Migration and psychological status of adolescents in Turkey

The aim of this study was to investigate the influence of involuntary migration on an adolescent population that had moved with their families to either one of two culturally different locations in Turkey. One of these groups had moved from a village in Eastern Turkey to a nearby town, while the other had moved a considerable distance to a large city in Western Turkey. Comparison groups included adolescents from both regions who had never migrated. Measures of self-esteem, satisfaction with life, and social support networks were used with 305 adolescents who were between the ages of 12 and 15. Adolescents who had migrated scored lower on self-esteem and life satisfaction, and had fewer people in their social support networks than those who had not. It was also found that those who had migrated tended to be more dependent on peers than family for social support. This was probably the case because school attendance was lower for migrants, particularly for males, and the probability of full time work on the street away from their families was considerably higher.     

Family of Origin Violence and Courtship Abuse

Research has shown that family of origin violence is related to later courtship and marital abuse. Few researchers, however, have distinguished between observed and received violence as a child and expressed and received abuse in adult relationships. Questionnaires addressing these issues were completed by 336 undergraduates. Results indicated that 75% of the sample had expressed threats or actual violence and 64% had received such abuse in an intimate relationship. Only 25% had been publicly identified as a result of the violence. In this sample, 30% had parents who abused each other. Less often, the mother (9.1%) or father (8.5%) had been the sole abuser. Most (76.4%) had been abused as children. Multiple regression indicated that being abused as a child predicted receiving and expressing violence as an adult.     

Descriptive profile of sex and psychiatric diagnosis among rural and peri-urban clinic attenders in South Africa

Of 1,232 patients receiving psychiatric medication in outlying areas of South Africa more than half had diagnoses of schizophrenia. Significantly more men than women had substance-induced psychosis, while significantly more women had depressive and anxiety disorders.     

Attribution of control and teenage pregnancy

In rural Appalachia in Tennessee, data on 13 female adolescents who had experienced a pregnancy (mean age=16 years, 7 months) were compared with those on 38 female adolescents who had not experienced a pregnancy (mean age-16 years, 4 months) to test the hypothesis that teenagers who experience a pregnancy have external attributions of control over their life events. The Nowicki-Strickland Locus of Control Scale for Children was administered to determine their beliefs about causes of events in their lives. All the girls were white and matched for socioeconomic status, housing, and cultural background. The mean attribution of control to external agents score stood at 14.5 for girls who had experienced a pregnancy compared with 12.7 for those who had not experienced a pregnancy, but the difference was not significant (p=.08).54% of the cases exhibited external attributional orientation compared with 16% of the controls (p.02). This finding concurred with that of earlier studies. The fact that not all the girls who had experienced a pregnancy had external attributional orientation suggested that it is not the only factor linked to adolescent pregnancy. Studies have not identified whether external attributional orientation is a causal factor or consequence of adolescent pregnancy. A 1980 study found that women who had shown more external locus of control scores during pregnancy and tended to castigate themselves had a high probability of postpartum depression. Another study indicated that rises in depression among adolescents were linked to prechange orientations toward external attributions of control. Practitioners should selectively pay attention to teenagers who have extreme attributional orientations since many teenagers carry their pregnancies to term and choose to rear their infants. These orientations appear to pose risks for the adolescent mother and her children.     

The effects on arousal of frustration and aggressive films

In two two-by-two factorial experiments, subjects were either frustrated or not, and then were shown either a film depicting aggression or a neutral film. In the first experiment, performance on a digit-symbol test was measured before and immediately after the manipulations. Subjects who had either been frustrated or who had watched the aggressive movie performed better on the second digit-symbol test than did subjects who had experienced neither or both of these manipulations. In the second experiment, blood pressure was measured before and immediately after the manipulations. On various indices of arousal, the most arousal was shown for subjects who had been frustrated and who had watched the aggressive film. Subjects who had not been frustrated and who had not watched the aggressive film showed the least arousal, and subjects who had experienced one or the other of these manipulations were in between. Given that performance on the digit-symbol test has been shown to be an inverted U function of arousal, both of these experiments support the notion that the effects on arousal of frustration and aggressive movies are additive. This is directly counter to the idea that movies involving aggression are tension reducing for either frustrated or nonfrustrated subjects.     

The influence of individual and family characteristics upon career aspirations of girls during childhood and adolescence

The term pioneer is used for girls aspiring to male-dominated careers. This longitudinal study assesses the career choices of 68 middle-class girls during childhood (8–13 years, Phase I) and again during adolescence (13–18 years, Phase II), and investigates the relation between pioneering career choice and personal and family characteristics. Subjects were originally selected for exposure vs nonexposure to exogenous hormones during pregnancy. In childhood, pioneers were somewhat older, were more often persistent tomboys, had higher IQs, and had parents with higher educational attainment. In adolescence, paternal education was the only variable that showed the same relation to career choice. Adolescent girls who had wanted to get married at the time of the childhood assessment were now less likely to choose pioneering careers. Adolescent pioneers also had higher educational aspirations than nonpioneers and less likely anticipated being married within ten years than nonpioneers. A number of statistically borderline relationships were also observed: pioneers had somewhat fewer older brothers than nonpioneers, less often came from homes in which traditional femininity was stressed, and more frequently had mothers who had worked outside the home throughout their daughters' school years than mothers of nonpioneers. Prenatal exposure to exogenous sex hormones was not related to career choice during either childhood or adolescence.     

