In a series of experiments we tested 4- and 8-month-olds’ ability to represent the spatial layout of an object across changes in its orientation with respect to egocentric spatial coordinates. A fixed-trial familiarization procedure based on visual habituation behaviour shows that both age groups are able to discriminate between different object-centred spatial configurations. Furthermore, both age groups demonstrate the ability to make discriminations of object-centred spatial coordinates that require simultaneous reference to at least two spatial axes of the object. We discuss these findings in relation to theories of the early development of object recognition and spatial reference skills. 相似文献

ABSTRACT Difficulties in executive processes can disturb daily life functioning. Using data obtained from two independent community-dwelling samples (n 1?=?468, n 2?=?669, 18–97 years), we examined the factor structure of the Dysexecutive Functioning Questionnaire (DEX) and explored the frequencies and potential correlates of self-reported executive difficulties. Our results revealed that executive problems are parsimoniously described with one underlying factor. Everyday executive dysfunctions were moderately frequent throughout adulthood. Reports of executive problems were associated with individual difference characteristics including age, subjective health, personality, affect, and cognition. We also found that, although executive functions are known to decline with advancing adult age, younger age groups reported more problems than older groups, an effect that was partially mediated by a negative affect factor. We discuss implications for the validity of the instrument as well as directions for future research on executive functioning difficulties in everyday life. 相似文献

Methods of coping with frustration were examined in handicapped and nonhandicapped children at three different age levels, by means of the Rosenzweig P-F Study. While an extrapunitive approach was predominant in both groups and did not differ between the groups, significant differences were found in the use of secondary coping strategies. When compared with nonhandicapped counterparts, handicapped six year olds were more likely to minimize or deny frustration. At 10 years, handicapped Ss were more likely than nonhandicapped Ss to be intropunitive or self-blaming. There was a developmental tendency for handicapped Ss to make greater use of intropunitive responses with increasing age. 相似文献

This paper reports two experiments concerned with the interaction of response and target factors in a coincident timing situation. Coincident timing involves executing a response to intercept a moving target. The target response relationship was manipulated in the first experiment by providing some targets with no structure (linear path) and others containing 1 and 2 bounce points. In the second experiment, responses required 0, 1, or 2 reversals in direction. The results provide tentative support for the notion that structure in the target path could be linked to the key temporal response dynamics for improved performance consistency, and that subjects may alter their response structure to incorporate this linkage. This can be further extended to the advantage of simply moving while perceiving movement. This paper stresses the importance of examining the perceptual and motor requirements of the coincident timing skill in unison. 相似文献

This study investigated the role of trust beliefs (i.e., trustworthiness, trustfulness) on aggression trajectories in a four-wave longitudinal study using an ethnically diverse sample of 8- to 11-year-old children (N?=?1,028), as well as the risk profiles of low trust beliefs and low socioeconomic status on aggression trajectories. At Time 1 to Time 4, teachers provided ratings of overt aggressive behavior. At Time 1, children’s trust beliefs were assessed by a sociometric peer nomination instrument and derived using social relations analysis. Latent growth curve analysis revealed five trajectories of aggressive behavior: high-stable, medium-stable, low-stable, increasing, and decreasing. As hypothesized, children in the high-stable trajectory were perceived as less trustworthy than children in the low-stable, medium-stable, and increasing trajectories. Children in the high-stable trajectory were less trustful than children in the low-stable trajectory and had a significantly higher risk profile (i.e., low trust beliefs and low SES) compared to children in the low-stable trajectory. Our findings indicate that the developmental course of aggression during middle childhood is predicted by children’s trustworthiness and trustfulness. A risk profile of low trust and low socioeconomic status contributes to high-stable aggression trajectories. 相似文献

The International Intrusive Thought Interview Schedule (IITIS) was used to assess and compare the unwanted intrusive thoughts (UITs) reported in a group of patients with obsessive compulsive disorder (OCD) and a non-clinical group. Although all participants reported at least one type of intrusion, OCD patients experienced more intrusive thoughts than non-clinical participants, and this difference was statistically significant. In the OCD group, intrusive thoughts were more frequent, interfered more with daily life, were considered to be more important to get out of the mind, and were more difficult to stop than in non-clinical participants. The two groups did not differ significantly in terms of five appraisals of the most distressing intrusive thought. One appraisal (importance) was used far more by the OCD group than the non-clinical group. For three appraisals (intolerance of anxiety, need to control, and intolerance of uncertainty), the difference was smaller. Only two of the strategies for controlling the most upsetting intrusive thought (ritual and avoidance) were of value in differentiating between the two groups. The IITIS (an instrument used to assess intrusions in non-clinical samples) appears to be of value for the assessment of patients with OCD. 相似文献

This paper proposes a theory of subjective expected utility based on primitives only involving the fact that an act can be judged either “attractive” or “unattractive”. We give conditions implying that there are a utility function on the set of consequences and a probability distribution on the set of states such that attractive acts have a subjective expected utility above some threshold. The numerical representation that is obtained has strong uniqueness properties. 相似文献

This study examined competing substantive hypotheses about dynamic (i.e., time-ordered) links between memory and functional limitations in old age. We applied the Bivariate Dual Change Score Model to 13-year longitudinal data from the Asset and Health Dynamics Among the Oldest Old Study (AHEAD; N = 6,990; ages 70 - 95). Results revealed that better memory predicted shallower increases in functional limitations. Little evidence was found for the opposite direction that functional limitations predict ensuing changes in memory. Spline models indicated that dynamic associations between memory and functional limitations were substantively similar between participants aged 70-79 and those aged 80-95. Potential covariates (gender, education, health conditions, and depressive symptoms) did not account for these differential lead-lag associations. Applying a multivariate approach, our results suggest that late-life developments in two key components of successful aging are intrinsically interrelated. Our discussion focuses on possible mechanisms why cognitive functioning may serve as a source of age-related changes in health both among the young-old and the old-old. 相似文献
