The Relation Between Self-Report Mindfulness and Performance on Tasks of Sustained Attention

Validation of self-report mindfulness measures has been promising, although comparisons with non-self-report instruments are lacking. Because past research suggests that mindfulness training is associated with improved attention, this study predicted that higher self-report mindfulness would be positively related to performance on tasks of sustained attention. Fifty undergraduates completed the Mindful Attention Awareness Scale (MAAS), the Kentucky Inventory of Mindfulness Skills (KIMS), the Cognitive and Affective Mindfulness Scale, Revised (CAMS-R), and performed the Continuous Performance Test II (CPT-II) and the Paced Auditory Serial Addition Test (PASAT). Mindfulness scores, as measured by the MAAS and CAMS-R, were negatively related to target omissions on the CPT-II (ps ≤ 0.001), but were not related to PASAT performance (ps ≥ 0.11). Scores on the KIMS were not related to the CPT-II or PASAT (ps ≥ 0.15). Results suggest that self-report mindfulness is related to exaggerated lapses of attention, as measured by the CPT-II.     

Two Factors to be Considered in the Design of Experiments in Anxiety and Motor Behavior

The authors examined the influence that attentional focus on either a postural or a suprapostural task had on the performance of each task. Participants (N = 32) stood on an inflated rubber disk and held a pole horizontally. All participants performed under 4 attentional focus conditions: external (disk) or internal (feet) focus on the postural task, and external (pole) or internal (hands) focus on the suprapostural task. Compared with internal focuses, external focuses on either task resulted in similar and reduced postural sway. Response frequency on each task increased when participants focused on the respective task. Finally, an external focus on either task produced higher frequencies of responding on the suprapostural task. The authors conclude that suprapostural task goals have a stronger influence on postural control than vice versa, reflecting the propensity of the motor system to optimize control processes on the basis of the desired movement effect.     

不同注意形式调节听感觉门控的神经机制

前脉冲抑制(prepulse inhibition, PPI)是听感觉门控的测量模型, 反映了听觉系统的早期信息选择功能。尽管PPI的主要神经环路位于脑干, 研究发现PPI可以被注意自上而下调节。然而, 已有研究并未区分不同注意(特征注意和空间注意)对PPI的特异性调节, 并且神经机制方面的研究集中于听皮层区域, 仍缺乏对皮层下机制的探讨。在以往研究的成果基础之上, 借助听觉信息加工的双通路模型, 采用行为测量、脑电和脑成像技术, 揭示特征和空间两种注意调节PPI的神经活动在听觉系统中的层次性神经表达。包括1)建立特征注意和空间注意调节PPI的统一行为模型, 考察两种注意调节PPI的时间动态性异同; 2)两种注意调节PPI的脑干分离机制, 即前脉冲刺激包络和精细结构成分加工在注意调节PPI中的作用差异; 3)两种注意调节PPI的关键脑区和脑网络差异。     

Modality-repetition and attentional effects on reflex blinking in infants and adults

The ability of a brief prepulse to inhibit reflexively elicited startle is a robust phenomenon in adults of several species but is weak or absent in infants. The possibility that afferent processing of the prepulse is inadequate in infants was tested by assessing the integrity of two other types of reflex modulation that occur in modality-specific paths, that is, attenuation by repetition of same-modality stimuli and enhancement by modality-selective attention. The reflex, measured by electromyographic activity of the muscle controlling blink, was elicited by intense light flashes or noise bursts preceded by brief acoustic or visual prepulses and delivered during attention-directing acoustic or visual foregrounds that evoked cardiac deceleration. Modality-repetition effects were evidenced by smaller peak blink magnitude and longer latency of blinking to same than to different modality pairs and did not differ as a function of age (4-month-old infants or college students). Attention effects were also seen in both infants and adults and, in accord with previous findings, were evident in magnitude for infants and latency for adults. Thus, immaturity in paths mediating these effects could not explain delayed development of prepulse inhibition. Other possibilities include delayed maturation of extrinsic inhibition or of transient-processing systems.     

