Phonetic recalibration only occurs in speech mode

Upon hearing an ambiguous speech sound dubbed onto lipread speech, listeners adjust their phonetic categories in accordance with the lipread information (recalibration) that tells what the phoneme should be. Here we used sine wave speech (SWS) to show that this tuning effect occurs if the SWS sounds are perceived as speech, but not if the sounds are perceived as non-speech. In contrast, selective speech adaptation occurred irrespective of whether listeners were in speech or non-speech mode. These results provide new evidence for the distinction between a speech and non-speech processing mode, and they demonstrate that different mechanisms underlie recalibration and selective speech adaptation.

Three dimensions of coping and a look at their evolutionary origin

Serious problems persist concerning the conceptualization and measurement of the coping construct. This study examines the properties and factor structure of the COPE questionnaire, one of the most widely used instruments to measure coping, in a sample of 471 patients. A series of exploratory factor procedures are applied at the item- and scale-level, and the resulting solutions are tested both by their congruence with previously published structures and by confirmatory techniques. Our finding of three robust, generalizable, and parsimonious second-order dimensions—Engagement, Disengagement, and Help-Seeking—challenges the original structure. The results are discussed from an evolutionary perspective, on the assumption that the recognition of coping as the activation of vestigial defenses may make a substantial contribution to clarifying its functions and organization.

The Coming-Out Process and Its Adaptational and Health-Related Associations Among Gay, Lesbian, and Bisexual Youths: Stipulation and Exploration of a Model

A model is proposed and explored that links the coming-out process to the psychological functioning (i.e., self-esteem and distress) and sexual behaviors of gay, lesbian, and bisexual youths recruited from gay-focused community-based and college organizations in New York City. The coming-out process is multidimensional, consisting, as defined here, of involvement in gay/lesbian activities, attitudes toward homosexuality, comfort with homosexuality, self-disclosure of sexual identity to others, and sexual identity. The coming-out dimensions were related to self-esteem, distress, and unprotected sexual behaviors. In addition, the relations between the coming-out dimensions and unprotected sexual behaviors were explained by psychological functioning. In particular, limited involvement in gay/lesbian activities was associated with more unprotected sex. Negative attitudes toward homosexuality were related directly to more unprotected sex, and they were related indirectly to more unprotected sex by means of increasing emotional distress. These and other findings have implications for designing preventive interventions to increase the youths' psychological functioning and reduce their unprotected sexual behaviors.     

