The role of emotion recognition in reappraisal affordances.

INTRODUCTION: Emotion regulation is essential for psychological well-being. One strategy that is commonly researched is reappraisal. Individual differences regarding the tendency to use reappraisal, as well as its implications for affective experience, were extensively studied. In recent years, interest has emerged in the choice to use reappraisal, based on stimuli properties. Recently, we suggested that reappraisal is related to emotion recognition processes. Emotion recognition (and affective labeling, as an explicit form of emotion recognition) is regarded as a form of emotion regulation, however, the relations between emotion recognition and reappraisal have not been previously investigated. The aim of the current study was to explore the relationship between reappraisal affordances (the opportunities of re-interpretation that are inherent in a stimulus) and emotion recognition. METHOD: For this purpose, we used the Categorized Affective Picture Database, a database that provides data regarding the emotional category of each picture, agreement levels for each category, and intensity ratings. Agreement levels were used to assess the certainty regarding the emotion evoked by the pictures. RESULTS: Findings suggest that reappraisal affordance is predicted by both agreement levels and intensity, in negative pictures alone. In negative pictures, intensity was negatively correlated with the difficulty to reappraise. DISCUSSION: These findings strengthen the hypothesis regarding the relationship between emotion recognition and reappraisal, and provide evidence for the role of emotion recognition in reappraisal affordances.

The contribution of temporal analysis of pupillometry measurements to cognitive research.

Reaction time (RT) is one of the most frequently used measures to detect cognitive processes. When tasks require more cognitive processes/resources, reaction is slower. However, RTs may provide only restricted information regarding the temporal characteristics of cognitive processes. Pupils respond reflexively to light but also to cognitive activation. The more cognitive resources a task requires, the more the pupil dilates. However, despite being able to use temporal changes in pupil size (advanced devices measure changes in pupil diameter with sampling rates of above 1000 samples per second), most past studies using pupil dilation have not investigated temporal changes in pupil response. In the current paper, we discuss the advantage of the temporal approach to analyze pupil changes compared to a more traditional perspective, specifically, singular value methods such as mean value and peak amplitude value. Using data from two recent studies conducted in our laboratory, we demonstrate the differences in findings arising from the various analyses. In particular, we focus on the advantage of temporal analysis in detecting hidden effects, investigating temporal characterizations of the effects, and validating the experimental manipulation.

Rumination, emotional intensity and emotional clarity.

It has been suggested that a high tendency to ruminate presents a deficient emotion regulation. Past research found that people with high tendency to ruminate show sustained attention for negative stimuli and increased negative thinking, which may result in intensified experiences of negative emotions. Moreover, high level of rumination was associated with low emotional understanding. Accordingly, we hypothesized (1) high ruminators (HR) experience more intense emotional reactions than low ruminators (LR) for negative but not positive emotions, (2) LR have higher emotional clarity than HR, and (3) there would be the same pattern of results for brooding but not for reflective pondering. Participants completed a demographic questionnaire, a rumination response style questionnaire, and the Beck Depression Inventory-II. They also rated emotional intensity and identified emotion type for scene pictures from the CAP-D (Categorized Affective Pictures Database). The highest (HR) and lowest (LR) quarters of ruminators were compared on levels of emotional intensity and emotional clarity. We found HR experienced negative emotions more intensely than LR, with no difference for positive emotions. In contrast to our hypothesis, the two groups did not differ in their emotion understanding. This pattern of results was found for brooding but not for reflective pondering. Our research sheds light on the mechanism underlying rumination and emotion regulation.

Neutral stimuli and pupillometric task conflict.

It has been suggested that the interference in the Stroop task arises due to both information conflict (color vs. word meaning) and task conflict (respond to the color vs. read the word). Interestingly, the task conflict (faster responses in the congruent condition compared to the neutral condition) is influenced by the readability of the stimulus. However, behavioral results indicate the influence of the contribution of readability to the task conflict appears only when vocal responses are required. We conducted a Stroop experiment with four readability levels of neutrals. Participants were required to respond manually, and both their response times and pupil dilation were measured. Our results showed the slowest responses for incongruent trials and the fastest responses for congruent trials. However, no differences in responses were found between the readability levels of the neutrals. In contrast, pupil dilation showed the largest dilation in the incongruent trials and smallest dilation in the neutral trials. In addition, the differences between congruent and neutral trials were influenced by the readability of the stimulus. Specifically, unreadable neutral stimuli showed meaningful differences early on, which also remained for longer time compared with readable neutral stimuli. These results are important and can help in specifying new requirements regarding the theory and modeling of the Stroop task; in particular, studies that want to control the neutrality of their neutral trials should take the readability into account.

Numerical cognition: Unitary or diversified system(s)?

