A Relevance Constraint on Composition

Whether certain objects compose a whole at a given time does not seem to depend on anything other than the character of those objects and the relations between them. This observation suggests a far-reaching constraint on theories of composition. One version of the constraint has been explicitly adopted by van Inwagen and rules out his own answer to the composition question. The constraint also rules out the other well-known moderate answers that have so far been proposed.     

Parentification,Stress, and Problem Behavior of Adolescents who have a Parent with Mental Health Problems

When adolescents live with a parent with mental illness, they often partly take over the parental role. Little is known about the consequences of this so‐called parentification on the adolescents' internalizing and externalizing problems. This survey study examined this effect cross‐sectionally and longitudinally in a sample of 118 adolescents living with a parent suffering from mental health problems. In addition, the study examined a possible indirect effect via perceived stress. Path analyses were used to examine the direct associations between parentification and problem behavior as well as the indirect relations via perceived stress. The results showed that parentification was associated with both internalizing and externalizing problems cross‐sectionally, but it predicted only internalizing problems 1 year later. An indirect effect of parentification on adolescent internalizing and externalizing problems via perceived stress was found, albeit only cross‐sectionally. These findings imply that parentification can be stressful for adolescents who live with a parent with mental health problems, and that a greater awareness of parentification is needed to prevent adolescents from developing internalizing problems.     

Understanding the Relationship between Religiosity and Caregiver–Adolescent Communication About Sex within African-American Families

Caregiver–adolescent communication about sex plays a critical role in the sexual socialization of youth. Many caregivers, however, do not engage their youth in such conversations, potentially placing them at risk for negative sexual health outcomes. Lack of caregiver–adolescent communication about sex may be particularly harmful for rural African American youth, as they often report early sex initiation and are disproportionately impacted by STIs. Moreover, sexual communication may be particularly challenging for families with strong religious backgrounds, potentially affecting the occurrence and breadth of topics covered during communication. Study aims were to: determine whether there was a relationship between caregiver religiosity and type of topics covered during communication about sex (e.g., general sexual health vs. positive aspects of sexuality) among 435 caregivers of early adolescent, African American youth; and if so, identify factors that might explain how religiosity affects communication about sex. Results indicated that caregiver religiosity was positively associated with communication about general, but not positive aspects of sexuality for caregivers of males. Attitudes towards communication about sex and open communication style mediated the relationship. There was no association between religiosity and communication about sex for caregivers of females. The findings from this study could provide a base to better understand and support the sexual socialization process within religious, African American families.     

Difference scores: A caveat illustrated with neuropsychological measures

Relationships among preferred minus non-preferred hand difference scores from four neuropsychological sensorimotor tests were evaluated in Community (N= 121), Prison Inmate (N = 350), and Psychiatric Inpatient (N = 398) samples. Across the three samples, the average absolute off-diagonal correlations among the four difference scores ranged from .07 to .13, and the squared multiple correlations (used to predict any difference score from the other three) did not exceed .07. Based on the determinant of the correlation matrix (i.e., |R|), the null hypothesis of complete independence was rejected in only the Prison Inmate sample (p < .001), however, departure from the null hypothesis was negligible (i.e., |R| = .94, expected value under the null = .98). Preferred/non-preferred hand ratio scores were very highly correlated with the difference scores and consequently analyses of the ratio scores yielded results that were comparable to those obtained for the difference scores. Results indicate that the four difference scores or four ratio scores measure little in common and therefore cannot corroborate each other. In general, it would be prudent to exercise considerable caution when using difference scores or ratio scores obtained from non-independent measures, either singly or in combination.     

Why envy outperforms admiration

Four studies tested the hypothesis that the emotion of benign envy, but not the emotions of admiration or malicious envy, motivates people to improve themselves. Studies 1 to 3 found that only benign envy was related to the motivation to study more (Study 1) and to actual performance on the Remote Associates Task (which measures intelligence and creativity; Studies 2 and 3). Study 4 found that an upward social comparison triggered benign envy and subsequent better performance only when people thought self-improvement was attainable. When participants thought self-improvement was hard, an upward social comparison led to more admiration and no motivation to do better. Implications of these findings for theories of social emotions such as envy, social comparisons, and for understanding the influence of role models are discussed.     

Does cognitive flexibility training enhance subjective mental functioning in healthy older adults?

