The effects of trait and state anxiety on attention to emotional images: An eye-tracking study

Attentional biases for threatening stimuli have been implicated in the development of anxiety disorders. However, little is known about the relative influences of trait and state anxiety on attentional biases. This study examined the effects of trait and state anxiety on attention to emotional images. Low, mid, and high trait anxious participants completed two trial blocks of an eye-tracking task. Participants viewed image pairs consisting of one emotional (threatening or positive) and one neutral image while their eye movements were recorded. Between trial blocks, participants underwent an anxiety induction. Primary analyses examined the effects of trait and state anxiety on the proportion of viewing time on emotional versus neutral images. State anxiety was associated with increased attention to threatening images for participants, regardless of trait anxiety. Furthermore, when in a state of anxiety, relative to a baseline condition, durations of initial gaze and average fixation were longer on threat versus neutral images. These findings were specific to the threatening images; no anxiety-related differences in attention were found with the positive images. The implications of these results for future research, models of anxiety-related information processing, and clinical interventions for anxiety are discussed.     

Individual differences in anxiety and executive functioning: A multidimensional view

The relationship between individual differences in anxiety and executive functioning was investigated in a sample of young adults. Verbal and spatial working memory, resistance to interference, negative priming, and task‐switching measures were used to assess three executive functioning dimensions: updating, inhibition, and shifting. An additional index of basic psychomotor speed was added to this cognitive battery. According to the multidimensional interaction model of anxiety proposed by Endler (1997), state (cognitive–worry and autonomic–emotional) and trait (related to social evaluation, physical danger, ambiguous situations, and daily routines) anxiety were assessed in this evaluation context. Results indicated that shifting and inhibition (negative priming) efficiency were negatively related to state (cognitive–worry) and trait (related to social evaluation) anxiety. However, there was a relative advantage of subjects higher in social evaluation apprehensions in their memory updating performance. The results are consistent with several predictions of the attentional control theory (Eysenck, Derakshan, Santos, & Calvo, 2007), and are relevant for research regarding the interaction of situational, personality, and cognitive functioning dimensions.     

Trait anxiety and impaired control of reflective attention in working memory

The present study investigated whether the control of reflective attention in working memory (WM) is impaired in high trait anxiety individuals. We focused on the consequences of refreshing—a simple reflective process of thinking briefly about a just-activated representation in mind—on the subsequent processing of verbal stimuli. Participants performed a selective refreshing task, in which they initially refreshed or read one word from a three-word set, and then refreshed a non-selected item from the initial phrase or read aloud a new word. High trait anxiety individuals exhibited greater latencies when refreshing a word after experiencing the refreshing of a word from the same list of semantic associates. The same pattern was observed for reading a new word after prior refreshing. These findings suggest that high trait anxiety individuals have difficulty resolving interference from active distractors when directing reflective attention towards contents in WM or processing a visually presented word.     

Trait anxiety, trait depression, worry, and memory

A study is reported which investigated the proposal that high trait anxiety is associated with a memory bias for worry themes. Forty-five participants were categorised as being high or low trait anxious on the basis of scores on the (Spielberger et al., 1983) (Manual for the State-Trait Anxiety Inventory (Form Y) (1983)). The participants were requested to rate a number of worry and non-worry statements for how much they generally thought about the issues represented by them. Analysis of the ratings given by the participants showed that low trait anxiety individuals thought about the non-worry items significantly more than worry items. The high trait anxiety participants, however, showed little or no difference in the amount of time spent thinking about worry and non-worry themes. In a subsequent free recall task of the statements it was observed that the low trait anxiety group recalled significantly more non-worry than worry items, whereas there was no such difference for the high trait group. It was also found that the degree of memory bias was related to both positive affectivity and trait anxiety. The implications of such findings are discussed.     