Differences Between ADHD Inattentive and Combined Types on the CPT

Two samples of school-age boys with attention-deficit/hyperactivity disorder (ADHD-Combined and ADHD-Inattentive Types) and a non-ADHD control group were administered an AX version of the continuous performance task (CPT) to examine specific sustained attention deficits. Three levels of time-on-task were included to study performance declines, and 3 interstimulus intervals were included to examine vigilance deficits. As predicted by R. A. Barkley's and H. C. Quay's behavior inhibition deficit models (R. A. Barkley, 1997; H. C. Quay, 1997), the performance of the ADHD-Combined Type (ADHD-C) participants deteriorated more quickly than the other samples. No significant evidence of vigilance deficits among the inattentive (ADHD-IA) sample was found. These findings suggest that distinct criteria for the two ADHD subtypes may be warranted when the CPT is used for diagnostic assessment, and sustained attention-related declines in performance may be typical of the ADHD-C Type only.     

Attachment,Behavioral Inhibition,and Anxiety in Preschool Children

This study examined the association between insecure attachment, behavioral inhibition, and anxiety in an at risk sample of preschool children. The relationship between maternal anxiety and child anxiety was also assessed. Participants were 104 children aged 3–4 years who were assessed for behavioral inhibition and mother–child attachment (using the Strange Situation procedure). DSM-IV criteria were used to assess childhood anxiety disorders. Insecure attachment and behavioral inhibition were both independently associated with child anxiety, even after controlling for the effect of maternal anxiety. Maternal anxiety was also associated with child anxiety. This study identified both constitutional and environmental factors associated with the expression of anxiety in young children. Furthermore, the highest levels of anxiety were shown by children who were behaviorally inhibited and insecurely attached and whose mothers were also anxious.     

Search asymmetry, sustained attention, and response inhibition

In the present experiment, we used search asymmetry to test whether the sustained attention to response task is a better measure of response inhibition or sustained attention. Participants performed feature present and feature absent target detection tasks using either a sustained attention to response task (SART; high Go low No-Go) or a traditionally formatted task (TFT; high No-Go low Go) response format. In addition to performance, we employed functional near infrared spectroscopy (fNIRS) to measure lateral cerebral oxygenation levels and self-reports of Tense Arousal, Energetic Arousal, task related and unrelated thoughts occurring during the tasks. Detections were lower and reaction times longer in the feature absent search than the feature present search regardless of response format. Detections were lower, but reaction times shorter in the SART than the TFT regardless of feature search. Greater right than left frontal hemisphere activation occurred in the SART than the TFT. In addition, the SART was more fatiguing based on self-reports than the TFT, but there were no differences in Task-Unrelated Thoughts across task conditions. Overall, the results suggest the SART places high response inhibition, not necessarily sustained attention, demands on participants.     

Anxiety sensitivity, conscious awareness and selective attentional biases in children

The current study investigated whether physical anxiety sensitivity (AS) is associated with selective attentional biases to affective stimuli in children. The dot-probe paradigm was used to examine the deployment of attention towards words pertaining to anxiety symptomatology, socially threatening words, and positive words, in samples of 8-10-year-old children. Word pairs were presented under both masked and unmasked conditions. Irrespective of masking, children high in physical AS displayed an attentional vigilance for emotional words relative to neutral words, whereas those low in physical AS displayed a relative avoidance of such material. The results of this study are interesting as they not only suggest the presence of automatic AS-related biases in childhood, but that this is a general emotionality bias rather than one related to specific anxiety-related stimuli.     

Examining the Relationship Between Mathematics Anxiety and Mathematics Performance: An Instructional Hierarchy Perspective

This study investigated the relationship between mathematics anxiety, fluency, and error rates in basic mathematical operations among college students. College students were assigned to one of two groups (high anxiety or low anxiety) based on results from the Fennema-Sherman Mathematics Anxiety Scale (FSMAS). Both groups were then presented with timed tests in basic mathematical operations (addition, subtraction, multiplication, division, and linear equations). Results suggested that the higher mathematics anxiety group had significantly lower fluency levels across all mathematical operations tests. However, there were no significant differences in error rates between the two groups across any of the probes suggesting that mathematics anxiety is more related to higher levels of learning than to the initial acquisition stage of learning. Discussion focuses on a) stages of learning and their potential relationship to mathematics anxiety, b) the relationship between mathematics anxiety and mathematics performance, and c) directions for future research.     

