Two-Year-Old Children's Understanding of Visual Perception and Knowledge Formation in Others

A landmark study by O'Neill (1996 O'Neill , D. K. ( 1996 ). Two-year-old children's sensitivity to a parent's knowledge state when making requests . Child Development , 67 , 659 – 677 .[Crossref], [Web of Science ®] , [Google Scholar]), in which 2-year-old children were found to be more likely to point toward a hidden object to help an adult who was unsighted during the hiding event than to point helpfully for an adult who had been sighted, seems to undermine the conventional assumption that children this young do not understand the relationship between seeing/not seeing and knowing/not knowing. Concerns remain, however, as to whether the children's success was mentalistic or behavioral. In two experiments, 2-year-old children received first-person experience with two kinds of glasses of different colors but with apparently identical opaque lenses, one of which blocked their vision and the other of which they could see through. When the parent was wearing these glasses, the children were able to use their own first-person experience of the glasses to infer whether the adult could see or not. Despite this, they did not understand the causal relationship between visual perception and knowledge formation, as demonstrated by their indiscriminate pointing behavior in response to an ignorant or a knowledgeable parent. However, in a third experiment, we examined the relationship between experience of the adult's behavioral incompetence when wearing glasses of a certain color and the children's pointing behavior. Here they tended to point appropriately. We conclude that the phenomenon reported by O'Neill (1996 O'Neill , D. K. ( 1996 ). Two-year-old children's sensitivity to a parent's knowledge state when making requests . Child Development , 67 , 659 – 677 .[Crossref], [Web of Science ®] , [Google Scholar]) yields to an account in terms of the 2-year-olds' assumptions about behavioral competence/incompetence rather than about knowledge/ignorance.     

The volitive and the executive function of intentions

Many philosophers of action, including Bratman and Mele, conceive intentions functionally, as executive states: intentions are mental states that represent an action and tend to cause this action. In the philosophical tradition (e.g. for Aristotle, Thomas Aquinas, Leibniz, Kant) another function of intentions, which may be called “volitive”, played a much more prominent role: intentions are mental states that represent what kind of actions we want and prefer to be realised and thus, in a possibly rational way, synthesise our motivational, desiderative, and perhaps affective as well as cognitive attitudes towards this action. This paper argues that intentions must fulfil both functions and then develops a concept of ‘intention’ that integrates both functions. One reason for including the volitive function in the definition of ‘intention’ is that only via this function the value of actions as such is realised, namely to enable the person, the kernel of the self to express herself and to control the world. Various forms of dissociation of the two functions are discussed and a proposal how to deal with such cases in the definition of ‘intention’ is developed.     

Causality and the categorisation of objects and events

The “Tower of London” puzzle was adapted to tablet PCs to be used as a clinical bedside test. “Iso-problems”, a specific class of problems, require identical moves but ball colours are permuted. Thus difficulty is the same even if the appearance is different. We wanted to determine the impact of these as yet little-studied tasks and hypothesised that there may be a learning effect specific to them (the “iso-effect”). We interspersed a set of six iso-problems within one selection of 22 tasks and analysed problem solving by 81 healthy adults (mean age 41.6 years). Participants showed learning across iso-problems (less time, fewer moves, increasingly efficient solutions). This effect was distinct from general learning, as was obvious from comparison with a series of non-isomorphic tasks. However, participants seem not to be aware of solving such problems. This “iso-effect” may be related to implicit memory, a domain that so far has not been assessed using the Tower of London.     

A Practical Explication of the Knowledge Rule of Informative Speech Acts

Abstract: This paper defends the knowledge rule of informative speech acts. It is argued that Edward Craig's insightful practical explication of the concept of knowledge can be extended to motivate the knowledge rule. A number of problem cases for the knowledge rule are addressed and accommodated.     

Wiederkehrende,primäre Kopfschmerzen im Jugendalter

Background

Recurrent pain, especially primary headache, is a serious health problem in adolescents. Music therapy in the treatment of children with migraine has already been evaluated. The aim of this pilot study was to adopt this treatment manual for adolescent patients with recurrent primary headache in preparation for the main randomized controlled trial.

Patients and methods

In this pilot study two different modes of treatment (standard and compact treatment) were tested in an outpatient setting with 19 patients. Frequency and intensity of headache symptoms were evaluated using pain diaries for 8 weeks in a pre-post design.

Results

The pilot study showed good feasibility of both treatment conditions in outpatient practice. Patients reported a reduction of pain frequency and intensity in both groups. The evaluation of the clinical relevance of these effects remains the objective for the main trial.

Conclusions

The music therapeutic treatment plan for children with migraine is even feasible in the treatment of adolescents with recurrent, primary headache. Further evidence questioning the effectiveness of the treatment under controlled conditions is needed.

     

Does early-career underemployment impact future career success? A path dependency perspective

Whereas many studies have shown that underemployed people experience lower objective career success and lower subjective career success while being underemployed, little research has been done on the lasting effects of underemployment. This study addresses the role of time in career success research by examining the impact of level underemployment, content underemployment and contingent employment on subsequent objective (i.e. salary) and subjective career success (i.e. job satisfaction). Our 10-year longitudinal dataset of 335 Dutch university graduates permits us to examine the impact of preceding underemployment as well as the specific timing of the underemployment in one's career. The multilevel analysis results illustrate that level and contingent underemployment have a negative impact on future pay, whereas content underemployment negatively affects job satisfaction five years later. In addition, for level underemployment also the timing turns out to matter, suggesting that the signal that it sends to employers may differ depending on when in one's career it happened. Taken together, these findings point to the importance of using a path-dependency perspective when trying to understand people's career success.     

Integration sozialarbeiterischer Kompetenz in die psychotherapeutische Versorgung

Social and socioeconomic issues are a risk factor for the development of mental health problems and have the potential to negatively impact the psychotherapeutic treatment process. In addition, mental disorders can also result in socioeconomic stress. Neither professional training nor parameters of everyday practice of medical or psychological psychotherapists are geared towards acquiring sufficient competence to adequately handle complex social problems of highly impaired patients. Especially in times of social crises, three interrelated strategies may be helpful: to enhance psychotherapists’ sensibility and competence to recognize and deal with severe social crises, to promote cooperation with clinical social workers and to incorporate sociotherapeutic elements in the overall treatment planning. Using an approach of integrated care at a university medical department as an example, this article presents examples of how to implement these strategies into everyday therapeutic practice.
