Combined eyetracking and keystroke-logging methods for studying cognitive processes in text production

Writers typically spend a certain proportion of time looking back over the text that they have written. This is likely to serve a number of different functions, which are currently poorly understood. In this article, we present two systems, ScriptLog+TimeLine and EyeWrite, that adopt different and complementary approaches to exploring this activity by collecting and analyzing combined eye movement and keystroke data from writers composing extended texts. ScriptLog+TimeLine is a system that is based on an existing keystroke-logging program and uses heuristic, pattern-matching methods to identify reading episodes within eye movement data. EyeWrite is an integrated editor and analysis system that permits identification of the words that the writer fixates and their location within the developing text. We demonstrate how the methods instantiated within these systems can be used to make sense of the large amount of data generated by eyetracking and keystroke logging in order to inform understanding of the cognitive processes that underlie written text production.     

Children and aging: attitudes, differentiation ability, and quantity and quality of contact

The attitudes and age differentiation ability of forty-seven 3- to 5-year-old children toward pictures of older and younger people were assessed. In addition, cognitive performance on a seriation task as well as the quantity and quality of each child's contact with adults over 60 years of age were measured. Chi squares were performed by sex and age of stimulus photograph on the attitudinal questions. One of the chi squares reached significance on the age comparison and two on the sex comparison. In addition, sign tests were used to assess the direction of the trends on the questions, and both age and sex trends were significant at the .05 level with children being more likely to choose pictures of younger rather than older models and female rather than male models. Ability to correctly order pictures by age was significantly related (r = .53, p less than .001) to the seriation ordering task. Four of the 18 correlations between contact and attitudinal variables were significant and negative.     

Relationships between patients' perceived improvement and their evaluations of treatment components in a behaviorally-oriented psychiatric inpatient unit

Patients on a behaviorally-oriented inpatient psychiatric unit were asked to rate their perceptions of treatment outcome and the value of 16 program components in producing that outcome. Significant correlations were found between perceived outcome and positive evaluations of the overall behavioral treatment plan, individual meetings with nursing staff, individual meetings with team psychologists, assertion group training, and daily group therapy. Patients perceived individual meetings with the nursing staff to be the single most valuable program component among those related to favorable outcome. Implications for the increased utilization of nursing staff during a time of dwindling resources for mental health are discussed.     

Cockpit-cabin communication: I. A tale of two cultures

Several dramatic accidents have emphasized certain deficiencies in cockpit-cabin coordination and communication. There are historical, organizational, environmental, psychosocial, and regulatory factors that have led to misunderstandings, problematic attitudes, and suboptimal interactions between the cockpit and cabin crews. Our research indicates the basic problem is that these two crews represent two distinct and separate cultures and that this separation serves to inhibit satisfactory teamwork. A survey was conducted at two airlines to measure attitudes of cockpit and cabin crews concerning the effectiveness of their communications. This article includes recommendations for the improvement of communications across the two cultures.     

Measuring flicker thresholds in the budgerigar

Pigeons were trained to discriminate apparent movement and real movement in visual displays showing horizontal movement. Generalization testing on the dimension of directional movement yielded gradients that sloped as movement changed from horizontal to vertical. Evidence of generalization between apparent movement and real movement was found in equivalent response rates to training displays of either type. Extremely low response rates to training displays pulsating but showing no movement eliminated flicker as the basis of the discrimination.
