Attentional capture by items that match episodic long-term memory representations

A remarkable ability of the human visual system is the implementation of attentional control settings (ACSs) that govern what stimuli capture or hold attention. We provide evidence that ACSs can be specified by episodic long-term memory representations. In all experiments, participants memorized 30 images of objects that they then monitored for in an attention task, inducing an episodic-based ACS. In Experiments 1a and 1b, only studied cues in a cueing task captured attention. We confirmed these cueing effects reflect capture by testing for inhibition of return in Experiment 2a, and controlled for perceptual masking by cues in Experiment 2b. In Experiment 3 we determined that ACSs are specifically supported by episodic retrieval, by dividing studied images into two sets and designating one as the targets in a rapid serial visual presentation task: Only target-set matching distractors produced a spatial blink (captured attention). These results extend our understanding of the representations specifying ACSs.     

Coaching cues in amateur boxing: An analysis of ringside feedback provided between rounds of competition

Feedback is commonly employed to enhance motor learning and performance. While numerous studies have investigated the causal effects of feedback on motor learning, an analysis of real-time feedback provided during training and competitive sporting environments is lacking. Therefore, the feedback provided by 12 boxing coaches to athletes between rounds of the 2015 Australian Boxing Championships was recorded and transcribed. The feedback statements were then analyzed according to three feedback variables that have been shown to be critical for optimizing performance: Attentional focus (external, internal, neutral), autonomy support (autonomy-supportive, controlling, neutral), and feedback valence (positive, negative, neutral). Collectively, 445 feedback statements provided during 25 bouts, of which 14 were won and 11 were lost, were analyzed for each of the three categories. Coaches provided on average 8 feedback statements per round. Excluding neutral statements, coaches delivered more internal (15%) compared with external focus feedback (6%), more controlling (53%) compared with autonomy-supportive feedback (6%), and more positive (29%) relative to negative feedback (12%). Furthermore, during winning bouts coaches delivered less internal (12% vs. 19%), less controlling (48% vs. 58%), and more positive (36% vs. 18%) feedback, when compared with losing bouts. These results demonstrate for the first time the type and frequency of feedback delivered during amateur boxing bouts. While these findings may or may not reflect causal relationships, it is interesting that feedback that has been found to enhance motor performance was more often used during winning rather than losing bouts.     

Relationship between sustained,orientated, divided,and selective attention and simulated aviation performance: Training & pressure effects

The present study examined how different characteristics of visual attention are related to flying ability. Eighty participants completed one of four attentional tests designed to assess sustained attention (SUSTAIN), attentional orienting (ORIENT), divided attention (DIVIDE) or selective attention (SELECT). Median splits were used to create low and high groups. After completing training, participants executed simulated landings under conditions of high anxiety. For the DIVIDE test, there were significant group differences in: (i) landing ability after training and (ii) the effects of anxiety. The high DIVIDE group had lower root mean square (RMS) errors at the end of training and were less affected by anxiety as compared to the low DIVIDE group. For the ORIENT and SELECT tests, there were significant group effects for training but not for anxiety. The high groups for these tests displayed lower RMS errors following training. There were no group differences for the SUSTAIN test. The results suggest that a test of divided attention may be useful for operational assessment of pilots.     

The coupling between spatial attention and other components of task-set: A task-switching investigation

Is spatial attention reconfigured independently of, or in tandem with, other task-set components when the task changes? We tracked the eyes of participants cued to perform one of three digit-classification tasks, each consistently associated with a distinct location. Previously we observed, on task switch trials, a substantial delay in orientation to the task-relevant location and tendency to fixate the location of the previously relevant task—“attentional inertia”. In the present experiments the cues specified (and instructions emphasized) the relevant location rather than the current task. In Experiment 1, with explicit spatial cues (arrows or spatial adverbs), the previously documented attentional handicaps all but disappeared, whilst the performance “switch cost” increased. Hence, attention can become decoupled from other aspects of task-set, but at a cost to the efficacy of task-set preparation. Experiment 2 used arbitrary single-letter cues with instructions and a training regime that encouraged participants to interpret the cue as indicating the relevant location rather than task. As in our previous experiments, and unlike in Experiment 1, we now observed clear switch-induced attentional delay and inertia, suggesting that the natural tendency is for spatial attention and task-set to be coupled and that only quasi-exogenous location cues decouple their reconfiguration.     

Carry-over of attentional settings between distinct tasks: A transient effect independent of top-down contextual biases

Top-down attentional settings can persist between two unrelated tasks, influencing visual attention and performance. This study investigated whether top-down contextual information in a second task could moderate this “attentional inertia” effect. Forty participants searched through letter strings arranged horizontally, vertically, or randomly and then made a judgement about road, nature, or fractal images. Eye movements were recorded to the picture search and findings showed greater horizontal search in the pictures following horizontal letter strings and narrower horizontal search following vertical letter strings, but only in the first 1000 ms. This shows a brief persistence of attentional settings, consistent with past findings. Crucially, attentional inertia did not vary according to image type. This indicates that top-down contextual biases within a scene have limited impact on the persistence of previously relevant, but now irrelevant, attentional settings.     

