Lear, the aging king of Britain, decides to step down from the throne and divide his kingdom evenly among his three daughters. First, however, he puts his daughters through a test, asking each to tell him how much she loves him. Goneril and Regan, Lear’s older daughters, give their father flattering answers. But Cordelia, Lear’s…
What qualities make someone a good leader? In Lord of the Flies who demonstrates this role of being a leader, and how is it being displayed? A leader is someone who has the ability to take control and charge of a group. A leader is there to guide, manage, and provide assistance to a group…
Ralph Ellison’s Invisible Man opens with a prologue describing the main character in time after the beginning of the body of the book. In the prologue, Ellison tells of the main character’s invisibility. It is not a physical invisibility, but rather he is not recognized, and therefore perceived, by the world at large. This is…
Humans as a race have come a long way since our introduction to earth. Today, our world is defined by systematic approaches and specific methods of living. The poem “Sophoclean” by Seamus Heaney touches on some of the historical characteristics of humanity and highlights the elements of our success as a species. A Marxist analysis…
The first scene starts with Banquo voicing his suspicions about Macbeth killing Duncan in order to become the King. He is aware that the witches had prophesized that his sons would become Kings. But he doesn’t let this thought obsess him. He is capable of controlling his thoughts and checking his ambitions unlike Macbeth which…
Sexual reproduction: production of offspring; union of male and female gametes Gametes: eggs and sperms cells in animals Sexual reproduction depends on Meiosis; specialized process of cell division; recombines DNA sequences, produces cells with half the number of chromosomes in somatic cells. (chromosome= reduction) Fertilization: nuclei of egg/ sperm fuse; producing zygote (# chromosomes typical…
Genetic linkage: genes located on same chromosome may be inherited together in genetic crosses. Linked Genes: Genes on same chromosomes Morgan- first to map genes; can’t directly measure distance between genes Do it indirectly– gene sitting far apart on a chromosome would be more likely to be separated from one another during meiotic crossing-over than…
Blending theory of inheritance: hereditary trait blend evenly in offspring through mixing of parent’s blood. Mendel studied heritable characteristics called characters; plant color and seed shape. Variation in character= Trait Monohybrid cross between to heterozygous parents (Dr x Dr) F1 generation will yield phenotypic ration of 3:1 (1/4 getting PP or pp, or ½ getting…
Genetic recombination needs: Homologous chromosomes; must differ from one another along one at least two spots Mechanism to bring into close proximity of each other Homology allows the DNA to line and recombine precisely. Cut and passing 4 DNA backbones results in 1 recombination event. Lederberg Experiment E.coli grown in minimal medium; contains water, organic…
Cell Cycle: nuclear division, cytokinesis Parental cell: genetic copies of parental cell 3 process: checks/ regulators for each step to ensure timely progression, replication process to synthesis DNA into two copies, interwoven “cables” and “motors” of mitotic cytoskeletons. Chromosomes: nuclear units of genetic information; DNA molecules combined with proteins. In eukaryotes, heredity information of nucleus…
Sexual response cycle – four stage cycle experienced during sexual arousal Excitement phase – arousal builds rapidly Plateau phase – respiration, heart rate, vasocongestion, and muscle tension continue to build until there is enough muscle tension to trigger orgasm Orgasm phase – males: rhythmic contractions of internal organs and muscle tissue surrounding the urethra project…
Motivation – process that influences the direction, persistence, and vigour of goal directed behaviour Perspectives on Motivation Instinct Theory and Modern Evolutionary Psychology Instinct (fixed action pattern) – an inherited characteristic, common to all members of a species, that automatically produces a particular response when the organism is exposed to a particular stimulus Theories faded…
Metabolism – body’s rate of energy utilization Two-thirds of energy used goes to support basal metabolism, the resting, continuous metabolic work of body cells Immediate energy supply information interacts with other signals to regulate food intake (hunger not necessarily linked to immediate energy needs) Homeostatic mechanisms are designed to prevent people from running low on…
Two types of reasoning: Deductive reasoning – reasoning from a general principle to a specific case Basis of formal mathematics and logic Viewed as stronger and more valid reasoning because conclusion cannot be false if premises are true Syllogism: If all humans are mortal (first premise), and Socrates is a human (second premise), then Socrates…
Language: History and Structure Language – a system of symbols and rules for combining these symbols in ways that can produce an almost infinite number of possible messages and meanings Three critical properties of language: Symbolic: Uses sounds, written signs, or gestures to refer to objects, events, ideas, and feelings Displacement – capacity of language…
Memory – processes that allow us to record and later retrieve experiences and information Memory as Information Processing Encoding – getting information into the system by translating into a neural code that your brain processes Storage – retaining information over time Retrieval – the process of accessing information in long term memory Three-Component Model Three…
Learning – process by which experience produces a relatively enduring change in an organism’s behaviour or capabilities Adapting to the Environment Behaviourists focus on how organisms learn, examining the processes by which the experience influences behaviour Ethology focuses on the functions of behaviour Adaptive significance – how behaviour influences an organism’s chances for survival Fixed…
Consciousness – our moment to moment awareness of ourselves and our environment Has various characteristics: Subjective and Private – reality and experience depend on the individual Dynamic – consciousness experiences are ever-changing and a continuous flow of mental activity Self-reflective and Central to Our Sense of Self – mind is aware of its own consciousness…
Sensation – the stimulus-detection process by which our sense organs respond to and translate environmental stimuli into nerve impulses that are sent to the brain Perception – active process of organizing the stimulus input and giving it meaning Sensory Processes Stimulus detection – absolute threshold designated as the lowest intensity at which a stimulus can…
Psychology = The scientific study of behaviour and the factors that influence it. Taking into account Biological, Individual and Environmental factors. Basic and Applied Science Two types of research: Basic research: Knowledge gained purely for its own sake. The goals are to describe how people behave and to identify factors that influence it. Research maybe…
