   Abstract = {A central theoretical assumption in classical psychophysics
             is that people judge the intensities of stimulus elements;
             for example, observers directly report the loudness of a
             tone or the intensity of a shock. A methodological
             assumption in classical psychophysics is that averaged data
             demonstrate this theoretical view. It is shown in this
             article that both assumptions are wrong and that the
             psychophysical laws of Weber, Fechner, and Stevens are not
             general. Rather, psychophysical judgments are made in
             relation to contexts and memories, measures of which provide
             new information about psychophysical judgments and new
             understandings of channel capacity, the local-global
             distinction, and the source of noise in signal detection
             theory.},

   Abstract = {Choice is modeled by game theory through analyses of the
             structure of a game situation. However, at least some
             choices, such as those in games that have more than one
             rational solution, are difficult to address under standard
             game theory. We investigated choice in a simple
             multiple-equilibrium game, Wolf's Dilemma, and found that
             choice depends on both structural components of the game,
             such as the number of opponents, and non-structural
             components, such as judgments about opponents' likely
             choices. Significant effects of trial-to-trial sequence were
             identified. We conclude that game theoretic methods cannot
             deal with multiple and equilibrium games in the absence of a
             psychological understanding of choice, and that
             psychological measures are required to predict performance
             in such games. © 2000 Elsevier Science B.V. All rights

   Title = {Range effects of an irrelevant dimension on
             classification.},
   Journal = {Perception & psychophysics},
   Volume = {61},
   Number = {8},
   Pages = {1624-1645},
   Year = {1999},
   Month = {November},
   ISSN = {0031-5117},
   url = {http://www.ncbi.nlm.nih.gov/pubmed/10598475},
   Abstract = {In univariate classification tasks, subjects sort stimuli on
             the basis of the only attribute that varies. In orthogonal
             classification tasks, often called filtering tasks, there
             additionally are trial-to-trial variations in irrelevant
             attributes that the subjects are instructed to ignore.
             Performance is generally slower in filtering tasks than in
             univariate control tasks. We investigated this slowing in
             experiments of how the range of irrelevant trial-to-trial
             variation affects responses in pitch/loudness classification
             tasks. Using two levels of pitch and of loudness as stimuli,
             Experiment 1 replicated prior work showing that responses
             are slowed more when the range of the irrelevant dimension
             is made larger. Also in Experiment 1, sequential analyses
             showed that response time depends both on sequence and on
             the stimulus set independent of sequence. Experiments 2 and
             3 used several levels on the irrelevant dimension and showed
             that responses to categorize loudness are slowed more by
             larger trial-to-trial pitch differences, but only on trials
             when the response repeats. When the response changes,
             performance is essentially unaffected by trial-to-trial
             irrelevant variation. This interaction supports the
             conclusion that slowed average performance in orthogonal
             classification tasks, which is known as Garner interference,
             is not due to difficulties that subjects have in filtering
             stimulus attributes. It is due to how subjects process
             successive stimulus differences. We call for more frequent
             reports of sequential analyses, because these can reveal
             information that is not available from data
             averages.},

   Title = {The micfogenesis of geometrical illusions: contextdependent
             changes in visiual sensitivity and the muller-lyer
             effect},
   Journal = {Investigative Ophthalmology and Visual Science},

