Error detection is one of the functions of the executive attention network, a brain system involved in executive control that includes the anterior cingulate cortex and other prefrontal regions. Despite the key role of this function in a wide range of life outcomes, very limited research has examined the early development of the network and whether its functional efficacy is related to environmental factors. Electrophysiological studies with adults have shown oscillatory activity in theta (4–7 Hz) range arising from medial frontal cortex that follows the detection of self‐committed or observed errors. In the current study, we designed a novel experimental procedure that involved a familiarization phase with simple three‐pieces puzzles followed by an experimental phase in which toddlers observed the puzzles being formed either correctly or incorrectly. Observation of incorrect configurations produced increased potentials in midline channels and greater power theta activity for both toddlers (= 56) and adults (= 14). In addition, socioeconomic status of the family in general, and parental education in particular, contributed to individual differences in the amplitude of the error‐related signal and associated theta power in toddlers, indicating that children raised in lower SES families show poorer activation of the executive attention network. These data demonstrate the influence of environmental factors at the earliest stages of development of the executive attention network. Importantly, the results show that error‐detection EEG signals can be used as neural markers of the initial development of executive attention, which can be of great help for the early detection of risk for developmental disorders involving deficits in this function.  相似文献

Dichotic Listening (DL) is a valuable tool to study emotional brain lateralization. Regarding the perception of sadness and anger through affective prosody, the main finding has been a left ear advantage (LEA) for the sad but contradictory data for the anger prosody. Regarding an induced mood in the laboratory, its consequences upon DL were a diminished right ear advantage (REA) for the induction of sadness and an increased REA for the induction of anger. The global results fit with the approach-withdrawal motivational model of emotional processing, pointing to sadness as a right hemisphere emotion but anger processed bilaterally or even in the left hemisphere, depending on the subject's preferred mode of expression. On the other hand, the study of DL in clinically depressed patients found an abnormally larger REA in verbal DL tasks which was predictive of therapeutic pharmacological response. However, the mobilization of the available left hemisphere resources in these responders (reflected in a higher REA) would indicate a remission of the episode but would not assure the absence of new relapses.  相似文献

A system of care for abused and neglected infants and young children should adopt a comprehensive perspective, with mental health considerations systematically incorporated into policies and decisions affecting children and their families. Children age birth to 5 years have disproportionately high rates of maltreatment, with long-term consequences for their mental and physical health. Research on normal development and developmental psychopathology has shown that early development unfolds in an ecology of transactional influences among biological, interpersonal, and environmental domains. Psychologists should collaborate with other early intervention disciplines to create systems of care based on an ecological-transactional model of development that includes early mental health principles in order to serve the needs of these young children. Didactic courses, practicums, and internships in infant and early childhood mental health should become integral components of undergraduate and graduate curricula in psychology in order to build capacity to achieve this goal. Recommendations are offered for systemic change by integrating infant and early childhood mental health principles into existing systems of care for young children and their families.  相似文献

Stress has been identified as a main factor involved in the cognitive changes that occur during the aging process. This study investigated sex differences in the relationship between the magnitude of the acute stress-induced salivary cortisol response and memory performance among middle-aged people. To this end, 16 men and 16 women (aged 54-72 years) were exposed to the Trier Social Stress Test and a control condition in a crossover design. Afterwards their memory performance was measured using a standardized memory test (Rey's Auditory Verbal Learning Test). Only among women, there was an acute impact of stress on memory performance and a significant relationship between a higher cortisol response to the stressor and poorer memory performance in both the stress and control conditions. Additionally, a poorer memory performance was related to earlier timing of sexual maturation (age at menarche), which was also marginally related to higher cortisol reactivity to stress. These results confirm that sex is a critical factor in the relationship between cortisol and poor memory performance. Furthermore, the findings emphasize a strong link between the individual cortisol response to stress and memory functioning among postmenopausal women.  相似文献

Body dissatisfaction and associated attitudes were studied in 18–24?years old women from universities in Rosario, Santa Fe, Argentina (N?=?118), Jo?o Pessoa, Paraíba, Brazil (N?=?81), and mid-Atlantic U.S. (N?=?102). Based on anecdotal reports, theoretical concerns, and empirical studies, we expected greater body dissatisfaction and negative body attitudes in our Argentine and Brazilian samples than in the U.S. sample. Body dissatisfaction was a significant problem in all samples, but we found few differences in levels of body dissatisfaction. The Argentine and Brazilian samples scored lower than the U.S. sample on measures associated with disordered eating, experienced less pressure to be thin, and were less likely to internalize the thin body ideal. Body shame was highest in the Brazilian sample and lowest in the Argentine sample. Cultural features in Argentina and Brazil that may offer some level of protection against the thin body ideal were discussed.  相似文献

