Midterm Vocab Review Flashcards
Case study
An in depth investigation of an individual subject
Cross sectional study
Researchers compare the differences and similarities among people in different age groups at a given time
Halo effect
Phenomenon that occurs in self reports when someone’s overall evaluation of a person, object, or institution spills over to influence more specific ratings
Meta-Analysis
A research technique that combines the statistical results of many studies of the same question, yielding an estimate of the size and consistency of a variables effects
Reactivity
Alteration of a subjects behavior due to the presence of an observer
Control group
Subjects in a study who don’t receive the special treatment given to the experimental group
Experiment
A research method in which the investigator manipulates a variable under carefully controlled conditions
Independent Variable
In an experiment, a condition / event that a researcher varies in order to see its impact on another variable
Operational Definitions
In empirical research a definition that describes the actions or operations that will be used to measure / control a variable
Sample
The collection of subjects selected for observation in an empirical study
Correlation
2 variables are related
Experimenter Bias
Phenomenon that occurs when a researchers expectations or preferences about the outcome of a study influence the results
Journal
A periodical that publishes technical and scholarly material, usually in a narrowly defined area of inquiry
Placebo effect
Subjects expectations lead them to experience some change even though they didn’t receive treatment
Social Desirability Bias
A tendency to give socially approved answers to questions about oneself when responding to surveys
Correlation Coefficient
A numerical index of the degree of relationship between 2 variables
Extraneous variables
Any variables other than the independent variable that seem likely to influence the dependent variable in a specific experiment
Longitudinal study
A group of subjects are observed at intervals over an extended period of time
Random assignment
A procedure in which all subjects in a study have an equal chance of being assigned to any group / condition
Theory
A system of interrelated ideas that is used to explain a set of observations
Adaptation
An inherited characteristic that increases in a population because it helped solve a problem of survival / reproduction during the time it emerged
Corpus Callosum 🧠
The major structure that connects the 2 cerebral hemispheres
Fitness
The reproductive success of an individual organism relative to the average reproductive success of the population
Lesioning
Destroying a piece of the brain
Neurotransmitters
Chemicals that transmit information from one neuron to another
Afferent Nerve Fivers
Axons that carry information inward to the central nervous system from the periphery of the body
Critical period
A limited time span in the development of an organism when it’s optimal for certain capacities to emerge because the organism is especially responsive to certain experiences
Forebrain 🧠
The largest and most complicated region of the brain, encompassing a variety of structures, including the thalamus, hypothalamus, limbic system, and cerebrum
Limbic System 🧠
A loosely connected network of structures roughly located along the border between the cerebral cortex and deeper subcortical areas
Pituitary gland 🧠
The master gland of the endocrine system. It releases a great variety of hormones that can put through the body, stimulating actions in the other endocrine glands
Cerebral cortex 🧠
The convoluted outer layer of the cerebrum
Efferent nerve fibers 🧠
Axons that carry information outward from the central nervous system to the periphery of the body
Hormones
The chemical substances released by the endocrine glands
Neurons 🧠
Individual cells in the nervous system that receive, integrate, and transmit information
Reuptake
A process in which neurotransmitters are sponged up from the synaptic cleft by the pre synaptic membrane
Epigenetics
The study of heritable changes in gene expression that don’t involve modifications to the DNA sequence
Hypothalamus 🧠
A structure found near the base of the forebrain that’s involved in the regulation of basic biological needs
Neurogenesis
The formation of new neurons