   Month = {December},
   Abstract = {Purpose, We analyze the influence of visual contexts which
             resemble the Muller-Lyer configuration on the detectability
             of a target stimulus. Methods. Six adult subjects were
             instructed to detect the occurrence of a target while the
             target and the context were briefly flashed periodically.
             During each trial the target was presented alone, in
             conjunction with the context, or neither target nor context
             were presented. The target occurred randomly at one of four
             contrasts; the context (outward or inward arrowhead) was
             always presented at high contrast. We measured the detection
             ratio (denned as proportion correct detections) for all four
             target contrasts in the following conditions: (a) target
             alone; (b) target and outward arrowhead; (c) target and
             inward arrowhead. We varied the angle between the arrowhead
             fins and the distance between the arrowhead and the target.
             Results. Target detection is facilitated by the inward
             arrowhead and suppressed by the outward arrowhead. The
             amount of facilitation and suppression increases
             monotonically with the decrease in arrowhead angie, but it
             diminishes as target contrast increases. When the distance
             between target and context increases, both inhibitory and
             excitatory effects diminish drastically in strength. If
             distance is further increased the influence of the outward
             arrowhead changes from suppression to facilitation. The
             inhibitory and excitatory effects are amplified if a
             symmetric arrowhead is added on the other end of the target.
             All observed variations in detection ratio match
             qualitatively the lesults obtained with the Mulier-Lyer
             illusion, in which a bar appears long or short when it is
             flanked by inward or outward arrowheads. Conclusions, (a)
             Previous results (e.g., Kapadia et al., 1995; Polat and
             Sagi, 1994) reported facilitory effects of the surround. We
             found that as a function of surround orientation and spatial
             offset there is a continuum of surround modulations ranging
             from strong inhibition to strong excitation; (b) Our
             findings are consistent with short and long-range receptive
             field interactions in primary visual cortex and suggest a
             physiological basis for surround modulation; (c) The
             Muller-Lyer extent illlusion is correlated with target
             detectability. We suggest that detectability and perceived
             extent are caused by the same mechanism.},

   Abstract = {Psychophysical scaling models of the form R = f(I), with R
             the response and I some intensity of an attribute, all
             assume that people judge the amounts of an attribute. With
             simple biases excepted, most also assume that judgments are
             independent of space, time, and features of the situation
             other than the one being judged. Many data support these
             ideas: Magnitude estimations of brightness (R) increase with
             luminance (I). Nevertheless, I argue that the general model
             is wrong. The stabilized retinal image literature shows that
             nothing is seen if light does not change over time. The
             classification literature shows that dimensions often
             combine to produce emergent properties that cannot be
             described by the elements in the stimulus. These and other
             effects cannot be adjusted for by simply adding variables to
             the general model because some factors do not combine
             linearly. The proposed alternative is that people initially
             judge the entire stimulus - the object in terms of its
             environment. This agrees with the constancy literature that
             shows that objects and their attributes are identified
             through their relations to other aspects of the scene. That
             the environment determines judgments is masked in scaling
             studies where the standard procedure is to hold context
             constant. In a typical brightness study (where different
             lights are presented on the same background on different
             trials) the essential stimulus might be the intensity of the
             light or a difference between the light and the background.
             The two are perfectly confounded. This issue is examined in
             the case of audition. Judgments of the loudness of a tone
             depend on how much that tone differs from the previous tone
             in both pitch and loudness. To judge loudness (and other
             attributes) people first seem to process the stimulus object
             in terms of differences between it and other aspects in the
             situation; only then do they assess the feature of interest.
             Psychophysical judgments will therefore be better
             interpreted by theories of attention that are based in
             biology or psychology than those (following Fechner) that
             are based in classical physics.},

   Abstract = {We propose that the correct interpretation of the moon
             illusion is that the zenith moon appears small, not that the
             horizon moon appears large. This illusion is caused by the
             visual gap between the observer and the overhead moon.
             Because of the gap, the observer has no or little optical
             information about the distance of the moon. This results in
             empty field myopia where the moon is neurally, although not
             necessarily cognitively, processed as being at about arm's
             length. When the moon is seen on the horizon, there usually
             is optical information about distance. That results in
             reduced accommodation, and so the moon is processed as at a
             greater distance. Consistent with the size-distance-invariance
             hypothesis, the moon is then judged as large. This is a
             specific example of the more general fact that all distant
             objects appear small in the absence of a stimulus for
             accommodation to be distant. This outcome produces the toy
             illusion.},

             Subjects completed a questionnaire regarding work habits and
             certain life-style aspects. They were shown photographs of
             varying spatial frequencies to identify the adapting

             routine use of VDTs was 19.1%. The adapting stimulus was the
             repeating character lines of the VDT. No aspect of
             life-style investigated appeared to predispose an individual
             to develop the ME. Those subjects who developed the ME did

