Cyberbullying Bullying that occurs online, via the internet. Featured Study: Bullying in Canadian Schoolyards Method Using a naturalist method, Pepler & Craig were able to obverse natural bullying episodes on the school playground. They observed ~35 teacher-nominated aggressive & ~30 teacher-nominated socially competent children, who were an average of 9.9 years old. They also installed microphones on target children who picked up audio of conversations. Results Half (50%) of all bullying episod

The Scientific Approach to Behaviour Goals of the Scientific Enterprise 3 sets of interrelated goals Measurement & Description Measure phenomenon under study Goal is to develop measurement techniques that make it possible to describe behaviour, clear and precisely Understanding & Prediction Able to explain the reason for the occurrence of the events Hypothesis - Tentative statement about the relationship between 2 variables Variables - Measurable co

DEFINITIONS Hypothesis - An unconfirmed statement of prediction relating two or more variables. Variables - Measurable conditions, events, characteristics, or behaviour that are controlled (independent variable) or observed (dependent variable) in a study. Theory - Set of interrelated ideas used to explain a set of observations. A good theory will generate a host of testable hypotheses. Empirical - A method of research that can be verified by observation and experiment. THE SCIENTIFIC APPROACH T

Nervous System, Brain Researching Methods, Parts of the Brain, Evolutionary Bases Communication in the Nervous System What is the Nervous System? A living tissue composed of cells. Cells in nervous systems receive, integrate & transmit information. 2 Major Categories of Cells in the Nervous System Neurons: Individual cells in the nervous system that receive, integrate & transmit information. Basic link that permit communication in the nervous system. Vast majority communicate only with other neu

The Anatomy of the Nervous System Neurons - Individual cells in the nervous system Receive, integrate, and transmit information Glial Cells - Found throughout the nervous system Provide various types of support for Neurons "Glue" in Greek Cerebrospinal Fluid - Cushions the brain during an impact Forms the blood-brain barrier that prevents foreign material (drugs and viruses) Contributes to the immune system of the brain Neurons Synapse - Junction where information is transmitted from one Neuron

Threshold, Signal-Detection Theory, Senses What is Synesthesia? Synesthesia is a condition where perceptual or cognitive activities trigger other experiences. One sense is coupled/paired with another (for example, seeing red every time you hear the word ‘train’ OR listening to music can lead to an emotional response known as emotional synesthesia). Do we all have a little synesthesia? We all experience certain events or feelings when we perceive. What is Sensation? What is Perception? Sensation

Stimulus - Anything that stimulates the senses Stimuli - Produces response Sensation - The stimulation of sense organs Absorption of energy (light/sound waves) by sensory organs (ears/eyes) Perception - The selection, organization, interpretation, and sensory input Organizing, translating sensory input into something meaningful Synethesia - Perceptual or cognitive activities (listening to music, reading) trigger exceptional experiences (colour, taste) Psychophysics - Basic Concepts and Issues

Somniloquy - Is talking while sleeping. It’s like a soliloquy except done in someone’s slumber. Narcolepsy - Is a sleep disorder where people will randomly go to sleep during the day. The Nature of Consciousness Consciousness Is the awareness (with varying degrees) of internal & external stimuli. Our thoughts flow & fluctuate; William James named this flow the stream of consciousness. Variations in Awareness & Control Attention & consciousness are closely related but not identical.

Learning Learning is any relatively durable change in behaviour or knowledge that is due to experience. Animals can learn & the principles that explain learned responses in animals explain human behaviour as well. Phobias Phobias are irrational fears of objects or situations, often a result of classical conditioning. Phobias are a type of anxiety disorder (10% of Canadian population suffer from these). Agoraphobia Fear of being in public places difficult to escape from or in which it might be

Learning - Any relatively durable change in behaviour or knowledge that is due to experience Superstitions are often the result of obtaining rewards after engaging in some behaviour Conditioning - Learning connections between events that occur in an organism's environment Classical Conditioning Phobia - Irrational fears of specific objects or situations Classical Conditioning - Type of learning in which a stimulus acquires the capacity to evoke a response that was originally caused by another s

Episodic - Memory for personal events (like when to eat, or events in your life). Semantic - Memory for general information (like facts). This phenomena is represented by patient K.C., who was treated by Endel Tulving at the University of Toronto. Tulving found K.C. had perfect semantic vision but no episodic vision, after a motorcycle acci

Key Concepts in Psychological Testing Psychological Test It is a standardized measure of a sample (potentially not representative) of a person’s behaviour. These tests are measurement instruments that measure the individual differences that exist among people in abilities, aptitudes, interests & aspects of personality.

It’s a reasonably orderly, cumulative process that includes the biological & behavioural changes that take place as people age.

D. Ewen Cameron Was the founder & director of the Allan Memorial Institute in Montreal. In the late 1950s & early 1960s, he was engaged in CIA-funded research designed to examine brainwashing & thought-control. In Cameron’s facility, patients were exposed to experimental techniques that included extended drug-induced periods of sleep (sometimes for weeks at a time), massive electroconvulsive (shock) therapy regimens, sensory deprivation, hours upon hours of tape-recorded messages, psychic drivin
