SPED 1020
Introduction Introduction
Reasons we are sometimes misled Pattern seeking Poor understanding of probability Memory is inherently flawed/ unreliable/ vulnerable to suggestion Power of belief and motivated reasoning Regardless of education/ intelligence/ background all can be fooled/ have irrational beliefs General knowledge does not protect from acceptance of misinformation Hard to distinguish pseudoscience from fact Questionable educational practices Facilitated communication: allow profoundly disabled to communicate through assisted typing Learning styles e.g. auditory, visual, kinesthetic ‘Digital natives’: younger gen have new technological capacities, developed fundamentally diff cognitive skills/ styles (e.g. multitasking) perceptual motor-programs (e.g. brain gym) claim that specific physical activity can improve a wide range of learning and related skills in children. Neuromyths in education (Dekker et al. (2012)) looked at prevalence and predictors of misconceptions amoung teachers on average, teachers believed 49% of the neuromyths despite general knowledge of the brain. Paranormal beliefs can people talk to the dead, connect to spirits? Health related homeopathy acupuncture natural remedies Reading: Hoggart, S., & Hutchinson, M. (1995) What types of pseudoscientific practices and beliefs are common to the areas of education, health and the paranormal? - In the 1970’s women were advocated to smoke to elevate morning sickness.
-
Sun beds were actively used and promoted in 1970’s.
How far can we rely on our cognitive abilities? - Not far as regardless of education, intelligence, or background – can all be fooled. What are some of the commonly held false beliefs held by the general population? - digital natives. Younger people have deep integration with internet technologies and develop fundamentally different cognitive skills. - power balance bands.
Cognitive basis 1 Example of weird beliefs Beliefs that if true would overturn current scientific worldview: Mediumship- the dead talking back Homeopathy Auras, graphology, rumpology (Bumps and lumps on buttock) Who believes weird things? All cultures, all societies Susceptibility traits – fantasy proneness ( unable to disassociate reality to not), hypnotic-suggestibility, dissociation The role of Cognition Our cognitive abilities consistently let us down We often see what we have not seen, hear what we have not heard and even recall events that never took place Pareidolia The tendency for incorrect perception of a stimulus as an object, pattern or meaning to the observer, thus perceive meaning in random stimuli Notably: Seeing shapes in clouds, seeing faces in inanimate objects or abstract patterns or hearing hidden messages in music. Often human being find meaning in paranormal context in random stimuli where none exists Preconceptions Perception is also influenced by context, environment and culture We see or hear what we expect (or are primed) to see or hear
The illusion of control The false belief that we have control over a random events
Poor understanding of probability Most people have a poor understanding of probability Doctors understand example (Gigerenzer, 2002) The concept of randomness Humans find the concept of randomness very hard to understand We find it difficult to recognise random patterns of coin tosses Randomness does not look random Coincidence – chance or evidence of the paranormal What are the chances of you having a prophetic (pre-cognitive) dream? Personal validation Subjective validation, sometimes called personal validation effect, is a cognitive bias by which a person will consider a statement or another piece of information to be correct if it has any personal meaning or significance to them. Barnum effect The Barnum effect in psychology refers to the gullibility of people when reading descriptions of themselves. Notably: You have a great need for other people to like and admire you. You have a great deal of unused capacity, which you have not turned to your advantage.
Summary Everybody is below average estimating probability Poor understanding of probabilities may contribute to belief in telepathy, precognition and psychic phenomena
Cognitive Bias 2 Anchoring Effects: Tendency of arbitrary baseline values to affect decisions Framing Effects We usually don’t have an inherent idea of value - it is “framed” by comparisons
Value attached to an item is influenced by irrelevant alternative choices We usually don’t have an inherent idea of value – it is “framed” by comparisons These can be and are manipulated to our choices Dunning-Kruger Effect (Kruger & Dunning, 2009) Those who are most incompetent tend to overestimate their social and intellectual ability. They misinterpret and their incompetence robs them of the metacognitive ability to recognise their errors. Celebrity “expert” phenomena = Jenny McCarthy – stating vaccines cause autism. How does memory work? Not the reliable data store that we assume Vulnerable to all kinds of misleading information, social influence, and individual differences No correlation between confidence and accuracy Misinformation effect Researchers have shown ways in which misinformation can manipulate a person’s memory Elizabeth Loftus – eye witness unreliability Our memory is more mailable than we realise Shopping mall effect Chasing memories- create false memories of seeing non-existent film footage of public events Doctored photographs – putting face on photo on hot air balloon ride Social influence and memory The Oklahoma Bombing Research shows that suggestion from a cowitness can influence memory of a witnessed event For example, Gabbert et al. (2011): – Videos of crime from unique perspectives – 71% of witnesses then reported they had seen events that were actually seen by other witnesses False Memory Syndrome In the late 1980s interest exploded in “repressed memory” Misguided therapists led patients to believe they had been abused creating false memories using suggestive techniques False Memory Societies were set up to offer “help” Many families ruined by accusations and innocent relatives sent to jail Confirmation Bias
Tendency to favour information that conforms with existing beliefs (or even an initial hypothesis) May involve Seeing what you are looking for Accepting information that is consistent with beliefs and dismissing information that is inconsistent Belief persistence How did we survive? Cognitive bias and oversensitive to patterns has survival value Cognitive biases are often heuristics (mental short cuts) that help us make quick decisions Two cognitive systems – fast and slow Summary: Cognitive biases don’t just affect us in the laboratory they affect everyday life Memory is not the reliable data bank that we assume and is susceptible to all kinds of misinformation and bias False memories of fictitious events can be created in the lab and everyday setting Confirmation bias may represent the most important of human cognitive biases There are MANY cognitive biases and logical fallacies that affect your perception, interpretation, reasoning and decisions....
