A bank teller was so distracted by the sight of a bank robber's weapon that she failed to perceive important features of the criminal's physical appearance. This best illustrates the impact of:

The bank teller shows the impact of shock and terror.

Explanation:

The bank teller themselves in the extraordinary circumstance of a bank robbery and was faced with a gun to their face and thus only remembers what is out of the ordinary.

The gun was a source of horror and trauma for the bank teller so it is that that they remember in vivid detail as their mind would have been completely focused on the gun and not much else.

Due to this unrelenting focus on the gun she would not have noticed the face of the person wielding that gun.

A bank teller was so distracted by the sight of a bank robber's weapon that she failed to perceive important features of the criminal's physical appearance. This best illustrates the impact of: selective attention.

Explanation:

Selective attention means concentrating or focusing on a particular object in the environment for specific period of time. It helps us to increase our concentration and ignore the unimportant details.

Selective attention helps in effective functioning of the human brain. The four main types of attention are as follows:

i)Selective attention

ii)Divided attention

iii)Sustained attention

iv)Executive attention

In the above scenario, bank teller was concentrating on the bank robber’s weapon. So she couldn’t recognize the physical appearance of the criminal.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