Trait impulsiveness and executive function in healthy young adults

Performance-based neuropsychological tests are often used to assess planning and impulse control, but the extent to which these measures reflect trait impulsiveness or specific dimensions of trait impulsiveness is not clear. This study used the Barratt Impulsiveness Scale-11 (BIS-11; [Patton, J. H., Stanford, M. S., & Barratt, E. S. (1995). Factor structure of the Barratt Impulsiveness Scale. Journal of Clinical Psychology, 51, 768–774.]) to examine the relationship between various dimensions of trait impulsiveness and performance on several executive function tests in healthy young adults. Total BIS-11 scores correlated with performance on measures of planning and impulse control. Higher non-planning impulsiveness scores, which indicate poorer self-control and lower cognitive complexity, correlated most strongly with performance on a maze test that measures planning and impulse control (r = .58). These results provide support for the convergent validity of pencil-and-paper maze-based measures of planning and impulse control.     

Multidimensionality of state and trait anxiety: A cross-cultural study comparing american,canadian, israeli and german young adults

Abstract

The psychometric adequacy of the Endler Multidimensional Anxiety Scales (EMAS) was examined in samples of American, Canadian, Israeli, and West German male and female young adults. Also investigated was the generalizability of the interactional model of anxiety to a diverse set of cultural contexts. This interactional model distinguishes between multidimensional dimensions of state and trait anxiety. The EMAS was developed to both reliably and independently assess multidimensional state and trait anxiety. Three hundred and seventy-four American undergraduates, 292 Canadian undergraduates, 326 Israeli undergraduates, and 304 West German undergraduates completed the EMAS in a non-stressful situation. The EMAS subscales were found to be highly reliable scales in all four cultural groups. Consistent empirical support was found across cultural groups for both the distinction between state and trait anxiety and the multidimensionality of these two constructs. Significant gender and cultural differences were found across the various EMAS subscales. Women were more likely than men to report being anxious in social evaluation and physical danger situations. In comparison to the other 3 groups, the Israelis reported being less anxious in social evaluation and physical danger situations. Results are discussed in terms of cultural differences between Canada, the United States, West Germany and Israel.     

Mindfulness meditation practice and executive functioning: Breaking down the benefit

This paper focuses on evidence for mindfulness meditation-related benefits to executive functioning, processes important for much of human volitional behaviour. Miyake et al. (2000) have shown that executive functions can be fractionated into three distinct domains including inhibition, working memory updating, and mental set shifting. Considering these separable domains, it is important to determine whether the effects of mindfulness can generalize to all three sub-functions or are specific to certain domains. To address this, the current review applied Miyake et al.’s (2000) fractionated model of executive functioning to the mindfulness literature. Empirical studies assessing the benefits of mindfulness to measures tapping the inhibition, updating, and shifting components of executive functioning were examined. Results suggest a relatively specific as opposed to general benefit resulting from mindfulness, with consistent inhibitory improvement, but more variable advantages to the updating and shifting domains. Recommendations surrounding application of mindfulness practice and future research are discussed.     

Assessment of executive functioning in childhood epilepsy: The Tower of London and BRIEF

Children and adolescents with epilepsy are known to demonstrate executive function dysfunction, including working memory deficits and planning deficits. Accordingly, assessing specific executive function skills is important when evaluating these individuals. The present investigation examined the utility of two measures of executive functions—the Tower of London and the Behavioral Rating Inventory of Executive Functioning (BRIEF)—in a pediatric epilepsy sample. Ninety clinically referred children and adolescents with seizures were included. Both the Tower of London and BRIEF identified executive dysfunction in these individuals, but only the Tower of London variables showed significant relations with epilepsy severity variables such as age of epilepsy onset, seizure frequency, number of antiepileptic medications, etc. Further, the Tower of London and BRIEF variables were uncorrelated. Results indicate that objective measures of executive function deficits are more closely related to epilepsy severity but may not predict observable deficits, as reported by parents. Comprehensive evaluation of such deficits, therefore, should include both objective measures as well as subjective ratings from caregivers.     

