工作记忆容量与内容相关性对类别学习的影响

类别学习是通过不断地分类练习,学会如何将类别刺激进行归类的过程。采用2(工作记忆容量:高、低)×4(内容相关性:方向、宽度、亮度、控制组)被试间实验设计,通过两个实验探讨工作记忆容量与内容相关性对基于规则类别学习和信息整合类别学习的影响。结果显示:(1)对基于规则类别学习来说,在高工作记忆容量条件下,当关注相关维度时,类别学习的成绩更好;(2)对基于信息整合类别学习来说,不管工作记忆容量如何,只要关注相关维度类别学习的成绩更好。     

不同感觉通道的节奏感知及其交互作用

节奏感知是人类独有的认知现象, 听觉在节奏加工中具有优势, 声音节奏可以更好地与肢体运动同步, 但视觉和触觉通道在节奏感知上也有着各自特点并存在广泛的交互作用。视觉通道的节奏感知较弱, 与听觉节奏同时呈现时会受到时间定位上的拉扯, 但通过加入运动信息和增强后天经验可以得到强化; 节奏刺激可以调节注意在时间上的分配使其同步化, 这种调节作用可以单通道或者跨通道地出现; 触动觉与听觉联系紧密, 人们可以通过听触通道的整合对节奏进行高级加工。     

判断与决策中的基线比例忽略

基线比例忽略是指在事件的判断中忽略相关事件统计学上的信息, 而只关注当前呈现的案例信息, 从而造成判断和决策偏差的一种现象。目前对这一现象的解释主要包括双加工理论和线性整合理论, 而影响基线比例忽略的因素有许多方面, 如信息特征、认知能力等等。在未来研究中, 应该深入分析双加工理论的作用机制以及依据模糊痕迹理论提出新的研究视角, 同时拓展在团体和公共领域中的应用性研究。     

EXPANDING INFANT MENTAL HEALTH TREATMENT SERVICES TO AT‐RISK PRESCHOOLERS AND THEIR FAMILIES THROUGH THE INTEGRATION OF RELATIONAL PLAY THERAPY

The expansion of infant mental health (IMH) to at‐risk preschoolers and their families has contributed to the integration of relational play therapy (RPT) into IMH treatment services for this population. Integrating RPT allows access to specialized play and expressive techniques specific to preschool and family development, which improves the clinical ability to meet the multiple and complex needs of at‐risk parent–child dyads and their families. This article will examine the RPT literature and explore the similarities and differences between IMH and RPT. In addition, two case studies will highlight a five‐phase, integrative clinical‐treatment process and provide insight into how IMH clinicians are integrating RPT models and maintaining adherence to the IMH treatment approach.     

A longitudinal investigation of older adults’ physical activity: Testing an integrated dual-process model

Objective: To assess the effects of conscious and non-conscious processes for prediction of older adults’ physical activity (PA), we tested a dual-process model that integrated motivational (behavioural intention) and volitional (action planning and coping planning) processes with non-conscious, automatic processes (habit).

Method: Participants (N = 215) comprised community-dwelling older adults (M = 73.8 years). A longitudinal design was adopted to investigate direct and indirect effects of intentions, habit strength (Time 1), and action planning and coping planning (Time 2) on PA behaviour (Time 3). Structural equation modelling was used to evaluate the model.

Results: The model provided a good fit to the data, accounting for 44% of the variance in PA behaviour at Time 3. PA was predicted by intentions, action planning, and habit strength, with action planning mediating the intention-behaviour relationship. An effect of sex was also found where males used fewer planning strategies and engaged in more PA than females.

Conclusions: By investigating an integration of conscious and non-conscious processes, this study provides a novel understanding of older adults’ PA. Interventions aiming to promote PA behaviour of older adults should target the combination of psychological processes.     

Response-mediated spatial priming despite perfectly valid target location cues and intervening response events

Attentional effects are often inferred from keypress reaction time (RT) studies when two sequentially presented stimuli, appearing at the same location, generate costs or benefits. The universality of these attentional attributions is challenged by data from perceptual discrimination tasks, which reveal that location repetition benefits and costs depend on whether a prior response repeats or switches, respectively. According to dual-stage accounts, these post-attentional effects may be abolished by making responses in between two target stimuli or by increasing target location certainty, leaving only attentional effects. Here, we test these accounts by requiring responses to stimuli in between targets and by increasing target location certainty with 100% valid location cues. Contrary to expectations, there was no discernible effect of cueing on any repetition effects, although the intervening response diminished stimulus-response repetition effects while subtly reducing location-response repetition effects. Despite this, there was little unambiguous evidence of attentional effects independent of responding. Taken together, the results further highlight the robustness of location-response repetition effects in perceptual discrimination tasks, which challenge whether there are enduring attentional effects in this paradigm.     

Rethinking the scientist-practitioner model: On the necessary complementarity of the natural and human science dimensions

Although the dominant scientist–practitioner model has considerable professional support, it remains the case that there is a fundamental mismatch between its conceptualisation of the practitioner as a laboratory scientist in a clinical setting and the actual requirements for good counselling practice. In particular, there is mismatch between the kind of knowledge generated in the laboratory setting and the epistemic requirements of the therapeutic situation; and between the (detached, impersonal) kind of decision-making engaged in by the laboratory scientist and the (interpersonal, interactive) kind engaged in by the practitioner. Moreover, being structural in character, these limitations cannot be rectified by piecemeal modifications of the standard model, such as those envisaged on the ‘local clinical scientist model’. Nor can the recent push towards ‘evidence-based practice’ suffice as a corrective because the core problem simply replicates itself on that level. Instead, since they derive from an unduly restrictive conception of what constitutes scientific inquiry, they require endorsement of the equal partnership of the human science template as a corrective. Moreover, far from compromising its scientific commitments, this actively facilitates rethinking the integration of science and practice in the service of the effective practice of care.
