Evaluating Brain Performance Enhancing Drugs, Kristina Toropova
Evaluating Brain Performance Enhancing Drugs, Kristina Toropova
Open Educational Resources
Students read about drugs which enhance student academic performance.They will connect the found information to prior course material, addressing neuroanatomy and neurophysiology as well as connect to the attention course chapter. Students will also delve into the ethical components of the use of brain enchasing drugs and compare them to sports performance-enhancing drugs.
Visual Saliency Influences Ethical Blind Spots And (Dis)Honesty, Andrea Pittarello, Marcella FrăTescu, Sebastiaan MathôT
Visual Saliency Influences Ethical Blind Spots And (Dis)Honesty, Andrea Pittarello, Marcella FrăTescu, Sebastiaan MathôT

Recent work suggests that dishonesty results from ethical blind spots: people’s lack of attention to ethical information. In two experiments (one pre-registered) we used eye tracking to investigate when ethical blind spots emerge, and whether they can be reduced through a simple, non-invasive intervention. Participants reported a Target Digit indicated by a jittery cue that was slightly biased in the direction of another digit (the Second-Cued Digit), which could be either higher or lower than the Target Digit. Participants were paid more for reporting higher digits, and were not penalized for making mistakes, thus providing an incentive to cheat. Results …
Language Experience With A Native-Language Phoneme Sequence Modulates The Effects Of Attention On Cortical Sensory Processing, Valerie L. Shafer, Monica Wagner, Jungmee Lee, Francesca Mingino, Colleen O'Brien, Adam Constantine, Mitchell Steinschneider

Auditory evoked potentials (AEP) reflect spectro-temporal feature changes within the spoken word and are sufficiently reliable to probe deficits in auditory processing. The current research assessed whether attentional modulation would alter the morphology of these AEPs and whether native-language experience with phoneme sequences would influence the effects of attention. Native-English and native-Polish adults listened to nonsense word pairs that contained the phoneme sequence onsets /st/, /sət/, /pət/ that occur in both the Polish and English languages and the phoneme sequence onset /pt/ that occurs in the Polish language, but not the English language. Participants listened to word pairs within two …
Attention Strongly Modulates Reliability Of Neural Responses To Naturalistic Narrative Stimuli, Jason J. Ki, Simon P. Kelly, Lucas C. Parra
Attention Strongly Modulates Reliability Of Neural Responses To Naturalistic Narrative Stimuli, Jason J. Ki, Simon P. Kelly, Lucas C. Parra

Attentional engagement is a major determinant of how effectively we gather information through our senses. Alongside the sheer growth in the amount and variety of information content that we are presented with through modern media, there is increased variability in the degree to which we “absorb” that information. Traditional research on attention has illuminated the basic principles of sensory selection to isolated features or locations, but it provides little insight into the neural underpinnings of our attentional engagement with modern naturalistic content. Here, we show inhumansubjects that the reliability of an individual’s neural responses with respect to a larger group …
Rumination And Rebound From Failure As A Function Of Gender And Time On Task, Ronald C. Whiteman, Jennifer A. Mangels
Rumination And Rebound From Failure As A Function Of Gender And Time On Task, Ronald C. Whiteman, Jennifer A. Mangels

Rumination is a trait response to blocked goals that can have positive or negative outcomes for goal resolution depending on where attention is focused. Whereas “moody brooding” on affective states may be maladaptive, especially for females, “reflective pondering” on concrete strategies for problem solving may be more adaptive. In the context of a challenging general knowledge test, we examined how Brooding and Reflection rumination styles predicted students’ subjective and event-related responses (ERPs) to negative feedback, as well as use of this feedback to rebound from failure on a later surprise retest. For females only, Brooding predicted unpleasant feelings after failure …
The Effects Of Changing Attention And Context In An Awake Offline Processing Period On Visual Long-Term Memory, Timothy M. Ellmore, Anna Feng, Kenneth Ng, Luthfunnahar Dewan, James C. Root
The Effects Of Changing Attention And Context In An Awake Offline Processing Period On Visual Long-Term Memory, Timothy M. Ellmore, Anna Feng, Kenneth Ng, Luthfunnahar Dewan, James C. Root

There is accumulating evidence that sleep as well as awake offline processing is important for the transformation of new experiences into long-term memory (LTM). Yet much remains to be understood about how various cognitive factors influence the efficiency of awake offline processing. In the present study we investigated how changes in attention and context in the immediate period after exposure to new visual information influences LTM consolidation. After presentation of multiple naturalistic scenes within a working memory paradigm, recognition was assessed 30 min and 24 h later in three groups of subjects. One group of subjects engaged in a focused …
Iconic Memory Requires Attention, Marjan Persuh, Boris Genzer, Robert D. Melara
Iconic Memory Requires Attention, Marjan Persuh, Boris Genzer, Robert D. Melara
Publications and Research
Two experiments investigated whether attention plays a role in iconic memory, employing either a change detection paradigm (Experiment 1) or a partial-report paradigm (Experiment 2). In each experiment, attention was taxed during initial display presentation, focusing the manipulation on consolidation of information into iconic memory, prior to transfer into working memory. Observers were able to maintain high levels of performance (accuracy of change detection or categorization) even when concurrently performing an easy visual search task (low load). However, when the concurrent search was made difficult (high load), observers' performance dropped to almost chance levels, while search accuracy held at single-task …
Attention And Olfactory Consciousness, Andreas Keller
Attention And Olfactory Consciousness, Andreas Keller
Publications and Research
Understanding the relation between attention and consciousness is an important part of our understanding of consciousness. Attention, unlike consciousness, can be systematically manipulated in psychophysical experiments and a law-like relation between attention and consciousness is waiting to be discovered. Most attempts to discover the nature of this relation are focused on a special type of attention: spatial visual attention. In this review I want to introduce another type of attention to the discussion: attention to the olfactory modality. I will first clarify the position of attention to smells in a general taxonomy of attention. I will then review the mechanisms …
