This system had parameters that described capacities and decay rates

for memories, cycle times for processor subsystems, and other processes.

The parameters were estimated from experimental studies. However, most

of the experiments used young adults (usually college undergraduates) as

the sampling population, so such parameter estimates are not adequate to

describe older adults’ performance.

A few researchers have since attempted to derive parameters for

older adults, and some recent estimates for the age 60+ population from

Jastrzembski and Charness (2007) are given in Table 16.1. Numbers in

parentheses represent upper and lower bounds for the parameters, similar

to a confidence interval for a statistical parameter. These values can be used

to try to simulate middle-aged and old-old populations. Corresponding to

the rule of thumb offered in Chapter 2, most of the estimates for processor

cycle times for older adults are between 1.5 and 2 times as long as those

for younger adults.

GOMS modeling is meant to be applied to routine task performance,

that is, performance that is well practiced. It would not be applicable

to novice performance that involves problem-solving activity. As such,

GOMS models would be expected to generalize to tasks after people

have acquired reasonable proficiency. Such models should provide good

estimates of stable performance such as that found in job settings. As

usual, it is worth keeping in mind that the older adult population is

highly variable, and so any particular model can be expected to provide

ordinal information about design decisions, that is, whether design A is superior to design B, and the actual time (or accuracy) advantage for a

given design may vary depending on the specific older adult population.

Below we provide a fairly elementary example of estimating the time to

enter data on a computer.

    該系統有這樣的描述能力和衰減率參數對於存儲器,循環時間為處理器子系統,以及其他處理。參數進行了實驗研究的估計。然而,大多數使用年輕人(一般大學本科生)實驗作為採樣人口,所以這樣的參數的估計是不足以形容老年人的表現。

    一些研究者已經試圖以來派生參數老年人,以及一些最新的估計為年齡60歲以上的人口從Jastrzembski和Charness(2007)列於表16.1。在數字括號表示為參數的上限和下限,類似為一個統計參數的置信區間。這些值可用於要盡量模擬中年和高齡人群。對應經驗法則第2章提供的,大部分估計處理器循環時間為老年人是1.5至2倍,只要這些為年輕的成年人。GOMS建模是指將應用於日常任務的性能,即性能是良好實施。它並不適用新手的表現,涉及到解決問題的活動。因此,GOMS模型預計將推廣到人之後的任務已獲得合理的水平。這種模式應提供良好的性能穩定的估計,如在作業設置找到。如:

    平時,它是值得牢記老成人人口高度可變的,並且因此任何特定模型可以預期提供

    關於設計決策序的信息,即是否設計A為優良,設計B和實際時間(或精度)的優點為一給定的設計可以根據特定的年齡較大的成人群體而變化。下面,我們提供估計時間的一個相當初等示例輸入的計算機上的數據。
