Chapter 1 How do we observe someone’s flirting behavior? If we were to observe someone's flirting behavior it would be systematic observations such as looking at body language, intimacy, attention and the way they act. Elements of science: Systematic Observation: Observe, measure,record Hypotheses and theories: Develop, test Democracy: Open discussion and debates Cumulation: BUILD Psychological science A branch of science dealing with the mental processes and behavior of individuals and groups {applied science} —>application of scientific knowledge to practical problems or situations. Chapter 1: Scientific Thinking, Physiological Research and Res Experimental Research Does highlighting improve retention of information? 1. Randomly draw names 2. Assign them to highlight 3. Other half no highlighting *Confounding variables; Placebo effect Participant demands affect outcomes Experimenter expectations influence outcomes Correlation studies Correlation is not causation Facebook —> Depression Depression —> Facebook No friends—>Facebook/ Depression Correlation coefficient Relationships —------------> Correlation Coefficient Time on social media and exam scores —-> r = -.50 Animal lover and owning a cat —--> r =.75 Having a sweet tooth and number of desserts consumed —> r =.20 Surveys Describe how surveys were used in a caffeine study: there can be questions asked specifically about what is being studied, demographic information, how likely would you recommend it, age. Benefits: can be anonymous, things can be asked on a distinct level and also you can lie on a survey. Quasi- experimental design 1. No random assignment 2. Different independent variables 3. Problems Methods and Trade- offs 1. Mass misconception Key components to a Statistical Thinking or Investigation 1. Planning the study 2. Examining the data 3. Inferring from the data 4. Drawing conclusions Distributional thinking Analyzing the pattern of data variation called the distribution of the variable often reveals insights. Develop an example of a distribution of one variable that you encounter in your life, what is the variable and how does it vary? One research would be when researchers studied cancer patient reading levels Statistical significance 1. Control- are there other variables in the infant study that the researchers missed? 2. Probability/ p value 3. Level of significance - p <.05 Cause and effect 1. Statistical tendencies 2. Random assignments If the p value is small (under.05) the observed mean scores were not coincidental Scientific reasoning and theories Hypothesis - predictions about the way the world works that are testable Sample recruitment Experiment Inductive reasoning Features of good scientific theory Accuracy Scope Fruitfulness Simplicity Consistency Falsifiability Do standing desk increase productivity Three outcomes: 1. Results Support Hypothesis 2. Results Contradicts a) Sitting → standing b) No difference between groups Levels of Analysis 1. Social / Culture 2. Behavioral 3. Cognitive 4. Biological Research in the real world Internal validity- The degree to which a relationship between two variables has been unambiguously established or the degree to which a study allows unambiguous causal inferences. External validity- The degree to which a study ensures that potential findings apply to settings and samples other than the ones being studied Ecological validity - The degree to which an effect has been obtained under conditions that are typical for what happens in everyday life Studying daily experiences Day reconstruction method (DRM)- participants report experiences of a given day by systematically reconstructing. Electronic activated recorder (EAR) Chapter 01 pdf notes Replication There are different types of replication, first one being exact replication(also known as direct replication). The second type of replication is called conceptual replication. Key Components to a statistical investigation are: 1)Planning the study: Start by asking a testable research question and deciding how to collect data. For example, how long was the study period of the coffee study? How many people were recruited for the study, how were they recruited, and from where? How old were they?What other variables were recorded about the individuals, such as smoking habits, on the comprehensive lifestyle questionnaires? Were changes made to the participants’ coffee habits during the course of the study? 2)Examining the data: What are appropriate ways to examine the data? What graphs are relevant, and what do they reveal? What descriptive statistics can be calculated to summarize relevant aspects of the data, and what do they reveal? What patterns do you see in the data? Are there any individual observations that deviate from the overall pattern, and what do they reveal? For example, in the coffee study, did the proportions differ when we compared the smokers to the non-smokers? 3)Inferring from the data: What are valid statistical methods for drawing inferences “beyond” People around the world differ in their preferences for drinking coffee versus drinking tea. Would the results of the coffee study be the same in Canada as in China? the data you collected? In the coffee study, is the 10%–15% reduction in risk of death something that could have happened just by chance? 