Secondary Motives: Power Motivation and Achievement Motivation

107
Power motivation and achievement motivation are two essential social motives identified by psychologist David McClelland. These motives influence behavior in various personal and professional contexts, shaping how individuals interact with others and pursue their goals.
Power motivation is characterized by the desire to influence, control, or have an impact on others. It is shaped by an individual's experiences, social environment, and cultural context. People with high power motivation are...

Factors Affecting Perception01:25

Factors Affecting Perception

1.4K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

The concept of work involves force and displacement; meanwhile, the work-energy theorem relates the net work done on a body to the difference in its kinetic energy, calculated between two points on its trajectory. While none of these quantities or relations involves time explicitly, we know that the time available to accomplish work is often just as important as the amount of work itself. For example, sprinters in a race may have achieved the same velocity at the finish, therefore,...

Complex Power

Power engineers have introduced the concept of complex power to determine the cumulative effect of parallel loads. This idea plays a crucial role in power analysis because it encompasses all the details related to the power consumed by a specific load.
Complex power is defined as the multiplication of the voltage and the complex conjugate of the current. The magnitude of this power, known as apparent power, is measured in volt-amperes (VA). Notably, the angle of the complex power equates to the...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

49.6K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Self-Report Tests of Personality01:22

Self-Report Tests of Personality

293
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Summary
This summary is machine-generated.

This study introduces a new scale to measure personal power and social power distinctly. Findings show these power types influence behaviors like advice-seeking and reactions to service failures differently.

Area of Science:

  • Psychology
  • Social Psychology
  • Organizational Behavior

Background:

  • Power is crucial in social interactions, influencing outcomes and autonomy.
  • Existing measures often conflate personal and social power, limiting nuanced understanding.
  • Differentiating power facets is essential for accurate behavioral prediction.

Purpose of the Study:

  • Develop and validate a robust two-factor scale for perceived power.
  • Distinguish between personal power (autonomy) and social power (influence over others).
  • Investigate the unique behavioral consequences of each power dimension.

Main Methods:

  • Validated a two-factor scale across twelve studies (N=2,878) using exploratory and confirmatory factor analyses.
  • Assessed scale reliability and validity.
  • Employed experimental manipulations and correlational designs to test differential predictions.

Main Results:

  • The new scale reliably and validly differentiates personal and social power.
  • Personal power was linked to increased proactive advice-seeking.
  • Social power was associated with reduced advice-seeking and amplified negative reactions to service failures.

Conclusions:

  • The validated scale offers a precise tool for measuring distinct power dimensions.
  • Personal and social power have unique, divergent effects on behavior.
  • This research advances the understanding of power dynamics in social and organizational contexts.
