This study explored how domestic cats perform in a horizontal string-pulling task to determine whether they understand this
case of physical causality. Fifteen cats were tested on their ability to retrieve an unreachable food treat in three different
set-ups: (a) a single baited string, (b) two parallel strings where only one was baited and (c) two crossed strings where
only one was baited. All cats succeeded at pulling a single string to obtain a treat, but none consistently chose the correct
string when two strings were parallel. When tested with two crossed strings one cat chose the wrong string consistently and
all others performed at chance level. There was no evidence that cats understand the function of the strings or their physical
causality. 相似文献

Strategies that produce generalized responding are valuable, especially with regard to language acquisition, because relatively little training may result in large behavior changes. Conditions that result in generalized manding were analyzed in the current study. We demonstrated in reversal designs that undesirable or single-word responses were the predominant mand forms of 3 preschool children. Multiple baseline designs with 2 participants and a reversal design with 1 participant were then used to demonstrate the extent to which differential reinforcement of single-word mands (e.g., "cars") or framed mands (e.g., "I want the cars, please") would result in the emergence of other single-word and framed mands for different items (e.g., mands for music, puppets, or puzzles). Results showed that prompting and differential reinforcement of one or two mand frames resulted in the emergence of other framed mands for all participants. 相似文献

Joint attention is often referred to as a triadic relation between self, other and object. Young children with autism show
deficiencies in the use of joint attention behaviors. Individual differences may be expected, and they may be determined by
the children’s cognitive development or the characteristics of the relationship of the child with the caregiver. Although
most joint attention skills develop under the age of three, most studies of joint attention in children with autism involved
children older than 3 years of age, due to difficulties in diagnosing autism under this age. In this study we investigated
joint attention behaviors of 78 young children (mean age 25.7 months, SD 6.1) with autism spectrum disorders (n = 20), other developmental delays (n = 18), and typically developing children (n = 40). Following the pertinent literature and confirmed by factor analysis, two types of joint attention behaviors were distinguished,
Basic Joint Attention (BJA) and Associated Joint Attention (AJA). We found that cognitive delays and autistic symptoms—but
not attachment insecurity or disorganization—were related to less joint attention. Already at the age of 2 years, children
with more autistic symptoms show less joint attention, even after controlling for developmental level. 相似文献

Children with Autism Spectrum Disorder (ASD) have severe and pervasive impairments in the development of social interaction,
which may affect the attachment relationship with their parents and may have an impact on parenting. In the current investigation
89 families with young children (mean age 26.5 months) were involved, who were diagnosed as ASD, mentally retarded (MR), or
language delayed (LD), or part of a non-clinical comparison group. Attachment security was observed with the Brief Attachment
Screening Questionnaire, and several parental self-report questionnaires assessed the parenting style, parental efficacy,
parental experiences of daily hassles, social support, and psychological problems. Children with ASD were rated as less secure
compared to the other clinical and normal comparison groups. Parents of non-clinical children reported higher levels of authoritative
parenting than parents in the ASD group and in the total clinical group, and they also received less social support. Parents
of children with ASD coped remarkably well with the challenges of raising a child with ASD. 相似文献

Affect valuation theory (AVT) predicts cultural variation in the affective states that people ideally want to feel (i.e., "ideal affect"). National and ethnic comparisons support this prediction: For instance, European Americans (EA) value high arousal positive (HAP) states (e.g., excitement) more and low arousal positive (LAP) states (e.g., calm) less than Hong Kong Chinese. In this article, the authors examine whether religions differ in the ideal affective states they endorse. The authors predicted that Christianity values HAP more and LAP less than Buddhism. In Study 1, they compared Christian and Buddhist practitioners' ideal affect. In Studies 2 and 3, they compared the endorsement of HAP and LAP in Christian and Buddhist classical texts (e.g., Gospels, Lotus Sutra) and contemporary self-help books (e.g., Your Best Life Now, Art of Happiness). Findings supported predictions, suggesting that AVT applies to religious and to national and ethnic cultures. 相似文献

