How Exposure to Foreign Language in Infancy Can Aid Phonetic Learning

Exposure to foreign language early on can aid future language learning.

As we explored last week, foreign language development declines rapidly after the first year of infancy.

This is when mind-mapping of language is set, and recognition of foreign sounds becomes “interference.”

But before a year, an infant’s mind can map foreign languages in a way that can help them identify foreign sounds.

In an experimental demonstration of phonetic learning, University of Washington neuroscientist Patricia Kuhl has found that American infants exposed to Mandarin Chinese were able to differentiate between its phonetic elements, but only through social interaction with a human.

The Experiment: “Chee” and “She” 

The Mandarin sounds, “chee” and “she,” are difficult for adult Americans to differentiate.

A pair of studies tested whether infants could distinguish between the two.

In the initial study and the first experiment of its kind, 9-month-old American infants were exposed to Mandarin for less than five hours in a laboratory setting.

Over the course of a dozen 25-minute sessions spanning four weeks, four native speakers – two women and two men – read children’s books in Mandarin and played with the children while speaking.

An English control group did the same.

The infants in the Mandarin group showed an ability to distinguish between the language’s sounds, much more so than those in the control group.

The Mandarin group’s ability to discern between “chee” and “she” was also shown to be equivalent to that of a group of Taiwanese infants exposed to Mandarin for ten months. 

The infants’ ability to differentiate between the sounds lasted for 12 days – and maybe longer, as Kuhl is currently retesting and analyzing months later.

This indicates that short-term exposure to foreign language in infancy can significantly improve foreign language speech perception and retention.

Socializing Companion Study

A companion study exposed a second group of American infants to Mandarin using audiotape and DVD.

The children in this study showed no ability to distinguish between the sounds, revealing that phonetic learning is better learned and retained through social exposure.

Audio and DVD did not offer the same stimulation as a live human. 

In a presentation of the studies’ findings at the American Association for the Advancement of Science, Kuhl said:

“The findings indicate that infants can extract phonetic information from first-time foreign-language exposure in a relatively short period of time at 9 months of age, but only if the language is produced by a human, suggesting that social interaction is an important component of language learning.”

Kuhl also notes that the 9-month period is a sensitive window for language learning, emphasizing the importance of timing.

She also highlighted other aspects of infant abilities in language learning, including:

“…their attraction to ‘motherese’ (a form of exaggerated speech) spoken by adults to babies; the statistical learning that infants engage in by analyzing language; and the ability to follow the gaze of another person to an object to understand what they are talking about.”

Food Culture: What HOW You Eat Can Tell You About Culture

Do you eat your dinner at the dining table, or do you eat sitting crosslegged on the floor?

Do you share a communal dish of food, or does everyone have an individual plate?

What utensils do you use – a fork, spoon, and knife; chopsticks; your hands?

With whom do you eat? Family, friends, with only your own gender?

The answers to these questions are part of your food culture – and to a larger extent, your culture as a whole. 

On the surface, you see only the limbs of the baobab – the cultural norms – but the details of your food culture can tell you something deeper about the roots (i.e. your cultural values).

The Presentation: Food Plating

Another aspect of food culture is the amount of care put into food presentation.

One study delved into the differences between American, Italian, and Japanese food plating preferences.

Titled, “Looks Good Enough to Eat: How Food Plating Preferences Differ Across Cultures and Continents,” the study found that Japanese participants prefer more formally arranged plates, while Italians and Americans prefer more casually presented food.

The researchers concluded that this springs from the respective cultures’ individualist versus collectivist natures.

The Japanese are a collectivist culture, so formality and identical presentation may have roots in the Eastern collectivist tradition.

Italians and Americans are individualist Western cultures. Self-autonomy and informality, even in how one’s own plate is presented, may be rooted in this mindset.

The study also noted the fullness/emptiness of the plated food.

The Japanese and Americans’ plates were relatively empty, while the Italians preferred very full plates.

The researchers concluded that the preference for empty plates might be related to the Japanese and American ideal of open space.

How, When, Why, With Whom?

Food norms can tell you a lot about a culture, so when you’re trying to understand/learn a culture, consider these norms to understand the culture’s deeper values

Practice this with your favorite culture – or even your own.

Ask:

  • How often do you eat? How long do you take to eat? 

Many Mediterranean countries, for instance, spend hours dining each day, as sharing food is considered an important social event.

  • When do you eat?

The Spanish, for instance, eat dinner between 9 PM and midnight, and it’s a much lighter meal than lunch. This is historically linked to their afternoon siesta and being geographically located in the wrong time zone.

  • Why do you eat?

Some cultures tend to eat only for sustenance while others take more pleasure in eating.

  • With whom do you eat?

While eating is a family affair for most countries, for others this is not the case.

Answering these questions about food culture will help you understand that culture or learn something new. It will help you connect the dots between a culture’s norms and its values.

