American and Danish police “dropout” rates: Denmark's force as a case study in high job satisfaction,low stress,and low turnover

An excessive “dropout” rate among police officers—quitting prior to normal retirement—wastes resources and may result in a low level of experience. Denmark's police force appears to be a case study in low turnover and may provide valuable insights. A primarily qualitative analysis contends that factors related to Danish culture and police practices produce relatively low stress and high “need fulfillment” for Danish officers in comparison with their counterparts in typical U.S. police departments—variables previously found related to low turnover. Results of a mail questionnaire show rates of early leaving (prior to retirement) notably lower for the Danish police than for a U.S. national sample of 87 police departments in large cities, and a special subsample of 39 small-city departments in California. Qualifications and implications are discussed.     

Some aspects of language comprehension in anterior aphasia

The competency of language comprehension was evaluated in three groups: anterior aphasics, posterior aphasics, and normal control subjects. Test material was divided into two sentence groups (Fill in the Blank and True/False) emphasizing either (1) semantic, “real world,” identity words or (2) syntactic, relational words, and one paragraph interpretation task. Matching auditory and visual (written) presentations were given. The control subjects performed almost flawlessly but many errors were made by each aphasia group. Qualitative study revealed a marked difference in the comprehension problem of the two groups. The anterior aphasic group performed well on semantically weighted sentences but made errors on syntactically weighted material, regardless of mode of presentation. In contrast, the posterior aphasics made almost the same number of errors on both types of material, regardless of mode of presentation. These findings support the concept of defective language comprehension in anterior aphasia and further suggest that the defect centers on the syntactical structures which are also poorly handled in expressive output.     

Asymmetries for the categorization of kanji nouns, adjectives, and verbs presented to the left and right

Kanji is one form of written Japanese in which the symbolic/analytic characteristics of language are dissociated from systematic phonetic characteristics; as such, it makes possible a more careful test of which aspect of language is responsible for the frequently observed superior left-hemisphere performance. In this study, subjects were asked to categorize tachistoscopically presented kanji as nouns, adjectives, or verbs. The previously reported (Hatta 1977, Neuropsychologia, 15, 685–688) left-visual-field advantage for kanji was found only in the case of nouns. Adjectives and verbs were processed more rapidly and correctly in the right visual field.     

Thomas Aquinas and Antonio de Córdoba on self-defence: saving yourself as a private end

ABSTRACT

Revisionists about Aquinas’ teaching on private self-defence take the standard reading to hold that Aquinas applies a version of the Doctrine of Double Effect (DDE) according to which the intentional killing of a wrongful attacker by a private person is morally prohibited while the non-intentional but foreseeable killing of the attacker is permitted. Revisionists dispute this reading and argue that Aquinas permits the intentional killing of wrongful attackers. I argue that revisionists mischaracterize the standard reading of Aquinas. I consider one of its main proponents, Antonio de Córdoba (1485–1579). When Córdoba condemned the intentional killing of wrongful attackers by private persons, he was not applying DDE. Rather, he was arguing that when you decide to kill an attacker you treat the attacker as a resource for the private end of saving your life. Killing a member of your community is a form of irrevocable social exclusion. This decision ought to be left to the public authorities. The disagreement between the authors defending the standard view and their critics was not about DDE but rather about the moral limits that membership in a community sets on the pursuit of private ends, including the private end of staying alive.     

Do Split Brains Listen to Prozac?

Abstract. Cognitive science challenges our understandings of self and freedom. In this article, adapted from a chapter in Minding God: Theology and the Cognitive Sciences (Peterson 2003), I review some of the scientific literature with regard to issues of self and freedom. I argue that our sense of self is a construct and heavily dependent on the kind of brain that we have. Furthermore, understanding the issue of freedom requires an understanding of the findings of cognitive science. Human beings are constrained to be free; our biology in no small way determines the kinds of freedom that we are able to have.     

