The background of the study is the historic and cultural conception of development, which considers symbolic activities significant for preschool-age children. Our objective was to identify indicators of reflection as an essential feature of preschool development during the acquisition of symbolic actions at three levels: materialized, perceptive, and verbal. The design of the study was descriptive with qualitative and quantitative analysis applied. Included in this assessment of the development of symbolic function were 180 children of preschool age (from 5 to 6 years old) who were in the third year of formal preschool education in Bogota, Colombia. Qualitative analysis of the results pointed out specific indicators of symbolic development at each level. On the materialized level such indicators were the sequencing of actions with substituted objects, the generalization of the symbolic features of objects, and a verbal, coherent explanation of the mode of substitution. On the perceptive level the indicators were the generalization of features in graphic representations, the possibility of using an image as a strategy for voluntary memorization, and a verbal explanation of the use of an image as a substitution. On the verbal level reflective explanation of verbal substitution was established as the positive indicator. The results permit us to posit the usefulness of clear qualitative indicators for assessment of a child’s level of psychological development and readiness for school learning at the end of preschool.

Within the historical and cultural conception of development, signs and symbols are essential psychological instruments for transforming the psyche and the internal world of a child (Vygotsky, 1931/1983, 1982 /1993). Vygotsky stressed that the signs can be used, first, on the external social and material level and, second, on the

individual, internal, and ideal level (Elkonin, 2009- Quintanar & amp- Solovieva, 2009). In other words, internal symbols may appear only after corresponding internal actions in which such symbols might be used (Vygotsky, 1983 /1995). Afterword, within activity theory, the regularities of acquisition and the types of orientation used for actions with symbols were taken into account during the teaching process (Talizina, 2009).
At preschool age the presence or absence of symbolic function may be observed within play activity. Collective forms the social role-play are specifically useful for the introduction of symbols at the external, materialized level (Gonzalez-Moreno, Solovieva, & amp- Quintanar-Rojas, 2014a, 2014b- Gonzalez-Moreno & amp- Solovieva, 2014a, 2014b). Interaction between adults and children within play activity may be observed in materialized, perceptive, and verbal symbolic actions. It is possible to suppose that the formation of symbolic actions follows the typical sequence of stages for the formation of mental actions proposed by Galperin (1966, 1998).
Materialized actions refer to the fact that the child starts to use material objects in a particular way: an object is used in external action as a substitute for another object, which is absent (or just not used by the child). The child may express orally the meaning of such a substitution. For example, a child using a pencil as a comb for a dollcan express that he/she is combing the doll’s hair using the pencil. The child learns to reproduce the models of actions with concrete objects, and by symbolic representation such models pass to a more generalized level.
Such types of actions may be called symbolic actions, which increase significantly within play activity. The child starts to use objects not only according to the external or functional meaning but also according to the new «denomination» (Petrovski, 1985). Such a change in the use of objects also means that the child has developed the internal, constant functional image of the corresponding object and may apply this image in new, «symbolic» situations.
In this process the operations with the object correspond to the proprieties of the «absent» object, which is represented within the current symbolic action. The whole process is accompanied by the gradual development of consciousness of actions and of the meaning of objects in different actions. Plays with rules and social role-play occupy an important place in psychological development. It is possible to suppose that the absence of these kinds of play activities or the lack of possibilities for being included in such activities has a negative influence on the acquisition of symbolic function at preschool age.
Later on, symbolic actions pass to the perceptive level, on which it is possible to accomplish substitution or representation of the object graphically. «Perceptive actions require … the perceptual recognition of the elements and the comprehension of the images [that] are the symbols which may serve for the child and other people … to represent objects and events, real or imaginary» (Salsa & amp- Vivaldi, 2012, p. 135).
The level of verbal symbolic actions is the most complex at preschool age and includes the generalization of linguistic elements. A typical feature of this level is that a word has meaning and object reference (Luria, 1976). The word may be converted into a sign because it may represent not only the concrete object but also

