A Study on the Recognition and Memory of Shapes for the Elderly

This research is mainly aimed at exploring the recognition and memory ability of basic geometric shapes in the elderly, in order to understand the status of recognition and memory ability of shapes of different complexity in the elderly. It is mainly carried out through the experimental method. The experimental method is carried out with 12 shape test samples, and the accuracy of shape recognition and different time differences are discussed. The subjects were divided into 10 elderly people in the experimental group and 10 college students over the age of 20 in the control group. The results show that there is a gap in the accuracy of shape recognition among the elderly. The more complex the shape, the lower the recognition ability. In addition, both groups of subjects made errors in recognizing the obliquely angled figures. The time difference between 5 s and 30 s between shape F (original hexagon) and shape I (hexagon with rounded corners) is significantly different, and shape I obtains the lowest recognition accuracy rate at a 5-s interval for the elderly. The experimental results also show that the front and back positions of the shape images in the sequence have an impact on the memory ability.
