Visiting Erasmus+ summer student from Istanbul

I had the opportunity to do my first internship with Erasmus+ as a Research Assistant at Goldsmiths University of London InfantLab in the UK. This internship was with my supervisor Dr. Caspar Addyman and also with a friendly, helpful and successful group of colleagues. My supervisor had another intern like me, Marena from Boston University (with EUSA), Maisha and Angel from Summer School (A Level Psychology students) and with three PhD students Nataşa, Zehra, Giulia (post-doc) and I had a chance to work with them in the InfantLab. All these three students need to work with babies to prove their theories and write their doctoral dissertations.

Nataşa’s studies includes Voice Matching and Sounding Shapes, Zehra’s study Music in Infancy and Giulia’s study includes EEG in infants. And my supervisor has his own study called Happy Talk. During these studies, I helped them in the process of arranging the cameras in the room to be observed, preparing the certificates given to the participants, transferring the collected data to Excel, and after the studies on the basis of the reliability of the studies I did video coding and I had the opportunity to make observations during the study. I also learned thanks to my supervisor’s training the introduction to programming called R Studio, which is similar to SPSS but done by coding. As a result of this programming, I learned how to create and interpret tables in Excel.

The InfantLab is not only a place where I do my internship, it is a working environment that helps me to exchange a lot of ideas with my colleagues and to make new friendships, to learn new information about psychology and to improve my language. After an efficient and enjoyable two-month internship, I received my Erasmus+ certificate and said goodbye to the InfantLab.

The Happy Talk Study

“Happy Talk” is the first study in the InfantLab’s new eyetracking lab. We are looking at what makes Infant Directed Speech so attractive to babies.

What is Infant Directed Speech?

No matter the language or region of the world, people always tend to talk to babies in a slow and high-pitched tone, many times with a smile on our faces. It is second nature for us to change the way that we speak and the pronunciation our words when we are talking to babies rather than when we are talking to adults. Just go ahead and try talking to your baby the way you would normally, it’s hard isn’t it? This type of heightened toned and slowed speech is referred to as infant directed speech (IDS) as opposed to regular adult directed speech (ADS).

Past Research

A past study has shown that this is a consistent change mothers make to their voice when talking to their baby, no matter the language being spoken. This shows that IDS consistent across cultures and therefore must have some significant meaning to babies. The researchers believe the change in tone is a ‘cue mothers implicitly use to support babies’ language learning’. (Source).  Past research has also shown that one month old and newborns both preferred the infant directed speech to the adult directed speech. The researchers state that this is most likely because of the exaggeration of the prosody, the stress and intonation in speech, of words (Source). This study looked at the preferences of babies under one month old, to see whether they favoured a character speaking in IDS or one speaking in ADS. The results of this study showed that newborn babies’ preference for the characteristics of IDS is present from birth, the researchers however do also consider the possibility of parents talking to their babies before birth playing a role in these results.

“Language but also emotion”

Another study looked at the importance of infant directed speech in babies’ language acquisition, the learning of new segments of language. This study specifically showed that the pitch and tone characteristics present in infant directed speech affect the way babies are able to tell the difference between different vowel sounds. The researchers concluded with this study that the exaggeration of pitch in IDS helps with vowel discrimination however the high pitch of IDS does not, instead aiding in emotional communication and gaining the baby’s attention. This shows how important IDS can be in babies learning of language as well as babies understanding of emotion (Source).

 

Our Current Study

The baby will sit on their parents lap while two cartoons are placed on a screen, one that talks with IDS and one with ADS. Throughout the study we will track the baby’s eye movement to see which cartoon the baby favors, the IDS one or the ADS one. To accurately discern which the baby truly likes more we are using an eye-tracking technology to follow which cartoon the baby looks at longest. We will also be recording the study to see the overall reaction of the baby to both types of speech and see which they tend to prefer based on their body language and facial expressions.

Natasa goes to Japan!

