Johannes Muller

He developed the law of specific nerve energies, which states that the nerves are the responsible for perception and our ability to sense our environment.

Got it
Weber-Fechner Law

This law is concerned with the differences in stimulus, such as quantity or intensity, that are only just noticeable to a person. It expounded on Ernst Heinrich Weber's theories.

Got it
Phrenology

This is the act of looking at the skull's shape and size and using what you find to make judgments about a person's personality or how (s)he will behave. It was developed by Dr. Franz Joseph Gall.

Got it
Difference Threshold

This refers to the smallest possible amount that a stimulus has to change for individuals to note that something is different at the minimum of one-half of the time.

Got it
Lobotomy

This surgery removed the brain's frontal lobe. This was used to treat mental illnesses in the past, particularly by those who followed somatogenic theory.

Got it
Hysteria

In the past, this diagnosis was given to people who were physically healthy but displayed physical symptoms. Magnets were sometimes used to treat this.

Got it
Somatogenic Theory

This theory about mental illness argues that these disorders arise from ailments that are biological or physical in nature.

Got it
Absolute Threshold

The smallest amount of energy that an external stimulus needs to produce in order for one of our senses to detect it

Flashcard Content Overview

These flashcards were set up to help you review the work of:

  • Johannes Muller
  • Luigi Galvani
  • Alesandro Volta

You'll find cards that address the absolute and difference thresholds as they relate to our ability to sense an external stimulus. Phrenology, psychophysics, and mechanistic psychology are also covered by these cards. Additionally, you can focus on the Young-Helmholtz Theory and the Weber-Fechner Law.

Mechanistic Psychology

A school of psychological thought that argues that we can study people with the use of mechanical terms

Luigi Galvani

He carried out an experiment where he shocked a frog with an electric current, paving the way for modern-day electrophysiology.

Alesandro Volta

This man made the original batteries. He called his creation a Voltaic pile.

Giovani Aldini

A man who electrified corpses to move them around. He was the nephew of Luigi Galvani.

Phineas Gage

This man had an iron rod pierce his skull and go through his head. The results of his injury helped scientists see that different parts of the brain had certain responsibilities.

Psychophysics

This branch of science strives to study our sensory systems through quantitative means. It can be used to evaluate all five senses.

Two-Point Threshold

This spatial measurement refers to how far apart two touches have to be before someone can differentiate between them.

Young-Helmholtz Theory

This theory focuses on how the color receptors in the human eye pick up color and allow us to perceive it.
