00700 I never had the pleasure of meeting Frieda Fromm-Reichmann
00800 but I did have almost an opportunity which I should have seized. For
00900 a year she was at the Center For Advanced Study in the Behavioral
01000 Sciences at Stanford. But there is an unwritten rule among the locals
01100 in the Bay Area not to bother visiting scholars.I regret I did not
01200 break the rule in this case. We had published books on psychotherapy
01300 at about the same time, she as an expert and I as a neophyte. We
01400 might have been able to share stories about what comes your way when
01500 you write about something in which EVERYONE feels he is an expert.
01600 In re-reading Frieda Fromm-Reichmann's book and other
01700 publications I could not find any discussion of childhood autism and
01800 its treatment. However there is ample evidence in her writings that
01900 she was not reluctant to take on difficult problems and use
02000 imaginative methods. It is because of this spirit of innovation and
02100 willingness to undertake the hitherto discouraging, that I am honored
02200 to receive an award bearing her name.
02300 Today I would like to tell you something about a new
02400 computer-based method for stimulating language acquisition in
02500 nonspeaking austistic children.
02700
02800 No one person invented and developed the method I shall
02900 describe. Hence let me first acknowledge my indebtedness to my
03000 co-workers at Stanford University- Horace Enea, David Smith, Malcolm
03100 Newey and Maxine Colby, each of whom has put years of effort into
03200 this project.
03300
03400 We began about seven years ago with a working hypothesis and
03500 two well-known facts about childhood autism. The hypothesis was that
03600 nonspeaking child's primary difficulty lay in an inability to process
03700 symbols, language being of course the most important symbolic system
03800 used in human communication. The first well known fact indicated
03900 prognosis was highly correlated with speech, the outlook for
04000 nonspeakers being poor. The second fact was the common observation
04100 that these children played for hours with machines but remained
04200 indifferent to interactions with people.
04300 There is now increasing evidence in the research literature
04400 supporting this hypothesis of a primary difficulty in symbol
04500 processing. [Churchill,1972; Frith,1972; Hermelin and O'Connor,1970;
04600 Rutter, Bartak and Newman,1971]. A dysphasic or developmental aphasic
04700 child also has difficulty with language but he can acquire usage of
04800 other symbolic systems such as gesturing and drawing. But the
04900 nonspeaking autistic child has great difficulty with all symbolic
05000 systems, not just language.
05100 The cause of this condition remains unknown. Nowadays few
05200 experts in the field defend a strictly psychogenic etiology since the
05300 supporting evidence is weak and the disconfirming evidence is gaining
05400 in strength [Rutter et al.,1971]. Regardless of the original cause,
05500 if we believe we understand the crux of the child's difficulty, we
05600 can try to devise a remedial treatment which takes advantage of the
05700 child's fascination with machines. Our idea then was to create a
05800 machine a nonspeaking child could play with in which the play process
05900 involved the use
06000 The system we developed consists of a television-like screen
06100 and a typewriter-like keyboard in front of which the child sits or
06200 stands. There is no computer visible since it is located in another
06300 part of the building. Pressing a key on the keyboard causes a letter,
06400 word, phrase, or picture to appear on the screen accompanied by the
06500 sound of a human voice saying the linguistic expression or something
06600 else which might interest a child. It is much like having one's own
06700 Sesame Street to play with. But instead of being a passive recipient
06800 of what the television show provides, a child in our situation is an
06900 active instigating agent who controls the machine. The merits of such
07000 a machine are that it is untiring, predictable, always saying the
07100 same thing the same way, never angry, never bored and controllable-
07200 properties which are notoriously lacking in humans.
07300 This audio-visual-tactile experience is directed by a
07400 computer program running on a PDP 6/10 time-shared system at the
07500 Stanford Artificial Intelligence Project. The program is divided into
07600 games intended to provide a child a variety of opportunities at
07700 playing with and interacting with symbols. For example, in one game
07800 when the child presses the key showing the letter "H", an "H" appears
07900 on the screen and a voice says "H". In another game pressing this key
08000 produces a horse on the screen accompanied by the sound of running
08100 hooves. There exist over 1000 such experiences on the system. The
08200 games are organized at various levels of complexity and are designed
08300 to show a child how English is put together from sounds and letters
08400 into words and expressions. The idea is that in playing he will begin
08500 to copy or approximate the sounds he hears associated with what he
08600 sees on the screen. I shall not go into the details of the games here
08700 They are throughly described in the literature,[Colby and
08800 Smith,1971]. Instead I shall try to sketch the rationale or major
08900 principles underlying this approach.