In mid-April 2019 Natasa Ganea, a PhD student in Goldsmiths InfantLab, will be going to Chuo University in Tokyo, Japan for 6 weeks.  Thanks to funding from the Economic and Social Research Council, she will have the chance to run a rare cross-cultural study on what babies know about gender.

About the study

Natasa wants to find out how babies perceive the gender of faces and voices. Infants will watch videos showing a woman and a man speaking in synchrony, side-by-side. As the infants watch the videos, they will hear a single female or male voice in the background. Natasa wants to know if they will match the gender of the voice to the correct face. She also wants to know if this is harder for faces of a different culture.

Will babies match the gender of the voice they hear to one of two faces on the screen?

Some infants will watch pairs of Caucasian-British speakers reading in English. Other infants will watch pairs of Asian-Japanese speakers reading in Japanese. Natasa predicts the task will be easier with faces from their native Japanese culture. When Natasa returns to the UK she will run the same study with British babies. She expects the pattern to reverse.

This is the final study of Natasa’s PhD which is all about how babies combine information from different senses to understand the world.

This is also the second collaboration between Chuo University and Goldsmiths InfantLab. Between 2016 to 2018, Jiale Yang a researcher from Chuo University visited Goldsmith’s InfantLab. Jiale and other members of the Yamaguchi Lab will help Natasa conduct the study.

Babies teach Developmental Psychology class

On Friday January 25th a mum and two babies (9 months and 23 months) visited our BSc Psychology 2nd year class in Developmental Psychology. The babies played games that are designed to show how they are learning new skills. We performed aspects of standardized tests called the Mullen Scales of Early Learning.

A special thank you to Claire and her children for helping with this class and to our PhD student Natasa for playing all of the games! Check out the videos below of the babies time in class!

In the second video Claire explains her choice to raise her children gender neutral. This discussion begins at around the 29 minute mark.

The Mullen Scales are a set of games that each focus on a different area: Gross Motor (standing, walking, crawling), Visual Reception (matching objects, noticing the difference between objects) Fine Motor (picking things up, building things from toys), Expressive Language (how babies express themselves through language) and Receptive Language (language understanding). These tasks attempt to assess the cognitive and motor abilities of children (specifically from 2 months to 45 months) and is generally used for seeing if children are intellectually ready to go to attend school.

What it’s like to be an InfantLab intern

Our EUSA intern Emily Peachthong

Emily Peachthong, EUSA intern from Boston Univeristy

Being an intern here at the InfantLab at Goldsmiths University of London has been an extremely unique experience for me. Not only was this my first internship in a new country outside of my native one, but it was my first internship ever. I went into this experience with a lot to expect, in terms of cultural differences and what it’s like to be an intern. However, I also went into this experience with a lot unexpected as well. By the end of my internship at InfantLab, I can confidently say that I was completely satisfied with my experience here.

I was kept busy every day with a variety of tasks to complete. Almost every day, I was in the lab with my colleagues and with some of the cutest babies I have ever seen. I got to observe and assist in various capacities in different studies being conducted at the time. I learned so much as an observer, from how to prepare the equipment involved in testing to how to comfortably interact with the babies. As an intern in the lab, I was completely comfortable with the tasks I was given. I had roles that were within my capability, and roles that led me to learn and grow in my skills. Plus, getting to hang out with babies is always an added bonus. I spent a lot of time in the lab getting to play with baby toys and blow bubbles, and I can assure that it’s always a good time.

In addition to assisting during testing, I also spent a significant amount of time in the lab recruiting parents and their babies to take part in our studies. Quite frankly, this was one of my favorite roles in the lab because the more time that passed with my being there, the more I learned how to meet the needs of the lab in an organizational way. I learned along the way that there is a lot to keep in mind when booking babies for the lab: correct age group; how to reflect the needs of the studies; how to comfortably and appropriately talk to parents; etc. This was one of my favorite tasks at InfantLab because not only did I gain a practical skill in recruiting participants, but it certainly helped in strengthening my organizational skills as well.

