When unpleasantness meets feminines: a behavioural study on gender agreement and emotionality.

The emotional connotation of words is known to affect word and sentence processing. However, the when and how of the interaction between emotion and grammar are still up for debate. In this behavioural experiment, 35 female university students read noun phrases (NPs) composed by a determiner and a noun in their L1 (Spanish), and were asked to indicate if the NPs were grammatically correct (elmasc camareromasc) or not (*lafem tornillomasc; i.e. a gender agreement task). The type of gender (arbitrary/natural), the emotionality (unpleasant/neutral), and the gender class (feminine/masculine) of the nouns were manipulated. We found an overall grammaticality effect, responses being faster in grammatically correct trials than in incorrect ones. However, the effects of emotionality and gender class varied depending on gender type. For arbitrary gender, the grammaticality effect was greater in feminine nouns than in masculine nouns and independent of emotionality. For natural gender, the grammaticality effect interacted with gender class and emotionality, this effect only emerging in unpleasant stimuli for feminine nouns. Our results reveal that it is possible to find emotional effects at the behavioural level in an intrinsically grammatical task. Yet, these effects depend on gender properties like the type of gender and the gender class.

So far but yet so near: Examining the buffering effect of perceived social support on the psychological impact of Spanish lockdown.

The main objective of this study was to examine the moderating or buffering effect of social support (SS) perceived by university students on the psychological impact of lockdown on mental health. Specifically, a total of 826 participants (622 women) completed an online survey that included standardized measures of anxiety (Generalised Anxiety Disorder-7), depression (Patient Health Questionnaire-9), and irritability (Brief Irritability Test), as well as measures of stressors, perceived SS, and self-perceived change in mental health. The results of hierarchical regression analyses suggest that SS contributes toward attenuating the negative impact of academic stressors, general overload, and interpersonal conflict on the indicators of psychological well-being; however, moderation analysis only confirms the buffering effect for symptoms of anxiety. In conclusion, it is suggested that SS networks need to be strengthened as a basic means of protecting health and well-being during unexpected disasters.

Unraveling the Mystery About the Negative Valence Bias: Does Arousal Account for Processing Differences in Unpleasant Words?

Many studies have found that the emotional content of words affects visual word recognition. However, most of them have only considered affective valence, finding inconsistencies regarding the direction of the effects, especially in unpleasant words. Recent studies suggest that arousal might explain why not all unpleasant words elicit the same behavior. The aim of the present research was to study the role of arousal in unpleasant word recognition. To do that, we carried out an ERP experiment in which participants performed a lexical decision task that included unpleasant words which could vary across three levels of arousal (intermediate, high, and very high) and words which were neutral in valence and had an intermediate level of arousal. Results showed that, within unpleasant words, those intermediate in arousal evoked smaller LPC amplitudes than words that were high or very high in arousal, indicating that arousal affects unpleasant word recognition. Critically, arousal determined whether the effect of negative valence was found or not. When arousal was not matched between unpleasant and neutral valenced words, the effect of emotionality was weak in the behavioral data and absent in the ERP data. However, when arousal was intermediate in both unpleasant and neutral valenced words, larger EPN amplitudes were reported for the former, pointing to an early allocation of attention. Interestingly, these unpleasant words which had an intermediate level of arousal showed a subsequent inhibitory effect in that they evoked smaller LPC amplitudes and led to slower reaction times and more errors than neutral words. Our results highlight the relevance that the arousal level has for the study of negative valence effects in word recognition.

A Study on the Psychological Wound of COVID-19 in University Students.

