15 children belonging to the control group will undergo the treatment by performing the procedure with images printed on laminated A4 sheets.

The main objective of the experimental protocol is to promote the development of cognitive skills, facilitate the acquisition of new skills and promote the adoption of functional and adaptive behaviors. The use of Applied Behavior Analysis procedures, with the help of technological tools such as a tablet or robot can facilitate the increase of new knowledge and skills.

The criterion is acquired if the subject emits 8 out of 10 independent correct responses (90%) for 3 consecutive sessions.

The objective is to test whether the technological tool used (tablet or robot) can make the proposed learning procedure more effective. The experimental group carries out the procedure by means of stimuli presented on tablets or robots.

Is an assessment tool that attends to all those skills that are fundamental to the development and enhancement of verbal communication skills and the proper use of language in social interactions. It focuses especially on the assessment of language prerequisites fundamental to the development of verbal behavior in accordance with the classification of verbal operants proposed by Skinner: mand, tact, echoic, intraverbal. It consists of a manual, a protocol and a set of materials (pictures and standardized items for assessment). The protocol is divided into:

• Tables
• Early Echoic Skills Assessment (EESA) - Assessment of barriers: behaviors that might hinder the child's learning
• Assessment of transitions: the child's ability to make the transition to teaching modes based on the natural context
• Task Analysis and Skills Monitoring: describes the individual milestones required to reach the main milestone
• Scoring grids