4)Drawing conclusions: Based on what you learned from your data, what conclusions can you draw? Who do you think these conclusions apply to? (Were the people in the coffee study older? Healthy? Living in cities?) Can you draw a cause-and-effect conclusion about your treatments? Chapter 2: Neurons, the brain and the nervous system History of neurons as cells Santiago Ramon y Cajal Declares cells are discrete Structural/ functional units of the nervous system Called cell theory Types of cells in the brain Types of neurons in your brain Motor neurons → responsible for movements, a cell of the central nervous system Sensory neurons → for touch, feeling, taste anything with a sense, part of the peripheral neurons Interneurons → interneurons are found exclusively in the central nervous system Structural classification of neurons 1. Multipolar neurons- motor neurons but also depends on where they are in your body or brain they can serve as different functions 2. Bipolar neurons- serves as an interneuron 3. Unipolar neurons Glial cells- supporting cells Oligodendroglia (CNS) / Schwann (PNS) Microglia Astrocytes - provide nutrients to the neurons, structural support for the brain, form blood brain barrier (BBB) Blood brain barrier protects your brains from any harmful substance, not everything can go into your brain, in charge of providing nutrients to your brain. Communication within and between neurons Separation of ions 1. Anions 2. Potassium 3. Chloride 4. Sodium Pressure acting on ions 1. Diffusion 2. Electrostatic pressure Action Potential Characteristics 1. All or nothing 2. Depolarized past threshold of excitation 3. Results in neurotransmitter release 4. Change in neuron potential during action potential *Na+ channels open *Both diffusion and electrostatic pressure pushes Na+ into the cell *As Na+ is rushing in, K+ channels open Action Potential in Myelinated Axons Myelin speeds the process: 1. Action potential occurs at each Node of Ranvier 2. Saltatory Conduction Neurotransmission Neurons: How the CNS Communications Neurotransmitter release: 1. Binds in lock and key fashion 2.

Consciousness is not like an off-on switch but is more like a dimmer switch that can be turned from low to across a continuum 2. Low consciousness includes sleep, hypnosis and daydreaming 3. Higher consciousness requires greater effort and sustained focus 4. Sleep is a unique state of consciousness in that it is a drive state and basic need for physiological and physical well-being 5. People have long used drugs as means of altering their states of consciousness including minimizing pain, promoting recreational pleasure and exploring spiritual Language Introduction Capacity to use complex language Humans have a wider range of ways to communicate complex , abstract thought Language use and human sociality are inseparable parts Use of language Language use is ubiquitous Many forms: written, spoken and body Goal: transmit information Important factors: 1. Common ground 2. Audience design 3. Situation models 4. Priming Important factors: Common ground: set of knowledge that the speaker and listener share, and they assume that they share Audience design: tendency for speakers to design their utterances for their audience by considering the audience knowledge Situation models: those involved in the conversation begin to use similar words and grammar, and many other aspects of language use converge Priming : one concept reminds you about other related concepts; builds similar situation models in everyone's mind. Components: Lexicon 1. Words and expression Syntax 1. Grammatical rules for arranging words and expressions together. Content of language Topics of conversation: Ingroup and outgroup 60%-70% of everyday conversation is gossip Allows humans to share representations about and regulate their social world Make more friends and enlarge one's own group Outgroups : other groups Topics of conversation: Linguistic intergroup bias Tendency to talk about positive attributes of the ingroup and negative attributes of the outgroup, using adjectives instead of verbs Ingroup members are viewed as generally and permanently good; outgroup members generally and permanently bad Negative attributes of the ingroup and positive attributes of the outgroup- verbs; one-time occurrence Social brain hypothesis: Dunbar 1996 Social effects have given humans an evolutionary advantage and larger brains Help humans to think more complex and abstract thoughts and more important , maintain larger ingroups Chapter 3 pdf notes Summary Consciousness remains one of the most enigmatic subjects in psychology and neuroscience, prompting questions about its nature, origins, and significance. This text discusses how consciousness can be studied through various scientific approaches, including neurocognitive functions that occur with and without conscious awareness. It emphasizes the need for a comprehensive understanding of consciousness, integrating insights from various disciplines such as psychology, philosophy, and neuroscience. The text highlights the uniqueness of individual conscious experiences, the challenges of understanding others’ consciousness, and the relationship between conscious experiences and neural activity. Additionally, it explores how consciousness influences memory, perception, body awareness, and decision-making processes, ultimately suggesting that subjective experiences have a valid place within scientific inquiry. Key Insights Consciousness is fundamental to human identity and cannot be entirely understood through the objective lens typically used in scientific inquiry. Distinctions between conscious and non-conscious processes are crucial for understanding how various mental functions operate. Neuroscientific methods, such as brain imaging, provide insights into how consciousness arises from neural interactions. Consciousness is influenced by multiple factors, including biological, social, and environmental elements. The experience of consciousness is subjective and differs from person to person, complicating efforts to generalize findings. Frequently Asked Questions What is consciousness and why is it considered a mystery? Consciousness is the state of being aware of and able to think about one’s own existence, thoughts, and surroundings. It is considered a mystery because, despite its fundamental role in human experience, its precise nature, origins, and mechanisms remain poorly understood. How does the brain generate conscious experiences? Conscious experiences are thought to arise from complex