Children begin to use methods of concealment to achieve interpersonal goals at an early age, and the ability to conceal information requires cognitive skills to be effective. Despite research on children's lie telling, there is little known about the “spectrum” of concealment methods that children use, which can range from full disclosures to active concealment through the use of deception. This study focused on children's use of concealment methods in a prosocial situation, in relation to their cognitive ability. Children aged 4–11 years ( N = 106) completed several cognitive activities that measured theory of mind (ToM), working memory, and inhibitory control with an experimenter and created a surprise gift for a parent. After the activities were complete, children were told to keep the surprise gift a secret until it was ready, then they were sent back to their parents, who questioned them about their activities. Children were coded based on their concealment behavior (full disclosers, partial concealers, passive concealers, and active concealers) in response to their parents’ questions. A discriminant function analysis indicated that age and children's cognitive scores (first‐order ToM, second‐order ToM, and working memory) differentiated between children who disclosed the secret about the surprise gift and children who used partial‐to‐active concealment methods to keep the secret. Results suggest that younger children, and children with lower ToM and working memory were more likely to disclose the secret. Findings suggest that children employ various methods of concealment to keep a prosocial secret from a parent and that higher cognitive ability is associated with the tendency to use concealment methods in social interactions. 相似文献

PURPOSE: The degree to which depression interacts with the cognitive deficits of epilepsy to alter cognitive skill and general functioning is unknown. Depression has significant negative effects on adaptive functioning including cognitive skills. Temporal lobe epilepsy (TLE) patients are known to possess cognitive dysfunction. Thus, TLE patients who are depressed may suffer a double burden of cognitive deficits. METHODS: We examined whether depressed patients show increased cognitive deficits relative to nondepressed TLE patients (n = 59). We then sought to determine if this effect varied for left versus right TLE patients utilizing preoperative depression and neuropsychological data. To accurately study the lateralization of any observed effects, we selected only patients with definitive evidence of unilateral pathology and seizure focus and utilized a two-year seizure-free postsurgical outcome to capture this. RESULTS: The data suggested that cognitive performance was not related to depression, and that depression did not reliably mediate the cognitive presentation of either our left or right TL patients. The notion of a double burden on cognition did not receive support from our data. The data did produce the expected advantage on verbal memory measures for right TLE patients. CONCLUSIONS: The reasons for the limited statistical effects are discussed and issues in unraveling the causal relationships between depression, cognition, and TLE are considered. We discussed the potential role depression may play in the cognitive skills of TLE patients, but the major implication is that depression and neurocognitive performance appear to bear a limited relationship in the context of TLE. 相似文献

PURPOSE: The association of self-reported subclinical depressive symptoms and negative mood states with cognitive functioning was evaluated in 51 consecutive newly diagnosed adult persons with epilepsy. METHODS: Emotional state was assessed with Profile of Mood States (POMS) and Brief Depression Scale (BDS) and was correlated with a battery of neuropsychological tests. RESULTS: Patients with epilepsy reported more depressive symptoms in BDS than in controls. They also had more feeling of bewilderment and less vigor on POMS. Higher scores in BDS and in POMS inefficiency scale were associated with slower nondominant hand tapping, but emotional state did not correlate with cognitive measures within the epilepsy group. CONCLUSIONS: Self-reported symptoms of depression and negative mood states were not extensively or significantly associated with cognitive function, and they do not explain the cognitive impairments observed in cognition in newly diagnosed patients with epilepsy. 相似文献

ASD symptomology and behavioral problems pose challenges for children with ASD in school. Disagreement between parents and teachers in ratings of children’s behavior problems may provide clinically relevant information. We examined parent–teacher disagreement on ratings of behavior problems among children with ASD during the fall and spring of the school year. When child, teacher, and class characteristics were considered simultaneously, only ASD symptom severity predicted informant disagreement on internalizing and externalizing behavior problems. We also examined associations between informant disagreement and parent school involvement. Cross-lagged panel analyses revealed that higher informant disagreement on children’s behavior problems in the fall predicted lower parent school involvement in the spring, suggesting that greater informant agreement may foster parental school involvement over time. 相似文献

Parents of 125 children, adolescents and young adults with autism spectrum disorders completed a newly developed questionnaire aimed at identifying cognitive and behavioural characteristics associated with savant skills in this group. Factors distinguishing skilled individuals were then further investigated in case studies of three individuals with exceptional skills for music, art and mathematics. The findings from the case studies largely confirmed the results from the questionnaire study in showing that special skills are associated with superior working memory and highly focused attention that is not associated with increased obsessesionality. Although intellectual impairment and a local bias have been widely associated with special skills in the savant literature, neither the screening nor case studies provided strong evidence for such associations. 相似文献

