THE SAD REALITY OF CORRUPTION WE HAVE TO FACE.

Hi everyone, you owe it to yourself, your family, your country and the world to watch this and please
take it seriously. This is he reality of our corrupt world.

Boredom can lead to madness in parrots. The birds need constant interaction, affection, and mental stimulation; bird authorities have determined that some parrots have the mental abilities of a 5-year-old human child. When caged by themselves and neglected for long periods of time, these intelligent, sociable birds can easily become mentally ill. Many inflict wounds upon themselves, develop strange tics, and rip out their own feathers. Should a neglected parrot go mad, there is little that can be done to restore it to normalcy. In England, there are mental institutions for such unfortunate creatures.

If only our eyes could speak!

 

The following research further shows that we can listen to the human eyes not the human words reporting behaviors, images or events. The eyes encode images through eye movement, tracking, time and focus. Exposed to the same visuals, recognition & memory retrieval matching -eye tracking/movement/focus/time- can be verified.
"The witness points out the criminal in a police lineup. She swears she'd remember that face forever. Then DNA evidence shows she's got the wrong guy. It happens so frequently that many courts are looking with extreme skepticism at eyewitness testimony."

Where Is the Accurate Memory? The Eyes Have It

Is there a way to get a more accurate reading of memory? A new study says yes. "Eye movements are drawn quickly to remembered objects," says Deborah Hannula, assistant professor at the University of Wisconsin Milwaukee, who conducted the study with Carol L. Baym and Neal J. Cohen of the University of Illinois, Urbana-Champaign and David E. Warren of the University of Iowa College of Medicine. Tracking where and for how long a person focuses his or her eyes "can distinguish previously seen from novel materials even when behavioral reports fail to do so." The findings will appear in an upcoming issue of Psychological Science, a journal published by the Association for Psychological Science.
The researchers gave university students 36 faces to study. These target faces were also morphed to produce images closely resembling them; the morphed phases were not seen during the study phase. The students were then shown 36 three-face displays, one at a time. Told that the studied faces wouldn't always be there, the participants had to press a button indicating which face was the studied one, or simply choose a face if they felt none had been studied. They then reported verbally whether the studied target face was present or not. While they looked at the 3-face display, their eye movements were recorded, tracking where the eyes focused first and what proportion of time was spent looking there. For the analysis, the psychologists divided the faces into three groups: studied targets; morphs mistaken for the "target" face; and morphs chosen and known to be incorrect.
Participants easily identified the target faces most of the time. They also spent more time looking at these faces, and did so soon after the 3-face display had been presented. "The really interesting finding is that before they chose a face and pressed a button, there was disproportionate viewing of the target faces as compared to either type of selected face," said Hannula. However, "after the response was made, viewing tended to mimic the behavioral endorsement of a face as studied or not, whether that endorsement was correct or incorrect." In other words, "pre-response viewing seems to reflect actual experience, and post-response viewing seems to reflect the decision making process and whether or not the face will be endorsed as studied."
Hannula theorizes as to what is happening: "Early disproportionate viewing of the target face may precede and help give rise to awareness that a particular face has been studied. Subsequently, we begin to think about the choice that we're making" -- we look closely, compare and weigh the options -- "these cognitive processes permit us to make a decision, but may also lead us down the wrong path. In this case, leading us to endorse a face as studied despite having never seen it before."
Aside from the potential for practical application, says Hannula, eye movement methods could be used to examine memory in individuals -- like some psychiatric patients and children -- who may have trouble communicating what it is that they remember. "Eye movements might provide us with more information about what exactly these individuals remember than behavioral reports alone."
