Types of memory: -The specific; -The individual. -The short-term; -The long-term; -The mechanical; -The logical; -The touch; -The emotional.
Memory consists of 3 processes: 1. -Storing; 2. -Preservation; 3. -Reproduction. Memory levels: 1. -The reproducing – the highest level; 2. -The identifying; 3. -The facilitating.
Memory theories 1. Conditioned-reflex; 2. Theory neural models; 3. Associative; 4. Chemical;
Dream – a condition of an organism which is characterized by considerable decrease in all functions of an organism, partial shutdown of consciousness. Types of a dream: 1. Physiological dream: - polyphase dream at children; - monophase dream at adults; - seasonal dream; 2. Hypnotic dream. 3. Pathological dream: - narcotic dream; - somnambolizm (sleepwalking); - lethargical sleep.
The physiological dream consists of two alternating phases: - slow or orthodox dream: REM or paradoxical sleep (15 -20%).
Dream stages: 1. Somnolence - disappearance a rhythm alpha, 1 -7 min. 2. Emergence of sleepy spindles on EEG – to 50% of a dream. 3. Emergence delta flounce, 20%. 4. Paradoxical dream – a beta a rhythm, flashes an alpha of a rhythm, BDG.
Dream theories: 1. Humoral; 2. The theory of the poured braking of Nominative of Pavlov. 3. V. Gess's theory. 4. Theory of information deficiency.
Dreams – always accompany a dream and are more often connected with a phase of a paradoxical dream. I. M. Setchenov characterized them as "unknown combinations of skilled impressions".
Emotion (I induce, I excite) – a physiological condition having in pronounced subjective coloring, is a component of motivations. Distinguish concepts: 1. Emotional stress. 2. Affect. 3. Mood. Classification of emotions: 1. Positive, negative; 2. The highest, the lowest. 3. Sthenic, asthenic.
Emotion theories: 1. C. Darvina's theory (instinctive action); 2. P. K. Anokhin's biological theory. 3. P. V. Simonov's information theory. Э = П (requirement) x (Ying – Is); Ying – necessary information, Ис – existing information. 4. G. I. Kositskogo's theory. Э = C (Ying En Vn – Is Es Vs) Ying En Vn – necessary information, energy, time Is Es Vs – existing information, energy, time. 5. Central theory. 6. Korkovo – the subcrustal theory.
Motivations are the emotionally painted aspirations of the person and animals to satisfaction of leading requirements. Motivations leads to purposeful search behavior. Interests – emotional manifestation of informative need of the person. Types of motivations: 1. The lowest (biological, vitalny). 2. The highest: - the social. - the ideal.