Masculinity, femininity, and musical composition psychological and psychoendocrinological aspects of musical and spatial faculties

Physiological and psychological masculinity and femininity were assessed in relation to musical capacities and spatial ability. Male composers had lower mean testosterone levels than male instrumentalists and male non-musicians; female composers had higher testosterone levels than female instrumentalists and female non-musicians. Testosterone in saliva was the physiological marker for androgyny. All of the groups were found to be psychologically androgynous on Bem's Sex-Role Inventory and all groups had above average spatial ability. Musicians, however, surpassed non-musicians on spatial visualization and on Witelson's Dichaptic Stimulation Test.     

Knowledge and Attitudes of Hospital Nurses in Italy Related to Near-Death Experiences

I distributed Nina Thornburg's Near-Death Phenomena Knowledge and Attitudes Questionnaire to 750 nurses in three Verona hospitals, and received 476 completed questionnaires. Questionnaire respondents had a modest knowledge of near-death experiences (NDEs). Nevertheless, respondents expressed a positive attitude towards NDEs in general, and towards patients who had had NDEs. Thirty-four percent of the nurses had personally encountered NDErs, and those nurses reported a higher level of knowledge than their colleagues who had not had that opportunity. Furthermore, in relation to the global sample, nurses who had encountered an NDEr showed attitudes that were more positive regarding both the NDE itself and the type of assistance they offered NDErs.     

Effects of noise and attack on aggression and physiological arousal

Sixty male subjects were first given either 10 shocks or 2 shocks by an experimental confederate. Two-thirds were then stimulated with loud and aversive noise while the other one-third were not so stimulated. In one of the noise-stimulated conditions, the subject was free to terminate the noise. In the other condition, the subject had no control over the noise. Subjects in all conditions were then given an opportunity to aggress against the confederate. Measures of skin conductance, pulse rate, and blood pressure were made after the subject had been shocked and again after the noise had been given. Subjects who had been given 10 shocks followed by uncontrollable noise gave shocks of longer duration than subjects in any other condition. Subjects given uncontrollable noise also showed evidence of being more physiologically aroused than those given controllable noise or no noise.This research was supported by Grant GS 40171 from the National Science Foundation to the first author.     

越老越风险规避吗？——年龄对冲动性预测决策行为的调节效应

年老化伴随着风险承担倾向的改变,而决策行为受冲动性的影响是否受到年龄的调节尚不清楚。研究采用两种不同类型的决策任务以及Barratt冲动性量表,考察老年人风险承担在自我报告和决策行为上的改变。结果显示老年人在剑桥博弈任务中更加风险寻求而在模拟充气球任务中更加风险规避。同时冲动性可以显著预测模拟充气球的行为,且该预测受到年龄的调节。研究结果提示,老年人并不是单一的更加风险规避或者风险寻求,而是与任务特异性相关。同时,冲动性可以较好的预测年轻人的决策行为,而对老年人的决策行为没有预测作用。     

Assessment of personality and demographic aspects of cohabitation and marital success

The outcomes of 68 marriages of four-year duration were compared on the basis of whether the partners had or had not cohabited premaritally. Background characteristics and personality data were assessed on those couples when there were newly married, and they were followed-up four years later to determine their current marital status, level of satisfaction, difficulty with various problem areas and the number of children born to them. No reliable differences on marital satisfaction or divorce rates between premarital cohabitors and noncohabitors were found. Cohabitors who divorced did so while reporting less marital distress than noncohabitors who divorced. Premarital cohabitors had significantly fewer children than noncohabitors. Degree of difficulty experienced on various problem areas differed between the groups. Certain personality and background variables predicted marital success differently for the two groups. Using the same selected set of six predictor variables, multiple regression equations were generated for cohabitors and noncohabitors. The cohabitors equation (R2 = .56) predicted marital success significantly more effectively than the noncohabitors equation (R2 = .28), When comparing the tri-weight vectors for these two equations, none of the predictor variables had the same influence in both groups. Theoretical implications of the findings were discussed.     

Automatic and voluntary control of attention in young and older adults

Young and older adults searched for a target character in a 3-item display. On each trial, both a symbolic cue (arrow at fixation) and a spatial cue (abrupt onset of one item) could indicate the target's position. Participants were told to use the central arrow cue on all trials because it had 75% validity. The onset cue also had 75% validity for half the participants and 25% validity for the other half. Both age groups showed about the same cost and benefit effects for the central arrow cues, but the abrupt onsets had much larger cuing effects for older adults. Young adults were able to suppress at least partially an automatic attentional response to an abrupt onset item when the arrow cue preceded the onset and had a higher validity than the onset cue. Older adults appeared to be less able to inhibit their responses to abrupt onsets and to disengage their attention from invalid onset cues than were the young adults.     