interactions between various brain regions. Neural synchronization and reciprocal exchanges of information among these areas are crucial for generating awareness. Can we infer consciousness in other beings, such as animals or AI? While some behaviors in animals and advanced AI may suggest consciousness, accurately inferring consciousness in non-human entities is challenging due to our limited understanding and inability to access their subjective experiences. What role does consciousness play in decision-making? Consciousness allows individuals to analyze and weigh factors when making decisions, but it can also create the illusion of free will, as some decisions may be influenced by unconscious processes that precede conscious awareness. Summary The text explores the complex nature of consciousness, discussing its various levels and their effects on behavior. It defines consciousness as awareness of oneself and the environment, distinguishing between high and low conscious states. The authors highlight the influence of subconscious factors on decisions and actions, illustrated through studies on subliminal messaging and priming. The text also delves into altered states of consciousness, such as hypnosis and sleep, explaining their characteristics and implications for behavior and therapy. Hypnosis, often misrepresented in media, is described as a state of heightened suggestibility and focused attention. Additionally, it covers the impact of psychoactive drugs and the physiological mechanisms behind different states of consciousness, emphasizing the importance of understanding these concepts for better psychological insights. Key Insights Consciousness encompasses a spectrum from high awareness to low awareness, affecting decision-making and behavior. Subliminal messaging and priming can significantly influence our thoughts and actions without conscious awareness. Hypnosis involves increased suggestibility and focused attention, which can be therapeutically beneficial despite misconceptions. Sleep is an active state of consciousness with distinct stages, crucial for mental and physical restoration. Psychoactive drugs alter consciousness and perception, classified into hallucinogens, depressants, and stimulants, each with unique effects and risks. Frequently Asked Questions What is consciousness, and how is it defined? Consciousness is the awareness of oneself, bodily sensations, thoughts, and the environment. It ranges from high awareness, where individuals are fully focused and engaged, to low awareness, where influences may operate subconsciously. How do altered states of consciousness, like hypnosis, differ from regular wakefulness? Altered states, such as hypnosis, involve increased focus and suggestibility, where individuals may respond to suggestions as if they were their own. This is different from regular wakefulness, where individuals have more control over their thoughts and actions.What role do psychoactive drugs play in altering consciousness? Psychoactive drugs, such as hallucinogens, stimulants, and depressants, can significantly impact perception, mood, and behavior by altering how the brain processes information and responds to stimuli. How does sleep affect cognitive function and behavior?Sleep is essential for mental and physical health, with different stages impacting memory consolidation, emotional regulation, and overall cognitive functioning. Lack of adequate sleep can lead to irritability, decreased attention, and impaired decision-making. Summary The module on attention explores the concept of selective attention, which allows individuals to focus on specific stimuli while ignoring distractions. It emphasizes the limitations of our cognitive capacity, highlighting how multitasking can impair performance, particularly in activities like driving. Key theories and models, including Broadbent’s Filter Model and Treisman’s Attenuation Model, illustrate how we process information based on physical features and meaning. The text discusses the implications of divided attention, particularly in relation to distracted driving, and the phenomenon of inattentional blindness, where significant stimuli are overlooked when attention is focused elsewhere. Overall, the module underscores the critical role of attention in processing information effectively in our daily lives. Key Insights Selective attention enables us to focus on specific stimuli while filtering out distractions.Cognitive capacity is limited, making multitasking challenging and often detrimental to performance.Different models of attention explain how we process information, with early selection focusing on physical features and late selection on meaning.Inattentional blindness demonstrates how we can miss significant information when our attention is directed elsewhere. Understanding attention is crucial for addressing issues like distracted driving, as cognitive distractions significantly impair performance. Frequently Asked Questions What is selective attention, and why is it important? Selective attention is the cognitive process of focusing on specific stimuli while ignoring others. It is crucial for efficient information processing and helps us navigate complex environments by allowing us to concentrate on relevant details. How does multitasking affect cognitive performance? Multitasking can impair cognitive performance as our brain has a limited capacity for processing information. Engaging in multiple complex tasks simultaneously often leads to decreased efficiency and increased likelihood of errors.What are the implications of inattentional blindness? Inattentional blindness refers to the failure to notice visible objects when attention is focused on another task. This phenomenon can lead to dangerous situations,such as accidents while driving, highlighting the need for awareness of our cognitive limitations. How can we enhance our attention skills? While our