The participation in our studies consists in coming with your child one day for half an hour at most. We will show you a short movie, and we will observe the natural reaction of the infant, who will be accompanied by his/her parents at all times.

Throughout the years, several studies with babies from different range of age take place in our laboratory (the age of the infants depends on the question we want to answer). Specific techniques and methods are applied in each study according to the goal of the study.    


Voices Discrimination

Researcher: Alba Ayneto

Ages: 7-8 months

Duration: 5-10 minutes

In this study we want to analize if babies are able to distinguish between different unknown voices. To find out we observe their behavior while listening to them.


Roles sociales y confianza

Researcher: Jesús Bas

Ages: 18-20 months 

We study  how social roles associated to different people (dominant or subordinate role) interfere with children 's confidence when learning new information. Infants watch some videos where two girls interact with a teddy bear . Later, the two girls teach where they have to look at the screen when a particular sound  is heard and then the animal appears at the specific location .


Then we test  how infants have learned to correlate the sound with  the appearance of the image according to what each girl has taught.

Roles de liderazgo

Researcher: Jesús Bas

Ages: 12, 15 and 18 months

We are studying whether children are able to understand the social roles that exist in a relationship of leadership and which are, for them, the implications of such relationships.

We have designed a study to babies using the eye-tracker. Children first see each animated videos where there are four different agents. Two of these agents make two different movements (one jumps and the other goes from one side to the other), then the rest of agents mimic one of the first (the leader). We studied whether children realize the existence of these different roles.

Later the "task" is changed and raises the possibility that one of the agents will go with the "leader" or "non-leader". At this point we study what do children expect will happen.

CV words

Researchers: Camillia Bouchon
Ages: 4, 8 and 11 months
Duration: 4-8min
In this study we want to know if consonants, which are more important to identify words, are already more important for babies than vowels in the first words they know, such as leche, boca, coche, cuento, papá, mamá, etc... Or if they attend more to their vowels because they are more salient acoustically.
CV nonwords
Researchers: Camillia Bouchon, Irene Torres, Jean Remy Hochmann
Ages: 8 and 12 months
Duration: 5-10min
In this study we want to know if babies pay more attention to the consonants or the vowels of the new words they are learning.

Object processing

Researcher: Marc Colomer

Age: 5-6 months

Adults have the capacity to infer others' intentions and predict others' actions, which is fundamental for successful social interactions. In this study we want to investigate whether this capacity is already present at the age of 6 months old.


Asociaciones audiovisuales

Researcher: Mathilde Fort, Edina Hajnal

Age: 12-13 months

Duration: 3-4 minuts

The goal of this study is to observe if babies from their  firsts months of life associate the visual cue of a talking face to it’s auditory  consequence ( the sound of the corresponding speech)


Eyes Mouth Learning

Investigadora: Mathilde Fort, Edina Hajnal

Age: 15 meses

Duration: 5 minuts

In this study we measure if infants value differently the information coming from the mouth area from the information coming from the eye area . To do so we observe whether babies do learn better the sequences of moves that come from the eyes or on the contrary, the ones coming from the mouth.


movimiento cejas (zona ojos)

movimiento labios (zona boca) 1



Pupil Dilation

Researcher: Jean-Remy Hochmann

Ages: 4, 7 and 12 months

Duration: 10 minuts

Can young infants represent abstract concepts such as the relations "same" and "different"? In this study, we ask whether infants can learn to predict that two syllables should be the same, or that two syllables should be different. We measure the variation of their pupil's diameter to understand when they are surprised.



Researcher: Alexandra Ibáñez Lillo

Ages: 8, 15 y 19 months

Duration: 3- 4 minuts

Using categories is a very economical learning strategy because it allows us to acquire a lot of information quickly. Babies are able to make simple grouping since their first months of life. The aim of this study is to explore the relationship between language and the formation of categories. We show babies a video with pairs of objects belonging to different categories and then analyze whether they have a preference for objects that have been reinforced by language or for those who have not been named.


Logic reasoning

Researchers: Ana Martin , Cesana - Arlotti Nicolo and Luca Bonatti .

Age: 12 and 18-20 months .

Duration : 10 minutes

In this study we investigate the logic mechanisms that babies apply to evaluate some sequences and actions. We show them some videos where some objects appear while we observe where they direct their attention.


Researcher: Loreto Nácar

Age: 8 months

In this study we want to know if babies can differentiate between sign languages. To do so, we show the babies a video of a woman signing in a sign language and when they start to get bored, we change the language to see if they are surprised by the change .
