal responses to vibrissal stimulation correlated significantly with spatial attention, but not with spatially non-specific behavioural state. We found that spatial attention elevates both baseline neuronal activity and a later (200–600 ms) component of evoked responses to whisker vibrations. These results have implications for the microcircuitry of spatial attention in vS1 and value-driven attentional capture in mice.

“…For example, a CDA amplitude was present in a change‐detection task when the objects remained within view, so without any retention interval (Tsubomi et al, 2013). Moreover, the CDA was present in visual search tasks, multiple objects tracking (MOT) tasks, temporal chunking, and grouping tasks (Akyürek et al, 2017; Balaban & Luria, 2020; Drew et al, 2011; Drew et al, 2018; Hilimire et al, 2011; Luria & Vogel, 2011; Poncet et al, 2016; Reinhart et al, 2016; Reinhart et al, 2019; Schneider et al, 2018; Williams & Drew, 2020). In all these examples, the CDA was observed without a retention interval, as long as VWM was involved.…”

One turn at a time: Behavioral and ERP evidence for two types of rotations in the classical mental rotation task

We perform mental rotations in many everyday situations, such as reading a map or following furniture assembling instructions. In a classical mental rotation task, participants are asked to judge whether a rotated stimulus is presented in its mirrored form or its canonical form. Previous results have indicated a degree effect: RT is longer as the angle of rotation increases, and this effect is traditionally explained by arguing that this judgment requires rotating the stimulus back to its upright form. Importantly, in half of the trials, the stimuli are rotated on both the page plane and mirror plane. Namely, we argue that in previous research the task actually involved two different rotation processes. To provide a clear dissociation between these two rotations, we collected EEG data and used the Contralateral Delay Activity (CDA) as an indicator of visual working memory (VWM) load. The results of Experiment 1 suggested different VWM involvement according to the degrees rotations when the item was not mirrored, such that the CDA amplitude generally increased as the degree of rotation was higher. Mirrored trials were all at ceiling in terms of CDA, regardless of their rotation degree. Experiment 2 showed increased CDA amplitude uniquely related to the flip rotation. Thus, we provided ERP evidence that the canonical mental rotation task involves two types of rotations that can be dissociated based on the load they imposed on VWM.
