Econometric Views (EViews)01:29

Econometric Views (EViews)

587
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

Location and Orientation of the Heart01:13

Location and Orientation of the Heart

10.4K
The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Temperature Dependence on Reaction Rate

The Collision Theory
Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical bonds. This premise is the basis for a theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates.
The collision theory is based on the postulates that (i) the reaction rate is proportional to the rate of reactant collisions, (ii) the reacting species collide in an orientation allowing contact between...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

4.5K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

System of Memory01:23

System of Memory

7.4K
Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their capacity and the duration for which they can hold information. Sensory memory captures raw sensory input from the environment, holding it for just a few seconds or less. For example, on hearing a brief, loud sound, like a car horn honking, the sound seems to linger in the mind for a moment even after it stops. This is an instance of sensory memory...

Working Memory01:24

Working Memory

902
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Summary

Spatial memory from mobile devices is orientation-dependent. Physical movement during learning enhances spatial information encoding compared to simulated movement on screen.

Area of Science:

  • Cognitive Psychology
  • Human-Computer Interaction
  • Spatial Cognition

Background:

  • Mobile devices are increasingly used to view spatial information.
  • Understanding how users encode and retrieve spatial data from screens is crucial for interface design.
  • Previous research has not fully explored the impact of orientation and movement type on spatial memory formation via mobile devices.

Purpose of the Study:

  • To investigate if spatial representations of scenes viewed on mobile devices are orientation-dependent.
  • To determine if physical movement versus simulated movement during learning affects spatial information encoding and retrieval.
  • To assess the influence of movement type on the accuracy and speed of spatial memory recall.

Main Methods:

  • Participants studied a spatial layout on a tablet.
  • Two conditions were used: physical rotation of the tablet with the body, and simulated viewpoint changes via screen swiping.
  • Perspective-taking trials were conducted where participants localized objects from imagined viewpoints.

Main Results:

  • Participants demonstrated faster and more accurate object localization when the imagined perspective aligned with their initial physical orientation during learning.
  • No significant differences in retrieval accuracy or speed were observed between physical and simulated movement conditions during the pointing task.
  • Encoding of spatial information was faster with physical movement compared to simulated movement.

Conclusions:

  • Spatial representations formed from mobile device screens are indeed orientation-dependent.
  • Physical engagement with the learning material, involving body movement, facilitates faster encoding of spatial information.
  • Interface designers should consider the role of orientation and physical interaction in optimizing spatial learning on mobile devices.