Burnout is typically viewed as resulting from situational factors (e.g., workload). However, as burnout is partly a reaction to frustrated goal striving, dispositional goal orientation may also be important. We used Hobfoll's ( 1989 ) conservation of resources model to develop hypotheses for relationships between goal orientation and 3 dimensions of burnout. Self‐report questionnaire measures of the 2 × 2 model of goal orientation (Elliot & McGregor, 2001 ) and burnout were administered to undergraduate students. Structural equation modeling revealed that all 4 dimensions of goal orientation were related to burnout. Avoidance‐related dimensions were positively associated and approach‐related dimensions were negatively associated with burnout. The findings suggest the importance of considering the role of motivational dispositions in development, prediction, and prevention of burnout.  相似文献

This article employs George Lakoff and Mark Johnson's work on metaphor (1980) to examine the current use of the term “learning outcomes” within higher education. It argues that “learning outcomes” is an ontological metaphor (education becomes focused on results that one can understand and measure) that resonates with contemporary academic capitalism. Yet because metaphors highlight some things and conceal others, thinking about teaching and disciplines using “learning outcomes” hides other dimensions of academic capitalism and obscures unquantifiable and highly complex aspects of education. Finally, the article explores ways in which an emphasis upon outcomes has consequences for the field of Religious Studies.  相似文献

Studies of contagious yawning have reported inconsistent findings regarding whether dogs exhibit this behavior and whether it is mediated by social-cognitive processes or the result of physiological arousal. We investigated why some dogs yawn in response to human yawns; particularly, whether these dogs are exceptional in their ability to understand human social cues or whether they were more physiologically aroused. Sixty shelter dogs were exposed to yawning and nonyawning control stimuli demonstrated by an unfamiliar human. We took salivary cortisol samples before and after testing to determine the role of arousal in yawn contagion. Dogs were tested on the object-choice task to assess their sensitivity for interpreting human social cues. We found that 12 dogs yawned only in response to human yawns (i.e., appeared to exhibit yawn contagion), though contagious yawning at the population level was not observed. Dogs that exhibited yawn contagion did not perform better on the object-choice task than other dogs, but their cortisol levels remained elevated after exposure to human yawning, whereas other dogs had reduced cortisol levels following yawning stimuli relative to their baseline levels. We interpret these findings as showing that human yawning, when presented in a stressful context, can further influence arousal in dogs, which then causes some to yawn. Although the precise social-cognitive mechanisms that underlie contagious yawning in dogs are still unclear, yawning between humans and dogs may involve some communicative function that is modulated by context and arousal.  相似文献

In recent years, new sequencing technologies known as next generation sequencing (NGS) have provided scientists the ability to rapidly sequence all known coding as well as non-coding sequences in the human genome. As the two emerging approaches, whole exome (WES) and whole genome (WGS) sequencing, have started to be integrated in the clinical arena, we sought to survey health care professionals who are likely to be involved in the implementation process now and/or in the future (e.g., genetic counselors, geneticists and nurse practitioners). Two hundred twenty-one genetic counselors— one third of whom currently offer WES/WGS—participated in an anonymous online survey. The aims of the survey were first, to identify barriers to the implementation of WES/WGS, as perceived by survey participants; second, to provide the first systematic report of current practices regarding the integration of WES/WGS in clinic and/or research across the US and Canada and to illuminate the roles and challenges of genetic counselors participating in this process; and third to evaluate the impact of WES/WGS on patient care. Our results showed that genetic counseling practices with respect to WES/WGS are consistent with the criteria set forth in the ACMG 2012 policy statement, which highlights indications for testing, reporting, and pre/post test considerations. Our respondents described challenges related to offering WES/WGS, which included billing issues, the duration and content of the consent process, result interpretation and disclosure of incidental findings and variants of unknown significance. In addition, respondents indicated that specialty area (i.e., prenatal and cancer), lack of clinical utility of WES/WGS and concerns about interpretation of test results were factors that prevented them from offering this technology to patients. Finally, study participants identified the aspects of their professional training which have been most beneficial in aiding with the integration of WES/WGS into the clinical setting (molecular/clinical genetics, counseling and bioethics) and suggested that counseling aids (to assist them when explaining aspects of these tests to patients) and webinars focused on WES/WGS (for genetic counselors and other health care professionals) would be useful educational tools. Future research should permit us to further enhance our knowledge of pitfalls and benefits associated with the introduction of these powerful technologies in patient care and to further explore the roles and opportunities for genetic counselors in this rapidly evolving field.  相似文献
