Three dimensions of expertise

Psychologists and philosophers tend to treat expertise as a property of special individuals. These are individuals who have devoted much more time than the general population to the acquisition of their specific expertises. They are often said to pass through stages as they move toward becoming experts, for example, passing from an early stage, in which they follow self-conscious rules, to an expert stage in which skills are executed unconsciously. This approach is ‘one-dimensional’. Here, two extra dimensions are added. They are drawn from the programme known as Studies of Expertise and Experience (SEE) and its ‘Periodic Table of Expertises’. SEE, which is sociological, and/or Wittgensteinian, in inspiration, takes expertise to be the property of groups; there are ‘domains’ of expertise. Under SEE, level of expertise grows with embedding in the society of domain experts; the key is the transmission of domain-specific tacit knowledge. Thus, one extra dimension is degree of exposure to tacit knowledge. Under SEE, domains can be big or small so there can be ‘ubiquitous tacit knowledge’, such as natural-language-speaking or other elements of general social behaviour, which belong to every member of a society. The second extra dimension is, therefore, ‘esotericity’. The resulting three-dimensional ‘expertise-space’ can be explored in a number of ways which reveal the narrowness of the analysis and the mistakes that have been made under the one-dimensional model.     

Predictors of Differential Responding on a Sentence Completion Task in Traumatized Children

Information-processing theories posit that persons who have experienced trauma may have disturbed emotional processing and therefore exhibit an excess of negative responses to otherwise neutral cues. The role of this mechanism in traumatized children has yet to be fully investigated. This study examined the relationship of varied clinical characteristics and theoretically relevant moderating variables to increased trauma related responding on a non-idiographic sentence completion task. One hundred and eighty-nine children (ages 6–17) residing at a residential home between 1996 and 2011 who had experienced physical, emotional and/or sexual abuse were administered a sentence completion task and the Trauma Symptom Checklist for Children (TSCC) shortly after their admission. Three independent raters determined whether sentence completion responses were trauma related (TRR), non-trauma related, or ambiguous. Trauma related responses were then reviewed for either avoidant/denial style responding or loss related responding. The TSCC posttraumatic stress subscale (PTS) was the only subscale that was uniquely related to TRR. A significant interaction between abuse type and PTS was found with sexual abuse moderating the effect of PTS on TRR. Additionally, age at assessment was positively correlated with both TRR and loss related responding. Time since removal from home was negatively correlated with TRR. Gender differences were found for TRR and loss related responding. These findings highlight the empirical relevance of the sentence completion task in clinical research. Results are discussed in terms of their implications for research, assessment, and intervention.     

The Protective Functions of Social Support and Coping for Women Experiencing Intimate Partner Abuse

This study evaluated two alternate models exploring protective factors in the relationship between intimate partner abuse and health: one in which social support was proposed to mediate the violence-health relation, and a second in which coping was proposed to mediate this relation, while social support would moderate the abuse-coping relation. Women were administered questionnaires measuring coping, social support, violence, and health status. Relationship violence predicted mental health status only, although mental health did predict physical health. Coping was found to serve as a mediator between abuse and health. Implications for future research and clinical applications are discussed.     

Duties to Make Friends

Why, morally speaking, ought we do more for our family and friends than for strangers? In other words, what is the justification of special duties? According to partialists, the answer to this question cannot be reduced to impartial moral principles. According to impartialists, it can. This paper briefly argues in favour of impartialism, before drawing out an implication of the impartialist view: in addition to justifying some currently recognised special duties, impartialism also generates new special duties that are not yet widely recognised. Specifically, in certain situations, impartial principles generate duties to take actions and adopt attitudes in our personal lives that increase the chance of new or different special relationships being formed—new or different friendships, family-like relationships, relationships akin to co-nationality, and so on. In fact, even if one thinks partialism is the best justification of the duties we have once in special relationships, impartialist justifications for taking steps to form such relationships should have some sway. Moreover, a little reflection shows that these duties are not as demanding or counterintuitive as one might expect.     

Responsiveness to verbal instruction during anesthesia: a pilot report

Five patients who were undergoing surgery were instructed to tense their forehead muscles. On 11 out of 12 trials, the patient's muscle tension was greater during the suggestion period than during the nonsuggestion condition.
