This paper examines learning and dialogue with pattern languages, using psychological theories outlined by Lev Semenovich
Vygotsky. Vygotsky, known as the Mozart of Psychology, is a Soviet psychologist who examined developmental psychology fromboth experimental and theoretical perspectives. This paper focuses on the function of pattern languages using Vygotskian
theories such as Vygotsky’s triangle (subject – sign - object), zone of proximal development, inner speech, and predication.
Through this examination, the following ideas are proposed. Patterns in a pattern language support human action much likethe “signs” in Vygotsky’s triangle. The act of choosing and executing a desired pattern can be understood as development oflearning that result from setting one’s own zone of proximal development. Furthermore, patterns are written with predication(when written in Japanese), making the patterns feel as though it is the inner speech of the reader, which encourages readers
to incorporate the patterns into their learning. The paper focuses on examining theories of Vygotsky, but aims to provide
understanding on the function and meaning of pattern languages.

1. INTRODUCTION
During the first half of the twentieth century in Soviet, there was psychologist named Lev Vygotsky,
who through his immense contribution was later called “the Mozart of Psychology.” Through his
research in developmental psychology, he made many significant contributions including his theory on
cultural and biosocial development, known as cultural-historical psychology. His theory that humanreasoning is mediated by signs and symbols is another contribution that remains influential.
In this paper, the function of pattern languages is examined through such Vygotskian perspective.
The reader may wonder whether there is validity in examining a theory that was created more thaneighty years ago, in a societal context that is very different from the present world. However, thisquestion can be countered by the simple fact that Vygotsky’s theoretical framework remains
influential in the study of learning and development, and that his works continue to be referenced byresearchers in this field.
2. THE FUNCTION OF PATTERN LANGUAGES AS VYGOTSKIAN SIGNS
Vygotsky went beyond the stimulus-response paradigm and proposed that psychic tools mediatefunction. Because psychic tools form as a result of loose societal connections, the workings of the mind
are not closed to individuals but are rather mediated socially. This indicates that education can affectindividuals’ learning and psychological development. Vygotsky’s view of the mediatory relationshipbetween the workings of the mind and societal intermediaries is an idea that remains true in modern
psychology.
The description above is represented by what is called “Vygotsky’s Triangle” (Figure 1). This figure
shows us that we as “subjects” relate to “objects” through “signs”, which mediate our actions (Vygotsky,1987). We do not directly influence the world with our own hands, but do so through artificial tools, or“signs”1 These signs are not creates by individuals but are rather formed by the society as a whole.
Using this framework, we can say that pattern languages function as “signs” (psychic tool) thatmediate the relationship between the subject and the object (Figure 2). First of all, pattern language
function as signs, which help recognize the world by using them. This is consistent with ourunderstanding of pattern languages as glasses of recognition (Figure 3). Moreover, pattern language

There is another outstanding philosopher who studied relation between language and thought: Charles Sanders
Peirce, the father of Pragmatism and semiotics. Only few papers consider the relation between Vygotsky andPeirce (Edwards, 2007; Miller, 2011). Although, in our view, Peirce's philosophy is quite important to position
pattern language in philosophy, this paper focuses only on Vygotsky's theory because of avoiding complicated.

also function to enhance a person’s motivation to try the action that is suggested as the solution ineach pattern. Therefore, patterns have the ability to encourage a person’s future action.

Figure 3: Pattern Language as Glasses of Recognition
In The History of the Development of Mental Functions (Vygotsky, 1997), Vygotsky uses the“Buridan’s ass” paradox to describe the function of “signs.” This paradox is named after the fourteenth
century French Philosopher and scientist, Jean Buridan. Although Buridan was not the one to comeup with the paradox, it continues to be called by this name.
The anecdote is as follows. A hungry ass is placed equally between two very similar stacks of hay.
In this situation, the ass is bound to die of hunger because the inducement placed on the ass is equallystrong and pulling in opposite directions. In other words, the ass dies of hunger due to its inability tomake a rational decision. Through this example, he shows his criticism toward a mere stimulusresponse way of thinking, and also rejects a priori-based philosophical thinking.
What Vygotsky instead proposed is the idea that humans deal with these sorts of paradoxes bybringing in “signs” that are unrelated to the given situation. Flipping a coin to make a decision isan example. The flip of the coin in this case function as a“sign” that helps the decision-making
process.