   Abstract = {The perception of gradually changing luminance distributions
             was investigated. Luminance changed across the radius of a
             disk by a linear, quadratic, or cubic function with varying
             magnitudes. Subjects selected matching luminances for the
             inner and outer edges of each stimulus. The threshold for
             reporting that the inner and outer matches were different
             occurred at approximately 20% contrast between those
             regions. This threshold did not vary with the particular
             function which described the luminance distribution.
             Further, as the magnitude of luminance change across the
             stimulus increased, subjects judged the inner and outer
             edges to differ more in brightness. Matching luminances also
             depended upon the background configuration with greater
             differences perceived across the disk radius when the
             surround and center dot of the stimulus were of opposite,
             rather than the same, luminance. These results indicate that
             models of brightness must consider all luminance changes in
             the stimulus, not just changes of a particular type such as
             second differences or changes at a luminance
             step.},

   Abstract = {Subjects judge successive stimuli to be overly similar in
             psychophysical scaling tasks. This is called assimilation.
             They also tend to judge each stimulus as overly different
             from more previous events. This is called contrast. To
             examine a two-stage linear model of these sequence effects,
             we asked subjects to judge the relative intensity of
             successive tones. In support of the model, responses again
             depended lawfully on prior events. These memory effects
             occur in a variety of scaling tasks and are consistent with
             two assumptions: (a)Successive events assimilate in memory,
             and (b) subjects compare each stimulus to a collection of
             memories of prior events to generate a response. The
             trial-by-trial analysis used to test the model also showed
             that even in magnitude-estimation studies, equal stimulus
             ratios do not result in equal response ratios, except on
             average. This article suggests that examinations of
             trial-by-trial performance might be useful in studying
             memory and judgment processes.},

             the only information these people use to identify musical
             notes; piano notes are complex waveforms or patterns, sine
             waves are not complex. Musically trained people who do not

   Abstract = {Results of a study with 77 kindergartners, 24 1st graders,
             21 2nd graders, and 6 college students show that small
             graphic changes made in normal letters of the alphabet
             changed the similarity relations among those letters. All Ss
             classified letters of this distinctive font faster and with
             fewer errors than they classified normal letters. It is
             shown that it is not features alone but relations between
             features within letters, and relations between letters in
             the stimulus set, that determine how difficult any
             particular letter is to classify. The advantage of the
             distinctive font is such that many children had less
             difficulty classifying distinctive letters into bins labeled
             with normal letters than doing the conceptually easier
             match-to-sample task of placing normal letters into bins

   Abstract = {24 undergraduates recalled the names of as many animals,
             birds, foods, or cold foods as they could in 15- or 30-min
             sessions. In each task, the rate of item production
             decreased with increasing time, and semantically related
             items were produced in spurts over time. Results are
             consistent with a proposed 2-stage model in which people (a)
             search for semantic fields and (b) produce whatever items
             are encountered when a field is located. It is proposed that
             time between clusters increases hyperbolically in these
             tasks, reflecting the search for semantic fields, and that
             the time between items within clusters, and the number of
             items in each cluster, are independent of time in the task,
             reflecting the production of items in discovered fields. On
             these bases an algorithm is introduced that partitions
             clusters by the temporal patterning between words in the
             protocols. The temporally-based algorithm provides a
             description of the data that highly correlates with the
             semantic structure as depicted by judges' ratings. These
             correlated temporal and semantic measures may reflect
             aspects of the search process and the structure of memory.

