SHALL WE DANCE? MUSIC AS A PORT OF ENTRANCE TO MATERNAL–INFANT INTERSUBJECTIVITY IN A CONTEXT OF POSTNATAL DEPRESSION

The present study introduces the concept of a mother–infant group therapy that makes use of music, singing, and moving to establish maternal–infant intersubjectivity. It was conducted in a residential mother–baby unit for mothers with postnatal depression and their infants over a 5‐week period. Maternal–infant intersubjectivity of four dyads in relation to the group dynamics were microanalyzed for Sessions 1 and 5. We made within‐session (i.e., beginning–middle–end) and between‐session (Session 1 vs. Session 5) comparisons for the number of intersubjectivity moments (ISMs), total time of intersubjectivity (IST), and the mean duration of ISMs on a dyadic (i.e., own mother/infant involved) and a nondyadic level (i.e., own mother/infant not involved). In addition, three ISM levels (degree of group contribution) were distinguished. The results indicated a significant increase of ISMs/IST from Session 1 to Session 5. Within‐session analyses showed that ISMs/IST significantly decreased through Session 1 and remained stable throughout Session 5. Intersubjectivity occurred mainly on ISM Level 1 during Session 1 and on ISM Level 3 during Session 5, suggesting increased dyadic autonomy and self‐efficacy. The results are discussed in relation to the musical characteristics of mother–infant dyads, music improvisation techniques, group processes, and intersubjective development.     

Reinforcement as a mediator of the perception of humans by horses (Equus caballus)

A central question in the interspecific human/animal relationship is how domestic animals perceive humans as a significant element of their environment. In this study, we tested the hypothesis that the use of positive or negative reinforcement in horse training may have consequences on the animals’ perception of humans, as a positive, negative or neutral element. Two groups of ponies were trained to walk backwards in response to a vocal order using either positive or negative reinforcement. Heart rate monitors and behavioural observations were used to assess the animals’ perception of humans on the short (just after training) and long (5 months later) terms. The results showed that the type of reinforcement had a major effect on the subsequent animals’ perception of familiar and unfamiliar humans. Negative reinforcement was rapidly associated with an increased emotional state, as revealed by heart rate measurements and behavioural observations (head movements and ears laid back position). Its use led the ponies to seek less contact with humans. On the contrary, ponies trained with positive reinforcement showed an increased interest in humans and sought contact after training. This is especially remarkable as it was reached in a maximum of 5 sessions of 1 to 3 min (i.e. 5 to 15 min) and had lasting effects (visible after 5 months). Even learning was positively influenced by positive reinforcement. Overall, horses seem capable of associating humans to particular experiences and display extended long-term memory abilities.     

Tonal synchrony in mother–infant interaction based on harmonic and pentatonic series

This study reports the occurrence of ‘tonal synchrony’ as a new dimension of early mother–infant interaction synchrony. The findings are based on a tonal and temporal analysis of vocal interactions between 15 mothers and their 3-month-old infants during 5 min of free-play in a laboratory setting. In total, 558 vocal exchanges were identified and analysed, of which 84% reflected harmonic or pentatonic series. Another 10% of the exchanges contained absolute and/or relative pitch and/or interval imitations. The total durations of dyads being in tonal synchrony were normally distributed (M = 3.71, SD = 2.44). Vocalisations based on harmonic series appeared organised around the major triad, containing significantly more simple frequency ratios (octave, fifth and third) than complex ones (non-major triad tones). Tonal synchrony and its characteristics are discussed in relation to infant-directed speech, communicative musicality, pre-reflective communication and its impact on the quality of early mother–infant interaction and child's development.     

Cognitive aspects of congenital learned helplessness and its reversal by the monoamine oxidase (MAO)-B inhibitor deprenyl

Cognitive processes are assumed to change with learned helplessness, an animal model of depression, but little is known about such deficits. Here we investigated the role of cognitive and related functions in selectively bred helpless (cLH, n = 10), non-helpless (cNLH, n = 12) and wild type (WT, n = 8) Sprague Dawley rats. The animals were exposed to an open field for 10 min on each of two test days. On the third day, an object exploration paradigm was carried out. The animals were later tested for helplessness. Both cLH and cNLH rats were more active than WTs on the first day in the open field. Over trials, cNLH and WT rats lowered their activity less than cLH rats. This resistance-to-habituation co-varied with a resistance to develop helplessness. In cLH rats, higher ‘anxiety’ or less time spent in the center of the open field co-varied with severe helplessness. In WTs, a greater reactivity to novel objects and to a spatially relocated object predicted lower levels of helplessness. In cLH rats (n = 4–5 per group), chronic treatment with a high dose of the monoamine oxidase (MAO)-B inhibitor deprenyl (10 mg/kg; i.p.), an anti-Parkinson, nootropic and antidepressant drug, attenuated helplessness. Remarkably, helplessness reversal required the experience of repeated test trials, reminiscent of a learning process. Chronic deprenyl (10 mg/kg; i.p.) did not alter locomotion/exploration or ‘anxiety’ in the open field. In conclusion, helplessness may be related to altered mechanisms of reinforcement learning and working memory, and to abnormalities in MAO-A and/or MAO-B functioning.     