Trait worry is associated with difficulties in working memory updating

The current study investigated the effects of trait worry, a subcomponent of trait anxiety, on the process of updating information in working memory (WM). A leading theory on anxiety and executive functions, attentional control theory (ACT), states that anxiety is not related to WM updating in emotionally neutral situations. Previous research, however, has focused almost exclusively on WM span tasks that primarily emphasised storage, rather than the updating of WM representations. Moreover, few studies have directly examined the effects of trait worry. In this study, 116 subjects performed a WM updating task that required the memorisation of short lists of words and the within-trial removal of some of these items from WM. Results indicated that levels of trait worry were not related to word-span performance, but were related to performance on trials that required subjects to effectively update WM. Moreover, these effects were observed only for trait worry, not for levels of anxious arousal or comorbid levels of dysphoria. These results support the hypothesis that trait worry is related to WM updating performance and thereby extend ACT in new directions.     

Individual differences in executive functioning and theory of mind: An investigation of inhibitory control and planning ability

This research examined the relative contributions of two aspects of executive function-inhibitory control and planning ability-to theory of mind in 49 3- and 4-year-olds. Children were given two standard theory of mind measures (Appearance-Reality and False Belief), three inhibitory control tasks (Bear/Dragon, Whisper, and Gift Delay), three planning tasks (Tower of Hanoi, Truck Loading, and Kitten Delivery), and a receptive vocabulary test (Peabody Picture Vocabulary Test [PPVT-3]). Multiple regression analyses indicated that two inhibition tasks (Bear/Dragon and Whisper) were significantly related to theory of mind after accounting for age, receptive vocabulary, and planning. In contrast, the planning tasks did not share unique variance with theory of mind. These results increase our understanding of the specific nature of executive function-theory of mind relations during early childhood.     

The relations between children's communicative perspective-taking and executive functioning

Two experiments investigated children’s communicative perspective-taking ability. In Experiment 1, 4- to 5-year-old children were tested on two referential communication tasks, as well as on measures of inhibitory control, working memory, and cognitive flexibility. Results document children’s emergent use of the perspective of their speaking partner to guide their communicative behaviors in both a production and comprehension task. In Experiment 2, 3- to 4-year-old children used a speaker’s perspective to guide their interpretation of instructions. In both experiments, egocentric interpretations of speaker requests were negatively correlated with children’s inhibitory control skills. Results of these studies demonstrate that young children can differentiate between information that is accessible to the speaker versus privileged knowledge, and use this information to guide their communicative behaviors. Furthermore, the results suggest that children’s inhibitory control skills allow them to inhibit their own perspective, enabling them to make use of their communicative partner’s perspective.     

Opposite effects of anxiety and depressive symptoms on executive function: The case of selecting among competing options

People constantly face the need to choose one option from among many, such as when selecting words to express a thought. Selecting between many options can be difficult for anyone, and can feel overwhelming for individuals with elevated anxiety. The current study demonstrates that anxiety is associated with impaired selection across three different verbal tasks, and tests the specificity of this finding to anxiety. Anxiety and depression frequently co-occur; thus, it might be assumed that they would demonstrate similar associations with selection, although they also have distinct profiles of symptoms, neuroanatomy and neurochemistry. Here, we report for the first time that anxiety and depressive symptoms counter-intuitively have opposite effects on selection among competing options. Specifically, whereas anxiety symptoms are associated with impairments in verbal selection, depressive symptoms are associated with better selection performance. Implications for understanding the mechanisms of anxiety, depression and selection are discussed.     