An increasing number of studies have addressed the psychological impact of the COVID-19 crisis on the general population. Nevertheless, far less is known about the impact on specific populations such as university students, whose psychological vulnerability has been shown in previous research. This study sought to examine different indicators of mental health in university students during the Spanish lockdown; we also analyzed the main sources of stress perceived by students in relation to the COVID-19 crisis, and the coping strategies adopted when faced with the situation. Data was collected from 932 students (704 women) through a web-based platform. Measures of anxiety (i.e., GAD-7), depression (PHQ-9), irritability, and self-perceived change in mental health were administered, as well as ad hoc measures of stressors and coping strategies. Results indicated that students experienced considerable psychological problems during the confinement, with higher rates of emotional difficulties in women and undergraduate students than in men and postgraduates, respectively. Psychological distress was mainly related to several specific domains of stressors, as perceived by the participants: academic future, task overload, worsening of interpersonal conflicts, and restrictions in pleasant social contact; and far less related to the spread of the disease and its consequences for physical health. As regards coping strategies, both reframing skills and daily routines were shown to be the most effective. A path-analysis model integrating stressors, coping, and mental health revealed that coping strategies partially mediated the effect of stressors on psychological health. In general, results suggest that students' psychological health was substantially affected by the COVID-19 situation and that the academic and relational changes were the most notable sources of stress. This study reinforces the need to monitor and promote mental health in university students to boost resilience in times of crisis. Our results on effective coping strategies may inform preventive programs aimed at helping students to deal with challenges like the COVID-19 pandemic.

Processing gender agreement errors in pleasant and unpleasant words: An ERP study at the sentence level.

In this study we examine the extent to which aspects such as the emotionality coded in words may interfere with the processing of gender agreement errors in a sentence grammaticality judgement task. We follow the methodological pattern of our previous experiments, using consistently the same kind of structure and task (gender agreement) and only emotional (pleasant vs unpleasant) words, in an attempt to clarify whether neural correlates and performance show similar patterns in positive and negative words. We found an emotional effect in the N400 time window for unpleasant adjectives as well as the classic grammaticality effects in the left anterior negativity (LAN) and the P600 components. Overall, our results confirm those of our previous studies in that the LAN and the P600 grammaticality effects are not influenced by the emotional valence of moderately arousing pleasant and unpleasant words, showing that during sentence reading morphosyntactic error detection seems to be encapsulated.

EmoFinder: The meeting point for Spanish emotional words.

We present here emoFinder ( http://usc.es/pcc/emofinder ), a Web-based search engine for Spanish word properties taken from different normative databases. The tool incorporates several subjective word properties for 16,375 distinct words. Although it focuses particularly on normative ratings for emotional dimensions (e.g., valence and arousal) and discrete emotional categories (fear, disgust, anger, happiness, and sadness), it also makes available ratings for other word properties that are known to affect word processing (e.g., concreteness, familiarity, contextual availability, and age of acquisition). The tool provides two main functionalities: Users can search for words matched on specific criteria with regard to the selected properties, or users can obtain the properties for a set of words. The output from emoFinder is highly customizable and can be accessed online or exported to a computer. The tool architecture is easily scalable, so that it can be updated to include word properties from new Spanish normative databases as they become available.

Representing the consequences of our actions trial by trial: Complex and flexible encoding of feedback valence and magnitude.

In the last decades it has been shown that two components of the event-related potentials (ERPs), the feedback-related negativity (FRN) and the P300, reflect the evaluation of the outcomes of a given course of action. Within the reinforcement learning theory, the prevailing interpretation of the relationship between FRN and P300 is the classical "independent coding model". This model proposes that the FRN is only sensitive to feedback valence whereas the P300 is only sensitive to feedback magnitude. However, these predictions have recently been challenged and the question remains unsolved. The goal of the present study is to shed light on the effects of outcome valence and magnitude on the FRN and the feedback-P300. The electroencephalographic (EEG) activity was recorded while participants performed a perceptual discrimination task with two levels of difficulty, in which they could receive large or small rewards and penalties. We used receiver operating characteristics (ROC) analyses, which allowed us to analyze the relationship between the outcomes and EEG on a trial-by-trial basis. The results reveal that both components, which are contingent on feedback presentation, are sensitive to outcome valence. Regarding magnitude, this only affects the feedback P300, and only in conjunction with difficulty. Finally, we found that task difficulty has the opposite effect on these components, both in their latencies and discriminability. Our results suggest that the FRN and the feedback-P300 in fact reflect different performance monitoring processes in a flexible way that depends on the behavioral context.

