Rehearsal in serial memory for visual-spatial information: Evidence from eye movements

It is well established that rote rehearsal plays a key role in serial memory for lists of verbal items. Although a great deal of research has informed us about the nature of verbal rehearsal, much less attention has been devoted to rehearsal in serial memory for visual-spatial information. By using the dot task—a visual-spatial analogue of the classical verbal serial recall task—with delayed recall, performance and eyetracking data were recorded in order to establish whether visual-spatial rehearsal could be evidenced by eye movement. The use of eye movement as a form of rehearsal is detectable (Experiment 1), and it seems to contribute to serial memory performance over and above rehearsal based on shifts of spatial attention (Experiments 1 and 2).     

Aripiprazole-related tardive dyskinesia

The low prevalence of extrapyramidal symptoms associated with atypical antipsychotics has led to their widespread use during the past decade. Aripiprazole, the newest medication in this class, has been associated with extrapyramidal symptoms (eg, akathisia) and with improvement of tardive dyskinesia (TD), but to date it has not been associated with the development of TD. We report a case of TD associated with the use of aripiprazole 15 mg/day for 18 months for refractory depression. Symptoms of TD resolved within several weeks of discontinuation of aripiprazole.     

Individual and social determinants of winning bids in online auctions

• Online auctions have grown in popularity since the inception of eBay in 1995. Yet despite the phenomenal growth, little is understood about the individual and collective motivations of consumers that lead to higher bids and ultimately, higher profits. This research reframes auction theory in terms of consumer behavior theory and uses observational data to assess bidder‐generated behavior in response to seller‐generated decisions. Results suggest that an increased number of visual cues (pictures) influences bids placed early in the auction and that those early bids generate activity among other bidders, subsequently resulting in higher winning bids. In addition, our findings indicate that the starting price, as determined by the seller, also impacts the final winning bid. Research and seller implications are offered, as are future directions for research in studying this still new phenomenon.

Ethics and professionalism: what does a resident need to learn?

Training in ethics and professionalism is a fundamental component of residency education, yet there is little empirical information to guide curricula. The objective of this study is to describe empirically derived ethics objectives for ethics and professionalism training for multiple specialties. Study design is a thematic analysis of documents, semi-structured interviews, and focus groups conducted in a setting of an academic medical center, Veterans Administration, and community hospital training more than 1000 residents. Participants were 84 informants in 13 specialties including residents, program directors, faculty, practicing physicians, and ethics committees. Thematic analysis identified commonalities across informants and specialties. Resident and nonresident informants identified consent, interprofessional relationships, family interactions, communication skills, and end-of-life care as essential components of training. Nonresidents also emphasized formal ethics instruction, resource allocation, and self-monitoring, whereas residents emphasized the learning environment and resident-attending interactions. Conclusions are that empirically derived learning needs for ethics and professionalism included many topics, such as informed consent and resource allocation, relevant for most specialties, providing opportunities for shared curricula and resources.     

Backward recall and benchmark effects of working memory

Working memory was designed to explain four benchmark memory effects: the word length effect, the irrelevant speech effect, the acoustic confusion effect, and the concurrent articulation effect. However, almost all research thus far has used tests that emphasize forward recall. In four experiments, we examine whether each effect is observable when the items are recalled in reverse order. Subjects did not know which recall direction would be required until the time of test, ensuring that encoding processes would be identical for both recall directions. Contrary to predictions of both the primacy model and the feature model, the benchmark memory effect was either absent or greatly attenuated with backward recall, despite being present with forward recall. Direction of recall had no effect on the more difficult conditions (e.g., long words, similar-sounding items, items presented with irrelevant speech, and items studied with concurrent articulation). Several factors not considered by the primacy and feature models are noted, and a possible explanation within the framework of the SIMPLE model is briefly presented.     

Interfacial waves between piezoelectric and piezomagnetic half-spaces with magneto-electro-mechanical imperfect interface

Abstract

We study the propagation of shear horizontal waves between the interface of piezoelectric and piezomagnetic half-spaces with a magneto-electro-mechanical imperfect contact. Mechanical, electrical and magnetical imperfections are modelled by means of a spring, a capacitor and a inductor, respectively. A general expression for the dispersion relation not reported previously in literature is given in an explicit form, with the diverse limit cases analysed in detail. In some of these limit cases, new expressions are also obtained which predict the existence of interfacial waves. In the other cases, when already reported results exist, a comparison with them is done. Some physical interpretations are derived from the limit cases. The influence of mechanical, electrical and magnetical imperfect contacts are shown in some numerical examples.     

Opening What Has Been Closed,Relaxing What Has Been Clenched: Dissociation and Enactment Over Time in Committed Relationships

I use dissociation and the concept of the multiple self to link Mitchell's profound insight with Goldner's critique. In the process, I use the idea of dissociation to think about the nature of different kinds of long-term relationships.     

“One Never Knows,Do One?”: Commentary on Paper by the Boston Change Process Study Group

I discuss the work of the Boston Change Process Study Group, focusing on the paper in this issue of Psychoanalytic Dialogues, but also addressing broader issues across the range of their work. After describing the considerable similarities between their views and mine, I focus on three areas about which I have questions: the concept and clinical use of mutual enactment, BCPSG's use of nonlinear dynamic systems theory, and certain problems revolving around science and social construction.     

The Fusion of Horizons: Dissociation,Enactment, and Understanding

All understanding is context dependent, and one of the most significant contexts for clinical purposes is the self-state. How we understand the other, and ourselves, depends on the state(s) we occupy. Dissociations between an analyst's self-states can, therefore, limit or impede understanding of the analysand by depriving the analyst of a fitting context within which to grasp what the analysand says and does. Clinical understanding may require the breach of such dissociations. I lay out some of the implications of thinking about transference and countertransference along these lines, with detailed examples illustrating the consequences of the analyst's dissociations and their eventual resolutions. Among the advantages of this way of thinking is that it amounts to a psychoanalytic account of the hermeneutic circle.     

The Interpersonal Field: Its Place in American Psychoanalysis

Today the concept of the interpersonal field, while seldom credited to those who created it, is widely used in psychoanalysis. After reviewing how the concept of the field defines interpersonal and relational psychoanalysis, I take up the rejection of the idea in American mainstream psychoanalysis in the decades just after it was proposed by Sullivan and Fromm, why that rejection took place, and how the entire discipline of psychoanalysis in North America might have fared if the idea had been widely recognized earlier than it was.
