Sensation pt 2

Flashcards summarizing key concepts from the PSYC100 lecture on psychology research methods, brain functions, memory systems, and case studies.

Experimental Design

A research method that manipulates an independent variable to observe the effect on a dependent variable.

Correlational Design

A research method that assesses the relationship between two variables without manipulating them.

Descriptive Design

A research method that provides a detailed account of the subjects’ characteristics or behavior without influencing them.

Case Study

An in-depth examination of a single individual or group to explore complex issues in real-life contexts.

H.M. case study

A significant study on memory, where patient H.M. had parts of his brain removed affecting his ability to form new explicit memories.

Phineas Gage

A famous case that provided insight into the relationship between brain injury and personality changes; he survived an accident that damaged his frontal lobe.

Frontal Lobe

The brain region responsible for thought, planning, and movement.

Parietal Lobe

The brain region responsible for touch and spatial relations.

Temporal Lobe

The brain region associated with hearing and memory.

Occipital Lobe

The brain region responsible for vision.

Epigenetics

The study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself.

Atkinson and Shiffrin's Memory Systems

A model of memory that includes sensory memory, short-term memory, and long-term memory.

Sensory Memory

A type of memory that holds information for a brief moment, where unattended information is lost.

Short-term Memory

A type of memory that holds unrehearsed information for a limited time.

Long-term Memory

A type of memory that has a potentially unlimited capacity over a long duration.
