Writers typically spend a certain proportion of time looking back over the text that they have written. This is likely to serve a number of different functions, which are currently poorly understood. In this article, we present two systems, ScriptLog+TimeLine and EyeWrite, that adopt different and complementary approaches to exploring this activity by collecting and analyzing combined eye movement and keystroke data from writers composing extended texts. ScriptLog+TimeLine is a system that is based on an existing keystroke-logging program and uses heuristic, pattern-matching methods to identify reading episodes within eye movement data. EyeWrite is an integrated editor and analysis system that permits identification of the words that the writer fixates and their location within the developing text. We demonstrate how the methods instantiated within these systems can be used to make sense of the large amount of data generated by eyetracking and keystroke logging in order to inform understanding of the cognitive processes that underlie written text production.  相似文献

The biological foundations of cognitive science   总被引:1,自引:0,他引:1  
Cognitive Science originated in reactions against behaviorism that were motivated in significant part by the example of the computer. The computer raised the exciting possibility that mind could be understood almost entirely independently of brain: if the operations of the mind are akin to the execution of a program, then almost all the relevant aspects of mind would be captured by that program, independently of whatever was running it, be it transistors or neurons. This presumed independence of cognitive science from biology has waned considerably in recent decades, but in this paper, I argue that there is at least one crucial aspect of biology that has yet to be appreciated for its relevance to mental and other normative processes—the thermodynamics of living systems. In particular, I argue that the emergence of normativity in general—and normative function and representation in particular—depends on special systems that are far from thermodynamic equilibrium; these form the interface between the factual world of atoms and molecules and the normative world of mind. The nature of that emergence, in turn, imposes strong constraints on how the central nervous system functions, and, therefore, on how cognition is realized.  相似文献

Hope is a higher-order cognitive construct that encompasses the belief in one’s ability to accomplish personal goals. Hope has been conceptualised as consisting of two constructs – Pathways (the individual’s perceived means available to achieve goals) and Agency (belief in ones ability to succeed in using the identified Pathways). This study aimed to validate a measure of hope, the Dispositional Hope Scale (DHS: [Snyder, C. R., Harris, C., Anderson, J. R., Holleran, S. A., Irving, L. M., Sigman, S. T., et al. (1991). The will and the ways: Development and validation of an individual differences measure of hope. Journal of Personality and Social Psychology, 60(4), 570–585]) in a large sample of traumatic injury survivors (N = 1025). The findings support the psychometric properties of the scale, as well as the two-factor structure of Agency and Pathways, in this population. This study provides support for the use of the DHS as a measure of hope in traumatised populations.  相似文献

Based on the standard error of measurement, Holland (1985) suggested the “rule of eight” for determining the meaningfulness of differences between two summary scores on the Self Directed Search. The present study empirically examined the rule's validity for practice. The participants were 2397 (1497 females and 900 males) undergraduate students enrolled in the exploratory major at a large Midwestern university. The results strongly supported the interpretive rule of eight. For those participants who scored a primary-code distinction of eight or more points, the hit rate was 55% with a kappa of .38. This compared to a hit rate of 40% with a kappa of .21 for those participants with less than eight-point distinction between their top two scores. The authors also discuss the practical implications for interpreting SDS results using the “rule of eight.”  相似文献

Transition is important in the career literature as it identifies times at which people are often likely to consult counselors about issues for which they need help. However, the counseling literature has not provided a conceptualization of, or research on, the joint, goal-directed actions and projects of the counselor and the client, which explicitly reflect the goal-directed nature of the transition itself. To address this issue, 12 counseling dyads, representing 37 counseling sessions, were studied. In these dyads, counseling was observed as the joint, goal-directed action between professional counselors and youth who sought assistance with their transition to adulthood. The data were collected using the action-project method. The counseling sessions were video-recorded, then immediately played back for the counselor and client separately to gather their recalled thoughts and feeling during counseling. Detailed qualitative analysis of the data set addressed the research question, “What are the goal-directed projects that counselors and their clients jointly construct, articulate, and enact relevant to the transition to adulthood?” The findings indicated the relationship and identity are intertwined goal-directed projects within counseling as well as outside of it. These projects contributed to the reframing and reorganization of clients' transition projects outside of counseling in occupational, educational, and familial domains. The findings suggest important implications for counseling youth in transition, that is, counselors and clients explicitly address their joint relationship and identity goals in an effort to realize a mutually satisfactory and important transition to adulthood.  相似文献

The focus of this paper is mechanisms that may be responsible for intellectual and developmental differences in the cognitive strategies of typical and atypical children, including those with mental retardation. The discussion of these mechanisms is based on behavioral experiments on external memory strategies and on a set of neural network models designed for these tasks. Following the review of the external memory research, the rationale for using neural network models, how they have been used in other research, and their specific application to intellectual and developmental differences in external memory, including the results of several simulations, are reviewed. This is followed by a discussion of the mechanisms of intellectual differences and developmental change included in the models and some challenges for this type of modeling. Neural network modeling is discussed as an asset to research on cognitive development.  相似文献

The use of multi-method, multi-informant assessment is a hallmark of research in child development and mental health; however, many research strategies such as population surveys require brief assessment tools. The Alabama Parenting Questionnaire (APQ) is a popular measure of empirically identified aspects of positive and negative parenting styles important to conduct problems in children. A brief version exists, however it does not measure all relevant parenting domains, and it has not been validated for child reports. We evaluated validity of the brief parent and child report version of the complete five subscale version of the APQ in a sample of 208 children aged between 9 and 17, at risk for conduct problems and antisocial behaviour. The results showed that all five dimensions of parenting can be measured using a brief 15 item version; specifically child and parent reports converged as expected and discriminated high from low conduct problem children using parent and teacher reports. Only child reports converged with independent observations of parenting behaviour, supporting previous research showing that child reports of parenting are particularly important. Finally, results did not support the typical methods used for combining child and parent reports into one index.  相似文献
