â€Localization of Function:‬ †he theory that behaviors have their origin in specific areas of the brain. Damage‬ T â€to that part of the brain would result in an inability to carry out that behavior.‬ Iâ€n both an SAQ or an ERQ, you are expected to first describe and/or explain the theory. For the‬ â€command term‬â€describe‬â€, this means that you are identifying‬â€and defining the different components of‬ â€the theory.‬ â€Explain‬â€asks you to be specific about‬â€how the theory actually works - that is, identifying‬ â€assumptions made by the theory and/or explaining how the components of the theory interact.‬ â€Explaining localization of function‬ †istributive processing:‬â€The theory that behavior‬â€is the result of interaction between several‬ D â€parts of the brain and not strictly localized to a singular part of the brain.‬ †quipotentiality:‬â€the theory that the brain has the‬â€capacity in the case of injury to transfer‬ E â€functional memory from the damaged portion of the brain to other undamaged portions of the‬ â€brain.‬ †ocalization of function:‬ â€The theory that behaviors‬â€have their origin in specific areas of the‬ L â€brain. Damage to that part of the brain would result in an inability to carry out that behavior.‬ †elative localization‬â€: The theory that although one part of the brain may play a key role in a‬ R â€behavior, several parts of the brain also play a lesser role in that behavior.‬ â€Strict localization‬â€: The theory that behaviors can be attributed to a single area of the brain.‬ †or an SAQ, you need to be able to describe/explain one study. This means that you have to be‬ F â€able to describe the aim, procedure, and findings of the study. To explain it, you must link it to the‬ â€theory or concept in the question. In an ERQ, you should know two pieces of research. In addition,‬ â€to describing the aim, procedure, and findings, you need to be able to evaluate the research. The‬ â€use of correct terminology when describing a study - for example, correctly identifying the research‬ â€method - is an important aspect of the top mark band.‬ â€Key study 1. Maguire (2000)‬ †he aim of‬â€Maguire (2000)‬â€was to see whether the brains of London taxi drivers would be‬ T â€structurally different from the average person as a result of their exceptional knowledge of the city‬ â€and the many hours that they spend behind the wheel navigating the streets of London.‬ †he researchers compared MRI scans of 16 right-handed male London taxi drivers with the scans of‬ T â€50 right-handed males who did not drive taxis. All taxi drivers had at least 1.5 years. The mean age‬ â€did not differ between the two groups.‬ †he study was correlational in nature as the IV is not manipulated by the researcher. The study was‬ T â€a single-blind study.‬ †ixel counting revealed that the posterior hippocampi of taxi drivers had more grey matter compared‬ P â€to those of control subjects. Voxel-based morphometry (VBM) showed that the volume of the right‬ â€posterior hippocampi correlated with the amount of time spent as a taxi driver. No differences were‬ â€observed in other parts of the brain.‬ â€Key study 2. Milner (1966)‬ †he aim of‬â€Milner's (1966)‬â€case study was to better‬â€understand the effects that the removal of‬ T â€hippocampi had had on patient HM. Method triangulation was used. In her research, Milner carried‬ â€out psychometric testing (e.g. IQ testing), direct observation of his behavior, interviews, and memory‬ â€tests.‬ †ilner found that HM could recall information from before the surgery, but was unable to form new‬ M â€episodic or semantic memories. In other words, HM had anterograde amnesia – the ability to form‬ â€new memories. This suggests that the hippocampus plays a key role in the consolidation of some‬ â€types of memory.‬ †M had a capacity for working memory since he was able to carry on a normal conversation. When‬ H â€asked to recall the number 584, HM was able to do so even 15 minutes later, apparently by means‬ â€of constant rehearsal. However, after the task was over, HM would not be able to recall the number.‬ †emories in the form of motor skills, i.e. procedural memories, were well maintained; for example,‬ M â€he knew how to mow a lawn. He also showed improvements in the performance of new skills such‬ â€as reverse mirror drawing in which he had to acquire new eye-hand coordination. Although he‬ â€showed improvement in the skill over time, he never remembered learning the skill.