6 <p>This experiment will consist of 28 short melodies presented in two
|
|
m@5
|
7 blocks. The first block contains 2 practice trials for you to
|
|
m@5
|
8 familiarise yourself with the programme. After the practice block, you
|
|
m@5
|
9 will be able to adjust the volume to a comfortable level and ask any
|
|
m@5
|
10 questions you may have. The main part of the experiment will follow on
|
|
m@5
|
11 from the pracice block.</p>
|
|
m@5

12
|
|
m@5
|
13 <p>When each melody starts playing, a cross will appear in the centre
|
|
m@5
|
14 of the screen. You should focus on this cross while listening to the
|
|
m@5
|
15 melody.</p>
|
|
m@5
|
16
|
|
m@5
|
17 <p>Whilst listening to each melody, you will be prompted to judge how
|
|
m@5
|
18 expected or unexpected you find a given note. Shortly before such
|
|
m@5
|
19 notes, the cross will be replaced by a clock with a minute hand at 12
|
|
m@5
|
20 O'Clock. The hand will count down in time with the music. The note
|
|
m@5
|
21 whose onset coincides with the hand returning to 12 O'Clock is the one
|
|
m@5
|
22 you should respond to. </p>
|
|
m@5
|
23
|
|
m@5
|
24 <p>You should judge how expected or unexpected you find a given note
|
|
m@5
|
25 in the preceding context of the melody using a scale of 1 (highly
|
|
m@5
|
26 unexpected) to 7 (highly expected). Please try to use the full range
|
|
m@5
|
27 of the scale.</p>
|
|
m@5
|
28
|
|
m@5
|
29 <p>The music will continue to play, so try to respond as quickly as
|
|
m@5
|
30 possible, however accuracy is more vital than speed. There is only one
|
|
m@5
|
31 chance to make your decision, once selected it cannot be
|
|
m@5
|
32 changed. Before making your judgement, try to keep the mouse pointer
|
|
m@5
|
33 in the midrange of the scale (i.e., 4).</p>
|
|
m@5
|
34
|
|
m@5
|
35 <p>After listening to each melody, you will be required to answer some
|
|
m@5
|
36 short questions relating to the music before listening to the next
|
|
m@5
|
37 piece.</p>
|
|
m@5
|
38
|
|
m@5
|
39 <p>If you have any questions please ask now. Otherwise, press
|
|
m@5
|
40 'Continue' to move directly to the practice block</p>
