Two experiments are described in which it was investigated whether the adaptation on which motion aftereffects (MAEs) are based is a response to retinal image motion alone or to the motion signal derived from the process which combines the image motion signal with information about eye movement (corollary discharge). In both experiments observers either fixated a stationary point or tracked a vertically moving point while a pattern (in experiment 1, a grating; in experiment 2, a random-dot pattern) drifted horizontally across the field. In the tracking condition the adapting retinal motion was oblique. In the fixation condition it was horizontal. In every case in both conditions the MAE was horizontal, in the direction opposite to that of pattern motion. These results are consistent with the hypothesis that the adaptation is a response to the motion signal derived from the comparison of eye and image motion rather than to retinal motion per se. An alternative explanation is discussed. 相似文献

The present study suggests a method with which to assess the interrelations between different types of pretend play. In contrast to standard methods in this area, the various types of pretend play were measured within an interactive play scenario. The pretend play tasks were included in a semi‐structured play sequence and presented to young children between 24 and 30 months of age (N=30). Self‐ and doll‐directed pretence, object substitution, pretence with realistic objects, and self‐initiated pretend play, as well as the understanding that an object had been given two identities was tested. The capacity for dual representation was assessed by asking for the real and pretend identity of an object. Age differences were found in the overall score for elicited pretence but not for all items separately. Individual items also differed in difficulty and thus are of potential use for assessing intraindividual differences in pretend play. Findings are discussed in the context of current theories and methods concerning the development and assessment of pretend play. 相似文献

In a series of three experiments, we explored the nature of implicit representations in change blindness (CB). Using 3 x 3 letter arrays, we asked subjects (Ss) to locate changes in paired arrays separated by 80 ms ISIs, in which one, two or three letters of a row in the second array changed. In one testing version, a tone followed the second array, signaling a row for partial report (PR). In the other version, no PR was required. After Ss reported whether a change had been detected and the PR had been completed (if required), they were asked to identify a degraded letter trigram that was either novel, or from a previously shown row (repetition priming). Our findings indicate that when CB occurs, both the pre-change and post-change stimulus information primes despite its unavailability to consciousness. Surprisingly, findings also indicate that when change detection occurs only the post-change information primes. 相似文献

This essay critically examines three theories of moral rights, theBenefit, the Interest, and the Choice theories. The Interest andChoice theories attempt to explain how rights can be more robustthan seems possible on the Benefit theory. In particular, moralrights are supposed to be resistant to trade-offs to supportprincipled anti-paternalism, to constitute a distinct dimensionof morality, and to provide right holders with a range ofdiscretionary choice. I argue that these and other featuresare better yet provided by a fourth theory of moral rights, theJurisdiction theory. 相似文献

A policy-capturing study was conducted to evaluate the roles of both plaintiff and defendant race and gender on judgments of criminal guilt in either an assault or a theti case. It was hypothesized that defendant gender and race would affect likelihood of guilt ratings. Moreover, mock jurors' dispositional happiness, scores of modern racism, and race and gender were explored as potential influences on their decision-making policies and judgments. As predicted, strong support was found for the role of defendant gender on judgments of guilt. However, defendant race did not significantly impact guilt ratings. Post hoc analses revealed the importance of race and gender of the victim to juror decisions. In addition, participants' own race and gender played signiticant roles in the decisionmaking policies that were produced. Limitations of the study are discussed. as are topics for future research. 相似文献

This study evaluated the reliability and validity of the Cleveland Scale for Activities of Daily Living (CSADL), a scale designed to measure in detail specific activities of daily living in individuals with dementia. Administered to knowledgeable informants by trained examiners, the CSADL demonstrated good reliability in terms of interrater agreement and internal consistency. The validity of CSADL total scores was shown by its sensitivity to degree of cognitive impairment: All comparisons between means of the healthy elderly group and three groups of AD patients differing in severity were statistically significant. The CSADL was highly correlated with the Blessed–Roth Dementia Scale (DS-ADL) and more highly correlated with Mini-Mental State Exam scores than was the DS-ADL. 相似文献

The dimensional change card-sorting task (DCCS) is used to assess the executive abilities of young children. Typically, 3-year-olds have difficulty in performing this task. However, the exact nature of this difficulty is still being debated. In the standard DCCS, children need to sort, for example, test cards with a blue flower or a red car into two boxes marked with the target cards. The 3-year-olds commonly have pronounced difficulty in switching from one sorting criterion (e.g., color) to another (e.g., shape). Here two experiments with 3-year-olds showed that making the transition between the sorting criteria more distinct improved performance significantly. This was achieved by taking away the target cards for a brief time period, asking a question irrelevant to the task, and pretraining the children by redescribing the test cards. 相似文献

The present study examined potential gender differences in the effects of family structure and family processes on externalizing and internalizing behavioral outcomes among youth over time. Using data from waves one through three of the Add Health study, results indicated that the relationship between family structure and family processes on behavioral outcomes varied depending on the specific externalizing or internalizing behavior. Family structure directly influenced three different externalizing behaviors, but indirectly influenced internalizing behaviors through its effect on maternal attachment and to some degree parental permissiveness. The long-term influence of family structure, family processes, and later externalizing and internalizing behaviors is complex. These relationships played out similarly across both male and female youth, suggesting that the effect of living in a single-parent home, subsequent family processes, and individual behavior and well-being may not be different across gender. 相似文献
