The current study examined the relation between infant sustained attention and infant EEG oscillations. Fifty‐nine infants were tested at 6 (= 15), 8 (= 17), 10 (= 14), and 12 (= 13) months. Three attention phases, stimulus orienting, sustained attention, and attention termination, were defined based on infants' heart rate changes. Frequency analysis using simultaneously recorded EEG focused on infant theta (2–6 Hz), alpha (6–9 Hz), and beta (9–14 Hz) rhythms. Cortical source analysis of EEG oscillations was conducted with realistic infant MRI models. Theta synchronization was found over fontal pole, temporal, and parietal electrodes during infant sustained attention for 10 and 12 months. Alpha desynchronization was found over frontal, central and parietal electrodes during sustained attention. This alpha effect started to emerge at 10 months and became well established by 12 months. No difference was found for the beta rhythm between different attention phases. The theta synchronization effect was localized to the orbital frontal, temporal pole, and ventral temporal areas. The alpha desynchronization effect was localized to the brain regions composing the default mode network including the posterior cingulate cortex and precuneus, medial prefrontal cortex, and inferior parietal gyrus. The alpha desynchronization effect was also localized to the pre‐ and post‐central gyri. The present study demonstrates a connection between infant sustained attention and EEG oscillatory activities.  相似文献

The purpose of this study was to compare the psychometric properties of the Screen for Cognitive Impairment in Psychiatry (SCIP) when applied to patients diagnosed with schizophrenia (n = 126) or bipolar I disorder (n = 76), and also to compare the cognitive impairment in both samples of patients and a control group (n = 83) using the SCIP and a complete neuropsychological battery. The SCIP is a scale intended to quickly and easily assess cognitive impairment in patients with severe psychiatric disorders. The results showed firstly that, in terms of internal consistency, temporal stability, dimensional structure, and criterion-referenced validity, the SCIP provides reliable and valid scores at an equivalent level in both schizophrenia and bipolar I disorder samples. Secondly, it showed that differential cognitive impairment between the two patient groups occurs only in verbal memory, although the effect size of the difference is small. Finally, compared with the control group, cognitive impairment was present at all levels in both groups of patients using both the SCIP and the neuropsychological battery, which indicates that the SCIP is a good screening tool for cognitive deficits in schizophrenia and bipolar and useful in clinical practice for healthcare professionals.  相似文献

Research suggests that people's aversion towards pattern deviancy—distortions of repeated forms or models—contributes to social phenomena, such as prejudice. Yet, the factors motivating pattern deviancy aversion remain unclear. Potentially, anxious attachment, as it entails hypervigilant detection of and reactivity to social inconsistency and unreliability, heightens pattern deviancy aversion. In Studies 1 (= 137) and 2 (= 102), anxious but not avoidant attachment predicted aversion towards broken patterns of geometric shapes. In Studies 3 (= 310) and 4 (= 470), experimentally inducing anxious versus avoidant and secure attachment (Study 3), and versus a neutral prime (Study 4), heightened pattern deviancy aversion. Controlling for participants’ aversion towards unbroken patterns, novel objects, and negative stimuli did not change these results. Our findings demonstrate that anxious attachment is one antecedent of pattern deviancy aversion, and suggest that pattern deviancy aversion may underlie links between anxious attachment and certain social phenomena.  相似文献

Self-esteem affects individuals in a variety of psychological processes substantially and extensively. While an increase in self-esteem over time was observed in the USA, different patterns of temporal change in self-esteem were observed in other societies. We analysed the responses (n = 305 229) collected between 1993 and 2016 from 609 articles to examine the patterns of temporal change in self-esteem in China and its relations with socioecological conditions. Additionally, we explored the patterns in different groups, including secondary school students (158 samples; n = 97 751), college students (427 samples; n = 153 474), and community participants (232 samples; n = 54 004). Some major findings were noted: (i) overall, the level of self-esteem increased over time. However, we also found a significant curvilinear trend in self-esteem with a decline followed by a recent increase; (ii) some evidence for the relationship between socioecological factors and self-esteem was obtained; and (iii) the patterns varied in different cohort groups. Specifically, secondary school students showed a different pattern, in which their self-esteem level did not show a significant linear trend and was not correlated with the examined socioecological factors. The implications on the theories for the relationship between personality characteristics and socioecological conditions were discussed.  相似文献

