Sociocognitive performance in autism spectrum disorders and interference of the therapeutic environment

Purpose: To analyze the sociocognitive performance of children and adolescents with autism spectrum disorders in two environments of language therapy, which differ as to the physical structure. Methods: Ten children and adolescents with ages between 4 and 13 years, of both genders, diagnosed with autism spectrum disorders took part in the study. For data collection, eight filming sessions were performed during individual language therapy lasting 30 minutes, being four in a room with conventional environmental organization (common room) and four in a room with specific ambiance [children’s interaction core (CIC) room], interspersed during a month. For the analysis of filmed situations, the Sociocognitive Performance Protocol was used and obtained data were subjected to statistical analysis. Results: No statistical significance was found in sociocognitive performance of 10 subjects in the common and CIC rooms, although specific differences were observed in some cases. Conclusion: The creation of preestablished physical environments or specific materials is not and should not be considered essential for language therapy. It is noteworthy, however, that the absence of a large volume of statistically significant data does not indicate that the results are not expressive, reiterating the need for further research in the area.

In the development process of children, there is a small relation between the cognitive, affective, social, and communicative areas, which are the foundations for symbol emergency (2) .The social and affective deficits in the ASD are associated with cognitive damage that leads to a poor development in the game, therefore the child does not have appropriate emotional and cultural cycles for a typical development (3) .For the speech therapy practice, knowledge on the existent variations in the relations between the areas is extremely important in the intervention process, because it shows that peculiarities of the delays in language development may be analyzed under different perspectives (2) .
Another aspect that should be considered in speech therapy interventions is related to the variables concerning the environmental context of language therapy (7)(8)(9)(10) .Several researchers, based on a pragmatic perspective of the language, pointed out the importance of the context for communication (7,8) .
The context in which communication occurs is complex and includes multidimensional aspects; therefore, its analysis is very important to investigate characteristics associated with communication (11) such as the sociocognitive performance.For subjects with ASD, development can be favored in environments that are comprehensive and make its evolution easier and can be adjusted to its limitations (10) , and they can possibly be significantly modified from one context to another (12) .
Furthermore, literature mentions the importance that environmental context has on aspects such as behavior, attention, and expressive language in subjects with ASD (13)(14)(15) .Thus, scientific investigations are required on the language and cognitive aspects in the subjects with ASD, which take into consideration the different context elements that may interfere in the development of children with ASD (7,8) .Thus, the objective of this study was to analyze the sociocognitive performance of children and adolescents with ASD in two language therapy environments, which differ as to the physical structure.
The hypothesis that led us to carry out this study was the result of theoretical referential associated with clinical exercise showing that children with ASD might present a better communication performance in an environment that is structured, functional, and familiar to the child than in a conventional room of speech therapy.

This research was approved by the research ethics committee of Faculdade de Filosofia e Ciências of Universidade
Estadual Paulista "Júlio de Mesquita Filho" (UNESP), Marília Campus, under protocol number 968/2003.All people in charge for the participants signed the free informed consent according to resolution 196/96 of the Brazilian National Health Counsel (NHC).

Subjects
Ten children and adolescents aged 4-13 years (mean = 7.9 years) were included in this research, six male and four female.All of them were diagnosed with ASD, and diagnoses were performed by a psychiatry following specific criteria (16,17) .Subjects were going through a speech therapeutic process during a period from 1 to 6 years, and the following criteria were not considered as exclusion characteristics: age, sex, education, use of verbal or nonverbal communication, and IQ.
Chart 1 presents data concerning age, sex, and speech therapy period of each subject.
Data were collected at the end of the school year of the fourth-year therapists; thus, children were receiving treatment with the same therapist for a period of around 9 months.