cognitive capacity is limited, we can enhance attention skills through practice and training. Engaging in activities that require focused attention and minimizing distractions can help improve our ability to concentrate effectively. Summary The text discusses the nature of mental concepts and categories, explaining how humans organize objects into categories based on shared properties and prototypes rather than strict definitions. It introduces the basic-level category, which offers an optimal level of specificity for categorization. The text explores various theories of concept representation, including prototype and exemplar theories, highlighting how knowledge influences concept learning. It addresses issues of typicality, fuzzy category boundaries, and how concepts are affected by cultural differences. The text concludes by emphasizing the significance of concepts in understanding the world and suggests that theories of concepts are evolving to incorporate diverse cognitive systems and cultural influences. Key Insights Human concepts are organized around prototypes and best examples rather than strict definitions.Basic-level categories strike a balance in specificity, making them easier for individuals to learn and recognize.Typicality influences interactions with categories, where some members are viewed as more representative than others. Theories of concept representation include prototype theory, which emphasizes summary features, and exemplar theory, which focuses on specific examples. Knowledge and cultural context significantly shape how concepts are learned and understood, leading to variations in categorization across different societies. Frequently Asked Questions What are the challenges in defining categories? Many familiar categories resist strict definitions due to their inherent messiness and diversity, leading to fuzzy boundaries and borderline members. How does typicality effect categorization? Typicality influences how easily individuals categorize objects, with more typical members being more readily identified and accepted as category representatives. What role does prior knowledge play in concept learning? Prior knowledge helps individuals learn new concepts more effectively, as they connect new information to existing mental frameworks. How do cultural differences impact concept formation? Cultural context influences the categorization and naming of objects, leading to variations in how different societies define and understand concepts. Summary The module on intelligence explores its historical context, major theories, and assessment strategies in psychology. Intelligence has long been a focal point in psychological research, with key figures like Alfred Binet and Charles Spearman shaping its understanding. Binet developed the first IQ test, while Spearman proposed the concept of a general intelligence factor. The module also addresses various types of intelligence, including emotional intelligence and Howard Gardner’s theory of multiple intelligences, emphasizing that intelligence encompasses a range of cognitive abilities. Additionally, the text discusses the ongoing debate over group differences in intelligence, particularly concerning gender, and the implications of mindset on performance. Ultimately, intelligence is portrayed as a complex and multifaceted construct influenced by both genetic and environmental factors. Key Insights Intelligence is a long-studied topic in psychology with significant historical contributions from figures like Binet and Spearman. The concept of intelligence includes various types, such as emotional intelligence and Gardner’s multiple intelligences. IQ tests, like the Stanford-Binet and WAIS, assess a wide range of cognitive abilities but are not without controversy regarding their predictive validity and potential biases. The “Flynn Effect” indicates that average IQ scores have increased over time, suggesting environmental influences on intelligence. Mindset plays a crucial role in intelligence performance, where a growth mindset can lead to better outcomes compared to a fixed mindset. Frequently Asked Questions What are the key historical figures in the study of intelligence? Key figures include Alfred Binet, who developed the first intelligence test, and Charles Spearman, who proposed the concept of a general intelligence factor known as “g.” How is intelligence measured in psychological assessments? Intelligence is commonly measured through standardized tests like the Stanford-Binet and Wechsler Adult Intelligence Scale, which evaluate various cognitive abilities. What is the “Flynn Effect” and what does it imply about intelligence? The Flynn Effect refers to the observed increase in average IQ scores over decades, suggesting that environmental factors such as education and nutrition play a significant role in intelligence development. How do gender and social factors influence differences in intelligence? Research indicates that differences in intelligence between genders may stem from a complex interplay of socialization, educational inequalities, and societal expectations rather than inherent biological factors. Summary The text by Yoshihisa Kashima explores the intricate relationship between language use and human sociality. It emphasizes that language is a fundamental tool for communication, enabling humans to construct and maintain their social world. The author illustrates how language is learned and utilized, particularly through examples like casual conversations that rely on shared knowledge or “common ground.” The development of Nicaraguan Sign Language among deaf children underscores the innate human capacity for language. Additionally, the text delves into the psychological consequences of language, such as its impact on memory and emotional processing, and discusses how language influences social dynamics, including gossip’s role in maintaining social relationships.

