Attentional Network Test
Category:Attention
Duration:~15 minutes
Parameters:7 configurable parameters available
Version:1.1
Input:Keyboard
Description
The PEBL Attentional Network Test (PANT) measures the efficiency of three attention networks: alerting, orienting, and executive control. Participants identify the direction of a central arrow while ignoring flanking arrows, with various cuing conditions to assess different attention components.
Key Parameters
| iti | Inter-trial interval, in ms. (default: 4000) |
| responsemode | Response method: auto (platform-aware), keyboardShift (L/R shift), keyboardSafe (Z/slash for web), mousetarget (click targets), mousebutton (L/R mouse buttons), userselect (choose your own keys) (default: auto) |
| responselabels | Semantic labels for left and right responses (default: Array) |
| showfooter | [DEPRECATED - footer now managed by layout system] Show/hide footer (default: 0) |
| leftresponse | [DEPRECATED - use responsemode instead] Left response key. Kept for backward compatibility. (default: <lshift>) |
| rightresponse | [DEPRECATED - use responsemode instead] Right response key. Kept for backward compatibility. (default: <rshift>) |
| reps | Number of repetitions through the design (which is 4 cue conditions x 2 target locations x 2 target directions x 3 flanker conditions (default: 2) |
| showRT | Show/hide reaction time display in practice block (ShowRT <- 0 == hide / gShowRT <- 1 == show) (default: 0) |
| showNeutralFlankers | Show/hide neutral flankers (dashs in the neutral condition) (gShowNeutralFlankers <- 0 == hide / gShowNeutralFlankers <- 1 == show) (default: 0) |