BackgroundOptimism and cynical hostility independently predict morbidity and mortality in Women’s Health Initiative (WHI) participants and are associated with current smoking. However, their association with smoking cessation in older women is unknown.PurposeThe purpose of this study is to test whether optimism (positive future expectations) or cynical hostility (mistrust of others) predicts smoking cessation in older women.MethodsSelf-reported smoking status was assessed at years 1, 3, and 6 after study entry for WHI baseline smokers who were not missing optimism or cynical hostility scores (n = 10,242). Questionnaires at study entry assessed optimism (Life Orientation Test-Revised) and cynical hostility (Cook-Medley, cynical hostility subscale). Generalized linear mixed models adjusted for sociodemographics, lifestyle factors, and medical and psychosocial characteristics including depressive symptoms.ResultsAfter full covariate adjustment, optimism was not related to smoking cessation. Each 1-point increase in baseline cynical hostility score was associated with 5% lower odds of cessation over 6 years (OR = 0.95, CI = 0.92–0.98, p = 0.0017).ConclusionsIn aging postmenopausal women, greater cynical hostility predicts lower smoking cessation over time. Future studies should examine whether individuals with this trait may benefit from more intensive cessation resources or whether attempting to mitigate cynical hostility itself may aid smoking cessation. 相似文献

This study sought to appraise internationally published literature investigating bullying in its association with deliberate self-harm (DSH). A systematic review and series of meta-analyses using random effects models were conducted. A total of 68 effect sizes, analyzing data from 156,284 adolescents aged 11–19 years were examined. Results showed significant associations between both traditional bullying perpetration (OR 1.81, 95% CI [1.33, 2.47], p?.0001) and victimization (OR 2.34, 95% CI [1.89, 2.89], p?.0001) and DSH. Cyber-bullying victimization (OR 3.55, 95% CI [2.71, 4.65], p?.0001) and the co-occurrence of traditional and cyber-bullying victimization (OR 3.39, 95% CI [1.56, 7.37], p?=?.002) were also associated with DSH. Moderator analyses showed variation in results based on methodological- and sample-level variables. Findings suggested that exposure to bullying, either as perpetrators or victims, poses risks for DSH. 相似文献

This study examined associations between childhood callous-unemotional (CU) traits and cognitive control using a conflict adaptation paradigm. Participants were ( N = 158) children aged 9 to 12 years ( M = 10.42, SD = 1.05; 57 % boys), who completed a modified color-word Stroop task. CU traits and conduct problems were indexed via self-reports on the Strengths and Difficulties Questionnaire and the Inventory of Callous-Unemotional Traits. CU traits were found to be uniquely associated with reduced conflict adaptation, however, this significant association was specific to boys. Conversely, conduct problems were associated with increased conflict adaptation, but among girls only. These findings contribute to evidence of atypical goal directed behavior in boys with CU traits by providing preliminary evidence that the specific impairments in cognitive control that characterize these boys include those concerning dynamic adjustments in cognitive control. Findings are discussed in relation to accounts of childhood CU traits based on the Response Modulation hypothesis. 相似文献

Previous studies have indicated that preterm birth and low birth weight are associated with structural brain abnormalities and neurocognitive deficits in childhood and adolescence, although very few studies have included follow-up in adulthood. Here we assessed the effect of preterm delivery (524 subjects; mean 34.6 weeks, S.D. = 1.7) or low birth weight (366 subjects; mean 2159 g, S.D. = 303) on educational and occupational outcomes at age 31 years in the Northern Finland 1966 Birth Cohort, along with 10,132 term, normal birth weight control subjects. Cognitive tests and brain morphology using magnetic resonance imaging were assessed at age 33-35 years in a subset of the cohort (9 subjects; 95 controls). The preterm or low birth weight subjects had slightly lower school ratings and lower educational levels in adulthood, and they performed worse in verbal learning. The low birth weight subjects were less likely to be employed. There were no mean differences in the magnetic resonance imaging tissue segmentation analysis of the brain. In conclusion, although there were no overall changes in brain morphology in the preterm or low birth weight group, there was evidence for slightly poorer educational and occupational careers and cognitive capacity, which may reflect functional disruption not evident in structure. 相似文献

