Categorizing the Body

I shall attempt to do four things in this paper:

(1) sketch the influence of two models—one essentialist, the other non-essentialist—on some contemporary ways of categorizing the body;

(2) indicate certain tensions that remain because of the dominant influence of the essentialist model;

(3) discuss what to my mind is the most sustained attempt by phenomenology to come to terms with the problem of the body by concentrating on Merleau-Ponty's theory of operative intentionality;

(4) argue that intentionality and ontological analysis must always be distortive of this issue, and indicate an alternative way of approaching the matter.     

The precuneus and the insula in self-attributional processes

Attributions are constantly assigned in everyday life. A well-known phenomenon is the self-serving bias: that is, people’s tendency to attribute positive events to internal causes (themselves) and negative events to external causes (other persons/circumstances). Here, we investigated the neural correlates of the cognitive processes implicated in self-serving attributions using social situations that differed in their emotional saliences. We administered an attributional bias task during fMRI scanning in a large sample of healthy subjects (n = 71). Eighty sentences describing positive or negative social situations were presented, and subjects decided via buttonpress whether the situation had been caused by themselves or by the other person involved. Comparing positive with negative sentences revealed activations of the bilateral posterior cingulate cortex (PCC). Self-attribution correlated with activation of the posterior portion of the precuneus. However, self-attributed positive versus negative sentences showed activation of the anterior portion of the precuneus, and self-attributed negative versus positive sentences demonstrated activation of the bilateral insular cortex. All significant activations were reported with a statistical threshold of p ≤ .001, uncorrected. In addition, a comparison of our fMRI task with data from the Internal, Personal and Situational Attributions Questionnaire, Revised German Version, demonstrated convergent validity. Our findings suggest that the precuneus and the PCC are involved in the evaluation of social events with particular regional specificities: The PCC is activated during emotional evaluation, the posterior precuneus during attributional evaluation, and the anterior precuneus during self-serving processes. Furthermore, we assume that insula activation is a correlate of awareness of personal agency in negative situations.     

Attentional biases for faces and body parts

In four experiments, we examined whether faces and body parts are processed faster and engage attention more than other objects. Participants searched for a green among blue frames and were asked to make speeded categorical decisions on an object presented within the target frame (e.g., was it food?). On half of the trials a colour singleton (a red frame) was also present and reaction times to targets were measured as a function of the object category within the singleton. The results show that categorical judgements of faces (Experiments 1–3) and body parts (Experiment 4) in the target frame were significantly faster as compared to other object categories. Furthermore, the cost associated with presenting a face or body part in the singleton frame was greater than the cost when another type of object was in the singleton. These results suggest an attentional bias towards stimuli of sociobiological significance such as faces and body parts.     

Problem-solving style,achievement motivation,psychological distress and response to a simulated emergency

The relationship between problem-solving style, achievement motivation, psychological distress and effectiveness in an emergency situation was investigated in 107 volunteers in a simulated aircraft disaster. Effectiveness was measured in terms of the speed of egress averaged across four trials and the total number of bonuses earned. The best predictor of speed of egress was problem-solving confidence, while those who earned most bonuses tended to score higher on problem-solving creativity, dominance and status aspiration. The implications for the training of emergency service personnel are discussed.     

The Consequences of School Environment and Locus of Control on Adulthood Deviant Behavior

We examine the long-term effect of school environment on individual deviant behavior. Specifically, we contrast the effects of school deviance and students’ perception of school deviance on personal deviance later in life. Using longitudinal data from four waves of more than 3,100 participants in the Kaplan Longitudinal and Multigenerational Study, we are able to show that school deviance in 7th grade has only a short-term effect on individual deviance. However, when students perceive a lack of deviance in their school at 7th grade, it decreased their personal deviance in their mid-forties if they were both deviant in 7th grade and reported an external locus of control.
