Dual-tasking alleviated sleep deprivation disruption in visuomotor tracking: an fMRI study

Effects of dual-responding on tracking performance after 49-h of sleep deprivation (SD) were evaluated behaviorally and with functional magnetic resonance imaging (fMRI). Continuous visuomotor tracking was performed simultaneously with an intermittent color-matching visual detection task in which a pair of color-matched stimuli constituted a target and non-matches were non-targets. Tracking error means were binned time-locked to stimulus onset of the detection task in order to observe changes associated with dual-responding by comparing the error during targets and non-targets. Similar comparison was made with fMRI data. Our result showed that despite a significant increase in the overall tracking error post SD, from 20 pixels pre SD to 45 pixels post SD, error decreased to a minimum of about 25 pixels 0-6s after dual-response. Despite an overall reduced activation post SD, greater activation difference between targets and non-targets was found post SD in task-related regions, such as the left cerebellum, the left somatosensory cortex, the left extrastriate cortex, bilateral precuneus, the left middle frontal gyrus, and the left motor cortex. Our results suggest that dual-response helps to alleviate performance impairment usually associated with SD. The duration of the alleviation effect was on the order of seconds after dual-responding.     

Relational Psychoanalysis and the Inner Life: Commentary on Cooper,Corbett, and Seligman

Relational analysts know that their experience feels private and contemplative during a significant portion of their working hours. A consideration of the inner life, both the analyst’s and the patient’s, is part of relational praxis. Yet relational analysts also recognize that they are continuously involved with their patients, even at those very same quiet moments. Cooper, Corbett, and Seligman recognize both these parts of relational clinical work and argue that both are necessary. Making this argument explicit is important for its own sake, but also because analysts from other schools sometimes write as if there is no place in relational clinical practice for a quiet consideration of the inner life. Two examples of such criticism are offered, in both of which relational analysts are described as being too focused on social interaction and too little on the inner life. I offer my own version of the kinds of arguments about privacy and contemplation offered by Cooper, Corbett, and Seligman. I then make the case that all psychoanalytic theories come with risks of excess. Relational and interpersonal theories come with the risk of an overenthusiastic embrace of clinical interaction, whereas more intrapsychic theories carry the risk of attending too little to the impact on their patients of present-day relatedness—which is just as likely to have unconscious roots as the inner life.     

Effects of Hormone Replacement Therapy and Aging on Cognition: Evidence for Executive Dysfunction

ABSTRACT

The present study was designed to explore whether the frontal lobe hypothesis of cognitive aging may be extended to describe the cognitive effects associated with estrogen use in postmenopausal women. Postmenopausal estrogen-only users, estrogen + progesterone users, and non-users (60–80 years old), as well as young, regularly cycling women (18–30 years old) completed an item and source memory task. Since source memory is thought to rely more on executive processes than item memory, we hypothesized that aging and estrogen effects would be greater for source memory than for item memory. Neuropsychological tests explored whether the effects of aging and estrogen use were revealed on other tests of frontal lobe function. Results from the experimental task revealed greater aging and estrogen effects for source memory than for item memory, and neuropsychological results revealed aging and estrogen effects on a subset of tests of executive function. Women on estrogen + progesterone therapy did not outperform non-users, suggesting that the addition of progesterone to hormone therapy may mitigate the benefits induced by estrogen use alone. Overall, findings support the hypothesis that estrogen use may temper age-related cognitive decline by helping to maintain functions subserved by the frontal lobes.     

The Dynamic Relationship Between Accuracy and Bias in Social Perception Research

How do perceivers make accurate social judgments? A substantial amount of evidence suggests that perceivers' judgments are often quite accurate even when they do not have direct access to the truth, in part because they make judgments through biased processes. In the present article, we examine the dynamic relationship between bias and accuracy in social perception research. We outline how bias and accuracy are theoretically and empirically distinct processes and describe the importance (and difficulty) of defining and measuring both truth variables and bias variables in order to make empirical conclusions in accuracy research. Additionally, we examine how both bias variables (e.g., stereotypes, perceivers' own beliefs) and truth variables exert an influence on how perceivers make social judgments, as well as the extent to which judgments are accurate. Lastly, we provide steps that researchers can take in order to examine the relationship between bias and accuracy in their own research.

