The malleability of age-related positive gaze preferences: training to change gaze and mood

Older adults show positive gaze preferences, but to what extent are these preferences malleable? Examining the plasticity of age-related gaze preferences may provide a window into their origins. We therefore designed an attentional training procedure to assess the degree to which we could shift gaze and gaze-related mood in both younger and older adults. Participants completed either a positive or negative dot-probe training. Before and after the attentional training, we obtained measures of fixations to negatively valenced images along with concurrent mood ratings. We found differential malleability of gaze and mood by age: for young adults, negative training resulted in fewer posttraining fixations to the most negative areas of the images, whereas positive training appeared more successful in changing older adults' fixation patterns. Young adults did not differ in their moods as a function of training, whereas older adults in the train negative group had the worst moods after training. Implications for the etiology of age-related positive gaze preferences are considered.     

What are you looking at? Infants’ neural processing of an adult's object‐directed eye gaze

Previous research suggests that by 4 months of age infants use the eye gaze of adults to guide their attention and facilitate processing of environmental information. Here we address the question of how infants process the relation between another person and an external object. We applied an ERP paradigm to investigate the neural processes underlying the perception of the direction of an adult's eye gaze in 4-month-old infants. Infants showed differential processing of an adult's eye gaze, which was directed at a simultaneously presented object compared to non-object-directed eye gaze. This distinction was evident in two ERP components: The Negative component, reflecting attentional processes, and the positive slow wave, which is involved in memory encoding. The implications of these findings for the development of joint attention and related social cognitive functions are discussed.     

The influence of motivational priority on younger and older adults’ positive gaze preferences

ABSTRACT

The present study investigated whether manipulating emotional goal priority within a series of divided attention tasks influenced the presence or absence of age-related positive gaze preferences. Across two experiments, participants viewed image pairs while performing an auditory version of a 3-back n-back task. In Experiment 1, four conditions were presented: full attention viewing, emotion regulation priority, n-back task priority, and equal priority. The same conditions were included for Experiment 2, with the addition of a “no priority” divided attention condition and full attention n-back condition. Both age groups demonstrated greater positive relative to negative preferences when emotion regulation goals were prioritized, in spite of the challenge presented by a secondary task in divided attention. The present findings are discussed in terms of how positive emotional processing preferences may emerge despite cognitive control constraints in old age. Implications for the role of explicit motivations for older adults’ positivity preferences are discussed.     

Does Looking at the Positive Mean Feeling Good? Age and Individual Differences Matter

In this paper, we link age differences in gaze patterns toward emotional stimuli to later mood outcomes. While one might think that looking at more positive emotional material leads to better moods, and looking at more negative material leads to worse moods, it turns out that links between emotional looking and mood depend on age as well as individual differences. Though older people can feel good by looking more at positive material, in some cases young adults actually feel better by engaging visually with the negative. These age effects are further moderated by attentional abilities. Such findings suggest that different age groups may use looking differently, and this may reflect their preferences for using distinct emotion regulatory strategies. This work also serves as a reminder that regulatory efforts are not always successful at improving mood.     

Cognitive emotion regulation in adulthood and old age: positive gaze preferences across two strategies

While positive emotional functioning may be enhanced across adulthood and old age, research is mixed as to the types of regulatory strategies that are more or less beneficial for facilitating well-being. The goal of the present study was to examine how specific cognitive emotion regulation strategies assumed to rely on varying levels of effortful processing (selective attention vs. reappraisal) would impact regulatory behaviors (via eye gaze deployment) and resultant affective outcomes. Participants viewed a series of positive, negative, and neutral film clips while their eyes were tracked across three conditions: passive viewing, selective attention, and reappraisal. Results revealed that (a) both younger and older adults displayed positive fixation preferences and showed mood improvement across both regulatory conditions and (b) there was a marginal association between positive fixation and post-regulation mood. Implications for linking positivity to emotion regulation and well-being across adulthood are discussed.     

