Mandarin requires neither determiners nor morphological inflections, which casts doubt on Mandarin‐speaking children's ability to use function words as a syntactic bootstrapping tool to identify the form class of a new word. This study examined 3‐ and 5‐year‐old Mandarin learners' ability to use function words to interpret new words as either nouns or verbs in the absence of the requirement for determiners and inflections in the ambient language. In Experiment 1, 3‐, and 5‐year‐old Mandarin‐speaking children were exposed to eight novel words embedded in sentence frames differing only in the form class markers used. The 5‐year‐olds interpreted the novel words as either nouns or verbs depending on the form class markers they heard, while the 3‐year‐olds learned only the nouns. Experiment 2 confirmed that the 5‐year‐olds understood the function of the verb‐marker. Thus, Mandarin‐speaking children can use function words to distinguish nouns versus verbs, and this ability appears between three and five years of age.  相似文献

The purpose of this study is to evaluate adolescent bystanders' willingness to help and specific help responses as predicted by both individual characteristics (e.g., gender, empathy, victimisation experiences) and situation-specific characteristics (i.e., bystander's relationship with the victim and the presence of another bystander). The study used an experimental vignette method with a sample of Taiwanese adolescents. Participants included 730 seventh graders (49% girls, mean age 12.8 years) attending one middle school in a southern city in Taiwan. Results show that both individual characteristics (e.g., gender, empathy) and a situation-specific characteristic (i.e., the relationship a participant had with the victim) predicted adolescents' willingness to help. However, only individual characteristics predicted adolescents' specific help responses including telling the teacher, telling the bully to stop, and comforting the victims. Directions for future research and implications for interventions and prevention programs are discussed.  相似文献

While integrative and confrontational internal dialogues (IDs) are often treated as opposing and numerous positive functions are ascribed to the former, this paper assumes that integration and confrontation are not mutually exclusive but independent processes. When exploring IDs that simulate social relationships and are described by different configurations of integrative and confrontational characteristics, canonical correlation analysis revealed that in competitive dialogue, the strong confrontational attitude of the dialogue's author is accompanied by the weak integrative attitudes of both ID parties. The more the ID is based on a rivalry between the parties, the lower the levels of bond, support, and insight functions are and the higher the level of substitution is. In persuasive dialogue, the confrontational attitude of the dialogue's author is combined with the integrative attitudes of both parties. The more the ID is based on persuasion, the higher the intensity of substitution, insight, bond, support, and self-guiding is. The findings suggest a synergistic effect of co-occurring integrative and confrontational attitudes in one ID.  相似文献

It remains unclear whether the Interpersonal Psychological Theory of Suicide (IPTS; Joiner, 2005 ) is generalizable to the population or holds more explanatory power for certain subgroups compared to others. The aim of this study was to (1) identify subgroups of individuals who endorsed suicide ideation in the past month based on a range of mental health and demographic variables, (2) compare levels of the IPTS constructs within these subgroups, and (3) test the IPTS predictions for suicide ideation and suicide attempt for each group. Latent class, negative binomial, linear, and logistic regression analyses were conducted on population‐based data obtained from 1,321 adults recruited from Facebook. Among participants reporting suicide ideation, four distinct patterns of risk factors emerged based on age and severity of mental health symptoms. Groups with highly elevated mental health symptoms reported the highest levels of thwarted belongingness and perceived burdensomeness. Tests of the IPTS interactions provided partial support for the theory, primarily in young adults with elevated mental health symptoms. Lack of support found for the IPTS predictions across the subgroups and full sample in this study raise some questions around the broad applicability of the theory.  相似文献

Learning in natural environments is often characterized by a degree of inconsistency from an input. These inconsistencies occur, for example, when learning from more than one source, or when the presence of environmental noise distorts incoming information; as a result, the task faced by the learner becomes ambiguous. In this study, we investigate how learners handle such situations. We focus on the setting where a learner receives and processes a sequence of utterances to master associations between objects and their labels, where the source is inconsistent by design: It uses both “correct” and “incorrect” object‐label pairings. We hypothesize that depending on the order of presentation, the result of the learning may be different. To this end, we consider two types of symbolic learning procedures: the Object‐Label (OL) and the Label‐Object (LO) process. In the OL process, the learner is first exposed to the object, and then the label. In the LO process, this order is reversed. We perform experiments with human subjects, and also construct a computational model that is based on a nonlinear stochastic reinforcement learning algorithm. It is observed experimentally that OL learners are generally better at processing inconsistent input compared to LO learners. We show that the patterns observed in the learning experiments can be reproduced in the simulations if the model includes (a) an ability to regularize the input (and also to do the opposite, i.e., undermatch) and (b) an ability to take account of implicit negative evidence (i.e., interactions among different objects/labels). The model suggests that while both types of learners utilize implicit negative evidence in a similar way, there is a difference in regularization patterns: OL learners regularize the input, whereas LO learners undermatch. As a result, OL learners are able to form a more consistent system of image‐utterance associations, despite the ambiguous learning task.  相似文献

We tested adolescents growing up in institutional care and adolescents living with their birth families using the ‘Do you know?’ scale and other measures of psychosocial functioning. We found that children living in group homes knew significantly less of their family history, exhibited more behavioural problems and had a more external locus of control. Moreover, the correlations between self-esteem and knowledge of family history were significantly different between the groups. This may suggest that the contribution of the knowledge of family history to self-esteem is different depending on the quality of family history. We also found a significant correlation between locus of control and behavioural problems for the children in institutional care, but not children living with their birth families, which may indicate that their behavioural problems may partially stem from the sense of lack of control over their lives.  相似文献

Moos and Moos' (1986) Family Environment Scale (FES) was adapted to the Chinese children and adolescents in Hong Kong. The major sample included 1,174 subjects from three elementary schools and seven high schools. Two subscales, Expressiveness and Independence and a few items were deleted based on the psychometric analysis. The FES scale intercorrelations were consistent, and the factor pattern of the remaining eight scales was explicable in terms of the characteristics of the Chinese culture. Results also showed that middle class families in general had a more positive family social environment than the working class families.  相似文献

In the context of research into scenic quality, the purpose of the present paper is to establish categories of urban landscapes on the basis of users' aesthetic judgements. It also explores the role that the restorative capacity of a place—in terms of the attentional restoration theory (ART)—together with a set of aesthetic attributes, may play in more or less valued places in a city. A total of 132 residents from Málaga (Spain) were chosen, with the city providing the physical framework for environmental reference. A questionnaire designed for easy self‐administration by subjects was used to collect information. Subjects were asked to identify three places in Málaga that they considered to be most attractive and three that they considered least attractive. Participants were asked to evaluate both the restorative properties—in terms of the ART—and the extent to which their first choice displayed certain environmental characteristics. Participants expressed a clear aesthetic preference for recreational sites for leisure/walking as well as those closely linked to the city's historical‐cultural identity. The research also identified other categories of visual settings that could be used as a focal point around which to centre future samples of scenes in a city context. Finally, the results obtained from the characterization of more and less attractive places, from the variables used in this study, shed light on the dimensions of underlying meaning that individuals use to categorize their environment and reinforce the idea that environmental aesthetics seem to play an important role in individuals' general well‐being.  相似文献
