The influence of the number of toys in the environment on toddlers’ play

We tested the hypothesis that an environment with fewer toys will lead to higher quality of play for toddlers. Each participant (n = 36) engaged in supervised, individual free play sessions under two conditions: Four Toy and Sixteen Toy. With fewer toys, participants had fewer incidences of toy play, longer durations of toy play, and played with toys in a greater variety of ways (Z = −4.448, p < 0.001, r = −0.524; Z = 2.828, p = 0.005, r = 0.333; and Z = 4.676, p < 0.001, r = 0.55, respectively). This suggests that when provided with fewer toys in the environment, toddlers engage in longer periods of play with a single toy, allowing better focus to explore and play more creatively. This can be offered as a recommendation in many natural environments to support children’s development and promote healthy play.     

Combined visual illusion effects on the perceived index of difficulty and movement outcomes in discrete and continuous fitts’ tapping

The speed-accuracy trade-off is a fundamental movement problem that has been extensively investigated. It has been established that the speed at which one can move to tap targets depends on how large the targets are and how far they are apart. These spatial properties of the targets can be quantified by the index of difficulty (ID). Two visual illusions are known to affect the perception of target size and movement amplitude: the Ebbinghaus illusion and Muller-Lyer illusion. We created visual images that combined these two visual illusions to manipulate the perceived ID, and then examined people’s visual perception of the targets in illusory context as well as their performance in tapping those targets in both discrete and continuous manners. The findings revealed that the combined visual illusions affected the perceived ID similarly in both discrete and continuous judgment conditions. However, the movement outcomes were affected by the combined visual illusions according to the tapping mode. In discrete tapping, the combined visual illusions affected both movement accuracy and movement amplitude such that the effective ID resembled the perceived ID. In continuous tapping, none of the movement outcomes were affected by the combined visual illusions. Participants tapped the targets with higher speed and accuracy in all visual conditions. Based on these findings, we concluded that distinct visual-motor control mechanisms were responsible for execution of discrete and continuous Fitts’ tapping. Although discrete tapping relies on allocentric information (object-centered) to plan for action, continuous tapping relies on egocentric information (self-centered) to control for action. The planning-control model for rapid aiming movements is supported.     

Seeing or smelling? Assessing personality on the basis of different stimuli

This study examines whether people can accurately assess personality on the basis of facial images and body odor and whether attractiveness influences these relationships. Three personality dimensions of target individuals – neuroticism, extraversion and dominance – were measured with the NEO Five-Factor Inventory, a one-item measure of dominance and the reports of close acquaintances. Naive observers assessed neuroticism and dominance at above-chance levels based on body odor, and they assessed extraversion (and in some cases, neuroticism) at above-chance levels based on either facial images alone or body odor and facial images presented together. The accuracy differed depending on the sex of the targets and the raters. In addition, facial and body odor attractiveness predicted the targets’ personalities and the assessments of their personalities. These results show that the accuracy of personality assessment changes when judges assess different types of stimuli.     

Al-Ghazali’s Position on the ‘Second Proof’ of the ‘Philosophers’ for the Eternity of the World,in the First Discussion of the Incoherence of the Philosophers

In the Incoherence of the Philosophers, Abu Hamid al-Ghazali (1058-1111) raised objections against the doctrine of the ‘philosophers’ (represented chiefly by al-Farabi and Ibn Sina) on 20 specific points. In the first, and longest discussion, he examines and rebuts four of their proofs of the pre-eternity of the world—that is, that the universe as a whole had no beginning but extends perpetually into the past. Al-Ghazali rejects that doctrine. But his own position on the issue does not become clear until he discusses the philosophers’ ‘second proof.’ In this paper, I will examine the relevant text of the Incoherence of the Philosophers, in order to clarify the nature of Al-Ghazali’s position in relation to the second proof. I will explain why Al-Ghazali cannot adopt what I refer to as the ‘naïve’ theological position, according to which God temporally preceded the world. Instead, Al-Ghazali concurs with the philosophers that time is the measure of motion, but he asserts that time was created with the world, both having a beginning before which there was no time. God, on the other hand, is not temporally prior to the world, but neither is he simultaneous, as the second proof supposes. As timelessly eternal, God bears no temporal relation to the world at all. In conclusion, I describe what I refer to as a naïve philosophical position, which is entailed by the second proof, but distinct from both Al-Ghazali’s position and that adopted by Ibn Rushd in his critique of Al-Ghazali in the Incoherence of the Incoherence. I argue that this naïve philosophical position (and thus, the second proof) is incoherent.     