Looking while unhappy: mood-congruent gaze in young adults, positive gaze in older adults

Recent findings that older adults gaze toward positively valenced stimuli and away from negatively valenced stimuli have been interpreted as part of their attempts to achieve the goal of feeling good. However, the idea that older adults use gaze to regulate mood, and that their gaze does not simply reflect mood, stands in contrast to evidence of mood-congruent processing in young adults. No previous study has directly linked age-related positive gaze preferences to mood regulation. In this eye-tracking study, older and younger adults in a range of moods viewed synthetic face pairs varying in valence. Younger adults demonstrated mood-congruent gaze, looking more at positive faces when in a good mood and at negative faces when in a bad mood. Older adults displayed mood-incongruent positive gaze, looking toward positive and away from negative faces when in a bad mood. This finding suggests that in older adults, gaze does not reflect mood, but rather is used to regulate it.     

Neurophysiological characteristics of acts of remembering in the process of positive ageing / Características neurofisiológicas de los actos de recuerdo en el proceso de envejecimiento positivo

Abstract

‘Acts of remembering’ refer to the conscious cognitive process that facilitates recognition of socioculturally relevant events. This study presents an analysis of the differences and similarities between the morphological characteristics and architecture of Event-Related Potentials associated with the visual recognition of cultural events, by comparing a group of older adults (n = 15) with a group of young adults (n = 17). The results show similar modulations in the N1, P2, P300 and N400 components while a differential modulation appears in N200, a component that has been associated with attentional processes. Two ways of interpreting the results are put forward: one suggests that with age come greater difficulties for cognitive processing and the other suggests that older adults have a particular interest in this type of material.     

Gaze behaviour during walking in young adults with developmental coordination disorder

BackgroundIndividuals with Developmental Coordination Disorder (DCD) experience difficulty with motor coordination and this affects their daily functioning. Research indicated inferior visuospatial processing and oculomotor control in DCD. As visual information is essential for locomotor control, more insight in the gaze behaviour of this population during walking is required and crucial for gaze training interventions as a possible means to improve daily functioning of children and adults with DCD.AimThis study explored differences and similarities in gaze behaviour during walking between typically developing young adults and those with DCD.Methods and proceduresTen young adults with DCD (age: 22.13 ± 0.64) and ten typically developing individuals (age: 22.00 ± 1.05) completed a walking task in which they had to place their feet on irregularly placed targets wearing eye tracking glasses.Outcomes and resultsIndividuals with DCD walked slower and demonstrated a different gaze strategy compared to their neurotypical peers as they fixated almost each and every target sequentially. Typically developing individuals, on the other hand, directed gaze further along the path and often fixated areas around the targets.Conclusions and implicationsDespite adequate walking performance in daily situations in young adults with DCD, fundamental control deficits persist into adulthood.What this paper adds?This paper is the first to demonstrate differences in gaze behaviour between young adults with DCD and typically developing individuals in a task that resembles a task of daily living, as previous research focused on laboratory tasks. This is a valuable finding as DCD has a clear impact on the daily life. Furthermore, this study demonstrated that the fundamental control deficits of DCD persist into adulthood despite frequent performance and practice of these daily tasks. Lastly, these findings might contribute to the therapeutic potential of gaze training interventions to improve the daily functioning of children and adults with DCD.     

Deliberate real-time mood regulation in adulthood: The importance of age,fixation and attentional functioning

While previous research has linked executive attention to emotion regulation, the current study investigated the role of attentional alerting (i.e., efficient use of external warning cues) on younger (N=39) and older (N=44) adults’ use of gaze to regulate their mood in real time. Participants viewed highly arousing unpleasant images while reporting their mood and were instructed to deliberately manage how they felt and to minimise the effect of those stimuli on their mood. Fixations toward the most negative areas of the images were recorded with eye tracking. We examined whether looking less at the most negative regions, compared to each individual's own tendency, was a beneficial mood regulatory strategy and how it interacted with age and alerting ability. High alerting older adults, who rely more on external cues to guide their attention, experienced a smaller decline in mood over time by activating a less-negative-looking approach (compared to their own average tendency), effectively looking away from the most negative areas of the images. More negative gaze patterns predicted better mood for younger adults, though this effect decreased over time. Alerting did not moderate gaze–mood links in younger adults. Successful mood regulation may thus depend on particular combinations of age, fixation, and attention.     