the imaginative, symbolic object (an event, situation, feature, or action), which is not directly included in the meaning. In other words, each word has a polysemic structure that is not accessible to infants but can appear as a new, qualitative possibility at the end of preschool age. «Within the process of ontogenetic development the meaning of the words-signs is changing and its functions as well. Such changes proceed from simple denomination to complex media of abstraction» (Vygotsky, 1934 /1991b, p. 443). The meaning of the words acts as the unity within verbal symbolic actions.
During preschool age, gradual symbolic development on the materialized, perceptive, and verbal levels appears together with self-reflection. Such reflection indicates a more stable symbolic level and the possibility of flexibly using symbolic means. We can suppose that such flexibility of reflection may be related to the phenomenon of the interiorization of symbolic means (Vygotsky, 1982/1991a). «When external operation converts into internal operation, interiorization or the passage from external to internal level can take place» (Vygotsky, 1983/1995, p. 165). The presence of an indicator of reflection at three levels (materialized, perceptive, and verbal) shows the complex, gradual development of symbolic function, a process in which it is necessary to denominate particular ways of acting with objects as substitutes for other objects (images or words).
All these essential qualitative changes can take place at preschool age. «Symbolic function is essential for cultural activity and creates important conditions [for the] development of semiotic concentration of the means» required for posterior apprehension at school (Solovieva & amp- Quintanar, 2012, p. 27). It is almost impossible to imagine learning concepts at school (Talizina, 2009) without the consolidation of symbolic function at preschool age.
At the same time, not all children show the same level of flexibility or reflection for using symbolic means. In our previous studies, poor acquisition of symbolic function at all levels was detected in groups of preschool children in Mexico and Colombia (Barreto, Bonilla, & amp- Solovieva, 2013- Bonilla, Solovieva, & amp- Jimenez, 2012- Gonzalez-Moreno, Solovieva, & amp- Quintanar-Rojas, 2011- Solovieva & amp- Quintanar, 2013). At this age, qualitative indicators of the acquisition of symbolic function are important for psychological and pedagogical knowledge and assessment. For this reason, a goal of the present study is the identification of indicators of reflexive symbolic development in materialized, perceptive, and verbal actions at school age.
Design of the study
The design of this study was descriptive. Our research was based on a qualitative conception of development and assessment and was concentrated on identification and analysis of typical parameters of psychological phenomena. The program MS Excel was used for the collection of data, and statistical analysis was provided by R Development Core Team (2014).

The participants in the study were 180 preschool Colombian children from 8 educational institutions in Bogota. The age of the children was between 5 and 6 years, and all of them were in the third year of regular preschool. Four institutions were private, and the other four were public. Two types of institutions were selected because we were pretending to study general typical features of psychological development in educational preschool institutions at different levels. The institutions were located in different zones of the city and were selected on the basis of their agreement to take part in the research. Inside each institution the participants were selected by chance. Table 1 show that all participants were distributed homogeneously according to gender and kind of institution.

Instrument of assessment
In order to assess materialized, perceptive, and verbal levels of the development of symbolic function, the protocol for qualitative evaluation was used. This instrument allows the evaluation of the performance of diverse kinds of actions of substitution in collaboration with the child (Solovieva & amp- Quintanar, 2014). In other words, the instrument helps to evaluate the zone of proximate development, which in our case implies the possibility of the child’s performing symbolic actions with the external help of an adult (Vygotsky, 1982 /1991b). External help for orientation implies the elaboration of the base of action. Such orientation allows the construction of the image of the present situation, the identification of the meaning of the whole situation (its necessity or sense for the subject) and its essential basic components, the elaboration of a plan for future actions, and the regulation of the execution of the action (Galperin, 1966, 1992). Table 2 presents the structure and the content of the scheme for evaluation of actions on the materialized, perceptive, and verbal levels (Solovieva & amp- Quintanar, 2014).
To begin, all private and public preschool institutions were contacted and informed about the aim of the research. The directors of the institutions and the parents were asked to agree to take part in the study.
The scheme of the assessment of symbolic function was applied to each child individually in one session of 1 hour duration. Afterward, the analysis of the obtained results was carried out in order to characterize the responses of the 180 children.
Each child was assessed by a student in the department of pedagogy or a student at the Ph.D. level in educational sciences (one of the authors of the article). Assessors registered all performances and oral expressions of the children. Additionally, three experts were present during the procedure with each child: two psychologists and one language pathologist. The goal of this procedure was to obtain objective opinions about the absence or presence of symbolic function at different levels in each child. We then established the degree of coincidence in the opinions of the experts. All experts were previously informed about the types and levels of actions used in the assessment. After observation, each expert, individually, established the presence or absence of symbolic substitution at each level. Video recordings were used in order to provide evidence of the whole procedure. The experts analyzed the obtained data to establish the statistical coincidence of their evaluations. The collection of the data was done by using MS Excel, and statistical analysis was provided by R Development Core Team (2014).
Based on the children’s performance during assessment, types of positive and negative responses were established (Table 3).

