Introduction to cognitive psychology. Free study set.
Subject: humanities
Cognitive psychology is a field that scientifically investigates how the mind works. Which of these areas would it primarily focus on?
Answer: How people perceive information, remember events, and solve problems.
Cognitive psychology specifically studies mental processes such as perception, attention, memory, language, problem-solving, and decision-making. It aims to understand these internal workings of the mind.
The emergence of cognitive psychology is often referred to as a 'revolution' because it represented a significant shift in focus within the field of psychology. What was the primary change in focus that characterized this 'cognitive revolution'?
Answer: A transition from studying observable behaviors to investigating internal mental processes.
The 'cognitive revolution' marked a fundamental change in psychology, moving away from the behaviorist focus on external actions and towards the scientific study of internal mental operations like perception, memory, and language.
Which prominent figure is recognized for their foundational work in cognitive psychology, including their 1967 book that helped define the field? {0}
Answer: Neisser
Ulric Neisser's 1967 book, 'Cognitive Psychology', was a landmark publication that helped consolidate and define the emerging field, making him a key figure in its development.
What is the core assumption in cognitive psychology about how the mind can be understood? {0}
Answer: information-processing system
Cognitive psychology views the mind as a system that processes information, much like a computer. This allows researchers to study mental processes by analyzing how information is taken in, stored, and used.
You are studying in a busy coffee shop, but you manage to concentrate only on your textbook, tuning out the conversations and music around you. Which cognitive process are you primarily using?
Answer: Selective attention
Selective attention is the process of focusing on one particular input or task while actively ignoring other distractions. In this scenario, you are selecting your textbook as the focus and ignoring the coffee shop environment.
The "cocktail party effect" demonstrates that even when you are using selective attention to focus on one conversation, certain stimuli can still capture your awareness. What is the most common example of such a stimulus mentioned in the research?
Answer: Someone mentioning your name in another conversation
The "cocktail party effect" specifically highlights that even when selectively attending to one conversation, personally relevant information, such as hearing your own name, can still break through your attentional filter and grab your attention.
Why does performance often drop when someone attempts to perform two tasks simultaneously?
Answer: Both tasks compete for the same limited mental resources.
Divided attention means trying to do two things at once. The problem arises when these tasks require the same kind of mental effort or processing capacity, leading to a decrease in performance for both.
A student is intensely focused on taking notes during a lecture and completely fails to notice their friend waving at them from across the room. Which phenomenon best describes this situation?
Answer: Inattentional blindness
Inattentional blindness occurs when a person fails to notice an unexpected stimulus that is in plain sight because they are focused on another task. The student's intense focus on note-taking caused them to miss the friend waving.
What is the primary characteristic that defines explicit memory?
Answer: It requires conscious effort to recall information.
Explicit memory is characterized by the need for conscious recall. You have to actively think about and retrieve the information.
Which of the following scenarios primarily relies on semantic memory?
Answer: Knowing that the Earth revolves around the Sun.
Semantic memory stores general facts and knowledge about the world, like scientific facts. Recalling your last birthday party is episodic memory, riding a bicycle is procedural memory, and recognizing a face more quickly is priming.
Which of the following scenarios best illustrates the use of implicit memory?
Answer: Automatically hitting the brake when a car suddenly stops in front of you.
Implicit memory involves unconscious recall, like motor skills or automatic reactions. The other options describe explicit memory, which requires conscious effort to retrieve facts or personal experiences.
What type of implicit memory allows you to perform skills like riding a bicycle without conscious thought? {0}
Answer: procedural
Procedural memory is a type of implicit memory that stores information about how to perform different actions and skills.
Patient H.M.'s case demonstrated a 'dissociation of systems' in memory. What does this mean?
Answer: The ability to form new explicit memories was lost, while implicit memory formation remained intact.
Patient H.M. could not form new episodic (explicit) memories after his hippocampus was removed, but he could still learn new motor skills (a form of implicit memory). This showed that these memory systems operate independently.
Which specific brain region was removed in Patient H.M.'s surgery, leading to his inability to form new episodic memories? {0}
Answer: hippocampus
The removal of H.M.'s hippocampus was directly linked to his profound inability to form new episodic memories.
