An Empirical Test of Formal Equivalence between Emmert's Law and the Size-Distance Invariance Hypothesis
Emmert's law and the size-distance invariance hypothesis have been said to be formally equivalent, provided that Emmert's law means that the perceived size of an afterimage is proportional to the perceived distance of the projected surface of the afterimage....
An Immunochemical Approach to Model and Long-Term Suppression of Depressive and Anxiety Behavior
The inhibitor of monoaminooxydase isatin and the ligand of B-receptors cholecystokinin-4 play a significant role in the suppression and induction of depressive and anxiety states. We induced the formation of auto-antibodies to these compounds against...
Cardiovascular Reactivity in Hypertensives: Differential Effect of Expressing and Inhibiting Emotions during Moments of Interpersonal Stress
This study investigated cardiovascular reactivity of hypertensive adults during periods of emotional stress. Two types of instructions were given at different moments, to the same subject, either to express or to suppress feelings during role-play. Expressing,...
Conscious and Unconscious Sensory Inflows Allow Effective Control of the Functions of the Human Brain and Heart at the Initial Ageing Stage
The authors of the present article based their assumption on the concept that the sensory systems are the "windows to the brain" through which various functions of the human organism can be controlled. Comprehension of the fundamental mechanisms of the...
Distance Perception in a Natural Outdoor Setting: Is There a Developmental Trend to Overconstancy?
The main purpose of the present study was to investigate whether in natural environment, using very large physical distances, there is a trend to overconstancy for distance estimates during development. One hundred and twenty-nine children aged 5 to...
Does Energy Expenditure Affect the Perception of Egocentric Distance? A Failure to Replicate Experiment 1 of Proffitt, Stefanucci, Banton, and Epstein (2003)/Reply to Hutchison and Loomis/Reply to Proffitt, Stefanucci, Banton, and Epstein/A Final Reply to Hutchison and Loomis
Jeffrey J. Hutchison and Jack M. LoomisUniversity of CaliforniaIn a series of recent studies, Proffitt and his colleagues have reported that the perceived distance to a target is influenced by the energy expenditure associated with any action, such as...
Factor Structure of Items from the Personality Adjective Check List in a Sample of Normal Adolescents
We present the results of a principal-components analysis of the Personality Adjective Check List (PACL) at the item level, rather than at the scale level. The PACL was constructed by Strack (1987) to evaluate the personality scales proposed by Millon...
Fathers and Gender Traditionalism: Perception of Inequality and Life Roles
Men's discourse about the paternal role is changing significantly. Despite the fact that men still perceive themselves as being responsible for the family's economical protection and the children's discipline, they face increasing demands for more involvement...
Geometrical Structures of Photographic and Stereoscopic Spaces
Two experiments were conducted to investigate the geometrical structures of photographic and stereoscopic spaces. In Experiment 1, it was investigated how accurately photographic space reproduces real physical space, and the geometrical structure of...
Influence of the Instructions on the Performance and Establishment of Memorization Strategies in Space Judgments
Studies of visual space perception have been assuming that people have an internal representation of the physical space that surrounds them. A variety of psychophysical procedures has been used in an attempt to measure the properties of visual space....
Introduction
The decision to devote this section to Spatial Vision and Visual Space was taken two years ago (October 2004) in Coimbra (Portugal), during the annual meeting of the ISP (International Society for Psychophysics). Three researchers who participated in...
Is Sexual Attraction Independent of the Instrumental and Expressive Traits?
Sexual attraction is an essential part of sex, just as the instrumental and expressive traits are the mainstay of gender. Various hypotheses concerning the dimensionality and independence versus dependence/overlapping of these core entities were tested....
Lightness Compression and Hue Changes
Two experiments were performed to relate the Bezold-Brücke (B-B) and lightness compression effects. The first used a calibrated screen to present an achromatic luminance staircase. In addition, it reproduced, the methodology and the essential aspects...
Narrow-Band 1, 2, 3, 4, 8, 16, 24, 32, 48, 64, and 96 Cycles/360° Angular Frequency Filters
We measured human frequency response functions for eleven angular frequency filters using a forced-choice procedure in a supra-threshold summation paradigm. Each of the eleven functions of 17 experimental conditions was measured 4-9 times among 12 observers....
One-Dimensional and Multi-Dimensional Studies of the Exocentric Distance Estimates in Frontoparallel Plane, Virtual Space, and Outdoor Open Field
The aim of this study is twofold: on the one hand, to determine how visual space, as assessed by exocentric distance estimates, is related to physical space. On the other hand, to determine the structure of visual space as assessed by exocentric distance...
Psychopathological Symptoms, Social Skills, and Personality Traits: A Study with Adolescents
The purpose of this study is two-fold: (a) to study the concomitant relationships between psychopathological symptoms, cooperation, social skills, and other personality traits; and (b) to identify the predictive variables of psychopathological symptoms....
Psychophysiological Training of Operators in Adaptive Biofeedback Cardiorhythm Control
A new individual computerized technique for psychophysiological training of operators before performing psychomotor activity on a computer model (psychomotor concentration and spatial orientation test) was developed. Qualitative criteria for the prediction...
The Effect of Content and Physical Properties of Affective Pictures on Emotional Responses
The aim of this research was to study the influence of both the emotional content and the physical characteristics of affective stimuli on the psychophysiological, behavioral and cognitive indexes of the emotional response. We selected 54 pictures from...
The Effect of White-Noise Mask Level on Sinewave Contrast Detection Thresholds and the Critical-Band-Masking Model
It is known that visual noise added to sinusoidal gratings changes the typical U-shaped threshold curve which becomes flat in log-log scale for frequencies below 10c/deg when gratings are masked with white noise of high power spectral density level....
Visual Distance Estimation in Static Compared to Moving Virtual Scenes
Visual motion is used to control direction and speed of self-motion and time-to-contact with an obstacle. In earlier work, we found that human subjects can discriminate between the distances of different visually simulated self-motions in a virtual scene....