Childhood Maltreatment Increases the Risk of Intimate Partner Violence via PTSD and Anger Personality Traits in Individuals Consulting for Sexual Problems

Childhood maltreatment is a significant risk factor for the perpetration of intimate partner violence (IPV) in adulthood. This study tested, in a clinical sample, a conceptual model suggesting that childhood maltreatment contributes to the development of anger personality traits, directly and indirectly via posttraumatic stress disorder (PTSD), and that anger personality traits, in turn, are associated with IPV. Adults consulting for sex therapy (n = 114) completed self-report measures of childhood maltreatment, PTSD, anger, and IPV. Participants were exposed to high rates of childhood maltreatment (83%). Path analysis supported the hypothesized model: Exposure to child maltreatment was associated with anger personality traits, and this association was partially mediated by PTSD symptoms. Anger personality traits were highly correlated with IPV.     

The Argument for Subject Body Dualism from Transtemporal Identity Defended

In my argument for subject body dualism criticized by Ludwig I use the locution of a genuine and factual difference between two possibilities. Ludwig distinguishes three interpretations of this locution. According to his analysis the argument does not go through on any of these interpretations. In my response I agree that the argument is unsuccessful if ‘factual difference’ is understood in the first way. The second reading—according to a plausible understanding—cannot be used for the argument either. The discussion of this reading raises fundamental issues about different notions of propositional content. I disagree with Ludwig's diagnosis with respect to the third reading. Contrary to Ludwig's claim, there is no modal error involved if ‘factual difference’ is understood in the third way. Ludwig's objection to the argument according to its third reading can be answered by pointing out that every individual has its identity conditions necessarily. ¹ At this point fundamental and general metaphysical issues (concerning the link between identity conditions and the nature of ontological categories and between transworld and transtemporal identity) prove relevant. Finally, I make more explicit how ‘factual difference’ should be understood in the context of the argument (this is a fourth reading not considered by Ludwig) and explain how this reading strengthens the argument (compared to the third reading) by weakening its central premise. I conclude that Ludwig's attempt at undermining the argument from transtemporal identity for subject body dualism is unsuccessful.     

The French version of the Arnett Inventory of Sensation Seeking: Internal and predictive validity

In this study we examine the psychometric characteristics and the predictive validity of the AISS-17, the French version of the Arnett Inventory of Sensation Seeking. Two samples were used, one of which enabled us to carry out prospective monitoring over a period of six months. Our study provides data that support the validity of the AISS-17. This inventory includes the same two factors as the AISS (Novelty and Intensity). It has good concurrent and convergent validity, and its nomological network is comparable to that of the AISS and to the SSS of Zuckerman. However, our study confirms the low reliability of the AISS. We also showed that the AISS-17 has good predictive validity. We observed a significant cross-lagged effect of the AISS-17 at T1 on risk taking at T2, when controlled for age, gender and risk-taking at T1.     

Children's memory of recurring events: is the first event always the best remembered?

Three experiments were conducted to examine the effect of age (4–5 and 6–8 years) and retention interval on children's ability to remember separate occurrences of a repeated event that varied in terms of content (items, dialog, etc.) Experiment 1 explored children's ability to recall the first versus last occurrence of a series of six events, at either one week or six weeks delay. Experiments 2 and 3 explored children's ability to identify the position of items in terms of their order of presentation within the series across two retention intervals. Overall, the results revealed clear age differences in children's performance. In general, the 6‐ to 8‐year‐old children performed better on all tasks than the 4‐ to 5‐year‐old children. Further, the older children showed relatively good memory of the first and last items compared to the middle items, although the last items were more likely to be forgotten or misplaced in the sequencing tasks over time than the first items. For the younger children, the patterns of results were sometimes but not always consistent with that of the older children. The relevance and generalisability of these findings to the legal setting are discussed as well as directions for future research. Copyright © 2002 John Wiley & Sons, Ltd.     

A comparative investigation of the speech-associated coping responses reported by adults who do and do not stutter

The Behavior Checklist, a self-report test procedure, was administered to 42 adults who stutter and 76 who do not in order to investigate the number, frequency of usage, type and nature of the responses that they reportedly employ to cope with the anticipation and/or presence of speech disruption. As a group, the participants who stutter reported a significantly greater number of speech-associated coping responses and a greater use of them than their nonstuttering peers did. Moreover, factor analysis made apparent fundamental between-group differences in the type and nature of certain forms of the coping responses reported by those who stutter and those who do not. This suggests that the quantitative and qualitative differences in the coping responses of those who do and do not stutter are potentially useful with respect to differential diagnostic and therapeutic decision making. EDUCATIONAL OBJECTIVES: (1) The reader will be able to describe differences in the number, frequency and types of coping behaviors used by PWS and PWNS. (2) The reader will be able to list similarities and differences in the type and nature of coping behaviors used by PWS and PWNS. (3) The reader will be able to discuss the features and use of the Behavior Checklist, a self-report procedure for assessing the responses used by adults to cope with the anticipation and occurrence of speech disruption.