Procedures
Data were collected inside the Health and Education Study Center (CEES) of Faculdade de Filosofia e Ciências of UNESP, Marília Campus.This is a cross-sectional study, in which filming sessions happened in two rooms called common room and children's interaction core (CIC) room, with different physical structures.The common room presented a conventional environmental organization generally used in speech therapy, measuring 9 m 2 including table, chairs, cabinet, small mattress, and toys that were available inside a cabinet for each subject to use.However, the CIC room measured around 30 m 2 and had furniture adapted for small children and for its respective environment, such as kitchen (sink, stove, microwave stove, fridge, and table), living room (armchair and table), bedroom (wardrobe, dressing table, bed, cradle, and dolls), and other toys with the aim of representing a copy of the house.In both rooms, there were also miniatures of domestic appliances, means of transportation, animals, telephone, plastic fruits, stroller and supermarket trolley, iron, doll clothes, doll, ball, beauty salon toys (comb, brush, hair dryer, mirror, and make-up), magazines, paper, and pencil.
In the common room, toys were available inside the cabinet so that the child could use them.In the beginning of every session, the therapist opened the cabinet and the child chose the toys he/she would like to get.The child was free to request or open the cabinet to catch other toys throughout the speech therapy session.
In the CIC room, toys were exposed according to their functionality and they were at children's disposal.In both situations, therapists were requested to establish a free game situation, providing interaction, according to the interests shown by the child.
All subjects had been previously cared in two routine sessions, in both rooms.Thus, they were acquainted with these ambiances.
For data collection, filming equipment to record the speech therapy sessions was used.
Eight filming sessions of individual language therapy were recorded for each subject with ASD, during a 1-month period, and four of them were carried out in the common room and four in the CIC room, interposed.Initially, the filming session were done in the CIC room with all participants, following the order: CIC room/common room for data collection.Thus, 80 filming sessions were performed: 40 ones lasting 30 minutes in each room, totalizing 2,400 minutes or 40 hours of observation.
To analyze sociocognitive performance of children with ASD during the filmed situations, the Sociocognitive Performance Protocol (18) was used.In the analysis using such protocol, collected data were registered with numbers according to the best performance of each child in every area analyzed in the protocol: 1. gestural communicative intention, 2. vocal communicative intention, 3. use of mediator object, 4. gestural imitation, 5. vocal imitation, 6. combinatory game, and 7. symbolic game.
Each area presents a minimum and a maximum score for classification according to child's performance.The gestural communicative intention, vocal communicative intention, combinatory game, and symbolic game areas presented scores that varied from one to six, that is, the higher the grade is, the better is the performance in that area.In the gestural imitation, vocal imitation, and use of mediator object areas, the scores ranged from one to four, in which the highest classification corresponds to the best performance.All data were analyzed and transcribed and, later, the interobserver concordance index verification was carried out.The two judges were speech therapists graduated and experienced in infantile psychiatry and equivalent experience in using the analysis instrument.Therefore, eight filming situations were sorted so that each judge could analyze them, four in the CIC room and four in the common room.To calculate the concordance between judges and the first author researcher of this study about the sociocognitive aspects, the following mathematical formula was used: (100-|n 1 -n 2 |/n maximum)x100.The concordance between judges and the researcher was of 99.97%.
For the analysis of results, the best performance of each subject in every studied room was considered.From these data, the statistical analysis was carried out using Student's t-test to compare results concerning the sociocognitive performance in every room.The 5% significance level (p<0.05) was used to apply the statistical test.

RESULTS
Table 1 presents the score of the best performances in the gestural communicative intention (GCI), vocal communicative intention (VCI), use of the mediator object (UMO), gestural imitation (GI), vocal imitation (VI), combinatory game (CG), and symbolic game (SG) during the eight sessions, in the common and CIC rooms, respectively.
Table 2 shows the scores summary of the sociocognitive performance of the subjects with ASD in the common and CIC rooms through means and standard deviation of scores obtained from the Sociocognitive Performance Protocol.Besides, it also presents results related to the comparative analysis of the sociocognitive performance of 10 subjects in the common and CIC rooms.
It was also seen, after applying the Student's t-test for paired data, that there was no significant difference in the sociocognitive performance of 10 subjects in the common and CIC rooms (Table 2).Furthermore, it should be mentioned that no significant differences were seen concerning therapy duration and age of the participants' variables.

