Prof. Morrow’s research focuses on learning, cognition, and communication in complex task domains such as health care and aviation, with a focus on aging. Recent projects have investigated the impact of health literacy (and cognition more broadly) on older adults’ comprehension of information needed to self-manage chronic illness. Focusing on older adults with hypertension, Prof. Morrow’s group has found that lower health literacy reflects lower levels of processing capacity (such as working memory) and knowledge (related to language and health). Processing capacity limits impair specific processes involved in understanding information needed to self-manage hypertension, such as recognizing longer and uncommon words and integrating concepts into a representation of the message. However, high levels of knowledge can offset these processing capacity limits to improve memory for self-care information. In a recent study, they redesigned self-care information found on commonly used websites in order to reduce comprehension demands on processing capacity and support the use of knowledge. Older adults better remembered the redesigned information compared to the original web-based information.
