    Facial recognition and visual processing as we age:Using the Thatcher illusion with famous and non-famous faces

    This paper reports a study examining preferred visual processes in recognition of facial features in older vs younger age groups, using Thatcherised images of famous and non-famous people in the one study. The aims were to determine whether decline in visual system processing occurs increasingly as we grow older, and whether there is less decline in recognition of famous (or familiar) faces. Three groups (younger, middle-old and older) made up the sample of 73 people (aged 19-82 years). Visual decline in face recognition across the age groups was assessed based on the Thatcher illusion—using four famous and four non-famous faces either with normal features or with distorted features. The faces were presented one at a time on computer screen, and participants were asked to judge whether the face was distorted (eyes and/or mouth not aligned in relation to the face); in addition, time taken to decision (latency) was also measured. Decline was found in visual processing such that older individuals gave limited attention to facial details (processing faces holistically, with detail errors) and they took longer to decide. Whether the faces were famous or not did not have significant effects on the decisions and there was no interaction with age, though famous faces were given longer attention. Our visual system processes decline as we age in that we give less attention to details and more to holistic processing and so make more errors in recognition. Implications for treatment or amelioration of the effects are discussed.</jats:p

    Emotion recognition and verbal and non-verbal memory changes among older adults: Is decline generalised or modular?

    Declines in cognitive abilities among ageing adults are observed phenomena. But are these declines ‘across the board’ or are they modular? The answer affects theory and practice, including potential treatments that may reduce the declines. Deficits in emotion recognition may provide a window into what is occurring in the ageing brain. We investigated whether changes in recognition of emotion could be attributed to a decline in memory processes. Sixty-two participants recruited from South-Eastern Queensland divided into young (19-49), middle old (49-64) and old (65 and above) cohorts performed computer administered tasks assessing emotion recognition, verbal and non-verbal memory. Older adults evidenced decline in recognition of anger, surprised and fearful faces. In addition, age related decline was evident in verbal memory performance. However, there was no corresponding decline in non-verbal memory performance. The dissociation of non-verbal memory performance from emotion recognition performance provides support for a modular decline model of age-related decline. The detection of decline in both verbal memory performance and emotion recognition suggests a common underlying process may be associated with both. Performance on the emotion recognition task may be verbally mediated. This study provides valuable insight into the ageing process and suggests decline may occur asynchronously- that is, is modular

    Furniture Industry Panel

    Panelists from three major furniture designers, Haworth, Herman Miller and Steelcase, all located close to the Grand Valley campus, will share their stories about using furniture to revitalize and repurpose spaces for both large and small spaces. They’ll talk about matching function to form, designing for maximum flexibility, catering to the needs of different age groups, and, along the way, address what librarians need to bring to the table when they work with furniture designers
