2019-2-27Processing speed is the speed cognitive processes and motor responses are performed This declines with age and lots of cognitive processes are affected due to this For example Salthouse (1991) explored age-related decline in cognitive ability by testing 672 people between 20 and 84 years of age
Age differences in cognitive performance in later life: Relationships to self-reported Publication: Journal of Gerontology Authors: Hultsch DF Hammer M and Small BJ Publication year pages: 1993 48 1?11 Sample Size: 484 Results Conclusions and Implications: individual differences in self-reported health and activity predicted performance on multiple cognitive measures
In healthy individuals performance on processing-speed tasks declines as a function of age with measurable differences appearing as early as 30 years old (eg refs 12 13) Thus as famously noted by Kraeplin 14 the pattern of cognitive deficits associated with psychosis appears to mirror the pattern of decline seen in normal aging
Age differences in memory were found when the instructions emphasized memory but no age differences were observed in the condition that instead emphasized learning T A Salthouse "The Processing-Speed Theory of Adult Age Differences in Cognition " Psychological Review 103 no 3 (1996): 403–428
2017-5-11the evidence relevant to the processing-speed theory of cogni-tive aging phenomena The fundamental assumption in the the-ory is that a major factor contributing to age-related differences in memory and other aspects of cognitive functioning is a re-duction with increased age in the speed with which many cog-nitive operations can be executed
2016-9-28Timothy Salthouse (1996 2000 Kail Salthouse 1994): processing speed theory of adult age differences in cognition (fluid intelligence) much experimental date supports this position although there remains questions as to whether cognitive speed can account for all individual differences

Abstract A theory is proposed to account for some of the age-related differences reported in measures of Type A or fluid cognition The central hypothesis in the theory is that increased age in adulthood is associated with a decrease in the speed with which many processing operations can be executed and that this reduction in speed leads to impairments in cognitive functioning because of what

Human white matter integrity has been related to information processing speed but it is unknown whether impaired integrity results from localized processes or is a general property shared across white matter tracts Based on diffusion MRI scans of 132 healthy individuals with a narrow age range around 72 years the integrity of eight major white matter tracts was quantified using
Several explanations have been offered for this decline in memory functioning one is the processing speed theory of cognitive aging by Tim Salthouse Drawing on the findings of general slowing of cognitive processes as people grow older Salthouse argues that slower processing causes working-memory contents to decay thus reducing effective
Information processing theories explain how people work with or perform mental operations on information they have received These operations include all mental activities that involve noticing taking in manipulating storing combining or retrieving information This approach to human development emphasizes the fundamental mental processes involved in attention perception memory
2019-12-10Age differences for remembering and knowing were minimal in the faster 2-s encoding condition However in the longer 5-s encoding condition younger persons produced significantly more remember responses and older adults a greater number of know responses Salthouse TA The processing-speed theory of adult age differences in cognition
The relationship between processing speed and emotional difficulties is likely somewhat bi-directional and can become a vicious cycle for many children Thus children with slow processing speed are at risk for lower self-esteem depression and anxiety—and if these emotional difficulties arise they slow down children even further

This study involving a total of 161 adults between 20 and 79 years of age investigated age-related differences of cognitive processing in mental subtra ction Aggregated and individual data analyses were conducted to evaluate the re lative importance of working memory and sensorimotor speed in adult age differen ces in mental subtraction

Indeed Salthouse' Processing Speed Theory of Adult Age Differences in Cognition has become influential across the aging literature in providing an underlying basis for the decline observed in other complex cognitive abilities (i e Bashore et al 1997 Zimprich and Martin 2002 Salthouse and Ferrer-Caja 2003 Lemke and Zimprich 2005

Speed of Processing Theory Birren (1974) first theorized that generalized slowing of abilities underlies the cognitive decline that often occurs with age Abundant evidence now exists that as a part of the normal aging process many individuals experience a decline in the speed with which they process information (Salthouse 1985 1990)

Processing resources are considered an important determinant of cognitive aging 16–18 34–36 Perceptual speed refers to the speed with which mental comparisons are made and working memory involves the ability to hold and manipulate information in short-term memory stores 15 17 18 34–36 Both are essential for information processing and
