Concepts of psychology Flashcards
(88 cards)
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
priming
refers to a psychological phenomenon where exposure to a stimulus (in this case, a keyword) influences your response to a subsequent stimulus, such as an answer choice. In the context of examination items, a keyword that hints at the answer can act as a prime to help you retrieve the correct information.
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:
or perceptual blindness occurs when an individual fails to perceive an unexpected stimulus in plain sight, purely as a result of a lack of attention rather than any vision defects or deficits. 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).
