“…In a task of judging facial expressions and pictures of infants, Proverbio, Brignone, Matarazzo, Del Zotto, and Zani (2006) found an asymmetrical activation of the visual cortex (early face-sensitive P1 and N1 components) in men (with right-hemisphere predominance), and bilateral activity in women. Gasbarri et al (2007) observed a sexrelated hemispheric lateralization of electrical potentials evoked by arousing negative pictures. Negative pictures elicited more robust P300 effects in the left hemisphere in women and in the right hemisphere in men.…”

A review on sex differences in processing emotional signals

a b s t r a c tInterest in sex-related differences in psychological functioning has again come to the foreground with new findings about their possible functional basis in the brain. Sex differences may be one way how evolution has capitalized on the capacity of homologous brain regions to process social information between men and women differently. This paper focuses specifically on the effects of emotional valence, sex of the observed and sex of the observer on regional brain activations. We also discuss the effects of and interactions between environment, hormones, genes and structural differences of the brain in the context of differential brain activity patterns between men and women following exposure to seen expressions of emotion and in this context we outline a number of methodological considerations for future research. Importantly, results show that although women are better at recognizing emotions and express themselves more easily, men show greater responses to threatening cues (dominant, violent or aggressive) and this may reflect different behavioral response tendencies between men and women as well as evolutionary effects. We conclude that sex differences must not be ignored in affective research and more specifically in affective neuroscience.

“…Some studies were conducted on a single gender, such as those investigating women's emotions during motherhood and parental status [133,134,164] and a study of men [215]. Some studies targeted a specific type of subject, such as healthy people or patients, to investigate and observe the differences in emotions between two different groups, such as control and healthy groups in [76,107,135], groups of women and men in [46,97,177], young adults versus older adults in [87,216], or children versus adults in [126,143].…”

Review and Classification of Emotion Recognition Based on EEG Brain-Computer Interface System Research: A Systematic Review

et al. 2017

View full text Add to dashboard Cite

Abstract:Recent developments and studies in brain-computer interface (BCI) technologies have facilitated emotion detection and classification. Many BCI studies have sought to investigate, detect, and recognize participants' emotional affective states. The applied domains for these studies are varied, and include such fields as communication, education, entertainment, and medicine. To understand trends in electroencephalography (EEG)-based emotion recognition system research and to provide practitioners and researchers with insights into and future directions for emotion recognition systems, this study set out to review published articles on emotion detection, recognition, and classification. The study also reviews current and future trends and discusses how these trends may impact researchers and practitioners alike. We reviewed 285 articles, of which 160 were refereed journal articles that were published since the inception of affective computing research. The articles were classified based on a scheme consisting of two categories: research orientation and domains/applications. Our results show considerable growth of EEG-based emotion detection journal publications. This growth reflects an increased research interest in EEG-based emotion detection as a salient and legitimate research area. Such factors as the proliferation of wireless EEG devices, advances in computational intelligence techniques, and machine learning spurred this growth.

“…Similarly, during the processing of negatively valenced words, women show increased activity relative to men in the right putamen, right superior temporal gyrus, and left supramarginal gyrus (Hofer et al 2007). ERP studies have also shown differing response patterns to emotional material between men and women (Orozco and Ehlers 1998;Gasbarri et al 2007). Furthermore, sex differences have been identified in activity during encoding which predicts subsequent memory performance, particularly in the amygdala (Canli et al 2002;Cahill et al 2004).…”

In essentially every domain of neuroscience, the generally implicit assumption that few, if any, meaningful differences exist between male and female brain function is being challenged. Here we address how this development is influencing studies of the neurobiology of learning and memory. While it has been commonly held that males show an advantage on spatial tasks, and females on verbal tasks, there is increasing evidence that sex differences are more widespread than previously supposed. Differing performance between the sexes have been observed on a number of common learning tasks in both the human and animal literature, many neither purely spatial nor verbal. We review sex differences reported in various areas to date, while attempting to identify common features of sexually dimorphic tasks, and to place these differences in a neurobiological context. This discussion focuses on studies of four classes of memory tasks for which sex differences have been frequently reported: spatial, verbal, autobiographical, and emotional memory. We conclude that the female verbal advantage extends into numerous tasks, including tests of spatial and autobiographical abilities, but that a small but significant advantage may exist for general episodic memory. We further suggest that for some tasks, stress evokes sex differences, which are not normally observed, and that these differences are mediated largely by interactions between stress and sex hormones.Sex influences on brain function are ubiquitous. Differences between the sexes have been documented at every level of neuroscience, from single neurons in cell culture to systems level processes as measured by neuroimaging. In some cases, consideration of sex may significantly alter, even reverse, conclusions about brain function drawn from the study of one sex alone (Cahill 2006). In some fields, such as the study of drug addiction, the evidence for sex differences is so strong that consideration of sex as a factor is becoming the norm, rather than the exception (Wetherington 2007).The claim that these neurobiological sex differences extend to the behavioral level has typically been more controversial. A recent review of the literature on this topic warns against the ''costs of overinflated claims of gender differences.'' The review holds that overall ''males and females are alike on most-but not all-psychological variables'' (Hyde 2005), but notes exceptions where sex does have an effect, including sexual and aggressive behaviors. Still, given how broadly sex differences are distributed on the neural level, it seems unlikely that their behavioral effects would be restricted solely to these domains.One area of behavior not considered in Hyde's review is the influence of sex on learning and memory. It is becoming increasingly clear, however, that an understanding of the neurobiological and cognitive consequences of sex is relevant across this field. In the review that follows, behavioral evidence indicating differences between men and women from numerous memory tasks will be co...
