Humans can efficiently detect a face among non-face objects, but few studies of this ability have been conducted in animals. Here, in Japanese macaques and humans, we examined visual searching for a face and explored what factors contribute to efficient facial information processing. Subjects were asked to search for an odd target among the different numbers of distracters. Faces of the subjects’ own species, the backs of the head of the subjects’ own species, faces of the subjects’ closely related species or race, and faces of species that are clearly different from the subjects’ own species were used as the target. Both the macaques and humans detected a face of their own species more efficiently than a face from a clearly different species. Similar efficient detections were confirmed for the faces of the subjects’ closely related species or race. These results suggest that conspecific faces and faces that share morphological similarity with conspecific faces can be detected efficiently among non-face objects by both humans and Japanese macaques. In another experiment, facial recognition efficiency was observed when the subjects searched for own-species faces that had lower-spatial-frequency components compared to faces with higher-spatial-frequency components. It seems reasonable that the ability to search efficiently for faces by using holistic face processing is derived from fundamental social cognition abilities that are broadly shared among species.  相似文献

Using a questionnaire survey, this study probed into interpersonal cues and characteristics of teachers’ high maintenance behaviors perceived by university students and their coping strategies, and then analyzed the relationship between their perceived high maintenance behaviors and the dimensions of their coping strategies. The Scale of Teachers’ High maintenance Behaviors and the Scale of Coping with Teachers’ High maintenance Behaviors were used as the measurement tools. The subjects were 248 university students, of which 59.3 % were male and 40.7 % were female. According to the research results, the subjects mostly suggested that they define teachers as being high maintenance after getting along with them for one to two weeks and communicating with them using 6–20 sentences. The subjects also suggested that the ranking of the behavioral characteristics of the most significant high maintenance behaviors of teachers is: being old-fashioned, followed by rule followers, idealization, and irresponsible opinions. According to the scores, the ranking of the subjects’ coping strategies for high maintenance behaviors of teachers is obedience and endurance, followed by gentle resistance, compromise, and obvious unhappiness. There is a significant correlation between teachers’ high maintenance behaviors perceived by university students and the dimensions of their coping strategies. It was found that teachers’ high maintenance behaviors perceived by university students could significantly predict the dimensions of coping strategies. Based on the above, this study proposed some suggestions and provided a discussion for university teachers and future studies.  相似文献

Abstract

Previous research suggests that using Fitts’ law; attentional focus or challenge point framework (CPF) is beneficial in balance control studies. A scoping review was conducted to examine studies that utilized these motor behavior concepts during balance control tasks. An extensive literature search was performed up to January 2018. Two independent reviewers conducted a study selection process followed by data extraction of the search results. Forty-six studies were identified, with 2 studies related to CPF, 12 studies related to Fitts’ law and 32 studies related to focus of attention. The CPF appears to be a useful method for designing a progressive therapeutic program. Fitts’ law can be used as a tool for controlling the difficulty of motor tasks. Focus of attention studies indicate that adopting an external focus of attention improves task performance. Overall, studies included in this review report benefit when using the selected motor behavior concepts. However, the majority (>80%) of studies included in the review involved healthy populations, with only three clinical trials. In order to ascertain the benefits of the selected motor behavior concepts in clinical settings, future research should focus on using these concepts for clinical trials to examine balance control among people with balance impairments.  相似文献

Health Maintenance Organization (HMO) administrators have been accused of engaging in ‘selective marketing’. That is, through such strategies as tailoring the benefits package of the program or advertising in styles or in media that do not appeal to certain ‘undesirable’ audiences, the administrator can minimize the percentage of persons in the HMO who are heavy users of health care services. By means of analyzing what ‘insurance’ is (philosophically) and what it means for something to be a free market commodity, the author argues that, as long as American society chooses to regard health insurance as a commodity or service of the free market, the use of such strategies is within the moral rights of health administrators. The author concludes by noting some morally undesirable results of treating health insurance as a market commodity.  相似文献

