An adult model of preschool children’s speech memory

In previous work, it has been demonstrated that phonetic similarity among the items in a spoken list interferes with recall much more in school-aged children than in preschool children. The basis of this developmental change, however, is unclear. In the present study we examined the possibility that a developmental increase in the use of covert verbal rehearsal accounts for the change in the effects of phonetic similarity. Adults who recalled lists of spoken words during articulatory suppression tasks that blocked covert rehearsal were found to display patterns of recall that resembled those ordinarily found in 5-year-old children. The specific aspects of rehearsal responsible for these effects also were investigated.     

Drawing on the experiences of alternative decision-makers: Can we preserve the jury in complex civil litigation?

Many have questioned the wisdom of using traditional juries to decide cases involving complex scientific and technical evidence. Alternative decision-makers that have been proposed include: judges; expert arbitrators; special juries composed of people who possess either a minimum level of higher education or knowledge especially relevant to the issues in the particular trial; and panels of experts in the particular field, acting as either a jury or a non-jury tribunal. These alternatives differ from the traditional jury not only in their composition but also, to varying degrees, in terms of the resources available to them and the procedures under which they operate. In this article, we explore the advantages that these alternative decision-makers have over juries and discuss how the same resources and procedures enjoyed by the alternatives could be made available to and enhance the abilities of the traditional jury in cases involving complex evidence.     

Memory phenomena in the law

Memory issues arise in the law in many different ways. At the most fundamental level, assumptions about memory are inherent in both substantive laws and procedural rules that govern the operation of the legal system. For example, the rules and procedures used to govern the conduct of jury trials reflect a great deal of faith in jurors' ability to understand and retain information over long periods of time, often with much intervening information. Memory issues also arise in the context of individual cases. For example, the ability of an attorney to satisfactorily prosecute or defend a case on behalf of a client often relies largely upon the completeness and accuracy of the memory of the client and other witnesses. This paper discusses examples of memory issues in the law and describes how applied research on these issues can be used to inform basic memory theory, particularly with respect to the relationship between emotion and memory.     

The Living Body as the Origin of Culture: What the Shift in Husserl’s Notion of “Expression” Tells us About Cultural Objects

Husserl’s philosophy of culture relies upon a person’s body being expressive of the person’s spirit, but Husserl’s analysis of expression in Logical Investigations is inadequate to explain this bodily expressiveness. This paper explains how Husserl’s use of “expression” shifts from LI to Ideas II and argues that this shift is explained by Husserl’s increased understanding of the pervasiveness of sense in subjective life and his increased appreciation for the unity of the person. I show how these two developments allow Husserl to better describe the bodily expressiveness that is the source of culture. Husserl’s account of culture is thoroughly intentionalistic, but it does not emphasize thought at the expense of embodiment. Culture originates not in an abstract subjectivity, but by persons’ expressing themselves physically in the world. By seeing how Husserl develops his mature position on bodily expressiveness, we can better appreciate the meaningfulness and the bodily concreteness of cultural objects.

Putting feelings into words: affect labeling disrupts amygdala activity in response to affective stimuli

Putting feelings into words (affect labeling) has long been thought to help manage negative emotional experiences; however, the mechanisms by which affect labeling produces this benefit remain largely unknown. Recent neuroimaging studies suggest a possible neurocognitive pathway for this process, but methodological limitations of previous studies have prevented strong inferences from being drawn. A functional magnetic resonance imaging study of affect labeling was conducted to remedy these limitations. The results indicated that affect labeling, relative to other forms of encoding, diminished the response of the amygdala and other limbic regions to negative emotional images. Additionally, affect labeling produced increased activity in a single brain region, right ventrolateral prefrontal cortex (RVLPFC). Finally, RVLPFC and amygdala activity during affect labeling were inversely correlated, a relationship that was mediated by activity in medial prefrontal cortex (MPFC). These results suggest that affect labeling may diminish emotional reactivity along a pathway from RVLPFC to MPFC to the amygdala.     

An Empirical Test of Target Congruence Theory on Intimate Partner Violence

The purpose of the current study was to test target congruence theory as an explanation of intimate partner violence. Specifically, the effects of target vulnerability, target gratifiability, and target antagonism were examined for their effects on intimate partner violence against women. To do this, data collected in 2009 from a sample of 1,452 respondents to the Canadian General Social Survey were analyzed using binary logistic regression. Overall, the results suggest support for the theory, particularly for the concept of target gratifiability, and for target vulnerability to a lesser degree. As the first study to apply the theory to intimate partner violence, findings suggest that target congruence may be a valuable theoretical perspective in understanding victimization risk.     

Situation selection across adulthood: the role of arousal

In this study, we investigated age differences in situation selection to understand the role stimulus arousal plays in motivating age differences in this type of emotion regulation. Participants freely selected from a set of affective videos using information about the valence and arousal of each stimulus. There were age differences both in the valence and arousal of selected stimuli. Older adults selected more neutral and low-arousal stimuli while younger adults selected more negative and high-arousal stimuli. We consider these results in light of recent theoretical models and conclude that studies of age differences in emotion regulation must consider both valence and arousal.     

Effects of body mass index and education on verbal and nonverbal memory

We previously reported that higher education protects against executive dysfunction related to higher body mass index (BMI) in younger, but not older, adults. We now extend the previous analyses to verbal and nonverbal memory. Fifty-nine healthy, dementia-free community-dwelling adults ranging in age from 18 to 81 years completed the Hopkins Verbal Learning Test – Revised (HVLT-R) and the Brief Visuospatial Memory Test – Revised (BVMT-R). Self-reported years of education served as a proxy for cognitive reserve. We found that more highly educated individuals maintained their BVMT-R immediate recall performance across the range of BMI, but in less educated individuals, higher BMI was associated with worse performance. Our findings suggest that education may play a protective role against BMI-related nonverbal learning deficits, similar to previous reports for verbal memory and executive functioning. Results highlight the importance of considering educational background when determining the risk for BMI-related cognitive impairment in clinical settings.     

Serotonin enhances the impact of health information on food choice

Serotonin has been implicated in promoting self-control, regulation of hunger and physiological homeostasis, and regulation of caloric intake. However, it remains unclear whether the effects of serotonin on caloric intake reflect purely homeostatic mechanisms, or whether serotonin also modulates cognitive processes involved in dietary decision making. We investigated the effects of an acute dose of the serotonin reuptake inhibitor citalopram on choices between food items that differed along taste and health attributes, compared with placebo and the noradrenaline reuptake inhibitor atomoxetine. Twenty-seven participants attended three sessions and received single doses of atomoxetine, citalopram, and placebo in a double-blind randomised cross-over design. Relative to placebo, citalopram increased choices of more healthy foods over less healthy foods. Citalopram also increased the emphasis on health considerations in decisions. Atomoxetine did not affect decision making relative to placebo. The results support the hypothesis that serotonin may influence food choice by enhancing a focus on long-term goals. The findings are relevant for understanding decisions about food consumption and also for treating health conditions such as eating disorders and obesity.
