A fundamental issue in the design and the interpretation of experimental studies of perception relates to the question of whether the participants in these experiments could perform the perceptual task assigned to them using another feature, or cue, than that intended by the experimenter. An approach frequently used by auditory- and…

Two experiments examined cross-trial positional priming (V. Maljkovic & K. Nakayama, 1994, 1996, 2000) in visual pop-out search. Experiment 1 used regularly arranged target and distractor displays, as in previous studies. Reaction times were expedited when the target appeared at a previous target location (facilitation relative to neutral…

Reports a series of experiments that give evidence for retention of information about color in very short-term visual memory, commonly termed "iconic memory". (Author)

Sense of direction was studied as a verbal expression of people's estimation of their own spatial orientation ability, rather than as a special mental faculty. Relates sense of direction to cognitive ability and to self concept. (Editor/RK)

Investigations of the relation between judged length and measured length have concentrated on determining the form of the psychophysical function. The process by which the observer arrives at his judgment has not been described. An exploratory experiment was carried out in an attempt to identify the process. (Author)

Attempts to replicate Gogel's (1972) observations with points of light and examines in addition whether the same results would be obtained if the binocularly nearer object was made visually more massive than the farther object and if the residual oculomotor cues were varied to produce different values of the reference distance. (Author/RK)

Human visual recognition on the basis of shape but regardless of size was investigated by reaction time methods. Results suggested two processes of size scaling: mental-image transformation and perceptual-scale transformation. Image transformation accounted for matching performance based on visual short-term memory, whereas scale transformation…

The possibility that subjective contours are an artifact of brightness contrast was explored. Concludes that subjective contour and brightness contrast are distinct perceptual phenomena but share a dependency on the processing of edge information transmitted through the achromatic channels of the visual system. (Editor/RK)

Explores the possibility that measurable individual differences in hypnotic susceptibility or the ability to attend selectively to informational cues may account for a portion of the variability found in several types of geometrical visual illusions. (Author/RK)

Attempts to provide empirical evidence for a functional correspondence between perception and imagination. Includes a perceptual-control condition in examining visual memory and imagery. (Author/RK)

Measures the phenomenal and the functional durations of visual stimuli differing in informational value. (Author/RK)

Compared five distinct classes of models of how people judge the relative sizes of named objects. Four basic experiments were all concerned with the amount of time necessary to decide which of two named things is larger. (Editor/RK)

Two experiments examined the effect of concurrently holding 0, 2, 4, or 6 nouns in memory on the recognition of visual stimuli briefly presented to the left or right visual fields. (Editor)

A familiarity effect in these experiments is defined as a subject's ability to respond more rapidly to a familiar stimulus than to an unfamiliar stimulus. Evidence indicates that familiarity does not affect an initial encoding process, but it can affect a comparison process. (Editor/RK)

Two theories of comparative judgment were compared across four experiments on their ability to explain the Baldwin figure, a focal line whose apparent length is affected by square boxes at or near its endpoints. (Editor)
