Apparent Problem

The supposed problem of perceptual error, including illusion and hallucination, has led most theories of perception to deny formulations of direct realism. The standard response to this apparent problem adopts the mistaken presupposition that perception is indeed liable to error. However, the prevailing conditions of observation are themselves elements of perceptual representation, functioning in the manner of predicate modifiers. They ensure that the predicates applied in perceptual representations do indeed correctly attribute properties that perceived physical objects actually instantiate. Thus, perceptual representations are immune to misrepresentation of the sort misguidedly supposed by the spurious problem of perceptual misrepresentation. Granted the possibility that perceptual attribution admits of predicate modification, it is quite possible that perceptual experience permits both rudimentary and sophisticated conceptualization. Moreover, such treatment of perceptual predication rewards by providing an account of aspect alteration exemplified by perception of ambiguous stimuli.

Perseverative thinking (PT), or repetitive negative thinking, has historically been measured using global self-report scales. New methods of assessment are needed to advance understanding of this inherently temporal process. We developed an intensive longitudinal method for assessing PT. A mixed sample of 77 individuals ranging widely in trait PT, including persons with PT-related disorders (generalized anxiety disorder, major depression) and persons without psychopathology, used a joystick to provide continuous ratings of thought valence and intensity following exposure to scenarios of differing valence. Joystick responses were robustly predicted by trait PT, clinical status, and stimulus valence. Higher trait perseverators exhibited more extreme joystick values overall, greater stability in values following threatening and ambiguous stimuli, weaker stability in values following positive stimuli, and greater inertia in values following ambiguous stimuli. The joystick method is a promising measure with the potential to shed new light on the dynamics and precipitants of perseverative thinking.
