Exam 1 Flashcards
Clever Hans
A horse who was claimed to perform arithmetic tests but really was just watching the reaction of his trainer
Process of a scientific study
Theory, Research Questions, Research Designs, Hypothesis, Data
Theory
A proposal of how things work together
Research Questions
Questions that needs to be answered to determine if theory is correct
Research Designs
A set of method investigating these questions
Hypothesis
A specific prediction about what will happen in the context of the research design
Operationalize
Translate the variable we want to assess into quantifiable measurements
Correlation
Insight into relationship between two variables, runs from -1 to 1
Third variable
Usually hidden variable causing a correlation between two variables
Key parts of an experiment
Manipulation, Measurements, Control of extraneous factors, Randomization/Random assignment
Manipulation
The variable we change between conditions
Control of extraneous factors
Control
Measurements
Operationalize and measure
Randomization/Random Assignments
Randomly assignment
Strengths of Correlation
Widely applicable, naturalistic
Weakness of Correlation
The directionality problem –> cannot infer causation
Strengths of Experiments
Can infer causation
Weakness of Experiments
Not widely applicable, artificial
Induction
Drawing conclusions from specific observations
Key cornerstones of psychology
Accuracy, consistency, scope, simplicity, fruitfulness
Falsifibility
The idea that if something was scientific, it would be able to be proven false
Studies never ____ hypothesis it only ____
prove, support
Inductive reasoning
Taking current observations and drawing conclusion from it
Deductive reasoning
Taking a conclusion or general principles and applying to specific circumstances
Level of Analysis
A single phenomenon can be explained at different levels simultaneously
Generating Causality
Science that is systematic, testable, and generates reliable data allows us to determine causality and generalize our conclusions
Constructivism
knowledge is constructed through an interaction of what we already know and what we experience.
Schema
principles through which we understand the world
Sensorimotor
age 0-2 interaction with the physical world, the here and now, object permanence, the hidden task hiding an object underneath sheets and asking babies to search for it
Preoperational
Age 2- 6. Use of symbolic languages, imagination and language, still struggling to understand multiple schemas and mentally manipulate them, the conservation task with babies not being able to manipulate water volume in their heads
The Concrete Operational Stage
Age 6-12. Begin to think logically about concrete events
Begin to understand the concept of conservation; that the amount of liquid in a short, wide cup is equal to that in a tall, skinny glass, for example
Thinking becomes more logical and organized, but still very concrete
Begin using inductive logic, or reasoning from specific information to a general principle
The Formal Operational Stage
12-adult hood Begins to think abstractly and reason about hypothetical problems
Begins to think more about moral, philosophical, ethical, social, and political issues that require theoretical and abstract reasoning. Begins to use deductive logic, or reasoning from a general principle to specific information. May need formal education to reach this stage.
Egocentrism
Pre operational stage, only understand the world from their perspective
Hill task
Researcher spins the hill and ask the child what the researcher now sees, child only answers with what they see
Hide and seek
Hiding themselves only
False Belief Task
They can’t appreciate that their knowledge is different from someone else’s. If sally hides the ball, she assumes the other kid will know where it is
