eg When reading a novel, you turn a blind eye to everything happening around you.

No booking purpose, poor consciousness, short retention time

stimulus intensity

Exciting novelty

The contrast of stimuli eg a little green among thousands of flowers

changes in stimulus activity

People's subjective psychological state eg things that meet people's needs and direct interests

Have a clear purpose

Have strong willpower

Deepen understanding of purpose tasks

Organize activities reasonably, e.g. use performance method for class content

Compliance with interests, e.g., direct interest is cultivated in higher grades, and indirect interest is cultivated in lower grades.

Check for interference from internal and external factors

Have a strong interest in activities

Automation of activities

Characteristics of objects: Objects that have practical significance and are easy to be understood will have a larger scope of attention; otherwise, the scope of attention will be smaller. The arrangement is regular and can form an interconnected whole, with a larger scope; otherwise, it will be smaller.

individual experience and knowledge

How to grasp objects

individual's emotional state

Perceptual tasks, such as editing tasks and people engaged in proofreading tasks, the attention span of the former is larger, while the attention span of the latter is smaller.

Pay attention to the time you stay on a certain object

Focus on a certain activity and change the specific objects of attention as the activity progresses

The subjective state of the individual: the deeper the understanding of the activity, the more positive the attitude, the stronger the interest, and the more stable the attention.

Characteristics of attention objects: The richer the content, the more lively and diverse the activity forms, and the higher the stability of attention.

Pay attention to ways and means

1. When only one of the various activities is unfamiliar and the rest of the activities have reached "automation" or semi-automation, attention can be better allocated to these activities.

2 There are close relationships between several activities

3 Have skilled distribution skills

1. Shifting requires purposefully turning attention to a new object, while dispersion involves diverting attention away from the object to be paid attention to when concentration is required.

2. Diversion is a good quality of attention, and distraction is a bad quality of attention.

It turns out that the smaller the intensity of attention, the easier it is to transfer; vice versa.

Characteristics of new attention: If the new object of attention meets people's needs and interests, it will be easy to transfer; vice versa.

The flexibility of mutual conversion between neural excitation and inhibition processes in the cerebral cortex. People with high flexibility can transfer more easily.

The purpose of each activity or the conditioning effect of the secondary number system. The purpose is unclear, the adjustment ability is weak, and the transfer is inflexible.

The purpose of attention of primary and secondary school students continues to increase

********* The stability continues to increase, and the growth rate gradually slows down in high school.

Relatively speaking it is much slower

The greater the intensity of stimulation, the easier it is to attract unintentional attention

The more significant the difference between stimuli, the more likely it is to attract unintentional attention.

Changes in stimuli: moving ones are more likely to attract unintentional attention than static ones.

Novelty of the stimulus: Novel stimuli are more likely to attract unintentional attention than familiar stimuli.

An individual's subjective state, needs and interests

Understanding of activity tasks. The clearer the task, the better it can attract and maintain intentional attention.

The stronger the indirect interest in the activity, the more concentrated it is.

individual volitional effort

Careful organization of activities

Strong interest in activities

Automation of activities Cycling

1 Understand the students’ listening status based on the external manifestations of attention

2. Use unintentional rules to organize teaching activities

3 Organize teaching activities using the rules of intentional attention

4. Organize teaching activities using the law of alternation between unintentional and intentional attention.
