Hippocampal theta (3-8Hz) activity during classical eyeblink conditioning in rabbits

In 1978, Berry and Thompson showed that the amount of theta (3–8 Hz) activity in the spontaneous hippocampal EEG predicted learning rate in subsequent eyeblink conditioning in rabbits. More recently, the absence of theta activity during the training trial has been shown to have a detrimental effect on learning rate. Here, we aimed to further explore the relationship between theta activity and classical eyeblink conditioning by determining how the relative power of hippocampal theta activity [theta/(theta + delta) ratio] changes during both unpaired control and paired training phases. We found that animals with a higher hippocampal theta ratio immediately before conditioning learned faster and also that in these animals the theta ratio was higher throughout both experimental phases. In fact, while the hippocampal theta ratio remained stable in the fast learners as a function of training, it decreased in the slow learners already during unpaired training. In addition, the presence of hippocampal theta activity enhanced the hippocampal model of the conditioned response (CR) and seemed to be beneficial for CR performance in terms of peak latency during conditioning, but did not have any effect when the animals showed asymptotic learning. Together with earlier findings, these results imply that the behavioral state in which hippocampal theta activity is absent is detrimental for learning, and that the behavioral state in which hippocampal theta activity dominates is beneficial for learning, at least before a well-learned state is achieved.     

Dissociating cue-related and task-related processes in task inhibition: evidence from using a 2:1 cue-to-task mapping.

Performance of task sequences is assumed to rely on activation and inhibition of tasks. An empirical marker of task inhibition is the so-called n-2 repetition cost, which is assessed by comparing performance in trial n-2 task repetitions (i.e., ABA) with that in n-2 task switches (i.e., CBA). Current theoretical accounts assume that inhibition acts on the level of task representations (i.e., task sets). However, another potential target of task inhibition could be the representation of the task cue. To decide between these two alternatives, the authors used a 2:1 cue-to-task mapping design. They found significant n-2 task repetition costs both with n-2 cue repetitions and n-2 cue switches. These costs were about equal (Experiment 1), and this data pattern was found for both short and long cuing intervals (Experiment 2). Together, the data suggest that task inhibition acts on task sets and not on cue representations.     

Maternal Antisocial Behavior, Parenting Practices, and Behavior Problems in Boys at Risk for Antisocial Behavior

We investigated the independent contributions of maternal history of antisocial behavior and parenting practices to the worsening course of sons' behavior problems in a sample of young urban boys at risk for antisocial behavior. Mothers reported on boys' behavior problems at baseline and one year later, as well as on their own history of antisocial behavior before and after age 15, and of lifetime depression and substance use disorders (provisional DSM-III-R diagnoses). Baseline reports of parenting practices were obtained. Lower involvement, lower monitoring, and higher levels of parent–child conflict and maternal Conduct Disorder (CD) before age 15 contributed to the worsening of boys' behavior problems one year later; mothers' symptoms of Antisocial Personality Disorder after age 15 did not. Mothers' lifetime history of Major Depression and Substance Use Disorder did not add to the worsening of boys' behavior problems after accounting for these other factors. Although maternal CD contributed directly to the worsening of boys' behavior problems, the effect of parenting was more substantial. We discuss clinical implications for prevention and treatment of children's antisocial behavior, and intergenerational implications of girls' early antisocial behavior.     

Acquiring a cognitive skill with a new repeating version of the Tower of London task.

A computerized version of the Tower of London task was used to investigate cognitive skill learning. Thirty-six healthy volunteers were assigned to either a random condition (nonrecurring problems), or to a sequence condition in which, unbeknownst to the subjects, a repeating sequence of three problems was presented. Indices of execution, planning, and total time, as well as number of moves performed, were used to measure behavioural change. Subjects' performance improved in both conditions across blocks of practice. A distinct learning effect related to the repeating sequence was also observed. This suggests that a specific skill that reflects procedural learning of the strategies, rules, and procedures pertaining to repeating problems can develop over and above a more general skill at solving cognitive planning problems with practice.     

Cultivating the Senses and Giving in to the Sacred: Notes on Body and Experience among Pentecostal Women in Salvador,Brazil

The article deals with the religious experience of poor Pentecostal women from the city of Salvador, Northeast Brazil. In centering the discussion of this experience on bodily engagement in place—and on the body's attunement to place—this article seeks to capture the social and existential dimensions of the sensibilities which women develop as members of the religious community and thus to address the question of how the sense experiences, which are awakened and cultivated in this religious setting, help shape embodied forms of attention to oneself, to others, and to context. We contend that concrete embodied experience of divine power fostered in ritual favors training attention to context in search of signs of divine presence and helps give shape to a disposition which extends, to other people and places, the power that flows from Pentecostal women's bodies.     

Psychosocial predictors of chronic Post-Traumatic Stress Disorder in Sri Lankan tsunami survivors

This study aimed to determine whether psychological factors associated with Post-Traumatic Stress Disorder (PTSD) identified in Western samples generalize to low Social-Economical-Status (SES) populations in an underdeveloped Asian country. The study included 113 survivors of the 2004-tsunami on the south coast of Sri Lanka, recruited from 4 preschools and 10 villages for displaced persons. With logistic regressions the relations between interview-based PTSD diagnosis and psychological factors were assessed, controlling for putative confounders. Fifteen months post-trauma the prevalence of PTSD was 52.2%. Multivariate analyses indicated that negative interpretation of tsunami-memories was significantly (P < 0.005) related to PTSD. Of the putative confounders, gender and (non-replaced) lost work equipment were related to current PTSD (P < 0.05). The results indicate that the relation between negative interpretation of trauma memories and PTSD is quite universal, suggesting that interventions focusing on this factor may be important in treatment of tsunami survivors who are suffering from chronic PTSD.     

Individuals high in neuroticism are not more reactive to adverse events

Numerous studies have related neuroticism to negative emotional outcomes of adverse life events, including post-traumatic stress disorder (PTSD) symptoms. However, the nature of the relationship between neuroticism and post-trauma symptoms is unclear. The purpose of this study was to prospectively examine whether individuals high in neuroticism, relative to low neuroticism individuals, show a larger increase in symptoms after an adverse event. A sample of infantry troops completed questionnaires before deployment to Iraq (n = 214) and about five months (n = 170; 76%) thereafter. The findings showed that, after controlling for an indicator of trauma severity, (a) higher neuroticism individuals reported more PTSD symptoms, depression symptoms, and somatic problems after negative events, and (b) these relationships disappeared after controlling for pre-trauma symptoms. There were no significant differences between individuals high and low in neuroticism in the increase in symptoms from pre to post-trauma. This suggests that individuals high in neuroticism are not more reactive to adverse events.

Treatment of urethral catheter dependence: A case study of intervention in the interdisciplinary geriatric setting

This case report describes the assessment and treatment of a 69-year-old male medical patient with urethral catheter dependence. Assessment revealed an anxiety/phobic component to the dependence and hypothesized detrusor muscle deconditioning. Retraining of the bladder and desensitization to the anxiety-provoking situation were achieved by exposure to decatheterization in the context of a supportive adult day health care setting. Interdisciplinary collaboration between nursing and psychology were associated with successful functional, social, and psychological outcomes.A psychology intern at the Portland VA Medical Center at the time the study was conducted.