Declining cognitive abilities in older adults can contribute to significant changes in socioemotional health and substantially reduce their perception of well-being. Whereas much attention has been dedicated to creating cognitive training programs to improve cognitive health in old age, there is little emphasis on the consequences of such interventions for subjective mental functioning. We created a randomized controlled trial in which we evaluated the effects of an adaptive computerized cognitive flexibility training. Healthy older adults (60–80 years old) were assigned to one of three conditions (frequent or infrequent switching or active control group) and performed 58 half-hour sessions within a period of 12 weeks. We measured effects on subjective cognitive failures and executive dysfunctioning, everyday functioning, depressive symptoms, anxiety, and quality of life, before, and after training. Additionally, participants’ proxies rated their cognitive failures and executive dysfunctioning. Subjective cognitive failures and executive dysfunctioning improved 4 weeks posttraining in all groups, although effect sizes were low (?_p² = .058 and .079, respectively) and there were no differences between groups (all p’s > .38). No significant changes in subjective reports were seen directly after training, which was the case in all groups. Proxies did not report any functional changes over time, yet their evaluations were significantly more favorable than those of the participants, both pretraining (p < .0005) and posttraining (p = .004). Although we found no evidence of improvement on subjective mental functioning, we adduce several factors that encourage further research into the effects of computerized cognitive training on subjective performance.     

Interapy: treatment of post-traumatic stress via the internet

This paper describes the theoretical background and procedures (including psycho-education, screening, treatment protocol and outcome measurement) involved in a protocol-driven internet treatment of post-traumatic stress and grief in a group of people who have suffered from mild to relatively severe trauma. The paper examines the results of 3 outcome and process studies, which were carried out initially in a student population and subsequently in the general population of highly traumatized people. In the latter study, participants in the experimental condition (n = 69) improved significantly more than participants in the waiting list control condition (n = 32), with respect to trauma-related symptoms and general psychopathology. The effect sizes were large. More than 50% of the participants treated showed reliable change and clinically significant improvement after treatment for avoidance and depression. Treatment proved most beneficial for participants who had suffered from intentional trauma and those who had not previously discussed the traumatic events with significant others. Content analysis of the publications indicates a remarkable increase in cognitive coping during treatment. The possibilities for future research into internet-driven treatment of post-traumatic stress symptomatology are discussed, including the proposal to study the effects of sending a final written letter to a significant other person.     

Granting forgiveness or harboring grudges: implications for emotion, physiology, and health

Interpersonal offenses frequently mar relationships. Theorists have argued that the responses victims adopt toward their offenders have ramifications not only for their cognition, but also for their emotion, physiology, and health. This study examined the immediate emotional and physiological effects that occurred when participants (35 females, 36 males) rehearsed hurtful memories and nursed grudges (i.e., were unforgiving) compared with when they cultivated empathic perspective taking and imagined granting forgiveness (i.e., were forgiving) toward real-life offenders. Unforgiving thoughts prompted more aversive emotion, and significantly higher corrugator (brow) electromyogram (EMG), skin conductance, heart rate, and blood pressure changes from baseline. The EMG, skin conductance, and heart rate effects persisted after imagery into the recovery periods. Forgiving thoughts prompted greater perceived control and comparatively lower physiological stress responses. The results dovetail with the psychophysiology literature and suggest possible mechanisms through which chronic unforgiving responses may erode health whereas forgiving responses may enhance it.     

The explanatory role of rumours in the reciprocal relationship between organizational change communication and job insecurity: a within-person approach

The current study highlights rumours as an explanation of the reciprocal relationship between perceived organizational change communication and job insecurity. First, we predict that perceiving insufficient organizational change communication may result in rumours, which in turn may shape job insecurity perceptions. Second, we propose that rumours may also mediate the relationship between job insecurity and perceiving insufficient organizational change communication. To test the hypotheses, a multilevel approach was used, in which three measurements were nested within 1994 employees. This enabled us to probe within-person processes, while controlling for possible between-person variation. The results demonstrated a negative reciprocal relationship between perceived organizational change communication and job insecurity. Additionally, rumours mediated both the negative relationship between perceived organizational change communication and subsequent job insecurity, and the negative relationship between job insecurity and subsequent perceived organizational change communication. This study contributes to the literature on job insecurity by offering initial evidence on the relationship between job insecurity and rumours, and by highlighting rumours as a process through which perceived organizational change communication and job insecurity may mutually affect each other.
