Abstract

Proper names function in our conceptual lives as means for denoting individuals in kinds. Kinds are denoted by common names, more precisely count nouns, and so there are important interrelations between proper names and common nouns. All of this shows up in the way we interpret proper names and employ them in everyday inferences. For example, an airline may count three passengers in relation to a single person Jane, if Jane takes three trips with the airline. Each of the three passengers is Jane, but there is only one Jane. To handle such operations we propose a theory of proper names as part of the theory of kinds. This enables us to specify certain resources (some of them unlearned) that are necessary for the learning of proper names and also a theory of how they are learned. We review the experimental literature on the learning of proper names from the standpoint of the theory. We do not extend the theory to cover recognition or recall.  相似文献

The difficulties inherent in the evaluation of educational software are described in terms of the tradeoffs between internal, external, and ecological validity. Larger issues in evaluation research design and computer-based instruction are highlighted by primary and metaanalytic studies designed to reveal the effects of computer simulations in psychology classrooms and laboratories. The effectiveness of classroom and laboratory computer activities depends on how the inclusion of software, as well as the evaluation process itself, changes the entire instructional process.  相似文献

Two experiments demonstrate that 14‐ to 18‐month‐old toddlers can adaptively change how they categorize a set of objects within a single session, and that this ability is related to vocabulary size. In both experiments, toddlers were presented with a sequential touching task with objects that could be categorized either according to some perceptually salient dimension corresponding to a taxonomic distinction (e.g. animals vs. vehicles) or to some less obvious dimension (e.g. rigid vs. deformable). In each experiment, children with larger productive vocabularies responded to both dimensions, showing evidence of sensitivity to each way of categorizing the items. Children with smaller productive vocabularies attended only to the taxonomically related categorical grouping. These experiments confirm that toddlers can adaptively shift the basis of their categorization and highlight the dynamic interaction between the child and the current task in early categorization.  相似文献

This paper presents some commonly occurring problems associated with integrating a computer component into student psychology laboratories. Implementation of a computer component requires consideration of differences among students, objectives and teaching style of the instructor, course level and content, and courseware to be used. These factors are examined with respect to how they can affect the success of an attempt to use computers in the instructional laboratory.  相似文献

Forty-two adolescent mothers with 2-year-old children were questioned about their sources of social support, their satisfaction with that support, and their views about including members of their informal support network in the receipt of professional services. The results indicated that 74% of the mothers received parenting advice from some professional source, as well as from their informal support network, and that most were satisfied with their professional contacts. Nonetheless, 75% of the mothers indicated that they would like additional parenting advice from parenting classes, organized neighborhood groups, or from visiting public health nurses or other child development specialists. Ninety percent of the mothers thought it would be helpful to have members of their informal support network participate with them in the receipt of professional services, and 81% thought these individuals would be willing to do so. The implications of these findings for both future research and the design and implementation of programs directed toward adolescent parents and their children are discussed.  相似文献

Individuals can often accurately perceive others’ emotions in a purely interpersonal context. However, when people identify with an important ingroup, they experience distinctive patterns of emotion [Smith, E. R., Seger, C. R., & Mackie, D. M. (2007). Can emotions be truly group-level? Evidence regarding four conceptual criteria. Journal of Personality and Social Psychology, 93, 431-446]. Thus, in three studies using a variety of meaningful groups, we examine how a salient distinction between groups might influence people’s ability to estimate the emotions of outgroup members. Participants demonstrated substantial though imperfect accuracy in estimating the emotions reported by outgroups. Specific biases affected their estimates, especially the overlap of perceived emotions of the outgroup with the ingroup’s own emotions. Furthermore, there was a general overprediction of outgroups’ negative emotions and underprediction of their positive emotions. Because of the importance of an outgroup’s emotions as potential causes of their behavior, accuracy and biases in group emotion estimation may be consequential for intergroup relations.  相似文献

Research has shown that bystanders more often fail to or are slower to help a victim in emergency when there are other bystanders than when there are not. The study presented in this paper is a qualitative case study with a focus on students’ own reasons why they do not help a classmate in emergency when there are other children witnessing the emergency situation in the real-life classroom case studied. Grounded theory methods were used to analyse the data. The individual conversations with the students indicated a variety of definitions of the specific distress situation when they recalled and talked about the classroom incident. During the process of the analysis seven concepts of definitions associated with passive or non-intervention bystander behaviour were constructed and grounded in the empirical material: trivialisation, dissociation, embarrassment association, busy working priority, compliance with a competitive norm, audience modelling, and responsibility transfer. Relations between these concepts of definitions were also analysed. However, this study is a first step and a first report from an ongoing study about school children as helper and bystander.  相似文献

A common finding is that there are response-repetition (RR) costs under task switching. Moreover, when the stimulus on the previous trial was congruent then RR costs are usually larger than when it was incongruent. This effect of the previous trial has been explained by assuming that a response category is generally inhibited after the execution of its corresponding response on the previous trial and that the amount of inhibition depends on the activation of the response category. However, up to now it was open which property of the response-category activation on the previous trial is crucial: the absolute activation of the correct response category or the activation difference between the alternative response categories. To differentiate between these two possibilities we compared RR costs after congruent, neutral, and incongruent trials. In two experiments we found similar RR costs after congruent and neutral trials, whereas the RR costs were smaller after incongruent trials. These results support the hypothesis that the amount of response inhibition is determined by the activation differences between the alternative response categories on the previous trial.  相似文献

