Research found that anger can increase participants' analytical thinking, yet is often driven by mental shortcuts. The study suggests that angry individuals can process information analytically, but are influenced by cognitive biases.
Researchers discovered that nonconscious exposure to a significant person's name can cause individuals to act in defiance of their partner's or boss's wishes. People with high levels of reactance tend to be more resistant to these influences.
Researchers found that touch tracking bypasses the brain's cognitive system, allowing participants to perform multiple tasks simultaneously. This breakthrough could help individuals with coordination problems improve their hand movements.
Researchers conducted experiments on 200 people, finding that snap judgments about faces are formed rapidly, often before rational thought can influence the reaction. The study suggests that our intuitions about attraction and trust are among the fastest and most intuitive judgments we make.
Researchers found that people tend to consume a single unit of food when served in a small portion, despite the actual quantity being larger. This 'unit bias' helps explain how environmental factors influence eating habits and may contribute to obesity.
A new study finds that same-sex segregation can be beneficial for some students, particularly those who are resilient to stereotypes and able to moderate their behavior. However, it can also create disadvantages for others who struggle with these skills.
A study by Association for Psychological Science found that pairs can coordinate through haptic interactions, leading to improved performance and development of cooperative strategies. The researchers speculate that this capacity is a fundamental human ability used in various daily activities.
Research found that people from stigmatized groups experience increased anxiety and stress, depleting their self-control when faced with threats or prejudice. This interference affects academic performance, including note-taking, study habits, and test scores.
A team of Cornell University researchers used golden hamsters to study individual recognition, finding that different brain areas react differently depending on emotions attached to memories. The study's findings may have implications for understanding and treating social anxiety disorders, Asperger syndrome, and autism.
Researchers Kerry Jordan and Elizabeth Brannon found that seven-month-old infants spent more time looking at video images matching the number of women talking, similar to monkeys who chose videos with matching sounds. The study suggests an internal representation of 'two-ness' or 'three-ness' in preverbal infants.
A nine-year study found that alcohol deterrents can help patients achieve long-term abstinence, with an abstinence rate of over 50 percent. The study suggests that the psychological role of ADs plays a key role in relapse prevention and maintenance of abstinence.
Psychologists at the University of Liverpool found that people believe they can see themselves even before they are level with the near edge of a mirror. Participants failed to recognize that the image on the surface of a mirror is half the size of the observer due to its midpoint between them and the reflected image.
Rutgers-Newark psychology researchers found that individuals with selective and complete haptic deafferentiation, a rare neurological disorder, struggle to simulate others' actions due to lack of body perception. They successfully estimated weight but failed to recognize deception.
A recent study found that motion significantly enhances people's ability to recognize subtle facial expressions, particularly when displayed dynamically rather than statically. The research suggests that motion reveals the temporal characteristics of emotions and improves sensitivity to communication of emotion.
A study led by Penn State University assistant professor Theresa Vescio found that patronizing behavior, characterized by giving subordinates praise while withholding resources, can lead to negative performance outcomes for women. This subtle form of sexism may allow discriminatory practices to go unnoticed.
A large-scale study identified a genetic basis for certain behaviors, including alcohol consumption, suggesting that genetic make-up may influence drinking habits. The research focused on the dopamine D2 receptor gene (DRD2) and found a strong association between this gene variant and alcohol consumption.
Researchers at Ohio State University conducted experiments showing that white Americans are more likely to misidentify tools as guns when shown a picture of an African American before seeing the tool or gun. In contrast, they were less likely to make this mistake when shown a picture of a white person. The study suggests that unconscio...
Researchers found that individuals in a positive mood tend to have unreliable memories and poor critical thinking skills, while those in a negative mood provide more accurate eyewitness accounts. In contrast, a negative mood state triggers more systematic information processing, leading to superior thinking and communication skills.
A recent study by Dr. Douglas Wahlsten found that environmental influences significantly impact experiment outcomes in mice, including motor coordination and psychological learning tasks. The study suggests that even small factors like odors and experimenter conduct can have a profound effect on behavior.
At 2-6 months old, infants learn to connect visible bits and pieces of the world to form mental representations. By 4 months, they can accurately perceive occlusions in object trajectories, laying the foundation for lifelong visual perception.
Research by Dugatkin and colleagues shows that observing fights in swordtail fish affects their likelihood of winning. Psychological factors play a significant role in animal societies, predicting the outcome of interactions between group members. These findings have implications for understanding human social dynamics.
A study by European psychologists found that people remember natural scenes significantly better when they're in color rather than black and white. The researchers also discovered that unnatural colors do not strengthen memory, suggesting that the brain is tuned to the color structure of the world.
Researchers found that different brain pathways handle mental rotation and object recognition tasks, indicating distinct neural circuits. The ventral pathway is involved in object identity, while the dorsal pathway is linked to spatial location.
A new study shows that 14-month-olds can imitate a novel means action modelled to them, but only if it's considered the most rational alternative. This indicates that imitation of goal-directed action is a selective interpretative process. In contrast, infants perform the 'hand-action' automatically, suggesting an emulation-like process.
Golf putting study reveals that over-attending to well-learned skills can hinder performance, especially under pressure. The experiment shows that adapting to an environment where individuals focus on performance from the start of learning may provide immunity against 'choking'.
