Common factors in the enhancement of dyadic coping

Stress and coping are important constructs in understanding the dynamics of close relationships. Couple therapy and marital distress prevention approaches have become increasingly focused on these variables to gain knowledge of how stress and coping may impact the quality and stability of close relationships. In this paper, we outline couple's coping enhancement training (CCET) and the coping-oriented couple's therapy (COCT); both, couple interventions derived from stress and coping research. We address specific features of each approach and report data on their efficacy and effectiveness. We also examine both the common and specific factors that may play a role in the effectiveness of these approaches.     

Changes in spinal excitability during dual task performance

ABSTRACT The authors investigated how the nervous system responds to dual task performance. Because dual tasking is associated with greater postural challenges, it was hypothesized that spinal excitability would be reduced when simultaneously performing 2 tasks. For this experiment, participants maintained a lying or standing posture with or without performing a concurrent cognitive task (i.e., reacting to an auditory tone). Spinal excitability was assessed by eliciting the soleus Hoffmann reflex (H-reflex). Results indicated that the H-reflex was 6.4 ± 2.3% smaller (p = .011) when dual compared to single tasking. The reduced H-reflex amplitude, indicating a depressed spinal excitability, when dual tasking is suggested to reflect a neural strategy that individuals adopt to maintain postural stability when cognitive resources are divided between 2 concurrent tasks.     

More than just a pretty face and a hot body: multiple cues in mate-choice

Mate preferences have been well studied in social and evolutionary psychology. In two studies (N = 490), using two different measurement techniques, we examined mate preferences for the body and the face in the context of other traits. Results replicated prior research on mate preferences across the sex of the participant and mating duration but clarified the nature of preferences for physical attractiveness. Generally, physical attractiveness was a necessity in short-term mating and for men and traits like kindness were a necessity in long-term mating and for women. Men wanted a short-term mate who had a good body, likely because that body advertises fertility whereas both sexes wanted a mate with a nice face for a long-term mate, which is likely because the face is a cue based on structural properties related to health. Sex and mating-duration differences on preferences for attractive faces and bodies were robust to differences in measurement technique.     

Identifying careless responses in survey data

When data are collected via anonymous Internet surveys, particularly under conditions of obligatory participation (such as with student samples), data quality can be a concern. However, little guidance exists in the published literature regarding techniques for detecting careless responses. Previously several potential approaches have been suggested for identifying careless respondents via indices computed from the data, yet almost no prior work has examined the relationships among these indicators or the types of data patterns identified by each. In 2 studies, we examined several methods for identifying careless responses, including (a) special items designed to detect careless response, (b) response consistency indices formed from responses to typical survey items, (c) multivariate outlier analysis, (d) response time, and (e) self-reported diligence. Results indicated that there are two distinct patterns of careless response (random and nonrandom) and that different indices are needed to identify these different response patterns. We also found that approximately 10%-12% of undergraduates completing a lengthy survey for course credit were identified as careless responders. In Study 2, we simulated data with known random response patterns to determine the efficacy of several indicators of careless response. We found that the nature of the data strongly influenced the efficacy of the indices to identify careless responses. Recommendations include using identified rather than anonymous responses, incorporating instructed response items before data collection, as well as computing consistency indices and multivariate outlier analysis to ensure high-quality data.

Ethnic differences in mother-infant language and gestural communications are associated with specific skills in infants

We examined gestural and verbal interactions in 226 mother-infant pairs from Mexican, Dominican, and African American backgrounds when infants were 14 months and 2 years of age, and related these interactions to infants' emerging skills. At both ages, dyads were video-recorded as they shared a wordless number book, a wordless emotion book, and beads and string. We coded mothers' and infants' gestures and language/vocalizations. Each maternal utterance was coded as referential (e.g. 'That's a bead') or regulatory (e.g. 'Put it there'). Mothers reported on infants' gestural, receptive, and productive vocabularies at 14 months, and infants were assessed on receptive language, expressive language, and action sequencing and imitation at 2 years of age. Mothers of the three ethnicities differed in their gesturing, distributions of the two types of language, and coupling of language and gestures. Mothers' ethnicity, language, and gestures were differentially associated with infants' 2-year skills. Mother-infant communicative interactions are foundational to infant learning and development, and ethnic differences in modes of early communication portend divergent pathways in the development of specific skills.
