  • 1) Endophenotypes must be reliable and stable traits (reliability and stability).2) Endophenotypes must show evidence of genetic influences (heritability).3) Endophenotypes must be associated with the behavioural trait or disease of interest (phenotypic correlation).4) The association between endophenotype and trait of interest must derive partly from the same genetic source (genetic correlation).5) The association between the endophenotype and the trait of interest must be theoretically meaningful (causality). Gottesman & Gould, 2003 (see attached) developed more specific criteria for endophenotypes for psychopathology: 1. The endophenotype is associated with illness in the population.2. The endophenotype is heritable.3. The endophenotype is primarily state-independent (manifests in an individual whether or not illness is active).4. Within families, endophenotype and illness co-segregate.5. The endophenotype found in affected family members is found in nonaffected family members at a higher rate than in the general population. In terms of genetic influences, all of the above means that:-         Endophenotypes must show evidence of genetic influences (heritability). This doesn’t imply they should be 100% heritable, but there should be evidence that they are at least partly influenced by genes (e.g. based on findings from twin/adoption or family studies).-         The genetic influences on the endophenotype should (partly) overlap with the genetic influences on the condition of interest. In the current study, it is thought that the genetic influences on the (reduced) brain response to happy faces may tell us something about the genetic vulnerability for autism as a clinical condition. Once again, these genetic influences don’t have to have 100% penetrance.-         It is hoped that the endophenotype is a more reliable/stable trait that may be easier to measure than the complex behavioural phenotype of autism (see criteria 1 de Geus). If the endophenotype can be measured more reliably (i.e. less measurement error), and it is a less complex trait, the idea is that the endophenotype may be influenced by less genes, and you would thus increase the power to detect the genes involved. Of course the latter is a hypothesis: It may be that very many genes are involved in the brain response to happy faces. It may also be that this response is not so reliable after all (do we know anything about test-retest reliability of this measure?).-         Mikes important study gives a first clue that ‘response to happy faces’ could be a promising endophenotype for autism. Further studies (including reliability studies, and ideally some twin studies to explore the heritability of the endophenotype) should evaluate whether the measure truly passes the test for a good endophenotype. Of course the true litmus test would be a molecular genetic study using the measure.

According to the mental-state reasoning model of suggestibility, 2 components of theory of mind mediate reductions in suggestibility across the preschool years. The authors examined whether theory-of-mind performance may be legitimately separated into 2 components and explored the memory processes underlying the associations between theory of mind and suggestibility, independent of verbal ability. Children 3 to 6 years old completed 6 theory-of-mind tasks and a postevent misinformation procedure. Contrary to the model's prediction, a single latent theory-of-mind factor emerged, suggesting a single-component rather than a dual-component conceptualization of theory-of-mind performance. This factor provided statistical justification for computing a single composite theory-of-mind score. Improvements in theory of mind predicted reductions in suggestibility, independent of verbal ability (Study 1, n = 72). Furthermore, once attribution biases were controlled (Study 2, n = 45), there was also a positive relationship between theory of mind and source memory, but not recognition performance. The findings suggest a substantial, and possibly causal, association between theory-of-mind development and resistance to suggestion, driven specifically by improvements in source monitoring., (C) 2008 by the American Psychological Association Bruck, M., K. London, et al. (2007). "Autobiographical memory and suggestibility in children with autism spectrum disorder." Dev.Psychopathol.19(1): 73-95. Two paradigms were developed to examine autobiographical memory (ABM) and suggestibility in children with autism spectrum disorder (ASD). Children with ASD (N = 30) and typically developing chronological age-matched children (N = 38) ranging in age from 5 to 10 years were administered an ABM questionnaire. Children were asked about details of current and past personally experienced events. Children also participated in a staged event, and later were provided with true and false reminders about that event. Later, children again were interviewed about the staged event. The results from both paradigms revealed that children with ASD showed poorer ABM compared to controls. Generally, their ABM was marked by errors of omission rather than by errors of commission, and memory was particularly poor for early-life events. In addition, they were as suggestible as the typically developing children. The results are discussed in terms of applied and theoretical implications

  • 2. Proposed DSM-V criteria for ASD
    Must meet criteria A, B, C, and D:
     
    A.    Persistent deficits in social communication and social interaction across contexts, not accounted for by general developmental delays, and manifest by all 3 of the following:
    1.     Deficits in social-emotional reciprocity; ranging from abnormal social approach and failure of normal back and forth conversation through reduced sharing of interests, emotions, and affect and response to total lack of initiation of social interaction,
    2.     Deficits in nonverbal communicative behaviors used for social interaction; ranging from poorly integrated- verbal and nonverbal communication, through abnormalities in eye contact and body-language, or deficits in understanding and use of nonverbal communication, to total lack of facial expression or gestures.
    3.     Deficits in developing and maintaining relationships, appropriate to developmental level (beyond those with caregivers); ranging from difficulties adjusting behavior to suit different social contexts through difficulties in sharing imaginative play and  in making friends  to an apparent absence of interest in people

    Merging of AS with ASD and disintegrative disorder
    Lamented by Aspies
    Disintegrative disorder is progressive

    Possible increase in age criterion
    May raise later confusion with schizophrenia (again)
    Disappearance of the triad
    Lamented by Wing, Gould, and Gillberg(Research Autism paper) because of Falck-Ytter
    who argue that social interaction and
    But still mixing primary impaired in social interaction with its effects in social relationship
    Verbal communication disappears

