Urban college student commuters (N = 407) were surveyed about their experiences with stress induced by driving. Of the participants 23.6% reported becoming angry at another driver more than once per day. They rated stress from other drivers as equal to the stress experienced during a college examination but gave slightly lower ratings to traffic congestion, road construction, and finding a parking place as sources of stress. Slow drivers, a child not restrained, and a vehicle following too closely were the highest rated annoying situations. Of participants, 21.6% had reported another driver to the police; nearly 22% said they carried a weapon for protection from other drivers (5.4% said a gun). Men were more than twice as likely as women to carry a weapon and three times as likely to carry a gun. Of the total sample, 19.1% feared being shot by another driver. Most participants (75.8%) said drivers were more aggressive and dangerous than they were five years ago.  相似文献

Magnitude estimations were obtained for manual assessments of pure elastic stiffness stimuli (metal springs). 20 subjects of varied experience in manual assessment of spinal stiffness volunteered to participate. The mean exponent of the power function relating perceived magnitude of elastic stiffness to measured physical magnitude was 1.65. Exponents varied across the 20 individuals but were stable across testing sessions held at least 2 weeks apart, and the size of the exponent was not related to prior experience.  相似文献

A number of studies have examined why people do or do not respond when they observe criminal activities. Traditionally, the legal system has not punished the failure to report a crime. This study sought to ascertain whether a sample of college students and public citizens thought there should be legal punishments for the failure to report crimes. Respondents (N = 301) were presented a list of illegal acts and asked to select from a list (no punishment, fine, or prison sentences) what type of punishment should be enforced for failure to report that crime. Analysis indicated that the sample thought there should be punishments for most of the crimes, with a fine as the modal response. For more serious crimes, more serious punishments were selected, and there were some sex differences. It appeared that public support for such laws might be strong.  相似文献

Under what conditions do perceivers prefer to assign a bound variable interpretation to a pronominal that is ambiguous between a bound variable and a coreferential interpretation? Several experiments were designed to test the hypothesis that language perceivers prefer a bound variable over a coreferential interpretation of a pronoun because the former only requires consultation of a logical form (LF) representation, while the latter requires access to a discourse representation. The hypothesis was disconfirmed in two respects. First, although bound variable interpretations show a processing advantage over coreferential interpretations in VP ellipsis constructions, the preference for bound variable interpretations is not general--it does not extend to other quantificational contexts. Second, the preference for bound variable interpretations in VP ellipsis constructions is not limited to examples in which the antecedent and the ellipsis site occur in the same sentence. If the bound variable advantage were due to the ready availability of the LF for the current sentence, the advantage should disappear across sentence boundaries. An alternative hypothesis is then considered which could explain the source of the bound variable advantage in VP ellipsis contexts.  相似文献

The effect of sentence priming on picture naming was investigated across the lifespan, from age 3 to 87 years. Names that are normally acquired before 3 years of age were presented in auditory contexts that were semantically congruent, incongruent, or neutral in relation to each picture and its name. Sentential priming was present at all age levels. Facilitation (neutral vs. congruent) was significantly by 4 years of age and did not vary significantly with age. Interference (incongruent vs. neutral) was significant at all age levels, but changed nonmonotonically with age (largest in the youngest children, stable from young adulthood through age 70, with a small increase in the oldest participants). We conclude that picture naming is a useful tool for the investigation of sentential priming effects across the lifespan and that it can reveal potentially interesting developmental changes in the effects of sentential context on word retrieval.  相似文献

Although feminist and community psychology share a number of epistemological and methodological perspectives that guide their respective theories and research practices, it has been argued that community psychology has not fully integrated a feminist perspective into the discipline. This paper examines how community psychology and feminist research methods might combine to help us better understand women's experiences without essentializing or universalizing those experiences. The authors offer a series of suggested directions for feminist research that may also prove promising for community psychology. Particular attention is paid to feminist social constructionist approaches insofar as they address the complex relationship between epistemology and methodology.  相似文献

Coordination often involves syntactically like categories. Based on the results of four reading time studies, it is argued here that the syntactic like-category restriction is not grammatical. Coordination of unlike categories can be just as acceptable as coordination of like categories. However, syntactically like category coordination is processed faster than coordination of unlike categories even when the two sentence types are judged to be fully acceptable. Further, parallelism of conjuncts facilitates processing regardless of whether it is parallelism in the category of the conjuncts (a property which the grammar might regulate) or parallelism in the internal structure of the conjuncts (a property which the grammar does not regulate, on anyone's view). Parallelism did not facilitate processing when the structure of a subject and object were manipulated, implying that parallelism effects are largely limited to the conjuncts of a coordinate structure and not due simply to the repetition of a phrase with a particular shape.  相似文献

Experimental rats were trained on multiple 2-odor discrimination tasks, whereas controls were given repeated sessions on Task 1 and then were tested on a novel 2-odor task. Experimental rats showed strong positive transfer across problems and approached errorless or near-errorless learning. Control rats maintained near-perfect performance on Task 1 but performed at chance on initial trials when tested with novel odors. Thus, the near-errorless terminal performance of experimental rats was a function their having been trained on multiple problems and was not simply the result of eliminating "disruptive response tendencies" (I. C. Reid & R. G. M. Morris, 1992). Results support the view that when rats are trained on a series of 2-odor discrimination tasks, they acquire a strategy or rule that allows them to solve new problems with few or no errors.  相似文献

Deep dyslexia is diagnosed when brain-injured, previously literate adults make reading errors that include hallmark semantic paralexias (e.g., reading HEART as BLOOD) and are also impaired at reading nonwords (e.g., FRIP). The diversity of these symptoms have led most researchers to conclude that there are multiple sources of impairment in this syndrome and that one of the most critical is a failure to process phonological information at a sublexical level. The patient (SD) reported in this study fits the deep dyslexia profile to the extent that she makes several semantically related reading errors. She also shows the classic frequency and image ability effects of the syndrome. However, as we report, she does read some nonwords correctly and she shows a strong advantage for naming when phonemic cues are presented. We discuss the performance of SD, on these preliminary tasks, in terms of a phonological selection impairment.  相似文献
