Involuntary attention in the absence of visual awareness

ABSTRACT

Previous studies have found a dissociation between voluntary attention and awareness. Here, we examined the relationship between involuntary attention and awareness. We presented a masked cue such that participants were unaware of the cue. This was followed by a search array, for which participants detected the presence of a shape target. Even though the cue was task irrelevant and unconscious, we observed faster reaction times when either the cue’s location or colour was congruent with shape target. We conclude an unconscious stimulus can elicit both space- and feature-based attention. These results provide further evidence for the dissociation between attention and consciousness.     

奖赏预期对选择性注意的影响——基于客体和空间的注意的区别

为了探究奖赏预期对选择性注意的影响,结合金钱激励延迟任务和双矩形范式,通过两个实验分别考察了奖赏预期的有无以及高低对选择性注意的影响。实验结果表明,在有奖赏预期的情况下,选择性注意更快,奖赏预期的有无对基于空间的注意影响区别不大,但奖赏预期几乎消除了基于客体的注意效应。在低奖赏预期条件下,基于客体和空间的注意均存在;而高奖赏预期条件下,基于空间的注意仍然存在,基于客体的注意几乎被消除了。结果表明奖赏预期可以影响选择性注意,并对基于空间和客体的注意产生不同影响。     

Individual and relational contributions to parallel and joint attention in infancy

Objective

This study examined the contributions of maternal bids for joint attention, relationship quality, and infant characteristics, to individual differences in infants’ parallel and joint attention.

Method

Fifty-two 10-month-olds and their mothers were assessed in order to investigate concurrent predictors of infant parallel attention, responding to joint attention, and initiating joint attention.

Results

Parallel attention was predicted by infants’ higher mental development, low expression of negative emotionality, and maternal entertaining behaviors. Responding to joint attention was marginally predicted by total maternal bids for joint attention. Initiating joint attention was predicted by the infants’ low expression of negative emotionality, as well as marginally predicted by fewer maternal teaching behaviors.

Conclusion

These results further the understanding of the factors influencing infant parallel as well as joint attention.

No templates for rejection: a failure to configure attention to ignore task-irrelevant features

ABSTRACT

Knowing the colour of an upcoming target allows one to bias attention towards objects of that colour. It is far less clear whether knowing the colour of an up-coming distractor can allow one to suppress attention to items of that colour. Arita, Carlisle, and Woodman (2012) suggest that people can create a template for rejection. However, the method used in Arita et al. may have allowed people to adopt a strategy of internally generating a positive cue for the target colour or target hemifield. Here we use a method very similar to theirs, but manipulate the display layouts and the number of un-cued colours in ways that should thwart such strategies. Across three experiments, we find a negative cuing benefit only in a very special circumstance that encourages a strategic shift to internally generating a positive cue (the same circumstance used by Arita et al.). We conclude that people are unable to use a negative feature-cue on a trial-by-trial basis to suppress attention to upcoming distractors, and attribute the finding in Arita et al. to a strategic shift rather than a template for rejection.     

Computerized attention retraining for individuals with elevated health anxiety

Background and Objectives: Current cognitive-behavioral theorists conceptualize hypochondriasis as excessive health anxiety (HA). Growing evidence suggests that elevated HA is associated with attentional bias (AB) toward potential health-threat information. Design: This study aimed to examine the effects of attention retraining among individuals with elevated HA, using the established attention modification programs (AMP) designed to train participants to disengage attention from ideographically chosen health-threat words. Methods: Thirty-six randomly assigned individuals with elevated HA completed eight twice-weekly sessions of the AMP (n = 18) or the attention control condition (ACC; n = 18). Results: Despite using the well-established AMP protocol widely used within the field of anxiety disorders, we did not find evidence for change in AB following training. Further, AMP did not outperform ACC in reducing HA and other relevant emotional symptoms. However, both AMP and ACC evidenced overall significant symptom reduction in most of the outcome measures, including overall HA, anxiety sensitivity, general depression and anxiety, and somatic complaints. Conclusions: Further research is needed to better understand the effects and mechanisms of AMP as a possible cognitive intervention for HA.     

