Q

What is an independent variable

A

Variable that changes

26
Q

What is the dependent variable

A

The variable that gets effected; depends on the independent variable

27
Q

What is an experiment

A

A controlled test of a hypothesis in which the researcher manipulates one variable to discover its effect on the other

28
Q

What is debriefing

A

It’s conducted after the experiment to explain the purpose of the research to have participants leaving without negative feelings.

29
Q

What is the control group

A

It’s the comparison group

30
Q

What is a cross sectional study

A

A study in which subjects of different ages are compared at a given time

31
Q

What is a longitudinal study

A

A study in which subjects are followed and periodically reassessed over a period of time

32
Q

What is the central nervous system and describe it

A

It’s what controls the body and is at the center of our being. It contains the brain and spinal cord

33
Q

What is the peripheral nervous system

A

All portions of the nervous system OUTSIDE the brain and spinal cord “underneath the neck”; glands, organs, muscles, nerves, neurons, ect.

34
Q

What are spinal reflexes

A

A reflex that requires no thought

35
Q

What is a neuron

A

The basic cell that makes up the nervous system, receives and transmits electrochemical signals in the nervous system

36
Q

What are dendrites

A

“Branch-like/ Finger-like structures in the neuron that receive messages from other neurons” Branches of the neuron that receive neural impulses

37
Q

What is the axon

A

Tube- like structure (like an electrical cord) that conveys electrical impulses toward other neurons.

38
Q

What is the myelin sheath

A

Fatty insulation wrapped around the axons. this insulation increases the rate at which electrical impulses travel along the axon. Infants do NOT have thick myelin sheath.

39
Q

What are glial cells

A

Provide/delivers nutrients and oxygen to neurons, they produce myelin sheath, and clean up waste. Influence new neurons, especially in infancy.

40
Q

What is the synapse

A

“Formation between neurons.” Microscopic, fluid-filled space between the dendrite of one neuron and the synaptic knob of another. Neurons don’t actually touch- they are connected by this fluid. Synapses have communication links. Infants are NOT born with many synapses. Synapses build over time and with experience.

41
Q

What is a random sample and what are the shortcomings

A

A sample that gives every member of the population an equal chance of being selected and the shortcoming is it could having bias results

42
Q

What is plasticity?

A

The brain’s ability to change and adapt in response to experience, learning, or injury.

43
Q

What is neurogenesis

A

The process by which new neurons (nerve cells) are formed in the brain.

44
Q

What is laboratory observation

A

Behavior is observed and recorded in a controlled environment, typically a laboratory setting.

45
Q

What is naturalistic observation?

A

Researchers observe and record behavior in its natural environment without intervening or manipulating any variables

46
Q

What is sensation?

A

The detection of physical energy emitted or reflected by physical options. The process of receiving, converting, and transmitting information from the outside world

47
Q

What is perception?

A

The process by which the brain organizes and interprets sensory information. The method by which the sensations at any given moment are interpreted and organized in some meaningful way.

48
Q

What is Opponent- Process Theory of Color Perception?

A

Your retina reacts to the opposite color of White/ Black are a pair, as well as Blue/Yellow and Red/Green
iPhone at night…Sleep issues

49
Q

What is inattentional blindness?

A

Also known as perceptual blindness, is failure to notice an unexpected stimulus that is one’s eyesight when other attention demanding tasks are being performed. This typically happens when humans are overloaded with stimuli, and it is impossible to pay attention to all stimuli in one’s environment.

50
Q

What is micro saccades?

A

Constant eye movement, tiny little vibrations in the eye that you don’t consciously notice. i.e. Survival technique.

51
Q

What is sensory overload?

A

Peoples’ senses get overloaded when they have to process too much info; Shopping, Long music festivals, Long classes, Amusement parks Too much Stimulation (Visual, auditory, informational processing, ect. Can lead to Tired, Sleepy, Blocking out information, Anxious, Hungry, and Aggravated.

52
Q

What are Innate abilities?

A

Abilities that we are born with such as depth perception

53
Q

What is the retina?

A

Contains Visual Photoreceptor cells on the back of the eye that respond to light waves. The retina transfer images to the optic nerve, which sends visual messages to the brain.

54
Q

What is the iris?

A

Round muscle (the colored part of the eye) that changes the size of the pupil by opening and closing the pupil based on amount of light present in the environment.

55
Q

What is the iris?

A

Round muscle (the colored part of the eye) that changes the size of the pupil by opening and closing the pupil based on amount of light present in the environment.

56
Q

What are the rods in the eye?

A

Visual Sensory Receptors in the Retina responsible for ability to see in the dark. Rods are sensitive to dim/low light and darkness

57
Q

What are the cones in the eye?

A

Visual Sensory Receptors in the Retina responsible for color vision and fine detail. These are sensitive to color, brightness, and detail.

58
Q

What is perpetual constancy?

A

refers to the brain’s ability to perceive objects as stable and unchanging despite changes in sensory input, such as changes in lighting, angle, distance, or other environmental factors.

59
Q

What is the linear perspective?

A

a visual depth cue that helps the brain perceive three-dimensional space on a two-dimensional surface. It refers to the way parallel lines appear to converge as they recede into the distance, eventually meeting at a single point known as the “vanishing point” on the horizon.

60
Q

What is the cochlea?

A

a critical part of the inner ear responsible for hearing. It is a spiral-shaped, fluid-filled structure that converts sound waves into nerve impulses, which the brain can then interpret as sound.

61
Q

What is the gate control theory

A

gate control theory of pain explains how pain is not just a result of physical injury, but also influenced by psychological and neurological factors.