Aging and goal-directed emotional attention: distraction reverses emotional biases

Previous findings reveal that older adults favor positive over negative stimuli in both memory and attention (for a review, see Mather & Carstensen, 2005). This study used eye tracking to investigate the role of cognitive control in older adults' selective visual attention. Younger and older adults viewed emotional-neutral and emotional-emotional pairs of faces and pictures while their gaze patterns were recorded under full or divided attention conditions. Replicating previous eye-tracking findings, older adults allocated less of their visual attention to negative stimuli in negative-neutral stimulus pairings in the full attention condition than younger adults did. However, as predicted by a cognitive-control-based account of the positivity effect in older adults' information processing tendencies (Mather & Knight, 2005), older adults' tendency to avoid negative stimuli was reversed in the divided attention condition. Compared with younger adults, older adults' limited attentional resources were more likely to be drawn to negative stimuli when they were distracted. These findings indicate that emotional goals can have unintended consequences when cognitive control mechanisms are not fully available.     

Gaze direction affects walking speed when using a self-paced treadmill with a virtual reality environment

BackgroundIn a previous study it was observed that participants increase their walking speed during a dual task while walking on a self-paced treadmill in a virtual reality (VR) environment (Gait Real time Analysis Interactive Lab (GRAIL)). This observation is in contrast with the limited resources hypothesis, which suggests walking speed of healthy persons to decrease when performing a cognitive dual task.AimThe aim of the present study was therefore to determine whether the cognitive demand of the task, an aroused feeling, discrepancy in optic flow or a change in gaze direction caused participants to walk faster in this computer assisted rehabilitation environment.MaterialsThe GRAIL included a self-paced treadmill, a motion-capture system and synchronized VR environments.MethodsThirteen healthy young adults (mean age 21.6 ± 2.5) were included in this study. Participants walked on the self-paced treadmill while seven different intervention conditions (IC) were offered. Prior to each IC, a control condition (CC) was used to determine the natural self-selected walking speed. Walking speed during the last 30 s of each IC was compared with the walking speed during the last 30 s of the preceding CC.ResultsResults show that the height on which a visual task was presented in the VR environment, influenced walking speed. Participants walked faster when gaze was directed above the focus of expansion.SignificanceThese findings contribute to a further understanding of the differences between walking in a real life environment or computer assisted rehabilitation environment. When analyzing gait on a self-paced treadmill in the future, one must be attentive where to place a visual stimulus in the VR environment.     

“Cold” Cognitive Control and Attentional Symptoms in Anxiety: Perceptions Versus Performance

Clinically significant anxiety is associated with an array of attentional symptoms (e.g., difficulty concentrating; unwanted thought) that are subjectively experienced as severe. However, neuropsychological findings are mixed with respect to the presence of cognitive deficits that can account for these symptoms. Contextualizing predictions from established clinical theories (e.g., Attentional Control Theory) within contemporary, neurobiologically derived models of cognitive control (Dual Mechanisms of Control Theory), the present study investigated the relationship between “cold” proactive and reactive cognitive control, task effort, and subjective attentional symptoms (difficulty concentrating; unwanted thought) in a mixed clinical sample of individuals with generalized anxiety disorder (GAD) and/or obsessive-compulsive disorder (OCD) and a comparison sample of healthy controls. Clinical status moderated the relationship between attentional symptoms (attentional focusing and trait worry) and proactive cognitive control response time. Clinical status also moderated the relationship between trait worry and task effort. Higher trait worry was associated with slower proactive control and lower effort in healthy participants, but faster proactive control in clinical participants. Self-reported attentional focusing showed differential validity vis-à-vis proactive control response time in clinical versus healthy participants. Post-hoc conditional effects analysis suggested more accurate self-appraisals in healthy controls, but was not significant after correction for multiple comparisons. Preliminary evidence suggested that differences in task effort in anxious versus healthy adults may relate to subjective attentional symptoms in GAD and OCD.     

