Higher visuo-Attentional Demands of Multiple Object Tracking (MOT) Lead to A Lower Precision in Pointing Movements

Multiple object tracking (MOT) requires visually attending to dynamically moving targets and distractors. This cognitive ability is based on perceptual-attentional processes that are also involved in goal-directed movements. This study aimed to test the hypothesis that MOT affects the motor performance of aiming movements. Therefore, the participants performed pointing movements using their fingers or a computer mouse that controlled the movements of a cursor directed at the targets in the MOT task. The precision of the pointing movements was measured, and it was predicted that a higher number of targets and distractors in the MOT task would result in a lower pointing precision. The results confirmed this hypothesis, indicating that MOT might influence the performance of motor actions. The potential factors underlying this influence are discussed.     

Writing,Reading, and Listening Differentially Overload Working Memory Performance Across the Serial Position Curve

Previous research has assumed that writing is a cognitively complex task, but has not determined if writing overloads Working Memory more than reading and listening. To investigate this, participants completed three recall tasks. These were reading lists of words before recalling them, hearing lists of words before recalling them, and hearing lists of words and writing them as they heard them, then recalling them. The experiment involved serial recall of lists of 6 words. The hypothesis that fewer words would be recalled overall when writing was supported. Post-hoc analysis revealed the same pattern of results at individual serial positions (1 to 3). However, there was no difference between the three conditions at serial position 4, or between listening and writing at positions 5 and 6 which were both greater than recall in the reading condition. This suggests writing overloads working memory more than reading and listening, particularly in the early serial positions. The results show that writing interferes with working memory processes and so is not recommended when the goal is to immediately recall information.     

BEFORE BABEL: REFLECTIONS ON READING AND TRANSLATING FREUD

The author offers some thoughts on reading and teaching Freud, on translating Freud, on translation in general, and on a possible kinship between translation and the psychoanalytic process. His reading of Freud's works, and the years he spent translating them into Hebrew and editing Hebrew editions of his writings, have made a deep and salient impression on his personal psychoanalytic palimpsest. The author began this labor prior to his psychoanalytic training and has no doubt that, to this day, the experience greatly shapes not only his attitude toward Freud himself, but also the nature of how he listens to patients and the way he thinks and writes about psychoanalysis.     

Object relational disturbances that may underlie the diagnosis of attention-deficit disorder in adults

Extensive case material is used to show how some adult patients who have been diagnosed with and medicated for attention-deficit disorder (ADD) may be actually suffering from underlying unconscious object relational conflicts that interfere with their ego-functioning, creating an inhibition of basic concentration, focus, expression, and learning. Early childhood experiences of trauma and neglect can create destructive patterns of projective identification based paranoia, guilt, and intense anxiety. The author proposes that these patients have to sacrifice their own identity, psychological organization, and ability to learn or teach in order to keep the peace with others. In order to avoid conflict, difference, and uncertainty, these patients do whatever they can to placate, please, and not disturb the object. However, they often end up extremely resentful, oppositional, and passive-aggressive in reaction. The overwhelming anxiety these patients experience in relationship to the object and to their own internalized demanding critic blocks their ability to learn and grow. In addition, new knowledge, mastery, and creativity are seen as dangerous, forced upon them, or bringing unsafe attention to them. So, in defense, they adapt an inert, scattered, or formless way of living to keep under the radar. This paper advocates the psychoanalytic treatment of such internal conflicts over the popular diagnosis of ADD. Difficulties of learning, attention, concentration, and organization can be better understood and treated as a set of core psychological issues open to gradual working through and healing rather than neurological defects that can only be controlled or managed with strong medication and behavioral exercises.     

Body-ownership for actively operated non-corporeal objects

Rubber-hand and virtual-hand illusions show that people can perceive body ownership for objects under suitable conditions. Bottom-up approaches assume that perceived ownership emerges from multisensory matching (e.g., between seen object and felt hand movements), whereas top-down approaches claim that novel body parts are integrated only if they resemble some part of a permanent internal body representation. We demonstrate that healthy adults perceive body ownership for a virtual balloon changing in size, and a virtual square changing in size or color, in synchrony with movements of their real hand. This finding is inconsistent with top-down approaches and amounts to an existence proof that non-corporeal events can be perceived as body parts if their changes are systematically related to one’s actions. It also implies that previous studies with passive-stimulation techniques might have underestimated the plasticity of body representations and put too much emphasis on the resemblance between viewed object and real hand.     

The countertransference impact of autistic defence in an otherwise neurotic patient

This paper investigates the question of why, in the psychoanalytic psychotherapy of a patient with encapsulated autistic pathology, the steady maintenance of a therapeutically neutral stance can be especially difficult. Transference and countertransference vicissitudes are examined. The author notices that the patient's intolerance of ‘opposites’ (cf. Tustin, 1986), combined with extreme antipathy to having that intolerance noticed, can elicit corresponding, and potentially destabilizing, countertransference reactions. These reactions comprise an unstable tension between co‐existing pressures towards fusion with, or expulsion of, the patient, their co‐existence under further pressure to remain unnoticed. Until perceived, this state of affairs risks collusion with the pressure either to merge with or to expel the patient, and compromises the capacity to notice the detail of the transference process and even to notice co‐existent positive and negative transference images. Detailed clinical illustration is given, including a session where it was difficult to notice the patient's experience of a couple as a combined object. The author finds these observations of bipolar countertransference tensions illuminated by Green's concepts of positive and negative narcissism and of the disobjectalizing function, and specifically accounted for by Ribas's theory of autism as radical drive defusion.     

Efficacy of self-administered treatments for pathological academic worry: A randomized controlled trial

Research on treatments for reducing pathological worry is limited. In particular, academic worry is a common theme in generalized anxiety disorder (GAD) samples as well as non-clinical student samples. Given the high cost of anxiety disorders to society, research is needed to examine the efficacy of self-administered treatments designed to reduce pathological worry. The primary goal of this study was to investigate the benefits of three self-administered interventions for reducing academic worry. College students (N = 113) experiencing clinically significant academic worry were randomized to either: (a) worry exposure (WE); (b) expressive writing (EW); (c) relaxation consisting of pulsed audio-photic stimulation (APS); or (d) waitlist control (WLC). Participants were instructed to practice their interventions three times per week for one month and completed home practice logs online to track treatment adherence. Academic worry, general anxiety, and perceived stress were assessed at baseline and post-treatment. Academic worry and general anxiety were also assessed at a three-month follow-up. Those assigned to the WE and APS conditions showed significant improvement relative to EW and WLC at post-treatment. All treatment conditions showed continued improvement by follow-up, with no between-group differences. Treatment and public health implications are discussed.     

Infants’ recognition of objects using canonical color

We explored infants’ ability to recognize the canonical colors of daily objects, including two color-specific objects (human face and fruit) and a non-color-specific object (flower), by using a preferential looking technique. A total of 58 infants between 5 and 8 months of age were tested with a stimulus composed of two color pictures of an object placed side by side: a correctly colored picture (e.g., red strawberry) and an inappropriately colored picture (e.g., green-blue strawberry). The results showed that, overall, the 6- to 8-month-olds showed preference for the correctly colored pictures for color-specific objects, whereas they did not show preference for the correctly colored pictures for the non-color-specific object. The 5-month-olds showed no significant preference for the correctly colored pictures for all object conditions. These findings imply that the recognition of canonical color for objects emerges at 6 months of age.
