Two experiments were performed with experienced sonar |
|
technician listeners in an effort to identify perceptual |
|
dimensions underlying the classification of aurally |
|
presented sonar signals. It was found that: (1) where |
|
common sets of sonar signals are used as stimuli, the |
|
group perceptual space of naive and experienced sonar |
|
listeners is highly similar; (2) experienced sonar |
|
listeners attach different salience or importance to |
|
particular dimensions than do naive listeners; (3) the |
|
number of dimensions in the group perceptual space is a |
|
function of the representativeness of the signal set; (4) |
|
most sonar signals are quite complex perceptually, and |
|
project on several dimensions; (5) very strong |
|
projections on some of the experimentally identified |
|
dimensions are associated with a high degree of |
|
classification success, but signals that lack strong |
|
projections on any dimension are often erroneously |
|
classified; (6) experienced sonar listeners classify |
|
signals in accord with how strongly the signals resemble |
|
certain target class stereotypes; this may or may not |
|
result in successful classification of particular |
|
examples. |
