学步期焦虑影响5岁幼儿创造力：一般认知和掌握动机的链式中介作用

儿童早期焦虑是一种常见的心理卫生问题, 影响个体中央执行功能的发展, 而个体中央执行功能所表现的认知能力的发展通常反映出个体创造性问题解决的过程。本研究采用追踪研究设计, 探讨了学步期儿童焦虑对其学龄前期创造力的长时影响及其潜在作用机制。来自北京的96个家庭(男孩42名, 女孩54名)参与了本研究。在儿童1岁和2岁时, 母亲填写中国版《12~36月龄幼儿情绪社会性评估量表》和家庭基本信息调查表。在儿童2岁时, 采用贝利婴幼儿发展量表评估幼儿的一般认知能力; 在儿童3岁时, 母亲报告儿童掌握动机情况; 在儿童5岁时, 采用托兰斯活动与动作创造性思维测验评估儿童的创造力。研究结果表明：(1)儿童学步期焦虑(广泛性焦虑和分离焦虑)可以显著负向预测其5岁时的创造力; (2)一般认知能力和掌握动机在儿童学步期焦虑(广泛性焦虑和分离焦虑)和学前期创造力之间的链式中介作用成立; (3)儿童学步期广泛性焦虑还可以通过直接负向预测掌握动机, 从而对其5岁创造力的表现产生消极影响。     

Effet du niveau d’études sur les performances en mémoire épisodique chez des adultes âgés : rôle médiateur de la métamémoire

Educational level is a factor of cognitive reserve and older adults with a higher level of formal education have a better memory performance than those having a lower educational level (Angel et al., 2010; Van Der Elst, Van Boxtel, Van Breukelen, & Jolles, 2005). Memory functioning can also be modulated by the beliefs and knowledge of a person about his/her own memory, that is, by his/her metamemory (Hultsch, Hertzog, & Dixon, 1987). The objective of this study was to examine the role of metamemory as a potential mediator of the effect of educational level on memory performance. Eighty-three older adults (60–80 years) participated in the experiment, they have been divided into two subgroups according to their educational level (high: 14.36 years and low level: 9.85 years). Episodic memory was evaluated with a cued recall task and metamemory by the Metamemory in Adulthood questionnaire (MIA). As shown by previous studies, results indicated that educational level had a significant effect on memory and metamemory, higher educational level was associated to better memory and metamemory capacities. At the MIA questionnaire, older adults with a high educational level affirmed using more internal and external strategies for learning, having higher motivation and perceiving less memory change with aging than older adults with a lower educational level. They also showed that the metamemory dimensions associated to the memory performance differed according to the educational level. For participants with a lower educational level, memory performance was correlated to the participants’ perception about their memory capacity and their knowledge about memory tasks, while for participants with a higher educational level, memory performance was correlated to the dimensions linked to memory control (strategies and motivation). Finally, the group effect was mediated by metamemory, specifically by the use of internal strategies. These results suggest that a prolonged educative experience would be associated to a better capacity to implement adapted strategies, which led individuals to maintain an optimal memory performance.     

Attachment at school age and academic performance.

The association between attachment and school-related cognitive functioning was longitudinally examined for a French Canadian sample of 108 school-age children. The affective quality of mother-child interaction patterns, child cognitive engagement, and quality of child attachment to mother were evaluated during a laboratory visit that included a separation-reunion procedure occurring when the children were approximately 6 years of age. Children's mastery motivation and academic performance were assessed 2 years later (at age 8). Analyses indicated that secure children had higher scores than their insecure peers on communication, cognitive engagement, and mastery motivation. Controlling children were at greatest risk for school underachievement, with the poorest performance on all measures except mastery motivation. Avoidant and ambivalent children were lowest on mastery motivation. Results of mediational analyses support the salience of mother-child interactional processes and child cognitive engagement at school age in explaining relations between attachment and cognitive functioning in school.

Turning it Upside Down: Areas of Preserved Cognitive Function in Schizophrenia

Patients with schizophrenia demonstrate marked impairments on most clinical neuropsychological tests. These findings suggest that patients suffer from a generalized form of cognitive impairment, with little evidence of spared performance documented in several large meta-analytic reviews of the clinical literature. In contrast, we review evidence for relative sparing of aspects of attention, procedural memory, and emotional processing observed in studies that have employed experimental approaches adapted from the cognitive and affective neuroscience literature. These islands of preserved performance suggest that the cognitive deficits in schizophrenia are not as general as they appear to be when assayed with clinical neuropsychological methods. The apparent contradiction in findings across methods may offer important clues about the nature of cognitive impairment in schizophrenia. The documentation of preserved cognitive function in schizophrenia may serve to sharpen hypotheses about the biological mechanisms that are implicated in the illness.     