The Relation Between Emotional Dysregulation and Anxiety and Depressive Symptoms, Pain-Related Anxiety, and HIV-Symptom Distress Among Adults with HIV/AIDS

The current study investigated the relations between emotional dysregulation and anxiety and depressive symptoms, pain-related anxiety, and HIV-symptom distress among individuals living with HIV/AIDS. This research is important in its explanatory value regarding the unique effects of emotional dysregulation as it relates to psychological and disease-specific distress given high rates of distress specific to HIV infection (e.g. medicatin side-effects, stigma). Participants included 164 adults (17.1 % female, Mage = 48.40, SD?=?9.57) with HIV/AIDS. Results indicated that emotional dysregulation was significantly and positively related to anxiety and depressive symptoms, pain-related anxiety, and HIV-symptom distress. All emotional dyregulation effects were evidenced above and beyond the variance accounted for by demographic and HIV-specific characteristics, and the main effects of anxiety sensitivity and distress intolerance. Findings are discussed in terms of the importance of emotional dysregulation in negative affective experiences within the HIV/AIDS population.     

Interstimulus Intervals and Sensory Modality Modulate the Impact of a Cognitive Task on Postural Control

The present literature not only reveals the use of a wide variety of cognitive tasks but variability in their interaction with postural control. The question then arises, as to, whether postural control is sensitive to specific features of a cognitive task. The present experiment assessed the impact of cognitive tasks with interstimulus intervals (ISI) of varied duration and sensory modality on postural control in young adults. Seventeen participants (23.71 ± 1.99 years old) were instructed to stand on a force platform while concurrently performing cognitive tasks with ISIs of two and 5 s. The tasks were presented both, auditorily and visually. The visual tasks consisted of counting the total occurrence of a single digit. The auditory tasks consisted of counting the total occurrence of a single letter. Performing the cognitive tasks with an ISI of 2 s resulted only in an increase in the anteroposterior mean power frequency. Presenting the tasks visually also significantly reduced area of 95% confidence ellipse and AP and mediolateral sway variability. These results may suggest that ISIs can modify postural performance by altering the allocation of attentional focus. Also, presenting tasks using a visual sensory modality appears to yield lower postural sway.     

Attachment, Behavioral Inhibition, and Anxiety Disorders Symptoms in Normal Adolescents

The current study examined relationships between attachment style, behavioral inhibition, and anxiety disorders symptoms not only relying on youths' self-report but also including the parents' point of view. A large group of young adolescents aged 11–15 years and their parents (N = 280) completed measures of attachment style and behavioral inhibition and the Revised Children's Anxiety and Depression Scale, a questionnaire designed to measure symptoms of anxiety disorders in terms of the Diagnostic and Statistical Manual of Mental Disorders. Highly similar results were found for child and parent report. That is, attachment style and behavioral inhibition were found to be interrelated with insecure attachment being associated with higher levels of behavioral inhibition. Furthermore, adolescents who were classified as insecurely attached and/or high on behavioral inhibition displayed higher levels of anxiety disorders symptoms. Finally, attachment status and behavioral inhibition both accounted for a unique proportion of the variance of anxiety disorders symptomatology.

The shared and unique genetic relationship between mental well-being,depression and anxiety symptoms and cognitive function in healthy twins

Alterations to cognitive function are often reported with depression and anxiety symptoms, yet few studies have examined the same associations with mental well-being. This study examined the association between mental well-being, depression and anxiety symptoms and cognitive function in 1502 healthy adult monozygotic (MZ) and dizygotic (DZ) twins, and the shared/unique contribution of genetic (G) and environmental (E) variance. Using linear mixed models, mental well-being was positively associated (p?β?=?0.127), inhibition (β?=?0.096), cognitive flexibility (β?=?0.149), motor coordination (β?=?0.114) and working memory (β?=?0.156), whereas depression and anxiety symptoms were associated (p?β?=??0.134), inhibition (β?=??0.139), cognitive flexibility (β?=??0.116) and executive function (β?=??0.139). Bivariate twin modelling showed well-being shared a small environmental correlation with motor coordination and a small genetic correlation with working memory. Trivariate twin modelling showed well-being shared a small genetic correlation with inhibition, whereas depression and anxiety symptoms shared a small environmental correlation with inhibition. The remaining variance was mostly driven by unique G and/or E variance. Overall, well-being and depression and anxiety symptoms show both independent and shared relationships with cognitive functions but this is largely attributable to unique G or E variance and small shared G/E variance between pairs of variables.     

