Outline Lecture 19 Individual Differences
1. Preamble: person vs. situation?
2. Individual Differences at Diff. Levels of Analysis (Mechanism, Development, Function)
- Differences require an explanation at all levels
3. Why Are There Any Differences? Why Aren’t People Identical?
4. Developmental Causes of Differences
- Malfunctions, pathologies, errors
- Facultative responses
5. Causes of Heritable Differences
–Low selection pressure:
–changing selective pressures:
–byproducts: leftovers of something else that is adaptive & heritable
–Frequency-dependent selection: payoffs for a trait are dependent on their prevalence
within the population
–cliff effect: if there is too much of a given trait in a population it can produce defects?
6. Psychopathy: a frequency-dependent strategy?
–What is a disorder?
–Psychopathy: deceitful, selfish, manipulative, impulsive, aggressive individuals with
little remorse or guilt
–“when a psychopath commits a violent act, they're not doing it because they're
malicious or evil. They're doing it because they don't give a damn.” (Hare, 2005)
–psychopaths account for:
–<1% of general population
–~23% of correctional population
–perhaps as much as 50% of repeat violent offenders
–parasitic lifestyle, glib superficial charm, pathological lying, manipulation
–The difference between “disorder” and “something we don’t like”
–many people consider psychopathy to be a pathology (disorder)
–think of it as a manipulation of genes (brokeness) during development
–but: we may be equating our dislike of their behaviour with “disorder”.
–There are many things that we dislike that are not disorders, could this be one
–what is a disorder? (not something that we dont like)
