  1. RESEARCH METHODS Recap

  2. Definition?

  3. Mental Processes Thoughts Feelings These are personal, or subjective and cannot be observed directly

  4. Behaviour Externally expressed action made by a living person that can be directly observed

  5. Research Methods A particular way of conducting a research study to collect accurate and reliable information about behaviour and mental processes

  6. Experimental research An experiment is used to test a cause and effect relationship between variables under control conditions

  7. What is a variable? Definition: A variable is any characteristic or value that can be changed or manipulated. In psychology experiments, researchers utilize variables to determine if making changes to one thing can result in changes to something else. For example, researchers might look at whether the amount of sleep students get the night before an exam impacts their performance on the test. In this example, the amount of sleep and performance on the test are the two variables of interest.

  8. Steps in psychological research • Identification of the research problem • Construct Hypothesis • Design the method • Collection of data. • Analysis of the data. • Interpretation of the data • Reporting of the research method.

  9. Dependent variable (DV) Independent variable (IV) • Variable that is systematically manipulated, changed or varied in some way by the research in order to assess its effect on the participants’ responses. • How the variable is manipulated is decided and planned before the experiment begins • Shows any effects of the independent variable. • The aspect of a participants behaviour or experience that is observed or measured and is expected to change as a result of the manipulation of the IV

  11. States of ConsciousnessChapter 2 Things never were “the way they used to be.” Things will never be “the way it’s going to be someday.” Things are always just the way they are for the time being. And the time is always in motion. Alexander Evangeli Xenopouloudakis

  12. What is consciousness? • Intro • Awareness of one’s own mental activity • Personal • Can be selective • Consciousness is continuous and ever-changing

  13. A state of consciousness is characterised by.. • Level of awareness of internal and external stimuli • varing levels of awareness of our internal state and external events • Two broad categories: • Normal Waking Consciousness (NWC) • Altered States of Consciousness (ASC)

  14. How to measure? • Consciousness is referred to as a psychological construct. • A psychological construct cannot be measured or observed and is simply inferred from information gathered from the individual or behaviour demonstrated or from physiological measures. Determining state of consciousness Individual information provided Behaviour demonstrated Physiological measures e.g. self reports e.g. experimental research EEG, HR, BT, GSR

  15. Introducing consciousness • Consciousness has many variations—there are lots of different levels of awareness as well as variations in the way individuals experience them. • There is no precise location for each state of consciousness—consciousness should rather be viewed as a continuum. • Despite the lack of definition between these states, there are qualities that distinguish between different states of consciousness.

  16. Qualities that distinguish the different states of consciousness… • Level of awareness • The content of consciousness • Use of controlled or automatic processes to perform tasks • Perceptual abilities • Emotional awareness • Self-control • Experience of time

  18. Normal waking consciousness Attention is often used to measure consciousness. It involves focusing on either external or internal stimuli. • Selective attention requires focusing on specific stimuli and ignoring others. • Divided attention is when we divide our attention to focus on multiple things. When could having divided attention become a problem? When could it be advantageous? Source: Stockbyte

  19. Normal Waking Consciousness • Levels of Awareness • Controlled processes • Automatic Processes • Levels of Attention • Limitation of cognitive content • Memory • Experience of time and sensation

  20. Normal waking consciousness (NWC) Content limitations: • Content is more organised and logical than during altered states of consciousness. • Also more restricted as we are able to block out unwanted content. Controlled and automatic processes: • Controlled processes require active concentration on the task at hand. Only one controlled process can be undertaken at a time. • Automatic processes require little mental effort. These processes can be performed with divided attention.

  21. Stroop Effect…. • Stroop effect demonstrates the effects of automatic processing. • American psychologist John Ridley Stroop (1935) found that participants were slower to perform a task and made more errors when they were required to visually process visually “incongruent”(conflicting or mismatching information) • Lets have a go..

  22. Stroop effect ..research methods • In the three experiment's Stroop used a different group of research participants and a repeated measures design for each of the three experiments… • What is a repeated measures design?

  23. Normal waking consciousness (NWC) Which condition of the Stroop Effect demonstrates an automatic process and a controlled process?

  24. Altered states of consciousness.. Any state of consciousness that deviates from normal waking consciousness, in terms of marked differences in the level of awareness, perceptions, memoires, thinking, emotions behaviours and sense of time, place and self control..

  25. Altered states of consciousness Disorientations of perception and cognition • Altered states of consciousness affect the senses in one of two ways: • Enhances the experiences of external stimuli (e.g. a drug induced state may result in more sensations experienced more vividly). • Dulls the experiences of external stimuli (e.g. meditation may elevate your pain threshold). • Cognitive functioning is often impaired, is illogical and non-sequential and may result in individuals being unable to remember experiences under this state.

  26. Altered states of consciousness Time orientation • Time passes at different speeds under altered states of consciousness • If in a meditative state, time may be perceived at a slower rate. Give an example of an altered state of consciousness when time would pass more slowly? What about when time would pass more rapidly? Source: Getty

  27. Altered states of consciousness Changes in emotional awareness • Some altered states of consciousness affect our feelings, which may result in uncharacteristic or unpredictable responses: • During an alcohol induced state, some people become more emotional. • In a drug induced state an individual may alternate between euphoria or violence without any triggering events. • Some states result in individuals feeling less emotion e.g. duringmeditation.

  28. Altered states of consciousness Changes in self control • Changes in self-control are often evident in altered states of consciousness. Individuals may have trouble coordinating and controlling their movements, as well as their emotions and responses: • During an alcohol induced state individuals often appear uncoordinated and may also behave in a manner that is incongruent with their normal waking consciousness behaviour. • When under a state of hypnosis, people may be more susceptible to suggestion, but hypnosis can also help individuals gain more self control over addictions or pain management.

  29. Daydreaming as ASC • Imaginary scenes & events that occur while awake • When do they happen? • Possible functions: • Mental rehearsal • Mental arousal when bored • Problem solving (practical & creative) • Pleasure