Many researchers, including Clarke and Beck, describe the human numerical system as unitary. We offer an alternative view - the coexistence of several systems; namely, multiple systems (general magnitude, parallel individuation, and symbolic) existing in parallel, ready to be activated depending on the task/need. Based on this alternative view, we present an account for the representation of rational numbers.

The transition of object to mental manipulation: beyond a species-specific view of intelligence.

Many attempts have been made to classify and evaluate the nature of intelligence in humans and other species (referred to as the 'g' factor in the former and the G factor in the latter). The search for this essential structure of mental life has generated various models and definitions, yet open questions remain. Specifically, referring to intelligence by overemphasizing the anthropocentric terminology and its ethnocentric overlay is insufficient to account for individual differences and limits its generalizability in biological and cultural contexts. The present work is an attempt to adopt a different perspective on the 'g/G' factor and its measurement. We suggest that intelligence, or g/G, is reflected in a biological capacity that evolved from object manipulation in animals, into mental manipulation in humans, in response to various environmental conditions.

Visual and Auditory Interference Control of Attention in Developmental Dyslexia.

An accumulating body of evidence highlights the contribution of general cognitive processes, such as attention, to language-related skills. OBJECTIVE: The purpose of the present study was to explore how interference control (a subcomponent of selective attention) is affected in developmental dyslexia (DD) by means of control over simple stimulus-response mappings. Furthermore, we aimed to examine interference control in adults with DD across sensory modalities. METHODS: The performance of 14 dyslexic adults and 14 matched controls was compared on visual/auditory Simon tasks, in which conflict was presented in terms of an incongruent mapping between the location of a visual/auditory stimulus and the appropriate motor response. RESULTS: In the auditory task, dyslexic participants exhibited larger Simon effect costs; namely, they showed disproportionately larger reaction times (RTs)/errors costs when the auditory stimulus and response were incongruent relative to RT/errors costs of non-impaired readers. In the visual Simon task, both groups presented Simon effect costs to the same extent. CONCLUSION: These results indicate that the ability to control auditory selective attention is carried out less effectively in those with DD compared with visually controlled processing. The implications of this impaired process for the language-related skills of individuals with DD are discussed.

Do you feel like me or not? This is the question: manipulation of emotional imagery modulates affective priming.

Mood congruity and affective priming have been used to study the effects of affective phenomena on perception. Manipulation of mood is appropriate for investigations of long-term effects while affective priming is limited to short intervals (approximately 300 ms) between a prime and target. However, studying the influence of real-world rapidly changing emotional episodes on perception may fall between the cracks of these methods. This may be caused, inter alia, because emotional episodes are distinguished from mood experiences on one hand, but often last for longer than roughly 300 ms on the other. Thus, it is unclear what experimental approach should be taken to investigate congruency effects triggered by emotional episodes. The present study used a new variation of the evaluation decision task (EDT) combined with a script-driven imagery procedure to investigate a possible congruency relationship between the evaluator's emotional experience at a given time and observable emotional markers of others. We used 180 9-word script-driven imageries as varying valence primes (negative, positive, neutral) and asked participants to imagine themselves in the situation described in the scripts. At the last stage of a trial, all participants were asked to evaluate the mood-positive or negative-of a target face of a child in a photograph. We manipulated the reading interval (4000 ms and 1350 ms) and the subsequent blank interval (300 ms, 5000 ms, and unlimited) until target onset. Prime and target valence were congruent or incongruent. Significant congruency effects were found for both short and long reading intervals and blank intervals. However, in longer blank intervals only the interference effect reached significance. Furthermore, the interference effect was found to be significant mainly in trials beginning with a negative script.

Pupillometric contributions to deciphering Stroop conflicts.

The Stroop task gives rise to two major conflicts: the task conflict (respond to the color vs. read the word) and the information conflict that can result from the stimulus-response compatibility (SRC; difference between two responses) or from the stimulus-stimulus compatibility (SSC; difference between the two contradictive pieces of information). We conducted a two-to-one Stroop experiment (i.e., two colors are mapped to one response key) and measured reaction time and pupil dilation. The results showed clear evidence for informational conflict composed of both the SRC and SSC. In addition, pupil indications for task conflict appeared earlier than indications for both the SSC and the SRC, in line with the theory regarding task conflict.

Perspective taking and emotion: The case of disgust and sadness.

In a recent study (Gilead et al., 2016), perspective taking (PT) was found to have a significant effect on affect ratings of negative pictures compared to neutrals. The current study explores the question whether PT would be affected equally by distinct negative emotions. We used neutral pictures and pictures classified as provoking sadness or disgust, matched for their intensity and arousal. Participants were asked to rate the pictures (on a scale from 1-no emotional reaction, to 5-very strong reaction) from 3 different perspectives - tough, sensitive, or their own - "me". In Experiment 1, all pictures were mixed in the same blocks. In Experiment 2, the sad and disgust pictures were separated into two different blocks (each including neutrals). Both experiments showed significant interaction between PT and emotion. PT was found to be influenced by valence; however, distinct negative emotions were found to affect PT similarly.