Cortical grey matter atrophy patterns have been reported in healthy ageing and Alzheimer disease (AD), but less consistently in the parietal regions of the brain. We investigated cortical grey matter volume patterns in parietal areas. The grey matter of the somatosensory cortex, superior and inferior parietal lobule was measured in 75 older adults (38 cognitively stable and 37 individuals with cognitive decline after 3 years). Dementia screening 6 years after scanning resulted in nine AD cases from the cognitively stable (n=3) and cognitive decline group (n=6), who were assigned to a third group, the preclinical AD group. When regional differences in cortical volume in the parietal lobe areas were compared between groups, significant differences were found between either the cognitive decline or stable group on the one hand and preclinical AD individuals on the other hand in the inferior parietal lobule. Group membership was best predicted by the grey matter volume of the inferior parietal lobule, compared to the other parietal lobe areas. The parietal lobe was characterised by a differential atrophy pattern based on cognitive status, which is in agreement with the 'last-developed-first-atrophied' principle. Future studies should investigate the surplus value of the inferior parietal lobe as a potential marker for the diagnosis of AD compared to other brain regions, such as the medial temporal lobe and the prefrontal lobe.  相似文献

Patterns of cognitive ageing   总被引:6,自引:0,他引:6  
Neuroanatomical evidence suggests that normal ageing affects some brain areas, and the “local” functions they support, earlier and more severely than others. Changes appear to be especially marked in the hippocampus, temporal association and prefrontal cortex. Evidence from classical neuropsychological studies suggests that these brain areas are associated with memory and “executive” functions, respectively. We may, therefore, expect that tests purported to measure these functions may be disproportionately affected in old age and that there may be evidence for some separation of these functions even within neurologically normal populations. What we also know, however, is that measures reflecting general fluid ability also decline with increasing age, so any hypothesis relating to specific “local” deficits must acknowledge and account for any “globar” changes in performance. Volunteers (n=162) aged between 60–80 years who had completed the Cattell and Cattell Culture Fair Intelligence Test (CCF) completed the Cambridge Automated Neuropsychological Test Battery (CANTAB). The CANTAB has been administered to several patient populations and tests from the battery have been shown to be sensitive to damage in both temporal and prefrontal areas (Owen et al., 1996). Results from the test battery showed that both the Paired Associate Learning and Spatial Recognition tests were the most sensitive to normal ageing even when CCF is accounted for. In contrast, this performance on the “executive” tests, shown to be sensitive to frontal lobe damage, was not related to age, and CCF scores predicted performance on these tests. These results are discussed in relation to theories of cognitive ageing and patterns of change and in relation to several important methodological and theoretical considerations for the study of executive function.

We explored differences in distress scores at intake as well as the change in anxiety and depression scores over the course of 12 therapy sessions for Native Hawaiian and Pacific Islander (NHPI) college students. Data were collected from the Center for Collegiate Mental Health (= 256,242). Results support the notion that NHPI college students experience anxiety and depression in therapy differently from other ethnic groups with moderate-to-large magnitudes of effect.  相似文献

We demonstrate how religiosity predicts relationships between personal values and perceptions of morality in four studies across two cultures (Jews in Israel and mainly Christians in the US). In Studies 1A (= 337) and 1B (= 200), we explored the commonalities and differences between religious and non-religious participants in the association between values and the importance of being moral. In Studies 2A (= 131) and 2B (= 250), we tested the role of religiosity in the association between values and evaluations of others’ morality. Power (negatively) and Benevolence (positively) were associated with morality across levels of religiosity. The associations with Conservation were more positive for more religious participants; the associations with Universalism were more positive for less religious participants. Finally, the associations with at least one of the Openness-to-change values were more negative if a person was more religious. Studies 2A and 2B showed these associations existed over and above differences in personal values.  相似文献