This study examined the relationships between childhood experiences of parenting and causal attributions for criminal behavior among offenders against the person, property offenders, and non-offenders. Analysis showed that non-offenders perceived their fathers to be warmer and more overprotecting than did person offenders. Person offenders perceived their mothers to be less warm than did property offenders and non-offenders, and less overprotecting than non-offenders. Mothers were perceived to be more overprotecting and warmer than fathers by all 3 groups. All 3 samples viewed a range of explanations to be important in explaining criminal behavior. No significant associations were revealed between perceptions of parenting and causal attributions for crime. Group membership was predicted by home area crime level and perceived parental emotional warmth. 相似文献

Pupils (n=99) from two secondary schools in the UK were interviewed to investigate their views and experiences of the peer counselling for bullying service set up in their school. They were asked about various things concerning (1) the characteristics of the service and service providers that they valued and (2) their reasons for not using the service. Overall, a majority of participants reported a willingness to use this type of service and they identified numerous characteristics that they valued, including peer counsellors with good listening skills who were trustworthy and maintained confidentiality. A noteworthy proportion of participants also wanted the service to provide advice on solving bullying‐related problems. Some barriers to using the service were also identified, including fear of being stigmatised. Responses offered by girls and boys, and by users and non‐users of the service, were compared and several significant differences emerged. The results are discussed in terms of the implications for adults who run this type of service and the peer counsellors who deliver it. 相似文献

Opposite changes in perception (aftereffects) can be simultaneously induced for faces from different social categories—for example, Chinese and Caucasian faces. We investigated whether these aftereffects are generated in high-level face coding that is sensitive to the social category information in faces, or in earlier visual coding sensitive to simple physical differences between faces. We caricatured the race of face stimuli and created face continua ranging from caricatured Caucasian faces (SuperCaucasian) to caricatured Chinese faces (SuperChinese). Participants were adapted to oppositely distorted faces that were a fixed physical distance apart on the morph continua. Larger opposite aftereffects were found following adaptation to faces from different race categories (e.g., contracted Chinese and expanded Caucasian faces), than for faces that were the same physical distance apart on the morph continua, but were within a race category (e.g., contracted SuperChinese and expanded Chinese faces). These results suggest that opposite aftereffects for Chinese and Caucasian faces reflect the recalibration of face neurons tuned to high-level social category information. 相似文献

Probed recall tasks are often used to assess aspects of children's verbal short-term memory development because they are not subject to potentially confounding output effects. However, the marked recency effects that are observed in probed recall means that these tasks are potentially insensitive to experimental manipulations when later serial positions are probed. This clouds the interpretation of data from probed recall studies in which children of different ages are presented with to-be-remembered lists of different lengths. In two experiments we examined the magnitude of phonological similarity and lexicality effects in both 5- to 6- and 8- to 9-year-old children. In each case performance on probed recall tasks was contrasted with that seen on tests of serial recognition. The results indicated that probed recall tasks are potentially less sensitive to experimental manipulations in younger than older children. However, comparable effects of both phonological similarity and lexicality were seen in both age groups using serial recognition procedures. These findings have implications for the interpretation of other studies that have examined the development of verbal short-term memory using probed recall and for theoretical accounts of the development of phonological similarity and lexicality effects in children. 相似文献

This research experimentally investigated whether virtual reality experience can prompt greater empathy and whether greater engagement with a virtual reality connects this virtual reality experience to empathy. Randomly assigned participants viewed a documentary featuring a young girl living in a refugee camp either in a virtual reality format or in a control two-dimensional format. Results indicated that the virtual reality experience resulted in greater engagement and a higher level of empathy for the refugee girl compared to the control condition. Greater engagement was a process connecting the virtual reality experience to empathy. Virtual reality has the potential to influence interpersonal emotions such as empathy. 相似文献
