Since I do not disagree with the line of argument taken by Kramer and the distinctions he draws between the different ways
rules can be ‘mind-independent’, my comments focus on some of the complexities involved in the application of his distinctions.
I suggest that law, properly understood as a system of rules/conventions is both existentially and observationally weakly mind independent, but nonetheless objective.

In this paper we consider the perceptual and conceptual contributions that shape early word learning, using research on the shape bias as a case in point. In our view, conceptual, linguistic, social-pragmatic, and perceptual sources of information influence one another powerfully and continuously in the service of word learning throughout infancy and early childhood. We articulate several key points of convergence and divergence between our theoretical perspective and that of the attentional learning account. Finally, we consider the broader implications of this debate for clarifying the forces that constrain development. 相似文献

Assessment of irrational beliefs by such measures as the Common Beliefs Survey III (CBS) has traditionally relied upon classical
test theory assumptions, in which the properties of specific test items are less important than the total test score as the
aggregate of all item responses. An alternative approach using item response theory (IRT) methodology allows one to specify
the parameters of difficulty and discrimination for each test item. Difficulty levels of CBS items range along a continuum of irrationality, the implied latent trait measured by responses to the questionnaire as a whole. We evaluated the CBS responses of 605 individuals
from clinical and college settings, drawing from current and archival data. The original Likert scale ratings were recoded
into dichotomous scores. Fourteen of the 54 items were highly or very highly discriminating in distinguishing respondents
with high and low irrationality levels. However, discriminating items exhibited a very narrow range of difficulty; most functioned
at a point a little above the halfway mark on the continuum of irrationality. Item characteristic curves and test information
curves were very similar for female (n = 424) and male (n = 179) respondents. We derived a 4-item screening test for irrationality from our IRT analyses of the 54 CBS items. Further
test development, focused on the selection and scaling of items with a much broader range of difficulty, would facilitate
evaluation of the hierarchical structure of irrational beliefs.

Smoking is highly prevalent across most anxiety disorders. Tobacco use increases risk for the later development of certain anxiety disorders, and smokers with anxiety disorders have more severe withdrawal symptoms during smoking cessation than smokers without anxiety disorders. The authors critically examined the relationships among anxiety, anxiety disorders, tobacco use, and nicotine dependence and reviewed the existing empirical literature. Future research is needed to better understand the interrelationships among these variables, including predictors, moderators, and mechanisms of action. Increased knowledge in these areas should inform prevention efforts as well as the development and improvement of smoking cessation programs for those with anxiety and other psychiatric disorders. 相似文献

Visuomotor association learning involves learning to make a motor response to an arbitrary visual stimulus. This learning is essential for visual search and discrimination performance and is reliant upon a well-defined neural circuit in the brain that includes the prefrontal cortex and the hippocampal formation. In the present study, we investigated the possible role of attentional processes during such learning using dual-task interference. A motor, verbal, or perceptual concurrent task was performed during the learning/training block of a simple visual discrimination task. Contrary to expectation, the dual-task groups showed improved learning and learning-dependent performance compared with untrained control and non-dual-task trained groups. A second experiment revealed that this effect did not appear to be due to increased arousal level; the inclusion of alerting tones during learning did not result in facilitation. These findings suggest that the engagement of attention, but not arousal, during the acquisition of a visuomotor association can facilitate this learning and its expression. 相似文献

Successful reading instruction entails not only acquiring new words but also remembering them after training has finished and accessing their word-specific representations when they are encountered in new text. We report two studies demonstrating that acquisition, retention, and transfer of unfamiliar words were affected differentially by isolated word and context training. Materials were individualized to include only those words that average readers in second grade were unable to name in context. Different words were trained in each condition; context training presented words in stories, and isolated word training presented words on flashcards. Together, the studies show that context training promotes word acquisition beyond that experienced from reading words in isolation. Contrary to the prevailing opinion, memory performance for words trained in context and in isolation did not differ; children demonstrated excellent retention over an 8-day interval in both conditions. Finally, transfer was maximized when the congruency between training and testing was high. Therefore, when reading trained words in novel circumstances, the best method of training was mediated by the transfer task employed at test. 相似文献

Our visual world can be thought of as organised in a hierarchical manner. Studies on hierarchical letter stimuli (a large letter composed of smaller letters) suggest that processing of a visual scene is global to local, a phenomenon known as the global-precedence effect. Elaborating on this global-to-local hypothesis we tested whether global interference will increase with increasing level of globality. For this, we used three-level hierarchical letter stimuli with a global, middle, and local level. When attending to the local level of the stimulus, only the middle level showed an interference effect, whereas the global level did not interfere at all. We argue that, considering the perceptual and attentional contributions to this effect, the hypothesis of global-to-local processing of a visual scene may only hold within a limited spatial attentional window. 相似文献

Classification of suicides is essential for clinicians to better identify self-harm patients with future suicidal risks. This study examined potential subtypes of suicide in a psychological autopsy sample (N = 148) in Hong Kong. Hierarchical cluster analysis extracted two subgroups of subjects in terms of expressed deliberation assessed by the Beck Suicide Intent Scale (SIS). The first group was associated with charcoal burning suicide, no psychiatric illness, indebtedness, better problem-solving ability, chronic stress, and higher overall SIS scores. The second group was associated with jumping from a height, psychotic disorders, psychiatric treatment, acute stress, and lower overall SIS score. The existence of a substantial cluster of subjects with lower expressed intent and preparation has important implications for the performance of the SIS as a predictive tool. Suicide prevention strategy may have to target potential subgroups with specific approaches. 相似文献

An a priori test of the difference engine model (Myerson, Hale, Zheng, Jenkins, & Widaman, 2003) was conducted using a large,
diverse sample of individuals who performed three speeded verbal tasks and three speeded visuospatial tasks. Results demonstrated
that, as predicted by the model, the group standard deviation (SD) on any task was proportional to the amount of processing
required by that task. Both individual performances as well as those of fast and slow subgroups could be accurately predicted
by the model using no free parameters, just an individual or subgroup’s mean z-score and the values of theoretical constructs
estimated from fits to the group SDs. Taken together, these results are consistent with post hoc analyses reported by Myerson
et al. and provide even stronger supporting evidence. In particular, the ability to make quantitative predictions without
using any free parameters provides the clearest demonstration to date of the power of an analytic approach on the basis of
the difference engine. 相似文献
