The Face-to-Face Light Detection Paradigm: A New Methodology for Investigating Visuospatial Attention Across Different Face Regions in Live Face-to-Face Communication Settings.

We introduce a novel paradigm for studying the cognitive processes used by listeners within interactive settings. This paradigm places the talker and the listener in the same physical space, creating opportunities for investigations of attention and comprehension processes taking place during interactive discourse situations. An experiment was conducted to compare results from previous research using videotaped stimuli to those obtained within the live face-to-face task paradigm.

Lateralization of visuospatial attention across face regions varies with emotional prosody.

It is well-established that linguistic processing is primarily a left-hemisphere activity, while emotional prosody processing is lateralized to the right hemisphere. Does attention, directed at different regions of the talker's face, reflect this pattern of lateralization? We investigated visuospatial attention across a talker's face with a dual-task paradigm, using dot detection and language comprehension measures. A static image of a talker was shown while participants listened to speeches spoken in two prosodic formats, emotional or neutral.

Lifespan differences in the social networks of prison inmates.

Socioemotional Selectivity Theory (SST) (Carstensen, 1992, 1993) accounts for lifespan changes in human social networks and for the motivations which underlie those changes. SST is applied in this research with 256 prison inmates and non-inmates, ages 18-84, from Mississippi, Kansas, and New Mexico. Two research questions sought to identify (a) whether inmate networks change in size, and (b) whether overall closeness within an inmate's network changes over the adult years.

Vulnerability of older adults to deception in prison and nonprison contexts.

Media reports frequently depict older adults as victims of deception. The public perceives these stories as particularly salient because older adults are seen as fragile victims taken advantage of because of trusting behaviors. This developmental investigation of deception detection examines older and younger adults interacting in 2 contexts, prison and the "free world," to discover whether older adults are vulnerable to deception.
