在内隐学习的研究中,尽管目前已经默认了内隐学习的存在,但是,内隐学习与意识的关系,一直有着不断的争论.文章从内隐学习足否是无意识的、次级任务对内隐学习的影响和内隐学习的关系等三个方面对内隐学习的意识性研究主要的矛盾焦点进行了述评.     

The dynamics of the stream of behavior

Motivational psychology and ethology conceive of behavior as a continuous stream of activities, a conceptualization that is taken up formally in the present paper. Modeling the stream of behavior, unlike modeling an individual activity selected out of the stream, requires processes of data generation that govern the repeated overt appearances of activities through time. To this end the motivation theory of the dynamics of action, with its self-contained data generating process, is employed as a mathematical framework. The resulting theory, modeled as a continuous succession of mutually exclusive and exhaustive activities driven by the countdown of activation times, yields expectations for the relative frequencies of transitions and the distributions of transition times in a stream segment. Results supporting the theory were obtained in a series of critical tests using a unique data set provided by the artist Morgan O’Hara who has made extensive recordings of her stream of behavior.     

Looking before you leap: A theory of motivated control of action

The acquisition of volitional control depends, in part, on developing the ability to countermand a planned action. Many tasks have been used to tap the efficiency of this process, but few studies have investigated how it may be modulated by participants’ motivation. Multiple mechanisms may be involved in the deliberate exercise of caution when incentives are provided. For example, control may involve modulation of the efficiency of the countermanding process, and/or inhibitory modulation of the impulse to go. One of the most commonly used paradigms to assess control of action is the Stop Signal Task, in which a primary Go stimulus is occasionally followed by a countermanding Stop signal, allowing a Stop Signal Reaction Time (SSRT) to be inferred as the outcome of a “horse race” between the go and countermanding processes. Here, we present a computational model in which high task motivation modulates proactive pre-stimulus inhibition of the go response. This allows responses to be calibrated so as to fall within a time-window that maximizes the probability of success, regardless of trial type, but does not decrease the observed SSRT. We report empirical support for the model from a sample of typically developing children, and discuss the broader implications for operationalizing measures of volitional control.     

Mutual influence of implicit and explicit attitudes

Research and theory distinguish two types of attitude: automatic evaluative reactions and deliberate evaluative judgments, referred to as implicit and explicit attitudes, respectively. Although these attitudes are distinct, they may influence each other. Four studies tested whether implicit and explicit attitudes are both influenced by propositional and associative learning. We also tested whether changes in one kind of attitude mediate changes in the other. Study 1 found that propositional learning about novel individuals directly influenced explicit attitudes and indirectly influenced implicit attitudes through changes in explicit attitudes. Studies 2 and 3 replicated this finding and extended it by simultaneously demonstrating that associative learning through Evaluative Conditioning directly influences implicit attitudes and indirectly influences explicit attitudes through changes in implicit attitudes. Study 4 replicated these effects for attitudes toward familiar, rather than novel, targets. These results suggest that implicit and explicit attitudes can share common antecedents and influence each other.     

Good vibrations: Analytic process as coupled oscillations

This paper develops a new model for the action of psychoanalysis based on concepts from non-linear dynamics (chaos theory and complexity theory). It shows that the analyst–analysand couple may be conceptualized as a new configuration with its own properties that promote complex development in both members of the couple. These developments are an emergent result of the formation of the analyst–analysand couple and are significantly independent of the particular content of the manifest interaction of the couple. The well-studied phenomena of coupled oscillators suggest the specific features of the analysand–analyst interaction that are likely to be most important in conceptualizing analytic change. The model has substantial clinical applications since efforts to arrange for a coupled oscillator system that is central to it are distinct from many of the traditional considerations associated with creating an analytic situation.     

Changing explicit and implicit attitudes: The case of self-esteem

Three experiments investigated predictions concerning asymmetrical patterns of implicit and explicit self-esteem change. Specifically, we investigated the influence of knowledge about the own self that is momentarily salient as well as the influence of affective valence associated with the self in memory on implicit and explicit self-esteem. The latter was induced by evaluative conditioning, the former by directed thinking about oneself. We found that while evaluative conditioning changed implicit but not explicit self-esteem (Experiment 1), thinking about the own self altered explicit but not implicit self-esteem (Experiment 2). Moreover, in a third experiment, it could be shown that the effect of evaluative conditioning can spill over to the explicit level when participants are asked to focus on their feelings prior to making their self-report judgements (Experiment 3). Implications of our results are discussed in terms of recent controversies regarding dual-process models of attitudes and associative versus propositional modes of information processing.     

