核心家庭父亲协同教养对青少年抑郁的影响:父子依恋和母子依恋的中介作用

基于家庭系统理论,采用父亲协同教养、父子依恋、母子依恋和抑郁量表,对河南省某中学初中一、二年级,高中一、二年级共计890名来自核心家庭的青少年进行调查,探索父亲协同教养各维度（团结、一致、冲突、贬低）与青少年抑郁之间的关系,以及父子依恋和母子依恋在二者关系中的中介作用。结果表明：（1）在控制其它维度作用的情况下,父亲协同教养中的团结和冲突对青少年抑郁具有显著的预测作用,一致和贬低对抑郁的预测作用不显著,表明团结、冲突对青少年抑郁具有显著的“独特效应”;（2）团结、一致、冲突、贬低性协同教养均对母子依恋具有显著影响,支持家庭系统中的“交叉效应”;团结、冲突对父子依恋具有显著影响,支持家庭系统中的“外溢效应”;（3）中介效应分析的结果表明,团结、一致、冲突对抑郁的直接效应不显著,母子依恋在团结与青少年抑郁、冲突与青少年抑郁的关系中起到完全中介作用,但父子依恋的中介作用不显著。本研究有助于增进对父亲协同教养的认知,对于指导家庭教育实践、促进青少年心理积极发展具有重要的意义。     

Le TASC200, une épreuve d’attention et de saillance visuelle : fidélité, validité et normes préliminaires

In the clinical setting, attention is classically assessed by tasks that do not take into account theoretically important aspects, such as the salience-based guidance of visual search. The aim of this study was to develop a paced paper-and-pencil task for clinical use based on strong theoretical accounts that would assess salience-based visual search and that would meet the psychometric requirements for the assessment of attention. Participants were required to search and cancel targets of varying visual saliences as quickly and as accurately as possible during a predefined short period of time. The targets were intermixed with distractors. In agreement with theories of salience-based visual search, the results showed that the most salient targets were detected more easily than less salient targets. The task exhibited a quite acceptable test-retest reliability, and two construct validity studies showed that different scores involve different processes. This new task fully complies with the major theories of salience-based guidance of attention during visual search. It also meets the requirements of a plausible clinical task since its psychometric qualities are quite good. Preliminary normative data (n = 863) are presented for clinical use.     

具身认知的“七宗罪”

近二十年来,具身认知已逐渐成为认知科学研究的主流趋势,其理论主张已经辐射到心理学、哲学、语言学、计算机科学等许多领域,研究成果运用范围逐渐扩大。诚然,具身认知在某种程度上弥补了“离身”认知的不足,但其在方法论和认识论方面的问题也日益突显,如循环论证,解释不充分,完全的二元对立,文化、社会、语言因素的忽视等。因此,当务之急是改进研究方法,摒弃先入之见,使其真正成为多角度、全方位、综合性研究。     

Visual load and variability of muscle activation: Effects on reactive driving of older adults

BackgroundThe functional significance of the increase in motor output variability with increased visual information processing in older adults remains unclear. Here, we test the hypothesis that increased visual information processing increases muscle activation variability in older adults and impairs their ability to react as fast and as precisely as young adults during a simulated reactive driving task.MethodsFourteen young and sixteen older adults performed a reactive driving simulation task that required responding to unexpected brake lights of the car ahead during a simple reaction time task (low visual information processing condition) and a choice reaction time task with “no go” trials condition (high visual information processing condition). We quantified the following: 1) reactive driving performance – combination of premotor response time, motor response time, and brake force error; 2) motor output variability – brake impulse variability; 3) muscle activation variability – variability in the tibialis anterior (TA) muscle activity.ResultsThe increase in information processing exacerbated the impaired reactive driving performance in older adults. The best predictor of this impairment was the increase in brake force error. The impaired reactive driving performance was related to brake impulse variability and variability in the TA activity.ConclusionsThis study provides novel evidence that increased information processing increases muscle activation variability in older adults with detrimental consequences to their ability to perform a simulated reactive driving task.     

Response-time evidence for mixed memory states in a sequential-presentation change-detection task

Response-time (RT) and choice-probability data were obtained in a rapid visual sequential-presentation change-detection task in which memory set size, study-test lag, and objective change probabilities were manipulated. False “change” judgments increased dramatically with increasing lag, consistent with the idea that study items with long lags were ejected from a discrete-slots buffer. Error RTs were nearly invariant with set size and lag, consistent with the idea that the errors were produced by a stimulus-independent guessing process. The patterns of error and RT data could not be explained in terms of encoding limitations, but were consistent with the hypothesis that long retention lags produced a zero-stimulus-information state that required guessing. Formal modeling of the change-detection RT and error data pointed toward a hybrid model of visual working memory. The hybrid model assumed mixed states involving a combination of memory and guessing, but with higher memory resolution for items with shorter retention lags. The work raises new questions concerning the nature of the memory representations that are produced across the closely related tasks of change detection and visual memory search.     

Maladaptive daydreaming: Evidence for an under-researched mental health disorder

This study explores the recently described phenomenon of Maladaptive Daydreaming (MD) and attempts to enhance the understanding of its features. It documents the experiences of 340 self-identified maladaptive daydreamers who spend excessive amounts of time engaged in mental fantasy worlds, in comparison to 107 controls. Our sample included a total of 447 individuals, aged 13–78, from 45 countries who responded to online announcements. Participants answered quantitative and qualitative questions about their daydreaming habits and completed seven questionnaires assessing mental health symptoms. Findings demonstrated that MD differs significantly from normative daydreaming in terms of quantity, content, experience, controllability, distress, and interference with life functioning. Results also demonstrated that Maladaptive Daydreamers endorsed significantly higher rates of attention deficit, obsessive compulsive and dissociation symptoms than controls. In sum, findings suggested that MD represents an under-acknowledged clinical phenomenon that causes distress, hinders life functioning and requires more scientific and clinical attention.     

Les métamorphoses du système de santé

The normative framework intervened in recent years to renovate and establish a coherent framework to the hospital system questions the bipartite division between private medicine and public medicine. The state supervision, consolidated by the Law of 26 January 2016 on the modernization of the health system, blurs the boundaries and involves renewing the qualification of our health system.     

Aging and performance on an everyday-based visual search task

Research on aging and visual search often requires older people to search computer screens for target letters or numbers. The aim of this experiment was to investigate age-related differences using an everyday-based visual search task in a large participant sample (n=261) aged 20-88 years. Our results show that: (1) old-old adults have more difficulty with triple conjunction searches with one highly distinctive feature compared to young-old and younger adults; (2) age-related declines in conjunction searches emerge in middle age then progress throughout older age; (3) age-related declines are evident in feature searches on target absent trials, as older people seem to exhaustively and serially search the whole display to determine a target's absence. Together, these findings suggest that declines emerge in middle age then progress throughout older age in feature integration, guided search, perceptual grouping and/or spreading suppression processes. Discussed are implications for enhancing everyday functioning throughout adulthood.     

Teaching children with autism to engage in peer-directed mands using a picture exchange communication system

We evaluated differential reinforcement of alternative behavior (DRA) plus prompting to increase peer-directed mands for preferred items using a picture exchange communication system (PECS). Two nonvocal individuals with autism participated. Independent mands with a peer increased with the implementation of DRA plus prompting for both participants. In addition, peers engaged in brief social interactions following the majority of mands for leisure items. These results suggest that teaching children to use PECS with peers may be one way to increase manding and social interactions in individuals with limited or no vocal repertoire.
