Information behavior of people in the fourth age: Implications for the conceptualization of information literacy

The information literacy (IL) needs of people in the fourth age, a stage of increasing dependence and disability, have not been considered in the research literature. Based on the premise that there are relationships between information seeking and IL, this article begins to bridge this gap by focusing on the information-seeking behavior of the group in an attempt to identify IL needs. It does this through a literature review, particularly drawing on two pieces of human information behavior research, one a new study focused specifically on the group in question. It also examines existing definitions of IL in order to gauge how relevant they appear to be. The reasons for studying this group include that all stages of a person's lifespan deserve to be studied and that the population size of this group increases dramatically in the developed world. Although information needs and sources used are fewer in the fourth age, they are still important to the people involved, thus making IL a relevant concept. The researchers draw implications for IL from the particularities of the information context where disability and frailty impede purposeful information seeking. The resulting emphasis on incidental information acquisition increases the role for social networks and communication, again with implications for IL. Information grounds, where people congregate for purposes other than information sharing, including artificially created ones, will also be important for information dissemination. The role of the Internet, including assistive technology for its use, is also relevant. The conclusion is that IL is crucial to the well-being of people in the fourth age but that existing definitions need to be adjusted to the specific informational context.     

Coincidence timing of a tennis stroke: effects of age, skill level, gender, stimulus velocity, and attention demand

Participants (N = 162, ages 10-15 years) performed a tennis stroke in a coincidence-timing task. Major results were: (a) performance improved mainly between the ages of 10-13 years; (b) skill differences were reflected by variable error (VE); (c) boys were lower than girls for VE and absolute error; (d) high stimulus velocity was related to low VE and late responding. Results concerning response organization favored explanations based on ecological perspectives rather than information processingperspectives. However, it is premature to disregard the potential role of programming. The view is supported that a continuous process of coupling perceptual and motor responses coordinates control of response timing. These cognitive processes appear to be: (a) refined with practice; (b) sensitive to differences in age, skill, and gender; and (c) adaptable to changes in environmental demands.
