Materialism, Emergentism, and Structuralism in Philosophy
Monist Materialist Theories
Monist materialist theories, initiated by Democritus (5th century BC) and Epicurus (3rd century BC), were further developed in the 18th and 19th centuries by figures like Boyle, Gassendi, La Mettrie, and many others. These theories posit that mental processes can be explained solely by the material base, located in the brain.
Physicalism
Physicalism asserts that mental activities are simply physical, chemical, or neurophysiological processes. This view is shared by 20th-

Brain Structure and Function
Cerebral Cortex
The cerebral cortex is the outer layer of the cerebral hemispheres, containing 70% of neurons in the CNS. It is composed of five layers of neurons and a plexiform layer (composed of fibers). The convolutions of the cortex allow the large cortical surface to fit a small space.
- Grooves: Channels or grooves
- Fissures: Deeper grooves
- Convolutions: Deformations produced by the folds
Cerebral Hemispheres
Left Hemisphere
The left hemisphere controls logical functions

Institutional Informants
Institutional informants are valuable because their informal ties can provide insights into the everyday reality of the institution. Researchers should be cautious not to be unduly influenced by their opinions.
Coexistence and Social Relations in the Field
The preliminary design should include logistical considerations, such as the observer’s residence. If there’s doubt about the impact of the observer’s accommodation, a hotel or temporary residence is preferable. In closed

Child Development Through Play
Sensory Period (0-2 Years)
The child begins to develop the ability to play. Play reflects an activity stimulated by sounds, colors, movements, and textures. Play is a fundamental sensory-motor pleasure. It is characterized by repetition, practice, exploration, manipulation, and touching of sensitive areas. The receiver (sucks, touches, smells, looks, handles) is attracted to toys.
Preoperational Period (2-7 Years)
Repeated actions become habitual and are then projected

Phases of Learning
Cognitive Phase
In the cognitive phase, a greater number of errors is common. There is not much fluidity of movement or accuracy. There is a cognitive abstraction. The teacher is responsible for making the student identify the purpose of the activity and environmental conditions. This phase has a variable duration.
Associative Phase
The associative phase involves greater motor refinement. Fewer errors occur, and frequent errors are eliminated. Greater fluidity and movement coordination

Primary Progressive Aphasia
Primary progressive aphasia (Measure 82) is characterized by an insidious alteration of language due to atrophy in the left perisylvian areas, in the absence of dementia. It involves a progressive loss of language that takes at least two years to develop. After these two years, cognitive symptoms appear. There are two types: fluent and nonfluent. It begins as aphasia and then progresses to dementia.
Manifestations
- Increased phonological errors
- Reduced
