Recent studies have reported that vision can enhance tactile perception, even in patients with somatosensory deficits. However, it is unclear in these previous studies whether visual input truly enhances detection of tactile stimuli or induces a higher propensity for reporting touch by changing response criteria. In this study, we demonstrate in neurologically normal subjects that in addition to small increases in tactile sensitivity when a non-informative, suprathreshold visual stimulus is presented, there are highly consistent changes in response criteria for reporting touch with vision, even when no tactile stimulus is delivered. These results suggest that some of the previously reported enhancements of touch from vision may rather be a consequence of strategic sensory encoding processes that rely upon the typical correlations between multisensory events.
Although knowledge of the biological aspects of obesity is increasing very rapidly, psychological approaches are increasingly in demand. Psychological theory and research concerning the emotional and cognitive impacts of being obese, the psychological causes involved in obesity, and the psychological elements of treatment and motivations for treatment are requested. There is no clear separation between the psychological factors that function as causes of obesity and the psychological effects of obesity. Rather, they appear to be related in a circle of interconnectedness. This is important to keep in mind when seeking ways to motivate and support obese patients.
