Children with developmental coordination disorder (DCD) can adapt to perceptible and subliminal rhythm changes but are more variable

Children with DCD demonstrate impairments in bimanual finger tapping during self-paced tapping and tapping in synchrony to different frequencies. In this study, we investigated the ability of children with DCD to adapt motorically to perceptible or subliminal changes of the auditory stimuli without a change in frequency, and compared their performance to typically developing controls (TDC). Nineteen children with DCD between ages 6–11 years (mean age ± SD = 114 ± 21 months) and 17 TDC (mean age ± SD = 113 ± 21 months) participated in this study. Auditory perceptual threshold was established. Children initially tapped bimanually to an antiphase beat and then to either a perceptible change in rhythm or to gradual subliminal changes in rhythm. Children with DCD were able to perceive changes in rhythm similar to TDC. They were also able to adapt to both perceptible and subliminal changes in rhythms similar to their age- and gender- matched TDC. However, these children were significantly more variable compared with TDC in all phasing conditions. The results suggest that the performance impairments in bilateral tapping are not a result of poor conscious or sub-conscious perception of the auditory cue. The increased motor variability may be associated with cerebellar dysfunction but further behavioral and neurophysiological studies are needed.     

Developmental stages,Piagetian stages in particular: A critical review

Developmental stages in general and Piaget's stages in particular have given rise to considerable controversy. Much of this controversy revolves around the responses that have been given to the following five central questions: (1) Do developmental stages exist? (2) If they exist, where are they? (3) What features define a developmental sequence as a sequence of developmental stages? (4) What psychological processes underlie developmental change? (5) Should we abandon the concept of developmental stages? The main goal of this paper is to present a critical review of such responses, while arguing for a strong conception of development and a “non-received” view of Piaget's theory. After an introduction section, we elaborate on each of the five questions. Finally, we present several reasons why this paper often appeals to Piaget's theory, and why his theory has been greatly misunderstood.     

Cultural norms and cultural agents in buyer–seller negotiation processes and outcomes

Although a good number of studies have significantly investigated the role of culture in buyer–seller negotiation processes and outcomes, fewer studies have investigated the role of individual negotiators and organizations in shaping the cultural norms that affect negotiation processes and outcomes. Through a multi-case study of buyer–seller negotiations in five organizations that are illustrative of the informal economy of Nigeria, the study unpacks the role of individuals and organizations in shaping the cultural norms that affect the scope and outcomes of negotiation in an emerging market economy. We find that buyers and sellers play the role of inhabiting cultural norms which in turn narrow the scope of the negotiation to price considerations. On the other hand, the templates used by organizations to execute selling activities either maintain or deter the cultural norms that influence negotiation outcomes. Insights from the study extend the literatures on institutional work, culture and negotiation, sales negotiation in emerging markets.     

认知老化对于老年人决策过程的影响:动机的调节作用

有关老化和决策制定的研究并没有发现一致的年龄差异。从决策过程的角度,论述了老化对于决策制定的多层面影响。从认知层面来讲,流体认知能力的衰减会使老年人在决策制定前搜索更少的信息,使用非补偿性策略,基于属性进行信息搜索和比较;晶体认知能力的相对保持则在一定情况下弥补了这种消极影响;从动机层面来讲,关注情绪管理目标的老年人会倾向于寻求更多积极的信息,为了避免权衡诱发的消极情绪而更多地使用非补偿性策略。动机对于认知老化的消极影响有调节作用。具体来说,社会情绪选择理论和选择性投入假设认为,当决策任务符合老年人的社会目标,即情绪管理目标时,能够激活老年人投入认知资源的动机,从而缓解认知资源的衰减对于老年人决策表现的消极影响。未来的研究需要通过实验设计进一步探索动机与认知的交互作用,将多种过程追踪技术结合起来,明晰动机和认知能力在老年人决策制定中的作用。另外考虑到在社会目标方面的年龄差异,对于老年人决策质量的衡量应该更加注重主观决策质量。     

Applying processing trees in social psychology

Processing tree models offer a powerful research framework by which the contributions of cognitive processes to a task can be separated and quantified. The present article reviews a number of applications of processing tree models in the domain of social psychology in order to illustrate the steps to be taken in developing and validating a given model and applying it to the measurement and comparison of processes across experimental and quasi-experimental conditions. Process dissociation models are discussed as special cases of processing tree models. Crucial assumptions of processing tree models are considered and methods to overcome violations of such assumptions are reviewed. In addition to the application of processing tree models for the analysis of social and cognitive processes, their value is also discussed for the elicitation of truthful responses to socially sensitive questions.     

