Human social, cognitive, and linguistic functioning depends on skills for rapidly processing action. Identifying distinct acts within the dynamic motion flow is one basic component of action processing; for example, skill at segmenting action is foundational to action categorization, verb learning, and comprehension of novel action sequences. Yet little is currently known about mechanisms that may subserve action segmentation. The present research documents that adults can register statistical regularities providing clues to action segmentation. This finding provides new evidence that structural knowledge gained by mechanisms such as statistical learning can play a role in action segmentation, and highlights a striking parallel between processing of action and processing in other domains, such as language. 相似文献

Mothers (N = 168, M age = 37.0 yr., SD = 4.6) responded to a questionnaire of scales measuring sources of stress and symptoms of stress within themselves, and symptoms of stress in their 5-8-yr.-old children (61 girls, 98 boys; M age = 7.3 yr., SD = 1.0). Scores on all scales intercorrelated significantly, indicating a relationship between maternal stress and stress of the child. Both types of stress also correlated with the frequency of punishment of the child. Both maternal stress and frequency of punishment predicted stress symptoms in the children, maternal stress being a somewhat stronger predictor. 相似文献

The current study examined the persistence and phenotypic presentation of inattention/overactivity (I/O) into early adolescence,
in a sample of institution reared (IR) children adopted from Romania before the age of 43 months. Total sample comprised 144
IR and 21 non-IR Romanian adoptees, and a comparison group of 52 within-UK adoptees, assessed at ages 6 and 11 years. I/O
was rated using Rutter Scales completed by parents and teachers. I/O continued to be strongly associated with institutional
deprivation, with continuities between ages 6 and 11 outcomes. There were higher rates of deprivation-related I/O in boys
than girls, and I/O was strongly associated with conduct problems, disinhibited attachment and executive function but not
IQ more generally, independently of gender. Deprivation-related I/O shares many common features with ADHD, despite its different
etiology and putative developmental mechanisms. I/O is a persistent domain of impairment following early institutional deprivation
of 6 months or more, suggesting there may be a possible pathway to impairment through some form of neuro-developmental programming
during critical periods of early development. 相似文献

Theory of Mind (ToM) and Executive Function (EF) have been associated with autism and with attention-deficit hyperactivity
disorder (ADHD), and hence might play a role in similar syndromes found following profound early institutional deprivation.
In order to examine this possibility the current study included a group of 165 Romanian adoptees, of whom 144 were adopted
into the UK from deprived institutional settings before 43months of age, and a group of 52 within-UK adoptees, all adopted
before 6months of age. Both groups were assessed at 6 and 11years. The Strange Stories task was used to assess ToM and the
Stroop task was used to assess EF, both at age 11. The Romanian adoptees displayed deficits in both ToM and EF compared with
the within-UK adoptee group. The degree of deficit was greater for children who had experienced more than 6months of institutional
deprivation. Deficits in both domains (ToM and EF) were associated with each of the three apparently deprivation-specific
problems, namely quasi-autism, disinhibited attachment and inattention/overactivity. Statistical analyses indicated a mediating
role for both ToM and EF with respect to quasi-autism; possibly a partial mediating role for EF with respect to inattention/overactivity;
and probably no mediating role for either ToM or EF in the case of disinhibited attachment. In conclusion, there is evidence
for a possible mediating role for ToM and EF in the development of some apparently deprivation-specific difficulties in institution-reared
Romanian adoptees, but neither accounts for the overall pattern of deprivation-related difficulties. 相似文献

We examined gender differences in intergenerational family conflict and its associations with psychological and academic adjustment using a United States sample of 121 Hmong American first-year college students. Hmong women and men reported similar levels of family conflict. Family conflict was related to psychological distress, above and beyond neuroticism. Gender moderated the relationship between family conflict and substance usage and academic performance. For Hmong college men, higher family conflict was associated with lower rates of smoking and higher rates of completing the first year of college. For Hmong college women, higher family conflict was associated with greater likelihood of alcohol consumption in their lifetime. 相似文献

Here we report evidence from a new eye‐tracking measure of relational memory that suggests that 9‐month‐old infants can encode memories in terms of the relations among items, a function putatively subserved by the hippocampus. Infants learned about the association between faces that were superimposed on unique scenic backgrounds. During test trials, infants were shown three faces presented on a familiar scene. All three faces were equally familiar; however, one had been presented with the test background earlier. Visual behavior was recorded continuously using a TOBII eye tracker. Infants looked preferentially at the face that matched the test background very early in the trial; however, the time course of this preferential looking effect varied as a function of delay. These results suggest that by 9 months of age infants can form memories that represent the relations among items and maintain them over short delays. 相似文献

Can infants map meaning to newly segmented words? Statistical segmentation and word learning 总被引:3,自引:0,他引:3
The present experiments investigated how the process of statistically segmenting words from fluent speech is linked to the process of mapping meanings to words. Seventeen-month-old infants first participated in a statistical word segmentation task, which was immediately followed by an object-label-learning task. Infants presented with labels that were words in the fluent speech used in the segmentation task were able to learn the object labels. However, infants presented with labels consisting of novel syllable sequences (nonwords; Experiment 1) or familiar sequences with low internal probabilities (part-words; Experiment 2) did not learn the labels. Thus, prior segmentation opportunities, but not mere frequency of exposure, facilitated infants' learning of object labels. This work provides the first demonstration that exposure to word forms in a statistical word segmentation task facilitates subsequent word learning. 相似文献

This article reviews the position of women in the UK labour market and the increasing complexity of their employment patterns. It criticises current career theory for girls and women and examines enhancers and inhibitors of women's career development. Finally, some promising developments in theory-building for girls and women are briefly discussed, together with some implications for practice. 相似文献

Genetic testing for inherited deafness is now available within some genetics centres. This study used a structured questionnaire to assess the potential uptake of prenatal diagnosis (PND) for inherited deafness, and document the opinions of deaf and hearing individuals toward PND and termination of pregnancy (TOP) for hearing status. Participants were self-selected from the whole of the UK, of whom 644 were deaf, 143 were hard of hearing or deafened, and 527 were hearing individuals who had either a deaf parent or child. The results showed that 21% of deaf, 39% of hard of hearing and deafened, and 49% of hearing participants said they would consider PND for deafness. Six percent of deaf, 11% of hard of hearing and deafened, and 16% of hearing participants said they would consider a TOP if the fetus was found to be deaf. Two percent of deaf participants said they would prefer to have deaf children and would consider a TOP if the fetus was found to be hearing. 相似文献

Sixty‐eight 2‐ to 12‐year‐olds and 30 adults were shown colorful displays on a touchscreen monitor and trained to point to the location of a named color. Participants located targets near‐perfectly when presented with four abutting colored patches. When presented with three colored patches on a colored background, toddlers failed to locate targets in the background. Eye tracking demonstrated that the effect was partially mediated by a tendency not to fixate the background. However, the effect was abolished when the targets were named as nouns, whilst the change to nouns had little impact on eye movement patterns. Our results imply a powerful, inbuilt tendency to attend to objects, which may slow the development of color concepts and acquisition of color words.
