Sexual Orientation, Controversy, and Science
Psychological Science in the Public Interest (Volume 17, Number 2) Read the Full Text (PDF, HTML) Over the last 50 years, political rights for lesbian, gay, and bisexual (LGB) individuals have significantly broadened in some countries, while they have narrowed in others. In many parts of the world, political and popular support for LGB rights hinges on questions about the prevalence, causes, and consequences of non-heterosexual orientations. In this report (Volume 17, Number 2), J.

New Research From Psychological Science
Read about the latest research published in Psychological Science: Limits of Executive Control: Sequential Effects in Predictable Environments Frederick Verbruggen, Amy McAndrew, Gabrielle Weidemann, Tobias Stevens, and Ian P. L. McLaren Studies have shown that bottom-up processes modulate performance in unpredictable environments, but is this also true in predictable environments? Participants completed a go/no-go task in which the trials alternated predictably. Before seeing each stimulus, participants had to rate the extent to which they thought the go or no-go stimulus would appear.

Intuition – It’s More Than a Feeling
Great leaders make smart decisions, even in difficult circumstances. From Albert Einstein to Oprah Winfrey, many top leaders ascribe their success to having followed their intuition. New research shows how going with our gut instincts can help guide us to faster, more accurate decisions. Intuition — the idea that individuals can make successful decisions without deliberate analytical thought — has intrigued philosophers and scientists since at least the times of the ancient Greeks. But scientists have had trouble finding quantifiable evidence that intuition actually exists.

Neuroimaging Highlights Emotion Perception and Memory
Perception often is thought of in terms of sensory stimuli — what we see, hear, and smell — but it extends beyond the five senses, including complex function of emotional perception. We also can turn this perception inward, toward our own appraisal of an emotional stimulus. Thus, emotional perception can be split into two categories depending on the direction of attention: Focusing our attention outward to stimuli in our external environments is known as external perceptual orienting (EPO), while interoceptive self-orienting (ISO) is the opposite — directing our attention toward our own internal appraisal of a stimulus.

To Be More Persuasive, Repeat Yourself
The philosopher Plato wrote that there is no harm in repeating a good thing. Even better, a new study finds that repeating key points during your next meeting is a good way to sway colleagues’ decisions. Across two experiments, Stefan Schulz-Hardt (Georg-August-University) and colleagues demonstrated that repeating specific information during a discussion was enough to change someone’s mind. “From a rational point of view, information repetitions constitute redundancy and, hence, should not affect the recipient's decision,” the researchers write.
