Effects of event rate and display time on sustained attention in hyperactive,normal, and control children

Two experiments were conducted to determine whether hyperactive boys have a unique deficit in sustained attention. Groups with DSM-III diagnoses of attention deficit disorder (ADDH), conduct disorder (CD), ADDH+CD, and learning disorder were compared with normal controls on the Continuous Performance Task. In Experiment 1, stimulus presentation rate (stimulus onset asynchrony, SOA) and display time were varied to manipulate attentional demand, and speed and accuracy of performance were measured. The ADDH group was uniquely affected, with less accurate performance at the fastest and slowest SOA. To distinguish the effects of time on task and SOA, the duration of each SOA condition was held constant in Experiment 2. The poorer performance of the ADDH group at the fastest SOA was no longer evident. This finding indicates that the deficit of sustained attention in boys who have ADDH is associated with a greater susceptibility to refractory effects, which is influenced by practice.This research was supported by the Ontario Mental Health and Ruth Schwartz Foundations through a graduate fellowship awarded to P.

RAISING FEMINISTS

This article considers the reasons for raising feminist children, how this concept might be operationalized, and what the correlates of such gender-flexible patterns might be. The data pertinent to gender-role acquisition and gender flexibility are drawn from an ongoing longitudinal study of over 200 children and their families that originated when the children were 6 months of age and continues until they enter school at age 6. Results suggest that despite the overdetermined and inevitable learning of gender stereotypes, variation exists in the degree to which even young children subscribe to the stereotypes. These variations seem to relate to some realms of parental behavior.     

QUALITIES MIDLIFE WOMEN DESIRE IN THEIR SEXUAL RELATIONSHIPS AND THEIR CHANGING SEXUAL RESPONSE

The present study focused on the association between the particular sexual qualities midlife women desired in themselves and their husbands and the changes in sexual response they were experiencing. In a U.S. sample of 280 women participating in the ongoing Midlife Women's Health Survey, 40% reported a change in their sexual response, more often as decrements than increases, although desiring more nongenital touching was frequently noted. Respondents wanted more change in their own than in their partners' sexual qualities. In addition, the desire to change sexual qualities in oneself and in one's husband was significantly related to many changes in sexual responsivity. These findings are discussed in the context of a woman-defined sexuality at midlife.     

Education as Free Use: Giorgio Agamben on Studious Play,Toys, and the Inoperative Schoolhouse

In this essay, I argue that the work of Giorgio Agamben provides us with a theory of studious play which cuts across many of the categories that polarize educational thought. Rather than either ritualized testing or constructivist playfulness, Agamben provides a model of what he refers to as studious play—a practice which suspends the logic of both ritual and play. In order to explore this notion of studious play, I first articulate Agamben’s fleeting remarks on the topic with an important problematic found in his early, literary work: transmission. If ritual transmits cultural traditions to ensure continuity with the past, and play as constructivist invention makes such transmission impossible, then studious play transmits transmissibility itself as a pure potentiality. Studious play accomplishes this peculiar educational task by suspending without destroying traditional things: laws, signs, and so on. I end the essay with a consideration of the ontological status of suspended things, arguing that they are transformed into toys via the action of study. Finally, I give a literary example of studious play found in Robert Walser’s novel Jakob von Gunten in which the school itself is imagined to be a kind of toy.     

Depression and heart rate variability in cardiac rehabilitation patients: exploring the roles of physical activity and fitness

Cardiac patients with depression have shown altered autonomic nervous system functioning, expressed as reduced heart rate variability. This may be associated with poorer physical fitness and less physical activity among depressed patients. These relationships were explored among patients enrolled in outpatient cardiac rehabilitation. 22 depressed and 22 nondepressed patients, matched for sex and age, were assessed at enrollment. The Beck Depression Inventory and structured interviews were used to measure depression. Patients completed ambulatory monitoring of ECG (i.e., Holter) and physical activity, as well as a treadmill stress test. Depression was associated with several measures of heart rate variability. Activity and fitness were lower among the depressed patients. Although exploratory, accounting for activity and fitness attenuated the relationship between depression and heart rate variability. This suggests that altered fitness and activity may help explain altered autonomic tone that characterizes patients with cardiovascular diseases who are psychologically depressed.     

Perceptual modification of sensitivity (d′): Modifying temporal resolution by the consistency of the spatial configuration

The major question in this study was whether perceptual modifications are basic alterations in a sensory system or changes in the S’s criterion. Four Ss were given prolonged training with a particular two-lined stimulus, deciding whether the stimulus had been presented in one continuous presentation or in two successive presentations with a temporal gap. The results confirmed the hypothesis, generated from modifications in visual cells, that the S’s sensitivity (d′) to a two-lined stimulus could be disrupted by the presentation of one original line with a new line. In contrast, two entirely new lines had little effect on the S’s sensitivity. A discussion of the results also indicated that temporal resolution must be a plastic process which depends on the consistency of the spatial configuration as well as temporal parameters.     

Our Immigration and Human Rights Work Group in Action: Psychoanalysts Evaluating Asylum Seekers,Trauma and Family Devastation

ABSTRACT

This paper presents the story of a family of four refugees from Central America seeking asylum in the United States, and of the experience of a group of psychoanalysts, members of the New York University Postdoctoral Program Immigration and Human Rights Work Group, who evaluated each member of the family and wrote affidavits in support of their applications for asylum. The work described provides an example of how clinicians can apply their skills and understandings outside the consulting room to address the dire needs of refugees who have fled from their homes. We discuss the process of refugees seeking asylum and the role of a psychological evaluation in the asylum process. We elaborate on the content and process of the evaluations of each member of the family with a focus on the trauma suffered and its sequelae on two school-aged children, their adolescent aunt, and their courageous and protective mother. We also address the analysts’ experience of doing psychological evaluations and writing affidavits for asylum seekers who have experienced trauma.
