In light of Lang’s differentiation of the aversive and the approach system – and assumptions stemming from attachment theory – this study investigates the role of the approach or caregiving system for processing infant emotional stimuli by comparing IAPS pictures, infant pictures, and videos. IAPS pictures, infant pictures, and infant videos of positive, neutral, or negative content were presented to 69 mothers, accompanied by randomized startle probes. The assessment of emotional responses included subjective ratings of valence and arousal, corrugator activity, the startle amplitude, and electrodermal activity. In line with Lang’s original conception, the typical startle response pattern was found for IAPS pictures, whereas no startle modulation was observed for infant pictures. Moreover, the startle amplitudes during negative video scenes depicting crying infants were reduced. The results are discussed with respect to several theoretical and methodological considerations, including Lang’s theory, emotion regulation, opponent process theory, and the parental caregiving system.

Perceptual Systems

Three factors that have transformed perceptual research in the last fifty years are the digital computer, single-unit electrophysiology, and molecular biology. Amongst the developments in which members of the Experimental Psychology Society have been central are: the recognition of the role of optic flow in spatial vision; the demonstration that our perceptual systems contain parallel pathways extracting different information from the sensory array; the identification of specific detectors that can be selectively adapted in psychophysical experiments; and the transfer of the concepts of fourier analysis from audition to vision. The history of Opponent Process Theory offers an example where experimental psychologists have been misled by too simple an interpretation of physiological recordings.

Abstract. As the criticism of the definition of the phenotype (i.e., clinical diagnosis) represents the major focus of the Research Domain Criteria (RDoC) initiative, it is somewhat surprising that discussions have not yet focused more on specific conceptual and procedural considerations of the suggested RDoC constructs, sub-constructs, and associated paradigms. We argue that we need more precise thinking as well as a conceptual and methodological discussion of RDoC domains and constructs, their interrelationships as well as their experimental operationalization and nomenclature. The present work is intended to start such a debate using fear conditioning as an example. Thereby, we aim to provide thought-provoking impulses on the role of fear conditioning in the age of RDoC as well as conceptual and methodological considerations and suggestions to guide RDoC-based fear conditioning research in the future.

Recognizing user emotions while they watch short-form videos anytime and anywhere is essential for facilitating video content customization and personalization. However, most works either classify a single emotion per video stimuli, or are restricted to static, desktop environments. To address this, we propose a correlation-based emotion recognition algorithm (CorrNet) to recognize the valence and arousal (V-A) of each instance (fine-grained segment of signals) using only wearable, physiological signals (e.g., electrodermal activity, heart rate). CorrNet takes advantage of features both inside each instance (intra-modality features) and between different instances for the same video stimuli (correlation-based features). We first test our approach on an indoor-desktop affect dataset (CASE), and thereafter on an outdoor-mobile affect dataset (MERCA) which we collected using a smart wristband and wearable eyetracker. Results show that for subject-independent binary classification (high-low), CorrNet yields promising recognition accuracies: 76.37% and 74.03% for V-A on CASE, and 70.29% and 68.15% for V-A on MERCA. Our findings show: (1) instance segment lengths between 1–4 s result in highest recognition accuracies (2) accuracies between laboratory-grade and wearable sensors are comparable, even under low sampling rates (≤64 Hz) (3) large amounts of neutral V-A labels, an artifact of continuous affect annotation, result in varied recognition performance.

Recent research has explored the role of empathy in the context of music listening. Here, through an empathy priming paradigm, situational empathy was shown to act as a causal mechanism in inducing emotion, although the way empathy was primed had low levels of ecological validity. We therefore conducted an online experiment to explore the extent to which information about a composer’s expressive intentions when writing a piece of music would significantly affect the degree to which participants reportedly empathise with the composer and in turn influence emotional responses to expressive music. A total of 229 participants were randomly assigned to three groups. The experimental group read short texts describing the emotions felt by the composer during the process of composition. To control for the effect of text regardless of its content, one control group read texts describing the characteristics of the music they were to hear, and a second control group was not given any textual information. Participants listened to 30-second excerpts of four pieces of music, selected to express emotions from the four quadrants of the circumplex theory of emotion. Having heard each music excerpt, participants rated the valence and arousal they experienced and completed a measure of situational empathy. Results show that situational empathy in response to music is significantly associated with trait empathy. As opposed to those in the control conditions, participants in the experimental group responded with significantly higher levels of situational empathy. Receiving this text significantly moderated the effect of the expressiveness of stimuli on induced emotion, indicating that it induced empathy. We conclude that empathy can be induced during music listening through the provision of information about the specific emotions of a person relating to the music. These findings contribute to an understanding of the psychological mechanisms that underlie emotional responses to music.