In 2 experiments, the author explored the relations of remember versus familiar ratings to judgments of frequency (JOFs) and to judgments of recency (JORs). In both cases, remembered items were associated with more accurate memory judgments. In general, familiar items were judged to have occurred less frequently and less recently than remembered items. However, JOFs and JORs associated with familiar items were more accurate than chance. Implications for theories of remember versus familiar ratings, JOFs, and JORs are considered. Some basic findings that constrain these theories are that (a) remember versus familiar ratings were less sensitive than JOF to presentation frequency and less sensitive than JOR to recency and (b) although remember versus familiar ratings are strongly related to both JOF and JOR, as measured by gamma, the relations are far from perfect.  相似文献

In two field studies, we examined whether voters overestimate support for their political party among nonvoters. In Study 1, voters estimated the percentage of votes their party would receive in an upcoming election, and this percentage increased when voters estimated the percentage of votes their party would receive if nonvoters also were to vote. In Study 2, participants overestimated support for their party even when we made them explicitly aware of current levels of this support by presenting them with poll-based forecasts of election results. Furthermore, Study 2 demonstrated that commitment to vote for a specific party predicted the degree of overestimation. Our results imply that highly committed voters are particularly likely to project support for their party onto nonvoters. Implications for the literature on social projection and social identity are discussed.  相似文献

The computer network described was designed to optimize the use of a number of independent minicomputers as a single integrated system for process control of several research laboratories. The implementation of the network required both the development of a special purpose interprocessor interface and the design of a software support system to direct network operations. The network was designed according to the familiar “star” configuration, with the exception that the central computer in the star does not exercise exclusive supervisory control over the system. Rather, each computer on the system “sees” the central computer as a peripheral similar in characteristics to a medium speed I/O device. This design allows each computer to serve not only as a node in the network, but also as an entirely independent process controller.  相似文献

Procedural tasks involve context-sensitive sequences of actions that are performed in pursuit of goals. Procedural knowledge specifies how to do something (e.g., repairing a car) but not how the physical system works (e.g., how the engine works). We have developed a computer program that elicits procedural knowledge from individuals with varying amounts of domain knowledge (ranging from novices to experts) and varying amounts of computer literacy. The tool is called CAT (cognitive analysis tool). CAT is an extension of a class of cognitive models known as GOMS, which stands for goals, operators, methods, and selection rules. The tool guides the user in articulating the goals (and subgoals) the user wants to accomplish, the operators (actions, steps) to accomplish each goal, the alternative methods of accomplishing goals, the conditions in which each method is applied, and exceptional circumstances when goals are suspended and restarted. CAT can be used on most IBMcompatible microcomputers.  相似文献

Spatial organization is an extensively studied field, in which most of the research has been on how the physical environment is perceived and conceived. There is a consensus that physical attributes such as environment geometry and landmarks are key factors in shaping spatial cognition. Nevertheless, the numerous studies of spatial behavior have usually been carried out on individuals, thereby overlooking the possible impact of the social environment. In the present study, rats were exposed to an unfamiliar open-field, first alone and then in tetrads of unfamiliar individuals, in order to monitor and analyze when and how their individual spatial behavior converged to a group spatial behavior. We found that the unfamiliar rats spent most of their time in companionship, first with preferred partners and ultimately as a quartet. Specifically, group formation was dynamic and gradual, with the rats first forming duos, then trios, and ultimately a quartet. Trios and quartets mostly huddled in the same specific corner that became a shared home base, from which they took solo or duo roundtrips to the arena. The present study unveils how, by means of gradual interactions among self, place, and conspecifics, four unfamiliar rats organized together their social spatial behavior.  相似文献

How do children learn to write letters? During writing acquisition, some letters may be more difficult to produce than others because certain movement sequences require more precise motor control (e.g., the rotation that produces curved lines like in letter O or the pointing movement to trace the horizontal bar of a T). Children of ages 6–10 (N = 108) wrote sequences of upper-case letters on a digitizer. They varied in the number of pointing and rotation movements. The data revealed that these movements required compensatory strategies in specific kinematic variables. For pointing movements there was a duration decrease that was compensated by an increase in in-air movement time. Rotation movements were produced with low maximal velocity but high minimal velocity. At all ages there was a global tendency to keep stability in the tempo of writing: pointing movements exhibited a duration trade-off whereas rotation movements required a trade-off on maximal and minimal velocity. The acquisition of letter writing took place between ages 6 and 7. At age 8 the children shifted focus to improving movement control. Writing automation was achieved around age 10 when the children controlled movement duration and fluency. This led to a significant increase in writing speed.  相似文献

Parental monitoring has been conceptualized as tracking and surveillance but operationalized as knowledge of daily activities. This study tested the tracking and surveillance explanation of why parental knowledge is linked to better adolescent adjustment. Participants were 1,186 14-year-olds in central Sweden and their parents. The results supported and extended a reinterpretation of parental monitoring (H. Stattin & M. Kerr, in press). Across sex and informant, high parental knowledge was linked to multiple measures of good adjustment. But children's spontaneous disclosure of information explained more of these relations than parents' tracking and surveillance efforts did. Parents' control efforts were related to good adjustment only after the child's feelings of being controlled, which were linked to poor adjustment, were partialed out. The findings suggest that parents' tracking and surveillance efforts are not as effective as previously thought.  相似文献

Many psychologists avoid using microcomputers in teaching and research laboratories because they lack the experience and knowledge necessary for interfacing. A $1 electronic component can connect external circuits into any computer. For output interfacing, circuits are available to control external devices with one or no additional components.  相似文献

A set of BASIC-callable assembler routines are described that support experimental programming on the PDP-8/e laboratory computer. The package includes both general-purpose laboratory utilities (e.g., for timing delays, sensing and controlling switches, etc.) and specialized functions to facilitate elementary signal processing operations. System performance is evaluated in terms of timing accuracy, optimal sampling rates, and transportability to other laboratories.  相似文献
