- Nature of information transmission in the nervous system: both chemical & electrical
- The nervous system is a system of neurons.
(A neuron consists of three parts: body, dendrites, axon.)
- Neurons send electrochemical signals through their axons to other neurons to produce thoughts, feelings and actions.
- However, there is a narrow gap between every neuron called the synapse, which cannot be crossed by the signals produced
by these neurons. → when neurotransmitters are used
- Neurotransmitters: chemical messengers stored in the axon and released into the synaptic gap
- When the electrical impulse reaches the end of the axon, a neurotransmitter is released into the synaptic gap → allows transmission of signals from one neuron to the next.
- There are various different types of neurotransmitters in the brain and each of them have their own effect on the human body.
E.g - oxytocin: aka "love hormone" -
plays a role in trust, empathy, social bonding, reproduction, and childbirth.
Are used to get a sense of an individuals strengths and weaknesses, particularly when mental retardation or brain damage is
expected
-also used to identify gifted children and children with intellectual difficulties

General and specific components
Common Intelligence tests (task and behavior)
-WAIS (Weschler Adult Intelligence Scale)
... verbal abilities, visuospatial abilities, working memory and processing speed
-WISC (Weschler Intelligence Scale for Children)
-Woodstock-Johnson Test of cognitive abilities
Verbal Abilities
-working memory and processing speed
-overall intelligence
-visual vs verbal
-strength/weaknesses
Tests were designed to measure basic intellectual abilities like abstract reasoning, verbal fluency, and spatial memory
-IQ: used to describe a method of comparing an
individual's score on an intelligence test with the performance of individuals in the same group, mean=100
-IQ= measure of current cognitive function
Disadvantages: little consensus to what is meant by intelligence, success in life is strongly influenced by social skills and other talents not measured, biased in favor of middle-and-upper-class educated individuals because they are more familiar with these kinds of reasoning
