Words from different grammatical categories (e.g., nouns and adjectives) highlight different aspects of the same objects (e.g., object categories and object properties). Two experiments examine the acquisition of this phenomenon in 14-month-olds, asking whether infants can construe the very same set of objects (e.g., four purple animals) either as members of an object category (e.g., animals) or as embodying a salient object property (e.g., four purple things) and whether naming (with either count nouns or adjectives) influences infants' construals. Results suggest (1) that infants have begun to distinguish count nouns from adjectives, (2) that infants share with mature language-users an expectation that different grammatical forms highlight different aspects, and (3) that infants recruit these expectations when extending novel words. Further, these results suggest that an expectation linking count nouns to object categories emerges early in acquisition and supports the emergence of other word-to-world mappings.  相似文献

Faces play an important role in communication and identity recognition in social animals. Domestic dogs often respond to human facial cues, but their face processing is weakly understood. In this study, facial inversion effect (deficits in face processing when the image is turned upside down) and responses to personal familiarity were tested using eye movement tracking. A total of 23 pet dogs and eight kennel dogs were compared to establish the effects of life experiences on their scanning behavior. All dogs preferred conspecific faces and showed great interest in the eye area, suggesting that they perceived images representing faces. Dogs fixated at the upright faces as long as the inverted faces, but the eye area of upright faces gathered longer total duration and greater relative fixation duration than the eye area of inverted stimuli, regardless of the species (dog or human) shown in the image. Personally, familiar faces and eyes attracted more fixations than the strange ones, suggesting that dogs are likely to recognize conspecific and human faces in photographs. The results imply that face scanning in dogs is guided not only by the physical properties of images, but also by semantic factors. In conclusion, in a free-viewing task, dogs seem to target their fixations at naturally salient and familiar items. Facial images were generally more attractive for pet dogs than kennel dogs, but living environment did not affect conspecific preference or inversion and familiarity responses, suggesting that the basic mechanisms of face processing in dogs could be hardwired or might develop under limited exposure.  相似文献

Previous research has demonstrated that many people have misconceptions about basic properties of motion. In two experiments, we examined whether people are more likely to produce dynamically correct predictions about basic motion problems involving situations with which they are familiar, and whether solving such problems enhances performance on a subsequent abstract problem. In Experiment 1, college students were asked to predict the trajectories of objects exiting a curved tube. Subjects were more accurate on the familiar version of the problem, and there was no evidence of transfer to the abstract problem. In Experiment 2, two familiar problems were provided in an attempt to enhance subjects' tendency to extract the general structure of the problems. Once again, they gave more correct responses to the familiar problems but failed to generalize to the abstract problem. Formal physics training was associated with correct predictions for the abstract problem but was unrelated to performance on the familiar problems.  相似文献

A series of 3 studies tested the hypothesis that children's difficulty acquiring dimensional adjectives, such as big, little, tall, and short, is a consequence of how these words are used by adults. Three- and 4-year-olds were asked to compare pairs of objects drawn from a novel stimulus series using real dimension words (taller and shorter; Study 1) and novel dimension words (maller and borger; Studies 1-3). Characteristics of testing, including the presence or absence of a categorization task, were manipulated. Findings indicated that children easily acquired novel dimension words when they were used in a strictly comparative fashion but had difficulty when also exposed to the categorical form of usage. It is concluded that having to learn both categorical and comparative meanings at once may impede acquisition of dimensional adjectives.  相似文献

In a series of experiments, students were presented with selections of brief encyclopedia articles and biographical sketches, and asked to state which they preferred to read, and which they actually found to be most interesting after the reading. In all experiments, interest ratings were clearly influenced by amount of prior knowledge of the topic in question. There was in some cases a tendency to prefer less known to better known items, but more often familiar topics or persons were thought of as more interesting than unfamiliar ones. The results are compatible with the hypothesis that the inherent interestingness of a communication is directly related to its degree of perceived informativeness, and that both are dependent upon the possibility of getting to know something new about something already sufficiently well known. This study was written while the author was on sabbatical leave at the Aesthetics Research Group, University of Leicester, and was supported by a grant from the Norwegian Research Council for Science and the Humanities.  相似文献

