Các quá trình giai đoạn nhận thức thần kinh trong hiệu suất bộ nhớ làm việc
Tóm tắt
Bộ nhớ làm việc (WM) được định nghĩa là việc duy trì chủ động và cập nhật linh hoạt các thông tin liên quan đến mục tiêu trong một hình thức có dung lượng hạn chế và chống lại sự can thiệp. Các biện pháp phức tạp của WM yêu cầu nhiều quá trình phụ, khiến cho việc cô lập các đóng góp cụ thể của các hệ thống phụ được giả định độc lập trở nên khó khăn. Nghiên cứu hiện tại được thiết kế để xác định xem các chỉ số neurophysiological của các quá trình phụ được đề xuất của WM có dự đoán được hiệu suất WM hay không. Chúng tôi đã tuyển dụng 200 cá nhân xác định bởi trạng thái tìm kiếm sự chăm sóc và đo phản ứng thần kinh bằng cách sử dụng điện não đồ (EEG), trong khi các người tham gia thực hiện bốn nhiệm vụ WM. Chúng tôi đã trích xuất các đặc điểm EEG theo phổ và theo miền thời gian từ mỗi nhiệm vụ để định lượng từng quá trình phụ được giả định của WM:
