Basic psychology

The form of language

Language forms include dialogue language, monologue language, written language, sign language and internal language.

The Central Nervous Mechanism of Language

The left hemisphere of the brain is responsible for language.

① Blocker District

Located in the left inferior frontal gyrus of the brain, if damaged, it will lead to motor aphasia and dysphonia.

② Wilnick district

Located in the posterior part of the superior temporal gyrus in the left hemisphere of the brain, it is in charge of the understanding of speech meaning.

③ angular gyrus

Located at the junction of parietal lobe and frontal lobe, it is responsible for the conversion of spoken and written language.

language understanding

definition

Language understanding is a process that involves auditory or visual language materials and actively constructs meaning in the brain.

(1) Speech Comprehension (by means of listening)

Speech comprehension begins with speech perception, also called speech perception, which is a process of recognizing speech.

1. Physical characteristics of speech

? Tone: refers to the level of sound, which is related to the frequency of sound waves. Depending on the length, thickness and tightness of the vocal cords.

Sound intensity: the strength of speech is related to the amplitude of sound waves.

? Timbre: The timbre of speech is related to the waveform of sound waves.

? ? Sound length: the sound length is related to the vibration time.

2. Factors affecting speech comprehension

Speech intensity, speech similarity, noise masking, context.

(2) Reading comprehension (with the help of vision)

1. Vocabulary understanding

influencing factor

① letter length and number of strokes

② Location information and font structure of words.

? The first and last letters of words play an important role in recognition.

Chinese characters with left and right structures are easier to identify.
