The moderating role of consumer entitlement on the relationship of value with customer satisfaction

This research provides an extension of Oliver's (1980) expectancy disconfirmation model of satisfaction by examining the moderating role of consumer entitlement in the relationships between service quality and perceived value with customer satisfaction. Using a sample of season ticket holders of the National Hockey League franchise in the southeastern USA (n = 234), we found that consumer entitlement moderates the relationship of value with satisfaction, such that the impact of consumer‐perceived service value on satisfaction is mitigated for highly entitled consumers. That is, the positive value–satisfaction relationship is stronger for individuals low in consumer entitlement. This finding suggests that highly entitled consumers' satisfaction judgments are dominated by expectations, while less entitled consumers rely more on disconfirmation assessments. Strengths, limitations, suggestions for future research, and practical implications are offered. Copyright © 2015 John Wiley & Sons, Ltd.     

Maternal cradling bias in baboons: The first environmental factor affecting early infant handedness development?

The most emblematic behavioral manifestation of human brain asymmetries is handedness. While the precise mechanisms behind the development of handedness are still widely debated, empirical evidences highlight that besides genetic factors, environmental factors may play a crucial role. As one of these factors, maternal cradling behavior may play a key role in the emergence of early handedness in the offspring. In the present study we followed 41 Papio anubis infants living in social groups with their mother for which direction (e.g., left- or right-arm) and degree of maternal cradling-side bias were available from a previous published study. We assessed hand preferences for an unimanual grasping task at three developmental stages: (A) 0–4, (B) 4—6, and (C) 9–10 months of age. We found that individual hand preferences for grasping exist as soon as the first months of age, with a population-level left-handedness predominance, being stable until 6 months; to wit the period during which juveniles are mainly carried by their mothers. More importantly, this early postnatal handedness is positively correlated with maternal cradling lateralization. Interestingly, hand preferences assessed later in the development, once juveniles are no longer carried (i.e., from 9 to 10 months of age), are less dependent from the maternal cradling bias and less consistent with the earlier developmental stages, especially in infants initially cradled on the right maternal side. Our findings suggest that the ontogenetic dynamics of the infant's hand preference and its changes might ultimately rely on the degree of infant dependence from the mother across development.     

Contrast of hemispheric lateralization for oro-facial movements between learned attention-getting sounds and species-typical vocalizations in chimpanzees: Extension in a second colony

Studies involving oro-facial asymmetries in nonhuman primates have largely demonstrated a right hemispheric dominance for communicative signals and conveyance of emotional information. A recent study on chimpanzee reported the first evidence of significant left-hemispheric dominance when using attention-getting sounds and rightward bias for species-typical vocalizations (Losin, Russell, Freeman, Meguerditchian, Hopkins & Fitch, 2008). The current study sought to extend the findings from Losin et al. (2008) with additional oro-facial assessment in a new colony of chimpanzees. When combining the two populations, the results indicated a consistent leftward bias for attention-getting sounds and a right lateralization for species-typical vocalizations. Collectively, the results suggest that both voluntary-controlled oro-facial and gestural communication might share the same left-hemispheric specialization and might have coevolved into a single integrated system present in a common hominid ancestor.     

LE CARACTÈRE TOPOLOGIQUE DES PREMIÈRES REPRÈSENTATIONS SPATIALES DE l'ENFANT

The topological nature of the child's early spatial representations. Piaget's hypotheses revisited. — Three experiments bearing on Piaget's hypotheses on the topological nature of the child's early concepts of space are reported. The results of the first experiment, replicating Piaget's stereognostic technique on a larger scale, were shown to confirm the earliness of topological discriminations, but it was found also that some simple Euclidian discriminations (curvilinear vs rectilinear, indented vs non-indented forms) were not more difficult. The second experiment has shown that the child relied rather on topological than on simple Euclidian attributes when both types of attributes were presented in a conflictual situation; otherwise, the simple Euclidian discriminations were easier. In a third experiment, using a drawing technique along with visual exploration, topological discriminations proved easier than Euclidian discriminations in one instance only (open-closed vs curvilinear-rectilinear forms). It is suggested in conclusion that the child's early discriminations are not based on topology as such, but on certain geometrical properties which are fundamental to topology itself.     

Psychoanalytic psychodrama in France and group elaboration of counter‐transference: Therapeutic operators in play therapy

In France, psychoanalytic psychodrama is mainly envisioned in its individual form – that is, a single patient working with a group of therapists. Its originality consists in bringing together several clinicians within a clinical experience that is shared as a group. This experience is fundamentally different from traditional individual therapies, psychotherapies or group co‐led therapies. Its configuration may be confusing or overwhelming due to the large number of co‐therapists involved in the setting. However, thanks to group elaboration based on the transferential‐countertransferential dynamics induced by the treated patient, this potential ‘cacophony’ can lead to fruitful psychic development embedded in play. This is tied to the co‐therapists' positioning in the transitional space shared with the patient as well as to the patient's subjective appropriation of their initiatives. By reflecting on clinical material taken from actual sessions as well as from the exchanges and elaborations occurring at their margins, this article shows how psychodrama and group come to metabolize the transferential elements, shaping the engagement of participants in the context of improvised play.     

Temporal compression in episodic memory for real-life events

Remembering an event typically takes less time than experiencing it, suggesting that episodic memory represents past experience in a temporally compressed way. Little is known, however, about how the continuous flow of real-life events is summarised in memory. Here we investigated the nature and determinants of temporal compression by directly comparing memory contents with the objective timing of events as measured by a wearable camera. We found that episodic memories consist of a succession of moments of prior experience that represent events with varying compression rates, such that the density of retrieved information is modulated by goal processing and perceptual changes. Furthermore, the results showed that temporal compression rates remain relatively stable over one week and increase after a one-month delay, particularly for goal-related events. These data shed new light on temporal compression in episodic memory and suggest that compression rates are adaptively modulated to maintain current goal-relevant information.     

Toward an exploration of feeling of strangeness in schizophrenia: perspectives on acousmatic and everyday listening

The aim of this study was to investigate abnormal perceptual experiences in schizophrenia, in particular the feeling of strangeness, which is commonly found in patients' self-reports. The experimental design included auditory complex stimuli within 2 theoretical frameworks based on "sensory gating deficit" and "aberrant salience," inspired from conventional perceptual scales. A specific sound corpus was designed with environmental (meaningful) and abstract (meaningless) sounds. The authors compared sound evaluations on 3 perceptual dimensions (bizarre, familiar, and invasive) and 2 emotional dimensions (frightening and reassuring) between 20 patients with schizophrenia (SCZ) and 20 control participants (CTL). The perceptual judgment was rated on independent linear scales for each sound. In addition, the conditioning-testing P50 paradigm was conducted on 10 SCZ and 10 CTL. Both behavioral and electrophysiological data confirmed the authors' expectations according to the 2 previous theoretical frameworks and showed that abnormal perceptual experiences in SCZ consisted of perceiving meaningful sounds in a distorted manner and as flooding/inundating but also in perceiving meaningless sounds as things that become meaningful by assigning them some significance. In addition, the use of independent scales to each perceptual dimension highlighted an unexpected ambivalence on familiarity and bizarreness in SCZ compatible with the explanation of semantic process impairment. The authors further suggested that this ambivalence might be due to a conflicting coactivation of 2 types of listening, that is, every day and musical (or acousmatic) listening.
