Methods of Overcoming Children's Fears

Forty-eight noninstitutionalized elderly were administered Piaget's Conservation of Surfaces Test. Only 13 subjects were designated as conservers in this content domain. A strong relationship existed between conservation ability and educational attainment, but not between sex and performance, and age and performance. Results indicated that cognitive abilities may be subject to qualitative disorganization in the latter portions of the life-span.     

Spatial Correspondence Learning is Critical for the Sequence Effects of Symbolic Cueing

Attention orienting has been found to be influenced by the previous cueing status in a spatial cueing paradigm. The purpose of this study was to determine whether the cue predictive values or the spatial correspondence learning between cues and targets could influence the sequence effect of symbolic cueing. The findings revealed that the predictive values of arrow or word cues do not lead to different sequence effects, but that visually asymmetrical letter cues, which allow spatial correspondence learning between cues and targets, induce stronger sequence effects than visually symmetrical letter cues. In addition, visually symmetrical directional word cues can induce sequence effects. The results suggest that spatial correspondence learning, although not obligatory, is critical for the sequence effects of symbolic cueing. The findings support the feature‐integration hypothesis, rather than the strategic adjustments account.     

连续和同时线索化条件下的返回抑制容量

利用线索-靶子模式进行了返回抑制容量的两个实验。实验一对外周数个位置连续线索化,实验二对外周数个位置同时线索化。结果表明：(1)在连续线索化条件下,当线索化位置是相邻时,返回抑制容量可以达到4个,当线索化位置是间隔时,返回抑制容量只有1个。(2)在同时线索化条件下．当线索化位置是相邻时,返回抑制容量可以达到3个,当线索化位置是间隔时．返回抑制容量只有1个。结果支持认为存在着两种不同的返回抑制的观点,即一种是弥散性的,其容量较大;另一种是集中性的,其容量只有一个。     

The Effect of Informative and Uninformative Cueing of Attention on Feature Integration

In the present study, the authors observed the effect of informative and uninformative attentional cueing on visual search for targets that were defined by a simple feature or by conjunctions of features. Three different types of attentional cueing were tested in three experiments: peripheral informative cueing, peripheral uninformative cueing, and central informative cueing. Participants showed a greater effect of cueing in detecting a conjunction of features than in detecting unique features only when attention was oriented by either peripheral or central informative cueing. This differential cueing effect was not observed when attention was oriented by peripheral uninformative cueing. The results suggest that voluntarily oriented attention plays a more important role in feature integration than automatically oriented attention does. The results also pose limits on the generalizability of K. A. Briand's (1998) proposal regarding the role of automatically oriented attention in feature integration.     

The Influence of Approach and Avoidance Behavior on Visual Selective Attention

Recent findings indicate that enactment of approach behavior broadens the focus of perceptual attention. The aim of the present study was to examine how approach and avoidance behavior influence visual selective attention. To achieve this, the authors combined approach and avoidance manipulations with a visual precueing task (local vs. global cues preceding either local or global targets). The authors hypothesized that participants with an enactment of approach behavior would show faster attentional orienting with compatible cue-target-relations than in incompatible trials. The results support that enactment of approach behavior leads to faster attentional orienting in compatible trials compared with incompatible trials. Although participants showed significant attentional learning effects across blocks, learning was not enhanced by approach and avoidance manipulations.     

自我面孔对空间注意的调控：来自Posner空间线索范式的证据

利用Posner的空间线索范式,三个实验意在探寻自我面孔作为特殊的刺激对空间注意的调控作用。在实验一中,自我或者熟悉的面孔作为内源性线索出现在视野中央,通过朝左或者朝右来提示目标出现的位置。在实验二（小图）和实验三（大图）中,自我或熟悉的面孔与目标同时呈现,作为与任务无关的刺激出现在视野的左侧或右侧。实验一的结果发现,与熟悉的面孔相比较,自我面孔产生了更大的提示效应。这意味着当自我面孔与任务相关时,对提示位置易化优于熟悉的面孔。与之相反的是,在实验二和实验三中,自我面孔和熟悉的面孔同样捕获目标位置的空间注意。然而,研究并没有发现自我面孔与熟悉面孔在捕获注意上的差异。这一结果也许暗示着在注意捕获的过程中,面孔效应足够大而掩盖了自我效应的出现。这些发现表明自我面孔之所以是具有特殊性的刺激不仅受感知过程的影响,还依赖于与任务的关系。     

Covert orienting of attention in 3-month-old infants: The case of biological motion

