Eye movements reveal no immediate “WOW” (“which one's weird”) effect in autism spectrum disorder

Autism spectrum disorder (ASD) and typically developed (TD) adult participants viewed pairs of scenes for a simple “spot the difference” (STD) and a complex “which one's weird” (WOW) task. There were no group differences in the STD task. In the WOW task, the ASD group took longer to respond manually and to begin fixating the target “weird” region. Additionally, as indexed by the first-fixation duration into the target region, the ASD group failed to “pick up” immediately on what was “weird”. The findings are discussed with reference to the complex information processing theory of ASD (Minshew & Goldstein, 1998 Minshew, N. J. and Goldstein, G. 1998. Autism as a disorder or complex information processing. Mental Retardation and Developmental Disabilities Research Reviews, 4: 129–136. [Crossref] , [Google Scholar]).     

High-performers use the phonological loop less to process mental arithmetic during working memory tasks

This study investigated the effects of three working memory components—the central executive, phonological loop, and visuospatial sketchpad—on performance differences in complex mental arithmetic between individuals. Using the dual-task method, we examined how performance during two-digit addition was affected by load on the central executive (random tapping condition), phonological loop (articulatory suppression condition), and visuospatial sketchpad (spatial tapping condition) compared to that under no load (control condition) in high- and low-performers of complex mental arithmetic in Experiment 1. Low-performers showed an increase in errors under the random tapping and articulatory suppression conditions, whereas high-performers showed an increase of errors only under the random tapping condition. In Experiment 2, we conducted similar experiments on only the high-performers but used a shorter presentation time of each number. We found the same pattern for performing complex mental arithmetic as seen in Experiment 1. These results indicate that high-performers might reduce their dependence on the phonological loop, because the central executive enables them to choose a strategy in which they use less working memory capacity.     

Computer-based Testing and Training with Scenarios from Complex Problem-solving Research: Advantages and Disadvantages

The use of PC-based simulations for selection and training for jobs which require complex problem solving skills is ever-increasing. This paper gives a short review of such simulations along with a list of advantages and disadvantages of their use. Possible future developments are sketched.     

Phantom narratives and the uncanny in cultural life: psychic presences and their shadows

Abstract

In this paper the author explores the emotional factors that are activated at the level of the cultural unconscious, that produce experiences of the uncanny that are expressed through Phantom Narratives. Phantom Narratives as a hybridized term is the author’s way of linking personal and social activity of unconscious story formation through psychic presences (images). Phantom Narratives are expressions of the unconscious at the level of the group that shows the psyche’s way of narrating its relationship to the group, through the expressions of cultural, social, and political issues. The uncanny, at the level of the social, is seen as those disturbances of feelings that alienate us from the familiar social world of others. What is uncanny about Phantom Narratives is how group emotional dynamics are represented as psychic presences. Making use of the author’s own subjectivity (i.e. psychoanalytic literary genre) he uses an approach from analytic psychology (Jungian) called amplification, which allows for the elaboration of symbolic processes, to create a meaningful (semantic) context for exploration.     

Domain-specific interference between storage and processing in complex span is driven by cognitive and motor operations

The role of domain-specific interference in the complex-span paradigm is still controversial. Here we distinguish two operations within the processing task of this paradigm—a cognitive operation to solve the task and a motor operation to give the answer. Their domain-specific interference with maintenance was investigated within the complex-span paradigm. Presentation of the memoranda—six words or four spatially distributed dots—was interleaved with the presentation of letter pairs to be processed. Cognitive operation domain was manipulated by asking participants to make either a rhyme judgment or a symmetry judgment for each letter pair. Motor operation domain was varied by requiring a response by either speaking or pointing. Cognitive load was held constant. Cognitive and motor operation showed separate domain-specific effects on memory: Visuospatial memory was impaired more by visuospatial than verbal cognitive operations and more by manual–spatial than oral motor operations. In contrast, verbal memory performance was worse when verbal cognitive operations and oral motor operations were executed. The results are discussed in relation to the multicomponent model, the time-based resource-sharing (TBRS) model, and the Serial Order in a Box–Complex-Span (SOB-CS) model. They imply that models of working memory must incorporate mechanisms that allow for domain-specific interference in the verbal and the visuospatial domain.     

