ERRATA

As mentioned in the editorial, we publish here five papers introducing the small group discussions. The authors of these papers and the editorial board wish to emphasize that these papers were not presented with a view to publication, and thus they do not pretend to be independent and original contributions.

However, the editorial board regarded these papers as valuable in various ways, and they are also illustrative of some of the variations of the theme of the congress. The papers are published here in only a slightly revised form.     

Gradual remapping results in early retinotopic and late spatiotopic inhibition of return

Here we report that immediately following the execution of an eye movement, oculomotor inhibition of return resides in retinotopic (eye-centered) coordinates. At longer postsaccadic intervals, inhibition resides in spatiotopic (world-centered) coordinates. These results are explained in terms of perisaccadic remapping. In the interval surrounding an eye movement, information is remapped within retinotopic maps to compensate for the retinal displacement. Because remapping is not an instantaneous process, a fast, but gradual, transfer of inhibition of return from retinotopic to spatiotopic coordinates can be observed in the postsaccadic interval. The observation that visual stability is preserved in inhibition of return is consistent with its function as a "foraging facilitator," which requires locations to be inhibited across multiple eye movements. The current results support the idea that the visual system is retinotopically organized and that the appearance of a spatiotopic organization is due to remapping of visual information to compensate for eye movements.     

A Direct Observation of the Dynamic Content and Structure of Coach-Athlete Interactions in a Model Sport Program

The purpose of this study was to analyze the coach-athlete interactions in a successful sport program for athletes with disabilities and their able-bodied siblings. The coach and 24 athletes were observed over multiple practice sessions. Measures of interaction content and structure were derived using state space grid (SSG) analysis. Results indicated that interactions were patterned and included behaviors such as individualized instruction, organization, and feedback. Interaction style changed according to the athletes’ competitive level, but no differences emerged based on disability status. This successful sport environment was characterized by patterned and positive coach-athlete interactions that were athlete, rather than disability-focused.     

How reaction time measures elucidate the matching bias and the way negations are processed

Matching bias refers to the non-normative performance that occurs when elements mentioned in a rule do not correspond with those in a test item (e.g., consider the double mismatch between the rule If there is a not a T on the card then there is not a 4 and a card showing H6). One aim of the present work is to capture matching bias via reaction times as participants carry out truth-table evaluation tasks. Experiment 1 requires participants to verify conditional rules, and Experiment 2 to falsify them as the paradigm (a) employs four types of conditional sentences that systematically rotate negatives in the antecedent and consequent; and (b) presents predominantly cases having true antecedents. These experiments reveal that mismatching is linked to higher rates of incorrect responses and slower evaluation times. A second aim is to investigate the way not is processed. We compare a narrow view of negations, which argues that negation only denies information (e.g., not-T only says there is no T), to a search for alternatives view, which says that negations function to prime appropriate alternatives (e.g., not-T primes a search for other letters). Findings from both experiments support a narrow reading view.     

Social Participation During Transition to Adult Life Among Young Adults With High-Functioning Autism Spectrum Disorders: Experiences From an Exploratory Multiple Case Study

This study aimed to explore the social participation of young adults with high-functioning autism spectrum disorders (HFASD) during their transition to adult life. A multiple case study was conducted using semi-structured interviews with a purposive sample of 10 participants (n = 10) composed of three adults with HFASD, their caregivers, and two representatives of community organizations. Four themes emerged: (1) access to services, (2) orientation to integrated life goals, (3) engagement in meaningful activities, and (4) gap in services before reaching independent living. Properly preparing and orienting the families could help them have a more satisfying social participation.     

Affective stimulus properties influence size perception and the Ebbinghaus illusion

In the New Look literature of the 1950s, it has been suggested that size judgments are dependent on the affective content of stimuli. This suggestion, however, has been 'discredited' due to contradictory findings and methodological problems. In the present study, we revisited this forgotten issue in two experiments. The first experiment investigated the influence of affective content on size perception by examining judgments of the size of target circles with and without affectively loaded (i.e., positive, neutral, and negative) pictures. Circles with a picture were estimated to be smaller than circles without a picture, and circles with a negative picture were estimated to be larger than circles with a positive or a neutral picture confirming the suggestion from the 1950s that size perception is influenced by affective content, an effect notably confined to negatively loaded stimuli. In a second experiment, we examined whether affective content influenced the Ebbinghaus illusion. Participants judged the size of a target circle whereby target and flanker circles differed in affective loading. The results replicated the first experiment. Additionally, the Ebbinghaus illusion was shown to be weakest for a negatively loaded target with positively loaded and blank flankers. A plausible explanation for both sets of experimental findings is that negatively loaded stimuli are more attention demanding than positively loaded or neutral stimuli.     

Reading the Lucan call of the first disciples differently: the voices of sensing and intuition

Abstract

This article argues that discipleship is a notion of growing importance to the Christian denominations and that the Marcan narrative of the call of the first disciples has been of particular importance in giving shape to this notion. The Lucan narrative of the call of the first disciple, involving the great catch of fish, is problematic in two ways, concerning its relationship with the Marcan understanding of call and also with the Johannine post-resurrection narrative. Against this background this article reports on an empirical study, drawing on the reader perspective and on the SIFT approach to biblical hermeneutics, that illuminates the distinctive voices of sensing types and intuitive types reading Luke 5: 1–7.     

Subjective time: cognitive and physical secondary tasks affect timing differently

Humans were trained on a temporal discrimination to make one response when the stimulus duration was short (2 s) and a different response when the stimulus duration was long (8 s). They were then tested with stimulus durations in between to determine the bisection point. In Experiment 1, we examined the effect of a secondary cognitive task (counting backwards by threes) on the bisection point when participants were trained without a cognitive load and were tested with a cognitive load or the reverse (relative to appropriate controls). When the cognitive load increased from training, the psychophysical function plotting long responses against the increase in stimulus duration shifted to the right (as if the internal clock slowed down), and when the cognitive load decreased from training the psychophysical function shifted to the left (as if the internal clock speeded up). In Experiment 2, when the secondary task consisted of exerting continuous force on a transducer (a physically effortful task), it had the opposite effect. When the required force increased from training, the psychophysical function shifted to the left (as if the internal clock speeded up), and when the required force decreased from training, the psychophysical function shifted to the right (as if the internal clock slowed down). The results support an attentional view of the subjective passage of time. A cognitive secondary task appears to decrease attention to temporal cues, resulting in the underestimation of the passage of time, whereas a force requirement appears to increase attention to temporal cues, resulting in the overestimation of the passage of time.
