AI Flashcards 1 Summary
What two factors contribute to abnormal behaviour?
Innate susceptibility for abnormal behaviour, and negative contextual factors that trigger that behaviour.
What are the three models used to define abnormal behaviour?
Cultural/social/ethical, statistical model, and medical model.
What is comorbidity?
Having multiple psychological/psychiatric disorders at the same time.
What is conduct disorder?
A psychiatric disorder characterized by severe antisocial and aggressive behavior, often emerging in childhood or adolescence.
What are some key symptoms of conduct disorder?
Aggression to people and animals, destruction of property, deceitfulness or theft, serious violation of rules, limited prosocial emotions.
What are some characteristics of ‘limited prosocial emotions’ in conduct disorder?
Lack of remorse or guilt, callous lack of empathy, unconcerned about performance, and shallow or deficient affect.
What is the relationship between conduct disorder and antisocial personality disorder?
Antisocial personality disorder is considered the adult form of conduct disorder.
What is the prevalence of conduct disorder in the population?
Approximately 7%.
What is the prevalence of psychopathy in the general population and incarcerated population?
1% of the general population and 30% of the incarcerated population.
Is psychopathy synonymous with extreme violence?
No, not all psychopaths commit violent acts, there are also ‘successful psychopaths’.
What is meant by the term ‘antisocial brain’?
It refers to the idea that some individuals may have differences in brain structure or function that predispose them to antisocial behaviour.
What is the connection between neurodevelopmental disorders and antisocial behaviour?
Antisocial behaviour can be linked to abnormal neurodevelopment that can affect brain structure, function, and connectivity, leading to deficits in behavior, cognition and emotion.
How do genetic and environmental factors interact in neurodevelopmental disorders?
Environmental factors often trigger underlying genetic predispositions. The interactions are specific to each developmental stage.
At what age is conduct disorder primarily diagnosed and what is the prognosis for individuals without psychopathic tendencies?
Primarily diagnosed between ages 5 and 20. Many individuals with CD symptoms outgrow these behaviors.
Is psychopathy treatable?
Psychopathy is notoriously challenging to treat effectively.
What are some prenatal and early life environmental factors that can impact brain development?
Maternal smoking, stress, substance abuse during pregnancy, and birth complications.
What are three types of gene-environment correlations?
Passive, active, and evocative.
Explain Passive gene-environment correlation.
Children inherit genetic predispositions from parents that also contribute to the environment that the parents create.
Explain Active gene-environment correlation.
Children actively seek out environments that match their genetic predispositions.
Explain Evocative gene-environment correlation.
A child’s genetic traits elicit negative responses from the environment.
How do genes relate to brain function and behaviour?
Genes code for proteins, which form neurons. Neurons form neuronal populations, which form neural systems, which drive behavior.
What is the role of the amygdala in the neurocognitive model of antisociality?
The amygdala acts as a salience detector, but it is often hyporesponsive to negative stimuli in antisocial individuals.
What are some characteristics of the amygdala in antisocial individuals?
It is often smaller, hyporesponsive to negative stimuli, and deprived of regulatory corticolimbic interactions.
What is the Paralimbic System Dysfunction Model of antisociality?
A model that suggests that antisocial behavior involves more than just the amygdala, and that there are a few areas in the brain that work differently. It also highlights how the brains of antisocial people compensate for certain deficits.
What is the significance of the basal lateral amygdala (BLA) and the centromedial amygdala (CMA) in humans and primates?
The larger BLA in humans and primates allows for complex socioemotional functions.
What are some of the problems with comparing large groups in studies of antisocial behaviour?
Classic approaches oversimplify, overlook variations, and do not account for the fact that conditions exist on a spectrum rather than as a clear distinction.
What are some of the difficulties in treating antisocial behavior?
The approach may have small effect size, and may have predictive limitations.
What is a strong predictor for committing crimes?
Having parents or close relatives who have committed crimes.