EEG activity represents the correctness of perceptual decisions trial-by-trial.

Performance monitoring is an executive function, which we depend on for detecting and evaluating the consequences of our behavior. Although event related potentials (ERPs) have revealed the existence of differences after correct and incorrect decisions, it is not known whether there is a trial-by-trial representation of the accuracy of the decision. We recorded the electroencephalographic activity (EEG) while participants performed a perceptual discrimination task, with two levels of difficulty, in which they received immediate feedback. Receiver Operating Characteristic (ROC) analyses were used to reveal two components that convey trial-by-trial representations of the correctness of the decisions. Firstly, the performance monitoring-related negativity (PM-N), a negative deflection whose amplitude is higher (more negative) after incorrect trials. Secondly, the performance monitoring-related positivity (PM-P), a positive deflection whose amplitude is higher after incorrect trials. During the time periods corresponding to these components, trials can be accurately categorized as correct or incorrect by looking at the EEG activity; this categorization is more accurate when based on the PM-P. We further show that the difficulty of the discrimination task has a different effect on each component: after easy trials the latency of the PM-N is shorter and the amplitude of the PM-P is higher than after difficult trials. Consistent with previous interpretations of performance-related ERPs, these results suggest a functional differentiation between these components. The PM-N could be related to an automatic error detection system, responsible for fast behavioral corrections of ongoing actions, while the PM-P could reflect the difference between expected and actual outcomes and be related to long-term changes in the decision process.

El uso de sonidos como estímulos en el condicionamiento clásico electrodérmico humano / The use of sounds as stimuli in human electrodermal classical conditioning

Tradicionalmente, en el estudio del condicionamiento clásico humano se emplearon descargas eléctricas y ruidos intensos como estímulos incondicionados aversivos. Sin embargo, el uso de este tipo de estímulos plantea una serie de problemas de carácter ético y metodológico. Consecuentemente, en trabajos recientes se comprobó que podía obtenerse condicionamiento sustituyendo el habitual ruido blanco por un sonido cuya aversividad se derivaba más de su contenido semántico que de su intensidad. Sin embargo, los estímulos empleados en estos trabajos plantean, a su vez, una serie de problemas relacionados tanto con la complejidad técnica requerida para su grabación y posterior edición como con la replicación de los resultados. En este estudio se pretende superar dichos problemas utilizando sonidos del IADS ("International Affective Digitized Sounds") como estímulos condicionados e incondicionados en un procedimiento de condicionamiento clásico electrodérmico. Los resultados mostraron una rápida disminución en la amplitud de las respuestas que se interpretó en términos de una habituación de la reacción de orientación. Se comentan las limitaciones encontradas y se propone la posibilidad de utilizar la metodología empleada en este estudio en futuros trabajos (AU)

Traditionally, human classical conditioning studies used electric shocks and loud noises as aversive unconditioned stimuli. However, the use of such stimuli raises a number of methodological and ethical issues. Consequently, in recent works it was found that conditioning could be obtained by replacing the usual white noise with a sound whose aversivity could be derived from its semantic content rather than its intensity. However, the stimuli used in these studies raise, in turn, a number of problems related to both technical complexity required for recording and further editing as difficulties in replication of the results. The present work suggests the possibility of overcoming these problems using sounds selected from the IADS (International Affective Digitized Sounds) as conditioned and unconditioned stimuli on electrodermal classical conditioning procedure. The results showed a rapid decrease in the amplitude of the responses that was interpreted in terms of a habituation of the orienting reaction. We discuss the limitations found, and propose the possibility of using the methodological approach employed in this study in future work (AU)

Decision-making in the ventral premotor cortex harbinger of action.