Memory of pain and affect associated with migraine and non-migraine headaches

The main aims of this study were to assess memory of pain and pain-related affect in headache sufferers and to compare the pain memories of individuals who suffer from migraines and those who experience non-migraine headaches. A total of 313 women participated in the study, 86 of whom had a diagnosis of migraine headache. The women rated their state anxiety about having a headache, the intensity and unpleasantness of headache pain, and their emotions while actually experiencing a headache. Either three or six months later, the participants were asked to recall their state anxiety, the intensity and unpleasantness of pain, and the emotions they had felt. Regardless of the length of recall delay or migraine diagnosis, participants accurately remembered both pain intensity and unpleasantness. Together, recalled anxiety, experienced pain and recalled positive affect were the most important predictors of memories for headache, accounting for 41% and 37% of the total variance in recalled pain intensity and unpleasantness, respectively. However, participants overestimated recalled positive and negative affect. The effect of recalled affect on memory of headache, together with the overestimation of recalled affect, suggests that although memory of headache is accurate, it is influenced by distorted memories of affect.     

Associations Among Selective Attention, Memory Bias, Cognitive Errors and Symptoms of Anxiety in Youth

The purpose of this study was to examine the linkages among selective attention, memory bias, cognitive errors, and anxiety problems by testing a model of the interrelations among these cognitive variables and childhood anxiety disorder symptoms. A community sample of 81 youth (38 females and 43 males) aged 9-17 years and their parents completed measures of the child's anxiety disorder symptoms. Youth completed assessments measuring selective attention, memory bias, and cognitive errors. Results indicated that selective attention, memory bias, and cognitive errors were each correlated with childhood anxiety problems and provide support for a cognitive model of anxiety which posits that these three biases are associated with childhood anxiety problems. Only limited support for significant interrelations among selective attention, memory bias, and cognitive errors was found. Finally, results point towards an effective strategy for moving the assessment of selective attention to younger and community samples of youth.     

BIS, BAS, and bias: The role of personality and cognitive bias in social anxiety

The goal of the present research was to test the hypothesis that cognitive biases for negative and threatening social information mediate the effects of behavioral inhibition system (BIS) and behavioral approach system (BAS) sensitivity on social anxiety. Participants completed self-report measures of BIS and BAS and then underwent a social-threat induction procedure in which they were told they would have to perform a speech. A battery of cognitive bias measures was then administered, followed by a battery of state anxiety measures. Audience members also rated participants’ anxiety during the speech. Structural equation modeling was used to test the hypothesized model. As predicted, the fully-mediated model showed the best fit to the data, and higher BIS and lower BAS were found to have significant indirect effects on social anxiety via cognitive bias.     

Event memory and suggestibility in abused and neglected children: trauma-related psychopathology and cognitive functioning

This study examined event memory and suggestibility in 3- to 16-year-olds involved in forensic investigations of child maltreatment. A total of 322 children were interviewed about a play activity with an unfamiliar adult. Comprehensive measures of individual differences in trauma-related psychopathology and cognitive functioning were administered. Sexually and/or physically abused children obtained higher dissociation scores than neglected children, and sexually abused children were more likely to obtain a diagnosis of posttraumatic stress disorder than physically abused children, neglected children, and children with no substantiated abuse histories. Overall, older children and children with better cognitive functioning produced more correct information and fewer memory errors. Abuse status per se did not significantly predict children’s memory or suggestibility whether considered alone or in interaction with age. However, among highly dissociative children, more trauma symptoms were associated with greater inaccuracy, whereas trauma symptoms were not associated with increased error for children who were lower in dissociative tendencies. Implications of the findings for understanding eyewitness memory in maltreated children are discussed.     

Relations between children’s metamemory and strategic performance: Time-varying covariates in early elementary school

Although much is known about the development of memory strategies and metamemory during childhood, evidence for linkages between these memory skills, either concurrently or over time, has been limited. Drawing from a longitudinal investigation of the development of memory, repeated assessments of children’s (N = 107) strategy use and declarative metamemory were made to examine the development of these skills and the relations between them over time. Latent curve models were used first to estimate the trajectories of children’s strategy use and metamemory and then to examine predictors of children’s performance in each of these domains. Children’s metamemory at the beginning of Grade 1 was linked to child- and home-level factors, whereas the development of both skills was related to maternal education level. Additional modeling of the longitudinal relations between strategic sorting and metacognitive knowledge indicated that metamemory at earlier time points was predictive of subsequent strategy use.     

