Electrophysiological indices of brain activity to "the" in discourse

In a first experiment, we recorded event-related-potentials (ERPs) to "the" followed by meaningful words (Story) versus "the" followed by nonsense syllables (Nonse). Left and right lateral anterior positivities (LAPs) were seen from the onset of "the" up to 200 ms in both conditions. Later than 200 ms following the onset of "the", the left and right LAPs continued for "the" in the Story, but were replaced by a negativity in the Nonse Condition. In a second experiment, ERPs were recorded to "the" in the Story and Nonse contexts mixed together under two different task instructions (attend to the auditory stimuli versus ignore the auditory stimuli). The same pattern of findings as Experiment 1 were observed for the Story and Nonse contexts when the participants attended to the auditory stimuli. Ignoring the auditory stimuli led to an attenuation of the right LAP, supporting the hypothesis that it is an index of discourse processing.     

Dysfunctional isolation in the elderly: Increasing marital and family closeness through improved communication

Unique developmental crises in old age may lead to social withdrawal that negatively affects the individual and his/her marital and family relationships. Without an awareness of these aging dynamics, the therapist can inadvertently perpetuate these distancing behaviors which can exacerbate marital and family conflict. This paper discusses certain developmental crises which can result in increased isolation for the older adult, and suggests therapeutic interventions to facilitate increased closeness among family members.
