Psychology - Learning and Cognition: Attention Approach

Simons and Chabris (1999)

investigated inattentional blindness by asking participants to watch a video of two basketball teams passing balls and count the passes made by one team. During the video, a person in a gorilla suit walked through the scene for about 9 seconds. About 50% of participants did not notice the gorilla, showing that focused attention can cause people to miss obvious stimuli. This study supports the idea that attention is limited and can reduce awareness of unexpected events.

Strayer and Johnson (2001)

investigated how cell phone use affects divided attention while driving. Participants used a driving simulator while either driving normally or talking on a hands-free phone, and reaction times to traffic signals were measured. Drivers talking on the phone reacted more slowly and missed more signals. This shows that multitasking reduces attention and increases the risk of errors.

Wulff and Hyman (2022)

investigated inattentional deafness by asking participants to complete visual attention tasks while sounds played in the background. Many participants failed to notice the sounds when their attention was focused on the visual task. This suggests that attention limits affect auditory processing as well as visual processing. The study supports the idea that attention resources are limited across senses.

Rosenberg et al. (2016)

investigated the brain networks involved in sustained attention using fMRI scans while participants completed attention tasks. They found that patterns of connectivity between different brain regions predicted how well participants performed on attention tasks. This showed that attention depends on a network of brain areas rather than a single brain structure. The findings support the biological basis of attention and the network model of attention.

Chang et al. (2013)

investigated biological differences in individuals with ADHD using neuroimaging techniques to compare brain structure between children with ADHD and control groups. They found differences in brain regions linked to attention and impulse control. This suggests that ADHD is associated with biological brain differences. The study supports biological explanations of attention and ADHD.

Braat-Eggen et al. (2020)

investigated the effect of background noise on attention by having office workers complete tasks in quiet and noisy environments. Performance decreased and more errors occurred in noisy conditions. This suggests that environmental noise increases cognitive load and reduces attention efficiency. The study supports the role of environmental factors in attention.

Stevenson et al. (2018)

investigated whether exposure to nature improves attention by showing participants natural or urban environments before completing attention tasks. Participants who were exposed to natural scenes performed better on the tasks. This supports attention restoration theory, which suggests that natural environments help restore attention. The findings highlight the positive role of environment on cognitive performance.

Ward et al. (2017)

investigated the effect of smartphone presence on attention by asking participants to complete memory tasks with their phone visible, nearby, or in another room. Performance was worst when phones were visible and best when phones were removed from the room. This suggests that smartphones reduce attention even when not being used because they increase cognitive load. The study highlights the negative impact of technology on attention.

Baughan and Olivera (2021)

investigated cultural differences in attention by comparing how participants from different cultures processed visual information. They found differences in how much attention was given to context versus main objects. This suggests that culture influences how people direct attention. The study supports cross-cultural differences in cognition.

Cenek et al. (2025)

investigated cultural differences in visual attention using eye-tracking technology to measure where participants focused their gaze. They found that participants from different cultural backgrounds showed different visual scanning patterns. This suggests that culture shapes how attention is allocated visually. The findings support the idea of holistic versus analytic attention.

Henrich et al. (2010)

reviewed psychological studies to examine the use of WEIRD (Western, Educated, Industrialized, Rich, Democratic) populations. They found that most research participants came from WEIRD societies, even though these populations represent a small percentage of the world. This suggests that many findings may not generalize globally. The study highlights cultural bias and issues with external validity.

Masuda and Nisbett (2001)

investigated cultural differences in attention by showing American and Japanese participants animated underwater scenes. Participants described what they noticed, and Americans focused more on central objects while Japanese participants focused more on background details and relationships. This suggests that Western cultures use analytic attention while East Asian cultures use holistic attention. The findings show that culture influences how attention is directed.

Masuda and Nisbett (2003)

investigated how culture influences memory for objects in context by showing participants objects placed on backgrounds and later testing recall. Japanese participants remembered background context better than American participants. This suggests that culture affects attention to context. The study supports cultural influences on both attention and memory.

Broadbent (1958)

proposed the filter model of attention based on findings from dichotic listening experiments, where participants listened to different messages in each ear. Participants were able to recall attended messages but not unattended ones. Broadbent concluded that attention acts as an early filter that blocks irrelevant information before meaning is processed. This model explains selective attention but cannot explain phenomena like the cocktail party effect.

Schneider and Shiffrin (1977)

investigated automatic and controlled processing using visual search tasks repeated many times. They found that with practice, tasks became automatic and required less conscious attention. This suggests that repeated experience allows tasks to become automatic. Their findings support the automaticity model of attention.

Stroop (1935)

investigated interference in attention using a task where participants named the ink color of words that either matched or conflicted with the color name. Participants were slower when the word meaning conflicted with the ink color (e.g., "RED" printed in blue ink). This showed that automatic processes interfere with controlled attention. The study demonstrates how executive control is required to override automatic responses.
