The Emotional Go/No Tasks leverages this paradigm to investigate emotion processing, especially emotion recognition and emotion regulation. The implemented procedure is based on: Tottenham, N., Hare, T.A. & and B. J. Casey, B.J. (2011). Behavioral assessment of emotion discrimination, emotion regulation, and cognitive control in childhood, adolescence, and adulthood. Frontiers in Psychology, doi: 10.3389/fpsyg.2011.00039. ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Participants view images of fearful/happy/sad/angry or neutral facial expressions and are asked to Condition 1: press the spacebar when they see a fearful face ("go") and only then (nogo images: neutral faces) Condition 2: press the spacebar when they see a neutral face ("go") and only then (nogo images: fearful faces) Condition 3: press the spacebar when they see a happy face ("go") and only then (nogo images: neutral faces) Condition 4: press the spacebar when they see a neutral face ("go") and only then (nogo images: happy faces) Condition 5: press the spacebar when they see a sad face ("go") and only then (nogo images: neutral faces) Condition 6: press the spacebar when they see a neutral face ("go") and only then (nogo images: sad faces) Condition 7: press the spacebar when they see a angry face ("go") and only then (nogo images: neutral faces) Condition 8: press the spacebar when they see a neutral face ("go") and only then (nogo images: angry faces) ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 10 minutes to complete ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'emotionalgonogo_raw*.iqdat' (a separate file for each participant)* build: The specific Inquisit version used (the 'build') that was run computer.platform: the platform the script was run on (win/mac/ios/android) date, time: date and time script was run subject, group: with the current subject/groupnumber session: with the current session id blockcode, blocknum: the name and number of the current block (built-in Inquisit variable) trialcode, trialnum: the name and number of the currently recorded trial (built-in Inquisit variable) Note: trialnum is a built-in Inquisit variable; it counts all trials run; even those that do not store data to the data file. (Note: not all trials that are run might record data; by default data is collected unless /recorddata = false is set for a particular trial/block) condition: practice, NF, FN, NH, HN, NS, SN, NA, AN (first letter = go stim; second letter = nogo) GoFaces: "NEUTRAL" vs. "FEAR" vs. "happy" vs. "SAD" vs. "ANGRY" (current go faces) NogoFaces: "NEUTRAL" vs. "FEAR" vs. "happy" vs. "SAD" vs. "ANGRY" (current nogo faces) iti: current intertrial interval (default: 0) image: the presented image response: the participant's response: Scancode of response key 57 = spacebar 0 = no response (21 = Y; 49 = N) correct: accuracy of response: 1 = correct response; 0 = otherwise response_outcome: go trials: HIT (correctly pressing response key), MISS (response key was not pressed); nogo trials: FA (false alarm = incorrectly pressing response key), CR (correct rejection: response key was not pressed) latency: the response latency (in ms) of the current trial (does not have to be a go, nogo trial) response_time: response time (in ms) of current practice and test go/nogo trials, measured from onset of image (Note: if no response, 'RT' is empty) (2) Summary data file: 'emotionalgonogo_summary*.iqdat' (a separate file for each participant)* inquisit.version: Inquisit version run computer.platform: the platform the script was run on (win/mac/ios/android) startDate: date script was run startTime: time script was started subjectid: assigned subject id number groupid: assigned group id number sessionid: assigned session id number elapsedTime: time it took to run script (in ms); measured from onset to offset of script completed: 0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run) Note: this script does not remove outliers Note: the following expressions calculate z-scores based on hit and FA rate.(see Gregg & Sedikides, 2010, p.148) If the hit rate / FA rate is 0 => 0.005 is used instead IF the hit rate / FA rate is 1.0 => 0.995 is used instead Reference: Gregg, A. & Sedikides, C. (2010). Narcissistic Fragility: Rethinking Its Links to Explicit and Implicit Self-esteem, Self and Identity, 9:2, 142-161 (p.148) hitrate: the overall hitrate across all blocks (hit = pressing space bar for go stimuli) missrate: the overall missrate across all blocks (miss = not pressing spacebar for go stimuli) FArate: the overall False Alarm rate across all blocks (FA = pressing space bar for nogo stimuli) CRrate: the overall Correct Rejection rate across all blocks (CR = not pressing spacebar for nogo stimuli) z_hitrate: the z-score of the overall hitrate z_FA: the z-score of the overall FA rate dprime: difference btw. (zscore of hitrate - zscore of FArate): measure of Sensitivity => Range (in this script): -5.1516586840152740479 <= dprime <= 5.1516586840152740479 (=perfect performance) => The higher the value, the better signals were overall distinguished from noise (d' = 0: chance performance; negative d-primes: participant treated nontargets as targets and targets as nontargets) c: c-criterion in signal detection:The absolute value of c provides an indication of the strength of the response bias/response style negative: participant more likely to report