The Caregivers' Attachment and Relationship Education Class: A New and Promising Group Therapy for Caregivers of Individuals with Parkinson's Disease

The authors examined whether a newly developed group therapy, based on principles of attachment theory and emotionally focused couples therapy, can potentially address the unique mental health and relationship difficulties in caregivers of individuals with Parkinson's disease. A comprehensive outreach effort, involving a review of 251 military veterans' medical records, yielded enrollment of seven spousal caregivers in the group therapy. At 1-month follow-up, caregivers who initially reported mild or greater levels of caregiver burden demonstrated statistically reliable declines in psychological distress, relationship distress, or both. Posttreatment surveys indicated positive perceptions in overall helpfulness of treatment goals, as well as positive changes in insight (e.g., greater understanding of the patient's attachment needs) and behaviors (e.g., greater social contact and self-care of the caregiver). Results are considered in the context of inadequate access to treatment for caregivers of spouses with Parkinson's disease or other major medical issues.

The Trait Anxiety Scale for Children: A validation study for European Portuguese children and adolescents

The State-Trait Anxiety Inventory for Children is a self-report instrument inspired on the State-Trait theory extended by Spielberger that measures a momentary state of anxiety (state) and a stable tendency to experience anxiety (trait). This study presents an exploratory adaptation of the Trait Scale and provides its psychometric properties for European Portuguese children and adolescents. The influence of sex and age were also explored. Our sample, composed of 402 participants aged 8–14 years, revealed a mean anxiety value of 28.37 (SD = 5.99). As expected, females revealed higher levels of anxiety than boys. Higher anxiety was obtained in our youngest group as compared to the oldest group. The exploratory factor analysis led to retaining only 16-items that presented acceptable adjustment to a one-factorial solution. Good indexes were obtained in the confirmatory analysis. The results also revealed good internal consistency and good test-retest reliability. Our results provide initial evidence that this scale is adequate to measure trait-anxiety in European Portuguese young people.     

Simultaneous motor demands affect decision making under objective risk

Previous studies on factors influencing decision making focused on the effects of additional cognitive load, stress, psychological disorders, and the process of aging. The potential effects of simultaneously performing motor demands have been neglected, so far. However, previous motor / cognitive dual-task studies provide evidence for both negative as well as facilitating effects of simultaneously performing cognitive and motor tasks. The study at hand, aimed to investigate the effects of decision making under objective risk while performing additional motor demands. Seventy-two participants ranging from 18 to 30 years performed the Game of Dice Task either while sitting or while standing on one leg. Participants were asked to put similar effort on the decision task and the motor demand. The results revealed a significant main effect for “choice”, as well as a significant interaction of “choice”?×?“group”. Participants standing on one leg more frequently selected the most disadvantageous choice (one single number), whereas the “sitting group” most often selected the advantageous combination of four numbers. The findings are discussed under the aspects of executive functions, working memory, stress, somatic markers and the dual-process theory.     

A Comprehensive Decision Approach for Rubber Tree Planting Management in Africa

The main objective of this study is to settle a rigorous field of decision analysis for rubber tree clones selection. Nowadays, there does not exist any process based upon a rigorous method to select the best clone to be plant in order to get the highest return on investment. The only known selection method is to use the experience of different protagonists acting in the plantation. So, we need a tool that takes into account very important criteria in order to achieve the main objective. This goal is achieved by using multicriterion analysis methods to the clone selection. The ranking procedure uses Elimination and Choice Expressing the Reality (ELECTRE III). For each criterion, indifference and preference thresholds are determined after establishing the relative importance of each criterion including rubber tapping, cumulative production during 15 years, cumulative production between 15 and 25 years, wind resistance, disease resistance, physiological resistance, grafting and quality of the rubber.

Anticipatory attention during the sleep onset period

To examine whether anticipatory attention or expectancy is a cognitive process that is automatic or requires conscious control, we employed a paired-stimulus event-related potential (ERP) paradigm during the transition to sleep. The slow negative ERP wave observed between two successive stimuli, the Contingent Negative Variation (CNV), reflects attention and expectancy to the second stimulus. Thirteen good sleepers were instructed to respond to the second stimulus in a pair during waking sessions. In a non-response paradigm modified for sleep, participants then fell asleep while tones played. As expected, N1 decreased and P2 increased in amplitude systematically with the loss of consciousness at sleep onset; the CNV was increasingly more positive. Sleep onset latency was correlated with the amplitude of the CNV. The systematic attenuation of the CNV waveform at sleep onset and its absence in sleep indicates that anticipatory attention requires endogenous conscious control.     

Experience of agency and sense of responsibility

The experience of agency refers to the feeling that we control our own actions, and through them the outside world. In many contexts, sense of agency has strong implications for moral responsibility. For example, a sense of agency may allow people to choose between right and wrong actions, either immediately, or on subsequent occasions through learning about the moral consequences of their actions. In this study we investigate the relation between the experience of operant action, and responsibility for action outcomes using the intentional binding effect (Haggard, Clark, & Kalogeras, 2002) as an implicit, quantitative measure related to sense of agency. We studied the time at which people perceived simple manual actions and their effects, when these actions were embedded in scenarios where their actions had unpredictable consequences that could be either moral or merely economic. We found an enhanced binding of effects back towards the actions that caused them, implying an enhanced sense of agency, in moral compared to non-moral contexts. We also found stronger binding for effects with severely negative, compared to moderately negative, values. A tight temporal association between action and effect may be a low-level phenomenal marker of the sense of responsibility.     

Another dragon in the kitchen: Psychological experiences of hepatitis C treatment among HIV‐hepatitis C co‐infected gay men

Background: Increasing numbers of HIV‐infected gay men acquire hepatitis C virus (HCV) co‐infection, which causes serious medical consequences. Treatment for HCV is associated with many severe side effects, in some cases psychological, and many patients subsequently fail to adhere, even when psychological services are utilised, to improve treatment adherence. Objective: This qualitative study aimed to explore the experiences of HIV‐infected gay men undergoing treatment for HCV in order to inform psychological services to better meet specific treatment needs of this population. Methods: Thirteen HIV‐infected gay men who had undergone HCV treatment were interviewed and a qualitative analysis was conducted. Participants described HCV and its treatments in the context of their relationships and lifestyles. Findings: Four domains emerged: HCV diagnosis and treatment; HCV treatment education; change in sense of self; and sexual risk‐taking. Adhering to treatment was a significant challenge for all participants and emerged across all domains. Discussion: Psychological services for this population of co‐infected gay men should assist this clinical population not only with adherence to hepatitis C treatment but should also be available at an earlier stage in the process to help patients make informed choices about whether or not to begin a course of treatment. Assessing factors such as coping strategies, treatment readiness and knowledge, self‐awareness, and level of risk‐taking, can guide clinicians in tailoring treatment and adherence planning for HIV/HCV‐co‐infected gay men.     

消费决策中羊群行为的心理机制

羊群行为是消费市场上的一种典型现象,它是指在不确定情境中,消费者模仿他人进行消费决策的行为。本研究通过模拟消费情境对消费者羊群行为的心理机制进行研究。研究1通过操纵观点的强弱研究消费者的信息加工方式。结果发现,消费者的羊群行为是消费者采用一致性启发式或能力启发式的结果。研究2进一步通过操纵群体内部的一致性程度考察两种启发式的作用条件。结果表明,在群体内部一致性程度高的情况下,消费者倾向于采用一致性启发式,与大众决策保持一致;在群体内部一致性低的情况下,消费者倾向于采用能力启发式,与专家的决策保持一致。
