Conscious Postural Control During Standing on Compliant Surface by Older Adults

This study examined the real-time objective measurement of conscious postural control (“reinvestment”) in older adults when standing on a compliant surface using electroencephalogram (EEG) coherence. Twenty-nine older adults participated in the study and their Alpha2 T3-Fz and Alpha2 T4-Fz EEG coherence during standing at three different positions on foam including wide-base standing on foam (WBF), narrow-base standing on foam (NBF) and tandem standing on foam (TAF) were measured. Participants were also required to respond to a Visual Analog Scale (VAS) to determine their perceived task difficulty after each standing position. Three 2?×?3 (Groups[low reinvestor, high reinvestor]?×?Standing positions[WBF, NBF, TAF]) analysis of variance (ANOVA) with repeated measures were conducted to determine differences between high and low reinvestors in three standing positions (WBF, NBF, TAF) at the primary outcome measures. The main effects of standing positions at VAS and Alpah2 T3-Fz EEG coherence were discovered but without interaction. The results suggested that when standing task difficulty increased, older adults generally elevated their real-time conscious postural control together with perceived task difficulty. It implicates that Alpha2 T3-Fz EEG coherence can be considered as a real-time objective conscious postural control measurement during balance assessment and rehabilitation if further large-scale studies could find its discriminative power between high and low reinvestors.     

预警和呈现时间对错误再认和错误回忆的影响

采用DRM范式,通过两个实验探讨了学习阶段的预警和词表呈现时间对错误再认与错误回忆的影响异同以及其发生作用的可能条件.采用视觉-视觉通道的学习-测验模式,实验1使用再认测验,结果发现呈现时间对错误再认不存在影响,而预警提示有效地降低了错误再认;实验2使用回忆测验,依然没有发现呈现时间对错误回忆的影响效应,预警的效应也消失.以上结果表明:(1)预警对错误回忆的影响受到编码时呈现通道的影响,视觉编码条件下预警效果甚微,而错误再认则无此通道效应;(2)呈现时间的较大变化可同时促进激活与监测过程,错误记忆效应的大小是激活与监测双加工过程此消彼长的交互作用结果.     

Perceptions of accuracy and effort of decision strategies

A critical tenet of cost-benefit theories of decision strategy choice is that decision makers’ perceptions of accuracy and effort determine strategy selection. However, little research has been conducted on human perceptions of decision strategy accuracy and effort. Instead, researchers have substituted deductively derived inferences on strategy accuracy and effort for perceptions in interpreting decision processes. In this study, we used a survey to study perceptions of decision strategies. The results indicate that participants as a group understood the accuracy and effort dimensions of decision strategies. The participants’ perceptions of the accuracy and effort of various decision strategies largely agreed with researchers’ deductions. However, there was substantial variation across individuals in perceptions of various decision strategies and in the composition of efficient frontiers of decision strategies.

SEX DIFFERENCES IN PERSUASIBILITY FACTORS AMONG CHINESE1

Différences selon le sexe dans les facteurs de sensibilité à la persuasion chez des sujets chinois. — Plusieurs analyses factorielles distinctes ont été faites à partir des notes de sensibilité à la persuasion d'adolescents chinois, filles et garçons. Pour les garçons, trois facteurs émergent: le premier est relatif aux aux questions qui ne sont ni idéologiques, ni personnelles, le second aux questions idéologiques et le troisième, aux questions personnelles. Pour les filles, quatre facteurs ont pu être identifiés: L'un semble exprimer un certain ressentiment contre L'autorité masculine, le second est semblable au facteur idéologique trouvé chez les garçons; les deux derniers indiquent une sensibilité, L'un aux effets de priorité, L'autre, aux effets de récence. Les différences selon le sexe que L'on a constatées dans les facteurs, semblent être le reflet des différences dans les normes prescrites à L'un et L'autre sexe dans la culture chinoise traditionnelle.     