Influence of auditory and audiovisual stimuli on the right–left prevalence effect

When auditory stimuli are used in two-dimensional spatial compatibility tasks, where the stimulus and response configurations vary along the horizontal and vertical dimensions simultaneously, a right–left prevalence effect occurs in which horizontal compatibility dominates over vertical compatibility. The right–left prevalence effects obtained with auditory stimuli are typically larger than that obtained with visual stimuli even though less attention should be demanded from the horizontal dimension in auditory processing. In the present study, we examined whether auditory or visual dominance occurs when the two-dimensional stimuli are audiovisual, as well as whether there will be cross-modal facilitation of response selection for the horizontal and vertical dimensions. We also examined whether there is an additional benefit of adding a pitch dimension to the auditory stimulus to facilitate vertical coding through use of the spatial-musical association of response codes (SMARC) effect, where pitch is coded in terms of height in space. In Experiment 1, we found a larger right–left prevalence effect for unimodal auditory than visual stimuli. Neutral, non-pitch coded, audiovisual stimuli did not result in cross-modal facilitation, but did show evidence of visual dominance. The right–left prevalence effect was eliminated in the presence of SMARC audiovisual stimuli, but the effect influenced horizontal rather than vertical coding. Experiment 2 showed that the influence of the pitch dimension was not in terms of influencing response selection on a trial-to-trial basis, but in terms of altering the salience of the task environment. Taken together, these findings indicate that in the absence of salient vertical cues, auditory and audiovisual stimuli tend to be coded along the horizontal dimension and vision tends to dominate audition in this two-dimensional spatial stimulus–response task.     

Does the use of natural stimuli facilitate amodal completion in pigeons?

Three experiments were carried out to investigate whether amodal completion in pigeons can be facilitated by the use of colour photographs instead of highly artificial stimuli such as geometrical shapes. Ten pigeons were trained in a go/no-go procedure to discriminate between photographs of complete and of incomplete pigeon figures. In the subsequent test, the birds classified pictures of partly occluded pigeons as though they were complete (experiment 1). However, we found evidence that classification was based on spurious stimulus features that paralleled the intended class rule of figural completeness versus incompleteness. In particular, classification was shown to be guided by white background gaps that separated the parts of the fragmented pigeon figures (experiment 2), as well as by cues related to overall Gestalt (experiment 3). In summary, the present results indicate that the use of more natural stimuli such as photographs instead of geometrical shapes is insufficient for providing amodal completion in pigeons. It is suggested that a combination of various cues, including, eg, 3-D information and common motion in addition to surface and contour properties, may be required to induce a perceptual bias favouring visual completion of occluded portions.     

Influence of following vehicle’s tailway and classification on subject driver’s response to the circular yellow indication

Traffic crashes at signalized intersections are frequently linked to driver behavior at the onset of the circular yellow (CY) indication. To better understand behavioral factors that influence a driver’s decision to stop or go at an intersection, this study analyzed the behavior of the driver of a subject vehicle at the onset of the CY indication. Driver performance data from 53 participants were collected in the Oregon State University Driving Simulator, simulating scenarios of driving through high-speed intersections under various conditions. Data included interactions where the driver stopped at the stop line (n = 644) or proceeded through the intersection (n = 628) in response to a CY indication. Data were analyzed as panel data while considering 12 indicator variables related to the driver’s stop/go decision. These indicator variables included time to stop line (TTSL), tailway time, following vehicle type, vehicle speed at the onset of the CY indication, and demographics (age, gender, driving experience, level of education, personal vehicle type, number of times driving per week, number of miles driving last year, participation in previous simulation studies. A random-parameter binary logit model was used to determine contributing factors for driver decision making at the onset of CY indication while accounting for unobserved heterogeneity. Four indicator variables were significantly related to the driver’s stop/go decision, but three factors varied across observations. Findings showed that a driver’s stop/go decision in response to a CY indication was associated with the time to the stop line (TTSL), tailway time to the following vehicle, subject vehicle speed at the onset of the CY indication, and driver’s age (20–36 years), but was not significantly associated with classification of the following vehicle. Also, the findings indicated that a shorter tailway increased a subject driver’s red-light running frequency. These findings provide insights into variables that affect driver decisions in a vehicle-following situation at the onset of the CY indication. This information can help make better decisions in smart traffic control systems such as to extend/decrease the green interval slightly to avoid decisions that are more difficult.     

Are conditioned stimuli determinants of oriented exploratory behavior in the rat?

To test Bindra and Palfai's hypothesis about enhancing and inhibitory motivational effects of a conditioned stimulus on exploratory behavior, rats in a first experiment were submitted to pairings of a tone with (a) water, (b) intermittent deliveries of water after a period of constant pairing. In a control condition, the tone was presented alone. The tone was subsequently presented during oriented exploration of a novel stimulus, in the conditioning context. There was no difference in exploratory performance between conditions. In a second experiment with another kind of stimulus change and a larger number of training trials, exploration did not increase when occurring during CS presentation. The lack of facilitation which is possibly the product of competition between exploration and magazine-directed responses, can also be interpreted as indicating that the effects of a conditioned stimulus are reinforcer specific and that the diffuse activity it generates in a situation different from the training one is not equivalent, as concerns the processes involved, to oriented exploratory behavior.     

