Four studies examined dyadic collaboration on quantitative estimation tasks. In accord with the tenets of “naïve realism,” dyad members failed to give due weight to a partner’s estimates, especially those greatly divergent from their own. The requirement to reach joint estimates through discussion increased accuracy more than reaching agreement through a mere exchange of numerical “bids.” However, even the latter procedure increased accuracy, relative to that of individual estimates (Study 1). Accuracy feedback neither increased weight given to partner’s subsequent estimates nor produced improved accuracy (Study 2). Long-term dance partners, who shared a positive estimation bias, failed to improve accuracy when estimating their performance scores (Study 3). Having dyad members ask questions about the bases of partner’s estimates produced greater yielding and accuracy increases than having them explain their own estimates (Study 4). The latter two studies provided additional direct and indirect evidence for the role of naïve realism.

This research deals with the interplay of mood and multiple source characteristics in regard to persuasion processes and attitudes. In a four-factorial experiment, mood (positive vs. negative), source consensus status (majority vs. minority), source trustworthiness (high vs. low), and message strength (strong vs. weak) were manipulated. Results were in line with predictions of a mood-congruent expectancies perspective rather than competing predictions of a mood-as-information perspective. Specifically, individuals in both moods evinced higher message scrutiny given mood-incongruent (vs. mood-congruent) source characteristics.That is, across source trustworthiness, positive (negative) mood led to higher message scrutiny given a minority (majority) versus a majority (minority) source. Furthermore, across source consensus, positive (negative) mood led to higher message scrutiny given an untrustworthy (trustworthy) versus a trustworthy (untrustworthy) source. Additional analyses revealed that processing effort increased from doubly mood-congruent source combinations (low effort) over mixed-source combinations (intermediate effort) to doubly mood-incongruent combinations (high effort). Implications are discussed.

A recently published paper highlights that while the risk of post-traumatic stress disorder (PTSD) is more common in those with migraine than those without migraine irrespective of sex, the risk is greater in male migraineurs than female migraineurs…

When we’ve got a problem to solve, we don’t just use our brains but the rest of our bodies, too. The connection, as neurologists know, is not uni-directional. Now there’s evidence from cognitive psychology of the same fact. “Being able to use your body in problem solving alters the way you solve the problems,” says University of Wisconsin psychology professor Martha Alibali…

A team of Scripps Research Institute scientists has found a key biological mechanism underpinning the transition to alcohol dependence. This finding opens the door to the development of drugs to manage excessive alcohol consumption…

How do people who speak more than one language keep from mixing them up? How do they find the right word in the right language when being fluent in just one language means knowing about 30,000 words? That’s what science has wondered about for decades, offering complicated theories on how the brain processes more than one language and sometimes theorizing that bilingualism d…

Johns Hopkins Children’s Center scientists have found that having a regular outpatient mental health provider may not be enough to prevent children and teens with behavioral problems from repeatedly ending up in the emergency room. The study is published in the June 1 issue of the journal Psychiatric Services…

Increased knowledge about mental illness, attitudes of tolerance toward people with mental illness, and support for providing them with care in the community lead to an increased likelihood of individuals seeking help, according to research appearing in the June issue of the American Psychiatric Association’s journal Psychiatric Services…
