40. Nested Lists（2）
For the Stimulus attribute, the experiment resolves the
value of [Word] using the value obtained from the nested
List, and the Stimulus attribute is set to “dog.”

42. Sampling mode（1）
• Sampling modes include sequential, random
(without replacement), random (with
replacement),counterbalance, offset, and
permutation

51. 3:添加组块 （Block）
– Use a block level attribute to set a parameter of
an object executed in the trial procedure (the
PrimeDuration) 同样的程序，同样的刺激，不同
的刺激属性
– Use of nested lists passed from the block level
同样的程序，不同的刺激
– Use of block Procedure to pass in the trial
Procedure 同样的刺激，不同的程序
– 第一种方法trial直接调用Block。后两种方法Block都是
作为trial和其它表格联系的桥梁。不同的是，前者的表
格之间是嵌套关系，trial中有Attribute是通过其嵌套
的表格来赋值的；而后者的表格之间没有嵌套关系，
trial中的Attribute不需要被调用的表格来赋值 -HBF, IPCAS

53. 4:测试（1）
• Run experiment to verify correct and error responses
• Checking scoring and data collection
• Checking timing accuracy
• Running pilot subjects
– Verifying the understanding of instructions
– Checking the data

54. 4:测试（2）
• Run experiment to verify correct and error responses
– 正确反应
– 错误反应
– 无效反应
– 没有反应

56. Stage 8: 运行实验
• Running subjects
• Running on multiple machines
– Subject Station installation

57. 4: 基本数据分析
• Merging data
– Standard Merge vs. Recursive Merge operation
• Checking data condition accuracy and data
quality [Data editing Tracking modifications]
– the checking at this point is more in reference
to the completeness and appropriateness of the
data, the experimenter’s assignment of subject
numbers, and assignment of subjects to
conditions.
• Analysis and export of data

65. Event vs. Cumulative
Event Mode Timing – 刺激的呈现时间固定，刺激之间的间隔变化。
Cumulative Mode Timing – 两个刺激的起始时间之间的间隔不变，刺激的
呈现时间变短.

69. 不同实验设计与
调整时间精度的方法
• Single stimulus event to response timing,
– 仅仅需要精确记录单个刺激的持续时间和被试的反应时间
– Event mode without PreRelease
• Critical sequence of events,
– 刺激的持续时间和刺激之间的间隔都很重要
– Event mode with PreRelease. Duration accord refresh rate.
• Critical and varying duration of an event in a sequence,
– 变化的刺激持续时间.
– Event mode with PreRelease; list; Duration accord refresh rate
• Cumulative timing of a repeating sequence of events,
– 固定的/精确的呈现频率 重复的任务，
– Cumulative with PrePelease; 前后
• Continuous sequences of events at a high rate with short stimulus