Humans attend to different positions in the space either by moving their eyes or by moving covertly their attention. The development of covert attention occurs during the first year of life. According to Colombo’s model of attention (2001), within the first years there is a significant change in infants’ visuo-spatial orienting mechanisms, from a predominantly overt form to a covert orienting starting from 4 to 5 months of life. The use of non-invasive brain imaging techniques can shed light on the origin of such mechanisms. In particular, EEG and ERP studies can directly investigate the neural correlates of covert attention in young infants. The present study investigated the neural correlates of covert attention employing a visuo-spatial cueing paradigm in 3-month-old infants. Infants were presented with a central point-light walker (PLD) followed by a single peripheral target. The target appeared randomly at a position either congruent or incongruent with the walking direction of the cue. We examined infants’ target-locked P1 component and the saccade latencies toward the peripheral target. Results showed that the P1 component was larger in response to congruent than to incongruent targets and saccade latencies were faster for congruent rather than incongruent trials. Moreover, the facilitation in processing sensory information (priming effects) presented at the cued spatial location occurs even before the onset of the oculomotor response, suggesting that covert attention is present before 4 months of age. Overall, this study highlights how ERPs method could help researchers at investigating the neural basis of attentional mechanisms in infants.     

Effects of varying target luminance and cue luminance on attentional effects of spatial cues

Attentional effects of letter cues on target processing were investigated in a bilateral spatial cueing paradigm. Luminance contrast of the cue stimuli and of the target stimuli were both manipulated. Consistent with predictions derived from theoretical models of visual attention, manipulating cue luminance and target luminance had very different effects on performance. In agreement with the dorsal stream attention hypothesis (Marrett et al., 2011) orienting effects were unaffected by changes in cue luminance; but in agreement with the work of Reynolds, Pasternak, and Desimone (2000) and Carrasco, Ling, and Read (2004) orienting effects were strongly modulated by changes in the luminance and perceptual quality of the target. Theoretical implications of the results are considered and the data are explained in terms of a sensory enhancement effect, whereby attention amplifies the neuronal responses for attended stimuli.     

A Review of the Nurtured Heart Approach to Parenting: Evaluation of its Theoretical and Empirical Foundations

The Nurtured Heart Approach to parenting (NHA; Glasser & Easley, 2008) is summarized and evaluated in terms of its alignment with current theoretical perspectives and empirical evidence in family studies and developmental science. Originally conceived and promoted as a behavior management approach for parents of difficult children (i.e., with behavior disorders), NHA is increasingly offered as a valuable strategy for parents of any children, despite a lack of published empirical support. Parents using NHA are trained to minimize attention to undesired behaviors, provide positive attention and praise for compliance with rules, help children be successful by scaffolding and shaping desired behavior, and establish a set of clear rules and consequences. Many elements of the approach have strong support in the theoretical and empirical literature; however, some of the assumptions are more questionable, such as that negative child behavior can always be attributed to unintentional positive reinforcement by parents responding with negative attention. On balance, NHA appears to promote effective and validated parenting practices, but its effectiveness now needs to be tested empirically.     

线索在多媒体学习中的作用

线索在多媒体学习中作为一种重要的教学设计形式,具有引导注意、组织和整合信息的功能。综述已有研究发现,线索具有引导学习者加工特定位置信息、忽视无关信息干扰的功能;在特定条件下帮助学习者整合图-文信息,并且提高学习者的学习效果;但对于线索信息组织功能尚缺少充分而有力的证据。关于线索对学习效果的影响,大部分研究证实线索能够促进学习。但是由于线索的多样性以及学习材料的复杂性,线索能否有效地提高学习效果仍然存在争议。从认知负荷理论视角综述发现,线索加入并没有明显降低学习者感知到的主观认知负荷;从知觉加工视角而言,线索作为突显的刺激会吸引学习者的注意,从而简化学习者在知觉加工阶段的视觉搜索。未来研究仍然需要关注以下问题:(1)线索是否真的被学习者所注意和加工?(2)重视学习材料多样性比较和不同线索类型差异探讨,(3)关注学习者经验影响,(4)如何在教学设计上保证线索的有效性。     

The effect of spatial organization of targets and distractors on the capacity to selectively memorize objects in visual short-term memory

We conducted a series of experiments to explore how the spatial configuration of objects influences the selection and the processing of these objects in a visual short-term memory task. We designed a new experiment in which participants had to memorize 4 targets presented among 4 distractors. Targets were cued during the presentation of distractor objects. Their locations varied according to 4 spatial configurations. From the first to the last configuration, the distance between targets’ locations was progressively increased. The results revealed a high capacity to select and memorize targets embedded among distractors even when targets were extremely distant from each other. This capacity is discussed in relation to the unitary conception of attention, models of split attention, and the competitive interaction model. Finally, we propose that the spatial dispersion of objects has different effects on attentional allocation and processing stages. Thus, when targets are extremely distant from each other, attentional allocation becomes more difficult while processing becomes easier. This finding implicates that these 2 aspects of attention need to be more clearly distinguished in future research.     

