Journal article (peer-reviewed)abstract
- Two experiments addressed the influence of secondary task performance at encoding on recall of different features of subject‐performed tasks (SPTs) involving objects (e.g., turn the wallet). In Experiment 1, memory for verbs and colors of objects was assessed, with object names serving as cues. In Experiment 2, object and color memory were assessed, with verbs serving as cues. Results from both experiments indicated a greater deterioration of memory performance under divided attention for verbal features than for colors. In addition, intention to remember did not affect performance for any feature in either experiment. The overall pattern of outcome is discussed relative to the view that encoding of verbal features of SPTs is more attention‐demanding than encoding of physical task features, such as color.

Cognitive and neuropsychological aspects of age-associated memory dysfunction
- 1991
-
Doctoral thesis (other academic/artistic)abstract
- Memory dysfunction is common in association with the course of normal aging. Memory dysfunction is also obligatory in age-associated neurological disorders, such as Alzheimer’s disease. However, despite the ubiquitousness of age-related memory decline, several basic questions regarding this entity remain unanswered. The present investigation addressed two such questions: (1) Can individuals suffering from memory dysfunction due to aging and amnesia due to Alzheimer’s disease improve memory performance if contextual support is provided at the time of acquisition of to-be- remembered material or reproduction of to-be-remembered material? (2) Are memory deficits observed in ‘younger’ older adults similar to the deficits observed in ‘older’ elderly subjects, Alzheimer’s disease, and memory dysfunction in younger subjects?The outcome of this investigation suggests an affirmative answer to the first question. Given appropriate support at encoding and retrieval, even densely amnesic patients can improve their memory performance. As to the second question, a more complex pattern emerges. When attentional demands are varied, subjects of varying ages perform qualitatively similar. However, when semantic aspects of the to-be- remembered material are manipulated, age-associated qualitative differences are observed. These qualitative differences show up between older and younger adults, as well as between ‘younger’ and ‘older’ elderly subjects.

The dual-conception view reexamined : attentional demands and the encoding of verbal and physical information in action events
- 1994

Journal article (peer-reviewed)abstract
- In two experiments the influence of attentional demands at encoding on recall of different features of subject-performed tasks (SPTs) was studied. In Experiment 1, memory of verbs and colors of objects was tested, with object names serving as cues. In Experiment 2, object and color memory were tested, with verbs serving as cues. Results from both experiments indicated that SPTs were affected by divided attention at encoding. In contrast to previous research, verbal and physical properties of SPTs were not differently affected by the requirements of dual-task performance (i.e., the combination of an SPT task and a secondary task). The results are discussed in terms of the nature of the secondary task.
