What is space based model of attention?

Space-based attention is a process that allocates attention to a specific region, or location(s), in the visual field, whereas object-based attention directs attention to coherent forms or objects in visual space.

What is spatial attention in psychology?

Spatial attention involves selecting a stimulus on the basis of its spatial location. The region occupied by the item is selected and then receives further cognitive processing (eg, the item might enter visual working memory or become the target of a movement).

What is location based attention in psychology?

Location-based attention is indicated by the spatial-cueing effect, a shorter reaction time (RT) when the target appears at the cued location than at the uncued locations, whereas object-based attention is indicated by the same-object advantage, a shorter RT when the target appears at the uncued end of the cued …

What is object-based attentional failure?

Lamy and Egeth found object-based attentional effects when attentional shifts during tasks were required, but no attentional effects when the shifts were not required. Attentional shifting theorises that the cost of switching between objects, rather than within objects, occurs due to three individual components.

What is visuospatial orienting?

Attention is the process by which we select stimuli in our environment for perception and action. The ability to orient to salient visual stimuli and to parse the visual world begins to emerge in the first few months of life and continues to evolve through childhood.

What is visuospatial attention?

Visuospatial attention is the capacity of someone to attend to and to process stimuli in his surrounding space (Posner and Petersen, 1990). The interaction between the allocentric and egocentric visuospatial representations allows for spatial processing.

What is the difference between endogenous and exogenous attention?

The ability to focus attention is a central feature of human cognition. Goal-driven attention is referred to as top-down or endogenous attention, whereas stimulus-driven attention is referred to as bottom-up or exogenous attention, being driven by external events in the environment (e.g., Posner & Cohen, 1984).

What is attentional warping?

attentional warping. brain changes to allow more space for what is being searched for. automatic processing. understanding which occurs without intention and while using only some of a person’s cognitive resources.

What part of the brain controls visuospatial?

In humans, he parieto-occipital region is believed to process visuospatial and visual motion types of information. Whereas, the inferotemporal region of the brain is believed to mediate our ability to process visual information about the form and color of objects.

What is spaced-based attention?

SPACE-BASED ATTENTION: “Spaced based attention is towards spatial locations rather than the objects.”.

What is the difference between space based and object based attention?

SPACE-BASED ATTENTION. attention towards spatial locations rather than the objects. Compare object based attentions. SPACE-BASED ATTENTION: “Spaced based attention is towards spatial locations rather than the objects.”.

What triggers space-based attention?

Space-based attention may be triggered by salient stimuli in the visual field (e.g. an onset of light, a great sensory change, appearance of a new object) (see Ruz & Lupiañez, 2002; Yantis, 2000, for recent theoretical and empirical reviews of the literature on attentional capture).

What is visual spatial attention?

Visual spatial attention is a form of visual attention that involves directing attention to a location in space.