‬ †orkin (1992, 2003) carried out an MRI scan of HM’s brain to see the extent of the damage. It was‬ C â€possible to see that parts of HM’s temporal lobe, including the hippocampus and amygdala, had the‬ â€most damage. Damage to the hippocampus explains the problem of transferring short-term memory‬ â€to long-term memory‬ †emember that critical thinking is an essential part of the ERQs, but not of the SAQs. There are two‬ R â€key ways in which critical thinking is assessed. First, you need to be able to evaluate the research‬ â€that you use in your response. Secondly, you need to address the command term. The command‬ â€term may ask you to‬â€evaluate‬â€the theory or‬â€discuss‬â€the theory.‬ â€Evaluate‬â€means that you must‬ â€address both strengths and limitations of the theory.‬ â€Discuss‬â€is the broader command term allowing‬ â€you to discuss either the strengths or limitations of the theory, why it is difficult to study the theory or‬ â€the implications of the research.‬ â€Discussing localization of function‬ â€â€¬ â€Much of the research on localization is limited, using case studies of people with brain‬ â€damage or autopsies. The overall effect of the damage on the brain is not really clear.‬ â€â€¬ â€Very few behaviors appear to be strictly localized; research supports that most behaviors‬ â€are the result of the interaction of different parts of the brain.‬ â€â€¬ â€Attributing complex human behaviors to a single part of the brain is seen as a‬ â€reductionist approach to human behavior. This is seen, for example, in studies like‬ â€LeVay (1991)‬â€in which human sexuality is attributed‬â€to a single nucleus in the‬ â€hypothalamus.‬ â€â€¬ â€Although fMRI scans can reveal where activity is taking place in the brain during some‬ â€behaviors, the ability for people to carry out a range of behaviors in such scanners is‬ â€very limited.‬ â€â€¬ â€MRIs can be used to determine localization by observing areas of the brain with more‬ â€grey matter; however, these studies are correlational and do not determine causality.‬ â€Additionally, other areas of the brain may play a role but not show a significant increase‬ â€in grey matter in such scans.‬ †efinition: Localization of function refers to the concept that specific areas of the‬ D â€brain are responsible for specific psychological functions, such as emotions,‬ â€movement, or cognition.‬ †xplanation: In the context of IB Psychology HL, localization of function suggests‬ E â€that different parts of the brain are specialized for different tasks. For example, the‬ f†rontal lobe is associated with decision-making and problem-solving, the temporal‬ â€lobe with auditory processing and memory, and the hippocampus with memory‬ â€formation. This theory is often supported by studies of brain lesions, brain imaging‬ â€(e.g., fMRI), and neuropsychological research that show how damage to specific‬ â€areas of the brain can result in impairments in certain cognitive or emotional‬ â€functions.‬ †xample: The study of Broca's area (responsible for speech production) in patients‬ E â€with speech deficits due to brain damage illustrates the principle of localization.‬ â€The research of Paul Broca and Carl Wernicke on patients with aphasia supports‬ â€the idea that certain regions in the brain are specialized for language processing.‬ â€Emotion and Memory:‬ â€Conceptual understanding‬ Iâ€n both an SAQ and an ERQ, you are expected to first describe and/or explain the theory. For‬ â€describe, this means that you are identifying and defining the different components of the theory.‬ â€Explain asks you to be specific about how the theory actually works - that is, identifying assumptions‬ â€made by the theory and/or explaining how the components of the theory interact.‬ â€Explaining flashbulb memories‬ †drenaline:‬â€a hormone linked to the human flight-or-fight‬â€response that appears to play a role‬ A â€in the creation of flashbulb memories.‬ â€Amygdala:‬â€the part of the brain that is responsible‬â€for the encoding of emotional memories.‬ †pisodic memory:‬â€the recollection of specific events,‬â€situations, and experiences. Episodic‬ E â€memory is autobiographical.‬ †lashbulb memories‬â€: a highly detailed, exceptionally‬â€vivid 'snapshot' of the moment and‬ F â€circumstances in which surprising and consequential news was learned about.‬ Iâ€mportance-driven model‬â€: This model expanded on the‬â€original model by Brown and Kulik.‬ â€The model argues that the personal significance of an event plays a key role in whether a‬ â€flashbulb memory is encoded.‬ †emember when describing flashbulb memories, there are several important components. Our prior‬ R â€knowledge (schema) helps us to decide whether something is important or not. For example, if I did‬ â€not know who Michael Jackson was, I would not be surprised by his death or feel that it was‬ â€important to my life.