Via four studies (= 901), we developed an improved Belief in Superstition Scale (BSS) composed of three distinct components (belief in bad luck, belief in good luck, and the belief that luck can be changed), whose structure was supported through exploratory (Study 1) and confirmatory (Studies 2 and 3) factor analyses using divergent samples. We found that among theoretical predictors, higher ‘chance’ locus of control (i.e., the belief that chance/fate controls one's life) best predicted all three BSS subscales (Studies 2–3). In Study 3, we found that BSS subscale scores were reliable, but largely invariant across age and education with a non‐general psychology sample. In Study 4, the BSS subscales best predicted participants’ superstitious attitudes and behaviour in a new lottery drawing paradigm among other commonly used superstition scales. Taken together, our results indicate that the BSS is a valuable addition to the burgeoning research on superstitious attitudes and behaviour.  相似文献

Racial, ethnic, religious, and sexual minority populations are growing rapidly in the West. We investigate predictors and consequences of threat responses to perceived minority group size, and perceptions of minority group size itself. Study 1 (= 274) finds that right-wing adherence predicts greater size threat, whereas lower numerical ability predicts larger perceived group size (confirmed in Studies 2–3). Study 2 (Sample 1, = 124; Sample 2, = 263) finds that the relation between right-wing adherence and prejudice toward minorities exhibits an indirect effect via group size threat (but not perceived size), explaining 35–66% of this relation. Study 3 (= 310) finds a comparable indirect effect explaining 27–40% of this relation, even after statistically controlling for indirect effects of realistic, symbolic, and terroristic threat. These findings provide novel insights into psychological processes surrounding perceived minority group size, identifying size threat as especially crucial in understanding intergroup relations.  相似文献

We examine the sensitivity to change in the Evaluation of Social Systems (EVOS) scale, which assesses relationship quality and collective efficacy. In Study 1 we conducted a waitlist‐control, short‐term couple therapy RCT study (= 43 couples) with five systemic therapy sessions treating communication and partnership problems; our intent was to provide high external validity. Construct validity of EVOS was assessed by comparison with additionally applied scales (Family Scales; Outcome Questionnaire, OQ‐45.2). In Study 2, = 332 individuals completed an experiment with high internal validity in order to verify sensitivity to change in three different social contexts. Results from Study 1 revealed a significant increase in relationship quality in the treatment group directly after treatment, as compared to the control group. Sensitivity to change was slightly better for EVOS than for other measures. While this positive change could not be fully sustained between posttreatment and a 4‐week follow‐up, EVOS score did not fall below baseline and pretreatment levels, supporting moderate‐to‐large sensitivity to change. Study 2 supported high sensitivity to change in EVOS for couple relations, family relations, and work‐team relationships. Therefore, EVOS can be used as an outcome measure to monitor the process of systemic interventions focusing on relationship quality and collective efficacy. Due to its sensitivity to change, EVOS can provide evidence for treatment success with regard to relationship aspects.  相似文献

The 3-factor structure of the Normative Multiculturalism Scale (NMS)—Contact with Diversity (CD), Multicultural Ideology (MI), and Multicultural Policies and Practices (MPP)—was tested and confirmed with community samples from New Zealand (= 381) and the United States (= 311). Correlations with criterion measures (e.g., perceived minority disadvantage and attitudes to diversity) supported the criterion validity of the subscales. NMS factors were then examined as predictors of social connectedness in a British community sample (= 347). Hierarchical multiple regression revealed that MI predicted general trust, and MI and MPP predicted national attachment. While MPP was associated with greater perceived threat, this relationship was dampened by the joint influences of MI and CD. The research presents a novel perspective on multiculturalism by adopting a normative approach and examining the main and interaction effects of contact with diversity, multicultural ideology, and multicultural policies on interpersonal and intergroup outcomes.  相似文献