Although the premotor (PM) cortex was once viewed as the substrate of pure motor functions, soon it was realized that it was involved in higher brain functions. By this it is meant that the PM cortex functions would better be explained as motor set, preparation for limb movement, or sensory guidance of movement rather than solely by a fixed link to motor performance. These findings, together with a better knowledge of the PM cortex histology and hodology in human and non-human primates prompted quantitative studies of this area combining behavioral tasks with electrophysiological recordings. In addition, the exploration of the PM cortex neurons with qualitative methods also suggested its participation in higher functions. Behavioral choices frequently depend on temporal cues, which together with knowledge of previous outcomes and expectancies are combined to decide and choose a behavioral action. In decision-making the knowledge about the consequences of decisions, either correct or incorrect, is fundamental because they can be used to adapt future behavior. The neuronal correlates of a decision process have been described in several cortical areas of primates. Among them, there is evidence that the monkey ventral premotor (PMv) cortex, an anatomical and physiological well-differentiated area of the PM cortex, supports both perceptual decisions and performance monitoring. Here we review the evidence that the steps in a decision-making process are encoded in the firing rate of the PMv neurons. This provides compelling evidence suggesting that the PMv is involved in the use of recent and long-term sensory memory to decide, execute, and evaluate the outcomes of the subjects' choices.

Attentional Processing and Recall of Emotional Words / Procesamiento atencional y recuerdo de palabras emocionales

Three experiments were carried out in order to evaluate the attention paid to words of different emotional value. A dual-task experimental paradigm was employed, registering response times to acoustic tones which were presented during the reading of words. The recall was also evaluated by means of an intentional immediate recall test. The results reveal that neither the emotional valence nor the arousal of words on their own affected the attention paid by participants. Only in the third experiment, in which words belonging to two specific semantic categories (sexual and threatening) were used, did females show significantly higher RTS for threatening words. Nonetheless, significant differences were observed in the immediate subsequent recall for the different types of words in all three experiments. Future studies should take into account: a) the differential status of words and pictures to capture attention, b) the differential influence of valence, as well as arousal, on recall of emotional words, and c) the differential effects of the semantic category on the attention paid to these words by males and females.

Se llevaron a cabo tres experimentos para evaluar la atención a palabras de diferente valor emocional. Se trabajó con un paradigma experimental de doble tarea, registrando los tiempos de respuesta ante tonos, los cuales fueron presentados durante la lectura de palabras. El recuerdo también fue evaluado a través de una prueba de memoria intencional inmediata. Los resultados revelan que ni el valor, ni la excitación de las palabras, afectan la atención de los participantes. Solamente, en el tercer experimento, en el que las palabras pertenecieron a dos categorías semánticas específicas (sexual y riesgo de muerte) las mujeres mostraron significativamente mayor RTS ante palabras amenazadoras. No obstante, se observaron diferencias significativas en el recuerdo inmediato posterior, para los diferentes tipos de palabras en los tres experimentos. Los estudios futuros deben tener en cuenta: ( a) la situación diferencial de las palabras e imágenes para captar la atención, (b) la influencia diferencial de valencia, así como la excitación, en el recuerdo de palabras emocionales y (c) los efectos diferenciales de la categoría semántica de la atención prestada a estas palabras de hombres y mujeres.

Affective ratings of sound stimuli.

This article present the Spanish assessments of the 111 sounds included in the International Affective Digitized Sounds (IADS; Bradley & Lang, 1999b). The sounds were evaluated by 159 participants in the dimensions of valence, arousal, and dominance, using a computer version of the Self-Assessment Manikin (Bradley & Lang, 1994). Results are compared with those obtained in the American version of the IADS, as well as in the Spanish adaptations of the International Affective Picture System (P. J. Lang, Bradley, & Cuthbert, 1999; Moltó et al., 1999) and the Affective Norms for English Words (Bradley & Lang, 1999a; Redondo, Fraga, Padrón, & Comesaña, 2007).

The Spanish adaptation of ANEW (affective norms for English words).

This article presents the Spanish adaptation of the Affective Norms for English Words (ANEW; Bradley & Lang, 1999). The norms are based on 720 participants' assessments of the translation into Spanish of the 1,034 words included in the ANEW. The evaluations were done in the dimensions of valence, arousal and dominance using the Self-Assessment Manikin (SAM). Apart from these dimensions, five objective (number of letters, number of syllables, grammatical class, frequency and number of orthographic neighbors) and three subjective (familiarity, concreteness and imageability) psycholinguistic indexes are included.