‬ Iâ€n addition, emotions - specifically, surprise - plays a key role in the encoding of the memory.‬ â€Psychologists argue that this is the "biological mechanism;" adrenaline may interact with the‬ â€amygdala - leading to the vividness and emotion tied to the memory.‬ †inally, "big news" is often talked about a lot. This is overt rehearsal which also helps to create the‬ F â€flashbulb memory - but may also lead to distortion.‬ â€Understanding research‬ †or an SAQ, you need to be able to describe/explain one study. This means that you have to be‬ F â€able to describe the aim, procedure, and findings of the study. To explain it, you must link it to the‬ â€theory or concept in the question. In an ERQ, you should know two pieces of research. In addition,‬ â€to describing the aim, procedure, and findings, you need to be able to evaluate the research. The‬ â€use of correct terminology when describing a study - for example, correctly identifying the research‬ â€method - is an important aspect of the top mark band.‬ â€Key study 1. Brown and Kulik (1977)‬ †rown & Kulik (1977)‬â€asked 40 black and 40 white American‬â€male participants to fill out a‬ B â€questionnaire regarding the death of public figures - such as President John F Kennedy and civil‬ â€rights leader Martin Luther King Jr - as well as of someone they personally knew. They were asked‬ â€a series of questions about the event including:‬ â€â€¬ â€Where were you when you heard about the event?‬ â€â€¬ â€Who was with you when you heard about the event?‬ â€â€¬ â€What were you doing when you heard about the event?‬ â€â€¬ â€How did you find out about the event?‬ â€â€¬ â€How did you feel when you heard about the event? (to indicate the level of emotion)‬ â€â€¬ â€How important was this event in your life? (to indicate personal relevance)‬ â€â€¬ â€How often have you talked about this event? (to indicate rehearsal)‬ †he researchers found that 90% of the participants recalled a significant amount of detail about the‬ T â€day when Kennedy was assassinated. Most participants had very detailed memories of the death of‬ â€a loved one. However, there was a difference in their memories of the assassination of public‬ â€officials, based on the personal relevance of the event to the participant. 75% of black participants‬ â€had flashbulb memories of the murder of Martin Luther King, compared to 33% of white participants.‬ â€Key study 2. Neisser and Harsh (1992)‬ â€Neisser & Harsch (1992)‬â€carried out a study to see‬â€if flashbulb memories could be distorted.‬ †n the morning after the Challenger disaster – less than 24 hours after the event - 106 university‬ O â€students were given a questionnaire. They were asked to write a description of how they heard the‬ â€news and then asked questions similar to those in Brown & Kulik’s study.‬ †½ years later, 44 of the original participants were given the same questionnaire to fill in again. This‬ 2 â€time they were also asked for each response to rate how confident they were of the accuracy of their‬ â€memory on a scale from 1 to 5.‬ †emi-structured interviews were carried out a few months later in order to determine if the‬ S â€participants would repeat what they had written a few months earlier or revert to the original memory.‬ â€At the end of the interview, the participants were shown their original 1986 reports in their own‬ â€handwriting.‬ †he researchers found that the mean score for accuracy was less than 3/7 of the questions.‬ T â€However, the average level of confidence was 4/5. In the interview, even when given cues to help‬ â€them recall the original memory, most of the participants confirmed their changed memory, rather‬ â€than their original one.‬ †emember that critical thinking is an essential part of the ERQs, but not of the SAQs. There are two‬ R â€key ways in which critical thinking is assessed. First, you need to be able to evaluate the research‬ â€that you use in your response. Secondly, you need to address the command term. The command‬ â€term may ask you to‬â€evaluate‬â€the theory or‬â€discuss‬â€the theory.‬ â€Evaluate‬â€means that you must‬ â€address both strengths and limitations of the theory.‬ â€Discuss‬â€is the broader command term allowing‬ â€you to discuss either the strengths or limitations of the theory, why it is difficult to study the theory or‬ â€the implications of the research.‬ â€Discussing emotion and memory‬ â€â€¬ â€There is biological evidence that supports the role of emotion in memory formation - for‬ â€example, McGaugh & Cahill (1995) and Sharot (2007).‬ â€â€¬ â€Neisser argues that it is one's level of confidence, not accuracy, which defines FBM.