Key Insights Language is innate and learned, enabling complex communication and social interactions.The concept of “common ground” is crucial for effective conversation, allowing speakers and listeners to share knowledge. Gossip serves as a significant function of language, helping individuals navigate their social environment and maintain group cohesion.Language influences psychological processes, such as memory and emotional responses, highlighting its therapeutic potential.The Sapir-Whorf hypothesis suggests that language shapes thought, with linguistic practices reflecting cultural values and social structures. Frequently Asked Questions What is the significance of “common ground” in conversations? Common ground refers to the shared knowledge and understanding between conversation partners that facilitates communication and information exchange. It evolves as dialogue progresses, allowing participants to build upon each other’s ideas. How does gossip function as a social tool? Gossip allows individuals to communicate about their social world and relationships, fostering group cohesion and signaling social dynamics within a community. It serves as a mechanism for regulating social behavior and maintaining networks. In what ways does language influence psychological processes? Language affects how individuals perceive and remember experiences. Verbalizing emotions can alter emotional responses and improve psychological well-being, demonstrating the therapeutic potential of language use. What are the implications of the Sapir-Whorf hypothesis? The Sapir-Whorf hypothesis posits that the language we use can shape our thoughts and perceptions of the world. While it doesn’t completely determine our thoughts, habitual language use can influence cognitive processes and cultural values. Summary The “Theory of Mind” refers to the human ability to understand and interpret the mental states of others, which is crucial for effective social interaction. This cognitive capacity allows individuals to perceive intentions, beliefs, and emotions, thereby facilitating complex social behaviors such as teaching, collaboration, and moral judgment. The development of this ability begins in infancy and evolves over time, influenced by both biological and social factors. Individuals with autism often experience challenges in utilizing theory of mind, highlighting its importance in everyday interactions. The text outlines various mental processes involved in understanding others’ minds, such as goal recognition, empathy, joint attention, and perspective taking. It also discusses how folk explanations of behavior stem from this cognitive framework, revealing the innate human desire to make sense of actions and motivations. Key Insights Theory of mind is essential for social functioning, enabling individuals to interpret and predict others’ actions based on inferred mental states.The capacity to understand others’ minds develops from infancy and is a product of both evolution and social learning.Individuals with autism may struggle with theory of mind, demonstrating the significant impact of this cognitive ability on social interactions. Various processes contribute to theory of mind, including empathy, joint attention, and the ability to take another’s perspective.Folk explanations of behavior emerge from our theory of mind, as people seek to understand the intentions behind actions. Frequently Asked Questions What is the significance of theory of mind in human interactions? Theory of mind is crucial for understanding and predicting others’ behaviors, facilitating communication, teamwork, and moral reasoning. How does theory of mind develop in children? Theory of mind develops gradually in children, beginning in infancy as they learn to recognize agents and intentional actions, and becoming more complex with age. What challenges do individuals with autism face regarding theory of mind? Individuals with autism may have difficulty interpreting social cues and understanding others’ mental states, which can impede their social interactions. How do people use theory of mind to explain behaviors?
