Key Terms to Review (18)
Causal inference: Causal inference is the process of determining whether a change in one variable directly leads to a change in another variable. This concept is crucial for understanding relationships between variables and establishing cause-and-effect connections, especially in research settings. It relies on various methodologies to eliminate alternative explanations and help researchers draw valid conclusions about the effects of interventions or treatments.
Complexity: Complexity refers to the intricate and multifaceted nature of systems, concepts, or phenomena that consist of numerous interconnected elements. In the context of post-positivism, complexity highlights the limitations of reductionist approaches, emphasizing that understanding reality often requires considering the interplay of various factors and their relationships rather than isolating individual components.
Constructivist Critique: Constructivist critique refers to the analytical approach that challenges the assumptions and limitations of traditional positivist methodologies in research. This critique emphasizes that knowledge is constructed through social interactions and cultural contexts, rather than being an objective reflection of reality. It questions the validity of universal truths and highlights the importance of subjective experiences in understanding human behavior.
Contextuality: Contextuality refers to the idea that the meaning and interpretation of information, events, or phenomena are deeply influenced by the surrounding context in which they occur. This concept is crucial in understanding that knowledge is not absolute and can vary based on different factors such as culture, situation, or perspective, emphasizing the importance of recognizing these influences when conducting research.
Critical Realism: Critical realism is a philosophical approach that combines a realist ontology with a constructivist epistemology, emphasizing the importance of understanding the underlying structures that shape social phenomena while acknowledging that our knowledge of these structures is always mediated by social contexts and human perspectives. This perspective posits that reality exists independently of our perceptions, but our understanding of it is influenced by our experiences and interpretations, creating a balance between objective truths and subjective interpretations.
Critique of Certainty: The critique of certainty challenges the notion that knowledge can be absolutely known or that research findings are universally applicable. This perspective emphasizes the inherent uncertainty and complexity of social phenomena, suggesting that knowledge is shaped by context, perspectives, and interpretations rather than being fixed and objective. By questioning the foundations of certainty, this critique encourages a more nuanced understanding of truth in research and its implications for communication.
Empirical Observation: Empirical observation refers to the process of gathering data through direct experience or experimentation, focusing on observable phenomena. This approach emphasizes the importance of evidence that can be seen, measured, and tested, making it foundational in various research methodologies. By relying on empirical evidence, researchers can formulate hypotheses and draw conclusions based on real-world data rather than assumptions or theoretical constructs.
Falsifiability: Falsifiability is the principle that for a hypothesis or theory to be considered scientific, it must be testable and capable of being proven false. This idea emphasizes that if a statement cannot be tested or potentially disproven, it lacks empirical validity. The concept is essential in distinguishing between scientific claims and those that are unscientific, connecting closely with methods of inquiry and reasoning used in research.
Hypothesis Testing: Hypothesis testing is a statistical method used to determine whether there is enough evidence to reject a null hypothesis in favor of an alternative hypothesis. It involves collecting data, analyzing it, and making a decision about the validity of the hypothesis based on the results. This process is crucial in research as it helps researchers draw conclusions and make inferences about a population based on sample data.
Karl Popper: Karl Popper was a 20th-century philosopher known for his contributions to the philosophy of science, particularly his ideas on falsifiability as a criterion for scientific theories. His work challenged the traditional view of scientific inquiry, emphasizing that knowledge grows through conjectures and refutations rather than through verification. This perspective connects with post-positivism, where the understanding of knowledge is seen as provisional and open to revision, as well as with discussions on ontology and epistemology regarding the nature of reality and our understanding of it. Additionally, Popper's emphasis on deductive reasoning over inductive reasoning highlighted a fundamental shift in how scientific theories are formulated and tested.
Methodological pluralism: Methodological pluralism refers to the practice of using multiple methods or approaches to research a single issue or phenomenon. This approach acknowledges that no single method can capture the full complexity of social phenomena, allowing researchers to draw from both qualitative and quantitative techniques to enrich their findings. By integrating diverse perspectives, methodological pluralism enhances the depth and validity of research outcomes, making it particularly relevant in various fields, including social sciences and communication research.
Mixed methods: Mixed methods is a research approach that combines both qualitative and quantitative techniques to provide a more comprehensive understanding of a research problem. By integrating the strengths of both methods, researchers can enrich their findings, offering deeper insights and allowing for a more nuanced analysis. This approach is particularly useful in studies where complex phenomena require diverse data sources for a fuller perspective.
Multicausality: Multicausality refers to the concept that multiple factors contribute to an outcome or phenomenon, rather than a single cause. This idea challenges simplistic cause-and-effect reasoning by recognizing that various social, economic, and environmental influences can interact and lead to a complex web of causation, especially in social sciences.
Probabilistic Truth: Probabilistic truth refers to the idea that knowledge and truths can be understood in terms of probabilities rather than absolute certainties. This concept aligns with post-positivism, which acknowledges that human understanding of reality is inherently imperfect and influenced by various factors, such as social context and personal biases. By embracing probabilistic truth, researchers can better navigate the complexities of human behavior and communication, recognizing that findings are often subject to change based on new evidence or perspectives.
Quantitative analysis: Quantitative analysis is a research method that focuses on quantifying relationships, behaviors, or phenomena by collecting numerical data and employing statistical techniques. This approach allows researchers to identify patterns, test hypotheses, and make generalizations about populations based on sample data. By emphasizing measurable and objective information, quantitative analysis is particularly useful in drawing conclusions that can be generalized across larger groups.
Scientific Realism: Scientific realism is a philosophical viewpoint asserting that the world described by science is real and exists independently of our perceptions or beliefs. This perspective emphasizes that scientific theories provide a true or approximately true description of the nature of the world, and it maintains that entities posited by scientific theories, such as electrons or black holes, exist even if they are not directly observable.
Theory-ladenness: Theory-ladenness refers to the idea that our observations and interpretations of the world are influenced by the theoretical frameworks and prior knowledge we hold. This concept emphasizes that what we see and how we understand phenomena are not purely objective but are shaped by the theories and beliefs we bring to the observation process.
Thomas Kuhn: Thomas Kuhn was an influential philosopher of science best known for his concept of paradigm shifts, which describes how scientific progress occurs through revolutionary changes rather than gradual accumulation. His ideas challenge traditional views of scientific development, suggesting that science is not a straightforward process but rather involves periods of normal science followed by revolutionary shifts that redefine existing frameworks.