Several studies employed different algorithms in order to investigate criminal's spatial behaviour and to identify mental models and cognitive strategies related to it. So far, a number of geographic profiling (GP) software have been implemented to analyse mobility and its relation to the way criminals are using spatial environment when committing a crime. Since crimes are usually perpetrated in the offender's high-awareness areas, those cognitive maps can be employed to create a map of the criminal's operating area to help investigators to circumscribe search areas. The aim of the present study was to verify accuracy of simple statistical analysis in predicting spatial mobility of a group of 30 non-criminal subjects. Results showed that statistics such as Mean Centre and Standard Distance were accurate in elaborating a GP for each subject according to the mobility area provided. Future analysis will be implemented using mobility information of criminal subjects and location-based software to verify whether there is a cognitive spatial strategy employed by them when planning and committing a crime.  相似文献

The adverse social and physical conditions of homelessness pose significant developmental risks for children, which may be compounded or buffered by the quality of parenting behaviour they are exposed to. There is currently a limited understanding of how parents approach their care-giving role and responsibilities while adjusting to the experience of homelessness. Advancing knowledge in this area is essential for developing acceptable, appropriate and effective interventions to support highly marginalised and vulnerable homeless families. This review explored homeless parents’ perceptions of how homelessness affects their parenting behaviour and identified adaptive strategies that parents may use to mitigate the potentially negative impacts of homelessness on the quality of care-giving. A systematic search of four electronic databases (ASSIA, PsycINFO, Web of Science and MEDLINE) identified 13 published qualitative studies, all originating from the USA, which explored parenting behaviour in homeless contexts. The studies were critically appraised using the CASP qualitative assessment tool. Thematic synthesis identified the following determinants of parenting behaviour; negative self-concept in the parental role, parental mental health, material resources, challenges to autonomy and self-efficacy, daily hassles, physical environment and service context, stigma, child characteristics and lack of support. These were synthesised thematically using existing models of parenting determinants and positive parenting. Findings indicate substantive impacts of homelessness on parental mental health, parenting authority, material resources, parenting environments and social support. Parents developed a number of adaptive methods to negotiate the challenges of homeless parenting such as maintaining a positive mindset, cherishing the parental role and developing practical strategies. We conclude with recommendations that service providers should tailor parenting support to resource-constrained circumstances and that further research is required in order to better understand experiences of homeless parents in other international contexts.  相似文献

以网名为材料, 通过三项视觉搜索实验考察了与自我相关的网络信息可能存在的加工优势。结果发现, 自己的网名在作为靶刺激时可以更快且更准确地被探测出来; 而在作为干扰刺激时, 其对于靶刺激却并未表现出比对照刺激更强的抑制作用。在与真实人名进行的直接比较中, 自己的网名与真实人名的加工成绩未出现显著差异, 且都好于作为对照的名人名字。这些结果证明了与自我相关的网络信息具有和物理世界中的自我信息相似的加工优势, 且与以真实人名为材料的多项实验结果完全一致, 从而表明自己的网名与真实人名可能具有相同的加工机制。  相似文献

An experiment examines the effect of time constraints on the ability of subjects to utilize relevant information during problem solving. Previous studies found that potentially relevant information was not effectively utilized unless subjects were explicitly informed of the information’s relevance to the problem. The present study demonstrates that subjects who are not informed of the relation between relevant information and the problem are still able to access the information if allowed adequate time. These findings are interpreted within a model of problem solving that postulates search in a problem space as fundamental to the problem solving process.  相似文献

