The article discusses the case of Microsoft's Twitter chatbot Tay that “turned into a Nazi” after less than 24 hours from its release on the Internet. The first section presents a brief recapitulation of Alan Turing's proposal for a test for artificial intelligence and the way it influenced subsequent discussions in the philosophy of mind. In the second section, I offer a few arguments appealing for caution regarding the identification of an accomplished chatbot as a thinking being. These are motivated principally by Ludwig Wittgenstein's discussions of mind and soul and by some Wittgensteinian philosophers' criticisms of AI endeavours. I will try to show that it is very difficult, if not impossible, to make sense of AIs such as chatbots as thinking beings, rather independently of their technical perfection and accomplishment. In the third section, the case of the “Nazi chatbot” Tay will offer me material for some light to be shed on the peculiar (primitive) character of our interconnected concepts of thinking, soul and person and on the importance of their further ramified connections. 相似文献

This paper focuses on compost use in overpasses and underpasses for wild animals over roads and other similar linear structures. In this context, good quality of compost may result in faster and more resistant vegetation cover during the year. Inter alia, this can be interpreted also as reduction of damage and saving lives. There are millions of tones of plant residue produced every day worldwide. These represent prospective business for manufacturers of compost additives called “accelerators”. The opinions of the sale representatives’ with regards to other alternatives of biowaste utilization and their own products were reviewed. The robust analyzes of several “accelerated” composts revealed that the quality was generally low. Only two accelerated composts were somewhat similar in quality to the blank sample that was produced according to the traditional procedure. Overlaps between the interests of decision makers on future soil fertility were weighed against the preferences on short-term profit. Possible causes that allowed the boom of these underperforming products and the possible consequences are also discussed. Conclusions regarding the ethical concerns on how to run businesses with products whose profitability depends on weaknesses in the legal system and customer unawareness are to follow. 相似文献

Behavioral inhibition (BI) discourages children from interacting, predisposing them to isolation, social anxiety, and depression. We have created the Behavioral Inhibition Scale for Children Aged 3 to 6 (BIS 3-6) to detect this trait early. Parents and teachers of 365 preschoolers completed different versions of the BIS 3-6 and provided measures of psychopathology. Both versions are structured into 1 factor that explains over 40% of total variability and displays excellent internal consistency (α = .95). The moderate correlations with measures of internalizing symptoms (r = .50) and nonexistent correlations with externalizing measures suggest adequate convergent and discriminant validity. A new scoring system is proposed. 相似文献

This article examines cultural differences in how people value future and past events. Throughout four studies, the authors found that European Canadians attached more monetary value to an event in the future than to an identical event in the past, whereas Chinese and Chinese Canadians placed more monetary value to a past event than to an identical future event. The authors also showed that temporal focus-thinking about the past or future-explained cultural influences on the temporal value asymmetry effect. Specifically, when induced to think about and focus on the future, Chinese valued the future more than the past, just like Euro-Canadians; when induced to think about and focus on the past, Euro-Canadians valued the past more than the future, just like Chinese. 相似文献

Processes of proactive interference were explored using the pigeon as a model system of memory. This study shows that proactive interference extends back in time at least 16 trials (and as many minutes), revealing a continuum of interference and providing a framework for studying memory. Pigeons were tested in a delayed same/different task containing trial-unique pictures. On interference trials, sample pictures from previous trials reappeared as test pictures on different trials. Proactive-interference functions showed greatest interference from the most recent trial and with the longer of two delays (10 s vs. 1 s). These interference functions are accounted for by a time-estimation model based on signal detection theory. The model predicts that accuracy at test is determined solely by the ratio of the elapsed time since the offset of the current-trial sample to the elapsed time since the offset of the interfering sample. Implications for comparing memory of different species and different types of memory (e.g., familiarity vs. recollection) are discussed. 相似文献

