Associations between volume of alcohol consumption and social status, intelligence, and personality in a sample of young adult Danes

Relatively few studies have investigated associations between volume of alcohol consumption and psychological characteristics in normal samples. A sub-sample, comprising 363 men and 331 women between 29 and 34 years of age, was selected from the Copenhagen Perinatal Cohort on the basis of perinatal records. The sample was divided into four consumption categories: abstainers (including occasional drinkers), light, moderate, and risk drinkers. ANOVA and relevant contrasts were used to test the significance of differences among consumption categories. Both abstaining and risk drinking were associated with low social status family background, low education and intelligence. Abstaining was associated with low disinhibition and social recognition scores, while risk drinking was associated with high neuroticism and, in males, high disinhibition, low social recognition, and low achievement scores. Compared with light drinkers, a more "carefree" life orientation characterized male moderate drinkers, while relatively high scores on anxiety, dysthymia, and somatoform symptom scales characterized female moderate drinkers.     

A genetic factor explains most of the variation in the psychopathic personality

The psychopathic personality can be conceptualized as three interrelated dimensions, (a) an interpersonal style of glibness, grandiosity, and manipulation; (b) an affective disposition of callousness, lack of empathy, and unemotionality; and (c) a behavioral/lifestyle dimension of impulsivity, need for stimulation, and irresponsibility, underpinning a higher order construct, psychopathic personality. The authors used a self-report questionnaire (The Youth Psychopathic Traits Inventory) to study the importance of genetic and environmental influences on psychopathic personality traits in a sample of 1,090 monozygotic and dizygotic twin pairs, aged 16-17 years. Results showed a strong genetic influence behind the higher order "psychopathic personality" factor, underpinned by the three psychopathic personality dimensions. Over and above the effects to the higher order factor, significant unique genetic influences were also found in the callous/unemotional and in the impulsive/irresponsible dimension, but not in the grandiose/manipulative dimension. The authors propose that this latent psychopathic personality factor is a meaningful target for future etiological research.     

Psychophysiological assessment during exposure in driving phobic patients

A comprehensive assessment of fear or anxiety requires measurement of both self-report and physiological responses. Respiratory abnormalities have been rarely examined during real-life exposure, although they are an integral part of fear. Twenty-one women with a specific driving phobia and 17 nonphobic women were psychophysiologically monitored during 2 highway-driving sessions; phobic women completed an additional session. Respiratory movements, end-tidal partial pressure of carbon dioxide, an electrocardiogram, skin conductance, and skin temperature were recorded. Phobic patients differed from control participants both physiologically and experientially before, during, and after exposure. Effect size during exposure was large for the authors' measure of hyperventilation. Discriminant analysis indicated that multiple physiological measures contributed nonredundant information and correctly classified 95% of phobic and control participants. Thus, selected respiratory and autonomic measures are valid diagnostic and therapeutic outcome criteria for this situational phobia.     

Assessing personality with a structured employment interview: construct-related validity and susceptibility to response inflation

The authors evaluated the extent to which a personality-based structured interview was susceptible to response inflation. Interview questions were developed to measure facets of agreeableness, conscientiousness, and emotional stability. Interviewers administered mock interviews to participants instructed to respond honestly or like a job applicant. Interviewees completed scales of the same 3 facets from the NEO Personality Inventory, under the same honest and applicant-like instructions. Interviewers also evaluated interviewee personality with the NEO. Multitrait-multimethod analysis and confirmatory factor analysis provided some evidence for the construct-related validity of the personality interviews. As for response inflation, analyses revealed that the scores from the applicant-like condition were significantly more elevated (relative to honest condition scores) for self-report personality ratings than for interviewer personality ratings. In addition, instructions to respond like an applicant appeared to have a detrimental effect on the structure of the self-report and interview ratings, but not interviewer NEO ratings.     

Changes in social support as mediators of the impact of a psychosocial intervention for spouse caregivers of persons with Alzheimer's disease

The spouse caregivers of 406 patients with Alzheimer's disease were randomly assigned to an enhanced counseling and support intervention or to a usual care control condition. Structured interviews were conducted to assess changes in social support and psychosocial outcomes for the 312 caregivers who provided care in the home for at least 1 year. The number of support persons, satisfaction with the support network, and support persons' assistance with caregiving all increased significantly as a function of the intervention. Structural equation models indicated increased satisfaction with the social support network mediated a significant proportion of the intervention's impact on caregiver depression. A portion of this mediated effect was further mediated by changes in caregiver stress appraisals. Implications for strengthening intervention programs for spouse caregivers of individuals with Alzheimer's disease are discussed.     