According to Vygotsky’s way of thinking, the flip of the coin introduces a completely new framework
than the Buridan example. By flipping the coin, the person is setting an action-stimulating factor, andis using it to control his or her own course of action. Therefore, people are able to get aid from
artificial stimuli when making their own decisions.
Vygotsky also refers to William James’ analysis on voluntary act using the example of a person
waking up in the morning. The example says that when a person awakes from sleep, they experience
conflicting emotions of knowing that they must wake up and also wanting to sleep longer. Therefore,
there is a conflict of motives that appear in the mind simultaneously. When under such a situation, aperson may decide to count “one, two, three” and wake up at the count of three. In this instance theperson is setting a stimulus (the counting), and acts in response to it, thereby successfully controlling
his or her own actions.
According to Vygotsky, the creation and usage of stimuli to encourage one’s own action is a way to
distinguish higher-level actions from basic actions. He observed that the usage of both artificial
stimuli and stimuli given in a particular situation is the distinct characteristic of human psychology.
Such artificial stimuli are what Vygotsky called “signs.” The signs are automatic stimuli thathumans bring into their minds and use as auxiliary motives. According to his definition, signs are thevarious stimuli that a person induces with the intent to control the course of action for himself orothers.
Signs function similarly to “tools”, but these two things are not the same. Vygotsky makes thedistinction in the following statements: “the tool’s function is to serve as the conductor of human
influence on the object of activity… it must lead to changes in the object. The sign, on the other hand,changes nothing in the object of a psychological operation. It is a means of internal activity aimed at
mastering oneself” (Vygotsky, 1978, p.55). Simply put, the tool is externally oriented whereas the sign
is internally oriented.
According to Vygotsky, the most exemplary form of “sign” that exist is words. Words mediatehumans’ higher mental functions and enables people to control their mentality and act upon it.
Pattern languages also function as mediators of words and are “signs” that encourage people to takeaction based on mental inputs.
3. THE ZONE OF PROXIMAL DEVELOPMENT
Perhaps the most well known Vygotskian theory is the “zone of proximal development” (ZPD)(Vygotsky, 2012). Vygotsky’s definition of the zone of proximal development is as follows: “the distance
between the actual developmental level as determined by independent problem solving and the levelof potential development as determined through problem solving under adult guidance, or incollaboration with more capable peers.” (Vygotsky, 1978, p.86). This theory is closely related to hisargument that a child’s state of development should not only be measured in terms of the knowledge
he or she currently has, but also in terms of his or her potential level of development. In this context,
we propose that pattern languages can support people’s growth in their zones of proximal
development. We will take a look at the zone of proximal development theory and examine its relation
to pattern languages.
As a developmental psychologist, Vygotsky argued that more attention should be given to what
learners can almost do; that is, what learners can’t do on their own, but can with guidance or help
from their peers (Figure 4). He uses an example of apples in an orchard to explain that the state ofdevelopment is not only determined by the parts that are already developed, but also by the parts thatare in the process of developing. If you owned an apple orchard and wanted to see how your orchard isdoing, you would not just count apples that are fully ripe, but would also take into account the apples
that are on its way. In the same way, one must consider not only the fully developed functions but also
the functions that are in the developing process, or the zone of proximal development of the learner.
Zone of proximal development is important because it allows us to properly redefine the concept ofdevelopment. Vygotsky stated that in ancient psychology and common knowledge, there is a strong
tendency to see “imitation” as something that can be done simply and functionally; something thatanyone can do.

