Color-discrimination threshold determination using pseudoisochromatic test plates
2014
We produced a set of pseudoisochromatic plates for determining individual color-difference thresholds to assess test performance and test properties, and analyzed the results. We report a high test validity and classification ability for the deficiency type and severity level [comparable to that of the fourth edition of the Hardy–Rand–Rittler (HRR) test]. We discuss changes of the acceptable chromatic shifts from the protan and deutan confusion lines along the CIE xy diagram, and the high correlation of individual color-difference thresholds and the red–green discrimination index. Color vision was tested using an Oculus HMC anomaloscope, a Farnsworth D15, and an HRR test on 273 schoolchildr…
A Unified Theory of Psychophysical Laws in Auditory Intensity Perception.
2020
Psychophysical laws quantitatively relate perceptual magnitude to stimulus intensity. While most people have accepted Stevens's power function as the psychophysical law, few believe in Fechner's original idea using just-noticeable-differences (jnd) as a constant perceptual unit to educe psychophysical laws. Here I present a unified theory in hearing, starting with a general form of Zwislocki's loudness function (1965) to derive a general form of Brentano's law. I will arrive at a general form of the loudness-jnd relationship that unifies previous loudness-jnd theories. Specifically, the "slope," "proportional-jnd," and "equal-loudness, equal-jnd" theories, are three additive terms in the ne…
Coppie miste in Italia e in Spagna. Uno studio sui fattori che favoriscono il senso di comunità dei partner stranieri
2013
Lo scopo del presente contributo è stato quello di analizzare come l’identificazione etnica (ingroup ed outgroup) e la discriminazione percepita (come straniero o come partner di coppia mista) siano legati al senso di comunità (SdC) dei partner stranieri delle famiglie interculturali residenti in Spagna e in Italia. I risultati mostrano che in entrambi i gruppi l’identificazione con il proprio gruppo etnico-culturale non è associata al SdC. Inoltre, l’aumento della discriminazione percepita come coppia mista porta ad una diminuzione del senso di comunità e della soddisfazione di vita. The aim of this paper was to analyze how ethnic identification (ingroup and outgroup) and perceived discrim…
Zasada pozytywnej dyskryminacji mniejszości narodowych w ujęciu teoretycznym i praktyce ustrojowej
2018
CEL NAUKOWY: Celem artykułu jest zbadanie teoretycznych aspektów zasady pozytywnej dyskryminacji, ustrojowych uwarunkowań jej zastosowania w odniesieniu do mniejszości narodowych w Polsce oraz dziedzin, w których może być realizowana. PROBLEM I METODY BADAWCZE: Zagadnienie pozytywnej dyskryminacji znajduje się w obrębie zainteresowania przedstawicieli wielu nauk i idealnie wpasowuje się w koncepcję demokracji ujmowanej jako wartości, procedury i w sensie substancjalnym. Nie jest ona przy tym ochroną antydyskryminacyjną, lecz jej wsparciem, promotorem równości formalnej i faktycznej. W Polsce, choć odsetek mniejszości narodowych jest nikły, pozytywna dyskryminacja ma rangę zasady w Konstytuc…

Numerical Magnitude Affects Accuracy but Not Precision of Temporal Judgments
2021
A Theory of Magnitude (ATOM) suggests that space, time, and quantities are processed through a generalized magnitude system. ATOM posits that task-irrelevant magnitudes interfere with the processing of task-relevant magnitudes as all the magnitudes are processed by a common system. Many behavioral and neuroimaging studies have found support in favor of a common magnitude processing system. However, it is largely unknown whether such cross-domain monotonic mapping arises from a change in the accuracy of the magnitude judgments or results from changes in precision of the processing of magnitude. Therefore, in the present study, we examined whether large numerical magnitude affects temporal ac…
Selective breeding for endurance running capacity affects cognitive but not motor learning in rats
2012
The ability to utilize oxygen has been shown to affect a wide variety of physiological factors often considered beneficial for survival. As the ability to learn can be seen as one of the core factors of survival in mammals, we studied whether selective breeding for endurance running, an indication of aerobic capacity, also has an effect on learning. Rats selectively bred over 23 generations for their ability to perform forced treadmill running were trained in an appetitively motivated discrimination-reversal classical conditioning task, an alternating T-maze task followed by a rule change (from a shift-win to stay-win rule) and motor learning task. In the discrimination-reversal and T-maze …
La genitorialità nella coppia omoaffettiva
2020
Il saggio affronta il delicato tema della aspirazione alla genitorialità procreativa da parte delle coppie omoaffettive nel nostro ordinamento alla luce dei divieti legislativi e del diritto vivente, considerati nel quadro dei principi costituzionali di riferimento. Indica argomenti e possibili soluzioni ermeneutiche per affermare un diritto alla genitorialità e per offrire adeguata copertura giuridica alla posizione del nato. The essay deals with the delicate issue of the aspiration to procreative parenthood by homosexual couples in our legal system in the light of the relevant legislative prohibitions and the recent case-law, considered within the framework of the constitutional principle…
