The development of working memory

Overview of the Working Memory Case Study

This case study is provides an overview of the DF model used in Spencer (2020) Current Directions in Psychological Science. Here's a link to the paper (open access): https://journals.sagepub.com/doi/10.1177/0963721420959835

To start with, here's an introductory lecture on the area of visual working memory development and how we've used dynamic field models to shed new insights into a fundamental question: how does working memory capacity increase over development?

Next, I’ve recorded a brief video tour of the paper and DF simulator.

Setting up COSIVINA

To play around with the model from the paper, you will first need to set up the COSIVINA simulation environment. You can clone the COSIVINA repository from https://github.com/cosivina. For an overview of how to do this, see my video tour which includes details of how to use the GitHub Desktop App along with our DF respositories. For details, see:

In addition to COSIVINA, you'll need the simulator from the ‘Spencer_CurrDirPsychScience_2020” folder at: https://github.com/cosivina/cosivina_dft_projects

You'll also need to download the jsonlab support files: https://github.com/fangq/jsonlab

Running the Simulator

To play around with the model, launch matlab. Next, navigate to your COSIVINA folder and type 'setpath'. This will link in the core COSIVINA files and jsonlab support. Finally, go to the ‘Spencer_CurrDirPsychScience_2020” folder and run the ‘OneFieldBAM’ file in matlab. Comments in this file explain how to reproduce the figures from the paper.

For a detailed tour, you can watch my three tutorial videos (recommended in this order):

(1) Overview of the SIMulator (SIM) file

(2) Overview of the Graphical User Interface (GUI) file

(3) Overview of the Batch-Auto-Multicore (BAM!) file