Towards a framework of cognitive processes during competitive golf using the Think Aloud method

ObjectivesMost research to date that has investigated cognitive processes in golf using the Think Aloud (TA) method has analysed data deductively and using statistical methods. Such an approach, however, can lead to potentially relevant data being overlooked and assumes that a priori coding schemes are valid reflections of a phenomenon. Therefore, to enable the generation of novel insights, this study sought to qualitatively explore cognitive processes in golf by inductively analysing TA data captured during competition.MethodSeventeen adolescent golfers (male n = 16; female n = 1, M handicap = 5.43) were asked to verbalise their thoughts while playing a 6-hole competitive round of golf. Data were analysed thematically in relation to the pre-shot and post-shot phases by each author independently, with the final findings produced collaboratively and through the use of trustworthiness procedures.ResultsCognitive processes during the pre-shot and post-shot phases were each captured by six themes. Some cognitive processes were consistently evident across shots, while others differed depending on the context. Before shots, the players consistently reported: monitoring; planning; and situational appraisals. Additionally, shots were followed by: monitoring; reviewing, evaluating, and planning; and situational appraisals. Before and after shots, the players also described context-specific: affective responses; distraction; and psychological skills.ConclusionsThe study demonstrated the benefits of moving beyond deductively analysing and quantifying cognitions by using an inductive approach to analyse TA data. The findings extend current knowledge by illustrating the dynamic and often deliberative process that occurs during the decision making process in golf.     

Sensitivity to lateral information on a perceptual word identification task in French third and fifth graders

This study aimed at examining sensitivity to lateral linguistic and nonlinguistic information in third and fifth grade readers. A word identification task with a threshold was used, and targets were displayed foveally with or without distractors. Sensitivity to lateral information was inferred from the deterioration of the rate of correct word identification when displayed with distractors. Results show that the two reader groups were sensitive to both right and left lateral information. The area of sensitivity to this information was more extended for the identification of easy words than difficult words. Examination of the detrimental effect of distractors suggests that in both third and fifth graders, the impact of lateral information on foveal processing is the result of a general distraction effect, but also of linguistic processing whose nature remains to be clarified.     

Role of frontal cortex in attentional capture by singleton distractors

The role of frontal cortex in selective attention to visual distractors was examined in an attentional capture task in which participants searched for a unique shape in the presence or absence of an additional colour singleton distractor. The presence of the additional singleton was associated with slower behavioural responses to the shape target, and a greater neural signal in inferior frontal gyrus. To investigate the involvement of cognitive control functions of the frontal lobes in the capture of attention by the additional singletons, we measured the effect of the additional singleton in a context of either low or high working memory load. Whereas behavioural capture was unaffected by the level of load on working memory, greater activity associated with the presence of the additional singleton was observed in inferior frontal gyrus, but only under high load. This effect was greater in participants who experienced greater capture. We argue that the role of inferior frontal gyrus in selective attention is to detect potential sources of distraction.     

Positive affectivity and attentional control moderate the link between negative affectivity and depressed mood

Research and theory suggest that deficits in trait positive affectivity (PA) and in capacity for executive control of attention (i.e., attentional control or AC) may each intensify risk for depressive symptoms associated with high trait negative affectivity (NA). In contrast, high levels of PA and AC should protect against that risk. However, prospective tests of such predictions are rare. Furthermore, if PA and AC both modulate NA-related risk, it remains to be seen if those effects are independent and complementary or if they operate in an overlapping manner. This study assessed baseline temperament and change in depressed mood across one month in a sample of 125 adolescents. Results supported both PA and AC as modulators of NA’s association with changes in depressed mood. Furthermore, results suggested that these modulating effects are largely non-overlapping and complementary, such that when both PA and AC are low, high NA predicts increases in depressed mood. In contrast, high NA predicts decreases in depressed mood when both PA and AC are high. Limitations of these findings, directions for future research, and implications for prevention are discussed.     

Predicting internalizing symptoms over a two year period by BIS,FFFS and attentional control

Identifying risk factors for the development of internalizing disorders is of major importance. In this context, behavioral inhibition (BIS), the fight-flight-freeze-system (FFFS), and attentional control (AC) have been proposed as being possible risk factors for both anxiety disorders and depression. Even though related cross-sectionally, it is still unclear whether these factors are precursors for internalizing disorders. In this longitudinal study, 1811 participants (aged 12–15) completed questionnaires on BIS/FFFS, AC, and internalizing symptoms at pretest and at two year follow-up. Supporting the alleged importance of BIS/FFFS and AC in the development of internalizing symptoms, BIS/FFFS and AC showed predictive value for anxiety and depression symptoms at two year follow-up. For anxiety symptoms this predictive value was not independent of the level of symptoms at pretest. For depression symptoms, AC showed predictive value over and above pretest level of depression symptoms. In the context of early detection of at risk adolescents, results suggest that screening of current anxiety and depression symptoms is most relevant in addition to a focus on AC for the screening of depression. However, it cannot be ruled out that at a further extended follow-up also BIS/FFFS might show independent predictive value for symptoms of anxiety and/or depression.
