Flashcards in Unit 3 Part B Vocabulary Deck (25):
0

The intricate fabric of interconnected neural cells covering the cerebral hemispheres; The body's ultimate control and info processing center

Cerebral cortex

1

Portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgments

Frontal lobes

2

Portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position

Parietal lobe

3

Portion of the cerebral cortex lying at the back of the head; includes areas that receive info from the visual fields

Occipital lobe

4

Portion of the cerebral cortex lying roughly above the ears; includes the auditory areas each receiving info primarily from the opposite ear

Temporal lobe

5

An area at the rear of the frontal lobe that controls voluntary movements

Motor cortex

6

Area at the front of the parietal lobe that registers and processes body touch and movement sensations

Somatosensory cortex

7

The brains ability to change, especially during childhood by recognizing after damage or by building new pathways based on experience

Plasticity

8

The large band of neural fibers connecting the two brain hemispheres and carrying messages between them

Corpus Callosum

9

Our awareness of ourselves and our environment

Consciousness

10

The principle that info is often simultaneously processed on separate conscious and unconscious tracks

Dual processing

11

The study of the relative power and limits of genetic and environmental influences on behavior

Behavior genetics

12

Thread like structures made of DNA molecules that contain the genes

Chromosomes

13

The biochemical units of heredity that make up the chromosomes; segments of DNA capable of synthesizing proteins

Genes

14

The complete instructions for making an organism consisting of all the genetic material in that organisms chromosomes

Genomes

15

Twins who develop from a single fertilized egg that splits into creating two genetically identical organisms

Identical twins

16

Twins who develop from separate fertilized eggs. They are genetically no closer than brothers and sisters but they share a fetal environment

Fraternal twins

17

The subfield of biology that studies the molecular structure and function of genes

Molecular genetics

18

The portion of variation among individuals that we can attribute to genes. The (blank) of a trait may vary depending on the range of populations and environments studied

Heritability

19

The study of environmental influences on gene expression that occur without a DNA change

Epigenetics

20

The study of the evolution of behavior and mind using principles of natural selection

Evolutionary psychology

21

The principle that among the range of inherited trait variations, those contributing to reproduction and survival will most likely be based on two succeeding generations

Natural selection

22

A random error in gene replication that leads to a change

Mutation

23

An evolutionary psychologist who developed the principle of natural selection

Charles Darwin

24

A complex molecule containing the genetic info that makes up the chromosomes

DNA