Support for religio‐political aggression among teenaged boys in Gaza: Part I: psychological findings

Politically aggressive militant groups usually rely on support from a larger community, although evidence suggests that only some members of that larger community support that aggression. A major subtype of political aggression is that associated with religious differences—or Religio‐Political Aggression (RPA). Little previous research has explored demographic or psychological factors that might distinguish supporters from non‐supporters of RPA. In an exploratory study, we investigated whether factors previously associated with aggression might correlate with support for RPA in the case of the Israeli/Palestinian conflict. During the second intifada, fifty‐two 14‐year‐old Palestinian boys in Gaza completed self‐report measures of life events, emotional status, and political attitudes. Teenaged boys who reported family members having been wounded or killed by the Israeli Defense Forces (IDF) expressed greater support for RPA (t(50)=?2.30, P=.026). In addition, boys who felt their group was treated unjustly reported greater support for RPA compared with those who did not (t(50)=?2.273, P=.027). Implications of these preliminary data are discussed. Aggr. Behav. 36:219–231, 2010. © 2010 Wiley‐Liss, Inc.     

Empathy is interpretation (and who ever said it wasn't?)

Whenever the subject is explicitly addressed, all analysts agree that empathic perception is an attitude one takes toward making observations, not a privileged means of perception. Furthermore, analysts seem to agree that observations made with an empathic intention are interpretations like any other observations. Empathy is not a conduit to the patient's inner life. But despite these points of consensus, it often seems to be implied in the psychoanalytic literature, usually unintentionally, that empathy is a privileged means of knowing another person. This undercurrent is sometimes present even in the work of theorists who simultaneously state their opposition to this very point of view. In this paper, after presenting an example from the literature of this kind of contradiction, I, basing my argument in hermeneutics, offer the view that all observation, inside and outside psychoanalysis, is interpretation. Then, turning to the three papers of the symposium individually, I take the perspective that in one way or another they all portray empathic perception as a privileged means of observation. These portrayals are examples of the unconscious politics of theory.     

Motivating Participation in National Park Service Curriculum-Based Education Programs

ABSTRACT

The authors explored barriers and motivations associated with high school and middle school classes’ participation in National Park educational programming through interviews with school administrators and surveys with teachers within the immediate vicinity of Great Smoky Mountains National Park. Although teachers commonly cited financial barriers to participation, administrators suggested that these were rarely insurmountable. Moreover, perceptions of such constraints did not help to predict teachers’ intentions to participate. Rather, teachers’ intentions to participate were most strongly predicted by their degree of comfort with relating park programs to the subject matter of their courses, their perceptions regarding whether or not the programs will enhance students’ academic achievement, and their expectations of whether the programs will expose students to environmental themes in an enjoyable manner. Results suggest the importance of classroom visits and direct communications with teachers emphasizing that programs are fun, relevant learning experiences that address academic requirements for multiple subjects and are relatively easy to incorporate into pre-existing curricula.     

Evidence for recovery of fear following immediate extinction in rats and humans

Fear responses can be eliminated through extinction, a procedure involving the presentation of fear-eliciting stimuli without aversive outcomes. Extinction is believed to be mediated by new inhibitory learning that acts to suppress fear expression without erasing the original memory trace. This hypothesis is supported mainly by behavioral data demonstrating that fear can recover following extinction. However, a recent report by Myers and coworkers suggests that extinction conducted immediately after fear learning may erase or prevent the consolidation of the fear memory trace. Since extinction is a major component of nearly all behavioral therapies for human fear disorders, this finding supports the notion that therapeutic intervention beginning very soon after a traumatic event will be more efficacious. Given the importance of this issue, and the controversy regarding immediate versus delayed therapeutic interventions, we examined two fear recovery phenomena in both rats and humans: spontaneous recovery (SR) and reinstatement. We found evidence for SR and reinstatement in both rats and humans even when extinction was conducted immediately after fear learning. Thus, our data do not support the hypothesis that immediate extinction erases the original memory trace, nor do they suggest that a close temporal proximity of therapeutic intervention to the traumatic event might be advantageous.     

Psychology's contributions to understanding and addressing global climate change

Global climate change poses one of the greatest challenges facing humanity in this century. This article, which introduces the American Psychologist special issue on global climate change, follows from the report of the American Psychological Association Task Force on the Interface Between Psychology and Global Climate Change. In this article, we place psychological dimensions of climate change within the broader context of human dimensions of climate change by addressing (a) human causes of, consequences of, and responses (adaptation and mitigation) to climate change and (b) the links between these aspects of climate change and cognitive, affective, motivational, interpersonal, and organizational responses and processes. Characteristics of psychology that cross content domains and that make the field well suited for providing an understanding of climate change and addressing its challenges are highlighted. We also consider ethical imperatives for psychologists' involvement and provide suggestions for ways to increase psychologists' contribution to the science of climate change.
