Positive And Negative Valence

Abstract The response of the insular cortex (IC) and amygdala to stimuli of positive and negative valence were found to be altered in patients with anxiety disorders. However, the coding properties of neurons controlling anxiety and valence remain unknown. Combining photometry recordings and chemogenetics in mice, we uncover the anxiogenic control of projection neurons in the anterior IC (aIC), independently of their projection target. Using viral tracing and ex vivo electrophysiology, we characterize the monosynaptic aIC to the basolateral amygdala (BLA) connection, and employed projection-specific optogenetics, to reveal anxiogenic properties of aIC-BLA neurons in anxiety-related behaviors. Finally, using photometry recordings, we identified that aIC-BLA neurons are active in anxiogenic spaces, and in response to aversive stimuli. Together, these findings show that negative valence, as well as anxiety-related information and behaviors, are encoded by aICBLA glutamatergic neurons, providing a starting point to understand how alterations of this pathway contribute to psychiatric disorders.

Symmetry and contour take part in shaping visual preference. However, less is known about their combined contribution to preference. We examined the hedonic tone and preference triggered by the interaction of symmetry and contour. Symmetric/curved, symmetric/sharp-angled, asymmetric/curved, and asymmetric/sharp-angled stimuli were presented in an implicit and explicit task. The implicit task consisted of an affective stimulus-response compatibility task where participants matched the stimuli with positive and negative valence response cues. The explicit task recorded liking ratings from the same stimuli. We used instructed mindset to induce participants to focus on symmetry or contour in different parts of the experimental session. We found an implicit compatibility of symmetry and curvature with positive hedonic tone. Explicit results showed preference for symmetry and curvature. In both tasks, symmetry and curvature showed a cumulative interaction, with a larger contribution of symmetry to the overall effect. While symmetric and asymmetric stimuli contributed to the implicit positive valence of symmetry, the effect of curvature was mainly caused by inclination toward curved contours rather than rejection of sharp-angled contours. We did not find any correlation between implicit and explicit measures, suggesting that they may involve different cognitive processing.

Affective Information

Although studies have investigated the influence of the emotionality of primes on the cross-modal affective priming effect, it is unclear whether this effect is due to the contribution of the arousal or the valence of primes. We explored how the valence and arousal of primes influenced the cross-modal affective priming effect. In Experiment 1 we manipulated the valence of primes (positive and negative) that were matched by arousal. In Experiments 2 and 3 we manipulated the arousal of primes under the conditions of positive and negative valence, respectively. Affective words were used as auditory primes and affective faces were used as visual targets in a priming task. The results suggest that the valence of primes modulated the cross-modal affective priming effect but that the arousal of primes did not influence the priming effect. Only when the priming stimuli were positive did the cross-modal affective priming effect occur, but negative primes did not produce a priming effect. In addition, for positive but not negative primes, the arousal of primes facilitated the processing of subsequent targets. Our findings have great significance for understanding the interaction of different modal affective information.

The Impact

Purpose It has now become a normal part of the consumption journey for consumers to share their positive and negative service encounters with firms on microblogs such as Twitter. There is, however, a limited amount of research on service encounter microblog word of mouth (SEMWOM) and its impact on firm reputation from a receiver’s perspective. This study aims to understand the comparative effects of positive and negative valence SEMWOM on receivers’ perceptions of firms’ reputations and the factors that are particularly salient to receivers’ perceptions of firm reputation upon exposure to SEMWOM. Design/methodology/approach An experiment exposed 372 Twitter users to positive and negative valence SEMWOM. To determine whether changes in perception of firm reputation occurred on exposure to both positive and negative valence SEMWOM, participants’ perceptions of a range of US airlines were measured before and after exposure to the SEMWOM. To confirm the factors that influence the perception of reputation on such exposure, six structural equation models were created to determine the comparative effects of positive and negative valence SEMWOM among three electronic WOM media as follows: video, photo and text. Findings Both positive and negative valence SEMWOM affect receivers’ perceptions of airlines’ reputations on exposure. Furthermore, the factors that influence perceptions of reputation on exposure to SEMWOM vary depending on valence and type of media contained in a tweet. Originality/value Although consumers now routinely share their positive and negative service encounters with brands on microblogs, scant research has examined receivers of positive and negative valence SEMWOM, important actors in the microblog domain. This study addresses this research gap by empirically investigating the impact of both positive and negative valence SEMWOM on receivers’ perceptions of firm reputation upon exposure to it.

AbstractThis study explores how young children infer nuances in epistemic modality through prosody. A forced-choice task was used, testing children's (ages three to seven) comprehension of the might/will distinction (modal condition) as well their ability to modulate the strength of might through two prosodic tunes (prosody condition). Positive and negative valence conditions were included. Younger children were shown to start off performing above chance for the modal condition, and at around chance for the prosody condition, but after age four performance on the prosody condition quickly improved. For both modal verbs and prosody, children performed significantly better when valence was positive. By age seven, children performed at ceiling for all conditions. Qualitative analysis of children's justifications for prosody responses showed metalinguistic awareness of prosodic meaning as early as age four, with the ability to relate prosody to epistemic modal meaning becoming quite common by age seven.