Development of executive functioning in school-age Tunisian children

Research regarding executive functioning (EF) in children rarely focuses on populations in African or Middle-Eastern Arabic-speaking countries. The current study used a cross-sectional design to examine the developmental trajectories of school-age Tunisian children in three domains of executive control (inhibition of prepotent responses, cognitive flexibility, and working memory) as well as their mutual interactions and the effects of gender and parents’ education level. Inhibitory processes, cognitive flexibility, and working memory were assessed using the Stroop test, a version of the Hayling test adapted for children, simple and alternating tasks of verbal fluency, and verbal and visuospatial span tasks (forward and backward spans). The study population included 120 7- to 12-year-old Tunisian children (60 girls, 60 boys) who were grouped and matched for age, gender, and parents’ education level. The results revealed an overall effect of age on executive performance, whereas gender and parents’ education level showed non-significant effects. In addition, executive indices were significantly associated with fluid intelligence level. Partial correlation analyses (controlled for age) found significant links between indices that assessed the same executive process, except for inhibitory processes; the temporal indices for inhibitory processes showed relative independence. The correlations between indices that assessed distinct executive processes were weaker (but significant). Overall, the results suggest that executive components in school-age Tunisian children operate according to relatively homogeneous developmental trajectories, marked by peaks of maturity that differ according to the assessed index. A transcultural approach to EF is discussed in terms of the unity and diversity of its components.     

Objective measures of executive functioning are highly discrepant with parent-report in fetal alcohol spectrum disorders

The purpose of the current study was to evaluate the relationship between parent-report and objective measures of executive function in children diagnosed with Fetal Alcohol Spectrum Disorder (FASD). The participants were a clinical sample of 551 children who completed 597 evaluations, including initial and re-evaluations. Participants were 6–16 years old, with a mean age of 10. Pearson correlations were used to determine the relationship between performance-based measures and parent-report measures of executive functioning. Relationships among the same types of measures, that is, performance based or parent report, were also evaluated. The data largely demonstrate low nonsignificant correlations between performance-based measures and parental report of executive function. Parent-report measures were internally consistent as were objective measures. It is possible that a third variable, for example, parental frustration, significantly influences parent reports. It is also likely that objective measures, which are administered in a controlled environment, do not fully capture children’s day-to-day functioning. That is, a child may have the executive function abilities (i.e., good performance on objective measures) but may be unable to deploy the appropriate skills in their daily lives, as evidenced by parental report. Children with FASD who have executive function abilities but not implementation skills likely require different interventions than children who lack abilities and skills.     

Aging of the planning process: the role of executive functioning

This study tested whether the aging of executive functioning is linked to the decline in planning performance. Participants were divided into three groups: group 1 composed of 15 adults with a mean age of 22.7 years, group 2 composed of 15 adults with a mean age of 68.1 years and group 3 composed of 16 adults with a mean age of 78.75 years. Each participant took tests for shifting, inhibition, updating and processing speed. Planning was evaluated by the Tower of Hanoi task with 3 and 4 disks. Analyses of variance showed a main age effect on the many executive functioning and planning measures assessed. Analyses of regression indicated that combined processing speed and shifting accounted for 58.33% of performance on the 3-disk version, while processing speed accounted for only 36.86% of performance on the 4-disk version. These results are discussed in relation to two levels of the planning process: formulation and execution.     

From a state to a trait: Trajectories of state mindfulness in meditation during intervention predict changes in trait mindfulness

Theory suggests that heightening state mindfulness in meditation practice over time increases trait mindfulness, which benefits psychological health. We prospectively examined individual trajectories of state mindfulness in meditation during a mindfulness-based intervention in relation to changes in trait mindfulness and psychological distress. Each week during the eight-week intervention, participants reported their state mindfulness in meditation after a brief mindfulness meditation. Participants also completed pre- and post-intervention measures of trait mindfulness and psychological symptoms. Tests of combined latent growth and path models suggested that individuals varied significantly in their rates of change in state mindfulness in meditation during the intervention, and that these individual trajectories predicted pre-post intervention changes in trait mindfulness and distress. These findings support that increasing state mindfulness over repeated meditation sessions may contribute to a more mindful and less distressed disposition. However, individuals’ trajectories of change may vary and warrant further investigation.     