The article discusses some of the research findings related to the topic of the place and function of histori-ans on social networks. The main attention is paid to identifying the role of web technologies in the con-ventional practices of creating historical knowledge creation of historical knowledge. It is emphasized that the thesis about blurring the boundaries between the professional community and users in general does not mean rejection of the recognition of the decisive role of the professional community in the production of knowledge. The ways and methods of historians' actions in social networks and their advantages over traditional methods of knowledge production are revealed.

We examined the emotional effects of (a) a rising versus a falling chromatic tone sequence in the background of audio news and (b) foreground versus background diatonic and chromatic tone sequences. In experiment one, 26 participants rated audio news messages with rising and falling chromatic background tone sequences on the valence and arousal dimensions. Cardiac activity, electrodermal activity (EDA), and facial muscle activity were also recorded continuously. In experiment two, 24 participants rated six plain tone sequences ( i.e., rising and falling chromatic, major, and minor) and six news messages with the aforementioned tone sequences mixed in the background on the valence and arousal dimensions. In experiment 1, both self-reported arousal and physiological arousal as measured by EDA were higher during the news with a rising-tone sequence compared to those with a falling-tone sequence. In experiment 2, rising-tone sequences prompted both higher arousal and pleasantness ratings. However, the responses were moderated by the type of listening task: foreground listening prompted responses related to musical connotations ( i.e., major tone sequences were rated as most pleasant and minor as most unpleasant), whereas background listening prompted responses dependent on the emotional congruence between the news messages and tone sequences ( i.e., the minor mode versions were rated as most pleasant and the major mode versions as most unpleasant). In addition, level of education-, music listening frequency-, and age-related differences in the responses were found and are discussed.

Insight Into

There is a strong increase in the use of devices that measure physiological arousal through electrodermal activity (EDA). Although there is a long tradition of studying emotions during learning, researchers have only recently started to use EDA to measure emotions in the context of education and learning. This systematic review aimed to provide insight into how EDA is currently used in these settings. The review aimed to investigate the methodological aspects of EDA measures in educational research and synthesize existing empirical evidence on the relation of physiological arousal, as measured by EDA, with learning outcomes and learning processes. The methodological results pointed to considerable variation in the usage of EDA in educational research and indicated that few implicit standards exist. Results regarding learning revealed inconsistent associations between physiological arousal and learning outcomes, which seem mainly due to underlying methodological differences. Furthermore, EDA frequently fluctuated during different stages of the learning process. Compared to this unimodal approach, multimodal designs provide the potential to better understand these fluctuations at critical moments. Overall, this review signals a clear need for explicit guidelines and standards for EDA processing in educational research in order to build a more profound understanding of the role of physiological arousal during learning.

Challenge Hypothesis

From an evolutionary perspective, questions have been raised about whether women have a psychobiological pattern similar to that of men. In humans, hormonal effects of competition and its outcome have been investigated under the biosocial status hypothesis, which proposes that, after a competition, winners would show increases in testosterone whereas losers would show reductions, and the challenge hypothesis, which emphasizes the functional role of testosterone increases in the spring to promote agonistic behavior related to territoriality and access to females. Subsequently, the coping competition model has defended the study of competition within a more general stress model, considering the psychobiological responses as part of the coping response. This chapter shows that women investigations are increasing in number in recent years and that, in competitive situations, they present coping strategies with a psychobiological response pattern that can be enlightened by the coping competition model.
