Spontaneous emotion regulation to positive and negative stimuli

The ability to regulate one’s emotions is an integral part of human social behavior. One antecedent emotion regulation strategy, known as reappraisal, is characterized by cognitively evaluating an emotional stimulus to alter its emotional impact and one response-focused strategy, suppression, is aimed at reducing behavioral output. People are capable of using these specific emotion regulation strategies when instructed to do so; however, it is equally important to investigate natural and self-selected strategy use. This study was designed to determine to what extent people spontaneously regulate their emotions and the emotion regulation strategies they choose to achieve their regulatory goals. Participants were given no instructions to regulate their emotions before they were shown a negative and a positive film clip, but were instead asked afterwards about the specific strategies that they had used. Participants reported regulating their emotions more to the negative film than to the positive film. Reappraisal was more frequently selected as an emotion regulation strategy than suppression. As expected, participants with high baseline respiratory sinus arrhythmia (RSA) adopted reappraisal strategies more than those with low RSA but, surprisingly, RSA was not associated with facial expressivity. Suggestions for future research in this relatively young field of spontaneous emotion regulation are offered.     

Is there "feedback" during visual imagery? Evidence from a specificity of practice paradigm.

The specificity of practice hypothesis predicts the development of a sensorimotor representation specific to the afferent feedback available during skill acquisition (Proteau, 1992; Proteau, Marteniuk, Girouard, & Dugas, 1987). In the present investigation, we used the specificity of practice hypothesis to test whether skill acquisition through visual imagery would lead to the development of a sensory-specific movement representation similar to one resulting from actual practice. To accomplish this objective, participants practiced walking a 12-m linear path in one of three practice conditions, full-vision (FV), no-vision (NV), or visual imagery (VI), for either 10 or 100 trials. Knowledge of spatial and/or temporal results (KR) was provided to participants following each trial during this phase. Following acquisition, participants completed 10 NV trials without KR. An analysis of root-mean-squared-error (RMSE) indicated NV participants were more accurate than both FV and VI participants in the transfer condition. We believe the equivalence in transfer RMSE between FV and VI suggests that there are similarities between the movement representations attained by FV and VI practice.     

How the Defendant's Emotion Level Affects Mock Jurors' Decisions When Presentation Mode and Evidence Strength Are Varied1

Two experiments (N= 443) were conducted to investigate the effects of a defendant's emotion level during testimony on mock jurors' decisions. In Experiment 1, the defendant's level of emotion (low, moderate, high) and mode of presentation (audio, video) were varied. The defendant displaying a low level, as opposed to a higher level of emotion was perceived as more guilty and less credible. In Experiment 2, using only the video mode, emotion level and evidence strength (strong, weak) were varied. Defendant emotion level tended to affect jurors' decisions only when the evidence against the defendant was weak (i.e., a stronger display of emotion was associated with a lower proportion of guilty verdicts, shorter sentence assignments, and perceptions of a more honest defendant). Path analyses for both experiments indicate that the effects of emotion on perceived guilt level are mediated by perceptions of the defendant (e.g., the defendant's level of honesty). Implications of using defendant emotion level for determining guilt are discussed.     

Unbinding Lazarus

This article proposes a Wesleyan theological rationale and practical recommendations for revitalized theological education, particularly in university‐based schools of theology. The approach integrates a rigorous life‐long learning system that includes curricular and co‐curricular programmes and contextual learning, with a strong foundation in missional ecclesiology and contemplative, kenotic spirituality. It takes seriously the formational needs of practitioners of emergence Christianity such as the new monasticism, missional communities, and the like, so as to reflect upon best practices of theological education to resource leaders of the inherited church while offering recommendations for empowering leaders of ancient/future expressions of church.     

Time course analysis of closed- and open-loop grasping of the Müller-Lyer illusion

The authors investigated whether the early or later stages of closed-loop (CL) and open-loop (OL) grasping movements were differentially influenced by the Müller-Lyer (ML) illusion. Participants (N = 21) reached out and grasped small (5 cm) and large (7 cm) objects embedded within fins-in and fins-out ML configurations. Grasping time (GT) was normalized, and absolute grip aperture (GA) as well as scaled illusion effects were computed at 20%, 40%, 60%, and 80% of GT. The results indicated that CL trials were refractory to the illusory array (i.e., from 20% to 80% of GT), whereas OL trials were influenced by the ML figure during that same time. Those findings suggest that CL trials were supported by unitary and metrical visual information, whereas OL trials were entirely supported by perception-based visual information.     