Agrammatism in a case-inflected language: Comprehension of agent-object relations

Yugoslav agrammatic aphasics and normal control subjects were tested for comprehension of agent-object relations in a series of simple Serbo-Croatian sentences consisting of two nouns (N) and a transitive action verb (V). The availability of nominative and accusative case inflections and a semantic contrast was systematically varied across sentences. Sentences were also varied with respect to the two sequences NVN and VNN. An analysis of subjects' agent-object assignments yielded the following results: While Broca's aphasics did show some sensitivity to case inflections, their ability to process such cues was greatly impaired relative to normal subjects, for whom morphological cues were almost completely deterministic. To a lesser degree, Broca's aphasics were impaired in their ability to employ a strategy of “choose the first noun as agent” when case inflections and semantic contrasts were not available. While Broca's aphasics showed no impairment in their ability to exploit semantic contrasts for agent-object assignment, there was no absolute compensatory increase in the degree to which they relied on semantic cues. Differences in word sequence had no effect on agent-object assignment in Broca's aphasics. Finally, Broca's aphasics frequently responded unsystematically when cues to agent-object relations occurred in isolation or in competition with one another, but when there was a convergence of cues their performance approached that of normal subjects. This result was interpreted in terms of an accessing hypothesis.     

Sex and handedness differences in EEG measures of hemispheric specialization

EEG alpha asymmetry was studied in 90 normal adults: right-handed, left-handed, and ambidextrous, male and female. Recordings were made from homologous central, parietal, and occipital leads, referenced to vertex, while subjects engaged in writing, speaking, reading, listening to speech, singing, and block design construction. These data confirm our previous findings that alpha asymmetry is task-dependent and extend them to a broader range of tasks, subjects, and leads. Among right-handers significant differences were found between the language tasks and the musical and spatial tasks: the $\text{R}\text{L}$ alpha ratio is higher in the language tasks. In addition, significant ordering of $\text{R}\text{L}$ alpha ratios was found among the language tasks themselves: WRITE å SPEAK > READ > LISTEN. No one “verbal” task can be considered representative of all language behaviors. Task differences in asymmetry were greater at the central than at the parietal leads, and no differences were found at the occiput. Differences among the handedness groups were found in $\text{R}\text{L}$ alpha ratio in specific tasks, in the relationship among tasks, and in alpha power level. Non-right-handers showed less task-dependent asymmetry. On some measures ambidexters appear to be a distinct group, not simply representing the middle range of a left-handed/right-handed continuum. Reversal of the “expected” right-handed pattern (SPEAK $\text{R}\text{L}$ ratio > BLOCKS $\text{R}\text{L}$ ratio) was seen in 10% of right-handers, and in 36% of left-handers, particularly among left-handed females (46%), suggesting a possible sex difference among non-right-handers. No sex difference was found among right-handers on any task with any measure at any lead.     

Hemispheric memory for random forms revisited

Hemispheric short-term memory was studied by projecting complex random forms that varied in their verbal association strength to the left and right hemispheres. Male and female subjects responded same or different to a centrally presented memory test stimulus which occurred 0, 5, 10, or 20 sec after the target item. Reaction time for both response judgments was significantly shorter for right-hemisphere presentations over all memory intervals. For both performance measures, response judgment interacted with the length of memory interval and the verbal association value of the stimulus items. No hemispheric differences were observed as a function of subject sex. Hemispheric memory for complex forms appears primarily dependent upon task processing demands rather than stimulus factors when response time is used to measure recognition under tightly controlled conditions.     

“Masculinity,” “femininity,” and adjustment in college men

The regression of adjustment—indexed by measures of anxiety and depression— on “masculinity” (instrumentality) and “femininity” (expressiveness)—as assessed by the BSRI, PRF ANDRO, and the Short BSRI—was studied in 122 college men. The findings revealed that: (a) anxiety and depression marked a single adjustment factor; (b) self-esteem mediated the relationships between instrumentality, expressiveness, and adjustment, such that when the variance due to it was removed, neither instrumentality nor expressiveness accounted for significant variance in Anxiety-Depression; (c) the Short BSRI index of expressiveness behaved differently from the other indices and more like that of the PAQ; (d) instrumentality and expressiveness interacted significantly, such that instrumentality was positively associated with adjustment for those with low or average expressiveness and expressiveness was positively associated with adjustment only for those with low or average instrumentality; and (e) men high in instrumentality and low in expressiveness reported slightly higher adjustment than “androgynous” men.
