What did the Seattle Longitudinal Study Find?

What did the Seattle Longitudinal Study Find?

The findings suggest that during young old age, the slopes of decline for several of the primary mental abilities have significantly flattened. This is the case for Verbal Meaning, Inductive Reasoning, Spatial Orientation, and Psychomotor Speed.

What is the Seattle Longitudinal Study quizlet?

The Seattle Longitudinal Study measured the output of all five primary mental abilities: verbal meaning, spatial orientation, inductive reasoning, number ability, and word fluency – all declined beginning at about age 60.

What did the Seattle Longitudinal Study discover regarding people’s intelligence as they age?

the rate and magnitude changes in intelligence seen in those entering old age showed greater decline in the 1st 3 cycles (till 1970); at the same time, younger members are scoring lower on tests at the same age. a decline in psychometric abilities is not reliably observed before 60, but is reliably observed by 74.

What is the most common change in sleep patterns of adults during middle age?

What is the most common change in sleep patterns of adults during middle age? They spend less time in deep sleep.

What do longitudinal studies on intelligence in adulthood report?

The Seattle Longitudinal Study measured the output of all five primary mental abilities: verbal meaning, spatial orientation, inductive reasoning, number ability, and word fluency – all declined beginning at about age 60.

What did she discover about longitudinal and cross sectional assessments of intellectual abilities?

the rate and magnitude changes in intelligence seen in those entering old age showed greater decline in the 1st 3 cycles (till 1970); at the same time, younger members are scoring lower on tests at the same age. a decline in psychometric abilities is not reliably observed before 60, but is reliably observed by 74.

What is longitudinal study quizlet?

The findings suggest that during young old age, the slopes of decline for several of the primary mental abilities have significantly flattened. This is the case for Verbal Meaning, Inductive Reasoning, Spatial Orientation, and Psychomotor Speed.

What is the purpose of longitudinal studies quizlet?

A longitudinal study follows the same sample over time and makes repeated observations. A longitudinal survey, for example, surveys the same group of people at regular intervals, enabling researchers to track changes over time.

What did the Seattle Longitudinal Study Find about aging?

The findings suggest that during young old age, the slopes of decline for several of the primary mental abilities have significantly flattened. This is the case for Verbal Meaning, Inductive Reasoning, Spatial Orientation, and Psychomotor Speed. (Schaie, 2004).

What did the Seattle Longitudinal Study test?

The SLS is unique as a cohort-sequential longitudinal study, examining cognitive and psychosocial change in multiple birth cohorts over the same chronological age span.

What do longitudinal studies of intelligence reveal?

Longitudinal research usually shows that intelligent in most abilities increase through out early and middle adulthood. Many adults show intellectual improvement over most of adulthood, with not decline, even by age 60.

Which sleep change occurs with age?

Age-related changes in sleep include advanced sleep timing, shortened nocturnal sleep duration, increased frequency of daytime naps, increased number of nocturnal awakenings and time spent awake during the night, and decreased slow wave sleep.

What is the most common bedtime for adults?

Americans spend an average of 7 hours and 18 minutes in bed each night. They go to bed at 11:39 p.m., wake up at 7:09 a.m., spend 23.95 minutes snoring, have an average sleep quality of 74.2 percent, and rate their wake-up mood at 57 on a scale of 100.

Why do sleep patterns change with age?

As you age your body produces lower levels of growth hormone, so you’ll likely experience a decrease in slow wave or deep sleep (an especially refreshing part of the sleep cycle). When this happens you produce less melatonin, meaning you’ll often experience more fragmented sleep and wake up more often during the night.

Which age group gets the most sleep in a typical 24 hour cycle?

What is a longitudinal study and why are they important to developmental psychology?

Longitudinal research designs are used to examine behavior in the same infants and children over time. For example, when considering our example of hide-and-seek behaviors in preschoolers, a researcher might conduct a longitudinal study to examine whether 2-year-olds develop into better hiders over time.

What is one advantage of a longitudinal study design when conducting research with older adults?

The findings suggest that during young old age, the slopes of decline for several of the primary mental abilities have significantly flattened. This is the case for Verbal Meaning, Inductive Reasoning, Spatial Orientation, and Psychomotor Speed. (Schaie, 2004).

What is the value of longitudinal studies for human development?

The benefit of a longitudinal study is that researchers are able to detect developments or changes in the characteristics of the target population at both the group and the individual level. The key here is that longitudinal studies extend beyond a single moment in time.

What did the Seattle Longitudinal Study discover regarding people intelligence as they age?

Changes in Rate of Aging The findings suggest that during young old age, the slopes of decline for several of the primary mental abilities have significantly flattened. This is the case for Verbal Meaning, Inductive Reasoning, Spatial Orientation, and Psychomotor Speed. (Schaie, 2004).

Who came up with longitudinal study?

The oldest reported longitudinal growth record is attributed to Count Philibert Gueneau de Montbeillard, who measured his son every 6 months (from 1759 to 1777) and published it in Buffon’s Histoire Naturelle (Tanner 1989).

What do cross-sectional studies show about intelligence?

F. Cross-sectional research shows a decline in intellectual ability. 4. Longitudinal research usually shows that intelligent in most abilities increase through out early and middle adulthood.

Which statement is a finding of the Seattle Longitudinal Study?

Age-graded factors: Schaie’s Seattle Longitudinal Study found that Thurstone’s mental abilities increased until the early 40s and stabilized until the 50s or 60s. After age 60, losses emerge on all scales, but measures of speed related fluid skills begin to decline by the early 30s.

What is longitudinal study?

A longitudinal study, like a cross-sectional one, is observational. So, once again, researchers do not interfere with their subjects. However, in a longitudinal study, researchers conduct several observations of the same subjects over a period of time, sometimes lasting many years

What is longitudinal research quizlet?

longitudinal research. A longitudinal survey is a correlational research study that involves repeated observations of the same variables over long periods of time often many decades. It is a type of observational study.

What is a longitudinal design quizlet?

Longitudinal Study Design. –Two or more observations of a certain characteristic within the same group. -usually an OBSERVATIONAL study design.