Assessing the impact of verbal and visuospatial working memory load on eye-gaze cueing

Observers tend to respond more quickly to peripheral stimuli that are being gazed at by a centrally presented face, than to stimuli that are not being gazed at. While this gaze-cueing effect was initially seen as reflexive, there have also been some indications that top-down control processes may be involved. Therefore, the present investigation employed a dual-task paradigm to attempt to disrupt the putative control processes involved in gaze cueing. Two experiments examined the impact of working memory load on gaze cueing. In Experiment 1, participants were required to hold a set of digits in working memory during each gaze trial. In Experiment 2, the gaze task was combined with an auditory task that required the manipulation and maintenance of visuospatial information. Gaze cueing effects were observed, but they were not modulated by dual-task load in either experiment. These results are consistent with traditional accounts of gaze cueing as a highly reflexive process.

Development and Validation of the Children's Assertiveness Inventory

The development and validation of the Children's Assertiveness Inventory are reported. Psychometric properties of the scale are detailed for the normal samples of grade school children and one sample of socially withdrawn children. Initial analyses indicate that the scale possesses high test-retest reliability and acceptable stability over time. Further, it adequately discriminates between normal and withdrawn samples, has acceptable convergent and discriminant validity, and possesses a meaningful factor structure. The potential research and clinical utility of the scale is discussed, and important social and developmental issues affecting the expression of assertiveness in children are addressed.

Social attention across borders: A cross-cultural investigation of gaze cueing elicited by same- and other-ethnicity faces

The gaze-cueing effect is a robust phenomenon which illustrates how attention can be shaped by social factors. In four experiments, the present study explored the interaction between the ethnic membership of the participant and that of the face providing the gaze cue. Firstly, we aimed to further investigate the differential impact of White, Black, and Asian faces on the gaze-cueing effect in White individuals. Secondly, we aimed to explore, for the first time, the impact of faces belonging to different ethnicities on gaze cueing in Chinese participants. The results allowed to rule out alternative accounts and showed that White participants exhibit a gaze-cueing effect for White and Asian faces, but not for Black faces, consistent with previous studies. As regards Chinese participants, the overall findings suggested a stronger gaze-cueing effect for White faces than for Asian faces. The results are discussed with reference to differences in the perceived social status of the various groups, pointing to the need of taking into account different cultural contexts.     

In the presence of conflicting gaze cues,fearful expression and eye-size guide attention

Humans are social beings that often interact in multi-individual environments. As such, we are frequently confronted with nonverbal social signals, including eye-gaze direction, from multiple individuals. Yet, the factors that allow for the prioritisation of certain gaze cues over others are poorly understood. Using a modified conflicting gaze paradigm, we tested the hypothesis that fearful gaze would be favoured amongst competing gaze cues. We further hypothesised that this effect is related to the increased sclera exposure, which is characteristic of fearful expressions. Across three experiments, we found that fearful, but not happy, gaze guides observers’ attention over competing non-emotional gaze. The guidance of attention by fearful gaze appears to be linked to increased sclera exposure. However, differences in sclera exposure do not prioritise competing gazes of other types. Thus, fearful gaze guides attention among competing cues and this effect is facilitated by increased sclera exposure – but increased sclera exposure per se does not guide attention. The prioritisation of fearful gaze over non-emotional gaze likely represents an adaptive means of selectively attending to survival-relevant spatial locations.     

The role of spatial attention and other processes on the magnitude and time course of cueing effects

We are quite often exposed to multiple objects present in the visual scene, thus attentional selection is necessary in order to selectively respond to the relevant information. Objects can be selected on the basis of the location they occupy by orienting attention in space. In this paper, we review the evidence showing that attention can be oriented in space either endogenously, on the basis of central cues, predictive of the relevant location, or exogenously, automatically triggered by the salient properties of visual stimuli (peripheral cues). Several dissociations observed between orienting on the basis of the two types of cues have led to the conclusion that they do not represent just two modes of triggering the orienting of the very same attentional mechanism, but rather they modulate processing differently. We present a theoretical framework according to which endogenous predictive cues facilitate target processing by orienting attention, thus amplifying processing at the attended location. In contrast, apart from attentional orienting, peripherally presented discrepant cues might trigger additional cue-target event-integration and event-segregation processes, which modulate processing in a different way, thus leading to cueing effects that are exclusively triggered by peripheral cues.     

A novel variation of the Stroop task reveals reflexive supremacy of peripheral over gaze stimuli in pro and anti saccades

A long-standing controversy in social attention debates whether gaze-of-another induces reflexive shifts of one’s own attention. In attempting to resolve this controversy, we utilized a novel Stroop task, the PAT Stroop, in which pro- and anti-saccade (PAT) responses are made to competing gaze and peripheral stimuli. The first experiment demonstrated a “Stroop effect” for peripheral stimuli, i.e. peripheral distractors interfered with gaze triggers, but gaze distractors did not interfere with peripheral triggers. These results were replicated in the second experiment, which also negated the possibility that the mere display and practice of the “clean PAT” influenced the results. Thus, the use a new PAT Stroop task demonstrated reflexive supremacy of peripheral stimuli over gaze stimuli. This novel variant of the Stroop task demonstrated similar characteristics to the classic color naming Stroop - i.e. an asymmetrical pattern, and again showed the utility and versatility of stoop-like tasks in probing mental tasks.
