Q

What are the 3 stages of Comte’s Theory of Science?

A
  • all human societies go through 3 stages

Q

Hermann von Helmholtz (1821-1884) was a student of ________

A

Mueller
he went rogue and confronted vitalistic psychology

40
Q

von Helmoltz pushed _________ to its extreme

A

mechanistic physiology

41
Q

What is von Helmoltz’s Law of Conservation of Energy? How does it apply to frogs?

A
  • a machine is simply a device for transforming energy of one kind to another kind
  • showed that amount of heat + energy produced by frog muscles is roughly equal to the energy released from oxidation of the food it ate
  • so living things also follow law of conservation of energy!!
42
Q

Who did research on the conduction velocity of nerves in a frog leg in the 1850s?

A

Hermann von Helmoltz

43
Q

von Helmoltz measured the conduction velocity in frog legs and found that it was much (slower/faster) than previously thought. The speed was ____m/s, which is a little more than ____km/h.

Why did these results stun people?

A

SLOWER; 30 m/s, a little more than 100km/h

stunned ppl bc when we perceive things it feels instantaneous (30 m/s is slow if we think about a whale – a whole second for message to pass from tail to brain)

44
Q

What is the metaphor of mental energy?

A
  • energy was very modern term in 1850s
  • explains mental phenomena in physicalist terms
  • maybe we can transform other kinds of energy into mental energy?
  • can be conducted (channeled), accumulated and discharged
45
Q

Who is the distinction btw sensations and perceptions attributed to?

A

Hermann von Helmoltz

46
Q

How does von Helmoltz distinguish sensation and perception?

A

Sensation: raw elements of conscious experience (require no learning or prior experience) (ie blobs of colour and light)

Perception: meaningful interpretations given to sensations (ie face)

47
Q

von Helmoltz was also a ______ and investigated the working of the eye from that point of view

A

physicist!

48
Q

What did von Helmoltz conclude about the eye as an optical device?

A

it is a very poor optical device

49
Q

What did von Helmoltz discover that contributed to him deciding the eye was a poor optical device?

A

the blind spot! (defect in small part of retina where optic nerve leaves eye, contains no light-sensitive receptor cells)

50
Q

In the late 1600s, Newton demonstrated visible light is made out of _______; (shorter/longer) light waves get bent more (refraction)

A

all the colours; shorter waves get bent more

51
Q

What is colour mixing (neurophysiology of colour vision)

A
  • phenomenon whereby varying mixtures of spectral light can produce the same colour sensations as pure spectral colours
52
Q

What are primary colours (neurophysiology of colour vision)

A
  • spectral colours (red, green , blue) which are the building blocks for all the kinds of colour sensation
53
Q

What is the Young-Helmoltz trichromatic theory?

A
  • Thomas Young and Hermann von Helmoltz
  • suggests there are 3 types of receptor cells in the eyes, each responding to a different spectral hue
  • this is what makes colour vision possible!
54
Q

von Helmoltz was stunned by the lack of correspondence between ______ and _____

A

our subjective perception of the world and how our nervous system is designed to perceive the world

55
Q

Compare and contrast the perspectives of Kant, von Helmoltz and Locke in terms of how we develop perceptual abilities

A

Kant: a priori knowledge is innate (never actually said we are “born” with them but many interpret him this way)

Helmoltz: perceptual processes acquired through experience (wants to reject nativism)

Locke: a person born blind and suddenly granted sight would not immediately be able to perceive environment from sight (real examples of this happening, ppl do learn to see normally but takes some time to start making sense of environment)

56
Q

What is perceptual adaptation?

A
  • idea that when a person’s visual field is altered (eg shifting images w special glasses), the brain adapts to new perceptions automatically and unconsciously
  • but this takes a few days!!
57
Q

What is unconscious inference?

A
  • according to Helmoltz
  • idea that perceptual adaptation + other perceptual phenomena might result from a process in which there is an unconscious adoption of certain logical rules

EXAMPLE:
- size of an object varies inversely with its distance (general premise is inference based on experience)
- size of ball in my vision is gradually getting smaller
- the ball is moving away from me

58
Q

What area did Ernst Heinrich Weber (1785-1878) work in? What is he known for?

A
  • interested in tactile senses
  • known for Weber fractions (JND between 2 stimuli)
59
Q

What is a Weber fraction?

A
  • the JND btw the standard and comparison weight is always close to 1/40 (or 0.025) of the standard weight
  • there is a diff Weber fraction for each sensory dimension
60
Q

Where did Gustav Fechner sit in the monism/pluralism debate? Whose position is this similar to?

A
  • dual aspect monist
  • in style of Spinoza
61
Q

What did Fechner want to prove? What idea did the start with?

A
  • wanted to prove mental + physical were 2 sides of same thing
  • started w idea that every JND is perceptually equivalent (his Eureka moment)
62
Q

Who developed the following equation? Why is it meaningful?

Sensation = k log(physical stimulus intensity)

A
  • Fechner!
  • equation showing how every JND is perceptually equivalent
  • first mathematical equation where one side is something subjective being predicted by something physical
  • proved Kant wrong: psychology can be a proper natural science!!
  • birth of psychology according to Dr. Roy!!!
63
Q

What is mental chronometry? What made this research possible?

A
  • measuring speed at which humans can perform elementary mental tasks to then make inferences ab processes involved
  • made possible by discovery that conduction velocity of nerve cells is relatively slow
64
Q

Who is Franciscus Cornelis Donders (1818-1889)?

A
  • invented mental chronometry
  • often overlooked in history of psychology
65
Q

What was the example given of one of Donders’ mental chronometry experiments?

A
  • asked to repeat a syllable, measure time btw hearing syllable and beginning of oral production (m: 197 ms)
  • other condition: present 5 syllables, only repeat ki (m: 243 ms)
  • time needed to identify identity of stimulus is 243-197 = 46
  • asked to repeat every syllable (m: 285 ms)
  • time needed for response selection is 285 - 243 = 42 ms
66
Q

What modern area of research does Donders’ mental chronometry resemble?

A

like modern cog sci experiments, only thing missing is modern statistics

67
Q

What was Wilhelm Wundt’s first study about?

70
Q

What is Wundt’s thought meter?

A
  • pendulum with horizontal knitting needle that hits bells
  • where is the pendulum when the knitting needle hits the bell?
  • perception is 100-125ms late; we don’t see and hear the bell being hit at the same time
  • argued separate acts of consciousness are involved in registering the bell and noting the position of the pendulum
  • these “acts of consciousness” became basis for his psychology
  • this contribution to the theory of sensory perception meant there was sufficient ground to establish a whole new field of experimental psychology
71

Psychology as a natural science

72
Q

A

philosophy!!

75
Q

A
  • created a journal (philosophical studies)
  • taught six-month intro course
  • trained many students (186; that’s crazy high!)
76
Q

What were the 2 introspective techniques that Wundt defined?

A
  • internal perception: un-scientific; practiced by philosophers; what Kant and Comte criticized
  • experimental self-observation: highly controlled circumstances; stimulus presented repeatedly and Ps report experiences to stimulus
  • ex ticking of metronome, played in class as example and asked how ppl perceived beat (tik tik vs tik tok tik tok)
77
Q

What is voluntaristic psychology?

A
  • general term describing Wundt’s psychology
  • emphasized events like apperception, creative synthesis, and psychic causality
  • all associated w the will or voluntary effort!
78
Q

How did Wundt distinguish apprehension and apperception?

A

Apprehension: first step in perceiving, individual beats of metronome enter consciousness

Apperception: making sense out of our experience; requires consciousness

79
Q

Wundt argued that all of Helmoltz’s mechanistic processes stopped at the level of ________. _______ requires something more than a mechanism, it is associated with ______.

A

apprehension; apperception; effort

80
Q

Psychology was evolved to fill the gaps between ___ and __

A

Sensation and motor action

81
Q

If we were to try to relate Aristotle’s epistemology to Wundt’s Voluntaristic Psychology:

Sensation would be like _______, memory would be like ________, and organized experience would be like ______.
(apperception/apprehension/creative synthesis)

A

Sensation would be like apprehension, memory would be like apperception, and organized experience would be like creative synthesis

82
Q

what was the example of remembering letters or words used to illustrate? What do we find about how many letters vs words ppl can remember?

A
  • difference between apprehension and apperception
  • we apprehend all letters but only apperceive a subset
  • number of elements is what matters, ppl remember about same # in both conditions
83
Q

Wundt observed that silent thought is more than ______. He came to this conclusion using _______.

A

more than a low-level talking to oneself
came to conclusion using introspection

84
Q

What 3 things did Wundt use to prove that silent thought is more than just talking to yourself?

A
  • we can sometimes realize our speech isn’t expressing our thoughts properly
  • we can object to something before being able to put it into words
  • we can convey the same meaning using completely different words
85
Q

According to Wundt, what is the most basic unit of thought?

A

the “general idea”, it is grasped by apperception and translated into a sentence

86
Q

What are the 3 steps in Wundt’s model ab how thought relates to language?

A

“General idea”
Apperception (not automatic, the will captures the idea through apperception)
Sentence

**all 3 levels influence each other!

87
Q

What is creative synthesis?

A
  • Wundt
  • theory that apperceived ideas may be combined/organized in many ways, including some that have never been experienced before
  • ex spontaneous strategies people used to remember letters/words during last example
88
Q

What is psychic causality?

A
  • Wundt
  • notion that there are different rules in place for apperceptive processes that do not follow the same mechanistic causality that distinguishes perceptive processes
  • partially rejects Helmoltz’ mechanistic approach
89
Q

What are the 3 dimensions of Wundt’s tridimensional theory of feeling?

A
  • tension and relief (anticipating of next beat)