‬ â€â€¬ â€There are cultural differences that indicate that rehearsal may play the most important‬ â€role in the development of FBM.‬ â€â€¬ â€Often with real-life research on flashbulb memories, it is impossible to verify the accuracy‬ â€of the original memories.‬ â€â€¬ â€It is not possible to measure one's emotional state at the time of an event - thus making‬ â€it impossible to demonstrate a clear causal explanation.‬ †efinition: This theory explores the relationship between emotions and the‬ D â€formation, storage, and retrieval of memories. It suggests that emotional‬ â€experiences are more likely to be remembered because of the activation of certain‬ â€brain regions, like the amygdala.‬ †xplanation: In the context of IB Psychology HL, the theory emphasizes how‬ E â€emotions can impact memory processes. Strong emotional experiences are often‬ â€stored more vividly and are recalled more easily than neutral events. This is partly‬ â€because the amygdala, a brain structure involved in processing emotions, interacts‬ â€with the hippocampus (involved in memory storage), making emotional memories‬ â€more durable. The theory also explores how stress hormones (like cortisol) can‬ â€enhance memory encoding during emotionally charged events.‬ †xample: The research of Sharot et al. (2007) on flashbulb memories, which are‬ E â€highly detailed and vivid memories of significant events (such as 9/11), illustrates‬ â€the influence of emotion on memory. The study found that people were more likely‬ â€to recall emotional aspects of the event than neutral details.‬ â€Social Cognitive Theory:‬ â€Conceptual understanding‬ Iâ€n both an SAQ or an ERQ, you are expected to first describe and/or explain the theory. For‬ â€describe, this means that you are identifying and defining the different components of the theory.‬ â€Explain asks you to be specific about how the theory actually works - that is, identifying assumptions‬ â€made by the theory and/or explaining how the components of the theory interact.‬ â€Explaining Social Cognitive Theory‬ â€When writing about social cognitive theory, the following concepts should be explained:‬ †ttention, retention, motivation, potential‬â€: The‬â€cognitive "mediating processes" that‬ A â€Bandura argued play a role in whether we will imitate a model or not. The individual needs to‬ â€pay attention to the behavior and its consequences and form a mental representation of the‬ â€behavior. It is important that a memory of the behavior is formed to be performed later by the‬ â€observer. There has to be the desire to imitate the behavior - as well as the ability to do so.‬ †actors influencing imitation‬â€: In addition to the‬â€four key mediating processes, there are‬ F â€other factors that may affect whether we imitate a model. These include whether the model is‬ â€a member of our in-group, whether we like the model, whether we like the reward that the‬ â€model received, and whether the model's behavior is consistent over time.‬ â€Self-efficacy‬â€: a person's belief in his or her ability‬â€to succeed in a particular situation.‬ â€Social learning‬â€: Learning through the observation‬â€of the behaviors of others.‬ †icarious reinforcement‬â€: When a learner observes someone they identify with and the role‬ V â€model receives a reward, the learner is motivated to imitate the behavior as if they had been‬ â€rewarded themselves. This is also the case with vicarious punishment.‬ â€Understanding research‬ †or an SAQ, you need to be able to describe/explain one study. This means that you have to be‬ F â€able to describe the aim, procedure, and findings of the study. To explain it, you must link it to the‬ â€theory or concept in the question. In an ERQ, you should know two pieces of research. In addition,‬ â€to describing the aim, procedure, and findings, you need to be able to evaluate the research. The‬ â€use of correct terminology when describing a study - for example, correctly identifying the research‬ â€method - is an important aspect of the top mark band. You can read more about both of these‬ â€studies‬â€here‬â€.‬ â€Key study 1. Joy et al (1986)‬ †oy, Kimball & Zabrack‬â€(1986) conducted their study‬â€in three small towns in British Columbia,‬ J â€Canada. Television was introduced into the Notel community in 1973. In two other communities, they‬ â€also received the new channel but already had access to television. The psychologists observed‬ â€both physical and verbally aggressive behavior displayed by elementary school children on the‬ â€playground before Notel received a television channel and then two years after Notel received one‬ â€Canadian channel. There were 120 children in the sample. In addition, teacher and peer ratings of‬ â€aggressive behavior and information about television viewing habits were obtained.