3～4岁幼儿认知灵活性实验研究

采用维度变化卡片分类测验,对3~4岁儿童进行认知灵活性测试。根据测验结果发现在标准版本与全部变化版本间存在十分显著差异,在部分变化版与全部变化版本间同样存在十分显著差异,而在标准版本与部分变化版本间差异不显著。性别之间在后转换阶段成绩存在显著差异。年龄之间在前转换阶段成绩存在显著差异,这就表明3岁幼儿当需要在两套不相容的规则之间进行灵活的转换时遇到了困难,即前转换阶段激活了的规则保持在后转换阶段中。超过3岁到4岁间的幼儿比低于3岁或刚3岁的幼儿分类成绩要好。     

Initial development and validity evidence for the processes of change in Psychological Skills Training Questionnaire

ObjectivesThe purpose of this study was to create and provide validity evidence for the Processes of Change in Psychological Skills Training Questionnaire (PCPSTQ).DesignThe current study used a cross-sectional research design.MethodsFive hundred fifty nine NCAA Division I, professional, and Olympic level athletes participated in the current study. To create the PCPSTQ, an initial pool of 114 items was generated by the research team. After a content validity process, 65 items were retained for analysis. Exploratory structural equation modeling was used as an analytic strategy to identify the most appropriate factor structure for the PCPSTQ. Decisions about the most appropriate model were made using multiple fit indices. To examine the construct validity of the PCPSTQ, a series of one-way ANOVAs were conducted to examine differences in processes of change use across stage of change.ResultsIn the current study, validity evidence provided support for a 7-factor process of change measure (χ² = 325.84, p < .001; Comparative Fit Index = .971; Tucker Lewis Index = .945; Root Mean Square Error of Approximation = .037; Standard Root Mean Square Residual = .020). Results also supported the construct validity of the scale as a significant difference in process of change use across stage of change was reported for all seven processes.ConclusionsResults of the current study support the factor structure and construct validity of the PCPSTQ. It appears that the processes of behavior change reported across multiple behavior change domains might also be viable for sport psychology professionals.     

Goals and plans for Big Five personality trait change in young adults

Four studies were conducted on young adults’ goals and plans to change personality traits. In Study 1, a new trait change goal assessment tool, the BF-TGI, found Neuroticism to be the most frequently cited trait for a change goal. In Study 2, data was gathered from the UK, Iran and China. Iran showed a higher prevalence of normative change goals than the UK and China. Study 3 investigated plans to change traits. Extraversion and Conscientiousness plans were more specific than for the other traits. Study 4 investigated whether goals and plans to change predict change over 12 months, and found that goals and plans to change Conscientiousness and Neuroticism predicted change in the opposite direction to the goal.     

Blind Speakers Show Language‐Specific Patterns in Co‐Speech Gesture but Not Silent Gesture

Sighted speakers of different languages vary systematically in how they package and order components of a motion event in speech. These differences influence how semantic elements are organized in gesture, but only when those gestures are produced with speech (co‐speech gesture), not without speech (silent gesture). We ask whether the cross‐linguistic similarity in silent gesture is driven by the visuospatial structure of the event. We compared 40 congenitally blind adult native speakers of English or Turkish (20/language) to 80 sighted adult speakers (40/language; half with, half without blindfolds) as they described three‐dimensional motion scenes. We found an effect of language on co‐speech gesture, not on silent gesture—blind speakers of both languages organized their silent gestures as sighted speakers do. Humans may have a natural semantic organization that they impose on events when conveying them in gesture without language—an organization that relies on neither visuospatial cues nor language structure.     