Staying and Returning dynamics of young children's attention

In this paper, we decompose selective sustained attending behavior into components of continuous attention maintenance and attentional transitions and study how each of these components develops in young children. Our results in two experiments suggest that changes in children's ability to return attention to a target locus after distraction (“Returning”) play a crucial role in the development of selective sustained attention between the ages of 3.5–6 years, perhaps to a greater extent than changes in the ability to continuously maintain attention on the target (“Staying”). We further distinguish Returning from the behavior of transitioning attention away from task (i.e., becoming distracted) and investigate the relative contributions of bottom-up and top-down factors on these different types of attentional transitions. Overall, these results (a) suggest the importance of understanding the cognitive process of transitioning attention for understanding selective sustained attention and its development, (b) provide an empirical paradigm within which to study this process, and (c) begin to characterize basic features of this process, namely its development and its relative dependence on top-down and bottom-up influences on attention.

Research Highlights

• Young children exhibited an endogenously ability, Returning, to preferentially transition attention to task-relevant information over task-irrelevant information.
• Selective sustained attention and its development were decomposed into Returning and Staying, or task-selective attention maintenance, using novel eye-tracking-based measures.
• Returning improved between the ages of 3.5–6 years, to a greater extent than Staying.
• Improvements in Returning supported improvements in selective sustained attention between these ages.

     

不同注意条件下的空间－数字反应编码联合效应

考察在无线索、内源性线索与外源性线索时不同符号数字在注意与非注意条件下的空间－数字的反应编码联合效应（Spatial Numerical Association of Response Codes,简称SNARC效应）。采用1到9的中文与阿拉伯数字为材料,以判断数字奇偶为任务。实验结果表明：⑴无线索时注意条件下阿拉伯和中文数字都出现了SNARC效应,而非注意条件下则都没有出现,并且受影响的主要是较大的数字（8、9）;⑵外源性线索和内源性线索时,我们得到一个逐渐递减的SNARC效应,受影响的也主要是较大的数字（8、9）。在内源性线索的注意条件阿拉伯和中文数都有SNARC效应,而在非注意条件只有阿拉伯数有SNARC效应;在外源性线索的注意条件只有阿拉伯数有SNARC效应,而在非注意条件阿拉伯和中文都没有SNARC效应,说明外源性注意的影响比内源性注意更大,中文数字所受的影响比阿拉伯数字更大。     

Endogenous shifts of attention cause distortions in the perception of space: Reviewing and examining the attentional repulsion effect

ABSTRACT

The functioning of spatial attention and its effects on visual processing are typically studied using chronometric and accuracy measures of behaviour. However, a growing body of literature has studied the attentional repulsion effect (ARE). Simply put, when attention is focused on one location in the visual field, stimuli appearing nearby the attended location are perceived as being located further away from the attended location than they physically are. The ARE is particularly compelling, as it is best explained by considering the receptive field properties of visual cells, thus allowing for more direct comparisons between behaviour and neural functioning. Nonetheless, most research testing the ARE has manipulated spatial attention exogenously. Furthermore, for studies that have explored endogenous attention and the ARE, empirical evidence is conflicting. Therefore, the aim of the current study was to address this inconsistency by testing the effect of voluntary attention on spatial repulsion using an optimal operationalization of endogenous attention. Centrally presented, highly informative double-cues were used to shift attention, and placeholders were included in the display to help anchor attention. Overall, we observed strong spatial repulsion effects when attention was shifted endogenously, providing compelling evidence that voluntary deployments of attention can cause perceptual distortions of space.     

基于空间与基于物体的视觉选择的交互作用

已有的大量实验证据表明,基于空间和基于物体的注意成分都存在于视觉系统中,两者并不是相互排斥的。然而,过去对基于空间和基于物体的视觉选择的研究是分别在非常不同的实验范式下进行的,从而导致对两种注意成分之间的内在关系的理论争论。本文介绍近十年来在单任务范式下对基于空间和基于物体的注意的内在关系的研究,并指出未来的研究应该重点从神经生理水平上揭示两种注意成分之间的交互作用关系。     

When motor attention improves selective attention: The dissociating role of saliency

There is evidence that preparing and maintaining a motor plan (“motor attention”) can bias visual selective attention. For example, a motor attended grasp biases visual attention to select appropriately graspable object features (Symes, Tucker, Ellis, Vainio, & Ottoboni, 2008). According to the biased competition model of selective attention, the relative weightings of stimulus-driven and goal-directed factors determine selection. The current study investigated how the goal-directed bias of motor attention might operate when the stimulus-driven salience of the target was varied. Using a change detection task, two almost identical photographed scenes of simplistic graspable objects were presented flickering back and forth. The target object changed visually, and this change was either high or low salience. Target salience determined whether or not the motor attended grasp significantly biased visual selective attention. Specifically, motor attention only had a reliable influence on target detection times when the visual salience of the target was low.     

