The human brain

Cerebral Cortex

Reception of spoken and written language

Brain Hemispheres
7
Cerebral Hemispheres Broca’s area (Paul Broca) Wernicke’s area (Carl Wernicke) Frontal lobe, above the Sylvian fissure Between the parietal and the temporal lobe, below the Sylvian fissure Production of grammatically correct sentences; high level syntactic structures; native intonation Understanding and comprehension of spoken language; comprehension and production of meaning Connected by corpus collusumw
8
Right hemisphere Processes Creativity, patterns, spatial awareness and context; awareness of second language learning; dominance for procession of intonation (Sheila Humstein) Functions Connected to left side of the body Processes information more diffusely and simultaneously Responsible for relational and mathematical operations Specializes in recognizing places, faces, objects, and nonverbal skills—music, visual, functions, artistic ability Responsible for emotional and social needs; the seat of passion and dreams Responsible for gestures, facial movements, and body language understanding and remembering things we do and see putting bits of information together to make an entire picture
9
Processes Speech, analysis, time, sequence Functions Responsible for language acquisition and ability to speak languages; Processes information in a linear and sequential manner Responsible for verbal expression, language functions and capacity to use language meaningfully; Responsible for invariable and arithmetic operations; Specializes in recognizing words and numbers; Does logical and analytical thinking; memory for spoken and written messages; detailed analysis of information. Left hemisphere

Aphasias Yes... ah... Monday... er... Dad and Peter H... (his own name), and Dad.... er... hospital... and ah... Wednesday... Wednesday, nine o'clock... and oh... Thursday... ten o'clock, ah doctors... two... an' doctors... and er... teeth... yah I called my mother on the television and did not understand the door. It was too breakfast, but they came from far to near. My mother is not too old for me to be young
11
Aphasia loss or impairment of the ability to produce and/or comprehend language, due to brain damage languagebrain damage

13
Brain Lateralization Specialization of the functions of each cortical hemisphere as the brain matures Krashen, 1973, lateralization is complete by age five; Lenneberg, 1967, around pubertyñ Scover, 1984), emergence of lateralization at birth, quite evident at five, and completed, only evident, at about puberty. Biologically determined period of life when language can be acquired more easily and beyond which time language is increasingly difficult to acquire Critical Age Hypothesis

15
Left Hemisphere: Broca’s and Wernicke’s areas, central role in language functions
16
Spatial separation in Broca’s area in late bilinguals
20
Activity of Wernicke’s area in early bilingual
21
Activity in Brodman’s 44 in late bilinguals
22
Activity in Wernicke’s area in late bilinguals
23
Overlapping in activation of Broca’s area in early bilinguals
27
First vs second languages and the role of Broca’s area
28
Cognitive growth is an essential synergy in human development
30
Higher level cognitive processes Using critical thinking exercises extends the child’s ability to read, think, reason, and process information in a more coherent and clear way The higher the level of thinking, the more abstract and complex the task is
31
Cognitive skills encompass different types of processes: Classifying Discriminating between real and fantasy/make-believe, between fact and opinion Distinguishing abstract from concrete, true and false Summarizing, outlining
32
Comparing and contrasting Identifying structure, steps in a process, parts of a story, relationships Identifying main ideas Ordering objects (facts, ideas) Estimating Predicting, inferring
