Millisecond Software thanks Dr. Zayas for sharing her script!


This script implements a sequential priming paradigm that assesses positive and negative evaluations elicited by significant others.

The script is based on:

Zayas, V. & Shoda, Y. (2015). Love you? Hate you? Maybe it's both: Significant persons trigger bi-valent priming. 
Social Psychological and Personality Science.

Fazio, R., Sanbonmatsu, D., Powell, M., & Kardes, F. (1986). On the automatic activation of attitudes. 
Journal of Personality and Social Psychology, 50, 229–238. 

After seeing a prime word (either a neutral word such as 'chair' or the name of the current significant other)
participants are asked to categorize adjectives as positive or negative using the 'E' and 'I' key on their

The default data stored in the data files are:

(1) Raw data file: 'significantotherSPP_raw*.iqdat' (a separate file for each participant)*

date, time:						date and time script was run
script.elapsedtime:				time it took to run script (in ms)
group:							the assigned groupnumber
									odd groupnumbers run Version 1 [Unpleasant (on the left) vs. Pleasant (on the right) (Neutral Word: Table)]
									even groupnumbers run Version 2 [Pleasant (on the left) vs. Unpleasant (on the right) (Neutral Word: Chair)]

subject:						the assigned subject number
blockcode, blocknum:			the name and number of the current block
trialcode, trialnum: 			the name and number of the currently recorded trial
									(Note: not all trials that are run might record data but they will still be reflected by trialnum; 
									by default data is collected unless /recorddata = false is set for a particular trial/block) 
response:						the participant's response (scancode of response key)
									18 = E 
									23 = I
correct:						accuracy of response: 1 = correct response; 0 = otherwise
latency: 						the response latency (in ms); measured from: onset of target

stimulusitem1:					for the practice/test trials: contains the prime word
stimulusitem2:					for the practice/test trials: empty
stimulusitem3:					for the practice/test trials: contains the target word

* separate data files: to change to one data file for all participants (on Inquisit Lab only), go to section
"DATA" and follow further instructions


Version EXPT 1: UP: Unpleasant (on the left) vs. Pleasant (on the right) (Neutral Word: Table)
Version EXPT 2: PU: Pleasant (on the left) vs. Unpleasant (on the right) (Neutral Word: Chair)
Note: Participants are assigned to each version by groupnumber selection

*** Primes are partner name and neutral word. Target stimuli are pleasant/unpleasant words.  
BLOCK 3 = practice (16 trials) Note: practice is repeated if mean response time > 1500ms and/or accuracy < 0.8
BLOCK 4,5 = DATA (80 trials each, in total 160 - 40 for each critical block, 
i.e., partner-pleasant, partner-unpleasant, neutral-pleasant, neutral-unpleasant) 

PRIME (200MS), PAUSE (100MS), TARGET WORD (until response)
