In this experimental study, various software and hardware were used during data collection and analysis of data. All the experimental tasks were designed using E-Prime software, which was connected with the EGI Net Station data acquisition software during data collection to synchronize the events recording in E-Prime as well as in the EEG recordings. The EEG data was collected with EGI 128-sensor cap and ECG with two sensors connected to a polygraph. The EEG and ECG data can be exported to third party software such as MATLAB or Neuroguide for further analysis. EEG signals were preprocessed in EGI Net Station software and post- processed in Neuroguide software. The ECG signals were processed in MATLAB using Biosignal Toolbox.

The following software and hardware were used in this study for experiment design, data collection, and data analysis:

  • 1. E-Prime 2.0 (for experiment design in how to present stimulus to the subject)
  • 2. Electrical Geodesics, Inc. (128-channel EEG equipment with Net Station software)
  • 3. MATLAB 2010 (for simulation)
  • 4. Biosignal Toolbox
  • 5. Neuroguide software
  • 6. Statistical Package for Social Sciences (SPSS) for data analysis E-Prime: E-Prime 2.0 is a psychology software for stimulus presentation in cognitive and behavioral research experiments (http://www. This software is widely adopted in neuroscience research for stimulus presentation, control, and recording behavioral responses. It allows the users to control time synchronization of stimulus onset, offset, subjects’ responses, and the corresponding EEG data. All the tasks used during this dataset are explained in the experimental design section. Details on each task in the E-Prime program are provided in the data description section.

EGI 300 amplifier & EEG nets: The hardware including the EEG nets and amplifier are from EGI Inc. ( The EEG net contains 128 channels for recording of dense-array EEG from all over the scalp surface locations.

Net Station: Net Station is an EEG acquisition software that is used for recording EEG signals during learning and memory tasks. Net Station allows connection with the E-Prime software during running of the experiments for synchronization of time information for stimulus and subjects’ responses. The raw EEG recording can be processed in Net Station, and includes processing operations such as filtering, segmentation, rereferencing, and exporting data to several other formats, e.g., .edf or .mat.

MATLAB: MATLAB is a high-performance programming language for technical computing and coding for engineering problems. It provides an integrative environment for use by engineers and scientists worldwide. The easy-to-use programming environment of MATLAB provides fast solutions to complex mathematical problems. The well-known disciplines of MATLAB programming are signal and image processing, communications and control systems, computational neuroscience and GUI programming, pattern recognition, and machine learning. For beginners in neuroscience, the book MATLAB for Neuroscientists by Pascal Wallisch and colleagues can be consulted.

BioSignal ToolBox: BioSignal ToolBox ( help/index.html) is a collection of MATLAB functions for analysis of physiological signals including EEG and ECG.

Neuroguide: Neuroguide is EEG analysis software developed by Applied Neuroscience Inc. ( in the United States. The software is well known for the analysis of qEEG data and generating participants’ relative reports with respect to an EEG normative database.

Statistical Package for Social Sciences (SPSS): The SPSS was initially designed for social science problems by IBM. However, the software now includes many machine-learning algorithms such as clustering and classification. The SPSS is widely accepted for statistical analysis in disciplines including engineering and neuroscience.