09000 First, consider how normal children acquire language. They
09100 are not taught formally as are adults learning a second language.
09200 Children are simply exposed to members of a linguistic community and
09300 given an opportunity to explore language usage in everyday
09400 communication with other humans who encourage and sometimes correct
09500 them. From this exposure, exploration, and corrective feedback they
09600 come to associate the sounds and meanings of words. They come to
09700 grasp that certain that certain sounds, human voice sounds, are not
09800 just sounds in themselves like wind in the trees, but that they are
09900 about something else, that is, they are symbolic. Human voice sounds
10000 are perceptual invariants about other invariants. Between the ages
10100 of roughly 2 months and 4 years normal children spend thousands of
10200 hours listening, practicing and playing with language. Mastery of a
10300 language, that is getting most of it right, does not come until far
10400 into adolescence, if ever. A normal child can make an interpretation
10500 of expressions he has never heard before. A nonspeaking autistic
10600 child does not show this course of development.
10700
10800 The problem is not simply the development of language skills but also
10900 the acquisition of concepts necessary for a comprehensive enough
11000 model of how the world works, especially the human world. The
11100 conceptual or cognitive deficits shown by nonspeaking autistic
11200 children involve those concepts which are normally acquired through
11300 language or other symbolizations. Take the abstract concept of
11400 `danger'. To prevent a child from becoming hurt, a parent must
11500 identify certain concrete objects and situations as dangerous until
11600 the child grasps the abstract concept of danger. All this is done
11700 linguistically and through pointing. By way of language, objects and
11800 situations can be referred to and warned about even when they are not
11900 present, and referred to without pointing when they are present. An
12000 important socialization function of language is to mark off for a
12100 child what to pay attention to and what is to be done and not done.
12200 Many of the characteristics of autistic children, for example, the
12300 lack of empathy, can be viewed as a consequence of an inability to
12400 form regular conceptual patterns about the world because the
12500 necessary concepts acquired through language are absent or poorly
12600 developed. As one perceptive mother said about her autistic child, `a
12700 screw is not loose, a screw is missing'.
12800
12900 A poorly developed ability to process symbols has further
13000 consequences besides conceptual deficits. Without language a human
13100 has no awareness of being aware. He lacks the ability to
13200 self-monitor and to self-control by talking to himself. He cannot
13300 use symbols reflexively, that is, to give himself orders and to
13400 comment on himself to himself. Having language, a normal child comes
13500 to realize the self is really two which can talk to one another.
13600 Finally to become a person, one must be recognized as a person by
13700 other people who treat you as if you had self-awareness and
13800 self-control. This recognition is virtually impossible for a child
13900 without language skills and probably represents the greatest tragedy
14000 in his life.
14100
14200 Thus far I have spoken of autistic children as if the
14300 nosological label stood for a single homogeneous group. Thirty years
14400 ago it seemed that night be the case. Now it appears as if there
14500 exist several autistic syndromes, none of which should be confused
14600 with childhood schizophrenia since they differ in onset, course,
14700 symptoms, family history and prognosis. There are speaking and
14800 nonspeaking autistic children. Among the nonspeaking group there are
14900 those whose linguistic development is normal until some time in the
15000 second year when they lose their language abilities. The other major
15100 group are those children who, from the start, have trouble with
15200 language, understanding little and saying even less, perhaps one
15300 'mama' or `no' a year. In our experience the most difficult
15400 problem for differential diagnosis lies in deciding whether a
15500 nonspeaking child suffers from dysphasia {developmental aphasia},
15600 autism or perhaps both. Over time the correct diagnosis can be made
15700 when it becomes clear that the dysphasic child can mimic, draw
15800 pictures and signify greetings while the autistic child cannot.
15900
16000 Taking a cue from the normal child who treats language as a
16100 toy, our first principle was that the treatment should provide an
16200 opportunity for exploratory play. The treatment situation is not one
16300 of forced drill, instruction or training but one of play with the
16400 keyboard and video display. Operant conditioning methods reward the
16500 child with candy or food for his actions. We do not, believing that
16600 food rewards inhibit exploratory curiosity, as has been shown in
16700 animals both by Harlow and by Nissen. From our own experience and
16800 that of workers in computer-aided instruction, food rewards are
16900 distracting and disrupting. Exploratory learning requires a situation
17000 which invites exploration, and provides time, security and minimal
17100 interference by adults.
