Emotional Face

When two identical objects on a screen move toward each other, coincide at the center of the screen, and then continue to move along their original trajectories to the opposite starting points, observers perceive these visual stimuli as showing one of the two possible scenarios: streaming through or bouncing off each other (stream/bounce perception). Previous research has shown that when a high-arousal face is presented along with the two moving objects, the bouncing percept was predominant, as compared with when a middle- or low-arousal face is presented. In this study, however, such a modulatory effect of the emotional face was eliminated when participants did not judge stream or bounce and the terms “bouncing/streaming” were not used in the experiments. These results suggest that the modulatory effect of emotional stimuli on the stream/bounce judgment cannot be explained solely by the emotional processing per se but, rather, can be modulated by language-based processing.

We investigated the differences in the emotional experiences of people who smoke and have damaged interoceptive awareness. Interoception is the sensation of the physiological condition of the body, and it has 2 biases: neglect and amplification of bodily feedback. We recruited 72 participants and divided them into 4 groups according to smoking status and interoceptive bias based on their scores on the Multidimensional Assessment of Interoceptive Awareness. All groups assessed their physiological and subjective arousal before and after watching video clips (positive–low arousal, positive–high arousal, negative–low arousal, negative–high arousal, neutral). The results indicated that people with amplification (vs. neglect) bias who smoked showed stronger subjective arousal to neutral stimuli. In contrast, people with amplification (vs. neglect) bias who did not smoke showed stronger subjective arousal to positive stimuli. These findings suggest that people who smoke and have an amplification bias could be more likely to misinterpret neutral emotional stimuli, leading to an increased craving for smoking.

ABSTRACTBackgroundCognitive theories associate depression with negative biases in information processing. Although negatively biased cognitions are well documented in depressed patients and to some extent in recovered patients, it remains unclear whether these abnormalities are present before the first depressive episode.MethodHigh neuroticism (N) is a well-recognized risk factor for depression. The current study therefore compared different aspects of emotional processing in 33 high-N never-depressed and 32 low-N matched volunteers. Awakening salivary cortisol, which is often elevated in severely depressed patients, was measured to explore the neurobiological substrate of neuroticism.ResultsHigh-N volunteers showed increased processing of negative and/or decreased processing of positive information in emotional categorization and memory, facial expression recognition and emotion-potentiated startle (EPS), in the absence of global memory or executive deficits. By contrast, there was no evidence for effects of neuroticism on attentional bias (as measured with the dot-probe task), over-general autobiographical memory, or awakening cortisol levels.ConclusionsThese results suggest that certain negative processing biases precede depression rather than arising as a result of depressive experience per se and as such could in part mediate the vulnerability of high-N subjects to depression. Longitudinal studies are required to confirm that such cognitive vulnerabilities predict subsequent depression in individual subjects.

Audiovisual semantic congruency during memory encoding has been shown to facilitate later recognition memory performance. However, it is still unclear whether this improvement is due to multisensory semantic congruency or just semantic congruencyper se. We investigated whether dual visual encoding facilitates recognition memory in the same way as audiovisual encoding. The participants memorized auditory or visual stimuli paired with a semantically congruent, incongruent or non-semantic stimulus in the same modality or in the other modality during encoding. Subsequent recognition memory performance was better when the stimulus was initially paired with a semantically congruent stimulus than when it was paired with a non-semantic stimulus. This congruency effect was observed with both audiovisual and dual visual stimuli. The present results indicate that not only multisensory but also unisensory semantically congruent stimuli can improve memory performance. Thus, the semantic congruency effect is not solely a multisensory phenomenon, as has been suggested previously.

Emotional Face

Twenty one adults looked at emotional (sad, happy, fearful) or neutral faces. EEG measures showed that emotional significance of face (stimulus type) modulated the amplitude of EEG, especially for theta and delta frequency band power. Also, emotional discrimination by theta was more distributed on the posterior sites of the scalp for the emotional stimuli. Thus, this frequency band variation could represent a complex set of cognitive processes whereby selective attention becomes focused on an emotional-relevant stimulus.

Social Attributions

In this study, paradigms that test whether human infants make social attributions to simple moving shapes were adapted for use with bottlenose dolphins. The dolphins observed animated displays in which a target oval would falter while moving upward, and then either a “prosocial” oval would enter and help or caress it or an “antisocial” oval would enter and hinder or hit it. In subsequent displays involving all three shapes, when the pro- and antisocial ovals moved offscreen in opposite directions, the dolphins reliably predicted—based on anticipatory head turns when the target briefly moved behind an occluder—that the target oval would follow the prosocial one. When the roles of the pro- and antisocial ovals were reversed toward a new target, the animals’ continued success suggests that such attributions may be dyad specific. Some of the dolphins also directed high arousal behaviors toward these displays, further supporting that they were socially interpreted.