Age differences in managing response to sadness elicitors using attentional deployment,positive reappraisal and suppression

The current study investigated age differences in the use of attentional deployment, positive reappraisal and suppression while regulating responses to sadness-eliciting content. We also tested to what extent these emotion regulation strategies were useful for each age group in managing response to age-relevant sad information. Forty-two young participants (M_age = 18.5, SE = .15) and 48 older participants (M_age = 71.42, SE = 1.15) watched four sadness-eliciting videos (about death/illness, four to five minutes long) under four conditions—no-regulation (no regulation instructions), attentional deployment (divert attention away), positive reappraisal (focus on positive outcomes) and suppression (conceal emotional expressions). We assessed negative emotional experience, expression, skin conductance level (SCL) and visual fixation duration while participants watched the emotional clips and followed the instructions for each condition. Results suggest that older adults were more successful than younger adults at implementing both attentional deployment and positive reappraisal. Ability to suppress emotions appears to remain stable with age. Within age-group comparisons suggested that for the older adults, positive reappraisal was a more useful emotion regulation strategy than the others, while the pattern among younger adults was less conclusive. Age-relevant differences in motivation and successful emotion regulatory efforts based on theoretical and empirical literatures are discussed.     

Effects of anxiety,a cognitive secondary task,and expertise on gaze behavior and performance in a far aiming task

ObjectivePrevious studies focused on investigating the separate effects of anxiety, cognitive load, and expertise on perceptual-motor performance, but the combined effects of these factors have not been studied yet. The objective of the current study was to investigate these factors in combination.DesignEleven expert dart players and nine novices performed a dart throwing task in low-anxiety (LA) and high-anxiety (HA) conditions with and without a secondary task.MethodTo manipulate anxiety the dart throwing task was performed low (LA) and high (HA) on a climbing wall with and without the secondary counting backwards task. Performance and efficiency of task execution and gaze behavior were assessed.ResultsThe anxiety manipulation evoked a decrease in dart performance, but only for the novices. Increases in mental effort and dart times and a decrease in response rate on the secondary task were observed for both groups. This shows that there were decreases in processing efficiency with anxiety. Most important, the anxiety-induced decrease in performance for the novices was accompanied by final fixations on the target that were substantially shorter and deviated off the target earlier. The dual task did not affect performance.ConclusionAnxiety affects efficiency and sometimes performance in far aiming tasks. Changes are accompanied by changes in gaze behavior, particularly the final fixation on the target. All in all, findings provide support for Attentional Control Theory as a suitable framework to explain the effects of anxiety, a cognitive secondary task, and expertise in far aiming tasks.     

Cognitive stimulation for healthy older adults through computer-based programs: a review of the literature / Estimulación cognitiva para personas mayores sanas mediante programas computarizados: una revisión de la literatura

Abstract

Cognitive stimulation programs are widely used as a preventive tool for cognitive decline in older adults, as they can favour positive ageing by maintaining older persons’ autonomy and preserving their cognitive functions. Because of this, and due to its potentially easy application on a large scale and at a low cost, the incorporation of technologies for the cognitive stimulation of older adults has become an area of growing interest. This review outlines the advantages and disadvantages of computer-based cognitive stimulation programs aimed at healthy older adults, focusing on aspects that influence their effectiveness and future direction. Twenty-five articles were considered, including original studies, literature reviews and meta-analyses, published between 2013 and 2017. It was concluded that there is a need to generate more randomized studies with active control groups to assess the effectiveness of cognitive stimulation through computer-based programs, as well as develop designs to establish strategies that increase older adults’ adherence and ensure their motivation to carry out these activities.     

