Visual perception and emotion are traditionally considered separate domains of study. In this article, however, we review research showing them to be less separable than usually assumed. In fact, emotions routinely affect how and what we see. Fear, for example, can affect low‐level visual processes, sad moods can alter susceptibility to visual illusions, and goal‐directed …

The purposes of this project were to determine mental training-induced strength gains (without performing physical exercises) in the little finger abductor as well as in the elbow flexor muscles, which are frequently used during daily living, and to quantify cortical signals that mediate maximal voluntary contractions (MVCs) of the two muscle groups. Thirty young, healthy …
Witt, J. K., Proffitt, D. R., & Epstein, W. (2004). Perceiving distance: A role of effort and intent. Perception, 33(5), 577-590.
Perceiving egocentric distance is not only a function of the optical variables to which it relates, but also a function of people’s current physiological potential to perform intended actions. In a set of experiments, we showed that, as the effort associated with walking increases, perceived distance increases if the perceiver intends to walk the extent, …
Foster, K. R., &Kokko, H. (2008). The evolution of superstitious and superstition-like behaviour. Proceedings of the Royal Society B: Biological Sciences, 276(1654), 31-37.
Superstitious behaviours, which arise through the incorrect assignment of cause and effect, receive considerable attention in psychology and popular culture. Perhaps owing to their seeming irrationality, however, they receive little attention in evolutionary biology. Here we develop a simple model to define the condition under which natural selection will favour assigning causality between two events. …
Helmuth, L. (2003). Fear and trembling in the amygdala. Science, 300(5619), 586-569.
Summary Fittingly, one of the hottest topics at a recent meeting in New York during a terrorism alert was how fear makes its way through the human brain and guides attention–even without the aid of the conscious mind. Helmuth, L. (2003). Fear and trembling in the amygdala. Science, 300(5619), 586-569. DOI: 10.1126/science.300.5619.568
Losada, M., &Heaphy, E. (2004). The role of positivity and connectivity in the performance of business teams: A nonlinear dynamics model. American Behavioral Scientist, 47(6), 740-765.
Connectivity, the control parameter in a nonlinear dynamics model of team performance is mathematically linked to the ratio of positivity to negativity (P/N) in team interaction. By knowing the P/N ratio it is possible to run the nonlinear dynamics model that will portray what types of dynamics are possible for a team. These dynamics are …
Fredrickson, B. L., & Losada, M. F. (2005). Positive affect and the complex dynamics of human flourishing. American psychologist, 60(7), 678.
The hypothesis tested in this article was motivated, in part, by the nonlinear dynamic model introduced in Losada (1999) and advanced in Losada and Heaphy (2004) and herein (Fredrickson & Losada, 2005). This model has since been called into question (Brown, Sokal, & Friedman, 2013). Losada has chosen not to defend his nonlinear dynamic model …
Oettingen, G., Pak, H. J., &Schnetter, K. (2001). Self-regulation of goal-setting: Turning free fantasies about the future into binding goals. Journal of personality and social psychology, 80(5), 736.
Fantasy realization theory states that when people contrast their fantasies about a desired future with reflections on present reality, a necessity to act is induced that leads to the activation and use of relevant expectations. Strong goal commitment arises in light of favorable expectations, and weak goal commitment arises in light of unfavorable expectations. To …
Okereke, O. I., Prescott, J., Wong, J. Y., Han, J., Rexrode, K. M., & De Vivo, I. (2012). High phobic anxiety is related to lower leukocyte telomere length in women. PloS one, 7(7), e40516.
Background Chronic psychological distress has been linked to shorter telomeres, an indication of accelerated aging. Yet, little is known about relations of anxiety to telomeres. We examined whether a typically chronic form of anxiety – phobic anxiety – is related to telomere length. Methodology/Principal Findings Relative telomere lengths (RTLs) in peripheral blood leukocytes were measured …
Ahola, K., Sirén, I., Kivimäki, M., Ripatti, S., Aromaa, A., Lönnqvist, J., & Hovatta, I. (2012). Work-related exhaustion and telomere length: a population-based study. PLoS one, 7(7), e40186.
Background Psychological stress is suggested to accelerate the rate of biological aging. We investigated whether work-related exhaustion, an indicator of prolonged work stress, is associated with accelerated biological aging, as indicated by shorter leukocyte telomeres, that is, the DNA-protein complexes that cap chromosomal ends in cells. Methods We used data from a representative sample of …
