Animal communication involves very dynamic processes that can generate new uses and functions for established communicative activities. In this article, the authors describe how an aposematic signal, the rattling sound of rattlesnakes (Crotalus viridis), has been exploited by 2 ecological associates of rattlesnakes: (a) California ground squirrels (Spermophilus beecheyi) use incidental acoustic cues in rattling sounds to assess the danger posed by the rattling snake, and (b) burrowing owls (Athene cunicularia) defend themselves against mammalian predators by mimicking the sound of rattling. The remarkable similarity between the burrowing owl's defensive hiss and the rattlesnake's rattling reflects both exaptation and adaptation. Such exploitation of the rattling sound has favored alternations in both the structure and the deployment of rattling by rattlesnakes. 相似文献

Participants were 55 children with attention deficit hyperactivity disorder (ADHD) who were receiving ongoing treatment with stimulant medications and their mothers, and 31 children with ADHD who were beginning stimulant medication and their mothers. Mothers and children offered attributions for child behaviors that occurred when the child was medicated and not medicated. Mothers rated child compliance and prosocial behavior as more global and stable when the child was medicated and rated noncompliance, ADHD symptoms, and oppositional behavior as more externally caused, less global and stable, but more controllable by the child when the child was medicated. Children rated both their compliance and noncompliance as more controllable in the medicated condition. On a forced-choice measure, both mothers and children selected ability, effort, and task attributions for compliance more in the not-medicated condition, and pill-taking attributions more in the medicated condition. This was reversed for noncompliance, which was attributed more to effort, task, or ability in the medicated condition and more to not taking a pill in the not-medicated condition. The potential risks and benefits for parent–child interactions and children's self-perceptions of these medication-related differences in attributions are discussed. 相似文献

Hundreds of research articles have addressed the relationship between birth order and intelligence. Virtually all have used cross-sectional data, which are fundamentally flawed in the assessment of within-family (including birth order) processes. Although within-family models have been based on patterns in cross-sectional data, a number of equally plausible between-family explanations also exist. Within-family (preferably intact-family) data are prerequisite for separating within- and between-family causal processes. This observation reframes an old issue in a way that can be easily addressed by studying graphical patterns. Sibling data from the National Longitudinal Survey of Youth are evaluated, and the results are compared with those from other studies using within-family data. It appears that although low-IQ parents have been making large families, large families do not make low-IQ children in modern U.S. society. The apparent relation between birth order and intelligence has been a methodological illusion. 相似文献

The Toulmin diagram layout is very familiar and widely used, particularly in the teaching of critical thinking skills. The
conventional box-and-arrow diagram is equally familiar and widespread. Translation between the two throws up a number of interesting
challenges. Some of these challenges (such as the relationship between Toulmin warrants and their counterparts in traditional
diagrams) represent slightly different ways of looking at old and deep theoretical questions. Others (such as how to allow
Toulmin diagrams to be recursive) are diagrammatic versions of questions that have already been addressed in artificial intelligence
models of argument. But there are further questions (such as the relationships between refutations, rebuttals and undercutters,
and the roles of multiple warrants) that are posed as a specific result of examining the diagram inter-translation problem.
These three classes of problems are discussed. To the first class are addressed solutions based on engineering pragmatism;
to the second class, are addressed solutions drawn from the appropriate literature; and to the third class, fuller exploration
is offered justifying the approaches taken in developing solutions that offer both pragmatic utility and theoretical interest.
Finally, these solutions are explored briefly in the context of the Araucaria system, showing the ways in which analysts can tackle arguments either using one diagrammatic style or another, or even a
combination of the two. 相似文献

This article examined the applicability of the interpersonal circumplex (IC) to the observable social behaviors of children during parent-child interactions. In Study 1, the observational ratings of behaviors of 117 children (mean age = 9.88 years) were examined. Randomization tests of hypothesized order relations found that these behaviors tended to occur in the circular pattern predicted by the IC. To illustrate the applicability of the IC to children's behavior, Study 2 (n = 94) used the circular structure of children's behavior to longitudinally examine children's participation in two risk behaviors, smoking cigarettes and consuming alcohol. Results indicated that children who behaved in an arrogant-calculating manner were at risk for smoking cigarettes and children who behaved in an assured-dominate manner were at risk for drinking alcohol 1 year later. Implications of these results are discussed in terms of their relevance for helping researchers better understand and categorize children's interpersonal behaviors. 相似文献

In a first stage of training, participants learned to associate four visual cues (two different colors and two different shapes)
with verbal labels. For Group S, one label was applied to both colors and another to both shapes; for Group D, one label was
applied to one color and one shape, and the other label to the other cues. When subsequently required to learn a task in which
a given motor response was required to one of the colors and one of the shapes, and a different response to the other color
and the other shape, Group D learned more readily than Group S. The task was designed so that the associations formed during
the first stage of training could not generate differential transfer to the second stage. The results are consistent, however,
with the proposal that training in which similar cues are followed by different outcomes will engage a learning process that
boosts the attention paid to features that distinguish these cues. 相似文献

Current models of adult arithmetic performance assume that representation includes only facts and procedures. However, other kinds of representations such as an analog scale or sets of number multiples might be useful in a variety of multiplication-related tasks. Introducing the practice transfer paradigm, we demonstrate that associations between distinct representational structures can be detected via cross-task transfer, provided that initial performance is retrieval based. Results support the predictions of the integrated-structures model of multiplication knowledge. Implications for well-established item differences such as the problem-size effect are addressed, and the question of how integration occurs is considered. 相似文献