Manual asymmetries in bimanual reaching: the influence of spatial compatibility and visuospatial attention

The goal of the present investigation was to explore the possible expression of hemispheric-specific processing during the planning and execution of a bimanual reaching task. Participants (N = 9) completed 80 bimanual reaching movements (requiring simultaneous, bilateral production of arm movements) to peripherally presented targets while selectively attending to either their left or right hand. Further, targets were presented in spatially compatible (ipsilateral to the aiming limb) and incompatible (contralateral to the aiming limb) response contexts. It was found that the left hand exhibited temporal superiority over the right hand in the response planning phase of bimanual reaching, indicating a left hand/right hemisphere advantage in the preparation of a bimanual response. During response execution, and consistent with the view that interhemispheric processing time (Barthelemy & Boulinguez, 2002) or biomechanical constraints (Carey, Hargreaves, & Goodale, 1996) generate temporal delays, longer movement times were observed in response to spatially incompatible target positions. However, no hemisphere-specific benefit was demonstrated for response execution. Based on these findings, we propose lateralized processing is present at the time of response planning (i.e., left hand/right hemisphere processing advantage); however, lateralized specialization appears to be annulled during dynamic execution of a bimanual reaching task.     

Action control: independent effects of memory and monocular viewing on reaching accuracy

Evidence suggests that perceptual networks in the ventral visual pathway are necessary for action control when targets are viewed with only one eye, or when the target must be stored in memory. We tested whether memory-linked (i.e., open-loop versus memory-guided actions) and monocular-linked effects (i.e., binocular versus monocular actions) on action arise from a common mechanism as suggested by evidence from neuropsychology and psychophysics. Participants viewed targets with either one eye or two (vision: monocular versus binocular) and then reached to touch targets in open-loop and memory-guided conditions (condition: open-loop versus 0, 500, 1000, and 1500 ms delays). Results showed that memory-linked and monocular-linked increases in radial and variable movement error were additive (i.e., main effects of vision and condition, but no interaction). This suggests that the two effects on visuomotor control arise from separate mechanisms, in contrast to evidence from psychophysics and neuropsychology suggesting a common underlying mechanism.     

Idea habitats: how the prevalence of environmental cues influences the success of ideas

We investigate 1 factor that influences the success of ideas or cultural representations by proposing that they have a habitat, that is, a set of environmental cues that encourages people to recall and transmit them. We test 2 hypotheses: (a) fluctuation: the success of an idea will vary over time with fluctuations in its habitat, and (b) competition: ideas with more prevalent habitats will be more successful. Four studies use subject ratings and data from newspapers to provide correlational support for our 2 hypotheses, with a negative factoid, positive rumor, catchphrases, and variants of a proverb. Three additional experimental studies manipulate the topic of actual conversations and find empirical support for our theory, with catchphrases, proverbs, and slang. The discussion examines how habitat prevalence applies to a more extensive class of ideas and suggests how habitats may influence the process by which ideas evolve.     

Resting RSA is associated with natural and self-regulated responses to negative emotional stimuli

Resting respiratory sinus arrhythmia (RSA) was assessed among 111 adult participants. These individuals were then asked to watch a positive or negative affective film in either a natural manner or while exaggerating their facial response. Facial reactions to the film were video-recorded and subsequently rated in terms of facial affect. Participants also self-reported the valence of their emotional experience. Results from regression analyses revealed that persons with low resting RSA behaviorally evidenced a more negative facial response to the negative film under natural-watch conditions. Low RSA individuals were also less able to modulate (i.e., amplify) their facial response to the negative film. In terms of self-report measures, persons in the exaggerate condition reported more positive affect to the positive film than did those in the natural-watch condition. Results suggest that cardiac vagal control is inversely associated with negative facial expression but positively associated with facial regulation ability to negative stimuli.
