Attention Time-sharing

Multiple resource model of attention and W/INDEX Models attention as a collection of separable processing resources. W/INDEX is a computer model of workload that adopts the multiple-resource construct and accounts for resource conflict from separable processing resources Time sharing ability Automatic processing... 

An approach sometimes used in a variety of measurement contexts incorporates a dual-task or divided attention scenario that is designed to require use of attention resources in two different simultaneously executed tasks (e.g., Wickens, 1984). For example, visual tracking (primary task) accuracy and speed of response to an embedded visual stimulus (secondary task) can be measured. Details of the potential time-sharing possibihties at play are quite complex (Schneider and Shiffirin, 1977 Shiffirin and Schneider, 1977).

In summary, implementation quality and the overall success of prevention initiatives are affected by the attitudes and beliefs of students, teachers, school administrators, mental health personnel, parents, and members of the broader community who make school-related decisions. For prevention efforts to be successful, these key stakeholders must believe that a need exists and view change as a necessary goal. They also must see the problem as preventable and the intervention as effective. This shared vision can provide the necessary initial impetus to ensure that the intervention will become a priority and be allotted adequate attention, time, and financial resources. 

We end this section by examining a few commonly used verb tense-voice combinations in move 2 (table 13.5). Present perfect is commonly used to describe preliminary work (done in the past) present tense is commonly used to share preliminary findings (believed to be true over time). Active voice is also common. Note that because authors want to call attention to their own promising results in this move, personal pronouns such as we or our are often used. 

Detonation in gases has been mote thoroughly investigated than in condensed phases, and continues to receive the major share of attention. In a broad sense the chain of events is the same in both cases (Ref 7, p 2), but in gases is spread out in both space and time, being therefore more easily observed... 

Remarkably, this publication attracted little attention and generated little response at the time and for several years afterwards, nor were any priority claims made. The macrocyclic iterative variant non-skid-chain like molecule also mentioned in reference [1] shares this fate to the present day.