The form of the soul ― on the body in Freud’s psychoanalysis

To formulate the problem of the relation between body and soul in terms of how one should understand the relation between consciousness and the brain, or in terms of explaining how mind can arise out of matter, is a modern and far from innocent tendency that has instigated the whole spectrum of theories and answers suggested by the philosophy of mind of the so-called Analytic tradition during the 20th century. During the last 5 decades, we have seen a number of attempts at incorporating Freud into this discussion about the relation between body and soul. In this article, the author develops an argument according to which the philosophy of mind of the Analytic tradition is not really an appropriate intellectual environment for Freud´s theory of the body and its constitutive rôle. Rather, we should turn to phenomenology and transcendental philosophy where the body is thematized, not in terms of matter taken to give rise to consciousness in an empirical sense, but rather in terms of the “lived body” that is taken, in a transcendental sense, to constitute the organization of meaning in our conscious and our unconscious psychological life. On the basis of an outline of this phenomenological theory, the author argues that Freud, most of all in his theory of psychosexual development, thematizes the body as the form of the soul.

Al-Ghazali’s Reflections on the Metaphysics of Metaphor in the Mishkāt al-Anwar

Mythological language is sometimes understood as a way of representing, by concrete imagery, more abstract notions. In this paper, we will pose some metaphysical questions about the possibility of such a representation. These questions will serve to motivate a brief tour of Mishkāt al-Anwār (Niche of Lights)—Abu Hamid al-Ghazali’s commentary on the famous ayat al-nur (“verse of light”) of the Qur’an—wherein is discussed, among other things, how symbolic imagery is possible, and “the respect in which the spirits of the meanings are specified within the frames of the similitudes.”

The Influence of Heidegger’s Thought on the Development of Philosophy in Ex-Yugoslav Countries

The purpose of the article is to present the outlines of the reception and the influence of Heidegger’s philosophy on the territory of former Yugoslavia. This reception and influence were in their essence co-conditioned by specific political, social and cultural circumstances in the region, which were throughout accompanied by “the syndrome of dehumanization”. The confrontation with Heidegger’s philosophy is therefore co-defined by the profoundly experienced crisis of European humanity. During both world wars the attempt of an overcoming of this crisis of humanity by the means of phenomenological and existentialist philosophy was the main focus of attention. The period after the Second World War is denoted by the linking of Marxism with Heidegger’s attempt to surpass philosophy as metaphysics through the perspective of the history of being; in this context we specifically discuss the Praxis philosophical school and the original philosophical thought of Vanja Sutli?. During the disintegration of Yugoslavia and in the period thereafter, besides the intensive appropriation of Heidegger’s thought through translations and interpretations, which also led to the thorough study of Slavic philosophical terminologies, post-Heideggerian ways of thinking came to the fore, together with the possibility for a new humanization within the wider European and global social framework.     

The Impact of Decision Timing on the Effectiveness of Leaders’ Apologies to Repair Followers’ Trust in the Aftermath of Leader Failure

Purpose

The aim of the present research was to investigate how a negative decision outcome generated by a leader in a hasty, timely, or delayed manner impacts upon the need for, and the effectiveness of apologies to restore followers’ trust.

Design/Methodology/Approach

Data were collected using five studies in which the effects of timing of an incorrect decision on the trust repair process were investigated.

Findings

In the aftermath of a leader’s failure, followers experienced a delayed incorrect decision as a more severe transgression than a hasty or a timely incorrect decision. This effect was mediated by procedural fairness concerns (Study 1). The present findings also revealed an interesting paradox. Specifically, in the delayed condition followers expressed the highest need for an apology (Studies 2 and 3), but at the same time expected an apology to be less effective for enhancing trustworthiness than in the timely and the hasty condition (Study 3). Moreover, we also showed that the actual provision of an apology was effective for restoring both trustworthiness (Study 4) and trust (Studies 4 and 5) in the timely and the hasty condition, but ineffective in the delayed condition.

Implications

The present research shows that when the outcome of a decision is uncertain, it is better to make a decision (too) soon rather than (too) late.

Originality/Value

Despite the ubiquity of timing errors in daily life, our studies are the first to focus on the role of timeliness of decisions in the trust repair process.

Exploring the effects of EEG signals on collision cases happening in the process of young drivers’ braking

Detecting mental states in drivers offers an opportunity to reduce accidents by triggering alerts and signaling the need for rest or renewed focus. Here we used electroencephalography (EEG) to measure brain signals in young drivers operating a driving simulator to detect mental states and predict accidents. We measured reaction times to unexpected hazardous events and correlated them with EEG signals measured from the frontal, parietal, and temporal cortices as well as the central sulcus (corresponding to motor cortex). We found that EEG signals in the relative beta (power in beta (13–30 Hz) relative to total power of the EEG (0.5–30 Hz)), alpha/delta, alpha/theta, beta/delta, beta/theta frequency bands were higher for collisions than successful collision avoidance, and that the key decision-making period is the 2nd second before braking. Importantly, a decision tree classifier trained on these neural signals predicted collision avoidance outcomes. Then based on random forest model, we extracted three critical neural signals (beta/delta_frontal, relative beta_parietal and relative beta_central Sulcus) to classify collision avoidance outcomes. Our findings suggest measuring EEG during driving may provide useful signals for enhancing driver safety.