Another huge component of my time as an intern involved editing and redesigning the InfantLab’s website. This task involved changing around color and photos, and reshaping the organization and hierarchy of pages within the website. I’ve never taken on a role like this before at a job in the past. It was challenging at times, but also an educational and creative role that I engaged in. I am proud of the final product, and it is nice to know that I have this tangible piece of work to look back on of my time here at InfantLab.

There are so many more aspects of my internship at InfantLab that I truly appreciate. I was involved in the studies being conducted, and in future projects that were in their beginning stages. I got to read many interesting research papers. I even worked closely with MIT in preparation for an online study. Most of all, one of the biggest aspects of InfantLab that I appreciated was the very lovely community that made up the team. Everyone at InfantLab was friendly, and always willing to answer my questions and to teach me something new. I’m extremely grateful for how welcoming everyone made me feel. InfantLab was an incredible experience to embark upon during my time in London, and I wish any future intern or any member to have as great a time as I did!

 

Emily Peachthong was InfantLab intern from October to December 2018. She came to us through the EUSA internship program www.eusainternships.org.

The Baby Talk Study

All over the world, when people talk to babies we all use a very similar tone of voice. We raise our pitch and change our intonation in ways that sounds happier and more excited. Researchers have found infant directed speech (IDS) has a distinctive change in vocal timbre that is similar across many languages. This appears to help babies learn language because they make it easier to separate individual words and make key vowel sounds more distinctive. Researchers agree that emotional content and intonation both matter when speaking to babies but the relative importance of these elements is not known.

The aim of the present study is to learn more about baby talk. We are working with JJ Aucouturier and his team from IRCAM, Paris who are specialists in emotion in music and speech signals in adults. They have developed audio filters that can manipulate the ‘smileyness’ and other emotional aspects of a speech signal. We will use their software to manipulate recorded speech and see what version babies prefer.

Sounding Shapes

Many objects in the environment produce sounds as they move. This has been found to help infants learn the trajectory of objects even when the objects briefly disappear from sight, as is the case when an object moves behind an occluder. For example, when infants both see and hear a ball moving sideways behind a box they anticipate more often where the ball will reappear, than when the ball is moving but the sound appears to be coming from the static box. To what extent infants encode better objects that produce sounds as they move, or they simply track better the location of such objects, is a question that we are trying to answer in this study.

To do this, we are showing infants different geometrical shapes that move sideways behind an occluder while accompanied by different sounds, and record the interval of time that infants spend watching the animations. We are currently inviting 4 to 5 month old infants to take part in this study.

What Material Is It Made From?

As adults, we can recognize both what an object is and what material it is made of. In order to identify the material category to which an object belongs (e.g., metal, ceramic, fur, etc.), we have to obtain information about the physical properties of the object via multiple sensory modalities (e.g., vision, hearing, touch), and integrate this information in the brain. There is a large amount literature describing the development of infants’ ability to recognize objects (e.g. faces), but far less is known about the development of material recognition.

With this study, we would like to find out how infants process information about material via vision and touch. We will show your child several small metal cylinders, some of which have been covered with faux fur (see picture), and we will allow him/her to either manually explore or look at the cylinders. How your child explores and watches the cylinders will be videotaped. These recordings will allow us to investigate the extent to which babies distinguish different kinds of materials. We are currently inviting 4 to 8 month old infants to participate in this project.

Tickling Lights

If we feel a touch on one of our hands, it draws our attention to that hand. When we record adults’ brain activity whilst we flash a light on either the hand that they are paying attention to, or the hand that they are not, we see a difference in how the brain processes that flash of light. Paying attention to something causes a much larger brain response than if our attention is elsewhere. Little is known about this process in infants. By recording your child’s brain activity (using a special cap), we are able to focus in on the parts of the brain that process vision and touch and explore how infants process this kind of information.

In our study, we want to find out how young infants’ brain responds to light vibrations (that feel like slight tickles) on their hands which signal the location of a flash of light presented moments later (placed on the back of their hands via scratch mittens). We are currently inviting 7 and 10 month old infants to participate in this project.
