The impact of emotional expressions on children’s trust judgments

Research on the development of selective trust has shown that young children do not indiscriminately trust all potential informants. They are likely to seek and endorse information from individuals who have proven competent or benign in the past. However, research on trust among adults raises the possibility that children might also be influenced by the emotions expressed by potential informants. In particular, they might trust individuals expressing more positive emotion. Indeed, young children’s trust in particular informants based on their past behaviour might be undermined by their currently expressed emotions. To examine this possibility, we tested the selective trust of fifty 4- and 5-year-olds in two steps. We first confirmed that children are likely to invest more trust in individuals expressing more positive emotion. We then showed that even if children have already formed an impression of two potential informants based on their behavioural record, their choices about whose claims to trust are markedly influenced by the degree of positive emotion currently expressed by the two informants. By implication, the facial emotions expressed by potential informants can undermine young children’s selective trust based on the behavioural record of those informants.     

学龄早期Asperger综合症儿童行为问题和注意、行为抑制功能研究

研究采用Achenbach儿童行为量表(父母用表)和注意、行为抑制及动作协调性行为任务对12名学龄早期的Asperger综合征儿童与29名在年龄及智力水平上与之匹配的正常儿童在行为问题、注意、行为抑制及动作协调等方面进行了比较.结果发现,在控制了年龄和智力因素后:1)Asperger综合征儿童的社会能力与正常儿童相比明显较差,同时常伴随有交往不良、社交退缩、焦虑、忧郁、强迫性、攻击性和多动等一系列行为问题;2)Asperger综合征儿童表现出一定的注意和行为抑制障碍,动作的协调性和灵活性较差.     

汉语致使句的形式处理

There are at least five kinds of causative constructions in Chinese, the constructions of the collocation of verbs and prepositional phrases, verb-copying constructions, “ba” constructions with an object ahead, verb-copying constructions with their complements, and pivotal constructions with commands. But the current type-logical grammar has no tools representing the meanings of causative constructions. It would be neither intuitive nor simple to describe these constructions by means of the current type-logical grammar. So we intend to improve the type-logical grammar by adding CAUSE as a logical constant, complementing the structure rules about the movement and addition or deletion of some components of causative constructions, assigning categories to Chinese nouns and prepositions; then we give an intuitive as well as simple analysis on these causative constructions. Based on this work we shall extend the multimodal system of type-logical grammar, increase structure postulates, make constraints on frame semantics, and then prove the soundness and completeness of that system.      

Dual temperamental risk factors for psychopathic personality: evidence from self-report and skin conductance

Psychopathy is a personality disorder consisting of dysfunctional affective interpersonal features (Factor 1) and impulsive-antisocial behavior (Factor 2) that exhibit differential associations with palmar skin conductance (SC) reactivity. The goal of this study was to determine whether the distinct SC reactivity observed in incarcerated psychopaths generalizes to university students who score high on personality dimensions hypothesized to be the risk factors for these psychopathy factors. Lilienfeld's Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) was used to compute scores on 2 factor-analytically derived dimensions that have been the focus of recent research in psychopathy. PPI-1 is hypothesized to relate to the low-fear temperamental risk factor, whereas PPI-2 is hypothesized to relate to regulatory dysfunction. SC reactivity was measured during tasks previously used in studies of diagnosed psychopaths. Results indicated that PPI-1 was associated with reduced SC during anticipation of an aversive noise and PPI-2 was associated with enhanced SC reactivity during presentation of a speech about one's faults. Additional analyses explored an 8-factor solution of the PPI and 3 temperament dimensions derived from factor analysis of several personality measures. Together, the SC results suggest that the Factor 1 pathway, best captured with refined assessments of behavioral fearlessness, related to reduced SC reactivity to an aversive noise-consistent with a weak defense system. The Factor 2 pathway, best captured by higher order dimensions reflecting externalizing, disinhibited forms of negative temperament, related to enhanced SC reactivity to a speech stressor-consistent with high stress reactivity.     

Walking and periventricular leukomalacia: locomotor characteristics and brain imaging (MRI)

The aim of the present study was to compare the walking abilities in infants with and without periventricular leukomalacia and to see whether the severity of the brain damage was related to locomotor outcome of the infants at 12 and 18 months. 47 newborns were included in the study based on white matter abnormalities on ultrasound. Magnetic resonance imaging (MRI) recordings during the neonatal period were used to identify and quantify the location and severity of the brain lesions. Locomotor outcome was assessed in terms of disability at 12 and 18 months. The quality of walking, including global and segmental gait parameters, was measured for the infants who could walk independently at 18 months and compared to a group of healthy control infants. The number of children who could walk was related to the extent of white matter abnormalities seen on the neonatal MRI, but the quality of walking was not.
