Developmental aspects of synaesthesia across the adult lifespan

In synaesthesia, stimuli such as sounds, words or letters trigger experiences of colors, shapes or tastes and the consistency of these experiences is a hallmark of this condition. In this study we investigate for the first time whether there are age-related changes in the consistency of synaesthetic experiences. We tested a sample of more than 400 grapheme-color synaesthetes who have color experiences when they see letters and/or digits with a well-established test of consistency. Our results showed a decline in the number of consistent grapheme-color associations across the adult lifespan. We also assessed age-related changes in the breadth of the color spectrum. The results showed that the appearance of primary colors (i.e., red, blue, and green) was mainly age-invariant. However, there was a decline in the occurrence of lurid colors while brown and achromatic tones occurred more often as concurrents in older age. These shifts in the color spectrum suggest that synaesthesia does not simply fade, but rather undergoes more comprehensive changes. We propose that these changes are the result of a combination of both age-related perceptual and memory processing shifts.

Intellectual Property and Traditional Cultural Expressions in a Digital Environment. Preface

In the face of increasing globalisation, there is a pressing need for innovative trans-disciplinary analyses of the value of traditional cultural expressions (TCE) that also suggest appropriate protection mechanisms for them. The book to which this preface belongs combines approaches from history, philosophy, anthropology, sociology and law, and charts previously untravelled paths for developing new policy tools and legal designs that go beyond conventional copyright models. It reflects also upon the specific features of the digital environment, which, despite enhancing the risks of misappropriation of traditional knowledge and creativity, may equally offer some opportunities for revitalising indigenous peoples' values and provide for the sustainability of TCE.

Differential aspects of memory self-evaluation in old and very old people

The aim of this paper was to examine age-related changes and gender differences in memory self-evaluation in old people and to examine the predictive power of objective memory performance and of personality variables (neuroticism and extraversion) on memory self-evaluation. In a cross-sectional study, 301 not institutionalized people aged 65± 94, 207 male and 94 female, were tested on three parameters. Subjective memory evaluation was operationalized with three one-item ratings: temporal comparison, social comparison, situation-speci® c memory self-evaluation just after performing a memory test. Objective memory assessment (free recall) used a computerized test. Personality assessment included the two main sub-scales `extraversion’ and `neuroticism’ from the Freiburger PersoÈ nlichkeits-Inventar.The results shaved that persons of all age groups have a realistic appraisal of their age-related memory decline.No gender effects were found for any of the three forms of memory self-evaluation. The relationship between objective memory performance, personality variables and memory self-evaluation however depends on age and gender. Our results show that objective memory performance is predictive for memory self-evaluation in men aged >75 years, whereas in men <75 neuroticism is the only signi® cant predictor.Men of the older cohort seem to have adapted to the age-related memory decline whereas the young old are still coping with the ongoing changes. In women of both age groups the objective memory performance is the only and strong predictor of memory self-evaluation. Our results suggest that gender-speci® c educational socialization might be the reason for these differences.

How do different aspects of self-regulation predict successful adaptation to school?

Self-regulation plays an important role in successful adaptation to preschool and school contexts as well as in later academic achievement. The current study relates different aspects of self-regulation such as temperamental effortful control and executive functions (updating, inhibition, and shifting) to different aspects of adaptation to school such as learning-related behavior, school grades, and performance in standardized achievement tests. The relationship between executive functions/effortful control and academic achievement has been established in previous studies; however, little is known about their unique contributions to different aspects of adaptation to school and the interplay of these factors in young school children. Results of a 1-year longitudinal study (N = 459) revealed that unique contributions of effortful control (parental report) to school grades were fully mediated by children’s learning-related behavior. On the other hand, the unique contributions of executive functions (performance on tasks) to school grades were only partially mediated by children’s learning-related behavior. Moreover, executive functions predicted performance in standardized achievement tests exclusively, with comparable predictive power for mathematical and reading/writing skills. Controlling for fluid intelligence did not change the pattern of prediction substantially, and fluid intelligence did not explain any variance above that of the two included aspects of self-regulation. Although effortful control and executive functions were not significantly related to each other, both aspects of self-regulation were shown to be important for fostering early learning and good classroom adjustment in children around transition to school.
