The ‘Fractionable Autism Triad’: A Review of Evidence from Behavioural,Genetic, Cognitive and Neural Research 总被引:1,自引:0,他引:1
Autism is diagnosed on the basis of a triad of impairments in social interaction, communication, and flexible imaginative
functions (with restricted and repetitive behaviors and interests; RRBIs). There has been a strong presumption that these
different features of the syndrome are strongly intertwined and proceed from a common cause at the genetic, cognitive and
neural levels. In this review we examine evidence for an alternative approach, considering the triad as largely ‘fractionable’.
We present evidence from our own twin studies, and review relevant literature on autism and autistic-like traits in other
groups. We suggest that largely independent genes may operate on social skills/impairments, communication abilities, and RRBIs,
requiring a change in molecular-genetic research approaches. At the cognitive level, we suggest that satisfactory accounts
exist for each of the triad domains, but no single unitary account can explain both social and nonsocial features of autism.
We discuss the implications of the fractionable-triad approach for both diagnosis and future research directions. 相似文献

A man with multiple disabilities using a head‐turning response to reduce the effects of his drooling
Giulio E. Lancioni Nirbhay N. Singh Mark F. O'Reilly Jeff Sigafoos Doretta Oliva Francesca Campodonico Jop Groeneweg 《Behavioral Interventions》2008,23(4):285-290
A man with multiple disabilities was taught to perform a head‐turning response to activate optic sensors embedded in a small spongy structure at his shoulder and produce preferred stimuli. By touching the spongy structure with chin and mouth (i.e., to activate the sensors), the man would clean these areas thus curbing the effects of his drooling. Data showed that the man increased the frequency of his head‐turning responses and reduced drooling effects (chin wetness) through the intervention and a 3‐month follow‐up. Forty university students, who were involved in a social validation assessment, indicated that the intervention was suitable and enjoyable to the man, had a social/educational function, and represented an approach that they supported.

Conjunctive probabilistic reasoning has been studied at different ages to ascertain whether the conjunction fallacy is due to a task demand misinterpretation. Such a misinterpretation might occur because a task that requires a comparison between a superordinate class A and a subordinate class A&B is mistakenly interpreted as requiring a comparison between the two complementary subordinate classes of A (i.e., A&B and A¬B). Children (7- and 10-year-olds) and adults were required to make conjunctive probability judgments about problems for which explicit objective probabilities were provided. The total number of A items was kept constant and the frequencies of the A&B and of the A¬B items varied across problems. When the number of A&B items was smaller than the number of A¬B items, the frequency of congruent responses increased with age. When the number of A&B items was greater or equal to that of the A¬B items, the frequency of correct answers decreased. (PsycINFO Database Record (c) 2008 APA, all rights reserved). 相似文献

Humans represent numbers on a mental number line with smaller numbers on the left and larger numbers on the right side. A left‐to‐right oriented spatial–numerical association, (SNA), has been demonstrated in animals and infants. However, the possibility that SNA is learnt by early exposure to caregivers’ directional biases is still open. We conducted two experiments: in Experiment 1, we tested whether SNA is present at birth and in Experiment 2, we studied whether it depends on the relative rather than the absolute magnitude of numerousness. Fifty‐five‐hour‐old newborns, once habituated to a number (12), spontaneously associated a smaller number (4) with the left and a larger number (36) with the right side (Experiment 1). SNA in neonates is not absolute but relative. The same number (12) was associated with the left side rather than the right side whenever the previously experienced number was larger (36) rather than smaller (4) (Experiment 2). Control on continuous physical variables showed that the effect is specific of discrete magnitudes. These results constitute strong evidence that in our species SNA originates from pre‐linguistic and biological precursors in the brain. 相似文献