DISCUSSION
Although results have showed that the difference seen in the sociocognitive performance of the subjects with ASD, when both rooms were compared with different kinds of physical organization of the environment, was not statistically significant, it should be pointed out that only the best sociocognitive performances of each participant were considered.These findings are in agreement with those seen by other authors who also mentioned that the subjects with ASD may present similar sociocognitive performance in the different communicative situations studied (2) .
In the gestural communicative intention area, most individuals presented similar performance in both rooms; therefore, this aspect did not present a variation due to the environment context.A study (18) spontaneously and directly performed also could not find a difference in this area, probably because the child would not need to make use of gestures to get the toy, because there were several toys at his/her disposal.
In addition, it was seen that 70% of the subjects had similar performance in the vocal communicative intention in the common and CIC rooms, therefore the context did not interfere in this aspect.However, a study (18) states that when the child has verbal language, he/she will probably use it in any moment during the 30 minutes of the filming session, indicating that such aspect may happen regardless of the environment context.
No mediator object was used in 30% of the subjects, and the worst performance was seen in 40% of the subjects in the common and CIC rooms, being the best one in 20% in the CIC room.Only 4% of the subjects presented better performance in the common room.These data confirm the findings of a study (19) that emphasized the worst performance of this aspect in spontaneous communicative situations.
As to the combinatory game, most subjects (70%) presented similar performance in the two studied rooms.These data can be compared to the findings of a study (18) showing that the spontaneous situation favors the appearance of a combinatory game.
Of the 10 studied subjects, 60% presented similar performance in the symbolic game in both rooms, and the others (40%) had better performance in the CIC room.A study (18) indicates that the subjects with ASD showed better performance for the symbolic game in the test situation than in the spontaneous one.In this study, the CIC room seems to favor the appearance of the symbolic game because materials were exposed according to their functionality and were at children's reach.
It should be mentioned that a higher number of subjects presented better performance in the CIC room compared to the vocal imitation (60% of the subjects).Half of them (50% of the subjects) for the gestural imitation area, only 20% of the subjects achieved better performance in the common room and 30% presented similar performance in the two rooms, as shown in Table 1.These data confirm the statement (20) that physical contexts such as tables and chairs tend to provide less possibilities of gesture expression than large environments such as the CIC room.
According to other authors (10,21) , different contexts in situations of individual speech therapy for the subjects with ASD imply differences of performance, but such changes are also related to time and interference of several speakers and not only to the context.Regardless of the physical environment and of the adopted therapeutic proposal, the speech therapist will be in charge of process distinction acting like an ideal speaker and a mediator of the therapeutic process (7) .
When analyzing individual tendencies, there were some characteristics that are in agreement with those of the other authors (2,3,5) who saw heterogeneity in the sociocognitive performance of the subjects with ASD.It is important to explore individual differences because they are associated with diagnosis and prognosis of language and interaction of the children with ASD, besides they help creating strategies of interventions more directed to the needs of each case (22) .
Sociocognitive performance can be used as a support instrument in the therapeutic process, making the identification of variables that may interfere in the communicative performance easier (2) .Thus, the study on sociocognitive aspects of the subjects with ASD can offer subsidies to prepare and use new techniques and procedures that favor the communicative process efficiently (2,3) .
Data presented herein suggest the need of new researches such as longitudinal studies about the interference of the physical context, to better clarify the possible interferences related to the sociocognitive performance of the subjects with ASD in different ambiances of language therapy.

CONCLUSION
Analysis of the relations between sociocognitive performance of children and adolescents with ASD and physical structure in language therapy situations allowed verifying that the difference seen in the room with conventional structure applied in speech therapy clinics and in that with specific environment was not statistically significant.Thus, the creation of preestablished physical environments or specific materials is not and should not be considered essential for language therapy.It is noteworthy, however, that the absence of a large volume of statistically significant data does not indicate that the results are not expressive, reiterating the need for further research in the area.
