Language is often explained as the product of generative rules and a memorized lexicon. For example, most English verbs take a regular past tense suffix (ask-asked), which is applied to new verbs (faxed, wugged), suggesting the mental rule "add - ed to a Verb." Irregular verbs (break-broke, go-went) would be listed in memory. Alternatively, a pattern associator memory (such as a connectionist network) might record all past tense forms and generalize to new ones by similarity; irregular and regular patterns would differ only because of their different numbers of verbs. We present evidence that mental rules are indispensible. A rule concatenates a suffix to a symbol for verbs, so it does not require access to memorized verbs on their sound patterns, but applies as the "default," whenever memory access fails. We find 21 such circumstances for regular past tense formation, including novel, unusual-sounding, and rootless and headless derived words; in every case, people inflect them regularly (explaining quirks like flied out, sabre-tooths, walk-mans). Contrary to the connectionist account, these effects are not due to regular words constituting a large majority of vocabulary. The German participle -t applies to a much smaller percentage of verbs than its English counterpart, and the German plural -s applies to a small minority of nouns. But the affixes behave in the language like their English counterparts, as defaults. We corroborate this effect in two experiments eliciting ratings of participle and plural forms of novel German words. Thus default suffixation is not due to numerous regular words reinforcing a pattern in associative memory. Because default cases do not occupy a cohesive similarity space, but do correspond to the range of a symbol, they are evidence for a memory-independent, symbol-concatenating mental operation. 相似文献

Properties of auditory and visual sensory memory were compared by examining subjects' recognition performance of randomly generated binary auditory sequential frequency patterns and binary visual sequential color patterns within a forced-choice paradigm. Experiment 1 demonstrated serial-position effects in auditory and visual modalities consisting of both primacy and recency effects. Experiment 2 found that retention of auditory and visual information was remarkably similar when assessed across a 10 s interval. Experiments 3 and 4, taken together, showed that the recency effect in sensory memory is affected more by the type of response required (recognition vs. reproduction) than by the sensory modality employed. These studies suggest that auditory and visual sensory memory stores for nonverbal stimuli share similar properties with respect to serial-position effects and persistence over time. 相似文献

TELLING SOMETHING WE CAN'T KNOW: 总被引:2,自引:0,他引:2
An interpersonal verb such as annoy or admire can be categorized according to whether its grammatical subject or grammatical object initiates the interaction described by the verb Such a verb can also be categorized according to whether a derived adjective describes its grammatical subject (eg., annoying ) or its grammatical object (eg., admirable ) Although there has been much speculation (eg., Brown & Fish, 1983) that these and other characteristics of these verbs shed light on basic principles of human social interaction, we argue that research to date has failed to demonstrate directly any real-time consequences of these verbs during language comprehension. We present evidence that the initiating-reacting distinction predicts on-line changes in the accessibility of these verbs' arguments, but that the existence of a derived adjective does not. We conclude that tasks that question subjects explicitly about language may fail to reflect the ordinary processes of language comprehension 相似文献

PERCEIVED CONTINUITY OF OCCLUDED VISUAL OBJECTS 总被引:2,自引:0,他引:2

Abstract— The human visual system does not rigidly preserve the properties of the retinal image as neural signals are transmitted to higher areas of the brain Instead, it generates a representation that captures stable surface properties despite a retinal image that is often fragmented in space and time because of occlusion caused by object and observer motion The recovery of this coherent representation depends at least in part on input from an abstract representation of three-dimensional (3-D) surface layout In the two experiments reported, a stereoscopic apparent motion display was used to investigate the perceived continuity of a briefly interrupted visual object When a surface appeared in front of the object's location during the interruption, the object was more likely to be perceived as persisting through the interruption (behind an occluder) than when the surface appeared behind the object's location under otherwise identical stimulus conditions The results reveal the influence of 3-D surface-based representations even in very simple visual tasks. 相似文献

Subjects read a passage which described an interaction between a man and a woman at an office party. The woman was either sober or intoxicated, and eventually the man engaged in 1 of 3 behaviors which involved varying degrees of sexual innuendo and/or aggression: (a) verbal comment, (b) verbal request, and (c) nonverbal physical display. The results indicated that perceptions did not vary as a function of target person's intoxication in the nonverbal-display condition. On the other hand, in the verbal-comment and verbal-request conditions, subjects in the intoxicated-target-person condition perceived the initiator more favorably than subjects in the sober-target-person condition. In addition, they indicated that perceptions did not vary as a function of target-person intoxication level in the nonverbal-display condition. On the other hand, in the verbal-comment and verbal-request conditions, male subjects were more favorable toward the initiator than toward female subjects. 相似文献

We investigate the possibility that the degree to which female abuse victims are held accountable by other women who have been exposed to sexually violent mass media is primarily dependent upon 3 factors: situational relevance, personal similarity, and emotional arousal. Female subjects participated in an experiment. Factors were: film dose; film viewing/victim judgment time interval; victim-subject similarity; and situational relevance of the assault. The results showed less attribution of responsibility to similar victims and high attributions of responsibility to dissimilar victims in the personally relevant assault situation (rape). Women identified least with dissimilar rape victims and most with similar victims when they had not been desensitized. When subjects were desensitized, the defensive attribution effect failed to emerge. There was also a significant tendency among low film dose subjects to perceive more psychological injury and to attribute more distress to the victim than among high film dose subjects. 相似文献

Two patients with visual apperceptive agnosia were examined on tasks assessing the appreciation of visual material. Elementary visual functioning was relatively preserved, but they had profound difficulty recognizing and naming line drawings. More detailed evaluation revealed accurate recognition of regular geometric shapes and colors, but performance deteriorated when the shapes were made more complex visually, when multiple-choice arrays contained larger numbers of simple targets and foils, and when a mental manipulation such as a rotation was required. The recognition of letters and words was similarly compromised. Naming, recognition, and anomaly judgments of colored pictures and real objects were more accurate than similar decisions involving black-and-white line drawings. Visual imagery for shapes, letters, and objects appeared to be more accurate than visual perception of the same materials. We hypothesize that object recognition difficulty in visual apperceptive agnosia is due to two related factors: the impaired appreciation of the visual perceptual features that constitute objects, and a limitation in the cognitive resources that are available for processing demanding material within the visual modality. 相似文献