    2.     Excessive adherence to routines, ritualized patterns of verbal or nonverbal behavior, or excessive resistance to change; (such as motoric rituals, insistence on same route or food, repetitive questioning or extreme distress at small changes).
    3.     Highly restricted, fixated interests that are abnormal in intensity or focus; (such as strong attachment to or preoccupation with unusual objects, excessively circumscribed or perseverative interests).
    4.     Hyper-or hypo-reactivity to sensory input or unusual interest in sensory aspects of environment; (such as apparent indifference to pain/heat/cold, adverse response to specific sounds or textures, excessive smelling or touching of objects, fascination with lights or spinning objects).
    C.    Symptoms must be present in early childhood (but may not become fully manifest until social demands exceed limited capacities)
    D.     Symptoms together limit and impair everyday functioning.

  • 23. CONCLUSIONS: This study provides preliminary evidence of impaired neural connectivity in the corpus callosum/cingulum and temporal lobes involving the inferior longitudinal fasciculus/inferior fronto-occipital fasciculus and superior longitudinal fasciculus in ASDs. These findings provide preliminary support for aberrant neural connectivity between the amygdala, fusiform face area, and superior temporal sulcus-temporal lobe structures critical for normal social perception and cognition.

  • 26. “Attributing behavioral outcomes correctly to oneself or to other agents is essential for all productive social exchange. We approach this issue in high-functioning males with autism spectrum disorder (ASD) using two separate fMRI paradigms. First, using a visual imagery task, we extract a basis set for responses along the cingulate cortex of control subjects that reveals an agent-specific eigenvector (self eigenmode) associated with imagining oneself executing a specific motor act. Second, we show that the same self eigenmode arises during one's own decision (the self phase) in an interpersonal exchange game (iterated trust game).
    Third, using this exchange game, we show that ASD males exhibit a severely diminished cingulate self response when playing the game with a human partner. This diminishment covaries parametrically with their behaviorally assessed symptom severity, suggesting its value as an objective endophenotype.
    These findings may provide a quantitative assessment tool for high-functioning ASD.”

    Synchrony
    Armies, churches, organizations, and communities often engage in activities for example, marching, singing, and dancing that lead group members to act in synchrony with each other.….Across three experiments,
    people acting in synchrony with others cooperated more in subsequent group economic exercises, even in situations requiring personal sacrifice. Our results also showed that positive emotions need not be generated for synchrony to foster cooperation. In total, the results suggest that acting in synchrony with others can increase cooperation by strengthening social attachment among group members

    Although both groups can appear uncaring, our findings suggest that the affective/information processing correlates of psychopathic tendencies and ASD are quite different. Psychopathic tendencies are associated with difficulties in resonating with other people’s distress, whereas ASD is characterised by difficulties in knowing what other people think

    For pupils with SEN or no identified SEN, the risk of being bullied declines by approximately 9 per cent each chronological year.
    Pupils bullied in Year 9 (13-14-year-olds) are much more likely to drop out of school at Year 11 (15-16-year-olds) than those who were not bullied. This trend is even more pronounced for pupils with SEN.

    How many people with ASD have been abused?
    Difficult to establish but possibly a significant no.
    Suspicion should be raised by deterioration in behaviour, sexual disinhibition, regression

    People with ASD may feel that sexual favours are a fair exchange for social contact

    Increased perspective taking reduces aggression
    (Richardson et al, 1994,Empathy as a cognitive inhibitor of interpersonal aggression. Aggressive Behaviour, 20, 276-289)
    Secondary inhibition (Feshbach and Feshbach, 1969) results from seeing the fear (Blair) or disgust (Nichol) in the other and acts to mitigate aggression
    (de Paul et al, 2006, Aggression inhibition in high- and low-risk subjects for child physical abuse: effects of a child’s hostile intent and the presence of mitigating information, Aggressive Behaviour, 32, 216-230

  • 84. Cognitive and affective empathy
    Fifty-two boys (25 aggressive and 27 non-aggressive) were compared for levels of aggression and for cognitive and affective empathy as expressed during a group interview involving bibliotherapy.
    Aggressive boys showed half the level of affective empathy as non-aggressive boys, although the groups did not differ in cognitive empathy
    Study of cognitive and affective empathy in aggressive boys(Schechtman, Z. (2002) Cognitive and affective empathy in aggressive boys: implications for counselling. International Journal for the Advancement of Counselling, 24, 211-.
    Although both groups can appear uncaring, our findings suggest that the affective/information processing correlates of psychopathic tendencies and ASD are quite different. Psychopathic tendencies are associated with difficulties in resonating with other people’s distress, whereas ASD is characterised by difficulties in knowing what other people think
    JONES, A. P., HAPPÉ, F. G. E., GILBERT, F., BURNETT, S. & VIDING, E. 2010. Feeling, caring, knowing: different types of empathy deficit in boys with psychopathic tendencies and autism spectrum disorder. Journal of Child Psychology and Psychiatry, 51, 1188-1197
  • 85. Does empathy lead to violence, either through an increase in aggression or a reduction in violence inhibition?
    Correlational studies link low empathy and increased aggression
    Empathy ‘mitigates aggression’ (Bjorkqvist, Osterman, & Kaukiainen, 2000)
    But aggressive two year-olds may actually show more empathy than non-aggressive two years olds (Gill & Calkins, 2003)
