What causes inattentional blindness?

Inattentional blindness occurs when there is an interaction between an individual’s attentional set and the salience of the unexpected stimulus. Recognizing the unexpected stimulus can occur when the characteristics of the unexpected stimulus resembles the characteristics of the perceived stimuli.

What are the 3 steps that are basic to all our sensory systems?

All our senses perform three basic steps: They receive sensory stimulation, transform that stimula- tion into neural impulses, and deliver the neural information to our brain. The process of convert- ing one form of energy into another that our brain can use is called transduction.

How is attention related to perception?

Think of attention as a highlighter. Not only does our attentional system allow us to focus on something specific in our environment while tuning out irrelevant details, but it also affects our perception of the stimuli surrounding us.

What are the 4 types of attention?

Selective attention is the ability to select from many factors or stimuli and to focus on only the one that you want while filtering out other distractions. Divided attention is the ability to process two or more responses or react to two or more different demands simultaneously.

What is involuntary attention?

Involuntary attention in this contribution refers to the processes of attending that are not elicited by intentions but by certain outside events. The discussion is fully limited to specific processes of attending, elicited by the deviation of stimulus events from a given context.

What is the difference between voluntary and involuntary attention?

Voluntary attention is the type of attention that is goal-directed and determined by the relevant task at hand. Involuntary capture of attention results when stimuli are selected due to saliency rather than to task relevance (Jonides, 1981).

What is volitional attention?

Volitional (Voluntary Attention): Volitional attention exercises the will and demands our conscious effort for arriving at a solution or achieving certain goals. This kind of attention does not depend on the stimulus but depends essentially on the attentive capabilities of an observer.

What is reflexive attention?

Reflexive attention is essentially a semi-autonomous decision making system. Goals can influence what kinds of stimuli will be able to trigger attention, but the actual decision to deploy attention is linked to the onset of a physical stimulus.

What is the spotlight theory of attention?

According to the spotlight theory of visual attention, people can attend to only one region of space at a time Eriksen and St James 1986, Posner et al. 1980. People can shift their spotlight of attention from location to location, independent of eye position, and adjust the size of the attended region like a zoom lens.

What is attentional selectivity?

Selective attention is the process of focusing on a particular object in the environment for a certain period of time. Attention is a limited resource, so selective attention allows us to tune out unimportant details and focus on what matters.

How can I increase my selective attention?

What is alternating attention?

What distributed attention?

The concept of distributed attention is based on the conceptual apparatus of perceptual psychology: it is attention that is focused on one perceptual object but distributed across various properties of this object.
