Differences in cortical activity related to motor planning between experienced guitarists and non-musicians during guitar playing

The influence of motor skill learning on movement-related brain activity was investigated using electroencephalography. Previous research has indicated that experienced performers display movement-related cortical potentials (MRCPs) of smaller amplitude and later onset compared to novices. Unfortunately, previous studies have lacked ecological validity with experimenters recording the MRCP prior to simple motor tasks and applying the results to more complex motor skills. This study replicated previous research using an ecologically valid motor skill; recording the MRCP from a group of experienced guitarists and a control group of non-musicians while they played a simple scale on the guitar. Results indicated no difference between groups in early motor planning. In contrast, the later, negative slope and motor potential components were of smaller amplitude and the negative slope began later in the experienced guitarists. The data may indicate that, for experienced guitarists, a reduced level of effort is required during the motor preparation phase of the task. These findings have implications for musical instrument learning as well as motor skill acquisition in general.     

Electrophysiological evidence for greater attention to threat when cognitive control resources are depleted

In this study, we investigated the time course of attentional bias for threat-related (angry) facial expressions under conditions of high versus low cognitive (working memory) load. Event-related potential (ERP) and reaction time (RT) data were recorded while participants viewed pairs of faces (angry paired with neutral face) displayed for 500 ms and followed by a probe. Participants were required to respond to the probe while performing a concurrent task of holding in working memory a sequence of digits that were either in the same order (low memory load) or in a random mixed order (high memory load). The ERP results revealed that higher working memory load resulted in enhanced lateralized neural responses to threatening relative to neutral faces, consistent with greater initial orienting of attention to threatening faces (early N2pc: 180–252 ms) and enhanced maintenance of processing representations of threat (late N2pc, 252–320 ms; SPCN, 320–500 ms). The ERP indices showed significant positive relationships with each other, and also with the behavioral index of attentional bias to threat (reflected by faster RTs to probes replacing angry than neutral faces at 500 ms), although the latter index was not significantly influenced by memory load. Overall, the findings indicate that depletion of cognitive control resources, using a working memory manipulation, increases the capacity of task-irrelevant threat cues to capture and hold attention.     

Seeing,sitting and lying down: Reflections on the role of visual communication in analytic therapy

The paper develops the post-Winnicottian psychoanalyst Kenneth Wright's theory of the face which he sees as insufficiently theorized psychoanalytically. As compared with the breast, the face is intrinsically a vehicle for generating meaning and representation, rather than satisfying bodily need. Infants see themselves reflected back in the mother's facial expressions and this helps to build up self-representation in the child's mind's eye. Other Attachment-influenced research findings about care-giver/infant facial communication are also described: partial contingency, triangulation and rupture/repair. The relevance of this to the question of chair or couch-based therapy is discussed. The discussion is illustrated by a consideration of the work of the visual artist Louise Bourgeois.     

The involvement of distinct visual channels in rapid attention towards fearful facial expressions

This paper reports five experiments demonstrating that the low spatial frequency components of faces are critical to the production of rapid attentional responses towards fearful facial expressions. In our main experiments, low spatial frequency (LSF) or high spatial frequency (HSF) face pairs, consisting of one fearful and one neutral expression, were presented on a computer screen for a brief period. Participants were required to identify as quickly as possible the orientation of a bar target that immediately replaced one of the faces. Responses were faster when targets replaced the location of LSF fearful faces, compared with LSF neutral faces. By contrast, there were no differences between responses to targets replacing HSF fearful versus HSF neutral faces. This facilitation in spatial orienting occurred specifically with short time intervals between faces and target, and is consistent with a rapid processing of fear cues from LSF inputs that can serve to guide attention towards threat events.     

