Q

what did Wundt state were the goals of his lab

A

to discover the facets of consciousness, its combinations and relations, so that it may ultimately discover the laws which govern these relations and combinations –> consciousness = sum of facts of which we are conscious

Q

what did Wundt state were the two factors of conscious experience

A
  • content of the experience (objects/events that are present for the observer)
  • what the observer makes of that content (“apprehension”) –> how the individual interprets the context, processes (this was his primary focus)

Q

how did Wundt describe the differences in the research approaches of the natural sciences and the research approach of psychology

A
  • natural sciences concern themselves with objects of experience (independent of the subject) –> “mediate experience”
  • psychology investigates the whole content of experience in relation to the subject and in regard to the attributes which this content derives –> “immediate experience”

Q

describe what psychology tries to do, as argued by Wundt

A
  • psychologists are studying the experience of an experiencing person
  • real meaning of the studies comes from an understanding of how objects in the external world are part of the individual’s experience
  • conscious experience exists in the experiencing person

–> e.g. if tree falls in the woods does it make a sound –> it does make sound waves (physically) but does not make a sound psychologically

Q

what is apperception

A
  • an active intentional process involving will –> parts of consciousness would have a greater focus/clarity
  • important for bringing some part of conscious experience to maximal clarity
  • principal process by which psychical elements and compounds were synthesized into new conscious experiences –> “creative synthesis”

Q

how did Wundt’s experiments show evidence of apperception

A
  • observers were expecting some stimulus occurrence (listening or looking for it)
  • when stimulus occurred, they would focus attention on it and largely ignore the rest of the stimulus array

27
Q

what did psychological experiments mean for Wundt

A

experiments had to be done to determine causality, and psychological processes were emphasized as mental processes

28
Q

how did Wundt study consciousness

A

introspection –> “experimental self-observation”

29
Q

describe how Introspection was carried out by Wundt

A
  • observers (typically his doctoral or post-doc students) were trained
  • observer presented with some stimulus condition and were instructed to be in a state of readiness and was told when the stimulus would be presented
  • observers were supposed to give an account of what they experienced
  • trials repeated with stimulus value changing
30
Q

describe how Wundt’s experiments resembled those of today

A
  • training an observer (familiarization)
  • presentation and manipulation of IV
  • measurement (DV)
31
Q

describe the main psychophysical method that Wundt used

A
  • reaction time method –> was used by Helmholtz in measuring speed of nerve conduction
  • influenced by Donders who studied reaction time of mental events –> “mental chronometry”
32
Q

describe mental chronometry

A

method made by Donders to study reaction time of mental events –> reasoned that if thinking involved neural transmission then one could measure the speed of certain mental problems by measuring reaction time and subtracting our the time required by the sensory (afferent) and motor (efferent) components –> Wundt used this method in his lab

33
Q

describe the process of a simple reaction time task vs choice reaction time task

A
  • having subject press a key as soon as saw stimulus
  • after multiple trials, experimenter could average the values for an average reaction time
  • could then compare simple reaction time to choice reaction time (press one button if see blue, other button if see red)
  • difference would be speed of the mental event (choosing which button to press) –> this procedure was eventually deemed invalid, but reaction time is still used today
34
Q

what were scientific apparatuses used by psychologists for

A

since they were studying the immediate experience, the devices were used for systematic and controlled presentation of stimuli to humans, and recording responses to the stimuli

35
Q

what was most of Wundt’s lab work dedicated to

A
  • half was on processes of sensation and perception
  • most vision –> depth perception, color vision, negative aftereffects, visual illusions, colour blindness
  • some on audition (tone perception), touch (two-point thresholds) and time perception
36
Q

describe Wundt’s tridimensional theory of feeling

A
  • placed all emotions on three continua: pleasant-unpleasant, tension-relaxation, excitement-depression
  • shifted focus to this later on in his work
37
Q

describe Wundt’s Völkerpsychologie

A
  • translated nowadays as social psychology, folk psychology, and cultural/ethnic psychology
  • study of the relationships among religion, art, language, custom, morality, myth and culture
  • higher human mental processes, according to Wundt
  • argued these could not be studied with experimental methods –> understood through cultural anthropology, sociology and social psyc
38
Q

why has Wundt’s Völkerpsychologie been largely ignored/not translated by historians

A

they didn’t know about it, or doesn’t fit with the story of a history of scientific psychology

39
Q

why was Wundt’s Völkerpsychologie important

A

precursor for contemporary fields like linguistics, cultural psychology, social psychology and personality –> essential compliment to experimental psychology

40
Q

who was the first American psychology student to visit Wundt’s lab

A
  • Hall –> earned doctoral degree in psychology with William James beforehand –> returned to establish first psychology lab in America at Johns Hopkins university
  • Cattell and Wolfe were first to get doctoral degree from Wundst
    –> three most important American psychologists of their time
41
Q

who did Ebbinghaus work with

A

he worked by himself

42
Q

how did Ebbinghaus get the idea to start studying memory

A

he read Fechner’s book “elements of psychophysics” –> reasoning it might be possible to use procedures similar to psychophysical methods described by Fechner to investigate higher mental processes like learning (association) and memory

43
Q

why did Wundt (and others before Ebbinghaus) argue it was not possible to investigate higher mental processes

A

language, learning and memory were interfere with this study –> this would bias self-observations

