Concepts of psychology Flashcards
Psychology
is a scientific and
systematic study of individuals’
mental processes, behavior, and
experience in natural or nurtured
conditions
perceptual processes.
People experience the external environment through
Sensory receptors
(e.g., eyes, ears, skin) convert stimulus energy into neural signals and transmit them to the brain (steps 2–4).
Perception
follows sensation: it is the interpretation of stimuli received by sensory organs
Action
is the physical response to environmental stimuli (steps 5–6).
Sensation
collecting signals from the environment.
visible spectrum
is limited to wavelengths between 400 and 700 nanometers (Gerrig et al., 2015).
Memory
is viewed like a computer that receives, stores, encodes, and retrieves information
Long-term memory
Stores information permanently with relatively unlimited capacity
Chunking
A technique for increasing STM capacity by grouping information into meaningful units
Recency effect
Recently presented information is remembered better than earlier information
Spaced repetition
Involves extending review periods over time to reinforce memory
Attention
Focused awareness of available perceptual information. It plays a crucial role in processing stimuli from the external environment (e.g., noticing your name in a loud room, a phenomenon known as the cocktail party effect).
Split-attention effect:
The brain processes visual and auditory information through separate channels. Focusing on multiple information sources simultaneously can increase cognitive load and harm learning effectiveness (Ayres & Sweller, 2005).
Figure-ground perception:
The ability to focus on objects while distinguishing them from the background (e.g., seeing a tree or faces depending on perception).
Selective attention
allows people to focus on a specific task while filtering out irrelevant stimuli (e.g., reading in a noisy environment).
Inattentional blindness:
Inattentional blindness:
Problem-solving
is the cognitive process of moving from an unsatisfactory condition to a desired state using optimal strategies
principle of transformation
stimuli and responses created by stimuli are transformed, or changed between the environmental stimulus and perception
Behaviorism
Focuses on observable behavior influenced by external stimuli. Key figures: Pavlov, Skinner, Watson.
Cognitivism & Constructivism:
Emphasize active knowledge construction. Key theorists: Vygotsky (social learning), Harel & Papert (constructivism).
constuctivism
Learners actively construct knowledge through experience (Vygotsky, 1978; Schunk, 2012).
Emphasizes meaningful learning shaped by social and cultural contexts (O’Donnell, 2012).
classical conditioning
Pavlov’s experiment with dogs illustrates how pairing stimuli can lead to conditioned responses (Clark, 2004).
operant conditioning
Skinner’s experiments show how behavior is shaped through reinforcement and punishment (Gerrig et al., 2015).
social learning theory
Learning occurs through observing and imitating others (Bandura & Walters, 1977).
Intelligence
General competence involving thinking, reasoning, and problem-solving (Gottfredson, 1997).
Intelligence is influenced by cultural and environmental factors (Neisser et al., 1996).
positive reinforcement
The presence of a pleasant stimulus is increased, such as receiving rewards.)
positive punishment
The future response is followed by an unpleasant stimulus, such as pain and getting caugh
negative reinforcement
The presence of an unpleasant stimulus is decreased, such as using a fan to escape the heat.)
negative punishment
The future response is followed by removing a wanted stimulus, such as no dessert when refusing to eat carrots.)
Intrinsic motivation
Motivation driven by internal factors like personal interests, enthusiasm, and curiosity.
Examples: Playing football for the sheer joy and excitement of the game or engaging in a hobby because it is personally fulfilling.
Maslow’s Hierarchy of Needs
A motivational theory that explains human behavior as driven by a hierarchy of needs.
Needs are arranged in a pyramid, starting from the most basic physiological needs to self-fulfillment needs.
Physiological Needs
Basic needs essential for survival: food, water, sleep, warmth, and air.
These needs must be met before individuals can focus on higher-level needs.
Example: Seeking food and shelter when hungry or tired.
Safety Needs
Needs related to security and protection: personal safety, financial security, health, and well-being.
Example: Desiring a safe living environment or a stable job.
