Both animal studies and studies using deep brain stimulation in humans have demonstrated the involvement of the subthalamic nucleus (STN) in motivational and emotional processes; however, participation of this nucleus in processing human emotion has not been investigated directly at the single-neuron level. We analyzed the relationship between the neuronal firing from intraoperative microrecordings from the STN during affective picture presentation in patients with Parkinson’s disease (PD) and the affective ratings of emotional valence and arousal performed subsequently. We observed that 17% of neurons responded to emotional valence and arousal of visual stimuli according to individual ratings. The activity of some neurons was related to emotional valence, whereas different neurons responded to arousal. In addition, 14% of neurons responded to visual stimuli. Our results suggest the existence of neurons involved in processing or transmission of visual and emotional information in the human STN, and provide evidence of separate processing of the affective dimensions of valence and arousal at the level of single neurons as well.

AbstractClinical motor and non-motor effects of deep brain stimulation (DBS) of the subthalamic nucleus (STN) in Parkinson's disease (PD) seem to depend on the stimulation site within the STN. We analysed the effects of the position of the stimulation electrode within the motor STN on subjective emotional experience, expressed as emotional valence and arousal ratings to pictures representing primary rewards and aversive fearful stimuli in 20 PD patients. Patients’ ratings from both aversive and erotic stimuli matched the mean ratings from a group of 20 control subjects at similar position within the STN. Patients with electrodes located more posteriorly reported both valence and arousal ratings from both the rewarding and aversive pictures as more extreme. Moreover, posterior electrode positions were associated with a higher occurrence of depression at a long-term follow-up. This brain–behavior relationship suggests a complex emotion topography in the motor part of the STN. Both valence and arousal representations overlapped and were uniformly arranged anterior-posteriorly in a gradient-like manner, suggesting a specific spatial organization needed for the coding of the motivational salience of the stimuli. This finding is relevant for our understanding of neuropsychiatric side effects in STN DBS and potentially for optimal electrode placement.

Previous studies have not yet investigated sufficiently the relationship between visual processing and negative emotional valence intensity, which is the degree of a dimensional component included in emotional information. In Experiment 1, participants performed a visual search task with three valence levels: neutral (control) and high- and low-intensity negative emotional valence stimuli (both angry faces). Results indicated that response times for high-intensity negative emotional valence stimuli were shorter than low-intensity ones. In Experiment 2, participants were asked to detect a target face among successively presented faces. Facial stimuli were the same as in Experiment 1. Results revealed that accuracy was higher for angry faces than for neutral faces. However, performance did not differ as a function of negative emotional valence intensity. Overall, the task performance differences between negative emotional valence intensities were observed in visual search, but not in attentional blink. Therefore, negative emotional valence intensity likely contributes to the process of efficient visual information encoding.

Deception is a complex and cognitively draining dyadic process that simultaneously involves cognitive and emotional processes, both of which demand/capture attentional resources. However, few studies have investigated the allocation of attentional resources between cognitive and emotional processes during deception. The current study presented facial expressions of different valences to 36 participants. While an electroencephalogram was recording, they were asked to make either truthful or deceptive gender judgments according to preceding cues. The results showed that deceptive responses induced smaller P300 amplitudes than did truthful responses. Task-irrelevant negative emotional information (TiN) elicited larger P300 amplitudes than did task-irrelevant positive emotional information (TiP). Furthermore, the results showed that TiN elicited larger LPP amplitudes than did TiP in deceptive responses, but not in truthful ones. The results suggested that attentional resources were directed away to deception-related cognitive processes and TiN, but not TiP, was consistently able to compete for and obtain attentional resources during deception. The results indicated that TiN could disrupt with deception and may facilitate deception detection.

The present study shows that the impact of emotional states on creativity depends on individual emotional characteristics as well as the type of task used. The results found during the last 30 years diverge concerning relationships between emotion and creative cognition. For this reason, we conducted a study to explore whether the impact of emotional states on creative potential is moderated by individuals’ emotional traits. Using a multivariate approach, we measured (1) emotional valence and arousal level of participants after an emotional induction, (2) emotional traits (e.g., alexithymia, emotional expressivity, affective intensity, emotional idiosyncrasy), and (3) quantity, originality, and valence of generated ideas in two distinct divergent thinking tasks. Participants were 107 undergraduate university students. Regression analyses confirm our hypothesis showing that the impact of emotional states on creative performance is not uniform, but depends on participants’ emotional state and emotion-related traits. For example, we observed that the more individuals had difficulty with emotional information and the higher their level of arousal, the less they generated pleasant ideas. Several processes such as arousal regulation may explain the observed results.

