Comradery,community, and care in military medical ethics

Medical ethics prohibits caregivers from discriminating and providing preferential care to their compatriots and comrades. In military medicine, particularly during war and when resources may be scarce, ethical principles may dictate priority care for compatriot soldiers. The principle of nondiscrimination is central to utilitarian and deontological theories of justice, but communitarianism and the ethics of care and friendship stipulate a different set of duties for community members, friends, and family. Similar duties exist among the small cohesive groups that typify many military units. When members of these groups require medical care, there are sometimes moral grounds to treat compatriot soldiers ahead of enemy or allied soldiers regardless of the severity of their respective wounds.     

Psychological distance and emotional experience: what you see is what you get

Recent research suggests that perceiving negative emotion-eliciting scenes approaching intensifies the associated felt emotion, while perceiving emotion-eliciting scenes receding weakens the associated felt emotion (Muhlberger, Neumann, Wieser, & Pauli, 2008). In the present studies, we sought to extend these findings by examining the effects of imagining rather than perceiving such changes to negative emotion-eliciting scenes. Across three studies, we found that negative scenes generally elicited less negative responses and lower levels of arousal when imagined moving away from participants and shrinking, and more negative responses and higher levels of arousal when imagined moving toward participants and growing, as compared to the responses elicited by negative scenes when imagined unchanged. Patterns in responses to neutral scenes undergoing the same imagined transformations were similar on ratings of emotional arousal, but differed on valence-generally eliciting greater positivity when imagined moving toward participants and growing, and less positivity when imagined moving away from participants and shrinking. Moreover, for these effects to emerge, participants reported it necessary to explicitly imagine scenes moving closer or farther. These findings have implications for emotion regulation, and suggest that imagined spatial distance plays a role in mental representations of emotionally salient events.     

The role of phonology in a letter detection task

In two experiments, we investigated whether onsets and rimes have a role in the processing of written English. In both experiments, participants detected letter targets (e.g., t) in nonwords like vult faster than in nonwords like vust. This finding is consistent with Selkirk's (1982) view that sonorants (e.g., the /l/ of vult) cohere with preceding short vowels and are part of the vowel nucleus. In contrast, the /t/ of vust is part of the syllable's coda st and so is harder to isolate. Experiment 2 demonstrated that the time required for one to detect single-member codas following vowel digraphs (e.g., the t in veet) was similar to the time to detect the same target letter following a postvocalic sonorant (e.g., the t in vult). No evidence was found for onsets. The results provide support for a phonological organization among letters of printed rimes.     

Age-related changes in deferred imitation between 6 and 9 months of age

Six- and 9-month-old human infants were tested in a deferred imitation paradigm in which an experimenter performed a single action with a novel object. Although infants of both ages imitated the action when tested immediately, only the 9-month-olds exhibited imitation after a 24-h delay.     

Children's perceptions of and beliefs about facial maturity

The author studied children's and young adult's perceptions of facial age and beliefs about the sociability, cognitive ability, and physical fitness of adult faces. From pairs of photographs of adult faces, participants (4-6 years old, 8-10 years old, 13-16 years old, and 19-23 years old) selected the one face that appeared younger, older, better at remembering, smarter, more caring, friendlier, healthier, or stronger. Pairings consisted of faces at different adult age levels (young adults, middle-age adults, older adults, and very old adults.) Older participants were more sensitive to age differences in older faces and to faces more proximal in age. Children and adolescents believed that very old adult faces appeared to be less cognitively able than middle-aged faces (for children) and young adult faces (for adolescents). Very old male faces were judged to be less sociable. Old and very old faces were judged to be less physically fit than young and middle-aged faces. Significant positive correlation coefficients were found between the youngest children's abilities to discriminate between the adult faces of proximal age and youthful biases when selecting faces appearing to be more sociable and cognitively able. The results are discussed with respect to the development of facial information-processing skills and how those skills may be associated with the development of and changes in beliefs about older adults.     

Emotion context insensitivity in major depressive disorder

The present study tested 3 competing views of how depression alters emotional reactivity: positive attenuation (reduced positive), negative potentiation (increased negative), and emotion context insensitivity (ECI; reduced positive and negative). Normative and idiographic stimuli that elicited happy, sad, and neutral states were presented to currently depressed, formerly depressed, and healthy control individuals while experiential, behavioral, and autonomic responses were measured. Currently depressed individuals reported less sadness reactivity and less happiness experience across all conditions than did the other participants, and they exhibited a more dysphoric response to idiographic than to normative stimuli. Overall, data provide partial support for the positive attenuation and ECI views. Depression may produce mood-state-dependent changes in emotional reactivity that are most pronounced in emotion experience reports.     

Police-Public Interactions: The Impact of Conflict Resolution Tactics1

Following Hammock and Richardson (1992), it was hypothesized that a preference among some police officers for confrontational rather than conciliatory tactics when dealing with the public may serve to escalate a conflict and thereby explain the documented individual differences in reports of officer assaults. In order to test this possibility, preferred conflict tactics and officers' recent experiences of citizen compliance (and non-compliance) were measured for a sample of 115 English police and 48 Australian police. The results supported the hypothesized relationship by indicating a significant correlation between preferences for specific confrontational and coercive tactics and experiences of noncompliance from the public.     

A comparison of twins for degree of closeness and field dependency

An examination of Witkin's construct of field dependency was undertaken with a sample of adolescent twin pairs to determine if the degree of closeness in twin relationships would be reflected in the twins' degree of field dependency. Sixteen pairs of monozygotic (MZ) adolescent male twins and the same number of dizygotic (DZ) same-sexed male twins were administered three measures: Nichols and Bilbro's (1966) zygosity questionnaire, Paluszny and Beit Hallahmi's (1974) semantic differential measure of closeness, and Jackson's (1956) short form of the Embedded Figures Test. No significant differences were found between the MZ and DZ twin groups with regard to their expressed closeness to one another, as measured with Paluszny and Beit-Hallahmi's index of closeness; in addition, there were no significant differences between the two twin groups on the measure of field dependency. However, significant relationships of these two variables with intelligence were found and possible reasons for such an occurrence were offered.     

Color categories in macaques.

This experiment investigated whether macaque monkeys partition the photic spectrum into the same four basic hue categories that humans do, i.e., blue, green, yellow, and red. Monkeys were trained to respond in the presence of one chromatic stimulus and were tested, in extinction, for generalization to others. In extinction, the monkeys responded at similar and high levels to stimuli that fell in the same basic human hue category as the training stimulus and at similar and much lower levels to stimuli that fell in a different human hue category from the training stimulus. It was concluded that macaques and humans categorize the spectrum in a similar fashion.     

Social support networks among families of children with craniofacial anomalies

Investigated the social support available to families of children born with craniofacial anomalies and the perceived degree of satisfaction derived from these relationships. Thirty-six children (1 month to 5 years old) born with craniofacial deformities (FD) were matched by age and sex to 36 children with no significant physical or behavioral problems. The Social Support Questionnaire-Revised, the Revised Denver Developmental Screening Test, and a semistructured interview were administered. Results indicated that parents of FD children reported less available social support and were significantly less satisfied with their support. Parents of children who had more severe physical impairments and were rated as less attractive reported having less available and less satisfying social support. In particular, the social competence of the child was the most important predictor of parental social support. This result is interesting as the parents of FD children appeared to underreport the presence of behavioral-psychological problems in their children.
