组织行为学：智力能力和体力能力

组织行为学：Individual’s overall abilities

An individual’s overall abilities are essentially made up of two sets of factors: intellectual and physical abilities.

1. Intellectual abilities

Intellectual abilities are those required to do mental activities.

1.1IQ tests

IQ tests are designed to ascertain one’s general intellectual abilities. So, too, are popular college admission tests like the SAT and ACT and graduate admission tests in business (GMAT), law (LSAT), and medicine (MCAT)

1.2Dimensions of intellectual abilities

The seven most frequently cited dimensions making up intellectual abilities are number aptitude, verbal comprehension, perceptual speed, inductive reasoning, deductive reasoning, spatial visualization, and memory.

(1)Number aptitude

Ability to do speedy and accurate arithmetic__ Job example: accountant __

computing the sales tax on a set of items

(2)Verbal comprehension

Ability to understand what is read or heard and the relationship of words to each

other __ Job example: plant manager __following corporate policies

(3)Perceptual speed

Ability to identify visual similarities and differences quickly and accurately __ Job

example: fire investigator __identifying clues to support a charge of arson

(4)Inductive reasoning

Ability to identify a logical sequence in a problem and then solve the problem __

Job example: market researcher: forecasting demand for a product in the next time period

(5)Deductive reasoning

Ability to use logic and assess the implications of an argument__ Job example: supervisor __choosing between two different suggestions offered by employees (6)Spatial visualization

Ability to imagine how an object would look if its position in space were changed__ Job example: interior decorator ___redecorating an office

(7)Memory

Ability to retain and recall past experiences __Job example: salesperson __remembering the names of customers

Jobs differ in the demands they place on incumbents to use their intellectual abilities. Generally speaking, the more information processing demands that exist in a job, the more general intelligence and verbal abilities will be necessary to perform the job successfully.

A high IQ is not a prerequisite for all jobs. In fact, for many jobs — where employee behavior is highly routine and there are little or no opportunities to exercise discretion —a high IQ may be unrelated to performance

The major dilemma faced by employers who use mental ability tests for selection, promotion, training, and similar personnel decisions is that they may have a negative impact on racial and ethnic groups. The evidence indicates that some minority groups score, on the average, as much as one standard deviation lower than whites on verbal, numerical, and spatial ability tests.

2. Physical abilities

Physical abilities are those required to do tasks demanding stamina,dexterity, strength, and similar skills. Contrary to与...相反what we were taught in grade school, we were not all created equal. 【stamina[ ???????]毅力, 耐力__dexterity[???????????]灵巧, 机敏

__contrary __】

Specific physical abilities gain importance for successfully doing less skilled and more standardized jobs.

Nine basic physical abilities

Research on the requirements needed in hundreds of jobs has identified nine basic abilities involved in the performance of physical tasks.

?Strength factors

(1)Dynamic strength

Ability to exert muscular force repeatedly or continuously over time

(2)Trunk strength

Ability to exert muscular strength using the trunk, particularly abdominal,

muscles

(3)Static strength

Ability to exert force against external objects

(4)Explosive strength

Ability to expend a maximum of energy in one or a series of explosive acts ?Flexibility factors

(5)Extent flexibility

Ability to move the trunk and back muscles as far as possible

(6)Dynamic flexibility

Ability to make rapid, repeated flexing movements

?Other factors

(7)Body coordination

Ability to coordinate the simultaneous actions of different parts of the body

(8)Balance

Ability to maintain equilibrium despite forces pulling off balance

(9)Stamina

Ability to continue maximum effort requiring prolonged effort over time Source: reprinted from the June 1979 issue of Personnel Administrator, copyright 1979, the American Society for Personnel Administration; 606 North Washington Street, Alexandria, Virginia 22314, pp. 82~92

Individuals differ in the extent to which they have each of these abilities. Not surprisingly,

there is also little relationship between them: a high score on one is no assurance of a high score on others.

High employee performance is likely to be achieved when management has ascertained the extent to which a job requires each of the nine abilities and then ensures that employees in that job have those abilities.

这样看起来，反而是朝生暮死的蝴蝶为可羡了。它们在短短的一春里尽情地酣足地在花间飞舞，一旦春尽花残，便爽爽快快地殉着春光化去，好像它们一生只是为了酣舞与享乐而来的，倒要痛快些。像人类呢，青春如流水一般的长逝之后，数十载风雨绵绵的灰色生活又将怎样度过？