Recent evidence demonstrated that neuropsychological assessment may be considered a valid marker of neurodegeneration in idiopathic REM sleep behaviour disorder (iRBD). However, little is known about the possible neuropsychological heterogeneity within the iRBD population. This retrospective study aimed to identify and describe different neuropsychological phenotypes in iRBD patients by means of a data-driven approach using latent class analysis. A total of 289 iRBD patients underwent a neuropsychological assessment evaluating cognitive domains: global cognition, language, short- and long-term memory, executive functions and visuospatial abilities. The presence of mild cognitive impairment (MCI) was also assessed. Latent class analysis was carried out to identify iRBD subtypes according to neuropsychological scores. The most parsimonious model identified three latent classes. Groups were labelled as follows: Class 2 “severely impaired” (n = 83/289): mean pathological scores in different tests, a high percentage of MCI multiple-domain and impairment in all neuropsychological domains. Class 1 “moderately impaired” (n = 44/289): mean neuropsychological score within the normal value, a high percentage of MCI (high risk to phenoconversion) and great impairment in the visuospatial domain. Class 3 “slightly impaired” (n = 162/289): no deficit worthy of attention except for short- and long-term memory. Our results suggest three different clinical phenotypes within the iRBD population. These findings may be relevant in the future for predicting the clinical trajectories of phenoconversion in iRBD.  相似文献

We tested antecedents (paternalistic beliefs; Study 1) and consequences (social change potential; Study 2) of autonomy- and dependency-oriented help and developed scales assessing paternalistic beliefs and both forms of help. In Study 1 (= 143 Germans), we focused on paternalistic beliefs as an antagonist to social change and a key distinguishing variable between engagement in both forms of help. As expected, paternalistic beliefs were positively related to dependency-oriented help, mediated by concern for a positive national moral image, but negatively related to autonomy-oriented help, mediated by perceived competence of refugees. In Study 2, both refugees (= 80) and Germans (= 94) perceived autonomy-oriented help to have more potential for social change than dependency-oriented help.  相似文献

Individuals with autism spectrum disorders (ASD) have difficulty understanding other minds (Theory of Mind; ToM), with atypical processing evident at both behavioural and neural levels. Individuals with conduct problems and high levels of callous‐unemotional (CU) traits (CP/HCU) exhibit reduced responsiveness to others' emotions and difficulties interacting with others, but nonetheless perform normally in experimental tests of ToM. The present study aimed to examine the neural underpinnings of ToM in children (aged 10–16) with ASD (= 16), CP/HCU (= 16) and typically developing (TD) controls (= 16) using a non‐verbal cartoon vignette task. Whilst individuals with ASD were predicted to show reduced fMRI responses across regions involved in ToM processing, CP/HCU individuals were predicted to show no differences compared with TD controls. The analyses indicated that neural responses did not differ between TD and CP/HCU groups during ToM. TD and CP/HCU children exhibited significantly greater medial prefrontal cortex responses during ToM than did the ASD group. Within the ASD group, responses in medial prefrontal cortex and right temporoparietal junction (TPJ) correlated with symptom severity as measured by the Autism Diagnostic Observation Schedule (ADOS). Findings suggest that although both ASD and CP/HCU are characterized by social difficulties, only children with ASD display atypical neural processing associated with ToM.  相似文献