There is evidence to suggest that maternal incarceration can have negative implications for children. Children in these families can be at greater risk for conduct problems and antisocial behavior, as well as school dropout and academic failure. Institution-based parenting programs represent one means of addressing the potential negative impacts of maternal incarceration on children’s wellbeing. Through parent training programs, mothers may develop skills and strategies to help their children cope with the challenges and stressors associated with incarceration. However, it is currently unclear whether parenting programs for mothers in these facilities have a positive effect on different parenting outcomes. We conducted a systematic search of several electronic databases using key search terms and identified sixteen treatment studies. The results suggest that in the short-term, corrections-based parenting programs are associated with positive effects on parenting behavior, parenting attitudes, and parenting knowledge. However, these programs appear to have no effect on parenting stress immediately post-treatment. Implications for practice and recommendations for future research are discussed.  相似文献

Courseware for Observational Research (COR Version 2) is an interactive multimedia program designed to teach the foundation of the scientific method: systematic observation. COR uses digital video with interactive coding to teach basic concepts, such as creating precise operational definitions; using frequency, interval, and duration coding; developing sampling strategies; and analyzing and interpreting data. Through lessons, a case study, and laboratory exercises, it gradually scaffolds students from teacher-directed learning into self-directed learning. The newest addition to COR is a case study in which students work collaboratively, using their own observations to make recommendations about a child’s disruptive behavior in an after-school program. Evaluations of the lessons showed that classes using COR received better grades on their field observations than did those using methods that are more traditional. Students’ confidence and knowledge increased as they moved through each section of the program.  相似文献

Dual Space Search During Scientific Reasoning   总被引:3,自引:0,他引:3  
The purpose of the two studies reported here was to develop an integrated model of the scientific reasoning process. Subjects were placed in a simulated scientific discovery context by first teaching them how to use an electronic device and then asking them to discover how a hitherto unencountered function worked. To do this task, subjects had to formulate hypotheses based on their prior knowledge, conduct experiments, and evaluate the results of their experiments. In the first study, using 20 adult subjects, we identified two main strategies that subjects used to generate new hypotheses. One strategy was to search memory and the other was to generalize from the results of previous experiments. We described the former group as searching an hypothesis space, and the latter as searching an experiment space. In a second study, with 10 adults, we investigated how subjects search the hypothesis space by instructing them to state all the hypotheses that they could think of prior to conducting any experiments. Following this phase, subjects were then allowed to conduct experiments. Subjects who could not think of the correct rule in the hypothesis generation phase discovered the correct rule only by generalizing from the results of experiments in the experimental phase.
Both studies provide support for the view that scientific reasoning can be characterized as search in two problem spaces. By extending Simon and Lea's (1974) Generalized Rule Inducer, we present a general model of Scientific Discovery as Dual Search (SDDS) that shows how search in two problem spaces (an hypothesis space and an experiment space) shapes hypothesis generation, experimental design, and the evaluation of hypotheses. The model also shows how these processes interact with each other. Finally, we interpret earlier findings about the psychology of scientific reasoning in terms of the SDDS model.  相似文献

Two related field studies investigated social stereotyping and differentiation between student groups in higher education. In the first, subjects from Exeter and Manchester Universities rated students at both institutions on a number of evaluatively positive attributes. They also judged the degree status and prospective employment opportunities of the groups, in a context which rendered these important. Although subjects displayed strategies of positive differentiation, this was restricted to certain ‘consensual’ dimensions, reflecting perceived stereotypic differences between the groups. Discrepancies in the pattern of differentiation between the groups, and with finding of comparable studies, are discussed. This paradigm was then extended to the case where Manchester University subjects rated three groups, including the ingroup (Oxford or Exeter University vs. Manchester University vs. Manchester Polytechnic students). From social identity theory it was predicted that comparisons with a higher status outgroup which also excelled on contextually important dimensions (Oxford/Exeter), would increase positive differentiation of the ingroup from a second, lower status outgroup (Manchester Polytechnic students). This was confirmed, although there was weaker evidence for devaluation of the second outgroup in absolute terms. In both studies the relation of group status and dimensional importance of the material factor of career prospects helped to explain the strategies of differentiation adopted.  相似文献

