Relative distance of lights: An extension of Bugelski’s findings

Three lights in various orientations were presented to two trained Ss. The Ss adjusted the three lights until they appeared equidistant. The results supported earlier work of a similar nature, in that the higher light was perceived as closer and horizontal separation between lights produced no significant differences in depth settings. The phenomenon was shown to occur with monocular vision, fixated vision, large angular separation of the stimuli, and with different directions of regard with respect to the fixation point. The relationship to other research is discussed.     

NoA’s ark: Influence of the number of associates in visual word recognition

The main aim of this study was to explore the extent to which the number of associates of a word (NoA) influences lexical access, in four tasks that focus on different processes of visual word recognition: lexical decision, reading aloud, progressive demasking, and online sentence reading. Results consistently showed that words with a dense associative neighborhood (high-NoA words) were processed faster than words with a sparse neighborhood (low-NoA words), extending previous findings from English lexical decision and categorization experiments. These results are interpreted in terms of the higher degree of semantic richness of high-NoA words as compared with low-NoA words. 2008 Psychonomic Society, Inc. Author Note     

On the Expression of Emotions in Rembrandt’s Art

Rembrandt has been characterized as "the master of the passions of the soul". His painting production has always elicited the viewers' strong emotional responses. Τhese responses raise the question regarding why Rembrandt's work has been singled out as the quintessential example of the expression of emotions both during the 17th century, as well as in recent times. I will try to approach the issue through two different yet interconnected routes. First, I will explore the tools and terms through which the question of the expression of emotions in Rembrandt's oeuvre can be approached. Ancient rhetorical topoi, as well as ideas stemming from Dutch theater writers, drama and art theorists, scholars and art connoisseurs on the rendition of the emotions provide useful points of view. Secondly, I will approach the question by addressing certain stylistic and compositional solutions that Rembrandt suggested, which can be tied to current notions about lifelikeness and the beholder's empathy. Foremost among Rembrandt's aesthetic choices was his handling of light and of paint which accounts for a great deal of unfavorable criticism to his work during the 17th century. I would like to suggest that this handling of light and paint serves as Rembrandt's most important emotive vehicle and furthermore that it introduces us to the idea of wonder and the concept of the sublime in terms of which his depiction of emotions may be understood. Accordingly, I will try to establish an intellectual network in the 17th-century Netherlands for the sublime.     

Different senses of finitude: An inquiry into Hilbert’s finitism

This article develops a critical investigation of the epistemological core of Hilbert’s foundational project, the so-called the finitary attitude. The investigation proceeds by distinguishing different senses of ‘number’ and ‘finitude’ that have been used in the philosophical arguments. The usual notion of modern pure mathematics, i.e. the sense of number which is implicit in the notion of an arbitrary finite sequence and iteration is one sense of number and finitude. Another sense, of older origin, is connected with practices of counting concrete things, and a third sense is linked up with the immediate intuitive experience of multitudes of concrete things. Hilbert’s finitism is examined with respect to these differences, and it will be shown that there is a tendency to conflate the different senses of number and finitude, a tendency which has been a source of problems in the discussion of the foundations of mathematics and in the philosophy of logic and language.     

An extension of freud and jung’s theory of the relation of dream states to schizophrenia

The central model for both Sigmund Freud and Carl Gustav Jung for the generation of schizophrenia’s hallucinations and delusional system is described as the intrusion of nighttime dream states into the waking consciousness. In this theoretical exegesis, a rent or tear is made in the ego instated by strongly repressed aggressive impulses which then create a dream-world for the patient as they subsequently overwhelm ego defenses. A parallel between this mode of knowing and, for example, the regioning of Martin Heidegger in his Discourse on Thinking is brought forward. Since these modes of thought are analogical and metaphorical, analysis based on this similarity may provide for greater insight into the thought and perceptual disorders of schizophrenia. An understanding of this kind of thought process may then provide a bridge towards more effective therapeutic interventions. A distinction is made between thought processes, per se, and those causal factors of a biological nature.     

An Exploration of the Experience of Huntington’s Disease in Family Dyads: An Interpretative Phenomenological Analysis

Huntington’s disease (HD) is a hereditary, late onset, neurodegenerative disorder. Children of affected parents have a 50 % chance of inheriting HD. Research into the psychological consequences of HD for the family has focussed on individual family members, but little is known about the ways in which its impact is jointly experienced by members of these families. This is particularly important due to the hereditary nature of HD. To address this, the current study examined the experiences of dyads within affected families. Seven parent/adult child dyads were interviewed jointly about their experiences and relationships with their family and each other and interpretative phenomenological analysis was used to analyse the resultant data. Identified themes were: “A spectre hanging over us”: HD as a presence within the family, “Us against the world”: Protection, knowledge and control, and “That could be me in 50 years”: Cyclical changes in identity and role. These findings are examined in relation to previous research and indicate the need for an increased understanding of the needs of HD families. Clinical implications and suggestions for further research are discussed.     

