Octopuses have a fully boneless body and as well distributed intelligence, the ability to stretch, change the stiffness, and sense perception in all the body. This makes them the perfect source of inspiration for soft robotics technologies. [1] The abilities of octopuses have been imitated in robotics to develop artificial suckers [2][3][4] and soft robotic arms. [5][6][7][8] Chemotactile sensing and the adhesion of suckers are used in combination with arm movements to explore environments, manipulate objects, and capture prey, as well as for anchoring and locomotion. [9][10][11][12][13][14] An octopus can feel a slight touch in any part of its body since it is covered with mechanoreceptors, and the sense of touch is at its most sensitive in the suckers. [15] The sucker consists of two main regions connected by an orifice: the infundibulum, an exposed disk-like portion of the sucker, and the acetabulum, a spheroidal cavity with a protuberance at the base (Figure 1B). These regions have radial and meridional muscles (used for attachment) and circular muscles (used for active detachment). [14] Octopuses distinguish the shape and texture of objects using suckers with mechanoreceptors (Figure 1A). [16,17] Imitating these abilities in soft arms can lead to the development of a new generation of manipulators for blind exploration and manipulation in environments where there are no visual clues.Bioinspiration from octopus' suckers can provide artificial solutions for manipulating, grasping, and transferring objects of different dimensions, weight, and textures with no damage in both agriculture and industrial applications.Artificial suction cups can be classified based on their actuation method. [17] Passive suction cups mimic the natural structure of an octopus and exploit external preloads to adhere and attach to objects. They are effective at different scales, in both wet and dry environments. [2,4] On the other hand, active suction cups exploit soft actuators to create an inner negative pressure (Figure 1C). Fluidic actuation is the most used in suction cups [7,8,[18][19][20] but there are also solutions that exploit shape memory alloys, [21,22] electrohydrodynamic pumps, [23] or dielectric electroactive polymers. [24,25] Going beyond open-loop control entails integrating sensors into a soft body to provide sensory feedback. Ideally, to develop sensory suction cups (and soft robots), sensors should be: compliant to avoid negatively impacting on the mechanical properties of the body; sufficiently small to not hinder movement; resilient and robust to resist to mechanical stimulation; and repeatable. [26,27] The sensing technologies used to replicate human touch capabilities range from resistive, capacitive, optical to magnetic and

Studies are reviewed in which some well-known clinical tests of intelligence are abbreviated to save testing time. Serious methodological problems are evident in most of these studies: samples are often small, unrepresentative, and heterogeneous in composition; and short-form validity is systematically overestimated. It is argued that present statements of the problem do not lead to a unique solution. The general requirement that an abbreviated test should save time while retaining maximum validity cannot be satisfied in the absence of a statement about the relative utility of "time saved" and "validity lost." Future research should benefit by adopting a decision-theoretic approach to the validation of short-form tests.
