Researchers from multiple fields have sought to understand how sex moderates human social behavior. While over 50 years of research has revealed differences in cooperation behavior of males and females, the underlying neural correlates of these sex differences have not been explained. A missing and fundamental element of this puzzle is an understanding of how the sex composition of an interacti...

The purpose of this study was to determine whether the perceived sensory dissonance of pairs of pure tones (PT dyads) or pairs of harmonic complex tones (HC dyads) is altered due to sensorineural hearing loss. Four normal-hearing (NH) and four hearing-impaired (HI) listeners judged the sensory dissonance of PT dyads geometrically centered at 500 and 2000 Hz, and of HC dyads with fundamental fre...

Two hundred eight parent–college student dyads (total N = 416) participated in the current study, which examined the link between goal agreement and perceived conflict within their relationships. Undergraduate participants (91 male, 117 female) completed a demographic form, a 65 items goal measure, and a measure of parental conflict. Parents (98 fathers, 110 mothers) were asked to rate the impo...

The role of dyadic trade dependence in reducing conflict has been a subject of some dispute in the recent literature. Liberals have presented strong evidence that a higher level of trade dependence leads to lower probabilities of dyadic disputes, while an equally compelling literature has generated evidence that elevated levels of trade dependence generally increase the likelihood of disputes, ...

Background To decrease the readmission rate of heart failure (HF) patients, patients and their caregivers (CGs) should participate in symptoms assessment. This study aimed to assess the agreement between HF patients and their CGs on symptoms assessment. Methods Using a correlational design, 100 HF patients with their CGs (100 dyads) were recruited from Department of Cardiology, Iranshahr, dur...

PURPOSE To examine the psychometric properties of the Injection Pen Assessment Questionnaire (IPAQ) including the following: 1) item and scale characteristics (e.g., frequencies, item distributions, and factor structure), 2) reliability, and 3) validity. METHODS Focus groups and one-on-one dyad interviews guided the development of the IPAQ. The IPAQ was subsequently tested in 136 parent-child...

It is well known that perceptual and conceptual fluency can influence episodic memory judgments. Here, the authors asked whether fluency arising from the motor system also impacts recognition memory. Past research has shown that the perception of letters automatically activates motor programs of typing actions in skilled typists. In this study, expert typists made more false recognition errors ...

OBJECTIVE The objective of this study was to examine associations of mother and infant salivary cortisol, measured three times over the course of a day, and assess whether these varied by breastfeeding status. METHODS We conducted a cross-sectional study of 54 mothers and their infants aged 4-11 months. Mothers collected their own saliva and that of their infants upon awakening, 30min after w...
