Attention

• What about attention span? It depends…

Focused Attention (short bursts) - requires the least amount

Sustained Attention (long periods)

Selective Attention (filtering)

Alternating Attention (task switching)

Divided Attention (multitasking) - requires the most amount o

Selective Attention: filtering

• Our minds deceive us

Monkey business illusion

• Filtering irrelevant information--not distracted

Test your motion detection

• Ability to inhibit irrelevant material relates to higher order

cognitive functions; there is a link between sensorydiscriminations and IQ.

Test your attention span

Research: sustained attention

• Researchers used closed-loop neurofeedback to improve sustaattention.

The focus of attention was monitored in real time.• Feedback was given when indicators of an attentional lapse we

detected in the brain.

• Behavioral performance improved after one training session.

• Students task switch often while studying and during class

• 91% college students sent or received a text (Tindell &Bohlander, 2012)

• 75% college students checked text messages everyhour or less (Rosen et al., 2012)

• 41% felt anxious if they could not check texts or social

media (Rosen et al., 2011)

• Reading habits: Does scrolling encourage skimming vs. diving?

• Effort: How does access to instant, digital information impactintellectual efforts?

• Handwriting: Are devices displacing handwriting?

Your brain on books

Books provide physical cues that effect brain processesand learning:

• Books give a mental orientation

(beginning, middle, end)

• Books provide intuitive navigation and mental maps

• Books make it easier to comprehend chronological order

• Books offer contextual cues

(i.e., studying on monitor relies on memory recall vs. knowing)

• There is a scarcity of research on the effects of digital readinrelation to recall accuracy and comprehension.

• This study draws upon concepts, principles, and assumptionassociated with cognitive information-processing.

• The results point educators to possible areas of concern reginstructional and educational decisions: 1) whether to use edevices for specific activities or assignments and 2) determiuse of test scores originating from electronic devices.

To determine the effects of reading mode, the researcher tested hypotheses:

• H1: Students who read a paper article will have a statistically sigdifference in greater recall accuracy as shown by test scores comthose who read the same digital article using a tablet.

• H2: Students who read a paper article will have a statistically sigdifference in reading comprehension as shown by higher test sccompared to those who read the same digital article using a tab

• Digital screen readers engaged in greater use of shortcuts (i.e., browkeywords).

• Two similar patterns emerged in separate studies by Niccoland Johnson (2013):

1) there was no significant difference in group test score mebetween digital tablet and paper readers and

2) paper readers showed higher frequency rates of the two scores.

Both studies show no differences in group means, even thousamples were demographically different.

• Concerns remain about the influence of digital reading for in-dcomprehension (Rosenwald, 2014).

• If educators understand the effects of digital reading on the deof deep reading, and students’ grasp of difficult material, they formulate instructional decisions.

•Questions linger regarding the consequences on brain processnonlinear reading, especially adaptive shortcuts due to scrollinhyperlinks (Wolf & Barzillai, 2009).

• Consider longer readings that create a slight increase in cognitfor digital readers.

• Include a longer time interval between reading and assessing.

• Extend to primary and secondary students to explore developpatterns.

• Consider other factors, such as types of reading and academicdiscipline.

• Half of the students kept their cell phones on the desk duringthe experiments and the other half kept the phones away.

• Just the presence of a phone was found to severely limitreaction times.

• Tech breaks: 10-15 min. in school.

(Out of sight ≠ out of mind: it hurts thinking aboutdevices!)

• Teach and practice close and deep reading; developbi-literacy.

• Apply self-regulation and metacognition skills forboth print and digital reading.

• Teach and practice mindfulness.