On a variant of Stroop’s paradigm: Which cognitions press your buttons?

The Stroop effect typically refers to the fact that the time to identify the color of a visually presented word is affected by the relationship between the word and the color When the (irrelevant) word is semantically related to the color (e.g., the word green, presented in red) response time is slower than if the word is neutral or unrelated. One question that has been posed concerns whether semantics plays a role only when the task requires an explicit verbal response, or whether it also plays a role when the response is manual. Sharma and McKenna (1998) have reported that semantics plays a role only when the response is vocal. A reanalysis of their data shows that semantics also plays a role when manual responses are made.     

Forcing the issue: Little psychological influence in a magician’s paradigm

Forcing is usually described as the effect in which stage magicians covertly influence decisions made by spectators. The phenomenon has been subject to a number of recent articles and is typically placed within the context of social influence, priming, decision making, awareness, free will, and the science of magic. In the present paper I will argue that forcing researchers, when framing and describing the phenomenon, have exaggerated what magicians typically achieve with the technique. Specifically, the magician is said to influence and manipulate the spectator’s decision when in fact the vast majority of forces do not include any such influence. The consequence of this misrepresentation is that psychologists will be led to believe that the forcing phenomenon has more to contribute to priming and the psychology of influence than it actually does.     

Motion in the mind’s eye: Comparing mental and visual rotation

Mental rotation is among the most widely studied visuospatial skills in humans. The processes involved in mental rotation have been described as analogous to seeing an object physically rotate. We used functional magnetic resonance imaging of the whole brain and localized motion-sensitive hV5/MT1 to compare brain activation for stimuli when they were mentally or visually rotated. The results provided clear evidence for activation in hV5/MT1 during both mental and visual rotation of figures, with increased activation for larger rotations. Combined with the overall similarities between mental and visual rotation in this study, these results suggest that mental rotation recruits many of the same neural substrates as observing motion.     

Does prior knowledge facilitate the detection of visual targets in random noise?

The detectability of forms embedded within random visual noise has been found to be predictable from the autocorrelation transform of the stimulus pattern (Uttal, 1975). A basic assumption in the autocorrelation theory of form detection is that detectability is determined by the organization of the stimulus pattern, irrespective of the observer’s prior knowledge or expectations about the characteristics of the form. This assumption was tested by determining the effect of the size of the set of alternative target forms on performance of a forced-choice detection task. The targets were composed of dots in a straight line, appearing in one of a specified set of 2, 4, or 8 alternative positions in a pattern of randomly distributed masking dots. Detection accuracy was found to decrease as set size increased, but this decrease was close to what was predicted on the assumption that the random background was independently confusable with the target at each of the alternative positions. Thus, prior knowledge of the set of alternative targets appeared to have no effect on thevisual process, but only on thedecision process by virtue of the features that were relevant criteria for deciding which of the two patterns on each trial was most likely to contain the target. This result is consistent with the autocorrelation theory. This experiment may illustrate how the decision process has influenced the performance in many other experiments that have been assumed to demonstrate an effect of prior knowledge on perception.     

There’s no ball without noise: cats’ prediction of an object from noise

We used an expectancy violation procedure to ask whether cats could use a causal rule to infer the presence of an unseen object on hearing the noise it made inside a container and predict its appearance when the container was turned over. We presented cats with either an object dropping out of an opaque container or no object dropping out (turning-over phase) after producing either a rattling sound by shaking the container with the object inside, or no sound (shaking phase). The cats were then allowed to freely explore the experimental environment (exploration phase). The relation between the sound and the object matched with physical laws in half of the trials (congruent condition) and mismatched in the other half (incongruent condition). Inferring the presence of an unseen object from the noise was predicted to result in longer looking time in the incongruent condition. The prediction was supported by the cats’ behavior during the turning-over phase. The results suggest that cats used a causal-logical understanding of auditory stimuli to predict the appearance of invisible objects. The ecology of cats’ natural hunting style may favor the ability for inference on the basis of sounds.     

‘What’ and ‘where’ in the human visual system: Two hierarchies of visual modules

In this paper we focus on the modularity of visual functions in the human visual cortex, that is, the specific problems that the visual system must solve in order to achieve recognition of objects and visual space. The computational theory of early visual functions is briefly reviewed and is then used as a basis for suggesting computational constraints on the higher-level visual computations. The remainder of the paper presents neurological evidence for the existence of two visual systems in man, one specialized for spatial vision and the other for object vision. We show further clinical evidence for the computational hypothesis that these two systems consist of several visual modules, some of which can be isolated on the basis of specific visual deficits which occur after lesions to selected areas in the visually responsive brain. We will provide examples of visual modules which solve information processing tasks that are mediated by specific anatomic areas. We will show that the clinical data from behavioral studies of monkeys (Ungerleider and Mishkin 1984) supports the distinction between two visual systems in monkeys, the what system, involved in object vision, and the where system, involved in spatial vision.I thank Carole Graybill for editorial help.     

