Close online relationships in a national sample of adolescents

This paper uses data from a national survey of adolescent Internet users (N = 1,501) to describe online relationships. Fourteen percent of the youths interviewed reported close online friendships during the past year, 7% reported face-to-face meetings with online friends, and 2% reported online romances. Two hundred forty-six youths provided details about one close online relationship. Most of these relationships were with same-age peers (70%) and crossed gender lines (71%). Many intersected with face-to-face social networks because they were initiated by introductions from friends or family (32%), involved people who lived in the vicinity (26%), were known to parents (74%), included offline contact by mail or telephone (70%), or involved face-to-face meetings (41%). Few youths reported bad experiences with online friends.     

Magnetic resonance imaging changes in a patient with migraine attack and transient global amnesia after cardiac catheterization

The presence of magnetic resonance imaging (MRI) abnormalities in patients with transient global amnesia has been an interesting phenomenologic finding. Several theories surround the occurrence of this syndrome, but little is known about its true physiopathology. We present a case of transient global amnesia after cardiac catheterization associated with migraine headache and MRI changes compatible with an ischemic insult. A discussion on potential explanations for this finding is made, as well as a review of the pertinent literature.     

Using fMRI to investigate

Using fMRI, we investigated the functional organization of prefrontal cortex (PFC) as participants briefly thought of a single just-experienced item (i.e., refreshed an active representation). The results of six studies, and a meta-analysis including previous studies, identified regions in left dorsolateral, anterior, and ventrolateral PFC associated in varying degrees with refreshing different types of information (visual and auditory words, drawings, patterns, people, places, or locations). In addition, activity increased in anterior cingulate with selection demands and in orbitofrontal cortex when a nonselected item was emotionally salient, consistent with a role for these areas in cognitive control (e.g., overcoming “mental rubbernecking”). We also found evidence that presenting emotional information disrupted an anterior component of the refresh circuit. We suggest that refreshing accounts for some neural activity observed in more complex tasks, such as working memory, long-term memory, and problem solving, and that its disruption (e.g., from aging or emotion) could have a broad impact.     

Jews,race, and capitalism in the German-Jewish context

The Shoah has effectively brought to an end attempts to define the Jews racially. Yet in the half century before the 1930s, for German Jewish scholars, the racial identity of the Jews was an open question. These scholars were deeply engaged in debates over Jewish collective identity and the contemporary Jewish condition, and in these debates race played a critical role. For these scholars, race and racial theories were normative, and they exploited them for their own intellectual, political, and social purposes. Of special interest is the normative nature of racial discourse as German Jewish scholars adopted it and applied it to examine the nexus of Jews and capitalism. These scholars accepted the notion of a Jewish racial disposition for capitalism, including this notions negative aspects, while they also used it to construct a positive Jewish identity. The history of Jewish engagement with race suggests the need for a more radically historicist approach to the Jewish past, albeit this will be a most difficult scholarly challenge.Id like to thank Gil Anidjar, Nina Caputo, Steven Zipperstein, and an anonymous reviewer for their comments and criticisms of this essay.     

How perception impacts on drawings

In 3 experiments the authors investigate how errors in perception produce errors in drawings. In Experiment 1, when Shepard stimuli were shown as a pair of tables, participants made severe errors in trying to adjust 1 part of the stimulus to match the other. When the table legs were removed, revealing a pair of parallelograms with minimal perspective cues, the illusion was weaker. The authors predicted that participants would err when drawing the table but not the parallelogram stimuli. The results of Experiment 2 support the prediction and establish a direct link between degree of perceptual distortion of the table stimuli and the severity of error in drawing. When drawing only the right-hand part of the figure, participants also erred to a greater degree in drawing the table than the parallelogram (Experiment 3). Collectively, the results suggest that perceptual distortion is linked with errors in drawing the table stimuli.     

Anger, anxiety, and depression as risk factors for cardiovascular disease: the problems and implications of overlapping affective dispositions

Several recent reviews have identified 3 affective dispositions--depression, anxiety, and anger-hostility--as putative risk factors for coronary heart disease. There are, however, mixed and negative results. Following a critical summary of epidemiological findings, the present article discusses the construct and measurement overlap among the 3 negative affects. Recognition of the overlap necessitates the development of more complex affect-disease models and has implications for the interpretation of prior studies, statistical analyses, prevention, and intervention in health psychology and behavioral medicine. The overlap among the 3 negative dispositions also leaves open the possibility that a general disposition toward negative affectivity may be more important for disease risk than any specific negative affect.     

A Relational Psychodynamic Perspective on Assimilative Integration

In this paper we discuss recent advances in relational psychoanalytic thinking, and demonstrate how an assimilative approach to integration can be based on this theoretical and clinical model. We describe 3 instances in which active interventions may be used to enhance relationally oriented, psychoanalytic work: by impacting on relationships outside of therapy that maintain pathological patterns, by filling in intrapsychic deficits, and by supporting the patient's active efforts at change. We provide clinical examples to illustrate each of these points.     

Equipoise: beyond rehabilitation?

Challenging the interpretation of Charles Fried's use of "equipoise" presented by Paul Miller and Charles Weijer in a recent issue of the Kennedy Institute of Ethics Journal, this commentary argues that Fried was in no way promoting the concept of equipoise. In fact, his key point was that patients have a right to know and to make their own decisions about participation in clinical trials, regardless of equipoise, however it is defined.