Taking a psychodynamic perspective, the present exploratory study proposes an integrated approach to explore the forced migratory experience, focusing simultaneously on mental health risk and protective factors and on the quality of the subjective experience of migration. We aimed to evaluate trauma and protective factors and to explore in-depth representations and meanings asylum seekers hosted in Italy attribute to their experiences. Levels of trauma and resilience were first evaluated for twenty asylum seekers hosted in two Reception Centres; then, in-depth interviews were administered. Six out of twenty participants presented with symptoms of trauma and all presented with moderately high resilience levels. The interviews were analysed using a quality-quantitative methodology via T-Lab software, and showed four thematic clusters: A godforsaken place; From death to life across the sea; Memories from the past; Searching for a land of care. In line with the identity fracture highlighted in psychodynamic literature, our results show a breakdown between the deeper and original aspects of participants’ identity and their new cultural identity as migrants, which has many social components. Reflections on the implications of the study will be outlined. 相似文献

In accordance with the Self‐determination Theory (SDT), six dimensions of parenting (autonomy support vs. psychological control, structure vs. chaos, warmth vs. rejection) could be defined in their relation to adolescents’ adjustment. However, the mechanisms of these relations need to be further deepened. In accordance with SDT, the aims of this study were: (1) to examine the relationships between the six dimensions of parenting and the three psychological basic needs; (2) to examine the mediation role of basic psychological needs in the relation between parental practices, and positive and negative outcomes in a sample of Italian adolescents. In a sample of 342 adolescents, results suggest that supportive parenting practice (autonomy support, structure, and warmth) promotes need fulfillment and adjustment, while thwarting parenting practice (psychological control, chaos, and rejection) reduces need fulfillment and adjustment. Furthermore, the three psychological basic needs (autonomy, competence and relatedness) mediate the relations between parenting and adolescents’ adjustment. These findings highlight the role of parenting in adolescents’ adjustment and in line with SDT provide evidence of the dynamic between parenting, psychological needs and adjustment. 相似文献

Viewing a face (especially one's own face) being touched enhances tactile perception on the face 总被引:1,自引:0,他引:1
Observing touch on another person's body activates brain regions involved in tactile perception, even when the observer's body is not directly stimulated. Previous work has shown that in some synaesthetes, this effect induces a sensation of being touched. The present study shows that if perceptual thresholds are experimentally manipulated, viewing touch can modulate tactile experience in nonsynaesthetes as well. When observers saw a face being touched by hands, rather than a face being merely approached by hands, they demonstrated enhanced detection of subthreshold tactile stimuli on their own faces. This effect was specific to observing touch on a body part, and was not found for touch on a nonbodily stimulus, namely, a picture of a house. In addition, the effect was stronger when subjects viewed their own faces rather than another person's face. Thus, observing touch can activate the tactile system, and if perceptual thresholds are manipulated, such activation can result in a behavioral effect in nonsynaesthetes. The effect is maximum if the observed body matches the observer's body. 相似文献

Immersiveness and physiological arousal within panoramic video-based virtual reality. 总被引:1,自引:0,他引:1

In this paper, we discuss findings from a study that used panoramic video-based virtual environments (PVVEs) to induce self-reported anger. The study assessed "immersiveness" and physiological correlates of anger arousal (i.e., heart rate, blood pressure, galvanic skin response [GSR], respiration, and skin temperature). Results indicate that over time, panoramic video-based virtual scenarios can be, at the very least, physiologically arousing. Further, it can be affirmed from the results that hypnotizability, as defined by the applied measures, interacts with group on physiological arousal measures. Hence, physiological arousal appeared to be moderated by participant hypnotizability and absorption levels. 相似文献

The present study assessed the possibility of promoting pre-ambulatory foot–leg movements in children with multiple disabilities
by motivating their action through contingent stimulation combined with a support device. Two children aged 10 and 8 years
participated. Microswitch technology (i.e., pressure sensors under the shoes or optic sensors at the front–inner side of the
shoes) served for detecting the foot–leg movements and providing contingent stimulation on their occurrence. Sensor activation
produced 5 s of stimulation during intervention. Data showed that both children had significant increases in foot–leg movements
during the intervention phases. Implications of the data in terms of skill acquisition and further intervention prospects
are discussed. 相似文献