   Abstract = {In a focusing task, people respond positively to one
             stimulus and negatively to all other stimuli that occur. The
             task has been called focusing in recognition of the
             possibility that only the target stimulus is relevant to
             performance, and that what people do is to focus on some
             aspect of the target, such as its configuration. The present
             study used eight patterns, and people focused on each
             pattern in eight different experimental conditions. The
             stimulus set was selected to have good patterns (according
             to symmetry, subjective goodness, and free classification
             measures) that were similar to each other (according to
             similarity judgments) and poor patterns that were dissimilar
             from one another and from the good patterns. The results
             were that the good patterns were difficult (speed and
             accuracy) to classify, and the poor patterns were easy. The
             similarity between the target pattern and the other patterns
             in the total set, i.e., the context of each focused
             stimulus, predicted performance. These results support the
             idea that similarity judgments measure relevant aspects of
             context and that the effects of context on performance
             should not be overlooked. © 1979 Psychonomic Society,

   Abstract = {Temporal coding theories of color vision suggest
             explanations of flicker-induced subjective colors such as
             those that appear on Benham's disk. If color blindness were
             due simply to photopigment anomalies, then subjective colors
             might be elicited by central patterns of neural activity in
             color-blind observers that mimic those which the cones
             normally produce in colornormal observers. We had
             color-normal and color-blind observers scale subjective
             colors like those on Benham's disk for similarity. The
             inferred color spaces for six normal observers resembled the
             familiar hue circle, but the spaces for five
             red-green-deficient observers were compressed along the
             red-green axis. This is consistent with the position that
             flicker colors are due to retinal processes, and suggests
             that color blindness may involve variations of the central
             nervous system in addition to photopigment anomalies. ©

             The results of the filtering and condensation tasks and the

             processing model of stimulus identification in which
             discriminability is related to psychological distances

             rectangles from linearly correlated and from equally
             redundant scattered sets of 6 stimuli. The holistic model
             was confirmed; parallel decision model predictions were

   Abstract = {2 studies with 3 undergraduates each investigated the
             effects of previous stimuli on responses in an absolute
             judgment of loudnesses situation when feedback was and was
             not provided. Whether or not information feedback was
             provided, responses were assimilated to the value of the
             immediately previous stimulus in the series. The effects of
             stimuli more than 1 trial back in the sequence depend on the
             presence or absence of feedback. When the entire stimulus
             scale was shifted up or down to 5 db. from the level on the
             previous day, a substantial shift occurred in the constant
             error of judgment in the direction of the scale shift,
             providing evidence that a relatively long-term (24-hr)
             memory process was being used in the judgment situation.
             None of the currently available models is adequate to
             account for both these results and those of earlier studies.
             The form of the sequential dependencies observed may depend
             at least partially on the presence or absence of an
             identification function from stimuli to responses. (18 ref.)

   Abstract = {The effects of preceding stimuli on the judgments of current
             stimuli were examined in a study using absolute judgments of
             loudness with feedback. It was found that the response on a
             given trial was dependent on the stimuli in the preceding
             sequence of at least five trials. Both assimilation and
             contrast effects were observed. The form of the dependency
             of a response on a prior stimulus was a function of the
             ordinal position of the stimulus in the preceding sequence
             of trials. The stimulus on the immediately preceding trial
             had an assimilative effect on the response and preceding
             stimuli two to five trials removed all showed a contrast
             effect on a given response. The extent to which these
             preceding stimuli contributed to the contrast effect was an
             increasing function of their recency. The reversal of the
             dependency of the response, from assimilation to the
             stimulus one trial back, to contrast with the stimuli two
             and more trials back, indicates a unique function of the
             immediately preceding stimulus in this task. Since there was
             a reduction in the variance of responses to those stimuli
             similar in value to the immediately preceding stimulus, it
             is proposed that the stimulus and feedback on the last trial
             were remembered and used asa standardin judging the
             presented stimulus. A model is presented in which it is
             assumed that the memory of the magnitude of the immediately
             preceding stimulus is contaminated in specified ways by
             prior stimuli in the series. The empirical findings of
             assimilation and contrastare expected consequences of the
             proposed memorial processes. © 1968 Psychonomic

             patterned stereograms is made from the knowledge of two
             monocular events: contrast effects associated with contours
             and phasic local adaptation. It is argued that the percepts
             resulting from these monocular processes are combined simply
             by some more central process and that a suppression
             mechanism may not be necessary to account for contour
             rivalry. Predictions were tested in three experiments and
             the results tend to support the argument given. © 1967

             make 10 times as many errors as the most accurate. Fast
