It is widely held that hearers grasp an utterance's truth conditions by assigning contents to the linguistic expressions used, and combining these contents according to semantic composition rules. To preserve compositionality of truth-conditional content while accounting for context-sensitivity that is not traceable to overt linguistic form, semanticists posit covert linguistic structure. The strongest justification for this approach is the allegedly unconstrained nature of the alternative, whereby a process of 'free pragmatic enrichment' supplies constituents of content that are not traceable to (overt or covert) encoded meaning. This paper argues that free enrichment is tightly constrained by purely pragmatic factors, thus undermining the motivation for semantic compositionality. 相似文献

While viewing faces, human adults often demonstrate a natural gaze bias towards the left visual field, that is, the right
side of the viewee’s face is often inspected first and for longer periods. Using a preferential looking paradigm, we demonstrate
that this bias is neither uniquely human nor limited to primates, and provide evidence to help elucidate its biological function
within a broader social cognitive framework. We observed that 6-month-old infants showed a wider tendency for left gaze preference
towards objects and faces of different species and orientation, while in adults the bias appears only towards upright human
faces. Rhesus monkeys showed a left gaze bias towards upright human and monkey faces, but not towards inverted faces. Domestic
dogs, however, only demonstrated a left gaze bias towards human faces, but not towards monkey or dog faces, nor to inanimate
object images. Our findings suggest that face- and species-sensitive gaze asymmetry is more widespread in the animal kingdom
than previously recognised, is not constrained by attentional or scanning bias, and could be shaped by experience to develop
adaptive behavioural significance. 相似文献

Few studies have examined the impact of children with genetic disorders and their unaffected siblings on family functioning. In this study, the reciprocal causal links between problem behaviors and maternal distress were investigated in 150 families containing a child with fragile X syndrome (FXS) and an unaffected sibling. Both children's behavior problems appeared to have strong, direct effects on maternal distress, but maternal distress did not appear to have any reciprocal causal effects on either child's behavior problems. Surprisingly, there were no significant differences in the effects of the two children's behavior problems on maternal distress. These data suggest that the problem behaviors of children with FXS, as well as their unaffected siblings, can have a substantial and additive impact on maternal depression and anxiety. Future research efforts should employ longitudinal research designs to confirm these findings. 相似文献

The stereotype of people who stutter is predominantly negative, holding that stutterers are excessively nervous, anxious, and reserved. The anchoring–adjustment hypothesis suggests that the stereotype of stuttering arises from a process of first anchoring the stereotype in personal feelings during times of normal speech disfluency, and then adjusting based on a rapid heuristic judgment. The current research sought to test this hypothesis, elaborating on previous research by [White, P. A., & Collins, S. R. (1984). Stereotype formation by inference: A possible explanation for the “stutterer” stereotype. Journal of Speech and Hearing Research, 27, 567–570]. Participants provided ratings of a hypothetical typical person who stutters, a person suffering from normal speech disfluency and a typical male on a 25-item semantic differential scale. Results showed a stereotype of people who stutter similar to that found in previous research. The pattern of results is consistent with the anchoring–adjustment hypothesis. Ratings of a male stutterer are very similar to a male experiencing temporary disfluency, both of which differ from ratings of a typical male. As expected, ratings of a stutterer show a small but statistically significant adjustment on several traits that makes the stereotype of stutterers less negative and less emotionally extreme than the temporarily disfluent male. Based on the results of this research, it appears that stereotype formation is a result of generalization and adjustment from personal experience during normal speech disfluency.
Educational objectives: The reader will be able to: (1) explain how the negative stereotype of people who stutter arises; (2) discuss the negative implications of stereotypes in the lives of people who stutter; and (3) summarize why the stereotype of people who stutter is so consistent and resistant to change. 相似文献

The accuracy of first impressions was examined by investigating judged construct (negative affect, positive affect, the Big five personality variables, intelligence), exposure time (5, 20, 45, 60, and 300 s), and slice location (beginning, middle, end). Three hundred and thirty four judges rated 30 targets. Accuracy was defined as the correlation between a judge’s ratings and the target’s criterion scores on the same construct. Negative affect, extraversion, conscientiousness, and intelligence were judged moderately well after 5-s exposures; however, positive affect, neuroticism, openness, and agreeableness required more exposure time to achieve similar levels of accuracy. Overall, accuracy increased with exposure time, judgments based on later segments of the 5-min interactions were more accurate, and 60 s yielded the optimal ratio between accuracy and slice length. Results suggest that accuracy of first impressions depends on the type of judgment made, amount of exposure, and temporal location of the slice of judged social behavior. 相似文献

Postevent misleading information can distort people's memories by altering and adding scenes. But can you also inhibit the retrieval of information from memory? In two studies we show that postevent information can make memory for a scene less accessible. In both studies participants first saw an event (e.g. a restaurant scene displayed in slides, or a drunk‐driving incident shown via a video clip). Later they were shown the same event without a critical scene and were told either to use this to generate a story (Experiment 1) or to imagine the event (Experiment 2). Finally they were tested. Relative to controls, this postevent omission led to fewer people reporting the critical scene in free recall and in recognition. Thus, we demonstrated that it may be possible to inhibit memories. This finding has important implications for eyewitness testimony and the recovered memory debate. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

Addressing the behavioral priorities of captive animals and the development of practical, objective measures of the value of environmental resources is a principal objective of animal welfare science. In theory, consumer demand approaches derivedfrom human microeconomics should provide validmeasures of the value of environmental resources. In practice, however, a number of empirical and theoretical problems have rendered these measures difficult to interpret in studies with animals. A common approach has been to impose a cost on access to resources and to use time with each resource as a measure of consumption to construct demand curves. This can be recorded easily by automatic means, but in a number of studies, it has been found that animals compensate for increased cost of access with longer visit time. Furthermore, direct observation of the test animals’ behavior has shown that resource interaction is more intense once the animals have overcome higher costs. As a consequence, measures based on time with the resource may underestimate resource consumption at higher access costs, and demand curves derived from these measures may not be a true reflection of the value of different resources. An alternative approach to demand curves isreservation price, which is the maximum price individual animals are prepared to pay to gain access to resources. In studies using this approach, farmed mink (Mustela vison) paid higher prices for food and swimming water than for resources such as tunnels, water bowls, pet toys, and empty compartments. This indicates that the mink placed a higher value on food and swimming water than on other resources. 相似文献