Perspective taking in judgment of relative direction tasks.

Mental rotation and visual-spatial perspective taking (VSPT) are two visual-spatial abilities that are highly correlated. Judgment of relative direction (JRD) tasks are commonly used to examine VSPT in conjunction with mental rotation. Moreover, in many studies the task involves switching from an imagined perspective to a sensorimotor perspective at the response phase. The current study employed a JRD task that enabled examination of mental rotation, perspective taking, and perspective switching, separately. In two experiments we found that both perspective taking and perspective switching affected accuracy and response time (RT). Namely, trials with a perspective change larger than 90° (that required perspective taking) were harder than trials with a change smaller than 90° (that required mental rotation), and so were trials that required switching from an imagined perspective to a sensorimotor perspective. Importantly, we suggest that VSPT and mental rotation are dissociable.

CHAP: Open-source software for processing and analyzing pupillometry data.

Pupil dilation is an effective indicator of cognitive and affective processes. Although several eyetracker systems on the market can provide effective solutions for pupil dilation measurement, there is a lack of tools for processing and analyzing the data provided by these systems. For this reason, we developed CHAP: open-source software written in MATLAB. This software provides a user-friendly graphical user interface for processing and analyzing pupillometry data. Our software creates uniform conventions for the preprocessing and analysis of pupillometry data and provides a quick and easy-to-use tool for researchers interested in pupillometry.

Tactile enumeration: A case study of acalculia.

Enumeration is one of the building blocks of arithmetic and fingers are used as a counting tool in early steps. Subitizing-fast and accurate enumeration of small quantities-has been vastly studied in the visual modality, but less in the tactile modality. We explored tactile enumeration using fingers, and gray matter (GM) changes using voxel-based morphometry (VBM), in acalculia. We examined JD, a 22-year-old female with acalculia following a stroke to the left inferior parietal cortex. JD and a neurologically healthy normal comparison (NC) group reported how many fingers were stimulated. JD was tested at several time points, including at acute and chronic phases. Using the sensory intact hand for tactile enumeration, JD showed deficit in the acute phase, compared to the NC group, and improvement in the chronic phase of (1) the RT slope of enumerating up to four stimuli, (2) enumerating neighboring fingers, and (3) arithmetic fluency performance. Moreover, VBM analysis showed a larger GM volume for JD relative to the NC group in the right middle occipital cortex, most profoundly in the chronic phase. JD's performance serves as a first glance of tactile enumeration in acalculia. Pattern-recognition-based results support the suggestion of subitizing being the enumeration process when using one hand. Moreover, the increase in GM in the occipital cortex lays the groundwork for studying the innate and primitive ability to perceive and evaluate sizes or amounts-"sense of magnitude"- as a multisensory magnitude area and as part of a recovery path for deficits in basic numerical abilities.

The effects of training on tactile enumeration.

Subitizing is a fast and accurate process of enumerating small quantities. Whether subitizing carried out in the tactile modality is under debate. We previously found a moderately increasing RT slope from one to four stimuli and a large decrease in RT for five stimuli when using one hand. Yet, a high error rate was observed, making it difficult to determine if the RT pattern found was indeed subitizing. To increase accuracy, we carried out training of the tactile enumeration task using one hand for 6 days. We compared performance in the trained and additional non-trained tasks between two groups-the 6-day training group (6DT) and the non-trained controls (C)-after three periods (1 week, 1 and 6 months after the training of the 6DT group ended). Results showed an increase in accuracy rates for both groups but a decrease in RT for the 6DT group only for the trained task. This RT improvement was present even after 6 months. Importantly, the RT slope of one-hand enumeration did not change after training, showing a moderately increased slope up to four stimuli and a decrease for five stimuli. Our study shows the training long-term effect on tactile enumeration and emphasizes the embodiment of finger counting on enumeration. Two possible enumeration processes are discussed-accelerated counting and subitizing-both based on spatial cues and pattern recognition of familiarized finger-counting patterns.

Attention networks in adolescent anorexia nervosa.