Predictors and Outcomes of Sudden Gains and Sudden Regressions in Cognitive Behavioral Therapy for Youth Anxiety

Sudden gains (SGs), referring to large, stable symptom improvement occurring between consecutive treatment sessions, have been associated with improved outcomes among adults with various psychological disorders. Little research exists on SGs or sudden symptom worsening (i.e., sudden regressions [SRs]) during treatment for youth disorders. The current study examined predictors and outcomes of SGs/SRs via multiple informants in youth anxiety treatment. Participants were 118 youth (age M = 11.6, SD = 2.5; 53.8% female) and their caregivers receiving a cognitive-behavioral therapy protocol for a principal anxiety disorder. Anxiety symptom severity was assessed weekly via the State-Trait Anxiety Inventory for Children–Trait–Child/Parent versions. SGs and SRs occurred in 45.8 and 31.3% of youth, respectively. SRs were more common among youth with comorbid mood or externalizing disorders, while SGs occurred more often among youth with greater pretreatment anxiety symptom severity. SGs were not associated with posttreatment outcomes, but SRs predicted significantly higher posttreatment internalizing symptoms based on child report (β = .23, p = .03) and externalizing symptoms based on child (β = .15, p = .04) and parent report (β = .16, p = .03), controlling for overall magnitude of symptom change. SRs among youth receiving cognitive-behavioral therapy for anxiety are associated with pretreatment clinical complexity and poorer posttreatment outcomes and may serve as a warning sign to clinicians of possible treatment failure.     

Attaching meaning to the number words: contributions of the object tracking and approximate number systems

Children's understanding of the quantities represented by number words (i.e., cardinality) is a surprisingly protracted but foundational step in their learning of formal mathematics. The development of cardinal knowledge is related to one or two core, inherent systems – the approximate number system (ANS) and the object tracking system (OTS) – but whether these systems act alone, in concert, or antagonistically is debated. Longitudinal assessments of 198 preschool children on OTS, ANS, and cardinality tasks enabled testing of two single‐mechanism (ANS‐only and OTS‐only) and two dual‐mechanism models, controlling for intelligence, executive functions, preliteracy skills, and demographic factors. Measures of both OTS and ANS predicted cardinal knowledge in concert early in the school year, inconsistent with single‐mechanism models. The ANS but not the OTS predicted cardinal knowledge later in the school year as well the acquisition of the cardinal principle, a critical shift in cardinal understanding. The results support a Merge model, whereby both systems initially contribute to children's early mapping of number words to cardinal value, but the role of the OTS diminishes over time while that of the ANS continues to support cardinal knowledge as children come to understand the counting principles.     

Rethinking procrastination: positive effects of "active" procrastination behavior on attitudes and performance

Researchers and practitioners have long regarded procrastination as a self-handicapping and dysfunctional behavior. In the present study, the authors proposed that not all procrastination behaviors either are harmful or lead to negative consequences. Specifically, the authors differentiated two types of procrastinators: passive procrastinators versus active procrastinators. Passive procrastinators are procrastinators in the traditional sense. They are paralyzed by their indecision to act and fail to complete tasks on time. In contrast, active procrastinators are a "positive" type of procrastinator. They prefer to work under pressure, and they make deliberate decisions to procrastinate. The present results showed that although active procrastinators procrastinate to the same degree as passive procrastinators, they are more similar to nonprocrastinators than to passive procrastinators in terms of purposive use of time, control of time, self-efficacy belief, coping styles, and outcomes including academic performance. The present findings offer a more sophisticated understanding of procrastination behavior and indicate a need to reevaluate its implications for outcomes of individuals.     

The cultural theory and model of suicide

A growing body of research has demonstrated important variations in the prevalence, nature, and correlates of suicide across ethnic and sexual minority groups. Despite these developments, existing clinical and research approaches to suicide assessment and prevention have not incorporated cultural variations in any systematic way. In addition, theoretical models of suicide have been largely devoid of cultural influence. The current report presents a comprehensive analysis of literature describing the relationship between cultural factors and suicide in three major ethnic groups (African Americans, Asian Americans, and Latinos) and LGBTQ¹ sexual minority groups. We utilized an inductive approach to synthesize this variegated body of research into four factors that account for 95% of existing culturally specific risk data: cultural sanctions, idioms of distress, minority stress, and social discord. These four cultural factors are then integrated into a theoretical framework: the Cultural Model of Suicide. Three theoretical principles emerge: (1) culture affects the types of stressors that lead to suicide; (2) cultural meanings associated with stressors and suicide affect the development of suicidal tendencies, one's threshold of tolerance for psychological pain, and subsequent suicidal acts; and (3) culture affects how suicidal thoughts, intent, plans, and attempts are expressed. The Cultural Model of Suicide provides an empirically guided cohesive approach that can inform culturally competent suicide assessment and prevention efforts in future research and clinical practice. Including both ethnic and sexual minorities in our investigations ensures advancement along a multiple identities perspective.