Familiarity with an environment produces refined mental representations in adults of all ages, but it is not clear whether these representations tend to have a north-up orientation and whether familiarity facilitates the learning of new spatial information, especially in ageing. Thirty-two young and 32 older adults studied a map of their home town that included familiar and new fictitious landmarks, then performed pointing tasks, some aligned with the cardinal points south–north (SN), and others counter-aligned, north–south (NS). A measure of visuo-spatial working memory (VSWM) and a questionnaire on pleasure in exploring were also administered. The results showed that performance was better when pointing SN than NS (alignment effect), whereas pointing performance for familiar landmarks was similar for SN and NS alignments (no alignment effect). No interaction involving age was found. VSWM emerged as a significant predictor of pointing performance. Spatial mental representations of familiar environments are elaborate and flexible as regards familiar landmarks, in both young and older adults; and a familiar layout does not seem to enhance older adults' spatial memory as regards new landmarks.  相似文献

The present paper examines university graduates' beliefs about how meritocratic socioeconomic status (SES) attainment in U.S. society is for themselves (merit agency beliefs) and for most other people (merit societal beliefs), and how these distinct beliefs are differentially associated with labour market experiences and achievement‐goal attitudes and expectations in the aftermath of the Great Recession. Data from a 10‐month longitudinal study of 217 graduates from the 2013 class of a large public U.S. university were analysed using multilevel modelling. The results indicate that most participants optimistically expected to attain upward social mobility. Furthermore, participants' merit agency beliefs were reflective of their labour market prospects and experiences, and calibrated their achievement‐goal attitudes and expectations. However, participants' merit societal beliefs were not associated with these labour market experiences and achievement‐goal attitudes and expectations. The distinction between merit agency beliefs and merit societal beliefs may be motivationally beneficial by allowing individuals to continue striving toward the uncertain long‐term goal pursuit of upward social mobility despite the short‐term struggles and setbacks many young adults are likely to experience in the aftermath of the Great Recession.  相似文献

This article examined the relationship between internal working models of self and other (Bowlby, 1969) and expectations for satisfaction in a future relationship, and how that relationship is moderated by the accessibility of one's internal models. Study one showed that the model of self was predictive of expected satisfaction, but the model of other was not. In study two, the results of study one were replicated. However, using a reaction time task to measure the chronic accessibility of internal models, it was shown that the relationship between model of self and expected satisfaction existed only for people with highly accessible internal models. The implications of these findings for a more cognitive view of attachment-processes is discussed.  相似文献

Using a context discrimination procedure and rats as the subjects, the formation of context-dependent aversions to novel and familiar fluids was investigated. Experiment 1 revealed that context dependency could be established to a novel fluid (saccharin) after three cycles of context discrimination training and that the acquired context dependency was revealed also to a second familiar fluid (water) presented in the following test. Experiment 2 showed that the formation of the context-dependent aversion and its transfer to a second fluid was not affected by whether fluid presented during discrimination was novel (saccharin) or familiar (water). Experiment 3 demonstrated that when the same water was given both in the two training contexts and in the home cages of the subjects during discrimination, the context-dependent aversion formed was specific to it. These findings can be explained in terms of a simple summation effect of fluid-nausea and context-nausea associations.  相似文献

This exploratory study included 524 undergraduate students (360 women, M age = 21.1 yr., SD = 6.1; and 164 men, M age = 20.0 yr., SD = 3.6) enrolled in introductory psychology sections who completed the Empathy in Pet Dogs and Cats Scale to assess their attitudes regarding how much domestic dogs and cats show vicarious experiencing of the thoughts, feelings, or attitudes of their owners. A principal components analysis followed by varimax rotation extracted five factors accounting for 60.85% of the total variance as follows: (1) Pets' empathy for owner, (2) Cats' empathy for owner, (3) Dogs' empathy for owner, (4) Souls in humans and pets, (5) Owners' empathy for pets. Women gave significantly higher ratings than men regarding dogs' and cats' knowing when their owners are happy, sad, or angry. Women also gave significantly higher ratings than men regarding dogs' and cats' feeling love and compassion for their owners. Specific instances of empathy in pets underscore the need for contemporary research to be inclusive of operational definitions of measures of empathy.  相似文献