Recent research has yielded increasing support for neurobiologic theories of autism. A number of family and twin studies support the role of genetics and have led to wide acceptance of autism as an organically based disorder. Controversy persists, however, over the role of congenital medical conditions in the etiology of autism. Two rather divergent views have emerged. One, advocated by Gillberg and colleagues, proposes that up to 30% of cases of autism are associated with a known medical condition. On the other hand, research by Rutter and colleagues suggests the incidence may be closer to 10%. In this retrospective study records on 211 subjects with autism and other developmental disorders are reviewed to determine the prevalence of associated medical conditions and its variability related to the system used to diagnose autism. Results suggest the prevalence of medical conditions with suspected etiologic relationship with autism varies between 10 and 15%, depending on the diagnostic system employed. Further variability in prevalence rates results from a less strict definition of medical condition and yields rates between 25 and 37%. Disparate findings in previous research may stem from variability in both diagnostic system employed and which medical conditions are considered significant in the etiology of autism. 相似文献

Generalized anxiety and depression symptoms may be associated with poorer social outcomes among children with Autism Spectrum Disorder (ASD) without intellectual disability. The goal of this study was to examine whether generalized anxiety and depression symptoms were associated with social competence after accounting for IQ, age, and gender in typically developing children and in children with ASD. Results indicated that for the TD group, generalized anxiety and depression accounted for 38% of the variance in social competence and for children with ASD, they accounted for 29% of the variance in social competence. However, only depression accounted for a significant amount of the variance. The findings underscore the importance of assessing the social impact of internalizing symptoms in children with ASD. 相似文献

Cognitive impairment is one of the core symptoms in schizophrenia, which reflects the neurodevelopmental deficits in the etiology of this disease. Brain-derived neurotrophic factor (BDNF) plays an important role in various neurodevelopmental processes. Growing evidence has shown that BDNF may be involved in the etiology of schizophrenia. The aim of this study was to examine the association of the BDNF Val66Met polymorphism with cognition in patients with schizophrenia. Various neuropsychological tests including the Wechsler Adult Intelligence Scale-Revised, the Wechsler Memory Scale-Revised, and the Wisconsin Card Sorting Test (WCST) were employed in a sample of 112 antipsychotic-na?ve patients with schizophrenia and 63 healthy controls. We examined the Val66Met polymorphism in the 112 patients and 394 controls. Among the patients, cognition was compared between Met allele carriers and non-Met allele carriers. A wide range of cognitive deficits were demonstrated in the schizophrenic patients, compared with the controls (Ps?0.01). No significant differences of genotype or allele distribution were identified between patients and controls. The patients with Met allele showed more percent WCST perseverative errors than those without Met allele (P?=?0.007). After stratification based on gender, an association between the Met allele and a higher percentage of perseverative errors was found in male patients (P?=?0.014), but not in females (P?=?0.09). Cognitive performance is broadly impaired in schizophrenic patients. The BDNF Val66Met polymorphism may be involved in the impaired executive function. This effect may have gender-specific characteristics. 相似文献

The validity of neuropsychological testing is reliant on examinees putting forth adequate effort, yet it has been asserted that verbal subtests from the Wechsler Adult Intelligence Scales (WAIS) are insensitive to suboptimal effort in comparison to other commonly used neuropsychological measures. The current study examined performance differences on the entire WAIS-IV and WRAT-4 Reading, as well as the CVLT-II and several WMS-IV subtests, in 207 Veterans classified into Credible Effort ( n = 146) and Non-credible Effort ( n = 61) groups. Analyses revealed that the Non-credible Effort group performed significantly lower on all examined measures including verbal tests, with moderate to large effect sizes observed for most tests. Current findings thus indicate that WAIS-IV verbal subtests and reading ability measures, such as on the WRAT-4, are not insensitive to effects of non-credible effort. Consequently it is recommended that these tests not generally be used to estimate baseline intellectual functioning when found in the presence of non-credible effort. While there was broad performance suppression across all measures examined, results also showed a distinct continuum of test susceptibility with some measures being more or less sensitive to inadequate effort. Recommendations for future performance validity test development are presented. 相似文献

It is well documented that teachers feel unprepared to handle classroom management challenges in their classrooms. This lack of preparedness in classroom management, specifically for students with mental health concerns, is one of the leading reasons for teacher attrition. Yet, little is known about what teachers know about classroom management strategies and children’s mental health difficulties upon entering the classroom. The present study seeks to understand preservice teachers’ knowledge of classroom management strategies and attention-deficit/hyperactivity disorder (ADHD) in the United States. Participants were preservice teachers ( n = 107; 95.3% female; 75.4% Hispanic) about to enter their student teaching internship. Teachers’ accurate knowledge of classroom management strategies, accurate knowledge of ADHD, misperceptions of ADHD, and lack of knowledge of ADHD were investigated and related to teacher characteristics (i.e., hours of professional development) and sense of efficacy. Teacher knowledge of classroom management stategies, attention-deficit/hyperactivity disorder (ADHD), and sense of efficacy were evaluated using self-report measures. Overall, preservice teachers achieved 60.7% accuracy on the measure of classroom management strategies and 49% accuracy on the knowledge of ADHD measure. There were no associations between teachers’ knowledge of ADHD or classroom management strategies and teacher efficacy or characteristics. The results of this study reveal large gaps in preservice teachers’ knowledge of ADHD and classroom management strategies. Implications for teacher training programs are discussed. 相似文献

