    What is a Putative Genetic Basis?

    This is a term used when we assume a condition has a genetic basis because there's strong evidence that it's often passed down in families, but the exact genes involved are still unknown.

    Degree of genetic relatedness

    The study of people with varying degrees of genetic relatedness can help us understand the genetic basis of a particular trait. It is used to assess the extent to which a trait is influenced by genes or environment.

    General intelligence (g)

    The view that intelligence is a single, underlying factor that influences overall cognitive ability. It suggests that people who excel in one area of intelligence are likely to be good at other cognitive tasks.

    Dilution Model

    A model that explains how birth order can influence intelligence. It suggests that as the number of siblings increases, parents have fewer resources to allocate to each child, leading to less intellectual stimulation.

    Covariance of inheritance and environment

    The tendency for intelligent children to have intelligent parents who also provide enriched environments might lead to a biased view of intelligence. It becomes challenging to disentangle the influence of genetics from environment.

    Atheoretical view of intelligence

    It is difficult to establish a universal theory of intelligence to determine the content of IQ tests. The current approach is to measure intelligence based on what IQ tests measure.

    Study Notes

    Developmental Differences

    • Deviations from typical childhood development.
    • Lifelong, recurring in adulthood.
    • Include atypical cognitive, social, behavioral, language, or motor development.

    Causes of Developmental Differences

    • Genetic Factors:

      • Known genetic bases: Down syndrome, Fragile X syndrome, Williams syndrome, Rett's syndrome, Turner syndrome.
      • Putative genetic bases (suspected but not confirmed): Autism, ADHD, language disorders.
      • Genetic factors can be inherited or due to mutations.
    • Environmental Factors:

      • Access to therapy.
      • Home environment characteristics.
      • Nutrition.
      • Cerebral palsy (caused by pregnancy complications, birth trauma, or infections during pregnancy affecting brain development).

    Assessment and Diagnosis

    • Usually, parents initially consult a general practitioner (GP).
    • The GP refers the child to a specialist assessment.
    • Assessments are conducted by paediatricians or clinical psychologists.
    • Assessments include observation, history of difficulties, questionnaires from teachers and parents, and standardized assessments.

    Autism Spectrum Disorder (ASD)

    • Described in the 20th century by Kanner and Asperger.
    • Marked by differences in social interaction, communication, and restricted interests/repetitive behaviours.
    • Lifelong condition.
    • Characteristics:
      • Heterogeneous presentation (varied characteristics).
      • Found in individuals with high and low IQs.
      • 40% nonverbal; 60% verbal.
      • More common in boys.
    • Theories:
      • Theory of Mind (ToM): Difficulty understanding others' perspectives (e.g., unexpected transfer task, thinking too literally).
      • Weak Central Coherence: Limited understanding of the big picture; overly focused on details (e.g., embedded figures task).

    Attention Deficit Hyperactivity Disorder (ADHD)

    • Recognized in the early 1900s as hyperkinetic disorder.
    • Marked by attention difficulties (inattentiveness, distractibility), hyperactivity (difficulty sitting still), and impulsivity.
    • Characteristics:
      • More common in boys.
      • Some children improve; others maintain symptoms into adulthood.
      • High heritability.
      • Affected by environmental factors (e.g., diet, sugary drinks).
    • Theories:
      • Barkley: Underdeveloped executive functioning (goal functions, sense of time, flexible thinking, planning/prioritizing, working memory).
      • Sonuga-Barke: Difficulty with delayed gratification.

    Language Disorders

    • Prevalence: 7 per 100.
    • More common in boys.
    • Potentially related to underdeveloped Broca's and Wernicke's areas in the brain.

    Developmental Dyslexia

    • Difficulty with reading and spelling not explained by general poor ability.
    • Problems with syllable identification, rhyming, and sound discrimination.
    • Increased prevalence in English speakers compared to other languages (e.g., Italian, Japanese).
    • Has a genetic basis, but also affected by environmental factors (e.g., language transparency).

    Models of Disability

    • Medical Model: Impairments are problems needing medical treatments, regardless of causing pain or illness.
    • Social Model: Disability is caused by societal barriers, focusing on removing limitations to choices for people with disabilities.

    Neurodiversity

    • Recognizes differences as variations in human ability, not defects.
    • Celebrates diverse communication and self-expression.
    • Doesn't seek cures; emphasizes acceptance.
