Using Your Head: Measuring Infants' Rational Imitation of Actions

Source: Laboratories of Judith Danovitch and Nicholaus Noles—University of Louisville
One of the main challenges of infancy is to learn how to achieve one’s goals in the world, whether they are to pick up a toy or to express desires to another person, and one of the most powerful tools in this learning process is imitation. However, imitation is not always as simple as copying other people’s actions; it is also necessary to realize that goals and intentions guide behavior. The...

Rational Emotive Behavior Therapy

Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...

Rational Dosage Regimen: Maintenance Dose and Loading Dose

5.4K
A rational dosage regimen considers a drug's pharmacokinetics, including its absorption, distribution, metabolism, and elimination from the body. By understanding these factors, the appropriate dosage can be determined, and the dosing schedule can be designed to achieve and maintain the desired therapeutic effect while minimizing adverse effects.
In most cases, drugs are administered repetitively or infused continuously to maintain a steady-state concentration in the body. At a steady...

Attitudes

32.7K
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;...

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.

Area of Science:

  • Moral philosophy
  • Cognitive science
  • Psychology of reasoning

Background:

  • Moral judgments are often viewed optimistically regarding their origins and outcomes.
  • Reasoning is considered a primary source for the content and consequences of moral judgments.

Purpose of the Study:

  • To evaluate the optimism surrounding the source, content, and consequences of moral judgments.
  • To investigate the relationship between reasoning ability and the attainment of moral knowledge.

Main Methods:

  • Analysis of existing evidence on reasoning capabilities.
  • Theoretical examination of the link between reasoning and moral knowledge acquisition.

Main Results:

  • Optimism about the source of moral judgments (reasoning) is partially justified.
  • Pessimism is warranted regarding the content and consequences of moral judgments due to widespread poor reasoning.
  • Evidence indicates that most people are not good reasoners, limiting their capacity for moral knowledge.

Conclusions:

  • While good reasoners can achieve moral knowledge, the majority of the population may not possess this capability.
  • The prevalence of suboptimal reasoning skills has significant implications for the content and consequences of societal moral judgments.
