Processing eye-gaze and aligning one’s own attention with the gaze direction of others (gaze following) is a crucial ability and it underpins several cognitive and affective mechanisms. However, we know little about how this gaze following operates in realistic scenarios in adults. The present study addresses this gap by presenting naturalistic sce...

Introduction With ageing there are changes in the ability to orient attention, which affect more endogenous than exogenous orienting. However, orienting attention by the gaze direction of others shares characteristics of both exogenous and endogenous attention and it is unclear how it is affected by ageing. Being able to orient attention by the gaz...

Introduction Time is a crucial abstract construct, allowing us to perceive the duration of events. Working memory (WM) plays an important role in manipulating and storing the different features of environmental stimuli, including temporal features. Different brain structures, including the dorsolateral prefrontal cortex, are involved in time proces...

Age-related decline in episodic memory is often linked to structural and functional changes in the brain. Here, we investigated how these alterations might affect functional connectivity during memory retrieval following exposure to emotional stimuli. Using functional magnetic resonance imaging (fMRI), participants viewed images with varying emotio...

Psychological safety has recently emerged as a central construct, strictly implicated in mental health and emotional well-being. The Neuroception of Psychological Safety Scale (NPSS) is the first scale designed to assess feelings of psychological safety from a multidimensional perspective. However, the robustness of its factorial structure requires...

A visual stimulus that is divided in harmonic proportions is often judged as more pleasant than others. This is well known by artists that often used two main types of geometric harmonic patterns: symmetry and the golden ratio. Symmetry refers to the property of an object to have two similar halves, whereas the golden ratio consists of dividing an...

The golden ratio, also known as Phi (ϕ ≈ 1.618034), attracted the interest of mathematicians, artists, and intellectuals for many centuries, probably from when it was discovered in human anthropometry. Even in recent times, researchers found the presence of the golden ratio in Renaissance paintings and aesthetic preferences. The reasons behind the...

Growing old involves changes in physical, psychological, and cognitive functions. Promoting physical and mental health has become one of the priorities for an aging population. Studies have demonstrated the benefits of engaging in regular physical activity. Here, we aimed to understand the relationships between physical activity and working memory...

Objective: Loneliness has been associated to a greater risk of cognitive decline and dementia in older individuals. However, evidence on whether this association also exists for older individuals who complain of cognitive problems is limited. We conducted a survey to examine the association between subjective cognitive decline in the working memor...

Introduction Several studies have shown that the working memory is sensitive to temporal variations. We used a new visuospatial working memory task, the “Time Squares Sequences,” to investigate whether implicit variations in stimuli presentation time affect task performance. Methods A total of 50 healthy participants saw two sequences (S1 and S2)...

Orienting attention by social gaze cues shares some characteristics with orienting attention by non-social arrow cues, but it is unclear whether they rely on similar neural mechanisms. The present ALE-meta-analysis assessed the pattern of brain activation reported in 40 single experiments (18 with arrows, 22 with gaze), with a total number of 806 p...

Bisection tasks are commonly used to assess biases and asymmetries in visuospatial attention in both patients and neurologically intact individuals. In these tasks, participants are usually asked to identify the midpoint and manually bisect a horizontal line. Typically, healthy individuals tend to show an attention processing advantage for the left...

The ten contributions of the current Special Issue on “Symmetry in Cognition and Emotion” represent different and original contributions to this topic. The new evidence spans from addressing whether the attentional blink can be elicited by internal events to the role of the fronto-parietal network. The review contributions address the effect of emo...

Under many conditions, emotional information is processed with priority and it may lead to cognitive conflict when it competes with task-relevant information. Accordingly, being able to ignore emotional information relies on cognitive control. The present perspective offers an integrative account of the mechanism that may underlie emotional conflic...

Individuals are better at recognizing faces of their own age group (Own Age Bias) but it is unclear whether this bias occurs also for emotional faces and to what extent is affected by loneliness. Young individuals (N = 235) completed an age categorization task on faces of young and old individuals showing neutral, happy, and angry expressions. Afte...

Healthy ageing has been associated with a bias toward positive information and greater psychological well-being. However, to what extent this positivity bias also applies to prioritizing positive information under emotional competition is unclear. Old and young adults performed a word-face interference task, in which they responded to the valence o...

Previous research shows an Own Age Bias in young adults, which has been attributed to the greater contact with, and/or to the greater salience of, others who belong to the same group. Importantly, there is some evidence that when emotional faces are used such effect is eliminated. Considering that the Own Age Bias relies both on social contacts and...

