Raw Data from Experiment 2 of Kahana & Caplan (2002). Experiment code is SL5''.

Introduction

• data_info (specs. for the current data block)
• data_format (format for the current data block)
• data (the data, in rounds)

Header

• gbk_version- version of the GBK data file format used.
• experiment- not used
• experiment_version- 3.0 (means SL5'')

Serial Learning blocks

data_info

• subject- the subject's unique id
• list- the list number (zero-based). NOTE: practice lists are available but not included in the main data files.
• phase- 1 for serial learning phase.
• sorted_pool- the complete noun pool used in the experiment, sorted alphabetically, in text separated by spaces
• shuffled_pool- the shuffling of the noun pool used for this subject. Indices refer to the ordinal position within the sorted pool (zero-based).
• word_list- the current word list to be learned, in text
• list_serial_positions- the current word list to be learned, in indices based on the sorted word pool (note: you should be able to find these sequences within the shuffled_pool field)

data_format

• trial- The first line in each round of the data block will refer to the trial number (one-based)
• response- The second line in each round of the data block will contain the responses, in indices based on the sorted word pool (zero-based). NULL terminated and padded with NULLs.
• reaction_time- The third line in each round of the data block will contain the interresponse (NOTE: inter-response times, not absolute start times) for each of the corresponding response from the response field. NULL terminated and padded with NULLs.

Cued Recall blocks

data_info

• subject- the subject's unique id
• list- the list number (zero-based). NOTE: practice lists are available but not included in the main data files.
• phase- 2 for cued recall phase.
• cue_blocks- the current word list to be learned, in text, with vertical lines (|) denoting where the cueing block boundaries were drawn. Thenceforth, cue block 0 refers to the words preceding the first |, block 1 refers to the words between the first and second |, and so on.
• cue_blocks_serial_positions- the current word list to be learned, in indices based on the sorted word pool (note: you should be able to find these sequences within the shuffled_pool field). This also contains vertical lines denoting cue block boundaries.

data_format

• cue_level- the list was cued completely twice. Therefore, this will either have the value of 0, for the first complete cueing, or 1, for the second full cueing.
• cue_sequence- the order in which the cues were presented (zero-based). The first number denotes which cue block was probed first. The second number denotes which cue block was probed second, etc.
• cue_types- For each block (list order, not probe order), the cue type presented. Note that for pair blocks, only 0 and 1 are allowed, and for triple blocks, only types 2-6 are allowed. The cue types are as follows:
  • 0: A?
  • 1: ?B
  • 2: AB?
  • 3: ?BC
  • 4: A?C
  • 5: A_?
  • 6: ?_C
• response- the responses to each cue block (in list order, not presentation order). Each response consists of a letter followed by a number:
  • C- correct (followed by the target item index)
  • L- within-list intrusion (followed by the item index for the intruded item)
  • <- prior-list intrusion (followed by the item index for the intruded item)
  • P- intrusion from the noun pool, but an item that hasn't yet been presented; note that this is just coincidental and in every way should be considered like a regular intrusion (followed by the item index for the intruded item)
  • !- intrusion not in the noun pool (followed by the word in text)
  • N- no response (like a pass or a blank), followed by a 0 as a place-holder.
  • 0- machine failure (i.e., you should exclude these from any analyses), followed by a 0 as a place-holder.
