Self-Discrepancy Theory02:45

Self-Discrepancy Theory

19.0K
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.

Persuasion Strategies

Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Models of Health Promotion and Illness Prevention I

2.9K
A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

Desirable Characteristics in Others

136
Various factors, including the type of relationship, gender, and duration of the relationship, influence the perception of desirable characteristics in others. While certain traits such as trustworthiness, cooperativeness, agreeableness, and extraversion are universally valued across all relationships, other characteristics are context-dependent and gain prominence based on specific relational dynamics.Universal and Context-Dependent TraitsTrustworthiness and cooperativeness are fundamental...

Surveys

17.1K
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.

Models of Health Promotion and Illness Prevention II

2.2K
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Summary
This summary is machine-generated.

Older adults show lower physical activity intentions and prefer shorter, slower sessions. Interventions should target intention-building and promote daily, moderate-paced activity for seniors.

Area of Science:

  • Gerontology
  • Public Health
  • Behavioral Science

Background:

  • Understanding physical activity intentions is crucial for promoting healthy aging.
  • Differences in physical activity preferences exist across adult age groups.

Purpose of the Study:

  • To compare physical activity intentions and preferred implementation intentions among younger, middle-aged, and older adults.
  • To identify age-specific strategies for enhancing physical activity in older populations.

Main Methods:

  • Cross-sectional telephone survey of 1217 Australian adults (2016).
  • Analysis using multiple and ordinal regression to compare age groups (younger <45, middle-aged 45-64, older 65+).

Main Results:

  • 60% of older adults lacked physical activity intentions, versus 25% of younger adults.
  • Older adults preferred shorter (≤30 min) daily activity sessions, often slower-paced.
  • Younger adults preferred faster-paced activities.

Conclusions:

  • Physical activity interventions for older adults must address low intention rates.
  • Public health campaigns should encourage daily, 30-minute, slow-paced activity for seniors.
  • Tailoring interventions to age-specific preferences is key for effectiveness.
