ABSTRACT. Investigatory behavior with novel, inanimate objects by two groups of four juvenile greater bushbabies (Otolemur garnettii) was examined in the laboratory. Substantial investigatory behavior was shown by all subjects. In the first study, subjects showed interest in a wide variety of nonfood stimulus objects. In the second, subjects displayed sustained interest in and investigation of non-food stimulus objects over three sessions. Bushbabies showed preferences for larger, more manipulable objects and variations in total contact over days. Individual differences were observed in the duration and types of contact with objects. These observations contradict earlier reports that prosimians show little interest in inanimate, non-food objects.
In traditional classrooms, students are plagued with questions and concerns regarding assessment: "What are the instructions for section two again?" "How do we know what answer you're looking for on question five?" "I don't understand how I got this grade." In on-line classes, the same dilemmas appear more problematic. For example, Monaghan (1996) reports that some practitioners fear technology will never compensate for the understated elements of human interpersonal interaction when professors communicate with students. Indeed, cyberlearning is couched in an apparent paradox of twenty-four-hour access to the professor over the Internet but the absence of customary face-to-face interaction. This leaves room for open speculation whether it is more difficult in on-line classes than in face-toface classes to apprise students of assessment expectations. However, with the availability and efficiency of electronic communication, traditional and on-line courses can be very similar (Canada, 2000). For example, a fundamental component of both successful face-to-face and on-line classes is assessment, so it is not surprising that successful on-line programs pay careful attention to assessment. Carnevale (2001), for instance, describes how some of the nation's virtual universities use highly advanced outcomesbased assessment policies, including administering a battery of pre-and posttests to measure students' proficiency.Because of the concern about and development of assessment policies and measures for on-line classes, some predict that on-line evaluation will become the prototype for rating student performance in traditional institutions. Not every distance education program employs assessment models,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
