Agnosia and Attention  

Interference with cognition based on visual perception seems to be very important in the  “Internet Age,” when information is transmitted through increasingly visual methods. The  various types of agnosia would seem to present significant interference with many kinds of  information on the Internet. Videoconferencing, for instance, is growing in popularity. I  FaceTime with my family in California on almost a daily basis, and my husband has had several  Skype job interviews. If an individual suffered from prosopagnosia, a disorder in which an  individual can see the features of a face, but not recognize who the face belongs to (Werner,  2010), such experiences would be next to impossible to manage. Infographics, a method of  presenting nuggets of data in a visual manner, would also lead to problems for agnosics. These  graphic representations of data often use layers of shapes, colors, numbers, and words to present  data that would present difficulties to those who suffer from apperceptive or object-specific  agnosia. In addition, the dependence on visual information complicates the discussion of  attention and cell-phone use. Navigation systems, whether on a smart phone or on the  dashboard, present perceptive distractions to a driver just like talking or texting on a cell phone.  Strayer and Johnston (2001) hypothesize that distraction while using cell phones is attentional  because the driver must pay attention to the conversation rather than driving. Navigation  systems would seem to create similar distractions, as the driver pays attention to either looking at  a map or listening to the voice giving directions. It seems important to conduct research on the  increasing presence of visual information in our lives to determine how individuals, whether they  suffer from agnosia or not, are affected by having to process this information, as well as to determine if the innovative use of technology to generate new kinds of visual information  uncovers new kinds of agnosia.  

The Memory Pill  

Propranolol, the “memory pill,” would seem to have many applications that present  opportunities for research. The memory pill is currently being used to help treat post-traumatic  stress disorder (PTSD) in soldiers and rape victims, although the drug’s use is still in the early  stages of testing (Finkelstein, 2007). If the trials continue to go well, there seem to be a number  of situations that would benefit from the use of propranalol, such as abused children, who can  also develop PTSD as a result of abuse. Studies would first have to determine whether  propranalol would help these children, and further if children might suffer from a unique set of  side effects, similar to the situation of Prozac that has particular side effects on teens. In  addition, research could examine how propranalol helps those with PTSD to see if other  medications could be used to treat other disorders. Propranalol, although it is called the  “memory pill,” does not change a person’s memory; rather, it suppresses the release of  adrenaline in reaction to the memory of a traumatic event (Finkelstein, 2007). Research could  investigate if the suppression of chemical response would be an effective treatment for other  disorders as well.  

Intelligence Tests and Education  

There seem to be some problems with standard intelligence tests. First, it is unclear  exactly what “intelligence” means: there are competing theories ranging from Spearman’s two factor theory to Gardner’s theory of multiple intelligences (Smilek, Sinnett, & Kingstone, 2013). 

Second, there can be biases and issues that affect an individual’s test scores that are not part of  the test, such as the Flynn effect (Smilek, Sinnett, & Kingstone, 2013). Nonetheless, intelligence  tests are viewed as reliable because they can accurately predict an individual’s academic grades  (Smilek, Sinnett, & Kingstone, 2013). If this issue is examined from the opposite perspective,  questions regarding grading and assessment in school could be raised. First, it would seem that  grades, at least in part, measure intelligence. Intelligence is seen as a practical trait (Smilek,  Sinnett, & Kingstone, 2013), and academics is one place that intelligence is practiced. If  traditional understandings of intelligence are unable to reach a consensus, it would seem  reasonable to suggest that traditional grades do not effectively measure the practice of  intelligence. Second, if the multiple intelligences theory is sound, then it could be asked if all  intelligences are graded in school. Students receive grades in math and English, but rarely, if  ever, do they receive grades for social, creative, and emotional intelligence. Academic grades,  then, would seem not to measure a student’s entire intelligence. Finally, movements such as the  Common Core, which attempt to standardize education at a national level, must be sure to take  into account external factors such as the Flynn effect when establishing performance levels. If  academic grades are a measure of a student’s intelligence, it seems imperative that educators take  the research into intelligence into account when determining how to assess and grade a student’s  application of intelligence.
