Young maltreated children, birth to three years, represent the age group with the highest rates of maltreatment in the United
States (ACYF 2007). There are few studies to date that have investigated early childhood maltreatment and its effects on emotion
regulatory processes and psychopathology. In response, the current investigation uses a dyadic assessment procedure to examine
the relationship between parenting, emotion regulation, and symptoms of psychopathology among maltreating and non-maltreating
parent–child interactions. The participants in this study were 123 children (66 maltreated and 57 nonmaltreated) from ages
1–3. Child and parent affect and child effortful control were observed during a parent–child interaction task. Symptoms of
psychopathology were measured using the Child Behavior Checklist. The maltreated children exhibited more anger, more internalizing
symptomatology, and less positive affect compared to non-maltreated children. Among maltreated children, emotion dysregulation
was associated with internalizing symptomatology. Moreover, these data reveal parental positive affect was associated with
lower child internalizing symptomatology and parental anger was associated with higher child internalizing symptomatology
in the entire sample. This investigation offers evidence that emotion dysregulation subsequent to poor dyadic interactions
is associated with early child maltreatment. These data suggest that maltreated children experience difficulties in emotion
regulation which may be related to their higher levels of behavioral symptomatology. 相似文献

Five word-spotting experiments explored the role of consonantal and vocalic phonotactic cues in the segmentation of spoken Italian. The first set of experiments tested listeners' sensitivity to phonotactic constraints cueing syllable boundaries. Participants were slower in spotting words in nonsense strings when target onsets were misaligned (e.g., lago in ri.blago) than when they were aligned (e.g., lago in rin.lago) with phonotactically determined syllabic boundaries. This effect held also for sequences that occur only word-medially (e.g., /tl/ in ri.tlago), and competition effects could not account for the disadvantage in the misaligned condition. Similarly, target detections were slower when their offsets were misaligned (e.g., cittá in cittáu.ba) than when they were aligned (e.g., cittá in cittá.oba) with a phonotactic syllabic boundary. The second set of experiments tested listeners' sensitivity to phonotactic cues, which specifically signal lexical (and not just syllable) boundaries. Results corroborate the role of syllabic information in speech segmentation and suggest that Italian listeners make little use of additional phonotactic information that specifically cues word boundaries. 相似文献

Three experiments were performed in an attempt to achieve a better understanding of the effect of dopamine on handwriting. In the first experiment, kinematic aspects of handwriting movements were compared between healthy participants and patients with Parkinson's disease (PD) on their usual dopaminergic treatment and following withdrawal of dopaminergic medication. In the second experiment, the writing performance of healthy participants with a hyperechogenicity of the substantia nigra as detected by transcranial sonography (TCS) was compared with the performance of healthy participants with low echogenicity of the substantia nigra. The third experiment examined the effect of central dopamine reduction on kinematic aspects of handwriting movements in healthy adults using acute phenylalanine and tyrosine depletion (APTD). A digitising tablet was used for the assessment of handwriting movements. Participants were asked to perform a simple writing task. Movement time, distance, velocity, acceleration and measures of fluency of handwriting movements were measured. The kinematic analysis of handwriting movements revealed that alterations of central dopaminergic neurotransmission adversely affect movement execution during handwriting. In comparison to the automatic processing of handwriting movements displayed by control participants, participants with an altered dopaminergic neurotransmission shifted from an automatic to a controlled processing of movement execution. Central dopamine appears to be of particular importance with regard to the automatic execution of well-learned movements. 相似文献

In this paper we suggest the potential clinical usefulness of two projective tests (Rorschach and Object Relation Technique) and of a clinical interview focused on the pathway to suicide, life events, and major life difficulties to better define subtypes of patients attempting suicide. Thirty-three hospitalized subjects who had attempted suicide in the previous 6 months were examined using an in-depth assessment of the pathway to suicide. The aims of this study were: (1) to compare, within a clinical sample of suicidal attempters, the psychopathological, personality, and psychosocial characteristics of subjects with mood disorders alone, personality disorders and dysfunctional personality alone, and mood disorders with personality disorders and/or dysfunctional personality; and (2) to analyze the relationship between the method chosen and the clinical characteristics of the subgroups. 相似文献