Perspectives on Memory for Trauma and Cognitive Processes Associated with Dissociative Tendencies

Summary

Cognitive science approaches can inform research in traumatic stress studies by articulating separate scientific issues that may be relevant to understanding alterations in memory and awareness for trauma. This article will first address general issues about disrupted memory and “knowledge isolation” for trauma, as well as introduce specific aspects of “betrayal trauma theory” (Freyd 1994, 1996) that inform our understanding of memory impairment. According to betrayal trauma theory, a potent motivation for knowledge isolation (including amnesia, dissociation, and unawareness) in the face of trauma is to preserve apparently necessary human relationships in which betrayal occurs. Results from three recent laboratory investigations of cognitive processes associated with dissociative tendencies are summarized. These laboratory investigations suggest that the attentional capacities of high dissocators are impaired under conditions of selective attention, but not divided attention. Furthermore, in our laboratory tasks high dissocators have impaired memory for emotionally charged words associated with sexual assault and abuse (e.g., “incest”) but not neutral words, as compared with low dissociators. The findings suggest that high dissociators use divided attention and multi-tasking as a way to control the flow of information. Such a view is consistent with betrayal trauma theory. Though in its infancy, this research draws on cognitive science and observations of traumatic response and offers much promise.     

Identification of tone duration, line length, and letter position: an experimental approach to timing and working memory deficits in schizophrenia

Patients with schizophrenia display numerous cognitive deficits, including problems in working memory, time estimation, and absolute identification of stimuli. Research in these fields has traditionally been conducted independently. We examined these cognitive processes using tasks that are structurally similar and that yield rich error data. Relative to healthy control participants (n = 20), patients with schizophrenia (n = 20) were impaired on a duration identification task and a probed-recall memory task but not on a line-length identification task. These findings do not support the notion of a global impairment in absolute identification in schizophrenia. However, the authors suggest that some aspect of temporal information processing is indeed disturbed in schizophrenia.     

Episodic memory deficits slow down the dynamics of cognitive procedural learning in normal ageing

Cognitive procedural learning is characterised by three phases, each involving distinct processes. Considering the implication of episodic memory in the first cognitive stage, the impairment of this memory system might be responsible for a slowing down of the cognitive procedural learning dynamics in the course of ageing. Performances of massed cognitive procedural learning were evaluated in older and younger participants using the Tower of Toronto task. Nonverbal intelligence and psychomotor abilities were used to analyse procedural dynamics, while episodic memory and working memory were assessed to measure their respective contributions to learning strategies. This experiment showed that older participants did not spontaneously invoke episodic memory and presented a slowdown in the cognitive procedural learning associated with a late involvement of working memory. These findings suggest that the slowdown in the cognitive procedural learning may be linked with the implementation of different learning strategies less involving episodic memory in older participants.

Reflexively mindblind: Using theory of mind to interpret behavior requires effortful attention

People commonly interpret others’ behavior in terms of the actors’ underlying beliefs, knowledge, or other mental states, thereby using their “theory of mind.” Two experiments suggest that using one’s theory of mind is a relatively effortful process. In both experiments, people reflexively used their own knowledge and beliefs to follow a speaker’s instruction, but only effortfully used their theory of mind to take into account a speaker’s intention to interpret those instructions. In Experiment 1, people with lower working memory capacity were less effective than people with larger working memory capacity in applying their theory of mind to interpret behavior. In Experiment 2, an attention-demanding secondary task reduced people’s ability to apply their theory of mind. People appear to be reflexively mindblind, interpreting behavior in terms of the actor’s mental states only to the extent that they have the cognitive resources to do so.     