‬ †he aggressive behavior of children in Notel increased significantly from 1973 to 1975, whereas, the‬ T â€aggressive behavior of children in the other two towns did not change significantly over the same‬ â€period. The peer and teacher ratings supported the findings.‬ â€Key study 2. Charlton et al (2002)‬ †harlton et al‬â€(2002) carried out a study on the remote‬â€island of St Helena, where television was‬ C â€introduced in 1995, to investigate the influence of television on aggression in children. Cameras‬ â€were set up on the playgrounds of two primary schools. The behavior of 160 children (ages 3 - 8‬ â€years) was observed before and after the introduction of television.‬ †nalysis of hundreds of hours of videotape, backed up by interview data from teachers, parents, and‬ A â€some of the older children, showed no increase in anti-social behavior among the children of St‬ †elena. The behavior before the arrival of television had been maintained after five years of‬ H â€exposure to violent television.‬ â€Critical thinking‬ †emember that critical thinking is an essential part of the ERQs, but not of the SAQs. There are two‬ R â€key ways in which critical thinking is assessed. First, you need to be able to evaluate the research‬ â€that you use in your response. Secondly, you need to address the command term. The command‬ â€term may ask you to‬â€evaluate‬â€the theory or‬â€discuss‬â€the theory.‬ â€Evaluate‬â€means that you must‬ â€address both strengths and limitations of the theory.‬ â€Discuss‬â€is the broader command term allowing‬ â€to discuss either the strengths or limitations of the theory, why it is difficult to study the theory or the‬ â€implications of the research.‬ â€Evaluating Social Cognitive Theory‬ â€When evaluating Social Cognitive Theory, you may consider the following points:‬ â€â€¬ â€The theory can be applied to explain a lot of different behaviors. The theory has high‬ â€heuristic validity‬â€.‬ â€â€¬ â€The theory is difficult to test under‬â€naturalistic‬â€conditions‬â€where it is difficult to control‬ â€for extraneous variables.‬ â€â€¬ â€There are several‬â€constructs‬â€that are difficult to‬â€measure - for example, motivation,‬ â€self-efficacy, and one's level of attention.‬ â€â€¬ â€The theory has a‬â€strong bias‬â€toward the "nurture"‬â€side of the argument. Today‬ â€psychologists would argue that social learning interacts with our physiology, leading to‬ â€behavior. On its own, social learning cannot explain individual differences.‬ â€â€¬ â€Bandura proposed several variables that may increase the likelihood that a behavior will‬ â€be imitated. This increases the‬â€predictive power‬â€of the theory.‬ â€â€¬ â€There is‬â€biological support‬â€for the theory. Modern‬â€biological research indicates that‬ â€mirror neurons may play an important role in learning.‬ †efinition: Social Cognitive Theory (SCT), developed by Albert Bandura,‬ D â€emphasizes the role of observational learning, imitation, and modeling in behavior‬ â€acquisition. It asserts that learning occurs not only through direct experience but‬ â€also through watching the actions of others and the consequences of those actions.‬ †xplanation: In the context of IB Psychology HL, Social Cognitive Theory‬ E â€explores how behavior is influenced by social interactions and cognitive processes.‬ â€SCT suggests that individuals learn by observing others, particularly in a social‬ â€context, and then mimic or internalize behaviors. Key concepts within SCT include‬ â€attention (focusing on a model), retention (remembering the behavior),‬ â€reproduction (being able to replicate the behavior), and motivation (the desire to‬ â€perform the behavior based on expected outcomes). Bandura's concept of‬ â€self-efficacy also plays a role, as individuals are more likely to engage in behaviors‬ â€they believe they can successfully execute.‬ †xample: One of the most famous studies supporting Social Cognitive Theory is‬ E â€Bandura's Bobo Doll experiment (1961). In this study, children observed an adult‬ â€behaving aggressively toward a Bobo doll and later replicated that behavior‬ â€themselves when given the opportunity, demonstrating the influence of‬ â€observational learning on aggression.‬ †ach of these theories offers a different lens through which to understand human‬ E â€behavior, cognition, and emotion, and they have been fundamental in the‬ â€development of psychology as a field of study, particularly within the IB‬ â€curriculum.‬