Americans vs. the Swiss: Defining Friendship

An American sits down beside a Swiss on an airplane. 

After some initial friendly banter (one-sided from the American), he asks, “Where are you off to?”

The Swiss, slightly uncomfortable, is reluctant to respond, but the American doesn’t take the cue.

Without prompt, he proceeds to share his entire trip with the Swiss. He was visiting his son who lives abroad in France. They went on a bike journey across the Baltics together. He’s now heading home to Minnesota, where he’s retired. He and his wife have three other kids, all of whom are newly out of the nest. Their absence has been particularly hard on him, and he’s been trying to find new hobbies – like biking – to fill that empty void where activities with his children once stood.

“Enough about me…” he wraps up. “What about you? What do you do?”

The Swiss squirms in his seat. This man is a stranger, and it’s none of his business. Even worse, the Swiss has nowhere to turn. The nonstop flight is eight hours. Would it be rude to put his headphones in?

This is a marked difference between American and Swiss culture.

Small talk is a common, acceptable, and even appreciated social norm in America.

In Switzerland, not so much.

Sharing Personal Info

This chart illustrates just how uncomfortable the above American just made his Swiss cohort.

The Swiss only share small talk with buddies or friends – and sometimes with colleagues.

In fact, the American went well past small talk, sharing non business related topics, personal factual information, and even personal emotional themes, all of which are only shared between close friends in Switzerland.

To breach this wall with a stranger can feel egregious to the Swiss.

As we talked about last week, respecting others’ privacy is highly valued in Swiss culture.

Their “bubble” is much larger than that of their American counterpart.

Comfort Zone of Communication

The comfort zone of communication is considerably tighter in Switzerland and the scope of people with whom they communicate narrower.

Americans talk about anything and everything with their friends and are, more often than not, comfortable sharing more with a broader range of people as well, whether they be acquaintances or even strangers on a plane.

Swiss view friendship as intimate and permanent. Being a friend means being there, through thick and thin; it’s a life-long commitment not to be taken lightly.

Essentially, the Swiss have no “degrees” of friendship; they have a single solid unalterable definition.

Americans, on the other hand, have a wider range of friendships. They might have people they consider close friends who always have their back, others they consider fun and easygoing buddies who come and go from their lives, and still others with whom they’d be happy to grab a beer and discuss politics but not necessarily share their deepest darkest secrets.

While Americans might view “close” friendships similarly to the way the Swiss view friendship in general, they are also more often open to lighthearted, casual friendships with most anyone.

To some, they might be considered “fair-weather friends,” while to others with whom they are more intimate, they are considered loyal.

But they are willing to share degrees of themselves and their lives with even strangers, all the same.

So, how does one make friends in a culture with such a different concept of friendship?

We’ll bridge that gap next week.

How Culture Impacts a Person’s Sense of Control (aka Locus of Control)

Do you believe in fate?

Last week, we talked about how the degree to which someone feels life is directed by destiny dictates their locus of control – that is their feeling of control over their own lives.

Let’s look at how the locus of control unfolds in the workplace.

The Blame Game

When a goal is set and not reached in a workplace environment, the reactions of your colleagues can be very telling.

Sheila blames Jeremy for not delivering the documents in time for her to complete her task.

Jeremy blames Tom for not communicating promptly.

Tom blames his home life for distracting him.

Team Leader Lisa admits she missed the mark and should have taken the campaign in another direction. She apologizes for the part she played in not meeting the goal.

People with an internal locus of control take personal responsibility for their role in a group’s failure, while those with an external locus point at everyone else but themselves, whether they see fault in the “weakest links” of the group or in external factors.

Cross-Cultural Factors

How do cross-cultural factors come into play in the locus?

The locus of control is directly related to personality orientation; however, social psychologists have begun to study the majority locus of control in various cultures and the factors that influence it.

They’ve discovered that quite often the people of any given culture look at fate or self-control in a generally collective manner.

As you may have guessed, individualist cultures generally demonstrate an internal locus of control. They believe they’re the masters of their own fate.

Collectivist cultures – like those of China or Japan – demonstrate an external locus. They accept that things are out of their hands and don’t put weight on the individual’s role in the whole.

To illustrate this, when Americans and Chinese were surveyed about their view of fate, these were the results.

locusofcontrol

89% of questioned Americans agreed with the statement, “What happens to me is my own doing,” while 65% of Chinese admitted, “Sometimes I feel I don’t have control over the direction my life is taking.”

This aligns with each culture’s dominant traits, with Americans espousing ambition, individualism, and the “American dream,” while China espouses harmony and collectivism.

Next week, we’ll talk a little bit about how the group locus of control can be divided up further amongst ethnic groups and even simply locations in the same country. We’ll also talk about primary and secondary control. Stay tuned.