Figure 4: Zone of Proximal Development
However, children can only imitate actions that are within the range of their present abilities.
Therefore, in order to imitate an action, there must be some sort of transition from what the learner
cannot do to what they can do. Thus, children can always do more if they have guidance. However,this does not mean that they will be able to do everything; it must be within the range of potential
ability for the child. Therefore, Vygotsky concluded that the possibility of learning is dependent on thechild’s zone of proximal development, and insisted that teaching is only effective when the teacher isable to anticipate the child’s potential development (Vygotsky, 2012).
Vygotsky’s theory of the zone of proximal development has been applied to pedagogy in schools. The
ideas of the theory have been used in designing education with a focus on the students’ zone ofproximal development, and guiding their development. The theory has also been influential in thediscussion of what the roles of teachers are in an educational setting.
With this background, this paper will examine the function of pattern language as a way to support
growth in one’s zone of proximal development. Pattern language aims to enable the learners to choose
and practice the patterns on their own, without having to get help from others (teachers).
Consequently, pattern languages have the potential to expand one’s zone of proximal development
internally.
According to Vygotsky, the zone of proximal development differs from person to person (Vygotsky,2012). Children that are the same age will be at different development stages due to that fact that
their zones of proximal development are unique and differ from their peers. Therefore, it's reasonable
that when you share a pattern language with a group of people, each person has a difference
combination of patterns that they have or have not experienced, or would like to experience in the
future. Furthermore, it is crucial for a person to choose their own desired patterns based on theirpresent situations in order to maintaining a continuous cycle of learning 2.
Here we show some cases to better understand and visualize the concept of the zone of development,
through examples of applying the Learning Patterns. The Learning Patterns consist of 40 patterns toenhance creative learning by providing an opportunity for learners to reflect on their learning styles,
to discover or rediscover good habits, and to obtain new insights into how they can become a better
learner (Iba, et al., 2009; Iba & Miyake, 2010; Iba & Sakamoto, 2011; Iba & Iba Lab, 2014a). We haveorganized dialogue workshops where participants used the Learning Patterns to reflect on theirexperiences, talk about them with others, and make plans for future actions using the patterns (Iba,2015).
In this workshop, participants are first asked to look at the Learning Patterns and recall theirexperiences with the patterns. Secondly, they are asked to choose five new patterns that they wish tomaster in the near future. Then, participants are free to mingle and talk with other participants.
When they find another participant who has already experienced a pattern they want to master, theylisten to the other participant’s story (Figure 5).

2 Another type of dialogue to apply patterns into daily life is“Pattern Concierge.” See Mori et al. (2016).

Figure 6 is a chart presenting the experiences of freshmen in our university with the Learning
Patterns (Iba 2014). The green area shows the patterns he/she has experienced, and the yellow areashows which patterns he/she wants to gain. The yellow area therefore represents potential zone ofdevelopment, which was chosen by the learner. Figure 7 shows examples of other students. Theseshow the diverse shapes of experiences and various ranges of each student’s potential zone ofdevelopment. It can be considered that by using the pattern language, students are setting their own
zone of proximal development.

After the students practice the Learning Patterns, how will these charts change? Figure 8 showsthe evolved chart of the same student shown in Figure 6. The dark green area shows the range ofexperience when the student was a freshman, and lighter area shows the expanded zone of experience
after 1.5 years.

Figure 9 shows pattern-experience charts of students in the Iba lab, arranged by the number ofyears that have passed after the first experience check when they were freshmen. Although each is
unique, you can see the trend that the green zone (experienced) expands year by year. Figure 10
shows the expansion of two different student’s experiences from when they were freshman, three
years later, and then five years later.

The examples so far show growth of learning experiences, but we can grasp the shape ofexperiences using other pattern languages as well. Figure 11 shows a student’s growth of experience
with the Collaboration Patterns (Iba and Isaku, 2013; Iba & Iba Lab, 2014b). At the beginning of eachsemester, each student in the Iba Lab writes a plan for their learning and collaboration in projects,
using the Learning Patterns and the Collaboration Patterns. The yellow area represents the zone ofpatterns that he/she said would like to experience in the coming semester, and the orange area
represents the experienced he/she has already experienced. It can be considered that through thisprocess, the students are designing their own learning in their zone of proximal development;
something that is possible because they can refer to the patterns. Other examples are shown in Figure
12 3.

3 It is possible to make a comprehensive chart that shows learning and evolution within a group of people (or evensociety). We currently do not have enough data to get a good insight on the evolution, but we believe this ispossible, and could be something to work on in the future.

