Q

What are the five steps in a scientific investigation?

A
  1. Formulate a testable hypothesis: to create a hypothesis, you must have a theory
    - each variable must have an operational definition
    -example: how would you operationally define someones weight? Temperature? height?
  2. Select the research method and design the study: researcher must identify the method to use base on the nature of the question under study
    - researcher would recruit participants and/or subjects to observe in a systematic way
    - participants=people
    - subjects=animals
  3. Collect the data: researchers use a variety of data collection techniques
    - example= questionnaires
  4. Analyze the data and draw conclusions: researchers use statistics to access the results of the data and determine whether their hypothesis can be supported
  5. Report the findings: researchers prepare a report that is delivered at a scientific meeting or submitted to a journal for publication
    - jornal
    - peer review proccess

Q

what are the advantages of the scientific approach?

A
  • clarity and precision (specify exactly what needs to be examined in the hypothesis)
  • intolerance of error( scientists are trained to be skeptical; findings are inspected critically for accuracy)

Q

What are research methods?

A

different approaches to the observation, measurement, manipulation, and control of variables in empirical studies
- two basic types of research methods: experimental method and correlation/descriptive methods

35
Q

what are experimental methods?

A

researchers manipulates a variable under carefully controlled conditions(independent variable) to observe its effect on another variable (dependent variable)

36
Q

what is an experimental group?

A

participants or subjects receive special treatment

37
Q

what is a control group?

A

participants or subjects receive no treatment

38
Q

what are the advantages of the experimental method?

A
  • conclude a cause and effect relationship
  • determine whether a particular IV (the cause) is the reason for influencing the DV (the effect)
39
Q

What are the disadvantages of the experimental method?

A
  • often artificial: it may not be realistic or practical in the real world
  • not all variables can be manipulated because it would be unethical
40
Q

What are the correlation/descriptive methods?

A
  • the methods do not provide a cause and effect relationship, but they still provide a relationship
  • the goal is to see whether there is a link or association between the variables of interest without the researcher having full control of how these variables are manipulated
41
Q

what is correlation?

A

determine if two variables are related to each other based on two factors: direction and strength through a numerical value called correlation coefficient

42
Q

what is a correlation coefficient?

A

a statistical number indicating whether the relationship between two variables is strong or weak

43
Q

What are the descriptive methods?

A

naturalistic observation: the researcher carefully observes behavior without intervening directly with the subjects
case studies: an in depth investigation of an individual or special group
surveys: questionnaires or interviews to gather data on attitudes, beliefs, and behaviors

44
Q

what are the advantages of the descriptive method?

A
  • able to explore uncontrolled behaviors
  • less artificial in a non-laboratory setting
45
Q

what are the disadvantages of the descriptive method?

A
  • unable to determine a cause and effect relationship
  • you don’t know if x causes y or if y causes x; therefore your unable to know which is the independent and dependent variables
46
Q

what are other concerns in evaluating research?

A

scientists are fallible human beings and their studies are not always free of errors

47
Q

what are the ethical principles in research?

A

when researchers have people participating in their study, there are important guidelines to follow:
- participation is voluntary(participates can withdraw at any time)
- there should be no harmful or dangerous treatments given to participants
- if deception was involved in the study, participants should be debriefed(informed of the true nature and purpose of the research) as soon as possible
- peoples privacy should never be compromised: data should remain anonymous and confidential

48
Q

what is positive correlation?

A

both variables go in different directions (represented as a positive(+) sign)
- x goes up and y goes down. or x goes down and y goes down

49
Q

what is a negative correlation?

A

both variables go in different directions (represented as a negative(-) sign)
- x goes up and y goes down or x goes down and y goes up

50
Q

what are neurons?

A

individual cells in the nervous system that receive, integrate, and transmit Information

51
Q

what is the soma (cell body)?

A

contains the cell nucleus and most of the chemical machinery common to most cells

52
Q

what is a dendrite?

A

part of a neuron that receives informations

53
Q

what is the axon?

A

a long thin fiber that transmits signals to other neurons to other neurons, muscles, or glands

54
Q

what is the myelin sheath?

A

insulating material that encases some axons

55
Q

what are the terminal buttons?

A

small knobs that secrete chemicals called neurotransmitters

56
Q

what is the synapse?

A

a junction where information is transmitted from one neuron to another

57
Q

What is a glia?

A

cells found throughout the nervous system that provide various types of support for neurons (examples: supply nourishment to neurons, remove waste products, provide insulation around many axons)

58
Q

what is the resting potential?

A

electrochemical reaction between ions: electrically charged atoms ad molecules (going inside and out of a neuron)
- stable, negative charge when cell is inactive or at rest(-70mv)

59
Q

what is the action potential?

A

a very brief shift in a neurons electrical charge that travel along a axon
- channels of a membrane open
- positive charged ions rush in (magnetism)
- less negative and more positive then fires (only for an instant)
- voltage then races down axon
- absolute refractory period: minimum length of time after an action potential, another cannot begin(1-2 ms)

60
Q

what is the all or none law?

A
  • a neuron either fires or it doesn’t
  • all action potentials are the same size
  • neurons convey the strength of a stimuli through the rate at which it fires action potentials
61
Q

what are the five steps of synaptic transmission?

A
  1. synthesis of neurotransmitters and storage in synaptic vesicles
  2. synaptic vesicles touch the membrane of the presynaptic cell and release its contents in the cleft
  3. unused neurotransmitters go through inactivation (convert) or removal (drift away)
  4. reuptake: when neurotransmitters are “sponged up” from the synaptic cleft by the presynaptic membrane
62
