Attachment Representations and Maternal Confidence: The Mediating Role of Postnatal Depressive Symptoms and Negative Thoughts

Attachment security can act as an inner resource to promote women’s adjustment to motherhood. However, the mechanisms explaining the relationship between attachment representations and maternal adaptation outcomes are not well understood. This study aimed to examine the direct and indirect effects of attachment representations on maternal confidence, through postpartum negative automatic thoughts and depressive symptoms. The sample consisted of 387 postpartum women who completed a cross-sectional online survey including measures of attachment representations, depressive symptoms, postpartum negative automatic thoughts and maternal confidence. Our results showed a significant relationship between more insecure attachment representations and higher depressive symptoms (p?<?.001), but also with more frequent postpartum negative automatic thoughts (p?<?.001); depressive symptoms and postpartum negative automatic thoughts were also inversely associated with women’s maternal confidence (p?<?.001). Moreover, indirect effects of attachment representations on maternal confidence were found, but only through postpartum negative thoughts [attachment-related anxiety: 95% CI?=??0.03/?0.01; attachment-related avoidance: 95% CI?=??0.05/?0.01]. The results of the present study emphasize the important role of the cognitive component of depressive symptomatology (postpartum negative automatic thoughts) in the relationship between attachment representations and maternal confidence, allowing to draw specific implications. We highlight the implications for clinical practice during the perinatal period to address both negative thoughts and women’s maternal confidence.     

The Guise of the Guise of the Bad

It is undeniable that human agents sometimes act badly, and it seems that they sometimes pursue bad things simply because they are bad. This latter phenomenon has often been taken to provide counterexamples to views according to which we always act under the guise of the good (GG). This paper identifies several distinct arguments in favour of the possibility that one can act under the guise of the bad. GG seems to face more serious difficulties when trying to answer three different, but related, arguments for the possibility of acting under the guise of the bad. The main strategies available to answer these objections end up either undermining the motivation for GG or failing to do full justice to the nature of perverse motivation. However, these difficulties turn out to be generated by focusing on a particular version of GG, what I call the “content version”. But we have independent reasons to prefer a different version of GG; namely, the “attitude version”. The attitude version allows for a much richer understanding of the possibility of acting on what we conceive to be bad. Drawing on an analogy with theoretical akrasia and theoretical perversion, I try to show how the attitude version can provide a compelling account of perverse actions.     

Development of rule-based eye-hand-decoupling in children and adolescents

In the present study, we characterize how the ability to decouple guiding visual information from a motor action emerges during childhood and adolescence. Sixty-two participants (age range 8–15 yrs.) completed two eye-hand coordination tasks. In a direct interaction task, vision and motor action were in alignment, and participants slid their finger along a vertical touch screen to move a cursor from a central target to one of four peripheral targets. In an eye-hand-decoupled task, eye and hand movements were made in different planes and cursor feedback was 180° reversed. We analyzed whether movement planning, timing and trajectory variables differed across age in both task conditions. There were no significant relationships between age and any movement planning, timing, or execution variables in the direct interaction task. In contrast, in the eye-hand-decoupled task, we found a relationship between age and several movement planning and timing variables. In adolescents (13–15 yrs.), movement planning and timing was significantly shorter than that of young children (8–10 yrs.). Eye-hand-decoupled maturation emerged mainly during late childhood (11–12 yrs.). Notably, we detected performance differences between young children and adolescents exclusively during the eye-hand decoupling task which required the integration of rule-based cognitive information into the motor action. Differences were not observed during the direct interaction task. Our results quantify an important milestone for eye-hand-decoupling development in late childhood, leading to improved rule-based motor performance in early adolescence. This eye-hand-decoupling development may be due to frontal lobe development linked to rule-based behavior and the strengthening of fronto-parietal networks.     

