The role of Funktionswandel in metamorphopsia

Patients with metamorphopsia perceive objects or faces as being distorted and/or different in size. In most cases, recognition is not impaired. The stimulus specificity, particularly in the case of face perception, has led to the suggestion that metamorphopsia is a deficit at the entry level of category‐specific recognition systems; in this case, the face processing system. An explanation in terms of a visuosensory deficit (i.e. Funktionswandel) that affects the perception of specific stimulus categories has not been systematically evaluated. In this study, we report two patients (MZ and CM) who experienced hemi‐metamorphopsia for faces after a stroke in the posterior part of the brain. Despite the distortions, they could still match and recognize faces. We carried out a detailed evaluation of their visual‐sensory status and found that both MZ and CM had specific problems with discriminating and estimating sizes and shapes, especially in the contralesional visual field. It was concluded that these cases, metamorphopsia was not due to a higher‐order perception impairment specific for faces, but rather of a specific impairment in shape perception in the contralesional visual field that proportionally affects the perception of faces.     

Reconsidering the relationship between parenting and religiosity

This study examined the relation between religiosity and parenting. 311 parents from the Flemish-speaking part of Belgium completed the Post-critical Belief Scale and reported on their style of parenting. Scores for religiosity (as measured by the Exclusion vs Inclusion of Transcendence dimension) were not significantly correlated with parenting styles. In contrast, the way in which religious contents are processed (as measured by the Literal vs Symbolic dimension) was significantly correlated with dimensions of parenting style.     

Gait adjustments in response to an obstacle are faster than voluntary reactions

It has been reported that obstacle avoidance reactions during gait have very short latencies. This raises the question whether the cortex can be involved, as it is in voluntary reactions. In this study, latencies of obstacle avoidance (OA) reactions were determined and related to latencies of voluntary stride modifications and simple reaction times (SRT) of hand and foot. Twenty-five healthy young adults participated in this study. While they were walking on the treadmill, an obstacle suddenly fell in front of their left leg. The first reaction to the obstacle was the moment at which the differentiated acceleration curve of the foot deviated from the control signal. Latencies of OA reactions were 122 ms (SD 14 ms) on average. Two very different avoidance reactions (lengthening and shortening of the stride) were noticed, but there was no avoidance strategy effect on OA latencies. OA latencies were significantly shorter as compared to latencies of voluntary stride modifications and simple reaction times of hand and foot. The short OA latencies could not only be explained from the dynamic nature of the task. It is suggested that subcortical pathways might be involved in obstacle avoidance.     

Evil intent and design responsibility

Mass casualty attacks in recent years have demonstrated the need to include “evil intent” as a design consideration. Three recent actual or potential weapons of mass destruction (WMD) attacks did not involve nuclear bombs or other devices designed as weapons, but rather benign objects used with evil intent. Just as unplanned events such as hurricanes, earthquakes, fires, and user misuse have been codified into design requirements based on the likelihood and potential impact of the event, “evil intent” has to become part of the design process for buildings, vehicles, equipment, and other items. The endstate should be reasonable additions to existing codes and standards such that it is clear what is and is not designed for. In the absence of specific design guidance, professionals with appropriate expertise can assess potential for “evil intent” and provide recommendations to design out or warn against this potential harm to public safety, particularly when codified requirements are not present.

Use of the high-probability instructional sequence and escape extinction in a child with food refusal

We used the high-probability (high-p) instructional sequence with and without escape extinction in the treatment of food refusal. Acceptance increased and refusal decreased only with the introduction of escape extinction. These results raise important questions about the high-p sequence in the treatment of food refusal.     

Autonomy and Relatedness among Chinese Sojourners and Applicants: Conflictual or Independent Predictors of Well-Being and Adjustment?

Self-Determination Theory argues that relatedness and autonomy represent innate and universally critical needs and that, when satisfied, both needs should yield an independent positive effect on well-being and adjustment for all individuals. In contrast, some cross-cultural perspectives suggest that the pursuit of autonomy hampers the development of satisfying relationships, and such conflicts might be especially problematic for the well-being of individuals in collectivistic societies that value social bonds over the pursuit of uniqueness and independence. The present study sampled Chinese students who had temporarily moved to Belgium to study (i.e., sojourners) and Chinese students involved in the application procedure to study in Belgium (i.e., applicants). Consistent with SDT, the present research shows that the basic psychological needs for autonomy, relatedness, and competence are positively interrelated, that the satisfaction of these three needs predicts unique variance in Chinese students’ psychological well-being, vitality, and depression (i.e., main effects), and that autonomy satisfaction yields a more beneficial effect on vitality and better protects against depressive feelings when relatedness satisfaction is low (i.e., an interaction effect). Finally, mean-level differences in well-being between Chinese sojourners and applicants could be fully accounted by differential need satisfaction.

People with intellectual disability as neighbours: Towards understanding the mundane aspects of social integration

Although people with intellectual disabilities (ID) are increasingly expected to relocate from traditional institutional care to ‘regular’ neighbourhood housing facilities and socially integrate in these neighbourhoods, little is known about how they are perceived and appreciated as neighbours. This paper reports on interviews carried out with 30 neighbours without ID who were neighbours of small‐scale care facilities for people with ID. Interviews addressed the neighbours' everyday experiences of neighbouring in general, and neighbouring people with ID in particular. Neighbouring, for these informants, called for a fine balance between friendliness without over‐involvement. While they were generally positive about their interactions with their neighbours with ID, it emerged that the formal nature of the care facility and the interaction style of some of the neighbours with ID often contravened informants' assumptions about neighbouring. Informants expressed concern about a possible lack of appropriate distance, reciprocity and accountability among their neighbours with ID. The nature of the care facility, with paid staff, often group activities, formal means of achieving the everyday small tasks which neighbours sometimes do for each other, and a high turnover of residents, all undermined the possibility of a typical neighbourly relationship. In conclusion, we suggest that integration of people with ID into everyday neighbouring relationships raises complex challenges for care organizations that need to find a balance between supporting the needs of people with ID they care for, adequate support and mediation for other neighbours when necessary, and all the while avoid becoming overly involved in neighbouring as a formal partner.

National Identity and Attitude Toward Foreigners in a Multinational State: A Replication

An analysis of the 1995 Belgian General Election Survey indicates that the bipolar national identity variable, which contrasts citizens who identify exclusively with the Belgian nation with those who identify exclusively with the Flemish or Walloon subnation, measures not only the direction but also the intensity of national feelings. Respondents who are located at the middle of the scale tend to have a weak identification with both the nation and the subnation. On the basis of a structural equations modeling approach involving a test of the construct equivalence in the two regions and a control for agreeing-response bias, it is shown that the bipolar national identity variable and attitude toward foreigners are inversely related in Flanders and Wallonia. In Flanders, citizens with a strong subnational identification tend to have a negative attitude toward foreigners; those with a strong Belgian identification are more positive. This relationship became more pronounced after controlling for the respondents' level of education. In Wallonia, a reverse but less pronounced relationship was found. These findings support the hypothesis that the relationship between the variables of national identity and attitude toward foreigners is not intrinsic, but is at least partly determined by the social representation of the nation.