An evaluation of counselling and rehabilitation courses for Chronic Fatigue Syndrome

The aim of the current study was to evaluate the services offered by Action for ME to sufferers of Chronic Fatigue Syndrome using measures developed and validated in previous research. Preliminary studies had suggested that clients attending rehabilitation residential courses were benefiting from the service. A further, more in‐depth evaluation process with a greater number of health‐related outcome measures was warranted. In addition, assessment was widened to include other services offered to sufferers of the illness. Data relating to the usefulness and success of the services (rated by the clients) were also collected. Data from client volunteers were collected at baseline (that is, before intervention) and approximately six months later. Quantitative comparative analyses were conducted using within‐group comparisons to assess any improvements in scores at six‐month follow‐up from baseline. Fifty‐six participants completed wide‐ranging questionnaires assessing illness history, psychopathology, psychosocial factors and health and well‐being. Data relating to improvements in illness status and acceptability of treatment were also collected by means of global outcome measures. Both the counselling and residential groups showed improvements in many areas assessed at follow‐up. Most importantly, improvements were indicated in areas such as fatigue and the levels of disability suffered by patients. In addition, there were significant improvements in ratings of mood, anxiety, depression and physical symptoms. Overall, clients reported satisfaction with the care received and most found the services useful. All of the participants who completed the evaluation stated that they would recommend Action for ME services to fellow sufferers. The outcome of the current study is encouraging. The data presented provides evidence of the high level of support and advice Action for ME offers to sufferers of this illness. Furthermore, measurable improvements in scores relating to illness status were accompanied by improvements in mental health and psychosocial variables in the patient group.     

Capturing system level activities and impacts of mental health consumer-run organizations

Since the 1970s mental health consumer-run organizations have come to offer not only mutual support, but they have also adopted agendas for broader social change. Despite an awareness of the need for system level efforts that create supportive environments for their members, there has been limited research demonstrating how their system level activities can be documented or their impacts evaluated. The purpose of this paper is to feature a method of evaluating systems change activities and impacts. The paper is based on a longitudinal study evaluating four mental health consumer-run organizations in Ontario, Canada. The study tracked system level activities and impacts using both qualitative and quantitative methodologies. The article begins by describing the development and implementation of these methods. Next it offers a critical analysis of the methods used. It concludes by reflecting on three lessons learned about capturing system level activities and impacts of mental health consumer-run organizations.     

Genetic and environmental influences on the positive traits of the values in action classification,and biometric covariance with normal personality

Virtually all human individual differences have been shown to be moderately heritable. Much of this research, however, focuses on measures of dysfunctional behavior and relatively fewer studies have focused on positive traits. The values in action (VIA) project is a comprehensive and ambitious classification of 24 positive traits, also known as character strengths (Peterson, C., & Seligman, M. E. P. (2004). Character strengths and virtues: A handbook and classification. Washington, DC: American Psychological Association), the majority of which have received no behavior genetic attention. Using a sample of 336 middle-aged twins drawn from the Minnesota Twin Registry who completed the VIA inventory of strengths, we detected significant genetic and non-shared environmental effects for 21 of 24 character strengths with little evidence of shared environmental contributions. Associations with a previously administered measure of normal personality found moderate phenotypic overlap and that genetic influences on personality traits could account for most, but not all, of the heritable variance in character strengths.     

从视觉知觉与行为的分离看行为的计划-控制模型

知觉与行为的分离现象最早是从临床病例中发现的,以后研究者在正常人身上利用错觉实验范式继续探索该现象,并由此发展了4个模型进行解释。其中,计划-控制模型得到了众多实验事实的支持。该模型认为：行为分为计划和控制两个阶段,每个阶段都有独立的加工模块,每个模块使用不同的视觉表征;错觉影响计划阶段,但是不影响在线控制阶段。本文重点回顾了动态错觉效应对计划-控制模型的实验验证,并进行了评价和展望