Imagine you are trying to learn a list of new vocabulary words. Which approach would most likely help you remember them best?
Answer: Writing down each word's definition and thinking about how it relates to other words you know.
Semantic encoding, which involves understanding the meaning of information and connecting it to existing knowledge, is considered the deepest level of processing and leads to the best recall.
According to the levels of processing theory, which type of encoding produces the best recall? {0}
Answer: semantic
Semantic encoding involves processing information based on its meaning, which is the deepest level of processing and results in the strongest memories.
A student spends hours studying for a history exam in a quiet, dimly lit room. According to the principle of encoding specificity, where would they most likely perform best on the exam?
Answer: In the same quiet, dimly lit room where they studied.
Encoding specificity suggests that memory retrieval is most effective when the context present during retrieval matches the context present during encoding. Therefore, taking the exam in a similar environment to where the studying occurred would likely lead to better recall.
A student has an important test in two weeks. Which study strategy best applies the spacing effect?
Answer: Studying for three hours every day for the next two weeks.
The spacing effect suggests that distributing study time over a longer period is more effective than concentrating it into a short period. Studying every day for two weeks is the best example of distributed practice.
What is the term for studying material in one long session, which the spacing effect suggests is less effective than distributed practice? {0}
Answer: cramming
The source text explicitly defines 'massed practice' as 'cramming,' which is the opposite of distributed practice and less effective according to the spacing effect.
According to the testing effect, which study method is most effective for strengthening long-term memory?
Answer: Actively recalling information through self-quizzing or practice tests.
The testing effect states that actively retrieving information from memory, such as through self-quizzing or practice tests, is more effective for strengthening memory than simply re-reading material.
Which statement best describes the pattern of forgetting identified by Ebbinghaus?
Answer: Memory loss is rapid immediately after learning, then gradually slows down.
The Ebbinghaus forgetting curve shows a steep drop in retention shortly after learning, followed by a more gradual decline. This means you forget a lot quickly, then the rate of forgetting slows.
According to Ebbinghaus's research, approximately what percentage of newly learned information might be forgotten within the first hour without review? {0}
Answer: 60
Ebbinghaus's research indicated that a significant portion of new information, around 60%, is forgotten very quickly, often within the first hour, if it's not reviewed.
A student is trying to remember the name of their new psychology professor, Dr. Virtanen. However, they keep accidentally calling her by their old professor's name, Dr. Smith. Which type of interference is this student experiencing?
Answer: Proactive interference
Proactive interference occurs when old information (the old professor's name) blocks the recall of new information (the new professor's name). The previously learned information is getting in the way of remembering the new.
After learning Spanish for two years, a student finds it difficult to remember vocabulary from the French classes they took three years ago. What type of interference best describes this situation?
Answer: Retroactive interference
Retroactive interference is when new information (learning Spanish) makes it harder to recall old information (French vocabulary). The more recently learned material is interfering with the older memory.
What is the main idea behind describing memory as "reconstructive"?
Answer: Each time we recall an event, our brain actively rebuilds the memory, potentially incorporating new information.
The concept of reconstructive memory means that remembering isn't a simple playback. Instead, our brains actively piece together information, and this process can be influenced by various factors, including new details or suggestions.
The Loftus and Palmer (1974) study provided evidence for memory being reconstructive by demonstrating what?
Answer: The way a question was phrased about a car crash influenced participants' estimates of car speed.
Loftus and Palmer showed that simply changing a word in a question (like "smashed" versus "hit") could alter how participants remembered the speed of cars in a video. This illustrates how external information can influence the reconstruction of a memory.
A witness to a minor fender-bender is later asked by a police officer, 'How fast was the blue car going when it *smashed* into the red car?' The witness then reports a higher speed than they initially estimated. What psychological phenomenon does this scenario best illustrate?
Answer: The misinformation effect
The misinformation effect occurs when misleading information presented after an event alters a person's memory of that event. In this case, the word 'smashed' is the misleading information that influences the witness's speed estimate.
What term describes when misleading information presented after an event alters a person's memory of that event? {0}
Answer: misinformation effect
The misinformation effect is the phenomenon where post-event information can distort a person's memory, sometimes leading to the creation of false memories.