Our eyes are always in search of exploring our surrounding environment. The brain controls our eyes’ activities through the nervous system. Hence, analyzing the correlation between the activities of the eyes and brain is an important area of research in vision science. This paper evaluates the coupling between the reactions of the eyes and the brain in response to different moving visual stimuli. Since both eye movements and EEG signals (as the indicator of brain activity) contain information, we employed Shannon entropy to decode the coupling between them. Ten subjects looked at four moving objects (dynamic visual stimuli) with different information contents while we recorded their EEG signals and eye movements. The results demonstrated that the changes in the information contents of eye movements and EEG signals are strongly correlated ([Formula: see text]), which indicates a strong correlation between brain and eye activities. This analysis could be extended to evaluate the correlation between the activities of other organs versus the brain.

Abstract Background: Cognitive impairments have been reported in patients with pituitary adenoma; however, there is a lack of knowledge of investigating the emotional stimuli processing in pituitary patients. Thus, we aimed to investigate whether there is emotional processing dysfunction in pituitary patients by recording and analyzing the late positive potential (LPP) elicited by affective stimuli.Methods: Evaluation of emotional stimuli processing by LPP Event related potentials (ERPs) was carried out through central- parietal electrode sites (C3, Cz, C4, P3, Pz, P4) on the head of the patients and healthy controls (HCs).Results: In the negative stimuli, the amplitude of LPP was 2.435 ± 0.419μV for HCs and 0.656 ± 0.427μV for patient group respectively ( p = 0.005). In the positive stimuli, the elicited electric potential 1.450 ± 0.316μV for HCs and 0.495 ± 0.322μV for patient group respectively ( p = 0.040). Moreover, the most obvious difference of LPP amplitude between the two groups existed in the right parietal region. On the right hemisphere (at the P4 site), the elicited electric potential was 1.993 ± 0.299μV for HCs and 0.269 ± 0.305μV for patient group respectively( p = 0.001).Conclusion: There are functional dysfunction of emotional stimuli processing in pituitary adenoma patients. Our research provides the electrophysiological evidence for the presence of cognitive dysfunction which need to be intervened in the pituitary adenoma patients.

Duration Estimation

Abstract Emotional stimuli like emotional faces have been frequently shown to be temporally overestimated compared to neutral ones. This effect has been commonly explained by induced arousal caused by emotional processing leading to the acceleration of an inner-clock-like pacemaker. However, there are some studies reporting contradictory effects and others point to relevant moderating variables. Given this controversy, we aimed at investigating the processes underlying the temporal overestimation of emotional faces by combining behavioral and electrophysiological correlates in a temporal bisection task. We assessed duration estimation of angry and neutral faces using anchor durations of 400 ms and 1600 ms while recording event-related potentials. Subjective ratings and the early posterior negativity confirmed encoding and processing of stimuli’s emotionality. However, temporal ratings did not differ between angry and neutral faces. In line with this behavioral result, the Contingent Negative Variation (CNV), an electrophysiological index of temporal accumulation, was not modulated by the faces’ emotionality. Duration estimates, i.e., short or long responses toward stimuli of ambiguous durations of 1000 ms, were nevertheless associated with a differential CNV amplitude. Interestingly, CNV modulation was already observed at 600–700 ms after stimulus onset, i.e., long before stimulus offset. The results are discussed in light of the information-processing model of time perception as well as regarding possible factors of the experimental setup moderating temporal overestimation of emotional stimuli. In sum, combining behavioral and electrophysiological measures seems promising to more clearly understand the complex processes leading to the illusion of temporal lengthening of emotional faces.

Suggestions can cause some individuals to miss or disregard existing visual stimuli, but can they infuse sensory input with nonexistent information? Although several prominent theories of hypnotic suggestion propose that mental imagery can change our perceptual experience, data to support this stance remain sparse. The present study addressed this lacuna, showing how suggesting the presence of physically absent, yet critical, visual information transforms an otherwise difficult task into an easy one. Here, we show how adult participants who are highly susceptible to hypnotic suggestion successfully hallucinated visual occluders on top of moving objects. Our findings support the idea that, at least in some people, suggestions can add perceptual information to sensory input. This observation adds meaningful weight to theoretical, clinical, and applied aspects of the brain and psychological sciences.