that signal is present (liberal response style); may favor faster responding in speed-accuracy trade-off response paradigms positive: favoring caution (conservative response style) mean_hitRT: the overall mean Hit response time (in ms) SD_hitRT: standard deviation of the Hit response times across blocks (in ms) ///////////////////// per conditions ///////////////////// hitrate_NF: the hitrate in NF block (go: positivehappy words, nogo: neutral words) missrate_NF: the missrate in NF block FArate_NF: the false alarm rate (commission rate) in NF block CRrate_NF: the correct rejection rate in NF block z_hitrate_NF: the z-score of the NF hitrate z_FA_NF: the z-score of the NF FA-rate dprime_NF: difference btw. (z_hitrate - z_FA) in NF block: measure of Sensitivity c_NF: c-criterion for block NF hitRT_NF: mean hit response time (in ms) in NF block (same for all other conditions) FArate_Emotions: Commission Errors for erroneously responding to Nogo Emotion stimuli => can be used a measure for Emotion Regulation (Tottenham et al, 2011, p.3), in this paradigm operationalized as the ability to inhibit responses to emotionally valanced stimuli. => The higher the commission rate, the lower the ability to regulate emotions. * separate data files: to change to one data file for all participants (on Inquisit Lab only), go to section "DATA" and follow further instructions ___________________________________________________________________________________________________________________ EXPERIMENTAL SET-UP ___________________________________________________________________________________________________________________ Practice: optional (see parameters.runPractice) * 10 trials (5 go, 5 nogo) * script uses item.practice as the go-stimuli (default facial expression: surprise) and neutral as no-go * provides feedback for 1000ms Test: 8 Conditions: order of conditions is randomly determined FN: go = fear; nogo = neutral (by default: fear faces are repeated twice after reset; neutral faces are repeated once) NF: go = neutral; nogo = fear (by default: neutral faces are repeated twice after reset; fear faces are repeated once) HN: go = happy; nogo = neutral (by default: happy faces are repeated twice after reset; neutral faces are repeated once) NH: go = neutral; nogo = happy (by default: neutral faces are repeated twice after reset; happy faces are repeated once) SN: go = sad; nogo = neutral (by default: sad faces are repeated twice after reset; neutral faces are repeated once) NS: go = neutral; nogo = sad (by default: neutral faces are repeated twice after reset; sad faces are repeated once) AN: go = angry; nogo = neutral (by default: angry faces are repeated twice after reset; neutral faces are repeated once) NA: go = neutral; nogo = angry (by default: neutral faces are repeated twice after reset; angry faces are repeated once) * Each condition runs 30 trials (20 go trials, 10 nogo trial); trial order of go-nogo trials is generated at random Note: this script runs 2/3 go trials, 1/3 nogo trials (Trottenheim et al al report 70%:30%) Trial Sequence: image (500ms) -> fixation cross (1000ms): response timeout after 1500ms -> iti = 0 (see list.iti) (iti presents fixation cross) ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ Trottenheim et al (2011, p. 2) used 10 adults (five females and five males) per facial expression. The stimuli used in this scripts are placeholder stimuli only. They can be edited under section Editable Stimuli. The placeholder stimuli have the same image names as the following NIMSTIMS for neutral (ne), happy (ha), sad (sa), fearful (fe) and angry (an) faces (all open mouth expressions) female: 2, 5, 13, 14, 18 male: 21, 23, 24, 41, 42 practice stimuli (surprise (sp) and neutral (ne) expressions) are stand-ins for: female: 1, 11, 15 male: 32, 39 NOTE: The NIMSTIMS image files need to be converted to *png files (or the *png extensions used in this script need to be converted to *bmp ) ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ provided by Millisecond Software - can be edited under section Editable Instructions ___________________________________________________________________________________________________________________ EDITABLE CODE ___________________________________________________________________________________________________________________ check below for (relatively) easily editable parameters, stimuli, instructions etc. Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment. The parameters you can change are: /fixationSize: proportional sizing of fixation cross (relative to canvas height) (default: 10%) /picSize: proportional sizing of images (relative to canvas height) (default: 50%) /runPractice: true: script runs a short practice session with item.practice as the go items false: script does not run a practice session /practiceFeedbackDuration: the duration (in ms) of the practice Feedback (default: 1000ms) /getReadyDuration: the duration (in ms) of the 'ready' trial (default: 5000ms) /startFixation: the duration (in ms) of the first fixation cross in a block (default: 2500ms) /endFixation: the duration (in ms) of the last (red) fixation cross in a block (default: 2000ms) /picDuration: the duration (in ms) of the images (default: 500ms) /responseDuration: the response timeout (in ms), measured from onset of image (default: 1500ms) /goKey: the go-key (default: " " = spacebar)
