Semantic features have provided insight into numerous behavioral phenomena concerning concepts, categorization, and semantic
memory in adults, children, and neuropsychological populations. Numerous theories and models in these areas are based on representations
and computations involving semantic features. Consequently, empirically derived semantic feature production norms have played,
and continue to play, a highly useful role in these domains. This article describes a set of feature norms collected from
approximately 725 participants for 541 living (dog) and nonliving (chair) basic-level concepts, the largest such set of norms developed to date. This article describes the norms and numerous statistics
associated with them. Our aim is to make these norms available to facilitate other research, while obviating the need to repeat
the labor-intensive methods involved in collecting and analyzing such norms. The full set of norms may be downloaded from

A: Excuse me, but we're just trying to find the right bus that takes us to the boat for Upolu. We were told that it stops
here in front of the village store, but we've been waiting since 9 o'clock this morning and we'd like to know if there is
going to be a bus before this evening or if we'll have to wait until tomorrow for a bus.
I: Yes. 相似文献

When an object A moves toward an object B until they are adjacent, at which point A stops and B starts moving, we often see a collision--ie we see A as the cause of B's motion. The spatiotemporal parameters which mediate the perception of causality have been explored in many studies, but this work is seldom related to other aspects of perception. Here we report a novel illusion, wherein the perception of causality affects the perceived spatial relations among two objects involved in a collision event: observers systematically underestimate the amount of overlap between two items in an event which is seen as a causal collision. This occurs even when the causal nature of the event is induced by a surrounding context, such that estimates of the amount of overlap in the very same event are much improved when the event is displayed in isolation, without a 'causal' interpretation. This illusion implies that the perception of causality does not proceed completely independently of other visual processes, but can affect the perception of other spatial properties. 相似文献

Perceiving egocentric distance is not only a function of the optical variables to which it relates, but also a function of people's current physiological potential to perform intended actions. In a set of experiments, we showed that, as the effort associated with walking increases, perceived distance increases if the perceiver intends to walk the extent, but not if the perceiver intends to throw. Conversely, as the effort associated with throwing increases, perceived distance increases if people intend to throw to the target, but not if they intend to walk. Perceiving distance combines the geometry of the world with our behavior goals and the potential of our body to achieve these goals. 相似文献

Since 1915, statisticians have been applying Fisher'sZ-transformation to Pearson product-moment correlation coefficients. We offer new geometric interpretations of this transformation. 相似文献

The monetary choice questionnaire (MCQ) and similar computer tasks ask preference questions in order to ascertain indifference,
the perceived equivalence of immediate versus larger delayed rewards. Indifference data are then fitted with a hyperbolic
function, summarizing the decline in perceived value with delay time. We present a fitting method that estimates the hyperbolic
parameterk directly from survey responses. Binary preferences are modeled as a function of time (X2) and a transformed reward ratio (X
1), yielding logistic regression coefficients β2 and β1. The hyperbolic parameter emerges ask = β2/β1, where the logistic predictedp = .5 (the definition of indifference). The MCQ was administered to 1,073 adolescents and was scored using both standard and
logistic methods. The means for ln(k) were similar (standard, −4.53; logistic, −4.51), and the results were highly correlated (ρ = .973). Simulated MCQ data showed
thatk was unbiased, except where β1 ≥ −1, indicating a vague survey response. Jackknife standard errors provided excellent coverage. 相似文献

A three-neuron network (a central pattern generator [CPG]) is both sufficient and necessary to generate aerial respiratory behavior in the pond snail, Lymnaea stagnalis. Aerial respiratory behavior is abolished following a specific nerve crush that results in axotomy to one of the three CPG neurons, RPeD1. Functional regeneration of the crushed neurite occurs within 10 days, allowing aerial respiratory behavior to be restored. Functional regeneration does not occur if the connective is cut rather than crushed. In unaxotomized snails, aerial respiratory behavior can be operantly conditioned, and following memory consolidation, long-term memory (LTM) persists for at least 2 weeks. We used the Lymnaea model system to determine (1) If in naive animals axotomy and the subsequent regeneration result in a nervous system that is competent to mediate associative learning and LTM, and (2) if LTM survives RPeD1 axotomy and the subsequent regenerative process. We show here that (1) A regenerated nervous system is competent to mediate associative memory and LTM, and (2) LTM survives axotomy and the subsequent regenerative process. 相似文献

Honeybees were trained to find sugar water in the middle of an array of two landmarks of different colours. Unrewarded tests
compared searching on the training array with searching on rotated arrays. On rotated tests, a system using the angles between
landmarks would continue to search in the middle. A system using vectors to individual elements would search at locations
outside the rotated array at which the distances and compass directions to a subset of landmarks matched. Results indicated
that bees used both elements and interlandmark angles, but they relied most on one favourite landmark element. Results support
the template model of landmark use in honeybees, with the minor parametric modification that weights given to different elements
may be unequal.

Elementary school is a transitional and impressionable period for any child. In inclusive classroom settings, children with disabilities may experience the challenges of acceptance and integration into peer relationships. The experience of children with disabilities in such classrooms can be positive if their classmates are accepting and open. One way to encourage these attitudes is by increasing awareness through disability-simulation. This study evaluates an existing school program, whose goal is to increase acceptance of others with disability. We surveyed students to assess the influence of the program. An adapted acceptance scale was distributed to students before and after participation in the program. Our hypothesis was that student acceptance would increase after participating in the program. Additionally, we hypothesized that physical, visual, and auditory disabilities would be easier for students to understand, making acceptance scores for these disabilities higher than those for a learning disability. We report changes in acceptance using group means. Our results reveal that post-survey responses showed higher acceptance than pre-survey responses, especially for auditory disabilities. Other significant findings include differences in attitudes between the two schools and differences based on prior experience with someone with a disability. By evaluating the effectiveness of this type of program (whose efficacy has been controversial in the literature), this study can provide teachers, administrators, genetic counselors, and parents with a better idea of how to address children’s attitudes towards peers. In our study, the effectiveness of promoting understanding through disability-simulation has proven its worth to improve children’s acceptance. 相似文献
