Study Notes

Memory

Memory is the process by which information is encoded, stored, and retrieved.
Encoding involves converting sensory information into a neural code that the brain can process and store.
Storage refers to the retention of encoded information over time.
Retrieval involves accessing stored information and bringing it into conscious awareness.
Different types of memory systems exist, including sensory memory, short-term memory, and long-term memory.
Sensory memory holds information briefly, less than a few seconds, and is crucial for maintaining awareness of our immediate surroundings.
Short-term memory (STM) holds information for a few seconds to minutes, and has limited capacity. It is also known as working memory, as it plays a role in manipulating and processing information.
Long-term memory (LTM) stores information relatively permanently and indefinitely. It has a vast capacity.
LTM can be further subdivided into explicit (declarative) memory and implicit (non-declarative) memory.
Explicit memory involves conscious recollection of facts and events (episodic and semantic memory).
Implicit memory involves unconscious influences on behavior; this includes procedural, priming, and classical conditioning.
Factors affecting memory include attention, motivation, emotional state, and prior knowledge.
Forgetting can result from various factors, such as decay (storage failure), interference (new or old information interfering with recall), or retrieval failure (difficulty in accessing stored information).
Techniques to enhance memory include mnemonics, repetition, and elaborative rehearsal.

Perception

Perception is the process by which sensory information is organized and interpreted.
It involves the detection, selection, and organization of sensory stimuli into meaningful patterns.
Bottom-up processing involves processing sensory information from the stimulus itself, whereas top-down processing involves prior knowledge, expectations, and context in interpreting sensory stimuli.
Perception is influenced by factors such as attention, motivation, expectations, and cultural background.
Different sensory modalities (vision, hearing, touch, taste, smell) each have distinct mechanisms and characteristics, but they share processing patterns.
Visual perception involves processing light patterns to produce a representation of the world, including depth perception, shape recognition, and object recognition.
Auditory perception involves processing sound waves to identify different sounds, including pitch, loudness, and timbre.
Touch perception involves receiving information about pressure, temperature, and pain; these sensations help determine the properties of objects.
Taste perception involves detecting various tastes through taste receptors located on the tongue; and smell perception involves detecting various airborne molecules that stimulate olfactory receptors.

Development

Development is a systematic process of growth and change over the lifespan.
Development encompasses physical, cognitive, and psychosocial changes.
Physical development refers to changes in the body's structure and function.
Cognitive development involves changes in thinking processes, language abilities, and problem-solving skills.
Psychosocial development refers to changes in social interaction, relationships, emotions, and personality.
Developmental theories propose frameworks to understand the patterns and processes of development, including Piaget's stages of cognitive development, Erikson's psychosocial stages, and Vygotsky's sociocultural theory.
Research on human development has implications for education, healthcare, social policy, and parenting practices.

Research Methods

Research methods are systematic procedures used to study a phenomenon or test a hypothesis.
Research methods can be broadly categorized as qualitative and quantitative.
Qualitative research methods focus on in-depth understanding and description of a phenomenon. Techniques used include observations, interviews, focus groups, and case studies.
Quantitative methods focus on numerical data collection and analysis to test hypotheses and draw generalizations. Techniques used include surveys, experiments, and correlational studies.
Experimental research involves manipulating one or more independent variables to observe their effect on a dependent variable, while controlling for other potential factors.
Correlational research examines the relationships between two or more variables without manipulating them; it aims to determine the degree of association between the variables, and not causation.
Observational research involves systematic observation of behavior in natural or controlled settings.
Surveys involve collecting data from a large sample of participants using questionnaires or interviews.
Case studies involve in-depth investigation of a single individual, group, or event.
Validity and reliability are crucial considerations when evaluating research findings. Validity refers to the extent to which a study measures what it intends to measure, whereas reliability refers to the consistency of the findings.
Ethical considerations are essential when conducting research, focusing on minimizing harm to participants and ensuring informed consent.
Replication is essential to verify the findings of a research study.
