Self in the mirror

What are mirror systems good for? Several suggestions have been made in response to this question, addressing the putative functions of mirror systems in minds and brains. This paper examines possible contributions of mirror systems to the emergence of subjectivity. At the heart of the discussion is the notion of social mirroring, which has a long tradition in social philosophy and social anthropology. Taking the existence of mirror devices in minds and brains for granted, I argue that social mirroring is a prerequisite for the constitution of mental selves, and, hence, the emergence of subjectivity. However, the fact that self and subjectivity are socially created should not be taken to indicate that they are illusory. They are as real as natural facts are.     

Achieving Population-Level Change Through a System-Contextual Approach to Supporting Competent Parenting

The quality of parenting children receive affects a diverse range of child and youth outcomes. Addressing the quality of parenting on a broad scale is a critical part of producing a more nurturing society. To achieve a meaningful population-level reduction in the prevalence rates of child maltreatment and social and emotional problems that are directly or indirectly influenced by parenting practices requires the adoption of a broad ecological perspective in supporting families to raise children. We make the case for adopting a multilevel, whole of population approach to enhance competent parenting and describe the essential tasks that must be accomplished for the approach to be successful and its effects measurable. We describe how a theoretically integrated system of parenting support based on social learning and cognitive behavioral principles can be further strengthened when the broader community supports parental participation. Implications for policy and practice are discussed.     

A bad taste in the mouth: gustatory disgust influences moral judgment

Can sweet-tasting substances trigger kind, favorable judgments about other people? What about substances that are disgusting and bitter? Various studies have linked physical disgust to moral disgust, but despite the rich and sometimes striking findings these studies have yielded, no research has explored morality in conjunction with taste, which can vary greatly and may differentially affect cognition. The research reported here tested the effects of taste perception on moral judgments. After consuming a sweet beverage, a bitter beverage, or water, participants rated a variety of moral transgressions. Results showed that taste perception significantly affected moral judgments, such that physical disgust (induced via a bitter taste) elicited feelings of moral disgust. Further, this effect was more pronounced in participants with politically conservative views than in participants with politically liberal views. Taken together, these differential findings suggest that embodied gustatory experiences may affect moral processing more than previously thought.     

Happy but overconfident: positive affect leads to inaccurate metacomprehension

When learning from text, it is important that learners not only comprehend the information provided but also accurately monitor and judge their comprehension, which is known as metacomprehension accuracy. To investigate the role of a learner’s affective state for text comprehension and metacomprehension accuracy, we conducted an experiment with N?=?103 university students in whom we induced positive, negative, or neutral affect. Positive affect resulted in poorer text comprehension than neutral affect. Positive affect also led to overconfident predictions, whereas negative and neutral affect were both associated with quite accurate predictions. Independent of affect, postdictions were rather underconfident. The results suggest that positive affect bears processing disadvantages for achieving deep comprehension and adequate prediction accuracy. Given that postdictions were more accurate, practice tests might represent an effective instructional method to help learners in a positive affective state to accurately judge their text comprehension.     

Population-Wide Parenting Intervention Training: Initial Feasibility

A population-level approach to deliver parenting and family support is a necessary but neglected approach needed to reduce the high prevalence of emotional/behavioral problems in children, decrease inadequate and potentially abusive parenting practices, and to provide improved parenting support to all parents within a specified population. We examined the initial feasibility of a large-scale professional training regimen to prepare existing service providers to implement an evidence-based preventive intervention in the realm of parenting and family support. Data from the U.S. Triple P System Population Trial are used to illustrate how a parenting and family support intervention can be successfully disseminated to a large, multidisciplinary workforce. We discuss lessons learned from this dissemination effort as well as implications for population-based approaches to child and family well-being.     

Grasp cueing shows obligatory attention to action goals

To understand the grounding of cognitive mechanisms in perception and action, we used a simple detection task to determine how long it takes to predict an action goal from the perception of grasp postures and whether this prediction is under strategic control. Healthy observers detected visual probes over small or large objects after seeing either a precision grip or a power grip posture. Although the posture was uninformative it induced attention shifts to the grasp-congruent object within 350 ms. When the posture predicted target appearance over the grasp-incongruent object, observers' initial strategic allocation of attention was overruled by the congruency between grasp and object. These results might help to characterize the human mirror neuron system and reveal how joint attention tunes early perceptual processes toward action prediction.     

Busy doing nothing: Evidence for nonaction-effect binding

Research on voluntary action has focused on the question of how we represent our behavior on a motor and cognitive level. However, the question of how we represent voluntary not acting has been completely neglected. The aim of the present study was to investigate the cognitive and motor representation of intentionally not acting. By using an action-effect binding approach, we demonstrate similarities of action and nonaction. In particular, our results reveal that voluntary nonactions can be bound to an effect tone. This finding suggests that effect binding is not restricted to an association between a motor representation and a successive effect (action-effect binding) but can also occur for an intended nonaction and its effect (nonaction-effect binding). Moreover, we demonstrate that nonactions have to be initiated voluntarily in order to elicit nonaction-effect binding.     

Two components and two stages in search performance: a case study in visual search

A model of skilled performance in visual search tasks is presented. According to the model, search behavior is controlled by two memory components. Each of them plays a different role in two stages of search. The two components are the memory representations of the target category and context category, respectively. The two stages are scan and check-for-target. It is argued that the scan is dominantly context-controlled (resulting in target detection) and that the target check is target-controlled (leading to target identification). The model is tested in a transfer experiment. It is shown that the model must be revised to account for two different ways of processing, depending on properties of the stimulus lists: (i) one-stage-scan under target and context control and (ii) scan-and-check processing where checking is target-and-context controlled and scanning is not under memory control at all. Implications of these findings are discussed.     

Integration of information in visual search

Two experiments studied how information about the nontarget items in a visual search task is used for the control of the search. The first experiment used the detection of “hurdle” stimuli to demonstrate that efficient memory representations of the context items can be established within each particular trial. This finding is explained by a model for the short-term integration of context information. The second experiment which varied the complexity of the local but not the global context provided some information about the nature of the integration operations involved. In its final version the model postulates two stages of processing with independent mechanisms of integration. Spatial integration at the first stage deletes repetitions within small samples. Temporal integration at the second stage stores and primes the memory representations of the context items over larger intervals. It is assumed that transient temporal integration within trials is mediated by the same mechanism that underlies permanent temporal integration between trials.