Associations Between Anxiety and Marital Adjustment

Cognitive-behavioral theories of marital functioning and contextual models of close relationships highlight the importance of proximal affect states such as anxiety in couple functioning. Despite these assertions, research examining the role of state anxiety is lacking in the literature on intimate relationships. In this study, the authors examined state anxiety and marital adjustment in a sample of 45 couples. Hierarchical regression analyses indicated that husbands' Time 1 anxiety can predict their own and their wives' subsequent reports of marital adjustment. Wives' Time 1 anxiety did not predict their own or their husbands' subsequent reports of marital adjustment. In this study, the authors focused on the role of husband anxiety in marital adjustment and on implications for further study of the contextual model of close relationships.     

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.     

The Relation Between Cognitive Development and Anxiety Phenomena in Children

We examined the relation between cognitive development and fear, anxiety, and behavioral inhibition in a non-clinical sample of 226 Dutch children aged 4–9 years. To assess cognitive development, children were tested with Piagetian conservation tasks and a Theory-of-Mind (TOM) test. Fears were measured by means of a self-report scale completed by the children, while anxiety symptoms and behavioral inhibition were indexed by rating scales that were filled out by parents. Significant age trends were observed for some anxiety phenomena. For example, younger children displayed higher fear scores, whereas older children exhibited higher levels of generalized anxiety. Most importantly, results of regression analyses (in which we controlled for age) indicated that cognitive development, and in particular TOM ability, made a unique and significant contribution to various domains of behavioral inhibition. In all cases, higher levels of TOM were associated with lower levels of behavioral inhibition. In general, percentages of explained variance were rather small (i.e., <6%), indicating that the role of cognitive development in various anxiety phenomena is limited.     

The Structure of Self-Consciousness in Children and Young Adolescents and Relations to Social Anxiety

Decades of research have examined the structure of self-consciousness in adults and its relationship to social anxiety. This study examined the structure of self-consciousness via the Self-Consciousness Scales (Fenigstein et al., J. Consult. Clin. Psychol. 43:522–527, 1975) in a school sample of 175 children and young adolescents (92 girls; mean age = 11.5). Confirmatory factor analysis best supported a five-factor solution (Internal State Awareness, Self-Reflectiveness, Appearance Consciousness, Style Consciousness and Social Anxiety). Although some factor based subscales evidenced low internal consistencies, convergent and discriminant correlations with self-report measures of social phobia, negative affect, and positive affect as well as parent-report measures of internalizing and externalizing problems provided additional support for the five-factor model. Future studies should further examine the multidimensional nature as well as the developmental course of self-consciousness and its relation to social anxiety longitudinally.

Selective Attention and Anxiety: A Perspective on Developmental Issues and the Causal Status

A plethora of studies on selective information processing in anxiety have been carried out over the past two decades. One of the most robust findings is that anxiety is associated with selective attention (SA) for threatening information. The rationale of research into SA is that it is assumed to play a vital role in the maintenance, and even in the etiology of anxiety disorders. It is the aim of this paper to explicate on the validity of this assumption. There is ample evidence that anxiety enhances SA. Although there is a lack of studies on the effect of SA on anxiety, there is now some evidence that SA increases the level of anxiety. This leads us to conclude that SA is not a by-product of anxiety only. Hence, the suggestion that SA plays a role in the maintenance of anxiety disorders seems to be justified. Studies on SA in children suggest that if SA plays any role at all in the development of anxiety disorders, it is not the SA in itself that is a vulnerability factor, but the continuation of this SA. Individuals who develop an anxiety disorder could have difficulty learning to inhibit this SA. Considering the finding that SA increases the level of anxiety, the authors suggest that anxiety in childhood causes failure to inhibit SA, which in turn enhances the vulnerability to anxiety disorder in adulthood.
