- Cognitive Processes- Fundamentals.
- Implacable experimenter
- Situation in experimental research in which experimental behaviour is uninfluenced by participant behaviour.
- Paradigm specificity
- Occurs when findings within given experiments or paradigms are not obtained even when apparently very similar tasks are used.
- Ecological Validity
- Applicability of findings of laboratory studies to everyday settings.
- Bottom-up Processing
- Starting with the stimulus and moving through the functions until receiving a response. Stimulus, data and perceptually driven.
- Reductionism
- Approach to perception. BU breaks down process into basic elements.
- Top-down Processing
- Process directly affected by past experiences and expectations. Conceptually, memory and expectation driven.
- Serial Processing
- Only one process occurs at one time. The current process is completed before the next one starts.
- Parallel Processing
- More than one process occurs at a time. Nearly all processing is done parallel especially when skilled or highly practiced in that area.
- 5 senses
- Visual, Auditory, Olfaction, Taste and Touch.
- Gibson
- Founder of processing debate.
- visual perception.
- suggested solely understood by environmental stimulus.
- Sensory Information
- Experience this about the world around us such as light levels from environment.
- Signals brought to retina.
- Transduction transforms signals into electrical impulses. They travel along visual pathways to the brain where they enter visual cortex and form experiences.
- Types of data
- Qualitative
- Self report, cases studies and natural observations.
- Quantative
- Experiments, Neuroscience, computer stimulations.
- Qualitative
- Approaches
- Experimental Psychology
- Changing rule to try change behaviour. Manipulation of variable. Normally conducted on healthy adults in lab.
- Cognitive Neuroscience
- Basis of neural behaviour and parts of brain responsible. Use methods such as fMRI and EEG. Atypical participants, expensive and requires specialist training.
- Experimental Psychology
- Experiments
- Ecological validity. Variables and measure behaviour. Healthy in lab. Reaction time and accuracy. 'Stroop Test'
- Computational Modelling
- Input/Output. Does not collect data on humans. Stimulates human behaviour.
- Building Artificial intelligence and psychology. Based analogy between mind and brain. Used computer program model to stimulate human behaviour based on input and output approach.
- Prosopagnosia
- Known as face blindness. neuro disorder. able to perceive not recognise. BU functional, TD impaired.
- Implacable experimenter
