“Enacted” auditory images are ambiguous; “pure” auditory images are not

Previous research indicates that visual images are inherently unambiguous. The present study extends this argument to auditory imagery. In Experiment 1, subjects were able to reinterpret an imaged ambiguous auditory figure, but covert subvocalization apparently aided this reinterpretation. When subvocalization was blocked, reinterpretations were eliminated. Experiments 2 and 3 generalize this finding to different procedures and stimuli. Experiment 4 explores further the role of subvocalization, by showing that the likelihood of reinterpreting an imaged stimulus is directly proportional to the degree of enactment allowed. We argue that subvocalization or enactment provides an internal stimulus that is subject to reinterpretation. Without enactment, the “pure” auditory image is as unambiguous as a visual image. Thus, in both visual and auditory modalities, images come into being as representations and so are inherently meaningful.     

Postdeployment Suicide Risk Increases Over a 6‐month Period: Predictors of Increased Risk among Midwestern Army National Guard Soldiers

National Guard (NG) soldiers returning from deployments in Iraq and Afghanistan were surveyed at 6 and 12 months following their return (N = 970). The overall prevalence of suicide risk at 6 and 12 months following their return was assessed, as were changes in suicide risk among soldiers initially at high or low risk. Factors associated with changes in risk were assessed. The percentage of NG soldiers with high suicide risk increased from 6.8% at 6 months to 9.2% at 12 months (odds ratio = 1.7, p = .02). In the 882 soldiers initially at low risk, 5.9% (52/882) became high risk at 12 months; in the 64 soldiers initially at high risk, 46.9% (30/64) became low risk at 12 months. Initial levels of depressive symptoms were predictive of changing to high risk; this association appeared to be partially explained by soldier reports of increased search in the meaning in life and higher levels of perceived stress. Because suicide risk increases over the first 12 months, continued risk assessments during this time period should be considered. Supporting soldiers to find meaning in their life after deployment and enhancing their capacity to cope with perceived stress may help prevent increases in suicide risk over time.     

Hume’s Ethics: Ancient or Modern?

At Treatise 581ff., Hume seems to ground moral distinctions in therational deliberations of the observer, thereby making sentiment expendable.Is Hume then an example of an early modern ethicist, for whom moral distinctions are derived from reason alone? I argue that Hume's use of strategiesfrom ancient ethics can help explain how reason remains subordinate to sentiment.For if to take up the point of view of the judicious spectator we musthave the right constellation of sentiments and passions (the right character, asthe ancients might say), then moral distinctions are only derivatively based onreason.     

Israel: What's a Radical Feminist Doing in a Place Like This?

These are Marcia Freedman's personal observations of the fate of feminism in Israel. Her observations reveal that the current emphasis on "machismo" could spell the decline of feminist gains, and she concludes by showing the country's need for a strengthened feminism and a realistic cooperation between men and women. Freedman was a member of the Knesset in Jerusalem at the time she made these observations.     

The capacity for selective concentration on color versus form of consonants

The concept of active exclusion or inhibition of some stimuli while focusing on others has been largely ignored or rejected in recent work in the field of attention. As part of an ongoing series of studies involving five posthypnotically cued levels of mental concentration, it was possible to test the capacity for active blurring of one stimulus attribute (form) while simultaneously perceiving another attribute (color) accurately. In lowered concentration conditions three highly trained hypnotic Ss were dramatically successful in blurring the form and thereby impairing identification of colored consonants flashed tachistoscopically at speeds ranging from 300 msec down to 50 msec—without any concomitant loss in accuracy of identification of the color in which the letter was printed. Among a supplemental series of control experiments, it was further demonstrated that the active inhibitory process can be reversed so as to act upon color but not form; and that the Ss were unable to duplicate these feats in the waking state without benefit of posthypnotic programming. A theoretical interpretation of the findings, in terms of a conceptual model of the mind, is offered.
