This study assessed the ability of seven children to accurately judge relative durations of auditory and visual stimuli before and after participation in a language remediation program. The goal of the intervention program is to improve the children's ability to detect and identify rapidly changing auditory stimuli, and thereby improve their language-related skills. Children showed improved acc...

Although the body weight evaluation (e.g., normal or overweight) of others relies on perceptual impressions, it also can be influenced by other psychosocial factors. In this study, we explored the effect of task-irrelevant emotional facial expressions on judgments of body weight and the relationship between emotion-induced weight judgment bias and other psychosocial variables including attitude...

Statements of the form "Osorno is in Chile" were presented in colors that made them easy or difficult to read against a white background and participants judged the truth of the statement. Moderately visible statements were judged as true at chance level, whereas highly visible statements were judged as true significantly above chance level. We conclude that perceptual fluency affects judgments...

We ask whether the widely used direction of decision and direction of vote variables in the United States Supreme Court Judicial Database (USSCJD) are contaminated by confirmation bias, or have been affected by expectations about the likely effects of judicial preferences on case outcomes. Using a sample of generally comparable cases, we find evidence that the assignment of issue codes to these...

The perceived brightness of a gray patch depends on the surrounding context. For example, a medium-gray patch appears darker when placed on a bright background and brighter when placed on a dark background. Models to explain these effects are usually based on simple low-level mechanisms. A new set of brightness illusions cannot be explained by such models. In these illusions, the brightness per...

This article introduces 2 new sources of bias in probability judgment, discrimination failure and inhibition failure, which are conceptualized as arising from an interaction between error prone memory processes and a support theory like comparison process. Both sources of bias stem from the influence of irrelevant information on participants' probability judgments, but they postulate different ...

The chief executive officers (CEOs) of 96 multisite, U.S.-based hotel owner/operator companies were interviewed and asked to describe the dominant upcoming threats and opportunities they perceived for their segment. Responses converged in describing two major threats (overbuilding and economic downturn) but were far more divergent in descriptions of opportunities. This pattern may emerge from t...

Perceiving an external stimulus not only depends on the physical features of the stimulus, but also fundamentally on the current state of neuronal excitability, indexed by the power of ongoing alpha oscillations. Recent studies suggest that heightened excitability does not improve perceptual acuity, but biases observers to report the presence of a stimulus regardless of its physical presence. I...