Eye movements disrupt episodic future thinking

Remembering the past and imagining the future both rely on complex mental imagery. We considered the possibility that constructing a future scene might tap a component of mental imagery that is not as critical for remembering past scenes. Whereas visual imagery plays an important role in remembering the past, we predicted that spatial imagery plays a crucial role in imagining the future. For the purpose of teasing apart the different components underpinning scene construction in the two experiences of recalling episodic memories and shaping novel future events, we used a paradigm that might selectively affect one of these components (i.e., the spatial). Participants performed concurrent eye movements while remembering the past and imagining the future. These concurrent eye movements selectively interfere with spatial imagery, while sparing visual imagery. Eye movements prevented participants from imagining complex and detailed future scenes, but had no comparable effect on the recollection of past scenes. Similarities between remembering the past and imagining the future are coupled with some differences. The present findings uncover another fundamental divergence between the two processes.     

Just lying there,remembering: Improving recall of prose in amnesic patients with mild cognitive impairment by minimising interference

The hallmark of amnesia is poor explicit long‐term memory along with normal short‐term memory. It is often stated that information encountered by amnesic patients is forgotten within 1 minute of presentation. However, previous work has not distinguished between forgetting as a function of time versus the interfering material occupying that time. We show that there is a marked benefit of reduced interference in amnesic patients with mild cognitive impairment (MCI), a condition that is characterised by anterograde amnesia in the absence of other neuropsychological deficits and carries an increased risk for Alzheimer's disease. The result suggests that long‐term memory is encoded in these patients to a greater extent than had been realised but that their memory is highly vulnerable to interference.     

A Woman Is Being Beaten - Issues on Violence and Femininity

What kind of contributions can psychoanalysis make toward issues that concern violence and femininity, specifically the violence that women establish in the relations with the significant other and themselves? In this paper, the authors attempt to answer this question by dealing with concepts such as instinct, masochism and enjoyment. Additionally, they recognize the act of psychoanalytic listening as a genuine and valid manner of getting the unconscious to speak. This act of listening can be practiced either in the traditional psychoanalytic setting of private offices or in psychoanalysis applied to public institutions, for the principal tool is language as it permeates human relationships and proportions the structure of the unconscious mind.     

Entrevista con Julián de Ajuriaguerra

RESUMEN

En esta entrevista Julián de Ajuriaguerra describe su historia científica desde que era interno en hospitales psiquiátricos y alumno de Thomas y Lhermitte, comentando los trabajos que realizó con adultos, ancianos y dementes aunque su interés estuviese desde un principio en los niños. Responde, entre otras, a cuestiones tales como si lo biológico se complementa con lo social en el desarrollo, cómo son los vínculos de los padres con el niño, cuál es su posición respecto al psicoanálisis, si es necesaria la interdisciplinariedad para hacer psicología o qué opina del problema de los estadios. También realiza un balance del estado actual de la psicomotricidad, ejemplifica qué entiende por “diálogo tónico” y explica las diferencias entre los juegos de niños y niñas de siete, ocho y nueve años, admitiendo la distinta organización tónica de los sexos. Por último el autor se centra en el trabajo clínico, ofreciendo sugerencias para aquéllos que empiezan a llevarlo a cabo en España. Los comentarios que Ana María Pardo y Ángel Rivière realizan del autor y su obra introducen esta entrevista.     

Lack of color integration in visual short-term memory binding

Bicolored objects are retained in visual short-term memory (VSTM) less efficiently than unicolored objects. This is unlike shape–color combinations, whose retention in VSTM does not differ from that observed for shapes only. It is debated whether this is due to a lack of color integration and whether this may reflect the function of separate memory mechanisms. Participants judged whether the colors of bicolored objects (each with an external and an internalcolor) were the same or different across two consecutive screens. Colors had to be remembered either individually or in combination. In Experiment 1, external colors in the combined colors condition were remembered better than the internal colors, and performance for both was worse than that in the individual colors condition. The lack of color integration observed in Experiment 1 was further supported by a reduced capacity of VSTM to retain color combinations, relative to individual colors (Experiment 2). An additional account was found in Experiment 3, which showed spared color–color binding in the presence of impaired shape–color binding in a brain-damaged patient, thus suggesting that these two memory mechanisms are different.