The human middle-temporal region MT+ is highly specialized in processing visual motion. However, recent studies have shown that this region is modulated by extraretinal signals, suggesting a possible involvement in processing motion information also from non-visual modalities. Here, we used functional MRI data to investigate the influence of retina...

In two experiments using a Rapid Serial Visual Presentation (RSVP) we investigated how emotional and neutral faces (T1) modulate temporal attention for a following neutral face (T2). Typically, performance for T2 is spared when T2 immediately follows T1 (lag 1 sparing) but it is impaired when T2 is presented within 500 ms from T1 (Attentional Blink...

The cerebellum has a homogeneous structure and performs different computational functions such as modulation/coordination of the communication between cerebral regions, and regulation/integration of sensory information. Albeit cerebellar activity is generally associated with motor functions, several recent studies link it to various cognitive funct...

Spinal cord injuries (SCI) are disruptive neurological events that severly affect the body leading to the interruption of sensorimotor and autonomic pathways. Recent research highlighted SCI-related alterations extend beyond than the expected network, involving most of the central nervous system and goes far beyond primary sensorimotor cortices. Th...

Background: A large body of research has shown brain asymmetries in spatial attention. Specifically, there is an attention-processing advantage for the left visual field in healthy, right-handed subjects, known as “pseudoneglect.” Several studies have revealed that emotions modulate this basic spatial phenomenon, but the direction of the effect is...

The AB refers to the performance impairment that occurs when visual selective attention is overloaded through the very rapid succession of two targets (T1 and T2) among distractors by using the rapid serial visual presentation task (RSVP). Under these conditions, performance is typically impaired when T2 is presented within 200–500 ms from T1 (AB)....

Children shift their attention based on the gaze direction of another person but it is unclear whether they prioritize only the gaze of fearful faces over neutral ones or more generally, the gaze of emotional faces. School children performed a gaze-cueing task, in which central, non-predictive happy, angry, and neutral face-cues were briefly presen...

The fronto-parietal network is involved in top-down and bottom-up processes necessary to achieve cognitive control. We investigated the role of asymmetric enhancement of the left dorsolateral prefrontal cortex (lDLPFC) and right posterior parietal cortex (rPPC) in cognitive control under conditions of emotional conflict arising from emotional distr...

There is evidence that emotional stimuli impair attention for subsequent stimuli when presented in rapid visual succession. We investigated whether non-visible emotions of hybrid faces showing either happy or afraid expressions only in their Low Spatial Frequencies (LSF) and neutral expressions in their High Spatial Frequencies (HSF) modulate tempo...

Adaptive behaviour requires the ability to process goal-relevant events at the expense of irrelevant ones. However, perception of a relevant visual event can transiently preclude access to consciousness of subsequent events — a phenomenon called attentional blink (AB). Here we investigated involvement of the left dorsolateral prefrontal cortex (DLP...

This study is a direct replication of gaze-liking effect using the same design, stimuli and procedure. The gaze-liking effect describes the tendency for people to rate objects as more likeable when they have recently seen a person repeatedly gaze toward rather than away from the object. However, as subsequent studies show considerable variability i...

The performance impairment (attentional blink, AB) on a second target (T2) when it is presented within 200-500 ms after a first target (T1) during rapid serial visual presentation (RSVP) is typically attributed to resource depletion. The AB does not occur when targets appear in immediate sequence (sparing). Recently, this account has been challenge...

Direction of eye gaze cues spatial attention, and typically this cueing effect is not modulated by the expression of a face unless top-down processes are explicitly or implicitly involved. To investigate the role of cognitive control on gaze cueing by emotional faces, participants performed a gaze cueing task with happy, angry, or neutral faces und...

Supporting Information Experiment 2. (DOCX)

The role of cognitive control mechanisms in reducing interference from emotionally salient distractors was investigated. In two experiments, participants performed a flanker task in which target-distractor affective compatibility and cognitive load were manipulated. Differently from past studies, targets and distractors were presented at separate s...

There is evidence of a preference for visual symmetry. This is true from mate selection in the animal world to the aesthetic appreciation of works of art. It has been proposed that this preference is due to processing fluency, which engenders positive affect. But is visual symmetry pleasant? Evidence is mixed as explicit preferences show that this...