Ego-Identity Achievement and Perception of Risk in Intimacy in Survivors of Stranger and Acquaintance Rape

One hundred twenty-two women participated in a study of the relationship between acquaintance/stranger rape and the respective variables of ego-identity achievement (attainment of self-image during adolescence that integrates one's ideas of what one is and what one wants to be) and perception of risk in intimacy (perception of close interpersonal relationships as a risky proposition). Results showed that compared to women who had not been sexually assaulted, survivors of rape in general reported lower ego-identity achievement and greater perception of risk in intimacy. Focusing on acquaintance rape and stranger rape with age at the time of assault as possible moderator, it was found that lower ego-identity achievement was systematically related to acquaintance rape in women who had been raped during their adolescent years, but not in survivors of rape during adulthood. Perception of risk in intimacy was significantly higher among women who had been raped when adolescents compared to those who had been raped during adulthood, but only in relation to acquaintance rape.     

Threats and promises: Reputational consequences and transfer of credibility

This study was designed to investigate the reputational consequences of making threats and promises and how they affect subsequent credibility. Eighty-eight high school girls were given predetermined information about the past behavior of their pairmates prior to receiving influence attempts from them. Each first learned that her pairmate had (1) threatened or promised in the past and then learned whether she had (2) fulfilled or failed to fulfill her threat or promise. The subject herself then received a threat or promise from her pairmate. As anticipated, threateners were viewed less favorably than promisers. These impressions were maintained when it was learned that commitments had been fulfilled, but altered decidedly when it was learned that they had not. Credibility or lack of it was found to generalize from threats to promises and from promises to threats only under some conditions. It was concluded that the fit between existing impressions and proclaimed future activity, not a person's record for past reliability, is often the critical determinant of whether or not she is judged to be credible.

Design and implementation of a program for AIDS prevention in female prostitutes

The Companeros model of HIV infection prevention in Ciudad Juarez, Mexico, is presented as conceived by the National Institute of Drug Abuse (NIDA). 518 women who were IV drug users, sexual partners of drug addicts, or prostitutes were requested to participate, and 232 consented. Initial and follow-up AIDS assessments were utilized along with an assessment of sociodemographic variables, including knowledge, sexual behavior, use and abuse of drugs, and previous health history. Educative sessions about AIDs and sexually transmitted diseases (STDs) included group discussions and interaction, video watching, personal experiences, and sociodramas. 61% of prostitutes were 29, 12.6% were 13-19 years old, 31.1% were aged 30-39, and 8.9% were 40. 11% had no formal education, 58% had 6 years of primary and part of 3 years of secondary education, only 18.6% completed secondary education; and 13% had higher education. 19% lived in a hotel or shelter. Family disintegration reached 44%; these women did not live with their children. Only 5.2% thought they had excellent health, 51% said they had good health, 31% stated they had average health, and 12% admitted having had health problems. 14.6% had genital ulcers, 1.3% had herpes, 15% had gonorrhea, and 10% had syphilis. Since IV drug use among these women was almost nonexistent sexual relations constituted the principal risk factor. Responses to a questionnaire showed that the most frequent sexual behavior was vaginal penetration followed by fellatio; anal penetration was less common. 34.9% of the women practiced fellatio without protection, 16.3% had anal intercourse without protection. The proportion of AIDS cases in Mexico in women of reproductive age was growing at an exponential rate, possible because of misinformation about AIDS, a history of STDs, and a low rate of condom use.     

The Association of Religiosity,Sexual Education,and Parental Factors with Risky Sexual Behaviors Among Adolescents and Young Adults

This study examined the association of religiosity, sexual education and family structure with risky sexual behaviors among adolescents and young adults. The nationally representative sample, from the 2002 National Survey of Family Growth, included 3,168 women and men ages 15–21 years. Those who viewed religion as very important, had frequent church attendance, and held religious sexual attitudes were 27–54% less likely to have had sex and had significantly fewer sex partners than peers. Participants whose formal and parental sexual education included abstinence and those from two-parent families were 15% less likely to have had sex and had fewer partners.     

Personal and Organizational Characteristics of Employment Counselors

Eleven personal and organizational variables were measured in a large national sample of employment counselors. Data indicate that female counselors were younger than males, older counselors had higher educational levels than younger ones, and as the level of education increased, so did the number of professional association memberships and time spent in counseling activities. Employment counselors with first-line supervisors who had counseling experience tended to be older, spent more time in counseling activities, had higher education levels, and belonged to more professional associations than did counselors whose supervisors did not have counseling experience.