The Olympic Games as a career change-event: Israeli athletes' and coaches' perceptions of London 2012

ObjectivesThis study used the Scheme of Change for Sport Psychology Practice (SCSPP; Samuel & Tenenbaum, 2011a) to examine athletes' and coaches' personal characteristics, perceptions of, coping with, and perceived outcome of the London 2012 Olympic Games (OGs). We also contrasted several sub-groups (e.g., Olympic and Paralympic athletes) in certain variables, and examined the decision-making and support systems involved in the OGs change process.Design and methodsA cross-sectional and retrospective design was used. Israeli Olympic and Paralympic athletes and coaches (N = 61) completed measures of change-event experiences (Samuel & Tenenbaum, 2011b) and athletic/coaching identity (AI/CI; Brewer & Cornelius, 2001) two years after the London 2012 OGs.ResultsOlympic athletes trained more, and had higher motivation and AI than Paralympic athletes. The OGs were perceived as a significant and positive change-event in the participants' careers. AI/CI was associated with the perceived significance of the OGs. At the time of Olympic qualification, the participants tended either to ignore this change-event or cope with it independently. Most participants reported making a decision to change related to adjustment and coping. Professional support was mainly available prior to and during the OGs. During this experience the participants did not consider using sport psychology services, but retrospectively, valued the usefulness of this support. Athletes' motivation after the OGs was predicted from their satisfaction of coping, and their perceived outcome of this change-event was predicted from their satisfaction of competition results.ConclusionsPsychological support must be provided as part of the Olympic cycle, especially in promoting a decision to change. Maintaining realistic expectations may be critical for facilitating a positive perception of this change-event.     

Influence of warmth and competence on the promotion of safe in-group selection: Stereotype content model and social categorization of faces

Categorizing an individual as a friend or foe plays a pivotal role in navigating the social world. According to the stereotype content model (SCM), social perception relies on two fundamental dimensions, warmth and competence, which allow us to process the intentions of others and their ability to enact those intentions, respectively. Social cognition research indicates that, in categorization tasks, people tend to classify other individuals as more likely to belong to the out-group than the in-group (in-group overexclusion effect, IOE) when lacking diagnostic information, probably with the aim of protecting in-group integrity. Here, we explored the role of warmth and competence in group-membership decisions by testing 62 participants in a social-categorization task consisting of 150 neutral faces. We assessed whether (a) warmth and competence ratings could predict the in-group/out-group categorization, and (b) the reliance on these two dimensions differed in low-IOE versus high-IOE participants. Data showed that high ratings of warmth and competence were necessary to categorize a face as in-group. Moreover, while low-IOE participants relied on warmth, high-IOE participants relied on competence. This finding suggests that the proneness to include/exclude unknown identities in/from one's own in-group is related to individual differences in the reliance on SCM social dimensions. Furthermore, the primacy of the warmth effect seems not to represent a universal phenomenon adopted in the context of social evaluation.     

Inhibiting reactions to emotional versus non‐emotional response cues in schizophrenia: Insights from a motor‐process paradigm

Recent models of schizophrenia suggest deficient use of contextual response cues when confronted with countermanding emotional cues. It is important to clinically validate these models by testing patients diagnosed with schizophrenia on tasks with competing emotional and contextual response determinants. Control and schizophrenia groups completed a novel task that elicited motor responses consistent with, or in opposition to, pre‐potent emotional actions (i.e., approach vs. avoidance). An analogous non‐emotional task was also used to examine cue‐conflict impairment more generally. The groups demonstrated statistically equivalent performance decrements on incongruent versus congruent trials on both tasks. However, within the schizophrenia group, the incongruency effect was significantly greater in the emotional versus non‐emotional task. These data suggest that, while patients with schizophrenia were able to employ contextual response cues to override competing emotional responses, they were slower to resolve emotional versus non‐emotional response conflict. When patients were subdivided according to the presence or absence of disorganized symptoms, this effect was confined to patients with disorganized symptoms.
