Predictive Pointing Movements and Saccades Toward a Moving Target

The authors investigated whether and, if so, how velocity information is used to control predictive manual pointing movements and saccades. Participants (N = 6) intercepted an occluded moving target as if it were still visible. They kept their eyes fixated while the target moved. The target traveled over a fixed distance and changed its velocity on the way. The presentation time of the final velocity was varied. Both the eye and the hand overshot the slow target and undershot the fast target, particularly when the duration of the final velocity was short. Thus, responses were biased in the direction of the target's initial velocity. The error seemed to arise because participants did not take their latency into account when aiming at the target. Instead, they strategically aimed farther ahead when the target was fast. Amplitude was also more related to the position of velocity change than to final velocity duration. Both findings suggest that target velocity is not extrapolated but that individuals add an increment to the position of velocity change.     

Wittgenstein on Expectation,Action, and Internal Relations, 1930–1932

According to Wittgenstein, internal relations are such that, once their terms are given, it is unthinkable that they do not hold. In his early philosophy, the concept of internal relation plays a central role in his views on meaning. The present paper addresses the question of how Wittgenstein's views about internal relations develop during his years of transition (1930–32). In particular, it investigates the connections between the concepts of internal relation, logical multiplicity, and aspect seeing in two thematic fields: (1) Wittgenstein's discussion of the relation between an expectation and what fulfils it, and (2) his discussion of the relation between a sign and an action guided by it.     

Differentiating sexual preference in men: Using dual task rapid serial visual presentation task

Cognition research suggests that allocating attention resources to evolutionarily relevant stimuli is facilitated suggesting that sexual stimuli interfere with human information processing. In a group of gay (n = 13) and straight men (n = 13) recruited in Finland, Germany and Italy, we investigated if and how sexually relevant visual stimuli affect information processing of both a target one (T1) and a subsequent target two (T2) in a dual target rapid serial visual presentation procedure. We hypothesized that: (1) due to the attentional blink (AB) phenomenon, the accuracy of reporting of T2 would decrease when following accurately identified sexually preferred T1 compared to accurately identified non‐sexually preferred T1; 2) due to the pop out effect, the accuracy of reporting of T1 and T2 would be relatively increased when T1 and T2 were sexually preferred by the participants compared to when they were not. Our findings did not support hypothesis 1 but supported hypothesis 2. We further found that the pop out effect had a good capacity to differentiate sexual preference between the groups of gay and straight men. We conclude that dual target rapid serial visual presentation can be used as an attention‐based measurement to differentiate sexual preference in men. Limitations and the applicability in the field of measuring sexual preference were discussed.     

Why metrical properties are not powers

What has the dispositional analysis of properties and laws (e.g. Molnar, Powers, Oxford University Press, Oxford, 2003; Mumford, Laws in nature, Routledge London, 2004; Bird, Nature’s metaphysics, Clarendon Press, Oxford, 2007) to offer to the scientific understanding of physical properties?—The article provides an answer to this question for the case of spacetime points and their metrical properties in General Relativity. The analysis shows that metrical properties are not ‘powers’, i.e. they cannot be understood as producing the effects of spacetime on matter with metaphysical necessity. Instead they possess categorical characteristics which, in connection with specific laws, explain those effects. Thus, the properties of spacetime do not favor the metaphysics of powers with respect to properties and laws.     

Emotional expression affects the accuracy of gaze perception

Emotional facial expressions are powerful social cues. Here we investigated how emotional expression affects the interpretation of eye gaze direction. Fifty-two observers judged where faces were looking by moving a slider on a measuring bar to the respective position. The faces displayed either an angry, happy, fearful or a neutral expression and were looking either straight at the observer, or were rotated 2°, 4°, 6° or 8° to the left and right. We found that happy faces were interpreted as directed closer to the observer, while fearful and angry faces were interpreted as directed further away. Judgments were most accurate for neutral faces, followed by happy, angry and fearful faces. These findings are discussed on the background of the “self-referential positivity bias”, suggesting that happy faces are preferably interpreted as directed towards the self while negative emotions are interpreted as directed further away.     