After identification of the diverse types of all the answers of the children, the results were classified according to the levels of symbolic development. This classification permitted us to establish indicators for the positive development of symbolic actions at the materialized, perceptive, and verbal levels (Table 4). During evaluation each expert assigned 0 or 1 to each observation (0 = no symbolic action observed- 1 = symbolic action observed) using formal protocols for each of the 180 participants.

In order to establish the degree of coincidence of the evaluations of the children’s answers by the three experts, Kendall’s coefficient of concordance (W) was used (Kendall & amp- Babington, 1939). The level of significance chosen for our analysis was 1%. In this case, if the p value of W is bigger then 0. 01, the result is considered to be product of causality and is not significant statistically. However, if the p value of W is less than 0. 01, the result is the product of intrinsic coincidence according to the experts and is statistically significant. It was determined that the three experts gave coincident evaluations of the responses of children at the level of 1% of significance (Table 5). In the table only positive responses are taken into account and not all types of responses of all the participants.

tions indicators of reflexive development are the sequence of actions of substitution, the generalization of the symbolic features of an object, and an explanation of how the process of substitution was managed. For perceptive symbolic actions such indicators are the generalization of the symbolic features of the represented word (or situation) in the image, the use of the image as a means (strategy) for positive memorization, the recognition of the produced image by the child and by an adult, e the child’s reflexive explanation according to the content of the task. On the level of verbal actions only one indicator can be distinguished- that indicator is the coherent explanation of and the production of an adequate story following the verbal instructions of an adult.
In our opinion, one of interesting findings of our study was the identification of indicators that might provide precise information for a psychologist about a child’s level of functioning or initial acquisition of symbolic function. The results show that verbal regulation was present as an indicator of reflexive execution at the level of materialized actions. At the same time, an essential difference among the levels was that on the materialized and perceptive levels verbal regulation would not by itself be enough for efficient realization of the action of substitution. We can see that for only 4 children within the studied population was the verbal symbolic level accessible (Table 5). Such data permit us to suppose that the achievement of a high level of symbolic function (verbal level) at preschool age is possible only in connection with the previous positive development of symbolic external materialized and perceptive actions. Gradual use of these external means in plays and artistic activities is essential for positive qualitative psychological development (Vygotsky, 1926/2001). In our previous studies the levels of symbolic function were determined in assessed populations of Mexican and Colombian preschool children (Bonilla et al., 2012- Gonzalez-Moreno et al., 2011). At the same time, it is possible to confirm that specific orientation with the help of external signs and symbols proposed by an adult through group social role-play can guarantee positive changes in symbolic development in children between 5 and 6 years old (Garcia, Solovieva, & amp- Quintanar, 2013- Solovieva & amp- Quintanar, 2012).
The complex level of symbolic development, the level of verbal actions of substitutions, can be characterized as the level on which words start to operate not only as a means of communication and regulation but also as a means of mental internal representation of phenomena and situations. Vygotsky (1931/1983) explained that «verbal actions modify the process of thinking and convert it into a verbal, conceptualized, and mediated process. At the same time, these actions permit [one] to precisely organize and orientate the perception, which converts to a selective, objective, and exact process. «
As we mentioned, the presence of indicators of reflexive development at the level of verbal actions reflects the possibility of representation at a high level. One of the main difficulties pointed out in our study is the low level of symbolic development in the studied population, which confirms our previous findings. For example, only 15. 56% of assessed children succeeded in realizing the sequence of actions of substitutions in reflexive materialized symbolic actions- only 9. 44% showed some kind of ability in generalizing symbolic features on the perceptive level, and only 2. 22% showed reflexive verbal development of symbolic actions. Thus, regular children with no evident developmental problems do not show a sufficient degree

of symbolic development at the end of preschool. The difficulties of reaching this benchmark increase from the materialized level to the verbal level. This situation indicates the necessity of reconsidering the strategies for pedagogical and psychological educational work in both private and public institutions (Gonzalez-Moreno & amp- Solovieva, 2014b). The common traditional strategy preschool educators use first of all is repetitive reproductive tasks such as repetition of vocalizations, numbers, and letters. Such tasks have nothing to do with the necessity of developing symbolic function in materialized, perceptive, and verbal actions. We are convinced that the best strategy for changing the present situation is by remembering and emphasizing preschool activities that involve social role-play (Elkonin, 1980- Solovieva & amp- Quintanar, 2012) and all kinds of narrative-play (Bredikyte, 2011).