In France, laïcité is a legal principle enforcing State secularism. However, research indicates that Modern (vs. traditional) beliefs about laïcité (ML) help legitimate prejudice against minorities. From Social Identity Theory, we hypothesized that ML should be positively linked with national identification, stereotyping, prejudice and support for discrimination. Accordingly, we demonstrate that ML independently predicts support for discriminatory policies (Study 1a, = 241) and Maghrebi IAT scores (Study 1b, = 242). ML mediates the link between national identification and Generalized Prejudice (Study 2a, = 215; Study 2d, = 114) as well as Support for Discriminatory Policies (Study 2b, = 250). Experimental corroboration of this mediation was provided (Study 2c, N = 100). An exploratory study showed that priming ML led to more support for discrimination through national identification (Study 3, = 89). These results reveal the important intergroup regulation feature of ML beliefs in France.  相似文献

Beyond money and possessions, how are the rich different from the general population? Drawing on a unique sample of high‐net‐worth individuals from Germany (≥1 million Euro in financial assets; = 130), nationally representative data (= 22,981), and an additional online panel (= 690), we provide the first direct investigation of the stereotypically perceived and self‐reported personality profiles of high‐net‐worth individuals. Investigating the broad personality traits of the Big Five and the more specific traits of narcissism and locus of control, we find that stereotypes about wealthy people's personality are accurate albeit somewhat exaggerated and that wealthy people can be characterized as stable, flexible, and agentic individuals who are focused more on themselves than on others.  相似文献

Some older adults cannot meaningfully participate in the testing portion of a neuropsychological evaluation due to significant cognitive impairments. There are limited empirical data on this topic. Thus, the current study sought to provide an operational definition for a futile testing profile and examine cognitive severity status and cognitive screening scores as predictors of testing futility at both baseline and first follow-up evaluations. We analysed data from 9,263 older adults from the National Alzheimer’s Coordinating Center Uniform Data Set. Futile testing profiles occurred rarely at baseline (7.40%). There was a strong relationship between cognitive severity status and the prevalence of futile testing profiles, χ2(4) = 3559.77, p < .001. Over 90% of individuals with severe dementia were unable to participate meaningfully in testing. Severity range on the Montreal Cognitive Assessment (MoCA) also demonstrated a strong relationship with testing futility, χ2(3) = 3962.35, p < .001. The rate of futile testing profiles was similar at follow-up (7.90%). There was a strong association between baseline dementia severity and likelihood of demonstrating a futile testing profile at follow-up, χ2(4) = 1513.40, p < .001. Over 90% of individuals with severe dementia, who were initially able to participate meaningfully testing, no longer could at follow-up. Similarly, there was a strong relationship between baseline MoCA score band and likelihood of demonstrating a futile testing profile at follow-up, χ2(3) = 1627.37, p < .001. Results can help to guide decisions about optimizing use of limited neuropsychological assessment resources.  相似文献

This study is the first to document suicidality among chronically homeless people with alcohol problems (= 134) and examine its trajectory following exposure to immediate, permanent, low‐barrier housing (i.e., Housing First). Suicidal ideation, intent, plans, and prior attempts were assessed at baseline and during a 2‐year follow‐up. Baseline suicidal ideation was over four times higher than in the general population. Two‐year, within‐subjects, longitudinal analyses indicated severity of suicidal ideation decreased by 43% from baseline to follow‐up. Significant decreases were also found for intent and clinical significance of ideation. No participants died by suicide during the 2‐year follow‐up.  相似文献

The dual-process model of recognition memory proposed by Jacoby (1991; see also Mandler, 1980) postulates the existence of two independent components of recognition memory: a conscious retrieval process (recollection) and an automatic component ( familiarity). Older adults appear to be impaired in recollection, but findings with respect to familiarity have been mixed. Studies of the brain bases of these components, using neurological patients, have also been inconclusive. We examined recollection and familiarity, using the process dissociation procedure, in older adults characterized on the basis of both their frontal and their medial temporal lobe function. Findings suggest that only some older adults, depending on their neuropsychological status, are impaired in recollection and/or familiarity: Recollection seems to involve both frontal and medial temporal lobe function, whereas familiarity appears to be dependent only on function associated with the medial temporal lobes.  相似文献
