2010
We present a Turing-like Handshake test administered through a telerobotic system in which the interrogator is holding a robotic stylus and interacting with another party (human or artificial). We use a forced choice method, and extract a measure for the similarity of the artificial model to a human handshake.

The term "intelligence" is complex because it refers to both behavior and individuals, and its interpretation varies across cultures. European Americans tend to link intelligence with reasoning and cognitive skills, while in Kenya, it is tied to responsible participation in family and social life. In Uganda, intelligence is seen as the ability to know the right actions and carry them out effectively, while the Iatmul people of Papua New Guinea associate it with the capacity to remember detailed...

There is a need to develop alternative prosthesis attachment due to limb loss attributed to vascular occlusive diseases and trauma. The goal of the work is to introduce an osseointegrated intelligent implant design system to increase skeletal fixation and reduce periprosthetic infection rates for patients needing osseointegrated technology.

Measures of Intelligence

Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization. Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...

Working memory, attentional control, and relational reasoning contribute different functions. Working memory keeps task-relevant information available, while attentional control helps maintain focus as demands change. Relational reasoning then supports detection of connections among the available elements. Their coordination allows a person to compare patterns, retain intermediate information, and adjust a strategy without depending primarily on familiar facts.
Minimizing vocabulary and factual knowledge reduces the extent to which scores reflect what a person has already learned. This design directs the assessment toward handling novel task demands, detecting relationships, and applying reasoning strategies. It helps researchers distinguish flexible problem solving from performance supported mainly by acquired language or information.
Fluid intelligence is examined through performance on new problems, whereas knowledge-dependent reasoning draws more heavily on acquired vocabulary, facts, or practiced information. The contrast matters because people may differ in prior learning opportunities without showing the same pattern on tasks designed to emphasize adaptation and pattern discovery. Researchers can therefore study flexible reasoning as a distinct aspect of cognition.
Common measures include matrix reasoning and series completion tasks, along with other assessments designed to reduce dependence on acquired vocabulary or factual knowledge. These formats present structured problems in which participants must identify relevant patterns or rules and produce a solution. Researchers use them to examine flexible reasoning across related but not identical problem formats.
The assessment process centers on presenting problems that are unfamiliar enough to require active reasoning rather than simple recall. Depending on the instrument, a person may complete matrix reasoning, series completion, or another task requiring information to be held in mind while a rule is detected and an answer generated. Researchers use performance to investigate individual differences in flexible cognition.
Findings from Fluid intelligence research help psychologists examine how flexible reasoning changes across the lifespan and how it relates to cognitive development, aging, education, and individual differences. The measures also provide a way to compare performance when researchers want to limit the influence of vocabulary or factual knowledge. Their value lies in connecting task performance with broader theories of cognition.
