Effects of low survivability cues and participant sex on physiological and behavioral responses to sexual stimuli

According to life history theory, environmental cues indicating that one's future survivability is low increase reproductive effort. This suggests that exposure to low survivability cues will increase people's preparedness to engage in sex. However, according to sexual selection theory and parental investment theory, evolutionary pressures favored a more conservative sexual strategy among women compared to men. We therefore hypothesized that men, but not women, would respond to low survivability cues with increased sexual preparedness. Accordingly, both subliminal and supraliminal death primes (as compared with control primes) led men, but not women, to exhibit increased physiological arousal in response to sexual images (Study 1), and stronger approach-oriented behavioral responses to sexual images (Study 2). Theoretical implications for life history theory are discussed.     

Seeing with sound? exploring different characteristics of a visual-to-auditory sensory substitution device

Sensory substitution devices convert live visual images into auditory signals, for example with a web camera (to record the images), a computer (to perform the conversion) and headphones (to listen to the sounds). In a series of three experiments, the performance of one such device ('The vOICe') was assessed under various conditions on blindfolded sighted participants. The main task that we used involved identifying and locating objects placed on a table by holding a webcam (like a flashlight) or wearing it on the head (like a miner's light). Identifying objects on a table was easier with a hand-held device, but locating the objects was easier with a head-mounted device. Brightness converted into loudness was less effective than the reverse contrast (dark being loud), suggesting that performance under these conditions (natural indoor lighting, novice users) is related more to the properties of the auditory signal (ie the amount of noise in it) than the cross-modal association between loudness and brightness. Individual differences in musical memory (detecting pitch changes in two sequences of notes) was related to the time taken to identify or recognise objects, but individual differences in self-reported vividness of visual imagery did not reliably predict performance across the experiments. In general, the results suggest that the auditory characteristics of the device may be more important for initial learning than visual associations.     

Relational Aggression in Women during Emerging Adulthood: A Social Process Model

Two studies investigated potential mediators of the association between relational victimization and relational aggression. Self-report measures of aggressive behavior among peers, exclusivity, hostile attribution biases, and borderline personality disorder (BPD) symptoms were collected. In study 1, participants were 180 female emerging adults (M = 18.82, SD = 1.18). Both exclusivity and hostile attribution biases for relational provocations were found to partially mediate the association between relational victimization and relational aggression. In study 2, participants were 54 female emerging adults (M = 19.16, SD = 1.11). Symptoms of BPD were not found to mediate the association between relational victimization and relational aggression, yet unique associations with relational aggression were observed. The results add to recent research guided by a social process model in which links between victimization and aggression are more clearly understood. Copyright © 2011 John Wiley & Sons, Ltd.     

The Role of Paternal Age in the Prediction of Offspring Intelligence

Recent evidence suggests that paternal age at birth influences myriad developmental outcomes among children, but few studies have examined the possibility for father's age to influence children's intellectual development among a sample of high-risk families. The authors use data from the Fragile Families and Child Wellbeing Study to examine the association between paternal age at birth among 480 male and 449 female children's verbal IQ scores, as assessed with a version of the Peabody Picture Vocabulary Test at 9 years old. The nonlinear association between paternal age and children's verbal intelligence was also examined. Paternal age at birth appears to have a marginally significant nonlinear relationship with male children's verbal IQ scores, despite controlling for a number of possible confounders associated with both young and advanced paternal age.     

Ostracism,resources, and the perception of human motion

Is perception of human motion affected by psychosocial resources? According to the Resources and Perception Model, perception is jointly affected by subjective threat and psychosocial resources that buffer threat. Two experiments tested whether social threat (i.e., ostracism) and psychosocial resources affect perception of human motion. Observers attempted to identify human movement in ambiguous point‐light displays after being ostracized or not ostracized. Additionally, trait resources (self‐esteem plus social support) were measured (Studies 1 and 2), and self‐affirmation was manipulated (Study 2). Study 1 showed that ostracism reduced sensitivity for detecting human motion but not among people with ample trait resources. Study 2 replicated this ostracism‐by‐trait resources interaction. It also showed that self‐affirmation improved human motion perception for all included participants but only benefited ostracized participants with ample trait resources. These studies show that a basic visual skill—detecting human motion—is jointly affected by social threats and psychosocial resources.     