Although the Alternative Uses divergent thinking task has been widely used in psychometric and experimental studies of creativity, the cognitive processes underlying this task have not been examined in detail before the two studies are reported here. In Experiment 1, a verbal protocol analysis study of the Alternative Uses task was carried out with a Think aloud group (N = 40) and a Silent control group (N = 64). The groups did not differ in fluency or novelty of idea production indicating no verbal overshadowing. Analysis of protocols from the Think aloud group suggested that initial responses were based on a strategy of Retrieval from long‐term memory of pre‐known uses. Later responses tended to be based on a small number of other strategies: property‐use generation, imagined Disassembly of the target object into components and scanning of Broad Use categories for possible uses of the target item. Novelty of uses was particularly associated with the Disassembly strategy. Experiment 2 (N = 103) addressed the role of executive processes in generating new and previously known uses by examining individual differences in category fluency, letter fluency and divergent task performance. After completing the task, participants were asked to indicate which of their responses were new for them. It was predicted and found in regression analyses that letter fluency (an executively loading task) was related to production of ‘new’ uses and category fluency was related to production of ‘old’ uses but not vice versa.  相似文献

We examined electrophysiological correlates of conscious change detection versus change blindness for equivalent displays. Observers had to detect any changes, across a visual interruption, between a pair of successive displays. Each display comprised grey circles on a background of alternate black and white stripes. Foreground changes arose when light-grey circles turned dark-grey and vice-versa. Physically stronger background changes arose when all black stripes turned white and vice-versa. Despite their physical strength, background changes were undetected unless attention was directed to them, whereas foreground changes were invariably seen. Event-related potentials revealed that the P300 component was suppressed for unseen background changes, as compared with the same changes when seen. This effect arose first over frontal sites, and then spread to parietal sites. These results extend recent fMRI findings that fronto-parietal activation is associated with conscious visual change detection, to reveal the timing of these neural correlates.  相似文献

The use of multiple familiar views of objects to facilitate recognition of novel views has been addressed in a number of behavioral studies, but the results have not been conclusive. The present study was a comprehensive examination of view combination for different types of novel views (internal or external to the studied views) and different objects (amoeboid objects and objects composed of geons; objects with and without self-occlusion across rotation). The authors found that the advantage gained from the study of 2 views was more than the generalization from each of the studied views presented alone. This facilitation occurred only for internal views but not external views. In addition, the benefits from the study of 2 views diminished when (a) the studied views did not share the same visible features and when (b) the studied views were separated by a small angular difference.  相似文献

Siblings shape each other's attitudes and behaviors during childhood and adolescence; however, it is less clear if siblings continue to influence each other in emerging adulthood. This study investigated the extent to which emerging adults modeled their siblings in domains of adulthood attainment. Participants included 1,750 emerging adults from the United States between the ages of 18 and 29 years. Data were collected via Amazon Mechanical Turk. Findings showed that perceptions of siblings' adulthood attainment were positively related to emerging adults' development in those same domains. Moreover, the extent to which emerging adults modeled their siblings enhanced these associations; neither birth order nor gender composition moderated these findings. In short, processes of sibling influence continue to be relevant in emerging adulthood.  相似文献

In a series of experiments, a negative priming paradigm was used to determine how the visual system represents novel shapes under conditions of inattention. Observers in a shape-matching task viewed overlapping shapes with or without surface segmentation cues. Positive priming occurred with opaque and transparent surface-like shapes, whereas negative priming was found with outlined and transparent shapes that lacked surface segmentation cues. This effect generalized to familiar shapes. These results support the importance of segmentation cues in negative priming and suggest that, under otherwise identical conditions, surface segmentation processes can determine whether positive or negative priming occurs in an implicit memory task. Thus, selective attention for overlapping shapes may be best understood in relation to surface segmentation processes.  相似文献

Research over the past 20 years has revealed that even very young infants possess expectations about physical events, and that these expectations undergo significant developments during the first year of life. In this article, I first review some of this research, focusing on infants' expectations about occlusion, containment, and covering events, all of which involve hidden objects. Next, I present an account of infants' physical reasoning that integrates these various findings, and describe new experiments that test predictions from this account. Finally, because all of the research I discuss uses the violation-of-expectation method, I address recent concerns about this method and summarize new findings that help alleviate these concerns.  相似文献

Trauma survivors include individuals who have been affected by a severe physical or psychologically threatening experience. This study compared the expectations for career counseling and the level of career maturity among trauma survivors and nonsurvivors (individuals who have had no trauma experience) who participated in a program at a midwestern social service agency. The findings indicated that trauma survivors were more motivated and open to counseling than nonsurvivors, but expected their counselors to be less empathic. No significant differences were noted on career maturity. Implications for counselor training and future research are also discussed.  相似文献