Prefrontal functions subserve inhibition control for retrieval of semantically related items inducing forgetting 19 a-MCI patients and 29 controls underwent neuropsychological evaluation and retrieval-practice paradigm (RPP) to estimate baseline remember (BR), retrieval-induced facilitation (FAC) and retrieval-induced forgetting (RIF). A-MCI patients underwent also 3 T-MRI to assess relationship between regional grey matter (rGM) volumes and RPP indexes Behaviourally, RIF and FAC were both observed controls, while RIF only was observed in a-MCI patients. In patients but not in controls, RIF was associated with cognitive efficiency and FAC with memory performance. Patients showed also associations between BR and rGM volumes in the precuneus, no association was found between rGM volumes and RIF and FAC. A-MCI patients did not benefit from repeated practice during retrieval of studied items, which is likely due to their memory disorder. In contrast, patient cognitive efficiency would drive retrieval suppression of interfering stimuli. 相似文献

Intellectual abilities display high heterogeneity in patients with schizophrenia that might depend on the interaction among neurodevelopmental processes, environmental factors and neurocognitive decline. This study aimed to disentangle the interplay between intellectual level, cognitive status and each cognitive domain, with a focus on speed-related abilities, also including pre-morbid factors. In details, by means of cluster analysis, we identified both in global sample of 452 patients affected by schizophrenia and in a subsample with high pre-morbid functioning, different profiles based on current intellectual level and global cognitive status, analysing the distribution of deficits in each cognitive domains between groups. Then, through regression models, we analysed the contribution of speed-related domains and global cognitive profile to each other cognitive function. Considering the whole sample, results highlight three groups (high, medium and low cognitive level), while among patients with high pre-morbid level, the heterogeneity was best captured by two groups (high and medium level). Still, within each group, a small to high percentage of patients achieved normal score in neurocognitive abilities depending on the cluster they belong to. Speed of processing and psychomotor coordination resulted impaired in all clusters, even in patients with high pre-morbid functioning. The regression analyses revealed significant effects of both cognitive profile and speed-dependent domains on the other cognitive abilities. This study confirms, in a large sample, previous data about the heterogeneity of intellectual and neurocognitive functioning in schizophrenia and highlights the main role of speed-dependent neurocognitive functioning, also as an important target of rehabilitation. 相似文献

Many animals use spatial memory. Although much work has examined the accuracy of spatial memory, few studies have explicitly
focused on its longevity. The importance of long-term spatial memory for foraging has been demonstrated in several cases.
However, the importance of such long-term memory for all animals is unclear. In this study, we present the first evidence
that a parid species (the black-capped chickadee, Poecile atricapillus) can remember the location of a single food item for at least 6 months under an associative-learning spatial memory paradigm
with multiple reinforcements. We did not detect a significant difference in memory longevity between two populations of chickadees
shown previously to differ in short-term spatial memory and hippocampal morphology, an area of the brain involved in spatial
memory. Our study showed that small birds such as parids can maintain spatial memories for long periods, a feat shown previously
only in corvids. Moreover, we were able to demonstrate this longevity within the context of only 16 repeated trials. We speculate
that this ability may potentially be useful in relocating caches if reinforced by repeated visits. Future studies are necessary
to test whether our results were specifically due to multiple reinforcements of the food-containing location and whether parids
may have similar memory longevity during food-caching experiences in the wild. 相似文献

Minimally conscious state (MCS) is a condition of severely altered consciousness, in which patients appear to be wakeful and exhibit fluctuating but reproducible signs of awareness. MCS patients do not respond and are therefore dependent on others. In agreement with the embodied cognition assumption that motor actions influence our cognition, the absence of movement and the decrease in consequences for any type of covert or overt response may cause an extinction of goal-directed thinking. Brain-computer interfaces, which allow a direct output without muscular involvement, may be used to promote goal-directed thinking by allowing the performance of spatial and motor imagery tasks and could facilitate the interaction of MCS patients with their environment, possibly regaining some degree of communication and autonomy. 相似文献

There is a general consensus that Internet addiction (IA) is mainly related to social aspects of the Web, especially among adolescents. The empirical link between poor social skills and IA is well documented; however, theoretical explanations for this relationship are less developed. One possibility is that people with poor social skills are especially prone to develop a preference for online social interaction (POSI), which, in turn, predicts problematic usage. This hypothesis has been tested for loneliness and social anxiety, but not for self-esteem (SE; one of the main antecedents of IA). Furthermore, the mediating role of the perceived relevance of some Internet features (e.g., anonymity) in the relationship between SE and POSI has never been investigated. A cross-sectional study was conducted with 257 adolescents. Using mediation analyses, we found evidence among females for the mediating role of (a) POSI in the relationship between SE and IA, and (b) the subjective relevance of some Internet features in the association between SE and POSI. No significant effects were found for males. 相似文献
