Some variables affecting dentists' assessment of patients' distress

Dental students estimated the pain distress and discomfort of their patients after patients received a Class II restoration (simple filing). Dentist's estimates of patient pain accounted for 36% of the variance in patient self-report responses. Dentist accuracy was significantly lower, however, for estimates of anxiety and distress. Dentist accuracy was unaffected by patient's degree of self-monitoring. There was a tendency for female dentists to demonstrate greater accuracy than male dentists, but this effect was nonsignificant. In addition, dentists' accuracy in assessing overall patient discomfort was significantly lower in that segment of the treatment procedure that was most stressful for the dentists. This article discusses theoretical explanations for this latter effect.     

What is space? A media ecology approach

We will explore the nature of space from a media ecology/Marshall McLuhan point of view. We will examine both space and time as the origin or etymology of the term ‘space’ includes both the notion of 3-space and time. We show how various media of communication influence how we perceive space and time from the origin of language to today’s digital revolution.     

Perfectionism,discrepancies, and depression: Testing the perfectionism social disconnection model in a short-term,four-wave longitudinal study

Perfectionistic concerns (i.e., negative reactions to failures, exaggerated concerns over others’ criticism and expectations, and nagging self-doubts) are linked to social disconnection and depressive symptoms. According to the perfectionism social disconnection model, perfectionistic concerns contribute to social disconnection (i.e., feeling rejected, excluded, and unwanted by others) which, subsequently, contributes to depressive symptoms. The social world is replete with chances for interpretations. In interpreting their social worlds, people high in perfectionistic concerns tend to perceive interpersonal discrepancies, a distressing form of social disconnection that involves perceptions of others as dissatisfied with them and as disapproving of them. These interpretations are also conceptualized as having depressing consequences for people high in perfectionistic concerns. This study tested whether perceived interpersonal discrepancies mediate the relation between perfectionistic concerns and depressive symptoms; 240 participants were recruited and this mediational model was tested with a four-wave, 4-week longitudinal design. Structural equation modeling with bootstrapped tests of mediation indicated the perfectionistic concerns-depressive symptoms relationship was mediated by interpersonal discrepancies (even after controlling for perfectionistic strivings). People high in perfectionistic concerns perceive others as dissatisfied with them and as disapproving of them. Feeling rejected, excluded, and unwanted by others, people high in perfectionistic concerns are vulnerable to depression.     

Eye movements enhance memory for individuals who are strongly right-handed and harm it for individuals who are not

Subjects who make repetitive saccadic eye movements before a memory test subsequently exhibit superior retrieval in comparison with subjects who do not move their eyes. It has been proposed that eye movements enhance retrieval by increasing interaction of the left and right cerebral hemispheres. To test this, we compared the effect of eye movements on subsequent recall (Experiment 1) and recognition (Experiment 2) in two groups thought to differ in baseline degree of hemispheric interaction—individuals who are strongly right-handed (SR) and individuals who are not (nSR). For SR subjects, who naturally may experience less hemispheric interaction than nSR subjects, eye movements enhanced retrieval. In contrast, depending on the measure, eye movements were either inconsequential or even detrimental for nSR subjects. These results partially support the hemispheric interaction account, but demand an amendment to explain the harmful effects of eye movements for nSR individuals.