Researchers found that repeatedly exposing people to positive images of stigmatized groups, such as African Americans and the elderly, can alter their nonconscious attitudes towards those groups. This strategy may help reduce prejudices and improve social welfare.
Three new studies show that expressing positive emotions can lead to better relationships, mental focus, and personal well-being. Additionally, research finds that a positive outlook on life persists into old age, with extraverted individuals less likely to experience a decline in positive affect.
A new study by Kent State University psychologist Daniel T. Levin found that people's brains tend to classify faces as belonging to a specific race, rather than recognizing individual features. This 'cross-race recognition deficit' affects people of all racial groups and can lead to inaccurate identifications.
A study at Ohio State University linked job stress to back pain in introverted individuals and those who dislike repetitive tasks. The researchers tested how students reacted to critical supervision while lifting boxes, finding that stressed individuals used their muscles differently, leading to increased spinal forces.
A new study found that individuals with a sensation-seeking personality are more sensitive to nicotine's mood-altering effects, particularly at lower doses. This increased sensitivity may be a key factor in their risk of becoming smokers.
Researchers found that amygdala activity levels are related to unconscious social evaluation, but not conscious attitudes. The study used fMRI to examine the role of the amygdala in racial evaluation and found a significant link between neural activity and implicit race bias.
Researchers found that attempting to control reactions to emotional events weakens memory, but reappraisal strategies have no such impact. The study suggests that expressive suppression, which involves continually monitoring and correcting oneself, consumes cognitive resources and reduces accuracy of event details.
Researchers developed a new virtual reality exposure therapy called Virtual Reality Exposure (VRE) to help individuals with a fear of flying. After eight sessions, participants showed significant reductions in anxiety and fear, with 93% having flown six months after treatment.
A new study found that non-medicated ADHD children are three times slower than their non-ADHD counterparts when making quick decisions. However, when treated with Ritalin, the ADHD children's reaction times returned to normal.
A new study by the American Psychological Association found that a firm handshake is associated with a favorable first impression for both males and females. The study suggests that consistent handshaking is related to personality traits such as extraversion and openness.
A study found that people with a particular variation in the serotonin transporter gene (5-HTT) showed a greater fear response during a laboratory experiment. This variation is linked to increasing regulation of serotonin levels in the brain, which may play a role in anxiety disorders.
Researchers have developed a model called Reconstruction After Feedback with Take the Best (RAFT) that explains how hindsight bias occurs. Consistent with the model, experiments found that knowledge of nutrition values was updated with feedback, reducing hindsight bias.

The study also found that brain cells producing citrulline significantly correlated with female mouse aggressiveness.
Research suggests Tourette's syndrome is not a simple motor disorder, but rather a condition affecting the brain's circuits that control planning and decision making. The study found that individuals with Tourette's can anticipate and adjust to their tics, indicating intentional movement.
A new study reveals that up to 44% of adults believe in the concept of 'immanent justice,' where bad behavior leads to severe illnesses. The study, conducted by Ohio State University researchers, found that language plays a significant role in shaping beliefs on this topic.
A study conducted at nine U.S. Centers found that a testosterone skin patch improves sexual function and psychological well-being in surgically menopausal women. The patch was well-tolerated and showed significant benefits in improving the quality of life for these women.
Research reveals that showing pictures of admired individuals from marginalized groups can significantly decrease unconscious prejudice. Exposure to images of admired blacks reduced levels of unconscious prejudice by one-third, while exposure to images of admired elderly people lowered ageism by a similar amount.
Research found that men and women have distinct reactions to stressors, including disagreements and skill challenges. Husbands tend to respond more strongly to perceived threats to their status and power, while wives are more reactive to interpersonal conflicts and quality of interaction.

Researchers found that young rats learned to distinguish lactating females from others through repeated trials, but did not yet recognize their mother. This study sheds light on the complex process of mammalian recognition and attachment.
Research reveals that positive feedback from law enforcement can distort eyewitness memories, making them more confident and accurate. The study suggests that this distortion can lead to innocent convictions, highlighting the need for supervised lineups and confidence assessments.
A new study finds that when remembering words, the brain activates the left side, while unfamiliar faces are processed by the right. However, both sides become active for objects with names.
Researchers at the University of Washington have developed a new test to assess rapid decision-making skills under heavy information load. The test, called the Abstract Decision Making task, was found to be predictive of performance in jobs such as emergency dispatching and air traffic control.
Researchers at Carnegie Mellon University found that direct instruction using the Control of Variables Strategy is effective in teaching young children about science. Children can distinguish between knowing an answer and having to guess with minimal training, making it a crucial process skill for scientific experimentation.
Selective hypothesis testing, considering only one possible outcome, contributes to overestimation of probability and increased gambling decisions. Training in abstract reasoning skills may counteract this influence.
Despite financial gains by some African Americans, racism may be getting worse in the US due to individual and institutional barriers. Expert James M. Jones recommends six steps to reduce prejudice, including joint cooperation, intergroup contact, and a greater appreciation of individual differences.
Cornell University psychologist Romi Nijhawan's experiment shows that the brain can decompose yellow into its constituent red and green based on motion of the stimulus. Human retinas cannot sense motion on their own, but the brain uses a process called motion extrapolation to correct for this delay.
According to psychologist Saul M. Kassin, modern interrogation techniques can elicit false confessions, compromising the justice system. Laboratory experiments demonstrate that innocent people can adopt false beliefs and confabulate details under suggestion.
