In collaboration, group knowledge awareness (i.e. being informed about the partners’ knowledge) is used to effectively communicate and to efficiently coordinate interaction. Computer-mediated collaboration impairs the establishment of group knowledge awareness. Technological support for group knowledge awareness can compensate for this shortcoming and is realized in a group knowledge awareness ...

PURPOSE/OBJECTIVES To assess the degree to which postsurgical adjustment in patients with breast cancer and their partners depends on the nature of the patient-partner dyad relationship. DESIGN Secondary data analysis from a randomized controlled trial. SETTING Three cancer centers and one suburban community hospital in New York. SAMPLE 205 patient-partner dyads (112 intimate-partner, 58 ...

a r t i c l e i n f o Keywords: Parenting stress Family economic strengthening AIDS-orphans Caregivers Randomized clinical trial Uganda This study examines the impact of a family economic strengthening intervention on parenting stress among care-givers of AIDS-orphaned children in Uganda. The study uses data from a 4-year (2008–2012) NIMH randomized clinical trial for AIDS-orphaned children kno...

This study examined whether the grouping of people into meaningful social scenes (e.g., two people having a chat) impacts the basic perceptual analysis of each partaking individual. To explore this issue, we measured neural activity using functional magnetic resonance imaging (fMRI) while participants sex-categorized congruent as well as incongruent person dyads (i.e., two people interacting in...

The objective of this study was to observe parent-child interactions in tiendas, limited assortment food stores catering to Latinos in the United States, and to examine the extent to which child involvement influenced these interactions and their purchase outcomes. Two confederates, one posing as a tienda employee and one posing as a customer, observed the entire shopping trip of 100 Latino par...

Objective: This study addresses a practical homeland security issue of considerable current concern: In a situation in which the opportunity exists to question or interview concurrently two or more suspects, how does one determine truth or deception at a social level? Background: Recent world events have led to an increased emphasis on the capacity to detect deception, especially in military, s...

This thesis investigates the cognitive processes and representations underlying human judgment in a multiple-cue judgment task. Several recent models assume that people have several qualitatively distinct and competing levels of knowledge representations (Ashby, The most successful cognitive models in categorization and multiple-cue judgment are, respectively, exemplar-based models and rule-bas...

When humans perform tasks together, they may reach a higher performance in comparison to the best member of a group (i.e., a collective benefit). Earlier research showed that interindividual performance similarities predict collective benefits for several joint tasks. Yet, researchers did not test whether this is the case for joint visuospatial tasks. Also, researchers did not investigate wheth...

We incorporated radio-telemetry data with genetic analysis of bat-eared foxes (Otocyon megalotis) from individuals in 32 different groups to examine relatedness and spatial organization in two populations in South Africa that differed in density, home-range sizes, and group sizes. Kin clustering occurred only for female dyads in the high-density population. Relatedness was negatively correlated...