Understanding organizational resilience in elite sport: An exploration of psychosocial processes

ObjectivesAlthough organizational resilience research has identified the characteristics of elite sport organizations that successfully deal with significant change, further research is needed to understand how they function. The objective of this study was to explore the psychosocial processes underpinning organizational resilience in elite sport.Design and methodUsing interviews supplemented by timelines compiled from documentary analysis of public online sources, data was gathered during 43 interviews with 22 participants from 10 elite sport organizations across an 8-month period. Participant roles included chief executive officers (n = 5), directors (n = 7), board members (n = 2), middle managers (n = 4), support staff (n = 2), head coach (n = 1), and senior athlete (n = 1). Reflexive thematic analysis of the data was conducted from a critical realist standpoint.ResultsThe data analysis yielded two core processes of sensing (internal and external mechanisms, diversity of perspectives, evaluating and monitoring) and adapting (mirroring current resource availability, open and frequent communication, acute versus chronic change), and two supporting processes of strengthening resources (quality and quantity of human and financial resources, relationships as source of additional resources) and shielding from risk (internal risk mitigation, external influencing). These data were interpreted to indicate that these processes are not sequential, or temporally distinct, but instead cumulatively contribute towards an organization’s resilience capability.ConclusionsAs the first empirical investigation exploring the psychosocial processes underpinning organizational resilience in elite sport, the results provide a unique framework and practical implications to help those working in and with elite sport organizations successfully navigate uncertainty and change.     

Resources masquerading as slots: Flexible allocation of visual working memory

Whether the capacity of visual working memory is better characterized by an item-based or a resource-based account continues to be keenly debated. Here, we propose that visual working memory is a flexible resource that is sometimes deployed in a slot-like manner. We develop a computational model that can either encode all items in a memory set, or encode only a subset of those items. A fixed-capacity mnemonic resource is divided among the items in memory. When fewer items are encoded, they are each remembered with higher fidelity, but at the cost of having to rely on an explicit guessing process when probed about an item that is not in memory. We use the new model to test the prediction that participants will more often encode the entire set of items when the demands on memory are predictable.     

Sleep loss and change detection in driving scenes

Driver sleepiness is a significant road safety problem. Sleep-related crashes occur on both urban and rural roads, yet to date driver-sleepiness research has focused on understanding impairment in rural and motorway driving. The ability to detect changes is an attention and awareness skill vital for everyday safe driving. Previous research has demonstrated that person states, such as age or motivation, influence susceptibility to change blindness (i.e., failure or delay in detecting changes). The current work considers whether sleepiness increases the likelihood of change blindness within urban and rural driving contexts. Twenty fully-licenced drivers completed a change detection ‘flicker’ task twice in a counterbalanced design: once following a normal night of sleep (7–8 h) and once following sleep restriction (5 h). Change detection accuracy and response time were recorded while eye movements were continuously tracked. Accuracy was not significantly affected by sleep loss; however, following sleep loss there was some evidence of slowed change detection responses to urban images, but faster responses for rural images. Visual scanning across the images remained consistent between sleep conditions, resulting in no difference in the probability of fixating on the change target. Overall, the results suggest that sleep loss has minimal impact on change detection accuracy and visual scanning for changes in driving scenes. However, a subtle difference in response time to change detection between urban and rural images indicates that change blindness may have implications for sleep-related crashes in more visually complex urban environments. Further research is needed to confirm this finding.     

A Trajectory Approach to Causality

In this paper we propose a new approach to address the ramification problem in common-sense reasoning about action and change. We contrast the methods of McCain and Turner, Thielscher and Sandewall and, based on some of the limitations they encounter, we introduce a trajectory-based approach which keeps a history of the states through which a system evolves to characterise its dynamical state. We furnish an underlying state-transition semantics and a logic that admits an expressive, dynamical account of some typical scenarios which encounter modelling difficulties in the other approaches mentioned.

When less is heard than meets the ear: Change deafness in a telephone conversation

During a conversation, we hear the sound of the talker as well as the intended message. Traditional models of speech perception posit that acoustic details of a talker's voice are not encoded with the message whereas more recent models propose that talker identity is automatically encoded. When shadowing speech, listeners often fail to detect a change in talker identity. The present study was designed to investigate whether talker changes would be detected when listeners are actively engaged in a normal conversation, and visual information about the speaker is absent. Participants were called on the phone, and during the conversation the experimenter was surreptitiously replaced by another talker. Participants rarely noticed the change. However, when explicitly monitoring for a change, detection increased. Voice memory tests suggested that participants remembered only coarse information about both voices, rather than fine details. This suggests that although listeners are capable of change detection, voice information is not continuously monitored at a fine-grain level of acoustic representation during natural conversation and is not automatically encoded. Conversational expectations may shape the way we direct attention to voice characteristics and perceive differences in voice.
