24 Questions
What is the main advantage of the heliocentric model over the geocentric model in terms of explaining retrograde motion?
The heliocentric model provides a better fit to the data and explains retrograde motion via the notion that planets travel at different speeds along their orbits.
What is the primary purpose of models in scientific research, especially in complex systems?
Models help us predict and explain complex systems by abstracting key features and allowing us to instantiate, integrate, and compare different theories.
What type of models do psychologists typically work with, and what are some other examples of models?
Psychologists typically work with statistical models, such as regression models. Other examples of models include mechanical models (e.g., a physical model of the DNA double helix) and computational models (e.g., drift-diffusion model for decision making).
What is the main difference between a model and the system it represents?
A model represents its target system, but is not the system itself, similar to how a map represents its territory but is not the territory itself.
What is an example of a computational model used in decision making, and how can it be used in research?
The drift-diffusion model is a computational model of decision making. It can be used to study how people decide what is true or false, and to analyze response times in decision-making tasks.
What type of model represents the psychological processes that may have generated decision-making data?
Computational model, specifically an evidence accumulation model
Why are models useful in instantiating and integrating different theories?
Models allow us to instantiate and integrate different theories by providing a framework for testing and comparing their predictions.
What is the relationship between data and models in scientific research?
Data do not speak for themselves, but rather are interpreted through the lens of a model, which abstracts key features of the system being studied.
What is the drift diffusion model, and what type of model does it belong to?
A leading computational model that belongs to the class of evidence accumulation models
What is the advantage of using multiple models to explain a phenomenon, as in the case of the geocentric and heliocentric models?
Using multiple models allows us to compare their predictions and choose the one that best fits the data, leading to a better understanding of the phenomenon.
How can model parameters be thought of in the context of the drift diffusion model?
As control bars that configure a system's output, similar to buttons in a stereo system
What is one advantage of using the drift diffusion model in decision-making research?
It can account for response time in each decision context
What do the figures from Farrell & Lewandowsky (2018) illustrate in the context of the drift diffusion model?
Response caution, speed of evidence accumulation, and initial level of evidence or expectation
What is the primary advantage of using computational models, such as the drift diffusion model, in decision-making research?
They provide an excellent fit to data from various decision-making tasks
How do parameters in the drift diffusion model affect the model's predictions?
Different parameters produce different model predictions regarding the choice and response time
What is the relationship between statistical modeling and computational psychology in the context of decision-making research?
Computational psychology uses statistical models, such as the drift diffusion model, to understand decision-making processes
What is the primary objective of the iterative process described in the text, involving simulating data and updating parameter values?
To find the best-fitting values that allow the simulation to most closely replicate the empirical data
What type of models have been used to study various psychological phenomena, such as the effect of aging on recognition memory and the effect of depression on sensitivity to reward?
Evidence Accumulation Models, specifically the Drift Diffusion Model
What is the significance of linking drift-diffusion parameters to brain regions in computational psychology?
It allows for a better understanding of the neural basis of decision-making and choice
What is the limitation of the existing models of decision-making, according to the text?
They have not been integrated with the social identity approach
What is the role of salient identity in the identity-truth relationship, according to the text?
It influences decisions about what is true, and is related to memory of identity-relevant information
What is the significance of the study by Andersen and Pichert (1978) in the context of the identity-truth relationship?
It demonstrated the effect of randomly assigning participants to adopt different identities on their decisions about what is true
What is the primary goal of response time analysis in the context of evidence accumulation models?
To understand the underlying psychological processes that govern decision-making and choice
What is the role of statistical modeling in computational psychology, particularly in the context of evidence accumulation models?
It provides a mathematical framework for understanding the underlying psychological processes and making predictions about human behavior
This quiz covers the computational model of decision-making, specifically the drift diffusion model, which represents the psychological processes involved in evidence accumulation during decision making.