4. INNER SPEECH AND THE PREDICATE
In Thought and Language (Vygotsky, 2012), Vygotsky examines the relationship between thought
and language, and discusses the characteristic of “inner speech.” Inner speech is speech that isformulated within the mind but not expressed out loud as spoken language. Inner speech may include
thoughts like, “(I) should go eat lunch after work is over” or “What should (I) do tomorrow?”
Vygotsky states that one characteristic of inner speech is that it is completely in the form ofpredicate. In other words, human thoughts exclude the use of pronouns, and are instead centered on
the predicate. Therefore, inner speech is not going to be something like “After I finish my work, I am
going to get myself some lunch.” The sentence’s subject is naturally omitted in a person’s mind,
because there is no need to specify the subject when talking to oneself through inner speech.
This characteristic is important when considering pattern languages, because when a person reads
a pattern and thinks about the action they will take in the near future, the pattern will be replayed in
the mind as inner speech. Thus, when thinking about how to put a pattern into action, the reader will
form an inner speech in which the pronoun is omitted.
On the other hand, sentences that are written out will have syntax. This is because the written
language does not have am interlocutor, and thus the sentences must provide detail about who or
what the subject is. In written language, the interlocutors are in various situations, so there is not acommon subject that can be used. This is why the written language must be written more specificallyand structurally complicated than spoken language.
Interestingly, sentences in the Japanese language can exist without the specification of pronouns at
all times, even when written. This is because Japanese is a pro-drop language that allows sentences tolack an explicit pronoun, without even changing the verb form4. Therefore, when writing pattern inJapanese, we are able to completely omit the pronoun, just as we do when we form inner speech in our
minds. The original Japanese version of the patterns we have been writing are all written without the
specification of the pronoun.
Figure 13 shows the Japanese version of “Self-Intro Album” (No.13) of Words for a Journey patterns(Iba et al, 2015a, 2015b, 2015c, 2016). There are 15 sentences in Japanese: 1 sentence in Introduction,
1 in Context, 4 in Problem, 5 in Solution, 4 in Consequence. All of these sentences were intentionally
written without indicating the pronoun, or the subject of the sentences to the reader. That is, the word,“you” is never mentioned in the pattern. On the contrary, in the English version (Figure 14), there are
13 sentences in the pattern, but the word “you” appears as the subject 6 times, and 3 of the sentences
are imperative. Although the pro-drop characteristic is inevitably lost when the patterns aretranslated into English, the Japanese version of the patterns is completely pronoun-less in all sections(context, problem, solution, consequence) (Figure 15).
By avoiding using the pronoun of the subject, “you,” pattern descriptions can be written in innerspeech style. When the word, “you” is used in a pattern description, it implies that there is someone
within the sentences who is giving advice to the reader. On the contrary, in the Japanese description
without the “you,” the reader doesn't have to suppose that there is somebody who is giving advice. We
do this with to intent to make the patterns read as if it is the inner speech of the readers themselves,
instead of advices from the pattern writer. So when writing the patterns in Japanese, the solution is
written without a pronoun, making it easier for readers to feel as if the words came from their own
inner speech.

4 Note that the Japanese language drops pronouns even though the verbs do not change forms based on pronouns.

Korean language is the same to Japanese. Spanish and Italian are other pro-drop languages, but omitted
pronoun can be imagined by knowing he changes in verb form. Russian are similar to this type of language.

Figure 15: Comparison between Japanese sentence and English sentencein the “Self-Intro Album” pattern
In addition, it can also be noted that the Solution statement of the patterns in Japanese is not
written as imperative sentences, but as normal sentences without a pronoun (Figure 15). The
Japanese language does not differentiate its present tense and future tense verbs. Therefore, thereader can choose the tense of the sentence as they see fit in their situation. For instance, if they havebeen already doing the Solution, they can read the sentence in the present tense; if they have neverdone the pattern, they will read the solution in the future tense. Thus the readers can understand thesolution sentence of the pattern as either a statement of what that person is currently doing (present
tense), or something the person will do in the future (future tense).
In addition, Vygotsky also discusses the case of pure predication in external speech (Vygotsky,2012). When communicating by external speech, there is no need to specify the subject pronoun if thelistener is aware of the conversation’s context. The dialogue workshops we have held in the past years
where participants discuss about their life experiences using the patterns, is an example of this(Figure 16). During the one-on-one conversations that take place, the person who is speaking will omit
the subject pronoun once the context has been shared and mutually understood with the listener.
Once the subject can be omitted, the conversation will be reduced to predicates, since there is nolonger a need to specify the subject pronoun of the conversation. Therefore, the speaker will only talkabout the experiences themselves, and the listener will assume that the subject is the speaker.

5. CONCLUSION
In this paper, we explore the function of pattern language with Vygotsky’s psychology, especially,signs as psychic tools, Zone of Proximal Development, and inner-speech and predication. In thisconsideration, the differences among languages are studied. We anticipate that this paper evoke
future discussion on the function of pattern language with psychology.