On the Lack of Direction in Rayo’s The Construction of Logical Space

Abstract

I argue that Agustín Rayo’s symmetric ‘just is’ statements cannot be defined in terms of notions like essence, grounding or metaphysical truth-conditions. I go on to argue that one of these latter notions, which allow us to express an asymmetric relationship between facts, is needed to do some of the work that Rayo intends ‘just is’ statements to do, such as stating reductionist claims.     

On the Very Idea of Brandom’s Pragmatism

Although Brandom is critical of some features of narrowly conceived classical pragmatism, at the same time he explicitly embraces a version of pragmatism, both in his overall philosophical outlook, and in his philosophy of language. Brandom’s distinctive theoretical approach is based on what he calls rationalist pragmatism, which is a version of fundamental pragmatism. Within the philosophy of language it takes the form of semantic pragmatism. The paper briefly discusses Brandomian version of fundamental pragmatism and its semantic underpinning, and subsequently formulates a basic dilemma it encounters there.     

Facing the absurd: On Lev Shestov’s angel of death

2018 marks one hundred and fifty two years since the birth of the Russian religious existential thinker Lev Shestov (1866–1938), whose name is counted amongst the most influential European philosophers of the 20^th century. A paradoxical and provocative writer, Lev Shestov searched for ways to diminish the burden of psychological and existential suffering in the life of the individual. His parable about receiving ‘the mysterious gift’ of ‘a new pair of eyes’ from the Angel of Death engaged the existential problems of facing uncertainty, the unknown and death with the possibility of a creative transformation, which could allow an individual to see things outside the law of reason and ‘preconceived self-evident truths.’ Drawing on Shestov’s analysis of Dostoevsky, Nietzsche and Kierkegaard, as well as Camus and Lovtsky’s observations, I argue that Shestov’s interest in the human psyche manifested in his writing, in which he often strove to ‘psychoanalyse’ his characters, found common ground with the psychoanalytical approach. However, unlike Freud’s psychoanalysis, which was grounded in reason and analytical systematisation, Shestov’s philosophy aspired to find a cure to enable an individual to withstand the pressure of the absurd reality of human existence by breaking free from the constraints of rational thought.     

The grammar of aesthetic intuition: on Ernst Cassirer’s concept of symbolic form in the visual arts

This paper provides a précis of Ernst Cassirer’s concept of art as a symbolic form. It does so, though, in a specific respect. It points to the fact that Cassirer’s concept of “symbolic form” is two-sided. On the one hand, the concept captures general cultural phenomena that are not only meaningful but also manifest the way man makes sense of the world; thus myth, religion, and art are considered general symbolic forms. On the other hand, it captures the formal structures and semiotic tools thanks to which meaning is constructed within each general symbolic form (Cassirer called these structures “modes of objectivation”); thus, in art, perspective or the golden section are well-known examples of symbolic forms, now in a narrow sense, i.e. they are means to configure parts into an organized, meaningful whole. The paper will comment on art along both these two dimensions, but its main goal is to provide with concrete examples of aesthetic symbolic forms in the narrow sense in order to show how conceptual meaning can be inscribed in the space of aesthetic intuition.     

On the asymptotic distribution of Pearson’s X 2 in cross-validation samples

In categorical data analysis, two-sample cross-validation is used not only for model selection but also to obtain a realistic impression of the overall predictive effectiveness of the model. The latter is of particular importance in the case of highly parametrized models capable of capturing every idiosyncracy of the calibrating sample. We show that for maximum likelihood estimators or other asymptotically efficient estimators Pearson's X ² is not asymptotically chi-square in the two-sample cross-validation framework due to extra variability induced by using different samples for estimation and goodness-of-fit testing. We propose an alternative test statistic, X _xval ², obtained as a modification of X ² which is asymptotically chi-square with C−1 degrees of freedom in cross-validation samples. Stochastically, X _xval ² ≤ X ². Furthermore, the use of X ² instead of X _xval ² with a χ _C −1² reference distribution may provide an unduly poor impression of fit of the model in the cross-validation sample.

Millennials and the World of Work: An Economist’s Perspective

This article uses an economic approach to address whether and how the Millennial generation is significantly different from its predecessors. Particular attention is paid to the normal life cycle stages through which all generations pass, and the implications for forecasting how the Millennials’ relationship with the world of work will evolve. A second key issue is the extremely large differences in economic opportunity that exist among the members of each generation, and which have increased for more recent generations, particularly those with lower levels of education. Other key issues include the rise in international competition for jobs, and the rising cost of a college education. These factors together imply that simple stereotypes about Millennials taking a privileged view of the world of work may be simplistic at best, and likely are significantly off target.
