Causes of Similarity-Dissimilarity Effect

230
The similarity-dissimilarity effect, a fundamental concept in social psychology, explains how interpersonal similarities and differences influence attraction and social interactions. This effect is supported by three key psychological perspectives: balance theory, social comparison theory, and consensual validation.Balance Theory and Cognitive ConsistencyBalance theory, developed by Fritz Heider, posits that individuals seek cognitive consistency in their relationships. When two people share...

Social Loafing01:37

Social Loafing

38.9K
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,...

Regression Toward the Mean

6.8K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Spare Receptors

4.4K
Some receptors remain unoccupied even when an agonist produces a maximal response. Such empty ones are called spare receptors. In presence of spare receptors the maximum effect of an agonist drug is achieved with fewer than 100% of the receptors being occupied. To determine the presence of spare receptors, scientists often compare the concentration of the drug needed to produce 50% of the maximum effect (EC50) with the concentration of the drug needed to occupy 50% of the receptors (Kd). If the...

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Groupthink

48.9K
When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...

Summary

Canadian pharmaceutical spending is rising rapidly, outpacing other healthcare costs. New strategies like adjusted co-payments and physician budgets are needed to ensure cost-effective drug prescribing and utilization.

Area of Science:

  • Health Economics
  • Pharmaceutical Policy
  • Healthcare Management

Background:

  • Pharmaceutical expenditures in Canada are growing at twice the rate of other healthcare spending.
  • Current methods for controlling pharmaceutical costs are proving ineffective.
  • Existing policy recommendations (evidence, dissemination, regulation, dialogue) are insufficient for cost-effective prescribing.

Discussion:

  • Proposes three complementary strategies to enhance current pharmaceutical cost-containment policies.
  • Suggests restructuring consumer co-payments based on therapeutic necessity.
  • Recommends physician budgets for potentially overused pharmaceuticals and price-volume contracts with industry.

Key Insights:

  • Consumer co-payment adjustments can improve value perception for pharmaceuticals.

Related Experiment Videos

  • Physician budgets and price-volume contracts incentivize cost-effective prescribing and marketing.
  • Evidence and dissemination alone do not guarantee cost-effective pharmaceutical use.
  • Outlook:

    • These strategies aim to align patient, physician, and industry incentives with cost-effective drug utilization.
    • Implementation could lead to more sustainable pharmaceutical spending within the Canadian healthcare system.
    • Further research into the economic impact and practical application of these novel strategies is warranted.