Developmental intelligence: From empirical to hidden constructs

This article answers some of the criticisms and suggestions of the three commentaries. We showed, in agreement with Coyle, that (i) variability is indeed distinct from speed, (ii) they both additively reflect processing efficiency and (iii) that they differentially relate to WM and gf during development. In agreement with Kail, we showed that developmental intelligence and psychometric intelligence are (i) related but distinct, they additively contribute to school learning and (iii) their role varies with developmental phase. Finally, in agreement with Pascual-Leone, we proposed a number of higher level hidden constructs to account for the data patterns observed between empirical constructs, such as speed, variability, WM, and reasoning.     

“When I Was Young” The Idealization of the Interchangeability of Phases of Life

This paper presents the concept of the idealization of the interchangeability of phases of life as an enhancement, or rather as a further development of Alfred Schutz’s general thesis of the reciprocity of perspectives. It claims that the according figure of thought is a constitutive part of acts of understanding in everyday life where, in order to understand each other, individuals of different age-groups have to overcome the difference of perspectives that are attached to their particular ages. This is accomplished by a specific assumption that is also applied in the case of intrasubjective, autobiographical understanding. By discussing its sociological significance as well as its philosophical background, this paper introduces the idealization of the interchangeability of phases of life as a fundamental and universal figure of understanding.     

Effects of the Early Prevention Program “Keiner FÄllt Durchs Netz” (“Nobody Slips Through the Net”) on Child,Mother, and Their Relationship: A Controlled Study

The study investigated the effects of a German family‐supporting prevention program “Keiner fällt durchs Netz” (KfdN; “Nobody Slips Through the Net”) after the child's first year in the sample of 152 psychosocially stressed mothers and children who took part in this program and 150 mothers and children from comparison‐group families. The improved level of development posited in the children after intervention as compared to children from the comparison group was confirmed in the social development area (d = .35). In addition, mothers in the KfdN group judged their 1‐year‐old children to be less “difficult” compared to the assessments of the mothers in the comparison group (d = .24). Due to the intervention, the dysfunctionality of the mother–child interaction was reduced (mothers’ self‐assessment, d = .27). No intervention effects were found in for degree of maternal stress. The expected intervention effects in maternal sensitivity were not empirically confirmed. The results suggest that the KfdN intervention exerted a direct positive influence on childhood traits such as social development and temperamental “difficulty” and also positively influenced the mothers’ perceptions or attitudes toward their children's conduct.     

Critical Realism—A Sustainable Bridge Between Science and Religion?

Since Barbour's introduction of the term in 1966, “critical realism” bridges the gulf between science and religion. Yet, like the Golden Gate Bridge, this bridge must be supported by pillars to carry its weight. These pillars are the social and the human sciences, which are still designed too small within critical realism to make a really sustainable construct. Critical realism should be modified to “constructive-critical realism” to allow for more weight of these disciplines in the dialog, which actually should become a trialog.     

Blameworthiness as Deserved Guilt

It is often assumed that we are only blameworthy for that over which we have control. In recent years, however, several philosophers have argued that we can be blameworthy for occurrences that appear to be outside our control, such as attitudes, beliefs and omissions. This has prompted the question of why control should be a condition on blameworthiness. This paper aims at defending the control condition by developing a new conception of blameworthiness: To be blameworthy, I argue, is most fundamentally to deserve to feel guilty. Being blamed by someone else is not necessarily harmful to the wrongdoer. The blame might not be expressed, or the wrongdoer might not care. But to blame oneself necessarily involves suffering. This conception of blameworthiness explains why the control condition should obtain: We are morally blameworthy for A only if A was (directly or indirectly) under our control because (a) to be blameworthy is to deserve to feel guilty, (b) to feel guilty is to suffer, and (c) one deserves to suffer for A only if A was under one’s control.