Relations Among Perceived Control Over Anxiety-Related Events,Worry, and Generalized Anxiety Disorder in a Sample of Adolescents

This study examined the associations among perceived control over anxiety-related events, worry, and both symptoms and diagnoses of generalized anxiety disorder (GAD). The sample was comprised of 140 adolescents (60 girls) between the ages of 10 and 17 years (M _age  = 14.6 years; SD = 2.25) recruited from the general community. Findings were consistent with hypotheses. Self-reported perceived control over anxiety-related events related negatively to worry as well as symptoms and diagnoses of GAD even after accounting for variance associated with age, gender, and negative affectivity. Results are discussed in terms of the theoretical implications that perceived control over anxiety-related events may have for understanding GAD symptomatology among youth.     

Parental Overprotection,Perceived Child Vulnerability,and Parenting Stress: A Cross-Illness Comparison

The current study sought to investigate differences in parenting capacity variables across four disease groups. Parents (N = 425), the majority of whom were mothers, of children with either cancer, asthma, Type 1 diabetes, or cystic fibrosis, completed measures of parental overprotection, perceived child vulnerability, and parenting stress. After controlling for significant demographic variables, parents of children with cystic fibrosis and asthma reported higher perceived child vulnerability than parents of children with either diabetes or cancer, while parents of children with asthma and diabetes reported higher parenting stress than parents of children with cancer or cystic fibrosis. No differences between disease groups were found for parental overprotection. The current study provides support for an illness-specific approach to understanding parenting capacity variables in the context of childhood chronic illnesses.     

The Body Stripped Down

Abstract— According to terror management theory, cultural beliefs and standards provide protection from fears associated with mortality by convincing individuals that their existence matters more than that of any mere mortal animal. The body threatens the efficacy of such mechanisms by reminding us that we are animals nonetheless, and therefore fated to death. I present research demonstrating that existential concerns contribute to uneasiness with the body, especially regarding sex, and also to pervasive concerns with how the body measures up to cultural standards, most obviously regarding women's appearance. These findings show that in effort to defend against threats associated with the body's physicality, people may deny themselves pleasure and endanger their health.     

The role of depression symptoms in dialysis withdrawal.

Among end-stage renal disease (ESRD) patients on hemodialysis, death from withdrawal from life-sustaining dialysis is increasingly common. The present study's objective was to examine depression as a potential risk factor for hemodialysis withdrawal. Two hundred forty ESRD hemodialysis (133 male and 107 female) patients were followed for an average of 4 years after depression symptom assessment. Of these, 18% withdrew from dialysis. Using multivariate survival analysis and after controlling for the effects of age (p < .001) and clinical variables, the authors found that level of depression symptoms was a unique and significant predictive risk factor for the subsequent decision to withdraw from dialysis (p < .05). The potential impact that depression may have on the decision to withdraw from hemodialysis should be considered by health care providers, patient families, and patients.     

Self‐sacrifice as self‐defence: Mortality salience increases efforts to affirm a symbolic immortal self at the expense of the physical self

The increasing occurrence of suicide bombing attacks highlights a question that has received little direct empirical attention in social psychology. Why are people willing to sacrifice their lives to advance an ideological agenda? The current research suggests that willingness to self‐sacrifice reflects efforts to manage death awareness by investing in a symbolic identity that provides some form of immortality. If willingness to self‐sacrifice is a response to death awareness then increasing the salience of death thoughts should lead to an increase in willingness to self‐sacrifice for a death‐transcending symbolic identity (e.g. one's nation). Further, if self‐sacrifice after mortality salience (MS) is a striving for symbolic immortality then having participants imagine an alternative way to transcend death should moderate this effect. Support for these hypotheses was found as MS increased willingness of British participants to self‐sacrifice for England, but only when an alternative route to symbolic immortality was not provided. Implications are briefly discussed. Copyright © 2007 John Wiley & Sons, Ltd.
