Questions related to Visuospatial Attention
Is there an actual proof that visual-spatial cues enhance early or late visual processing (as compared to uncued visual processing)?
Without saying that what is implied by this question is "true", we know that when it comes to response times (RT), peripheral (or exogenous) and central (or endogenous) cues will have a different impact (e.g., Doallo et al., 2004). However, I struggle to find any event-related potentials (ERP) study that demonstrates an enhancement of perceptual processes following a cue (preferably peripheral) when compared to "self-generated", or spontaneous, gazes (i.e., overt spatial attention).
For instance, say that you have to look out for forest fires all day long. You will probably end up doing something else to fight boredom, and hence end up looking for possible smoke from time to time.
Now the question is: Will you be able to report(RT) a smoke faster if you are spatially cued because the cue allowed you to perceive(ERP) it faster?
Endogenous Cue – Spontaneous = ?
Exogenous Cue – Endogenous Cue = ?
Exogenous Cue – Spontaneous = ?

Memory components in MANNs are pretty basic. I know of models with multiple attention components. Are there Deep Learning (DL) architectures that employ a multiple-component approach for memory as in Baddeley & Hitch, 1974 and Baddeley, 2000?
I know some studies which show that stimuli considered as phylogenetically fear-relevant, such as snakes or spiders, benefit of a greater attentional capture than other stimuli, even for babies. I would like to know if some studies have investigated this effect with stimuli considered as ontogenetically fear-relevant, such as guns, in a young population without experience of those stimuli (babies ?).
the protocol is somewhat like that- 2 set size was applied (12 and 16) in each set size 1 is target and remaining are the distractors. Total sets of trials 16- 8 with target present and 8 without target. I have used the eye tracking technique to assess the visuospatial attention while performing the visual search. What element of the eye tracking data will be useful to interpret the scenario ?
I am looking for research on spatial memory, but not on the scale of cities or buildings (spatial navigation), but rather a small scale spatial memory of objects in a room, hall or even just on a workbench.
Preferably done in a real world setup and not on desktop. Possibly also done in VR (rather on HMD than just desktop VR. could also be CAVEs).
How can one define visuo-spatial working memory capacity of subjects reporting a continuous value? Subjects are shown a set of stimuli and after a given delay, they have to report using a cursor where one of the stimulus was shown. I'm aware of this kind measure for discrete reports, but I guess those are not useful here.
Thank you in advance,
I would like to create an experiment which can be shared on internet (like Facebook for exemple).
But the experiment that i want to built needs accurate presentation time (my faster frame is 25ms) and i need to collect accurate reaction times (around 1/2ms of accuracy).
Is there a software or a website that can do that ?
Ask for advice: Comparing the delay or retrieval activity in object color-based working memory with corresponding activity in object location-based WM.
I would be grateful if someone could give me some advices and paper.
According to the literature, caffeine affects on cognitive performance (memory, attention, etc.). Also, the location of attention focus may affects postural stability. Now, what is the best research design or protocol to assess the effects of caffeine and attention focus on postural control?
I made a study with two types of targets (3 shematic faces or 3 schematic houses). The task where participants had to detect the 3 schematic houses and ignore distractors (photo of houses or faces) seems to be more difficult (reaction time bigger, more false alarms) than the task where participants had to detect the 3 shematic faces.
As the heterogeneity of the 3 schematic houses is more pronounced than the heterogeneity of the 3 schematic faces, i wanted to know if some studies have investigated the impact of the heterogeneity of the target on attentional capture by distractors ?
Or are general tests for dementia administered such as the MMSE and MoCA? I am interested in all tests that measure cognitive function, but particularly visual attention.
I believe some metrics related to the eye, such as pupil dilation, may give an indication of the extent to which something being looked at is being actively processed. However, I am interested in ways to determine whether someone is paying attention to (cognitively processing) what they are looking at in natural, real-world conditions, where changing light levels may make it difficult to use pupil dilation as a measure. I am therefore wondering if there are any tell-tale signs from eye movements that can reveal whether something is being actively processed and has some cognitive importance to the observer.
For example, research on inattentional blindness shows that just because something in our environment is fixated does not mean it is perceived or processed. Also, research has been carried out about mind-wandering during reading which suggests eye movements may be qualitatively different during periods of mind-wandering compared with when what is being read is being processed. Are there any similar findings for natural situations such as just walking through an environment?
We know, for example, that some action games and mathematics can be capable of developing these skills. What other activities can?
Based on the “Object-Spatial-Verbal Cognitive Style Model” from Kozhevnikov, Kosslyn and Shephard (2005), Are there any available instruments to measure the visuospatial dimensions (Object imagery – ability to mentally represent object details like form, color, etc; and Spatial Imagery – ability to mentally represent and manipulate spatial relations between objects and its parts) separately?
Any tips will be welcome, thank you!
