Therapeutic Communication01:30

Therapeutic Communication

4.8K
Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

Attitudes

28.8K
Attitude is our evaluation of a person, an idea, or an object. We have attitudes for many things ranging from products that we might pick up in the supermarket to people around the world to political policies. Typically, attitudes are favorable or unfavorable: positive or negative (Eagly & Chaiken, 1993). And, they have three components: an affective component (feelings), a behavioral component (the effect of the attitude on behavior), and a cognitive component (belief and knowledge;...

Framing Effects03:26

Framing Effects

7.5K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Social Loafing01:37

Social Loafing

35.4K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Bystander Effect02:09

Bystander Effect

9.6K
The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Self-Evaluation: Self-Enhancement and Self-Verification03:00

Self-Evaluation: Self-Enhancement and Self-Verification

5.3K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Summary

Social incentives boost cooperative effort more when linked to initial choices than to actual exertion. This finding suggests declarations of cooperation tied to social rewards can enhance group contributions.

Area of Science:

  • Behavioral Economics
  • Social Psychology
  • Decision Science

Background:

  • Financial and social incentives are common strategies to promote cooperation.
  • Incentives may be less effective during effort execution compared to effort choice.
  • Cooperative effort requires understanding how incentives influence behavior.

Purpose of the Study:

  • To empirically investigate the impact of social incentives on cooperative effort.
  • To explore whether social incentives affect cooperative choices or effort execution differently.
  • To inform strategies for enhancing cooperation through targeted incentive design.

Main Methods:

  • A modified public goods game task was used, requiring effort contributions.
  • Social incentives were incorporated and linked either to cooperative choices or effortful actions.
  • The study compared the effects of these two incentive structures on cooperative behavior.

Main Results:

  • Social incentives demonstrated a stronger effect on cooperative effort when tied to choices rather than exerted effort.
  • Findings align with effort-based decision-making models.
  • Linking incentives to a priori declarations of cooperation proved more effective.

Conclusions:

  • Social incentives are more impactful on cooperative effort when associated with the decision to cooperate.
  • Eliciting upfront commitments to cooperation, coupled with social incentives, can foster greater collective effort.
  • This approach offers a promising avenue for improving group outcomes through behavioral interventions.