The psychometric properties of a Spanish version of the Muscle Appearance Satisfaction Scale (MASS; Mayville, Williamson, White, Netemeyer, & Drab, 2002) were examined using a sample of five hundred and sixty-one male weightlifters. Exploratory and confirmatory factor analyses suggested that the 19-item Spanish version of the MASS called the Escala de Satisfacción Muscular (ESM), was represented by five subscales similar to the original MASS. Internal consistency of the measure was good (α=.86-.95), and various measures of construct validity indicated that the ESM may be a useful measure of Muscle Dysmorphia symptoms among Spanish speaking populations. 相似文献

ResumenCon objeto de profundizar en algunos aspectos que hacen de la perspectiva textual un factor de la coherencia del discurso, se consideró la posibilidad de que, cuando concurre una alta complejidad retórica, la manipulación de la identidad del enunciante afectaría a la comprensión de los Ss, siempre que se mantuviera la facilitación contextual.Para probar esta hipótesis se elaboraron dos diseños experimentales. En el primero, un factorial 3 x 2, en el que los materiales eran fragmentos narrativos, se emplearon como medidas las respuestas a un cuestionario de comprensión, los tiempos de lectura, los tiempos de reacción a los ítems del cuestionario, el tiempo de demora en la respuesta, la valoración de la dificultad del texto y la atribución de textualidad. En el segundo diseño se presentaron, a tres grupos seleccionados al azar, frases independieras y aleatorizadas tomadas de los fragmentos del diseño anterior. En este caso se registraron las tres medidas temporales ya mencionadas y la identificación del enunciante. En total participaron 216 estudiantes de 3.° de BUP, mitad hombres y mitad mujeres, cuyas edades oscilaban entre dieciséis y veinte años. En ambos casos los aparatos empleados fueron una llave vocal conectada a un proyector de diapositivas, cuyo flujo era controlado por un programador de secuencias temporales con resolución de milisegundos.En el primer diseño nuestra hipótesis se confirmo (α-.01) para uno de los grupos (Facilitación contextual y constancia de la identidad del enunciante), al tiempo que la demora covarió con la atribución de textualidad (α =.01 y α=.05, según los grupos). En el segundo diseño no se encontraron diferencias significativas. Estos resultados son interpretados como indicios de la existencia de esquemas estilísticos. Además se discuten distintos aspectos de la función pragmática del estilo y de las características de su procesamiento. 相似文献

Model building or model selection with linear mixed models (LMMs) is complicated by the presence of both fixed effects and random effects. The fixed effects structure and random effects structure are codependent, so selection of one influences the other. Most presentations of LMM in psychology and education are based on a multilevel or hierarchical approach in which the variance-covariance matrix of the random effects is assumed to be positive definite with nonzero values for the variances. When the number of fixed effects and random effects is unknown, the predominant approach to model building is a step-up method in which one starts with a limited model (e.g., few fixed and random intercepts) and then additional fixed effects and random effects are added based on statistical tests. A model building approach that has received less attention in psychology and education is a top-down method. In the top-down method, the initial model has a single random intercept but is loaded with fixed effects (also known as an “overelaborate” model). Based on the overelaborate fixed effects model, the need for additional random effects is determined. There has been little if any examination of the ability of these methods to identify a true population model (i.e., identifying the model that generated the data). The purpose of this article is to examine the performance of the step-up and top-down model building approaches for exploratory longitudinal data analysis. Student achievement data sets from the Chicago longitudinal study serve as the populations in the simulations. 相似文献

A nearly abrupt coarsening of grains is observed in a newly developed Fe–Al–O ultra-fine-grained nanocomposite with a significant volume fraction (4%) of alumina nano-precipitates. The microstructure of the alloy was analysed in different states (as-received and annealed) by means of scanning electron microscopy, transmission electron microscopy (TEM) and hardness. The initial grain size 150–200 nm increases up to 50 μm during annealing 1000 °C/8 h and thereafter demonstrates saturation. A linear correlation between volume fraction of coarse grains and hardness was found. It was identified by TEM that alumina nano-precipitates stabilize the dislocation microstructure against recovery very effectively and the grain coarsening is due to fast growth of very few dislocation free grains. Thus, the observed grain coarsening has the attributes of static recrystallization. 相似文献
