Naturalistic Observations

16.7K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Ecological Niches

25.3K
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Criteria for Causality: Bradford Hill Criteria - II01:28

Criteria for Causality: Bradford Hill Criteria - II

920
The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts:

Ecological Disturbance02:26

Ecological Disturbance

20.0K
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Reliability and Validity01:29

Reliability and Validity

13.4K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

The Bradford Hill criteria are a group of principles that provide a framework to determine a causal relationship between a specific factor and a disease. There are nine criteria that are pivotal in assessing causality in epidemiological studies. Here's a closer look at Strength, Consistency, Specificity, and Temporality criteria with definitions and examples:

Summary
This summary is machine-generated.

Ecological validity, a concept from Egon Brunswik and Martin Orne, refers to how well experimental findings generalize to the real world. The validity of perceptual cues directly impacts the ecological validity of the entire experiment.

Area of Science:

  • Psychology
  • Cognitive Science
  • Research Methodology

Background:

  • The concept of ecological validity is crucial for understanding the applicability of research findings.
  • Two distinct but related definitions of ecological validity exist, originating from different researchers.

Purpose of the Study:

  • To clarify the dual definitions of ecological validity.
  • To establish the relationship between cue validity and experimental ecological validity.

Main Methods:

  • Review of the conceptual origins of ecological validity.
  • Analysis of the relationship between perceptual cue validity and generalization of findings.

Main Results:

  • Egon Brunswik defined ecological validity as the correlation between perceptual cues and stimulus properties.
  • Martin Orne defined ecological validity as the generalizability of experimental results to real-world settings.

Conclusions:

  • Both definitions of ecological validity are valid and interconnected.
  • The ecological validity of perceptual cues is a prerequisite for the ecological validity of an experiment.
