Cyclist strategies and behaviour at intersections. Conscious and un-conscious strategies regarding positioning

Severe and even fatal accidents between cyclists and motor vehicles commonly occur at intersections. Many of these accidents occur with right-turning vehicles, with drivers not observing an adjacent cyclist. Few structured investigations exist regarding the interaction between cyclist and motor vehicle, and factors in need of study are how infrastructure and vehicle properties affect human decision-making and cycling behaviour. Therefore, a bicycle simulator study was performed, where vehicle type, presence of lane markings and lane width were systematically varied in a scenario with a cyclist approaching a vehicle from behind, at a signalized city intersection. 33 participants cycled through 8 intersection variants each. Data on cycling trajectories, stopping points and speed was coupled with survey data from the participants, and semantically categorized verbal responses to questions regarding strategy for choice of stopping point. Results show that all three factors (vehicle type, lane markings and available vehicle-adjacent space) significantly affects cyclists’ behaviour and conscious strategies. Participants were more cautious in the presence of a truck than a car, reflected in choice of position when cycling and stopping, and in explicit verbalisations regarding perilous aspects of the situation and their conscious and strategic choice of positioning. Available lateral space also affected stop positions and feeling of safety (expressed verbally). Presence of bicycle lane markings made the cyclists inclined to continue into the space to the right of the vehicle. This was revealed by their positioning and speed, and also apparent in the verbal expressions, especially the positive remarks on the situation and conditions. However, the perceived comfort with lane markings present was actually lower than when they were missing. Cyclist type (slow, moderate, or fast) matters with the self-reported faster cyclists being more prone to stop to the right than the slower one.     

An Exploration of Johnson's Sense of ‘Argument’

This essay attempts to give definitions and identity conditions for the two predominant senses of Argument currently in use, the one involving reasons for a conclusion and the other denoting an expressed disagreement with ensuing verbal behaviour by two parties. I see Johnson's new concept of Argument, as developed in his book Manifest Rationality, as a hybrid of the two common senses of Argument, and, accordingly, I try to define and give the identity conditions of Johnson-arguments. Finally, I disagree with Johnson on the nature of the definition he thinks he has proposed, and I conclude with observations suggesting that his logical perspective has dialectical and rhetorical components.     

Identity, narcissism and the emotional core

This paper describes the course of an analysis which demonstrates how borderline and narcissistic functioning can be understood in terms of a struggle with issues of identity. It shows how such functioning can come to exert a profound hold on the individual and why it seems, at times, a matter of life and death to the patient to avoid states of separation from the analyst. The paper suggests that these complex phenomena can be understood, perhaps surprisingly, in the simple terms of the nature of affect itself. The concept of the emotional core is introduced to embody and highlight that which lies beneath both Jungian and Freudian models (offering a potential bridge between the two models)--namely the psyche's essentially affective nature. It is suggested that the emotional core can serve as an organ of perception giving the individual both their primary relation to reality and an emotional attachment to others. This emotional core is understood to function in a narcissistic manner to preference experiences of sameness and in aversion to experiences of difference--a view consonant with Stern's understanding of infant development where the infant is able to distinguish self from other from the beginning of life (as Fordham also held); taking up Stern's terminology, it gives the individual a 'core' sense of being. There is, however, no stable, on-going sense of 'I' associated with this form of functioning as the individual is immersed in the latest affect to enter consciousness (as in the borderline state of mind) and consequently the individual comes to rely intensely on the other to determine their sense of being (the other becomes a self-regulating other in Stern's terms). The development of ego-functioning gives a more stable and on-going sense of 'I' to the individual, giving contact with the broader personality, allowing the individual to be less reliant on the other and orientating them to reality in a way more fitting to their overall needs. The paper describes how consciousness, which is not seen as identical with the ego, moves between the mode of functioning of the ego and that of the emotional core, i.e., shifting in and out of states where projective identification predominates. It elaborates the range of self-experience encompassing spiritual experience and states of disintegration (which are understood to have a similar structure) on one side, to ego-based experience (which can itself be defensive and rigid at times) on the other. It explores the consequences of such a view for analytic technique and relates it to the Jungian view of the self and the Freudian unconscious.

Why Don't People Change? What Stops Them from Changing? An Integrative Commentary on the Special Issue on Resistance

This commentary discusses the four papers from the vantage point of a cognitive-developmental view. Psychotherapeutic change involving changes in core cognitive structures is seen as threatening an individual's personal sense of identity as well as security and safety needs. Core cognitive constructs are laid down early via the principle of covariation of events and form the basis of our tacit knowledge base. Subsequent changes in this tacit knowledge is difficult because the core cognitive constructs act like a mental filter to screen in confirming data and screen out disconfirming data. Ambiguous stimuli tend to be interpreted on the basis of preexisting cognitive constructs, even when the match between event and interpretation is not ideal. Several suggestions are given for increasing the probability of changes occurring in core cognitive constructs.     

A calibration explanation of serial position effects in evaluative judgments

Judges often evaluate stimulus series on dimensions for which no physical scale exists; for example, when judging academic ability in oral examinations. We propose that judges deal with this problem by calibrating an internal judgment scale that maps stimulus input onto available judgment categories. This calibration process implies serial position effects: Judges should initially avoid extreme categories, because using extreme categories reduces judgmental degrees of freedom, thereby increasing the possibility of internal consistency violations. In four experiments, we show that judgments become indeed more extreme later in a series of judgments. Judges evaluated the same good (poor) performances more positive (negative) at the end of a sequence compared to the beginning. Judges’ expertise did not prevent the effect, but allowing end-of-sequence judgments reduced serial position effects. We discuss the implications and possible remedies of these calibration effects on judgment extremity.

Is It Lonely at the Top? An Empirical Study of Managers’ and Nonmanagers’ Loneliness in Organizations

Loneliness is often assumed to be an occupational hazard for senior-ranked members of an organization. However, most of what researchers hear about being "lonely at the top" is anecdote. This article provides empirical evidence from three separate studies assessing loneliness in managers and nonmanagers. Across all three studies, loneliness did not differ by managerial status. Managers were no more or less lonely than their nonmanager counterparts. This suggests that factors beyond seniority may be contributing to loneliness in organizational settings. Ideas for future research are discussed.     

Exploring the enactment effect from an information processing view: What can we learn from serial position analyses?

The focus of the present article was to analyze processes that determine the enactment and age effect in a multi-trial free recall paradigm by looking at the serial position effects. In an experimental study (see Schatz et al 2010), the performance-enhancing effect of enactive encoding and repeated learning was tested with older and younger participants. As expected, there was a steady improvement of memory performance as a function of repeated learning regardless of age. In addition, enactive encoding led to a better memory performance than verbal encoding in both age groups. Furthermore, younger adults outperformed the elderly regardless of type of encoding. Analyses in the present article show that encoding by enacting seems to profit especially from remembering the last items of a presented list. Regarding age differences, younger outperformed older participants in nearly all item positions. The performance enhancement after task repetition is due to a higher amount of recalled items in the middle positions in a subject performed task (SPT) and a verbal task (VT) as well as the last positions of a learned list in VT.
