Tóm tắt

Trong hai thí nghiệm, các đối tượng đã ngâm một bàn tay và cẳng tay vào nước đá (thử nghiệm lạnh) trong 60 giây và đánh giá cường độ đau mỗi 5 giây. Bốn mươi đối tượng đã ngâm một cánh tay trong ba lần thí nghiệm ở Thí nghiệm 1, và 60 đối tượng ngâm một cánh tay trong hai lần thí nghiệm ở Thí nghiệm 2. Các hàm tuyến tính, hàm mũ, hoặc hàm hằng số tổng hợp phù hợp với dữ liệu gần như bằng nhau. Các số mũ của hàm mũ hai hằng số khác với các số của hàm hằng số tổng hợp. Sự khác biệt cá nhân trong các số mũ là đáng kể, nhưng các thao tác tâm lý khác nhau nhằm giảm đau đã không ảnh hưởng đến các số mũ này. Độ hữu ích của các hàm mũ để mô tả đau do thử nghiệm lạnh vẫn chưa được xác định.