44
Q

how did Ebbinghaus conduct his studies

A
  • he did them on himself –> tested memory under a variety of conditions
  • decided not to test himself with words because they had meaning (which could lead to associations) –> made nonesense syllable (e.g. XAJ) and would draw them in random samples for his study
45
Q

describe earlier investigations of associations (pre-Ebbinghaus), and what did Ebbinghaus want to add to this research

A
  • carried out by empiricist philosophers
  • typically generate a list of words, present them one at a time to the subject and then ask them to generate as many associations as possible
  • this research was on associations that were already formed, but Ebbinghaus wanted to research associations as they were being formed
46
Q

how did Ebbinghaus eliminate confounds in the experiments he did on himself

A
  • he tried to keep his life conditions reasonably constant (tested himself same time each day, maintained constancy in testing environment, tried not to vary his activities in hour before tests)
  • used metronome to keep timing constant when reciting syllables
  • tried to keep same voice inflection
47
Q

what are some of Ebbinghaus’s important findings

A
  • the forgetting curve (most forgetting occurs in first few hours after learning and then levels off at a slower rate)
  • length of series affects number of trials. needed for learning –> this relationship is not linear
  • re-learning affects memory retention
  • number of repetitions affects forgetting
  • learning meaningful material vs non-meaningful material and how forgetting differs in these cases
48
Q

what additional contributions to psychology did Ebbinghaus make (other than memory)

A

developing testing procedure that influenced the development of intelligence testing

49
Q

what was Brentano’s version of psychology called

A

act psychology

50
Q

what is act psychology (Brentano)

A

a molar psychology that called for a larger unit of analysis in looking at consciousness –> argued it was important to study the act of seeing itself and not to focus on what was seen –> postulated intentionality in conscious acts

51
Q

describe the role of intentionality in Brentano’s act psychology

A

individuals intended to do, see and experience things, thus there was a purpose to consciousness –> thought psychology should study the actions of consciousness rather than the contents of consciousness (which foreshadowed functional and Gestalt psychology)

52
Q

how did Brentano think science should be conducted

A

with experimentum crucis (crucial experiment) –> science was best served by a few grad experiments that tested big questions, with a few smaller studies to round out the edges

53
Q

how did Brentano differ from Wundt

A
  • believed only a few grand studies should be conducted (whereas Wundt thought science was best served through a systematic series of small studies)
  • Brentano opposed the use of introspection (thought it was impossible for observers to report with accuracy)
54
Q

what did Stumpf do in his early career

A
  • did work on perception, specifically depth perception –> cognitive psychology
  • tone perception
55
Q

describe some of Stumpf’s work on sensation and perception

A
  • overtones (harmonics)
  • combination tones
  • beats (inter-tones)
  • pitch perception

–> all work in audition

56
Q

describe Stumpf’s work in psychology of music

A
  • started massive project involving years of study on psychology of tones
  • tonal fusion (hearing a single tone when two different tones played together) –> argued this was due to degree of consonance of tones (e.g. Perfect 5ths)
  • psychological nature of melodies
57
Q

what field of work did Stumpf pioneer

A

comparative musicology or “ethnomusicology”

58
Q

who were some of Stumpf’s students

A
  • Köhler & Koffka (found Gestalt psychology)
  • Lewin (part of Gestalt group and helped develop experimental social psyc)
  • Pfungst (him and Stumpf investigated the case of Clever Hans, the horse that could “count”) –> found out that the horse’s trainer was giving him subtle cues
59
Q

describe Müller’s principle work

A

he mostly did work with memory –> replicated Ebbinghaus’s work and extended it

60
Q

how did Müller extend Ebbinghaus’ work

A
  • asked subjects what they were thinking in the various replicated memory tasks –> what strategies they were using the memorize the lists
  • learned there were many cognitive strategies (assigning meaning to stimuli, chunking, etc.)
  • tried to look at why forgetting occurred –> interference theory, proactive/retroactive inhibition, generalization of information from one task to another
61
Q

describe the memory drum that Müller invented

A
  • systemized the presentation of stimuli for memory tasks
  • staple in psychology labs around the world for decades
62
Q

describe the success of Müller’s lab in comparison to Wundt’s

A
  • it gained European students but not as many American ones
  • few of his papers were translated to English
63
Q

who did Külpe earn his doctorate with

A

Wundt –> took first course with him, then went to study with Müller, then returnd to Leipzig

64
Q

what was the focus of Külpe’s research

A
  • higher mental processes, especially thinking (not allowed to do this in Wundt’s lab)
  • developed introspection procedure that involved retrospection (which Wundt did not approve of either)
65
Q

describe Külpe’s method of introspection

A

“systematic experimental introspection” –> observers would experience whatever stimuli or events they were supposed to, then provide comprehensive accounts of the mental processes involved –> reports taken at end of event, thus “retrospective”, but got around the problem of memory by dividing tasks into meaningful components (with introspective components in each) –> “fractionation”

66
Q

what was Külpe’s findings about thought processes

A

when observers were given instructions, introspective accounts indicated that the instructions were incorporated before the task –> when the number pair occurred, the subject didn’t have to think “I must add these numbers”, they just did it –> this was called “mental set”

67
Q

What was Külpe’s more controversial finding

A
  • Wundt & Titchener believes all thought was composed of sensations or images, but Külpe heard introspection that suggested the opposite
  • e.g. did not indicate sensory/imaginal content present when making judgements about the weight of an object
  • “imageless thought”
