Happy,sad, scary and peaceful musical excerpts for research on emotions

Three experiments were conducted in order to validate 56 musical excerpts that conveyed four intended emotions (happiness, sadness, threat and peacefulness). In Experiment 1, the musical clips were rated in terms of how clearly the intended emotion was portrayed, and for valence and arousal. In Experiment 2, a gating paradigm was used to evaluate the course for emotion recognition. In Experiment 3, a dissimilarity judgement task and multidimensional scaling analysis were used to probe emotional content with no emotional labels. The results showed that emotions are easily recognised and discriminated on the basis of valence and arousal and with relative immediacy. Happy and sad excerpts were identified after the presentation of fewer than three musical events. With no labelling, emotion discrimination remained highly accurate and could be mapped on energetic and tense dimensions. The present study provides suitable musical material for research on emotions.Keywords.     

Only your eyes tell me what you like: Exploring the liking effect induced by other's gaze

Our preferences are sensitive to social influences. For instance, we like more the objects that are looked-at by others than non-looked-at objects. Here, we explored this liking effect, using a modified paradigm of attention cueing by gaze. First, we investigated if the liking effect induced by gaze relied on motoric representations of the target object by testing if the liking effect could be observed for non-manipulable (alphanumeric characters) as well as for manipulable items (common tools). We found a significant liking effect for the alphanumeric items. Second, we tested if another type of powerful social cue could also induce a liking effect. We used an equivalent paradigm but with pointing hands instead of gaze cues. Pointing hands elicited a robust attention-orienting effect, but they did not induce any significant liking effect. This study extends previous findings and reinforces the view of eye gaze as a special cue in human interactions.     

Landmark Frames of Reference in Interactive Route Description Tasks

The current study investigated the use of frames of reference in an asymmetrical spatial dialogue task. Participants navigated through a real environment by following instructions provided by other participants guiding them over the phone. The dialogues were transcribed and analysed to locate the introduction of landmarks. We examined which frames of reference were used to introduce these landmarks and how far their use was determined by each participant's role within the dyads (i.e. guide vs. guided person). Results revealed that both partners contributed to the dialogue by introducing landmarks. However, the guides introduced more landmarks than the guided persons and were also more likely to use perspective taking when doing so. These results are discussed in the light of perspective taking and collaboration in dialogue. Copyright © 2013 John Wiley & Sons, Ltd.     

Killing the dead: evolution of melancholic identifications underlying suicide attempts in adolescence

Psychic processes underlying suicidal behaviours during adolescence and their evolution are explored. A longitudinal study was conducted of thirty adolescent patients hospitalised following a suicide attempt. Clinical interviews were used combined with the Rorschach Test and the Thematic Apperception Test (TAT) a few days after the suicide attempt and one year later. Results initially showed common forms of psychic adjustment: melancholic identifications were linked to an excessive dependence on objects. One year later, these forms of psychic adjustment changed: for many adolescents, the melancholic identifications shifted and self-image improved. The emergence of representations of murder fantasies immediately after the suicidal behaviour allowed a possible transformation of violence into symbolisation. A case study illustrates these psychic changes.     

Associations of general religiousness and specific religious beliefs with coping appraisals in response to Hurricanes Katrina and Rita

An emerging scientific literature is investigating the construct of “compassionate love,” love that is “centered on the good of the other,” a construct empirically linked to physical and mental health. We evaluated effects of an 8-week, 16-hour programme for physicians, nurses, chaplains, and other health professionals, using nonsectarian, spiritually based, self-management tools. Participants were randomised to intervention (n = 30) or wait-list (n = 31). Pretest, post-test, 8- and 19-week follow-up data were gathered on six measures of prosocial qualities. Favorable treatment effects (p<0.05) were found for compassionate love (d = 0.49), altruistic actions (d = 0.33), perspective-taking (d = 0.42), and forgiveness (d = 0.61). Treatment adherence fully mediated effects on compassionate love. Furthermore, stress reduction mediated treatment effects on compassionate love, perspective-taking, and forgiveness; each also mediated gains in caregiving self-efficacy. This encouraging evidence suggests that nonlaboratory psychospiritual interventions can boost compassionate love to benefit the recipients and the larger society.     

A PET meta‐analysis of object and spatial mental imagery

Neuroimaging studies have described the functional neuroanatomy of mental imagery. Taken separately, specific studies vary in the nature of the task used and are limited by statistical power and sensitivity. We took advantage of a multistudy PET database of 54 subjects acquired in our laboratory to reveal the neural bases of spatial versus object mental imagery tasks. Our first goal was to evaluate to what extent the activated foci elicited by both object and spatial studies overlap. A second aim was to compare activations elicited by spatial imagery tasks to those elicited by object imagery tasks. We also explored applying regression analyses to the relationships between the scores on the Mental Rotations Test (MRT) and changes in regional cerebral blood flow (rCBF) during spatial and object imagery tasks. This meta‐analysis yielded the following observations: (1) both spatial and object imagery tasks shared a common neural network composed of occipitotemporal (ventral pathway) and occipitoparietal (dorsal pathway) regions and also by a set of frontal regions (related to memory); (2) the superior parietal cortex was more strongly implicated during spatial imagery; (3) object imagery specifically engaged the anterior part of the ventral pathway, including the fusiform, parahippocampal, and hippocampal gyrus; (4) object imagery activated the early visual cortex, whereas spatial imagery induced a deactivation of the early visual cortex; (5) blood flow values in some of the regions noted above were positively correlated with scores on the MRT: the higher the subjects performed on the MRT, the more pronounced the rCBF was in these regions. These results may reconcile some of the apparent discrepancies among previous studies concerning the activation of early visual cortex in mental imagery. They also contribute to a better knowledge of the neural bases of object and spatial mental imagery.     

Grand Unified Theories of the Brain Need Better Understanding of Behavior: The Two-Tiered Emergence of Function

Abstract

Over the last few decades, neuroscience and various associated disciples have expanded enormously in terms of output, tools, methods, concepts, and large-scale projects. In spite of these developments, the principles underlying brain function and behavior are yet only partially understood. We claim that brain functioning requires the elucidation of the rules associated with all possible task realizations, rather than targeting the activity underlying a specific realization. A first step in that direction was taken by approaches focusing on dynamical structures underlying task performances, as exemplified by coordination dynamics. Its theoretical foundation owes much to Haken’s synergetics, which provides a formalism through which the degrees of freedom associated with high-dimensional systems may be effectively reduced to one or a few functional variables in the vicinity of phase transitions. The recent theoretical development of structured flows on manifolds (SFM) allows the employment to a potentially broader range of applications. Here we expand the SFM framework and propose that the emergent two-tiered fast–slow dynamics may be a basic mathematical organization underlying the architecture of brain and behavior dynamics. Finally, along a few examples, we illustrate how this framework allows for the incorporation of notions cardinal to ecological psychology.     

Self‐Monitoring and Job Performance: The moderating role of tenure

Previous research on the relationship between self‐monitoring and job performance has neglected the role of tenure even though both theory and preliminary evidences suggest that job incumbents' tenure should be a strong moderator. The current study investigates the role of organizational tenure on the relationship between self‐monitoring and job performance (number of new contracts sold) in a sample of sales insurance agents. Consistent with expectations, tenure moderates the relationship between self‐monitoring and job performance, i.e., self‐monitoring is positively correlated with job performance for job incumbents with less tenure but not for those with more tenure. We propose that the relationship between self‐monitoring and job performance depends on the job incumbents' ability and opportunity to control the cues available to those who interact with and/or appraise the performance of the job incumbent.