Attentional shift by eye gaze requires joint attention: Eye gaze cues are unique to shift attention1

Researchers have demonstrated that attentional shift triggered by gaze direction is reflexive. However, here we show that attentional shift by gaze direction was not always reflexive, but could be modulated by another's perspective. In Experiment 1, a schematic face's line of sight to a peripheral target was obstructed by a vertical barrier located between the face and the target under two conditions. However, the line of sight of the face was clear under another two conditions, in which the barrier was located behind the line of sight by utilizing a depth cue. The gaze cue shifted attention only when the line of sight was not blocked (i.e. joint attention was attained). The arrow cue did not shift attention regardless of the obstruction conditions in Experiment 2. These results suggest that attentional shift by gaze cues, but not arrow cues, involve a higher social cognitive process such as interpretation of the gaze.     

Visual attention in adolescents: Facilitating effects of sport expertise and acute physical exercise

ObjectivesThis study investigated visual attention of adolescent orienteers and physically active adolescents non-practising orienteering both at rest and under acute sub-maximal exercise. It was verified whether the practice of orienteering facilitates the development of visual attentional abilities and whether orienteers, who are used to simultaneously handle physiological and cognitive-attentional loads, may better profit than non-orienteers from the beneficial effects of sub-maximal physical load on processing speed.MethodsBoth the focusing of attention at foveal and parafoveal locations and the orienting of attention at peripheral locations were investigated. In two discriminative reaction time (RT) experiments, a cue of varying size was presented centrally or peripherally and followed by a compound stimulus with local and global target features. The stimulus-onset asynchrony (SOA) varied between a short and a long interval.ResultsIn both experiments, adolescent orienteers and non-practisers showed different patterns of attentional effects. Adolescent orienteers were more similar to young adults in the attentional performance, being better able than non-practisers to perform complex attentional operations involving the intentional zooming of attention in the central visual field and the orienting of the attentional focus in the peripheral visual field. Also, both orienteers and non-orienteers speeded up their performance during exercise, but this facilitation effect was more pronounced for orienteers, who are probably skilled in directing the available resources to task demands.ConclusionsOur results suggest that cognitive expertise represents a key factor in sports that accelerates the development of visual attention and enhances the facilitating effects of physical exercise on attentional performance.     

Metacognitive processes in the self-regulation of performance in elite endurance runners

ObjectiveThis study sought to investigate the dynamics of attentional focus and cognitive control during endurance activity from a metacognitive perspective. The study also intended to examine the situational factors which may influence cognitive strategy use by elite endurance runners.DesignSemi-structured qualitative interviews were utilised.MethodTen elite-level endurance runners were interviewed to explore retrospectively their attentional focus and cognitive strategy use during endurance running.ResultsThe findings revealed that metacognitive strategies such as planning, monitoring, reviewing and evaluating, and metacognitive experiences were fundamental to cognitive control and cognitive strategy use in elite endurance runners. The findings also added to the array of active self-regulatory strategies previously reported in the literature.ConclusionsThese results suggest that metacognitive processes are central to effective cognitive control in elite endurance athletes during running. The findings allowed for the development of an integrative metacognitive framework, which incorporates dimensions of attentional focus. This model may better represent the processes which underpin cognitive control and determine cognitive strategy use in elite athletes during endurance running.     

Time course of selective attention to face regions in social anxiety: eye-tracking and computational modelling

ABSTRACT

We investigated the time course of selective attention to face regions during judgment of dis/approval by low (LSA) and high (HSA) social anxiety undergraduates (with clinical levels on questionnaire measures). The viewers’ gaze direction was assessed and the stimulus visual saliency of face regions was computed, for video-clips displaying dynamic facial expressions. Social anxiety was related to perception of disapproval from faces with an ambiguous smile (i.e. with non-happy eyes), but not those with congruent happy eyes and a smile. HSA observers selectively looked earlier at the eye region, whereas LSA ones preferentially looked at the smiling mouth. Consistently, gaze allocation was less related to visual saliency of the smile for HSA than for LSA viewers. The attentional bias towards the less salient eye region – thus opposing the automatic capture by the smile – suggests that it is strategically driven in HSA individuals, possibly aimed at detecting negative evaluators.