Does trauma memory play a role in the experience of reporting sexual assault during police interviews? An exploratory study

A recent study indicated that 94.4% of reported sexual assault cases in the UK do not result in successful legal prosecution, also known as the rate of attrition (Kelly, Lovett, & Regan, 2005 Kelly, L., Lovett, J. and Regan, L. 2005. A gap or a chasm? Attrition in rape cases, London: Home Office.  [Google Scholar]). Scant research has examined the role of trauma-related psychological processes in attrition. Victims of sexual assault (N =22) completed questions about peri-traumatic dissociation, trauma memory fragmentation, account incoherence during police interview, and likelihood of proceeding with legal cases. Higher levels of dissociation during sexual assault were associated with participants reporting more fragmented trauma memories. Memory fragmentation was associated with participants indicating that they provided more incoherent accounts of trauma during police interview. Importantly, people who viewed themselves as providing more incoherent accounts predicted that they would be less likely to proceed with their legal cases. The findings suggest trauma impacts on memory, and these trauma-related disruptions to memory may paradoxically contribute to attrition.     

Research Trails and the Creative Spirit: Can Historical Case Studies Integrate the Short and Long Timescales of Creative Activity?

In the study of scientific creativity, the purposes of cognitive scientists and of historians of science overlap but are far from congruent. Historical cases are only one of many forms of evidence that cognitive scientists bring together to arrive at general conclusions about the creative processes. Historians seek to reconstruct the investigative enterprises of particular scientists. Generalizations about creativity are useful to historians mainly as one of various means to interpret the work of those particular scientists. This article presents the argument that the extent to which these two goals can be complementary depends largely (a) on how large the gap is between the duration of the thought processes that cognitive scientists examine and the limits of resolution to which historians can penetrate in following the temporal progression of a subject's thought and work and (b) on the level of temporal organization of these thoughts and actions most revealing of their creative nature.     

A model of intervention at a psychoanalytic parent/child drop-in group in a poor district of Lima,Peru

The psychoanalytically informed work of a team of workers at a drop-in centre for families in a poor district of Lima is described. Interventions involve: accepting, connecting, playing and empowering. Clinical vignettes are used to illustrate the ways in which these interventions aim to help families. The acceptance of difficult feelings provides containment for attendees; acceptance of individuality fosters a greater capacity to mentalise. In viewing the patient as the relation between parents and child, connections are forged and encouraged between family members. Questions and difficulties that parents express are relayed to children in a palatable way, modelling the inclusion of children in the family dialogue. Playing is advocated and encouraged and elements of the fluid ‘frame’ impact on how playful interactions are shaped. Empowering takes place through encouraging reflexivity and dissolving fantasies of passivity. Questions about child behaviour are reflected back to the questioner or to other attendees, and pathologising diagnostic terms, if raised by families, are challenged and investigated, rather than accepted, encouraging families to carry on thinking. The implications of this model of work are discussed.     

Action Observation and Imagery Training Improve the Ease With Which Athletes Can Generate Imagery

Imagery can improve sport performance, although its efficacy is mediated by the ease with which athletes can generate images. Establishing techniques that improve this imagery ability factor is desirable to enhance the effectiveness of imagery interventions. Twenty-seven club-level female golfers were assigned to imagery, action observation, or physical practice training groups (n = 9). Changes in image generation ease were assessed using the Revised Movement Imagery Questionnaire over an 8-week period. Imagery and action observation training were both effective in improving aspects of imagery ability. Action observation can provide sport psychologists with an effective tool for improving visual imagery ability in athletes.     

Positive involuntary autobiographical memories: You first have to live them

Involuntary autobiographical memories (IAMs) are typically discussed in the context of negative memories such as trauma ‘flashbacks’. However, IAMs occur frequently in everyday life and are predominantly positive. In spite of this, surprisingly little is known about how such positive IAMs arise. The trauma film paradigm is often used to generate negative IAMs. Recently an equivalent positive film was developed inducing positive IAMs (Davies, Malik, Pictet, Blackwell, & Holmes, 2012). The current study is the first to investigate which variables (emotional reaction to the film; recognition memory of the film; participant characteristics) would best predict the frequency of positive IAMs. Higher levels of positive mood change to the film were significantly associated with the number of positive IAMs recorded in the subsequent week. Results demonstrate the importance of positive emotional reaction at the time of an event for subsequent positive IAMs.
