The Need for Science
The tendency to believe, after learning an outcome, that one would have foreseen it.
Hindsight Bias
In an experiment, the group exposed to the treatment
Experimental Group
The difference between the highest and lowest scores in a distribution
Range
The sense or act of hearing
Audition
Research that compares people of different ages at the same point in time.
Cross-Sectional Study
A testable prediction.
Hypothesis
Assigning participants to experimental and control groups by chance
Random Assignment
A computed measure of how much scores vary around the mean.
Standard Deviation
The most common form of hearing loss, caused be damage to the cochlea's receptor cells or the auditory nerve.
Sensorineural Hearing Loss
Agents, such as chemicals or viruses, that can reach the embryo or fetus during prenatal development and cause harm.
Teratogens
Repeating the essence of a research study, usually with different participants in different situations, to see whether the basic finding can be reproduced.
Replication
A research procedure in which both the research participants and the research staff are ignorant about whether the research participants have receive the treatment or placebo.
Double-Blind Procedure
The strength of the relationship between two variables.
Effect Size
Our sense of smell.
Olfaction
An optimal period early in the life of an organism when exposure to certain stimuli or experiences produces normal development
Critical Period
All those in a group being studied, from which random samples may be drawn.
Population
In an experiment, a factor other than the factor being studied that might influence a study's results.
Confounding Variable
Numerical data used to measure and describe characteristics of groups; include measures of central tendency and measures of variation.
Descriptive Statistics
The number of complete wavelengths that pass a point in a given time-for example, per second.
Frequency
A concept or framework that organizes and interprets information
Schema
The tendency for extreme or unusual scores or events to fall back toward the average.
Regression toward the mean
