Top-down vs. bottom-up listening
Imagine the following situations:
Over lunch, your friend tells you a story about a recent holiday, which was a disaster. You listen with interest and interject at appropriate moments, maybe to express surprise or sympathy.
That evening, another friend calls to invite you to a party at her house the following Saturday. As you’ve never been to her house before, she gives you directions. You listen carefully and make notes.
How do you listen in each case? Are there any differences? With the holiday anecdote, your main concern was probably understanding the general idea and knowing when some response was expected. In contrast, when listening to the directions to a party, understanding the exact words is likely to be more important – if you want to get there without incident, that is!
The way you listened to the holiday anecdote could be characterised as top-down listening. This refers to the use of background knowledge in understanding the meaning of the message. Background knowledge consists of context, that is, the situation and topic, and co-text, in other words, what came before and after. The context of chatting to a friend in a casual environment itself narrows down the range of possible topics. Once the topic of a holiday has been established, our knowledge of the kind of things that can happen on holiday comes into play and helps us to ‘match’ the incoming sound signal against our expectations of what we might hear and to fill out specific details.
In contrast, when listening to directions to a friend’s house, comprehension is achieved by dividing and decoding the sound signal bit by bit. The ability to separate the stream of speech into individual words becomes more important here, if we are to recognise, for example, the name of a street or an instruction to take a particular bus.
In reality, fluent listening normally depends on the use of both processes operating simultaneously. Think about talking to your friends (in your first language) in a noisy bar. It is likely that you ‘guess’ the content of large sections of the conversation, based on your knowledge of the topic and what has already been said. In this way, you rely more on top-down processing to make up for unreliability in the sound signal, which forms an obstacle to bottom-up processing. Similarly, second-language listeners often revert to their knowledge of the topic and situation when faced with unfamiliar vocabulary or structures, so using top-down processing to compensate for difficulties in bottom-up processing. On the other hand, if a listener is unable to understand anything of what she hears, she will not even be able to establish the topic of conversation, so top-down processing will also be very limited.
In real-life listening, our students will have to use a combination of the two processes, with more emphasis on top-down or bottom-up listening depending on their reasons for listening. However, the two types of listening can also be practised separately, as the skills involved are quite different.
Top-down listening activities
Do you ever get your students to predict the content of a listening activity beforehand, maybe using information about the topic or situation, pictures, or key words? If so, you are already helping them to develop their top-down processing skills, by encouraging them to use their knowledge of the topic to help them understand the content. This is an essential skill given that, in a real-life listening situation, even advanced learners are likely to come across some unknown vocabulary. By using their knowledge of context and co-text, they should either be able to guess the meaning of the unknown word, or understand the general idea without getting distracted by it.
Other examples of common top-down listening activities include putting a series of pictures or sequence of events in order, listening to conversations and identifying where they take place, reading information about a topic then listening to find whether or not the same points are mentioned, or inferring the relationships between the people involved.
