Perfectionism, beliefs, and adjustment in dating relationships

Two studies examined the extent to which dimensions of perfectionism are associated with indices of relationship beliefs, behaviors, and dyadic adjustment. In Study 1, 69 students in dating relationships completed the Multidimensional Perfectionism Scale (MPS) and a multidimensional measure of relationship beliefs. In addition, partici-pants completed self-report measures of positive and negative relationship behaviors, and global measures of liking and loving. In Study 2, 91 students in dating relation-ships completed a battery of measures including the MPS and scales assessing perfec-tionism cognitions and perfectionistic self presentation. They also completed mea-sures of dyadic adjustment and limerence (i.e., intense, obsessive low with fears of rejection). Collectively, the findings indicated that individuals with high levels of self-oriented perfectionism and other-oriented perfectionism have stronger relationship beliefs in the areas of communication, trust, and support, suggesting that these perfec-tionists have high relationship standards in these particular areas. Although social prescribed perfectionism had little association with specific relationship beliefs, so-cially prescribed perfectionism was associated with a tendency to display destructive relationship responses (i.e., exit, neglect, and insensitivity), lower dyadic adjustment, and various aspects of limerence, including obsessive preoccupations and emotional dependence on the dating partner. Perfectionistic self-presentation and perfectionism cognitions were also linked with aspects of limerence. The results suggest that inter-personal aspects of perfectionism are associated with self-defeating tendencies in dating relationships.

Greater attention problems during childhood predict poorer executive functioning in late adolescence

Attention problems (behavior problems including inattention, disorganization, impulsivity, and hyperactivity) are widely thought to reflect deficits in executive functions (EFs). However, it is unclear whether attention problems differentially relate to distinct EFs and how developmental stability and change predict levels of EFs in late adolescence. We investigated, in an unselected sample, how teacher-rated attention problems from ages 7 to 14 years related to three correlated but separable EFs, measured as latent variables at age 17. Attention problems at all ages significantly predicted later levels of response inhibition and working memory updating, and to some extent set shifting; the relation to inhibiting was stronger than the relations to the other EFs or IQ. Growth models indicated that attention problems were quite stable in this age range, and it was the initial levels of problems, rather than their changes across time, that predicted later EFs. These results support the hypothesis that attention problems primarily reflect difficulties with response inhibition.     

Dimensions of Perfectionism and Self-worth Contingencies in Depression

The current study investigated the role of contingent self-worth in perfectionism and depression. It was hypothesized that perfectionism is associated with depression because perfectionists base their self-worth on being successful and on the need to be actively working toward their goals. A sample of 170 female university students completed measures of conditional self-worth, perfectionism traits, perfectionism cognitions, and depressive symptoms. Structural equation modeling revealed that a factor interpreted as Evaluative Concerns Perfectionism was associated strongly with contingent self-worth, which was, in turn, related to depressive symptomatology. In addition, contingent self-worth mediated the association between perfectionism cognitions and depression. Other analyses revealed that measures of self-oriented perfectionism that are often viewed as highly similar actually differed in terms of their associations with contingent self-worth. The theoretical and practical implications of the associations between perfectionism and contingent self-worth are discussed.     

The role of binaural and fundamental frequency difference cues in the identification of concurrently presented vowels

The relative importance of voice pitch and interaural difference cues in facilitating the recognition of both of two concurrently presented synthetic vowels was measured. The interaural difference cues used were an interaural time difference (400 μsec ITD), two magnitudes of interaural level difference (15 dB and infinite ILD), and a combination of ITD and ILD (400 μsec plus 15 dB). The results are analysed separately for those cases where both vowels are identical and those where they are different. When the two vowels are different, a voice pitch difference of one semitone is found to improve the percentage of correct reports of both vowels by 35.8% on average. However, the use of interaural difference cues results in an improvement of 11.5% on average when there is a voice pitch difference of one semitone, but only a non-significant 0.1% when there is no voice pitch difference. When the two vowels are identical, imposition of either a voice pitch difference or binaural difference reduces performance, in a subtractive manner. It is argued that the smaller size of the interaural difference effect is not due to a “ceiling effect” but is characteristic of the relative importance of the two kinds of cues in this type of experiment. The possibility that the improvement due to interaural difference cues may in fact be due to monaural processing is discussed. A control experiment is reported for the ITD condition, which suggests binaural processing does occur for this condition. However, it is not certain whether the improvement in the ILD condition is due to binaural processing or use of the improvement in signal-to-noise ratio for a single vowel at each ear.

Structure and Etiology of Co-occurring Internalizing and Externalizing Disorders in Adolescents

Several studies suggest that a two-factor model positing internalizing and externalizing factors explains the interrelationships among psychiatric disorders. However, it is unclear whether the covariation between internalizing and externalizing disorders is due to common genetic or environmental influences. We examined whether a model positing two latent factors, internalizing and externalizing, explained the interrelationships among six psychiatric disorders (major depressive disorder, generalized anxiety disorder, separation anxiety disorder, attention-deficit/hyperactivity disorder, oppositional defiant disorder, and conduct disorder) in adolescents, and whether there are common genetic and environmental influences on internalizing and externalizing latent factors. Multivariate behavior genetic analyses of data from 1162 twin pairs and 426 siblings ascertained from the general population via the Colorado Center for Antisocial Drug Dependence (CADD) were conducted. We found support for a model positing two latent factors (internalizing and externalizing). These factors were moderately heritable and influenced by significant common genetic and nonshared environmental influences. These findings suggest that co-occurrence of internalizing and externalizing psychopathology in adolescents results from both genetic and environmental influences.