17200
17300 In each of the sessions the child has a `sitter', an adult
17400 whose main task is to sit and not interfere. The sitter's task is
17500 difficult, especially if he has been trained to DO things. We want
17600 to give the child an opportunity to freely self-select those symbols
17700 which interest him, rather than to have an adult instruct him or quiz
17800 him about those symbols which he `should' learn. The sitter's
17900 behavior is crucial to this treatment method if the spirit of play
18000 rather than drill is to be provided. Of course the sitter offers
18100 social approval and encouragement when it is fitting.
18200
18300 An ideal treatment session results when the child is in a good mood,
18400 is interested in working the keyboard display, enjoys imitating the
18500 sounds and is successful in getting the machine to do what he wants.
18600 The principle of success is important here because, in our view, many
18700 nonspeakers have given up on language. They have failed over and
18800 over and hence withdraw from trying. We do not let them fail. As
18900 one normal child said about the experience "It's fun, you can't
19000 lose". There are students of autism who consider nonspeaking
19100 autistic children to be innately withdrawn from people and hence not
19200 acquiring language. We feel it is the other way around; they have so
19300 much difficulty with language they withdraw from people who
19400 unwittingly flood and overwhelm them with meaningless noises. No
19500 wonder they do not call, address, ask or answer questions of these
19600 giants who immediately spout gibberish. Autistic children are not
19700 aloof and indifferent to all people -- only to those who talk. I
19800 have often wondered if it is not eye-to-eye contact they avoid but
19900 eye-to-a-mouth which, as far as the child is concerned, simply
20000 jabbers. If you say little or nothing to a nonspeaking child on
20100 first meeting him, you will more than likely find him in your lap, as
20200 affectionate as any other child.
20300 As with any treatment method, we have had successes and
20400 failures. Every treatment of autism has reported its dramatic
20500 successes with one or two children. What is needed are long case
20600 series before we can sensibly compare methods and decide which is
20700 more effective relative to the effort and cost required. Thus far our
20800 series of nonspeaking autistic children totals 17 with 13 of the
20900 children improved. By improvement we mean that the child begins
21000 voluntarily to use speech for social communication. We do not claim
21100 the method results in normal language ability with full comprehension
21200 and correct articulation and grammar. Our aim is to kindle a child's
21300 interest in using speech, to get him to try again and again, to
21400 catalyze his damaged or slow-developing natural process of language
21500 acquisition.
21600 Our non-random sample of 17 is too small to arrive at firm
21700 conclusions about the method. However our improvement rate at this
21800 point in time represents the best reported in the literature. Some
21900 cautions are in order. Language improvement represents only a first
22000 step. These children still need a lot of help and have a long way to
22100 go to reach whatever is their potential.
22200
22300 Why haven't other workers tried this zero-risk and
22400 potentially promising method? Aside from the inertia which all new
22500 methods must face, there are two reasons. One is that everyone has
22600 his own preferred method which he believes in and may wish to
22700 improve. The other involves people's beliefs and misconceptions
22800 about computers. I have come across people with the following fantasy
22900 about our situation -- that we have a small, cowering, bewildered
23000 child sitting in front of a towering bank of flashing lights {the New
23100 Yorker-cartoon concept of a computer} while cold scientists in white
23200 coats observe him thru one-way mirrors. They say "the child is
23300 already too interested in machines, he needs relations with people --
23400 you are making him into even more of a robot". I hope from my brief
23500 description you can see this is a misconception of our situation.It
23600 may sound paradoxical, but some nonspeaking children can become more
23700 human, i.e. become language users, by way of a machine which talks
23800 and which they find more acceptable on their own terms than they do
23900 talking humans.
24000
24100 A more realistic objection to computers is their cost. Few
24200 people in the world have access to million dollar computers for this
24300 sort of work. But a large computer is not necessary to carry out
24400 this method. Mini-computers costing only a few thousand dollars are
24500 adequate. It may be that we do not need a computer at all if someone
24600 found a way to rapidly random-access both sounds and pictures. We
24700 are investigating this possibility. Once we can get the unnecessarily
24800 Satanic image of the computer out of the picture , I hope others will
24900 join us in discovering more about this technique for treating
25000 nonspeaking autistic children.