Linking adult psychopathy with childhood hyperactivity-impulsivity-attention problems and conduct problems through retrospective self-reports

The purpose of the present study was to test whether adult criminals with psychopathy diagnoses, more than those without, have histories of hyperactivity-impulsivity-attention problems (HIA) and conduct problems (CP). We compared psychopathic and nonpsychopathic violent criminal offenders on retrospective reports of conduct problems before the age of 15 and hyperactivity-impulsivity-attention problems before the age of 10. We used a sample of 186 adult men sentenced to prison in Sweden for 4 years or more for violent, nonsexual crimes. The mean age was 30.7( SD = 9.4). The results showed that a combination of childhood HIA problems and CP was typical for adult psychopathic offenders. They were four times more likely than chance to have had a combination of HIA problems and CP during childhood and only one-fifth as likely than chance to have had neither problem. Nonpsychopathic offenders, on the other hand, were five times more likely than chance to have had neither problem and only one-quarter as likely than chance to have had both problems.     

The effects of focal and global attentional systems on spatial biases

The background page on which a stimulus is presented can influence the allocation of attention to that stimulus. The purpose of this study was to learn if there are hemispheric asymmetries in how background distraction affects attentional processing. Asymmetries were investigated by having right eye dominant subjects perform line bisections and manipulating the side of background distraction (right versus left), the eye of regard (right versus left), and the type of attention allocated (focal versus global). Overall subjects bisected lines to the left of center (pseudoneglect) and when viewing with the right eye (versus left) deviated more to the left. Subjects had more background distraction when viewing symbol than solid lines. Although overall, bias did not differ with the side of background distraction or the line being on one side or the other, when subjects viewed symbol, but not solid lines, this leftward bias was increased when the line was displaced to the right, thereby increasing the size of the left sided background. These findings suggest that when engaging the left hemisphere by using focused attention and placing the line on the right side, there is more distraction than when the right hemisphere is engaged.     

MODIFICATION OF SHUTTLE BOX TO IMPROVE RATE OF AVOIDANCE LEARNING IN RATS

W allgren , H. & S avolainen , S. Modification of shuttle-box to improve rate of avoidance learning in rats. Scand. J. Psychol ., 1962, 3 , 78–80.—Acquisition by rats of a conditioned avoidance response seems to be retarded in an ordinary shuttle-box by the necessity to re-enter the compartment where shocks have previously been received. To avoid this, a four-compartment box was introduced in which the animals can proceed in one direction. Rats were given either continuous trials until nine avoidance responses were made during 10 consecutive trials, or 30 trials per day until 27 correct responses were made during one session. With both methods of training, the rate of learning was approximately 40 per cent more rapid in the four-compartment box than in the ordinary shuttle-box.     

Post-traumatic stress disorder and hiring: The role of social media disclosures on stigma and hiring assessments of veterans

A significant percentage of veterans suffer from post-traumatic stress disorder (PTSD). Veterans are often directed to social media platforms to seek support during their transition to civilian life. However, social media platforms are increasingly used to aid in hiring decisions, and these platforms may make veterans’ PTSD more discoverable during the hiring process. Based on social identity theory and identity management theory, the integrated suspicion model, and the stigma literature, we conducted four studies that examine veterans’ PTSD disclosures on social media and the consequences in the hiring process. Study 1 suggests that 16%–34% of veterans included cues related to PTSD status on social media. Study 2, based on 290 upper-level business students, shows that veterans with PTSD were more stigmatized than veterans without PTSD, and stigmatization is associated with more suspicion and lower hiring-related ratings (of expected task performance, expected organizational citizenship behaviors (OCB), expected counterproductive work behaviors (CWB), and intention to interview). Study 3, based on 431 working professionals with hiring experience, further supports relationships from Study 2. Study 4, based on 298 working professionals, identifies peril (i.e., perceptions regarding danger) as an additional mediator for the effects of PTSD on hiring-related ratings. In sum, we identify and explore the identity management conundrum that social media disclosure poses for veterans with PTSD in the hiring process and discuss potential remedies and avenues for future research.     

Phonological representation and speech understanding with cochlear implants in deafened adults

In the present study cognitive performance in 15 deafened adult cochlear implant candidates was examined and related to level of speech understanding after 12 months of experience with the implant. The implant group performed on par with normal hearing controls in all cognitive tasks used in the study with one exception: Performance was significantly lower in cognitive tasks where use of a phonological representation of sound is a key task-demand. Observations of the implanted individuals’ level of speech understanding indicate that only those individuals who, pre-operatively, were in possession of phonological representations comparable to that of normal hearing could follow and understand a speaker that was out of sight. The results are discussed with respect to (a) deterioration in the phonological representation of sounds as a function of absence of external auditory stimulation, and (b) the role of cognitive factors in predicting success in speech understanding with the implant.
