Q

Research Methods

Correlation vs Causation

A

Correlation between two factors does not automatically conclude causation. There may be a reason one variable is positively or negativey affecting another, but that doesn’t mean one caused the other.

A proper experiment needs to be run to determine true causation and, in come cases, may be time consuming, expensive, and unethical.

25
# Perception Clarified Accommodation of the Lens
Lens change shape to focus on different distances
25
# Perception Clarified Retinal Disperity | "Stereopsis"
The left and right fields of vision provide slightly different visual images when focusing on a single object
26
# Perception What are the innate aspects of perception?
- Gestalt psychology - Gibson’s “visual cliff” - Fantz studies of infants
27
# Perception (Gestalt) What is the Figure / Ground Principle?
The figure-ground principle states that people instinctively perceive objects as either being in the foreground or the background. They either stand out prominently in the front (the figure) or recede into the back (the ground). | Face / Vase optical illusion
28
# Perception (Gestalt) What are Gestalt's Laws of Grouping?
- Proximity - Similarity - Closure - Continuity - Connectedness
29
# Perception (Gestalt) Define proximity?
Describes how the human eye perceives elements that are close together as more related than elements that are further apart Ex: thephotographisunderapot the photograph is under a pot
30
# Perception (Gestalt) Define similarity?
When things appear to be similar to each other, we group them together Ex: In a color blindness test, we group the colored dots distinct from the background that make a letter to test color perception
31
# Perception (Gestalt) Define closure?
People will fill in blanks to perceive a complete object whenever an external stimulus partially matches that object Ex: Drawn triangle with unclosed tips is perceived as closed
32
# Perception (Gestalt) Define continuity?
We are more likely to see continuous and smooth flowing lines rather than broken or jagged ones Ex: Connect the dots puzzle, even before completed, appears to make an image
33
# Perception (Gestalt) Define connectedness?
Elements that are connected to each other by color, lines, frames, or other means are perceived as more related and grouped than elements with no connection Ex: Pairs of dots connected by a line version dots with no connections
34
# Perception (Gibson) What is Gibson's Visual Cliff?
A visual cliff involves an apparent, but not actual, drop from one surface to another. It was originally created to test babies' depth perception, and is formed by by connecting a transparent glass surface to an opaque patterned surface. | Baby unexposed to the visual cliff didnt fall cause of innate perception
35
# Perception (Fantz) Define innate perception of facial design?
Fantz found that babies preferred to look at a human face (something that they see everywhere all the time) for a longer period of time than any other pattern They liked to look at more complex stimuli than simple ones
36
# Sensory Processing What is Top-Down Processing?
Top-down processing is guided by higher-level mental processes, as when we construct perceptions, drawing on our experience and expectations
37
# Sensory Processing What is Bottom-Up Processing?
Analysis of a stimulus that begins with the sense receptors and works up to the level of the brain and mind is referred to as bottom-up processing
38
# Sensory Processing What is the sensory process chain of events?
Stimuli -> Sensory Receptors -> Nerve Pathways -> Brain | The arrows represent transduction
39
# Sensory Processing What is the Absolute Threshold?
Our awareness of faint stimuli illustrate our Absolute Threshold – the minimum stimulation needed to detect a particular stimulus 50% of the time.
40
# Sensory Processing What is the Subliminal Threshold?
The level at which the participant is not aware of the stimulus being presented
41
# Sensory Processing What is Difference Threshold?
The Difference Threshold is the minimum difference between two stimuli required for detection 50 percent of the time
42
# Sensory Processing What is Weber's Law?
Ernest Weber noted that two stimuli must differ by a constant minimum percentage (rather than a constant amount), to be perceived as different. Weber fraction: k = I/I.
43
# Sensory Processing What is Sensory Adaptation?
The diminished sensitivity to an unchanging stimulus | Getting used to an odorous smell
44
# Sensory Processing (Eyes) How does information travel through the eye?
Light enters the CORNEA, passes through the PUPIL (surrounded by the IRIS), travels into the LENS behind the pupil, and creates an image in the RETINA which contains PHOTORECEPTORS. After traveling through the retina, information travels through the BIPOLAR CELLS, GANGLION CELLS, AXONS (which make up the optic nerve), and, finally, to the BRAIN
45
# Sensory Processing What is Habituation?
results from reduced (mental) attention to constant stimuli. | Not feeling your butt after sitting for extended periods of time
46
# Sensory Processing (Eye) What is a Blind Spot?
Point where the optic nerve leaves the eye because there are no receptor cells located there
47
# Sensory Processing (Eye) What is Fovea?
The fovea is responsible for sharp central vision, which is necessary in humans for reading, watching television or movies, driving, and any activity where visual detail is of primary importance. ## Footnote Cones cluster in and around the fovea, the retina’s area of central focus.
48
# Sensory Processing (Eye) What does constant eye quivering enable us to do?
- Focus the light on our retina. - Adjust the size of the pupil - Minimize sensory adaptation.
49
# Sensory Processing (Eye) What are the functions of rods?
- retinal receptors that detect black, white, and gray (Rhodopsin) - Dim Light - None in Fovea - Low Acuity
50
# Sensory Processing (Eye) What are the functions of cones?
- retinal receptors that detect fine detail and give rise to color sensations - Bright Light - Dense in Fovea - High Acuity
51
# Sensory Processing (Audio) What are audiotory sensory receptors?
hair cells on the basilar membrane inside the cochlea of the inner ear
52
# Sensory processing (Audio) Intensity (Decibels)?
Loudness
53
# Sensory Processing (Audio) Vibration Rate (Hertz)?
Pitch
53
# Sensory Proocessing (Audio) Complexity of Sound Waves?
Timbre
54
# Sensory Processing (Audio) How does sound pass through the ear?
Sound enters the OUTER EAR, is amplified, and then chutes sounds into the canal. Sound enters the middle ear, the EARDRUM vibrates the HAMMER and ANVIL, and sends the sound through the STIRRUP and OVAL OPENING into the inner ear (COCHLEA). The tiny hairs in the cochlea are activated, and the brain interprets the signal.
55
# Personality What is the NEO-PI?
**This is the most widely used of the “objective” type of personality assessment instruments. **It was created and developed through the method of “factor analysis.” With repeated use with various populations and analysis of results there have been gradual refinements to maximize reliability and validity of the measurements.