Association of television violence exposure with executive functioning and white matter volume in young adult males

Prior research has indicated that self-reported violent media exposure is associated with poorer performance on some neuropsychological tests in adolescents. This study aimed to examine the relationship of executive functioning to violent television viewing in healthy young adult males and examine how brain structure is associated with media exposure measures. Sixty-five healthy adult males (ages 18–29) with minimal video game experience estimated their television viewing habits over the past year and, during the subsequent week, recorded television viewing time and characteristics in a daily media diary. Participants then completed a battery of neuropsychological laboratory tests quantifying executive functions and underwent a magnetic resonance imaging (MRI) scan. Aggregate measures of executive functioning were not associated with measures of overall television viewing (any content type) during the past week or year. However, the amount of television viewing of violent content only, as indicated by both past-year and daily diary measures, was associated with poorer scores on an aggregate score of inhibition, interference control and attention, with no relationship to a composite working memory score. In addition, violent television exposure, as measured with daily media diaries, was associated with reduced frontoparietal white matter volume. Future longitudinal work is necessary to resolve whether individuals with poor executive function and slower white matter growth are more drawn to violent programming, or if extensive media violence exposure modifies cognitive control mechanisms mediated primarily via prefrontal cortex. Impaired inhibitory mechanisms may be related to reported increases in aggression with higher media violence exposure.     

The interaction between baseline trait anxiety and trauma exposure as predictor of post-trauma symptoms of anxiety and insomnia

In this study a prospective design was used to investigate the interaction between baseline trait anxiety and exposure to traumatic situations on post-trauma symptoms of anxiety and insomnia in a sample of Swedish peacekeeping soldiers serving in Kosovo. The result showed that pre-trauma trait anxiety interacted with exposure to traumatic situations predicting a higher post-trauma distress. Further, baseline trait anxiety and baseline symptoms of anxiety and insomnia predicted post-trauma symptoms of anxiety and insomnia. The results support a diathesis stress model in which high trait anxiety interacts with trauma exposure in the elicitation of anxiety-related distress but the study needs to be replicated before further conclusions can be drawn.     

Attention and executive functioning in infancy: Links to childhood executive function and reading achievement

This study provides the first analyses connecting individual differences in infant attention to reading achievement through the development of executive functioning (EF) in infancy and early childhood. Five‐month‐old infants observed a video, and peak look duration and shift rate were video coded and assessed. At 10 months, as well as 3, 4, and 6 years, children completed age‐appropriate EF tasks (A‐not‐B task, hand game, forward digit span, backwards digit span, and number Stroop). Children also completed a standardized reading assessment and a measure of verbal intelligence (IQ) at age 6. Path analyses on 157 participants showed that infant attention had a direct statistical predictive effect on EF at 10 months, with EF showing a continuous pattern of development from 10 months to 6 years. EF and verbal IQ at 6 years had a direct effect on reading achievement. Furthermore, EF at all time points mediated the relation between 5‐month attention and reading achievement. These findings may inform reading interventions by suggesting earlier intervention time points and specific cognitive processes (i.e. 5‐month attention).     

Linkages between childhood executive functioning and adolescent social functioning and psychopathology in girls with ADHD

We followed an ethnically and socioeconomically diverse sample of preadolescent girls with ADHD (n = 140) and matched comparison girls (n = 88) over a period of 5 years, from middle childhood through early/midadolescence, with the aim of determining whether childhood levels of executive function (EF) would predict adolescent multi-informant outcomes of social functioning and psychopathology, including comorbidity between externalizing and internalizing symptomatology. Predictors were well-established measures of planning, response inhibition, and working memory, along with a control measure of fine motor control. Independent of ADHD versus comparison group status, (a) childhood planning and response inhibition predicted adolescent social functioning and (b) childhood planning predicted comorbid internalizing/externalizing disorders in adolescence. Subgroup status (ADHD-Combined, ADHD-Inattentive, and comparison) moderated the relationship between childhood planning and adolescent internalizing/externalizing comorbidity, with the combined type revealing particularly strong associations between baseline planning and adolescent comorbidity. Mediation analyses indicated that adolescent social functioning mediated the prediction from childhood EF to comorbidity at follow-up; in turn, in the girls with ADHD, adolescent comorbidity mediated the prediction from childhood EF to social functioning at follow-up. We conclude that childhood interventions should target EF impairments in addition to behavioral symptoms.