Anorexia nervosa (AN) usually develops during adolescence when considerable structural and functional brain changes are taking place. Neurocognitive inefficiencies have been consistently found in adults with enduring AN and were suggested to play a role in maintaining the disorder. However, such findings are inconsistent in children and adolescents with AN. The current study conducted a comprehensive assessment of attention networks in adolescents with AN who were not severely underweight during the study using an approach that permits disentangling independent components of attention. Twenty partially weight-restored adolescents with AN (AN-WR) and 24 healthy adolescents performed the Attention Network Test which assesses the efficiency of three main attention networks-executive control, orienting, and alerting. The results revealed abnormal function in the executive control network among adolescents with AN-WR. Specifically, adolescents with AN-WR demonstrated superior ability to suppress attention to task-irrelevant information while focusing on a central task. Moreover, the alerting network modulated this ability. No difference was found between the groups in the speed of orienting attention, but reorienting attention to a target resulted in higher error rates in the AN-WR group. The findings suggest that adolescents with AN have attentional abnormalities that cannot be explained by a state of starvation. These attentional dysregulations may underlie clinical phenotypes of the disorder such as increased attention of details.

A novel blink detection method based on pupillometry noise.

Pupillometry (or the measurement of pupil size) is commonly used as an index of cognitive load and arousal. Pupil size data are recorded using eyetracking devices that provide an output containing pupil size at various points in time. During blinks the eyetracking device loses track of the pupil, resulting in missing values in the output file. The missing-sample time window is preceded and followed by a sharp change in the recorded pupil size, due to the opening and closing of the eyelids. This eyelid signal can create artificial effects if it is not removed from the data. Thus, accurate detection of the onset and the offset of blinks is necessary for pupil size analysis. Although there are several approaches to detecting and removing blinks from the data, most of these approaches do not remove the eyelid signal or can result in a relatively large amount of data loss. The present work suggests a novel blink detection algorithm based on the fluctuations that characterize pupil data. These fluctuations ("noise") result from measurement error produced by the eyetracker device. Our algorithm finds the onset and offset of the blinks on the basis of this fluctuation pattern and its distinctiveness from the eyelid signal. By comparing our algorithm to three other common blink detection methods and to results from two independent human raters, we demonstrate the effectiveness of our algorithm in detecting blink onset and offset. The algorithm's code and example files for processing multiple eye blinks are freely available for download ( https://osf.io/jyz43 ).

Weak central coherence in weight-restored adolescent anorexia nervosa: Characteristics and remediation.

OBJECTIVE: Weak central coherence (WCC) refers to a bias towards processing details (local processing) at the expense of paying attention to the bigger picture (global processing). Multiple studies reported WCC in adults with anorexia nervosa (AN). Evidence for WCC in adolescents with AN has been inconsistent. The current study characterizes WCC in weight-restored adolescents with AN (WR-AN) using a direct measure of WCC, and examines whether WCC can be remediated by increasing alertness level-a manipulation that was found useful in enhancing global processing in healthy individuals and clinical populations. METHODS: 40 adolescents (18 WR-AN and 22 healthy adolescents) performed a global/local processing task (Navon task). Auditory alerting cues that elevate alertness level were integrated into the task. RESULTS: Both groups processed global information faster than local information. However, compared with controls, adolescents with WR-AN were better at ignoring an irrelevant bigger picture while attending to details (smaller global interference) and had greater difficulty ignoring irrelevant details while attending to the bigger picture (larger local interference). These differences were attenuated when adolescents with WR-AN were under a state of high alertness. Additionally, the local interference effect was positively correlated with three independent self-report questionnaires assessing eating disorders symptomatology. DISCUSSION: This study suggests that abnormal interference by irrelevant global and local information is a central characteristic of WCC in adolescents with WR-AN that cannot be accounted for by enduring illness or malnourishment. Additionally, this study demonstrates that WCC can be temporarily remediated by encouraging a state of high alertness.

Adjustment of control in the numerical Stroop task.

In the numerical Stroop task, participants are asked to compare the physical sizes (physical task) or numerical values (numerical task) of two digits and ignore the irrelevant dimension. Participants are unable to ignore the irrelevant dimension as indicated by facilitation and interference effects. The literature suggests that there is asymmetry in the ability to adjust control in the physical and numerical tasks. The present study examined this suggestion in two experiments in which we manipulated the proportion of neutral/congruent trials in an experimental block. In addition, we examined the effects of control adjustment on the resolution of the task and informational conflicts. Our results suggest that adjustment of control can be bidirectional and is dependent on task requirements. Moreover, it might be easier to inhibit irrelevant information than to inhibit irrelevant task activation.

Toward an integrative approach to numerical cognition.

In response to the commentaries, we have refined our suggested model and discussed ways in which the model could be further expanded. In this context, we have elaborated on the role of specific continuous magnitudes. We have also found it important to devote a section to evidence considered the "smoking gun" of the approximate number system theory, including cross-modal studies, animal studies, and so forth. Lastly, we suggested some ways in which the scientific community can promote more transparent and collaborative research by using an open science approach, sharing both raw data and stimuli. We thank the contributors for their enlightening comments and look forward to future developments in the field.