Objectives: An experiment was conducted to explore how emotional valence of contexts and exposure frequency of novel words affect second language (L2) contextual word learning. Methodology: Chinese native speakers who learned English in a formal classroom setting were asked to read English paragraphs with different emotional valence (positive, negative or neutral) across five different days. These paragraphs were embedded with pseudowords. During this learning process, form recognition test and meaning recall test were carried out for these pseudowords. Data and analysis: Data were analyzed using mixed-model ANOVA. Accuracy for each task was compared among the three kinds of emotional contexts. Findings/Conclusions: In the form recognition test, the accuracy in the negative context was higher than in the positive and neutral contexts, and the pseudowords were acquired much earlier. In the meaning recall test, the accuracy in the positive and negative contexts was higher than that in the neutral context. Accuracy increased gradually with the increase of exposure frequency of the pseudowords. More importantly, we found that less exposure times were needed for emotional context relative to neutral context in contextual word learning. Originality: This may be the first study to explore the influence of emotional valence and exposure frequency on L2 contextual word learning. Significance/Implications: This study underlined the importance of emotional information in L2 contextual word learning and contributed to the understanding of how emotional information and exposure frequency functions in this learning process.

AbstractIt is unknown how self-relevance is dependent on emotional salience. Emotional salience encompasses an individual's degree of attraction or aversion to emotionally-valenced information. The current study investigated the interconnection between self and salience through the evaluation of emotional valence and self-relevance. 56 native Dutch participants completed a questionnaire assessing valence, intensity, and self-relevance of 552 Dutch nouns and verbs. One-way repeated-measures ANCOVA investigated the relationship between valence and self, age and gender. Repeated-measures ANCOVA also tested the relationship between valence and self with intensity ratings and effects of gender and age. Results showed a significant main effect of valence for self-relevant words. Intensity analyses showed a main effect of valence but not of self-relevance. There were no significant effects of gender and age. The most important finding presents that self-relevance is dependent on valence. These findings concerning the relationship between self and salience opens avenues to study an individual's self-definition.

Only a few birds besides domestic pigeons and poultry can be described as domesticated. Therefore, keeping a pet bird can be challenging, and the human-avian relationship will have a major influence on the quality of this cohabitation. Studies that focus on characterizing the owner-bird relationship generally use adapted cat/dog scales which may not identify its specific features. Following a sociological approach, a concept of human-animal relationship was developed leading to three types of human-animal relationship (impersonal, personal, and close personal). This concept was used to develop a 21-item owner-bird-relationship scale (OBRS). This scale was applied to measure the relationship between pet bird owners (or keepers) (n = 1,444) and their birds in an online survey performed in Germany. Factor analysis revealed that the relationship between owner and bird consisted of four dimensions: the tendency of the owner to anthropomorphize the bird; the social support the bird provides for the owner; the empathy, attentiveness, and respect of the owner toward the bird; and the relationship of the bird toward the owner. More than one quarter of the German bird owners of this sample showed an impersonal, half a personal, and less than a quarter a close personal relationship to their bird. The relationship varied with the socio-demographic characteristics of the owners, such as gender, marital status, and education. This scale supports more comprehensive quantitative research into the human-bird relationship in the broad field of human-animal studies including the psychology and sociology of animals as well as animal welfare and veterinary medicine.

This chapter introduces the field of animal studies as an interdisciplinary scholarly endeavor to understand the relationship humans have with other animals. That relationship is mapped into five major categories, reflected in the titles of each of the handbook’s five parts: “Animals in the Landscape of Law, Politics and Public Policy”; “Animal Intentionality, Agency, and Reflexive Thinking”; “Animals as Objects in Science, Food, Spectacle and Sport”; “Animals in Cultural Representations”; and “Animals in Ecosystems.” The chapters in each part are summarized and key issues in the “animal question” are explicated. Chapter topics include animals in research, entertainment, law, political theory, public policy, agency, tourism and ecology. Concluding remarks include an appeal for altruistic coexistence for all beings in the earth’s ecosystem.