Humans are quicker to detect reflectional than rotational or translational symmetry, despite the fact that these patterns are equally regular. We were interested in the neural correlates of these perceptual effects. Participants viewed random, reflection, rotation, and translation patterns while we recorded EEG from the scalp. Half the participants...

Symmetry has a central role in visual art, it is often linked to beauty, and observers can detect it efficiently in the lab. We studied what kind of fast and automatic responses are generated by visual presentation of symmetrical patterns. Specifically, we tested whether a brief presentation of novel symmetrical patterns engenders positive affect u...

A reflection between a pair of contours is more rapidly detected than a translation, but this effect is stronger when the contours are closed to form a single object compared to when they are closed to form 2 objects with a gap between them. That is, grouping changes the relative salience of different regularities. We tested whether this manipulati...

It is possible that the neural mechanisms that detect symmetry are linked to those that produce positive affect. We conducted a set of behavioural and electrophysiological studies designed to investigate the nature of this putative connection. First, we used the Implicit Association Test (IAT) to measure implicit preference for visual regularity. O...

Symmetry and beauty are strongly linked, but is the positive response to visual symmetry automatic? We used the Implicit Association Test (IAT) to measure the valence of visual regularities in the absence of overt judgments. In our first experiment, participants classified dot patterns as random or having an axis of reflection, and words as positiv...

We report a new perceptual distortion of neutral facial expressions induced by the immediate dynamic perceptual history. In Experiment 1, participants evaluated the facial expression on the last frame of videoclips showing morphs from a happy or angry expression to neutral, and consistently judged these as slightly angry in the happy-to-neutral con...

Artists have always considered symmetry and beauty to be related, while animals are known to prefer symmetrical mates. It seems that the neural mechanisms that detect symmetry are linked to those which mediate positive affect. However, the nature of this link is uncertain. It could be that symmetry automatically elicits a positive response. Alterna...

Empirical evidence shows an effect of gaze direction on cueing spatial attention, regardless of the emotional expression shown by a face, whereas a combined effect of gaze direction and facial expression has been observed on individuals' evaluative judgments. In 2 experiments, the authors investigated whether gaze direction and facial expression af...

Empirical evidence obtained with neutral stimuli has shown that selective attention relies on working memory functions as distractor processing occurs under conditions of high but not of low working memory load. We investigated whether these findings also hold for affectively valent distractors. In three experiments, participants completed the orig...

Recently, using a conditional pronunciation task, De Houwer and Randell (2004) reported evidence of affective priming effects only when pronunciation depended on the semantic category of targets. Although these findings support the notion that spreading of activation is the mechanism underlying affective priming effects, an explanation in terms of...

The Iowa Gambling Task (IGT) is widely used to assess decision making under conditions of uncertainty in clinical as well as in nonclinical populations. However, there is still debate as to whether normal performance at this task relies on implicit, emotion-based processes that are independent of working memory. To clarify the role of working memor...

The claim that semantic activation is an automatic process was recently called a myth, on the basis of the finding that if letter search is performed on a prime word, semantic priming effects on response time are eliminated, whereas repetition effects are preserved. The absence of semantic activation, however, cannot be validly inferred from the la...

Understanding the relationship between emotional responses and physiological activity has always been an important topic for research on emotion. In the past decades researchers have tried to identify the specific patterns of autonomic nervous system (ANS) activity associated with different emotions (e.g., Ax, 1953; Ekman, Levenson, & Friesen, 1983...

A pacman type video-game paradigm is introduced for the manipulation of appraisals in an ongoing active-coping task. Differences in current. appraisal conceptions and their implications for experimental approaches to the manipulation of appraisals are discussed. Furthermore, the advantages of using concurrent physiological measures are outlined. Th...

The meaning of spontaneous skin conductance activity, and its relevance to appraisal theory, are examined. Spontaneous skin conductance activity is hypothesised to reflect task engagement, and thus to be correlated with appraisals of problem-focused coping potential. In a within-subjects design, subjects solved anagrams in which task difficulty was...

Electrodermal activity has been studied in patients with focal brain injury mainly to evaluate hypotheses about the relative contribution of the two cerebral hemispheres to emotional processes. Theoretical proposals on this issue originated from the clinical observations indicating different emotional reactions following damage in either hemisphere...

Both sensory and imaginal defects have been reported in unilateral neglect, but their assessment based on the description of famous squares can be difficult in a clinical setting. The O'clock Test is an alternative tool for revealing imaginal defects. Our aim was to demonstrate imaginal neglect in patients with left heminattention. Ten patients wer...