Clinical theory predicts that individuals high in psychopathic traits possess average or above average intelligence; however findings in adult and child samples have been mixed. The present study aimed to investigate (1) the relationship between verbal and nonverbal intelligence and the three dimensions of psychopathy (callous-unemotional (CU) traits, narcissism, impulsivity); and (2) whether these dimensions moderate the association between verbal and nonverbal intelligence and the severity of antisocial behavior. Participants were 361 adolescents aged 9–18 years (68% boys) and their parents, drawn from four samples with different levels of risk for antisocial behavior. Families were disadvantaged and 25% were from an ethnic minority. Verbal intelligence was unrelated to parent-reported CU traits, narcissism or impulsivity after controlling for gender, sociodemographic disadvantage, sample, antisocial behavior and hyperactivity. Narcissism, but not CU traits or impulsivity, was significantly related to lower nonverbal IQ. None of the three psychopathic trait dimensions moderated the relationship between verbal or nonverbal IQ and antisocial behavior. CU traits, narcissism, hyperactivity and inclusion in the very high or high risk samples were significantly related to more severe antisocial behavior. Results contradict the widely held view that psychopathic traits are associated with better than average verbal or nonverbal intelligence. 相似文献

Neuropsychiatric symptoms are common in Parkinson’s disease (PD) and add significantly to the burden of disease. These symptoms are most commonly part of the disease spectrum owing to pathological changes within relevant brain regions. Neuropsychiatric problems include disorders of cognition, ranging from mild cognitive impairment to dementia, psychotic symptoms, including, most commonly, well-formed visual hallucinations and paranoid delusions, and mood disorders, such as depression and anxiety. The other common cause of neuropsychiatric problem is secondary to use of dopaminergic drugs. Some PD patients may develop behavioral disorders, including impulse control disorders (ICDs) and addictive symptoms. Psychosis can be due to a mixture of underlying pathology, with triggering or worsening of symptoms with changes to PD medications. Currently, management of these disorders primarily uses therapies developed for general psychiatry and cognitive neurology, rather than specifically for PD. However, significant adverse effects, such as worsening of the motor symptoms of PD, can limit use of some drug therapies. Identification of drug-induced symptoms, such as ICDs, enables withdrawal of the offending drug as the principal management strategy. Research is ongoing in an effort to develop more specific therapies for PD-related neuropsychiatric symptoms. 相似文献

The current study used a high cognitive load cross-examination procedure to determine whether this would improve undergraduate students’ ability to detect deception in children aged 9 to 12 years. The participants ( n = 88) were asked to determine whether children's accounts of an event included a true denial, false denial, true assertion or false assertion about a game played during a home visit occurring one week prior. Overall, the high cognitive load cross-examination did not improve detection rates, in that participants were at chance level for both direct examination (49.4%) and cross-examination (52.3%). Accuracy for true stories was greater than for false stories. Cross-examination improved the detection rates of the false stories, but worsened the accuracy for the true stories. The participants did however rate younger children's true reports to be more credible and believable than their false reports. Participants rated older children's false reports as more credible and believable than their true reports. 相似文献

Cognitive impairment in drug-dependent patients receiving methadone maintenance treatment has been reported previously, although the literature is limited and results remain controversial. Long-term effects under stable methadone maintenance treatment (MMT) and the possibility of improvement in cognitive performance during long-term substitution treatment have rarely been investigated. We performed a comparative study investigating differences in cognitive functions under short- and long-term methadone treatment to test the hypothesis that patients perform better under long- than under short-term MMT. Seventy-seven patients were assessed cross-sectional either at least 30 days after the start of MMT (short-term group, n=35) or after at least 6 months of MMT (long-term group, n=42) with a comprehensive neuropsychological test battery on intelligence, learning and memory, attention and executive functions. Urine screenings were performed immediately before neuropsychological testing to check for concomitant drug use. Our findings may suggest, with all due caution, a slightly better performance of the long-term group in executive functions and visuo-construction. No group differences were found in attentional functions and learning and memory. More longitudinal research and studies controlling for the effects of dosage and duration of opioid addiction are necessary to examine whether cognitive ability may improve under long-term MMT. 相似文献
