Code and data for Wispinski et al. (2021)

Wispinski, N.J., Lin, S., Enns, J.T., & Chapman, C.S. (2021). Selective attention to real-world objects drives their emotional appraisal. Attention, Perception, & Psychophysics. https://doi.org/10.3758/s13414-020-02177-x.

This project consists of two experiments which aimed to measure the impact of attention and action on affective evaluation.

These data and code (along with pre-registration and videos of the task), are also available at https://osf.io/iyd9s/.

Prerequisites

This code is written to be compatible with MATLAB 2018a.

Data

Data

• Contains a .mat file for each participant
• Participant ID prefixes correspond to study and condition:
  • OD (Study 1)
  • OR (Study 2 - Reaching condition)
  • OK (Study 2 - Keyboard condition)
• Note: Some participant IDs are repeated because of experimenter error. All individual files correspond to a unique participant-condition combination
• data_struct.matData contains trial-by-trial behavioural measures (variables described in .m analysis scripts)
• data_struct.newFDA contains space-normalized (100 points per trial) reach trajectories for each trial (see Gallivan & Chapman, 2014 for trajectory analysis methods)

Code

Study1_Analysis_Feb2019.m

• Analyses Study 1 (OD* files) for effect of attentional condition on affective ratings

Study2_Analysis_Feb2019.m

• Analyses Study 2 (OR* and OK* files) for effect of attentional condition on affective ratings

removeTrials.m removeTrials_keyboard.m

• Functions to remove trials from reaching or keyboard data based on trial indices
• Called by analysis scripts Study1_Analysis_Feb2019.m and Study2_Analysis_Feb2019.m

reachExampleFig.m

• Generates figure 1d (example 3D reach trajectories in Study 2)

drawTest.m

• Generates "circles", "shape", and "squares" stimuli used in Studies 1 and 2 on a small Psychtoolbox screen
• Uses functions:
  • drawCircles.m
  • drawPoly.m
  • drawSquares.m