Evolution of Destructive Aggression

Aggression is defined as a mechanism of spacing by means of force or displays. It has evolved independently in different animal groups. The mechanisms underlying it are therefore not homologous throughout the animal kingdom. The phenomenon of aggression is so widespread, however, that strong selection pressures must be responsible for its development along analogous lines. Its most obvious functions are in competition for mates, natural resources, and territories, and in the preservation of group identity in many gregarious species. Aggression is often ritualized so that no damage is done to conspecifics. This ritualization may appear as modification of fighting into a tournament, or as the development of submissive postures which block further aggression in the opponent shortly after the onset of a potentially damaging fight. Animal aggression is preprogrammed by phylogenetic adaptation in well-defined ways, but can be modified by experience. The inborn programs involve motor patterns, innate releasing mechanisms, releasers, motivating mechanisms, and learning dispositions specific for the species. Aggression on this biological level can be observed in humans as intragroup aggression. Certain motor patterns and signals which lead to the release of aggression are universal. Some can even be found in deaf- and blind-born people, proving their innateness. A number of patterns of aggression in man are highly ritualized and - in a way analogous to that found in many animals - mechanisms of control have evolved inhibiting the killing of a conspecific. There are strong indications of the existence of motivating mechanisms within the brain, e.g., in the form of neuronal circuits, that show a degree of spontaneity. The type of destructive aggression which we call war, is a product of cultural evolution. War takes advantage of the given motivational structure of man, including his fear of strangers, which develops in every baby independently of experience and makes men inclined to form closed groups and causes them to be wary of or hostile to strangers. Based on these tendencies, man underwent a process of cultural subspeciation. Groups demarcated themselves from others by custom, erecting communication barriers. The development of languages demonstrates how fast and efficient this process is. Members of the same group, during this process, were defined as the “real man,” outsiders often were to be valued less -or even considered nonhuman. On the basis of this self-indoctrination, cultural codes of conduct developed, which allowed members of other groups to be killed when groups competed for resources. A cultural fiiter of norms was established which demanded killing under defined conditions, and was superimposed upon the biological filter of norms which inhibits the killing of a human being. This results in a conflict of norms, which is universally felt as guilt, since the biological filter of norms, though superimposed, is nonetheless working, particularly in the circumstance of a personal encounter. The more advanced the technique of armament, which allows fast and distant killing, the less the inhibitions are activated. Nonetheless, ritualizations occur on the cultural level. Warfare is sometimes ritualized and conventions are developed to prevent escalation into massacres, or the wholesale destruction of the subjugated enemy. To a great extent, this is certainly a result of our inborn moral code, If nothing like this were given to man our situation would be disastrous indeed. Whether cultural evolution will, in the future, be guided by moral maxims in accord with our human nature is a deeision men must make rationally. Although a ruthless ethnocentrism may bring advantage to a warring group, this may eventually prove fatal to mankind as a whole. In the escalating competition mankind runs the danger not only of exhausting its resources, but of destroying itself with its new weapons. If the outcome were not selfdestruction but domination by one group it would impoverish the diversity of human cultures, and thus seriously cut down man's spectrum of adaptability. War fulfills certain functions, similar to those found in animals. It is mainly a mechanism for preserving and extending one's territory, and a means of getting access to scarce resources. It is therefore dangerous to consider war merely as a pathological form of human behavior because this may distract our attention from the fact that, h order to overcome war, the functions of war have to be fulfilled by nonviolent means. Cultural evolution phenocopies biological evolution, due to similarities in the selection pressures shaping its course. This allows us to define the point of the evolutionary spiral we are at currently and to predict our future course.     

Mechanisms of long-term dark adaptation

It has previously been suggested that long-term dark adaptation is controlled by bleaching signals that regulate the activity of an allosteric, positively cooperative protein (Stabell et al., 1986a, b). Recent biochemical evidence strongly supports this assumption, indicating that the primary regulator of the light-sensitive channels in the plasma membrane of the outer segments of the photoreceptors is a homo-oligomeric, allosteric, positively cooperative protein. In this report, we discuss the possibility that signals from bleached photopigments may control the dark-adaptation process through the allosteric protein of the plasma membrane. It is suggested that the concentrations of the bleached photopigment and of the allosteric effector are reciprocal quantities.     

The impact of defibrillator discharges on psychological functioning of implantable cardioverter defibrillator recipients

A lag exists with respect to our understanding of the psychological demands and rehabilitation needs of individuals who have undergone implantable cardioverter defibrillator (ICD) implantation. The ICD is designed to transmit an electric shock to the heart to treat a potentially life-threatening arrhythmia. This study specifically examined the impact of defibrillator discharges on the psychological functioning of ICD recipients. A questionnaire was self-administered to 33 individuals who have been living with the ICD for at least 6 months. Results revealed that levels of anger and depression were significantly higher in those subjects who reported a lower discharge rate, while sense of well-being was significantly higher in those subjects who reported a greater discharge rate. Possible explanations for our findings were proposed as well as implications for clinical intervention were discussed.

Social support and psychosocial competence: Explaining the adaptation to college of ethnically diverse students

Examined relationships among social support, psychosocial competence, and adaptation to college in a sample of 357 African American, Asian American, Latino, and white college students. Social support and active coping were significant predictors of adaptation to college, whereas locus of control was not. However, there was an interaction between ethnicity and locus of control indicating that although internal African American, Latino, and white students had higher adaptation-to-college scores than external students, the opposite was true for Asian Americans. The relationships among social support, internality, and active coping were also explored. Satisfaction with social support and internality were positively related to active coping, but locus of control and social support were unrelated. Active coping and internality were significantly related to each other for all groups except for African Americans. Although most relationships were the same across groups, these findings call attention to the role of ethnicity as a moderator of college adjustment processes.
