Summary
Researchers developed the Self-Report Altruism Scale Distinguished by the Recipient (SRAS-DR) to better understand evolutionary altruism. This new scale reliably measures altruistic behaviors towards different recipients, proving valuable for future evolutionary studies.
Area of Science:
- Psychology
- Evolutionary Biology
- Social Sciences
Context:
- Altruistic behavior is crucial in evolutionary studies.
- Existing scales lack recipient distinction, limiting evolutionary research.
- Understanding the actor-recipient relationship in altruism is key.
Purpose:
- To develop and validate a new self-report altruism scale distinguishing recipients.
- To create the Self-Report Altruism Scale Distinguished by the Recipient (SRAS-DR).
- To provide a tool for evolutionary studies on human altruism.
Summary:
- The SRAS-DR was developed in two studies using Japanese undergraduates.
- Study 1 identified altruistic behaviors towards family, friends, and strangers, leading to 21 scale items.
- Study 2 confirmed the scale's reliability and validity through correlations with other measures and behavioral indicators.
Impact:
- The SRAS-DR demonstrates high reliability and validity.
- This scale can be effectively utilized in evolutionary studies of human altruism.
- Provides a nuanced measure of altruism based on recipient categories.

01:22Self-Report Tests of Personality
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.
01:55Egoism and Altruism
Voluntary behavior with the intent to help other people is called prosocial behavior. Why do people help other people? Is personal benefit such as feeling good about oneself the only reason people help one another?
01:03Altruism
Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.
02:16Surveys
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
01:29Self-Serving Bias
Self-serving bias is a cognitive phenomenon in which individuals attribute positive outcomes to internal factors such as their abilities, intelligence, or effort while attributing negative outcomes to external circumstances. This cognitive distortion helps maintain self-esteem but can also impede objective self-assessment.Theoretical Explanations of Self-Serving BiasTwo primary theories explain the self-serving bias: the cognitive explanation and the motivational explanation.The cognitive...
02:45Self-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.