Children’s eyewitness memory: A comparison of two interviewing strategies as realized by forensic professionals

A critical issue for developmental psychology is how to obtain accurate and complete eyewitness memory reports from preschoolers without offering suggestions that might result in false allegations. We examined effects of two interviewing strategies (police/verbal interviews and clinician/prop-assisted interviews) on young children’s reports about a medical examination. A total of 58 4-year-olds participated in the study, which conformed to a 2 (Interview Type) × 2 (Number of Interviews) factorial design. Analyses revealed that interviewers spent less time off topic and asked more free recall questions in the police/verbal interviews than in the clinician/prop-assisted interviews. Compared with police/verbal interviews, clinician/prop-assisted interviews resulted in significantly more correct rejections and commission errors in children’s memory reports. However, on a final free recall test, error rates were comparable across conditions. Higher child verbal intelligence predicted memory accuracy in police/verbal interviews, and greater parental attachment anxiety predicted children being asked a higher number of misleading questions. The study provides new insights into interview techniques that promote preschoolers’ accurate eyewitness reports.     

How young children judge whether a word is one they know: a dual criterion account

Word familiarity judgment may be important for word learning, yet little is known about how children make this judgment. We hypothesized that preschool-age children differ in the judgment criteria that they use and that this difference derives from individual differences in basic memory processes. Those who have superior phonological working memory, but who retrieve less semantic information than their peers, base the judgment on whether they recognize a word’s sound form. Those who show the opposite memory profile base the judgment on whether they retrieve a word’s meaning. The results of two studies of 3- and 4-year-olds were consistent with these claims. Among those performing poorly on one memory measure, judgment accuracy was directly related to performance on the other memory measure. These memory-judgment relations were also found to be highly specific. This is the first investigation to demonstrate the usefulness of an individual differences approach for identifying relations between linguistic judgment processes and basic memory processes during early childhood.     

Cognitive processes in psychological adaptation to miscarriage: A preliminary report

Abstract

Twenty-two women who wished to continue their pregnancies were interviewed several months after their first miscarriage. Levels of anxiety and depression showed an extremely high degree of variability. Cognitive processes in the form of a search for meaning, mastery and self-enhancement hypothesised to be important in adaptation to negative events were assessed. Having an explanation for the miscarriage and the experience leading to a general reappraisal of values were associated with lower levels of intrusive thoughts. A belief in a medical cause was linked to lower anxiety. Women believed that neither they themselves nor their doctors could exert much influence over the outcome of future pregnancies. Stronger belief in personal control was associated with higher anxiety levels. There is a need to consider not only the emotional consequences of miscarriage but also the cognitive mediators influencing such responses and although based upon a small sample this study initiates that process.     

Cognitive niches: an ecological model of strategy selection

How do people select among different strategies to accomplish a given task? Across disciplines, the strategy selection problem represents a major challenge. We propose a quantitative model that predicts how selection emerges through the interplay among strategies, cognitive capacities, and the environment. This interplay carves out for each strategy a cognitive niche, that is, a limited number of situations in which the strategy can be applied, simplifying strategy selection. To illustrate our proposal, we consider selection in the context of 2 theories: the simple heuristics framework and the ACT-R (adaptive control of thought-rational) architecture of cognition. From the heuristics framework, we adopt the thesis that people make decisions by selecting from a repertoire of simple decision strategies that exploit regularities in the environment and draw on cognitive capacities, such as memory and time perception. ACT-R provides a quantitative theory of how these capacities adapt to the environment. In 14 simulations and 10 experiments, we consider the choice between strategies that operate on the accessibility of memories and those that depend on elaborate knowledge about the world. Based on Internet statistics, our model quantitatively predicts people's familiarity with and knowledge of real-world objects, the distributional characteristics of the associated speed of memory retrieval, and the cognitive niches of classic decision strategies, including those of the fluency, recognition, integration, lexicographic, and sequential-sampling heuristics. In doing so, the model specifies when people will be able to apply different strategies and how accurate, fast, and effortless people's decisions will be.     

Valence of autobiographical memories: The role of mood, cognitive reappraisal, and suppression

The selective recall of positive memories is thought to be an effective mood repair technique, but little research has examined individual differences in the motivation or ability to implement this strategy. This study examined factors considered likely to impact valenced memory recall: dysphoria and emotion regulation strategies (i.e., cognitive reappraisal and suppression). Dysphoria was related to memory negativity but not positivity, whereas cognitive reappraisal was associated with positivity but not negativity. Suppression was not reliably related to the valence of self-reported memories, but was associated with increased accessibility of negative memories, as indicated by a response time measure. Our results indicate a relationship between cognitive reappraisal and more positive memory and suggest that the experience of dysphoria is more strongly related to negativity than positivity of memory. Our findings highlight the utility of examining emotion regulatory variables, in addition to mood, in the study of valenced memory recall, and underscore the importance of including both behavioral and self-report memory measures.
