Emerging selves: representational foundations of subjectivity

A hypothetical evolutionary scenario is offered meant to account for the emergence of mental selves. According to the scenario, mental selves are constructed to solve a source-attribution problem. They emerge when internally generated mental contents (e.g., thoughts and goals) are treated like messages arising from external personal sources. As a result, mental contents becomes attributed to the self as an internal personal source. According to this view, subjectivity is construed outward-in, that is, one's own mental self is derived from, and is secondary to, the mental selves perceived in others. The social construction of subjectivity and selfhood relies on, and is maintained in, various discourses on subjectivity.     

Engagement in Child and Adolescent Treatment: The Role of Parental Cognitions and Attributions

Parental engagement in the treatment process is influenced by parents' beliefs about the cause of their children's problems, perceptions about their ability to handle such problems, and expectations about the ability of therapy to help them. This paper examines the role of parental cognitions related to attributions and expectations in relation to engagement in child mental health treatment. Reviewed studies indicate that parental attributions and expectations influence three aspects of treatment: help seeking, engagement and retention, and outcome. This paper integrates findings from developmental and clinical research, highlights gaps in the literature, presents the beginnings of a model regarding the parental attributional process as it relates to engagement in treatment, recommends future research directions, and discusses clinical implications.     

Locus of the effect of specific practice in continuous visual search

Specific practice in a visual search task can result either in a selective elaboration of the feature lists of the task stimuli or in a selective emphasis of their status within the task (targets vs. nontargets). According to the first explanation, which is related to the differentiation principle of perceptual learning, specific practice enhances the operation of stimulus identification. According to the second explanation, which is related to the enrichment principle of perceptual learning, it enhances the operation of response selection. Evidence from two transfer experiments with a reversal paradigm argues in favor of the second view, at least for tasks with easily codable letter stimuli. The results are discussed in the framework of a recent model of information integration in visual search.     

Commentary: The Fast Track Project: A Seminal Intervention Efficacy Trial

The Fast Track Project is a seminal intervention efficacy trial with several hallmark features, including theoretically driven intervention components, rigorous implementation, and integrity in how results are characterized. Critical issues are discussed in relation to sustainability, a controversy over what really constitutes prevention, and replicability.     

Critical issues in the prevention of violence-related behavior in youth

Violence prevention programs with varying degrees of scientific support have proliferated in the United States and elsewhere. This paper previewed a broad range of programs involving youth, families, or systems that aimed to prevent or reduce violence-related behavior. The purpose of the review was to address critical issues concerning (1) target level of programming, (2) theory-driven versus problem-driven conceptualization, (3) cultural considerations, (4) developmental considerations, (5) intervention fidelity, and (6) outcome and impact assessment. Conclusions about these issues address tendencies and trends across programs.     

Recognition of self-generated actions from kinematic displays of drawing

Five experiments addressed the question of whether individuals can distinguish between self-generated and other-generated actions when seeing their visual effects. Each experiment consisted of a recording session in which participants drew familiar and unfamiliar characters without receiving visual feedback and a recognition session in which they provided self-or-other judgments (SOJs) to indicate whether a kinematic display reproduced the visual effects of their own actions. The main results were that self-generated and other-generated drawing can be distinguished, that the familiarity of character shapes does not influence the accuracy of SOJs, and that velocity information is crucial for the identification of self-generated drawing. The ability to determine authorship from kinematic displays of drawing provides evidence for the contribution of action-planning structures to perception.     

Two modes of sensorimotor integration in intention-based and stimulus-based actions

Human actions may be driven endogenously (to produce desired environmental effects) or exogenously (to accommodate to environmental demands). There is a large body of evidence indicating that these two kinds of action are controlled by different neural substrates. However, only little is known about what happens—in functional terms—on these different “routes to action”. Ideomotor approaches claim that actions are selected with respect to their perceptual consequences. We report experiments that support the validity of the ideomotor principle and that, at the same time, show that it is subject to a far-reaching constraint: It holds for endogenously driven actions only! Our results suggest that the activity of the two “routes to action” is based on different types of learning: The activity of the system guiding stimulus-based actions is accompanied by stimulus-response (sensorimotor) learning, whereas the activity of the system controlling intention-based actions results in action-effect (ideomotor) learning.     

Instrument specificity in experienced musicians

Previous studies have shown that experienced pianists have acquired integrated action-effect (A-E) associations. In the present study, we were interested in how specific these associations are for the own instrument by investigating pianists and guitarists. A-E associations were examined by testing whether the perception of a “potential” action-effect has an influence on actions. Participants played chords on their instrument in response to visual stimuli, while they were presented task-irrelevant auditory distractors (congruent or incongruent) in varying instrument timbre. In Experiment 1, pianists exhibited an interference effect with timbres of their own instrument category (keyboard instruments: piano and organ). In Experiment 2 guitarists showed an interference effect only with guitar timbre. Thus, integrated A-E associations primarily seem to consist of a specific component on a sensory-motor level involving the own instrument. Additionally, categorical knowledge about how an instrument is played seems to be involved.     

Activation of action rules in action observation

Visually perceiving an action may activate corresponding motor programs. This automatic motor activation can occur both for higher level (i.e., the goal of an action) and for lower level (i.e., the specific effector with which it is executed) aspects of an action. The authors used a tool-use action paradigm to experimentally dissociate priming effects for observing the target, the movement, or the target-to-movement mapping of a tool-use action. In 3 experiments, participants took turns in acting, observing the tool-use action of another person in trial n-1, and executing an action in trial n. Trial transitions from n-1 to n were manipulated in 4 conditions with (a) mapping repeated and movement and target changed, (b) target repeated and movement and mapping changed, (c) movement repeated and target and mapping changed, or (d) all components repeated. Results indicate priming effects for repeating the target-to-movement mapping (i.e., the action rule) of a tool-use action and suggest that a rather abstract action schema is activated during action observation.     

Joint response–effect compatibility

When performing jointly on a task, human agents are assumed to represent their coactor’s share of this task, and research in various joint action paradigms has focused on representing the coactor’s stimulus–response assignments. Here we show that the response–effect (R–E) contingencies exploited by a coactor also affect performance, and thus might be represented as if they were used by oneself. Participants performed an R–E compatibility task, with keypresses producing spatially compatible or incompatible action effects. We did not observe any R–E compatibility effects when the task was performed in isolation (individual go–no-go). By contrast, small but reliable R–E compatibility effects emerged when the same task was performed in a joint setting. These results indicate that the knowledge of a coactor’s R–E contingencies can influence whether self-produced action effects are used for one’s own motor control.