The effects of spatial configuration on preschoolers' attention strategies,selective attention,and incidental learning

This study investigated the effects of spatial arrangement on preschool children's selective attention and incidental learning. Three‐ and four‐year old children were shown a multi‐coloured box designated as a ‘special place’ containing miniature chairs and models of animals. One category of objects were designated as relevant and one as irrelevant. Relevant items were placed in each of the apparatus' corners, in the middle of its walls, or in two corners and in the middle of two walls. Findings revealed that children shown relevant items in corners demonstrated the greatest number of correct relocations for relevant items while those shown relevant items in the middle of the walls showed the greatest number of correct relocations for irrelevant items. Findings also suggest that for both age groups, the ability to recall relevant items may have been independent of their ability to demonstrate a selective attention strategy.

Suppression in object-based attention

This study examines suppression in object-based attention in three experiments using an object-based attention task similar to Egly, R., Driver, J., & Rafal, R. D. (1994. Shifting visual attention between objects and locations: Evidence from normal and parietal lesion subjects. Journal of Experimental Psychology: General, 123(2), 161–177. doi:10.1037/0096-3445.123.2.161) with the addition of a distractor. In Experiment 1 participants identified a target object at one of four ends of two rectangles. The target location was validly cued on 72% of trials. The remaining 28% were located on the same or a different object. Sixty-eight percent of trials also included a distractor on one of the two objects. Experiment 1 failed to show suppression when a distractor was present, but did demonstrate the spread of attention across the attended object when no distractor was present. Experiment 2 added a mask to the paradigm to make the task more difficult and engage suppression. When suppression was engaged in the task, data showed suppression on the unattended (different) object, but not on the attended (same) object. Experiment 3 replicated findings from Experiment 1 and 2 using a within participants design. Findings are discussed in relation to the role of suppression in visual selective attention.     

Rapid allocation of temporal attention in the attentional blink paradigm

How fast can information of a first target (T1) in a rapid serial visual presentation be used for top-down allocation of attention in time? A valid cue about the temporal position of a second target (T2) was integrated into T1. The data show that 100 ms after T1 onset, T2 was identified better than without cue, raising the conditional T2 performance. T1 apparently triggers a facilitative effect of attention, known from other paradigms such as peripheral cueing.     

积极情绪对视觉注意的调节及其机制

在积极心理学思潮的推动下, 已有研究不但发现积极情绪扩展了空间和时间注意范围、增加了注意灵活性, 而且发现在积极情绪下个体对积极刺激表现出了注意偏向。对这些现象, 先前研究主要以积极情绪的扩展与建构理论、情绪信息等价说等理论来加以解释。但这些理论主要从宏观上强调情绪信息对注意加工的启动或积极情绪对注意资源分布的调节, 并不能清楚地揭示积极情绪对注意调节的内在机制。神经生化机制研究发现, 这些现象可能与多巴胺系统对注意控制能力的调节以及积极情绪对初级视觉皮层编码的调节有关。将来研究者可以基于不同的种类的注意选择和注意模型来进一步拓展积极情绪对注意调节的研究, 同时注重对其机制的探讨和理论的整合与创新。     

内源性注意和外源性注意的ERP研究

内源性注意和外源性注意反映注意指向与集中的自上而下和自下而上的加工。大量事件相关电位的ERP研究考察了内源性注意和外源性注意的神经活动机制。内源性注意诱发了早期N1成分和晚期P300成分,是否诱发P1成分的研究结果不尽一致;外源性注意加强了N1成分、P1成分以及P300成分。研究还表明内源性注意和外源性注意是两种独立的注意系统,以不同的方式影响着脑内的信息加工
