Two types of behaviours shown in children - those reflecting social impairment and nonsocial obsessive repetitive behaviours - are central to defining and diagnosing autism spectrum disorders (ASDs). Parent and teacher data on social and nonsocial behaviours were obtained from a community sample of >3000 7-year-old twin pairs. Social and nonsocial behaviours were only modestly correlated, and it was found that some individuals had extreme scores on either social or nonsocial scales but not both. Genetic model-fitting showed that social and nonsocial behaviours are both highly heritable, but their genetic overlap is modest, with most of the genetic influence being specific to either social or nonsocial behaviours. Considering these behaviours separately might help clarify gene-brain-behaviour pathways in future research. 相似文献

Current models of prospective timing hypothesize that estimated duration is influenced either by the attentional load or by the short-term memory requirements of a concurrent nontemporal task. In the present study, we addressed this issue with four dual-task experiments. In Exp. 1, the effect of memory load on both reaction time and temporal production was proportional to the number of items of a visuospatial pattern to hold in memory. In Exps. 2, 3, and 4, a temporal production task was combined with two visual search tasks involving either pre-attentive or attentional processing. Visual tasks interfered with temporal production: produced intervals were lengthened proportionally to the display size. In contrast, reaction times increased with display size only when a serial, effortful search was required. It appears that memory and perceptual set size, rather than nonspecific attentional or short-term memory load, can influence prospective timing. 相似文献

Six experiments are reported that were aimed at demonstrating the presence in newborns of a perceptual dominance of global over local visual information in hierarchical patterns, similar to that observed in adults (D. Navon, 1977, 1981). The first four experiments showed that, even though both levels of visual information were detectable by the newborn (Experiments 1A and 1B), global cues enjoyed some advantage over local cues (Experiments 2 and 3). Experiments 4A and 4B demonstrated that the global bias was strictly dependent on the low spatial frequency content of the stimuli and vanished after selective removal of low spatial frequencies. The results are interpreted as suggesting parallels between newborns' visual processing and processing later in development. 相似文献

People often make judgments about the ethicality of others’ behaviors and then decide how harshly to punish such behaviors. When they make these judgments and decisions, sometimes the victims of the unethical behavior are identifiable, and sometimes they are not. In addition, in our uncertain world, sometimes an unethical action causes harm, and sometimes it does not. We argue that a rational assessment of ethicality should not depend on the identifiability of the victim of wrongdoing or the actual harm caused if the judge and the decision maker have the same information. Yet in five laboratory studies, we show that these factors have a systematic effect on how people judge the ethicality of the perpetrator of an unethical action. Our studies show that people judge behavior as more unethical when: (1) identifiable vs. unidentifiable victims are involved and (2) the behavior leads to a negative rather than a positive outcome. We also find that people’s willingness to punish wrongdoers is consistent with their judgments, and we offer preliminary evidence on how to reduce these biases. 相似文献

In this paper we introduce and compare four different syntactic methods for generating sequent calculi for the main systems
of modal logic: the multiple sequents method, the higher-arity sequents method, the tree-hypersequents method and the display
method. More precisely we show how the first three methods can all be translated in the fourth one. This result sheds new
light on these generalisations of the sequent calculus and raises issues that will be examined in the last section. 相似文献

Two experiments were conducted to explore the extent to which individuals with Autism Spectrum Disorder (ASD), as well as young typically developing (TD) children, are explicitly aware of their own and others’ intentions. In Experiment 1, participants with ASD were significantly less likely than age‐ and ability‐matched comparison participants to correctly recognize their own knee‐jerk reflex movements as unintentional. Performance on this knee‐jerk task was associated with performance on measures of false belief understanding, independent of age and verbal ability, in both participants with ASD and TD children. In Experiment 2, participants with ASD were significantly less able than comparison participants to correctly recognize their own or another person’s mistaken actions as unintended, in a ‘Transparent Intentions’ task ( Russell & Hill, 2001 ; Russell, Hill & Franco, 2001 ). Performance on aspects of the Transparent Intentions task was associated with performance on measures of false belief understanding, independent of age and verbal ability, in both participants with ASD and TD children. This study suggests that individuals with ASD have a diminished awareness of their own and others’ intentions and that this diminution is associated with other impairments in theory of mind. 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

Between 10 and 24 months of age, children progress from communicating through conventional signals to communicating through symbols in a variety of situations. The present study investigates this transition analysing mother–child communication frames and the child's communicative acts, and tracing the developmental changes in both frames and communicative acts. Four children (2 girls, 2 boys) and their mothers were observed longitudinally and extensively, from 10 to 24 months of age, using a multiple case‐study method. Through the detailed investigation of these single cases, clear developmental rajectories were found, showing that conventional frames and representational gestures ‘bridge’ the transition from attentional to symbolic communication. There were significant differences between dyads and children in the developmental trajectories for several frames and communicative acts. The results not only confirm previous findings on the development of verbal and gestural communication, but provide new insights into the transition to symbolic communication in the second year of life, first because of the use of frame analysis and second because of a focus on individual trajectories in development.