The use of “process-tracing” techniques for examining individuals’ decision strategies has been criticized widely for yielding results that are uninformative and often confounded. The present paper describes a new technique based on a “structural” approach that allows efficient assessment of finely discriminated decision strategies via a HyperCard program called DECOUT. The program presents individuals with an information matrix (e.g., describing five alternative pesticides on three attributes). Individuals are asked to choose the best or the worst alternative in the matrix for 12 problems. Information in the matrix is constructed so that choice of an alternative by an individual is uniquely associated with use of one particular decision strategy. The strategies include information integration, maximin, maximax, pessimism-optimism, and minimax-regret processes. An experiment using the program is described, and possible directions for future research and development are discussed.  相似文献

采用眼动追踪范式,本研究通过两个实验探讨局部注意干扰效应(LAI)的注意分配特点和机制。实验一采用搜索时间有限的范式,目标呈现70毫秒后消失,在行为和眼动指标上均发现LAI效应:当两个目标距离较近时,反应时增加,正确率降低,总注视时长增长、注视点增加和眼跳速度加快。实验二增加目标呈现时间至1500毫秒以鼓励搜索,产生了比实验一更强烈的LAI效应,且眼跳速度的模式也有不同,说明增加搜索时间并不利于减轻LAI,从而推断LAI的竞争发生在判断阶段,而非搜索和识别目标阶段。  相似文献

Despite work’s importance in people’s overall sense of purpose in life, several studies measuring momentary well-being find that people are very unhappy while at work. These studies have focused on workers in industrialized countries doing paid labor in the formal sector. For a large fraction of humanity, however, “work” is smallholder farming, tending cattle and collecting water and fuelwood. We measure momentary well-being with the Experience Sampling Method in a sample of 195 subjects in rural Kenya. Subjects were the household’s main water carrier; 93% were women. Each subject was asked to complete four ESM surveys per day over eight weeks. Results from 9559 ESM records show that subjects are indeed less happy “at work”, whether that work is paid or unpaid casual labor, paid formal sector employment, or resource collection. They are also less energetic, less sociable and in more pain. We also find evidence that subjects perceive themselves as less safe while working or traveling away from home. We find a statistically significant, though small, relationship between the intercepts in the model (individual-level average momentary well-being) and the log of household wages earned over the past two weeks. The relationship is stronger with wages earned by the subject herself.

Past research on delinquency and crime has provided convincing data about correlates but not about causes, because it has been largely cross-sectional in design. Whereas cross-sectional research focuses on variations between subjects, longitudinal research can provide information about changes within subjects, which are more important for causes, prevention, and treatment. Many of the most important results in criminology have been obtained in longitudinal or experimental studies, and the major studies of these types are reviewed here. It is now desirable to combine the two methods in a new coordinated program of longitudinal studies including experimental interventions or quasi-experimental analyses. Such projects could study several overlapping cohorts, extend from birth to adulthood, have frequent data collection, and obtain data from a variety of sources about many different types of antisocial behavior.  相似文献

This study presents a process model of very long-term episodic memory. The process presented is a reconstructive process. The process involves application of three kinds of reconstructive strategies—component-to-context instantiation strategies, component-instantiation strategies, and context-to-context instantiation strategies. The first is used to direct search to appropriate conceptual categories in memory. The other two are used to direct search within the chosen conceptual category. A fourth type of strategy, called executive search strategies, guide search for concepts related to the one targeted for retrieval. A conceptual memory organization implied by human reconstructive memory is presented along with examples which motivate it. A basic retrieval algorithm is presented for traversing that stucture. Retrieval strategies arise from failures in that algorithm. The memory organization and retrieval processes are implemented in a computer program called CYRUS which stores events in the lives of former Secretaries of State Cyrus Vance and Edmund Muskie and answers questions posed in English concerning that information. Examples which motivate the process model are drawn from protocols of human memory search. Examples of CYRUS's behavior demonstrate the implemented process model. Conclusions are drawn concerning retrieval failures and the relationship of episodic and semantic memory.  相似文献