Stupidity in the analytic field: Vicissitudes of the detachment process in adolescence

This paper has the objective of broadening the understanding of technical aspects in working with adolescents who defend themselves against detachment from infantile aspects through defensive organizations. These organizations numb the adolescent toward both triangular reality and narcissistic defenses. The families of such young people may be part of the organization and the analyst can also be recruited to participate in it. But the analyst's perception can become blurry and this fact makes him appear stupid. Aspects of the myths of Narcissus and Oedipus are used here as models for studying stupidity. The analysis of a psychotic teenage girl who is symbiotic in relation to her family shows how the analytical field can be invaded by defensive configurations. Collusions of idealization and domination/submission involve the young person, her family and the analyst but the defensive organizations are only identified after their traumatic breakdown. The expansion of the symbolic network allows symbiotic transgenerational organizations to be identified, while models related to enactments prove helpful for understanding technical ups and downs. The paper ends with imaginative conjectures where Oedipus, as ‘patient’, is compared to the patient discussed here. These conjectures lead to reinterpretations of aspects of the Oedipus myth. The reinterpretations, together with the theoretical and clinical study, may serve as models for understanding the technical ups and downs in working with troubled teens.     

Influence of gait mode and body orientation on following a walking avatar

Regulating distance with a moving object or person is a key component of human movement and of skillful interpersonal coordination. The current set of experiments aimed to assess the role of gait mode and body orientation on distance regulation using a cyclical locomotor tracking task in which participants followed a virtual leader. In the first experiment, participants moved in the backward-forward direction while the body orientation of the virtual leader was manipulated (i.e., facing towards, or away from the follower), hence imposing an incongruence in gait mode between leader and follower. Distance regulation was spatially less accurate when followers walked backwards. Additionally, a clear trade-off was found between spatial leader-follower accuracy and temporal synchrony. Any perceptual effects were overshadowed by the effect of one’s gait mode. In the second experiment we examined lateral following. The results suggested that lateral following was also constrained strongly by perceptual information presented by the leader. Together, these findings demonstrated how locomotor tracking depends on gait mode, but also on the body orientation of whoever is being followed.     

Infantile Sexuality, Primary Object-Love and the Anthropological Signifi Cance of the Oedipus Complex: Re-Reading Freud's 'Female Sexuality'

The author attempts to show why and in what respect Freud's famous article 'Female sexuality' can still be a source of inspiration for a contemporary metapsychology. In this text, Freud acknowledges the importance of the child's tie to its mother for the fi rst time. Both Balint and Bowlby consider this text to be a distant forerunner of their own theories on primary object-love and attachment respectively. At the same time, Freud's text contains some elements of a 'theory of generalized seduction' as it was developed in the last decades by Jean Laplanche. 'Female sexuality' therefore presents itself as the perfect point of departure for a discussion of the relation between primary object-love (and attachment) and sexuality. Based on his reading of Freud's text, the author argues that human subjectivity is characterized by the lack of attunement between the world of the adult and the world of the child. This insight allows for a reformulation of the anthropological signifi cance of the Oedipus and castration complexes. They are no longer interpreted as universal problems that every child has to face, but as historical and contingent solutions to the lack of attunement between the child and the adult that is essential to human subjectivity.     

High regularities in eye-movement patterns reveal the dynamics of the visual working memory allocation mechanism

With only two to five slots of visual working memory (VWM), humans are able to quickly solve complex visual problems to near optimal solutions. To explain the paradox between tightly constrained VWM and impressively complex human visual problem-solving ability, we propose several principles for dynamic VWM allocation. In particular, we propose that complex visual information is represented in a temporal manner using only a few slots of VWM that include global and local visual chunks. We built a model of human traveling salesman problem solving based on these principles of VWM allocation and tested the model with eye-movement data. Exactly as the model predicted, human eye movements during traveling salesman problem solving have precise quantitative regularities with regard to both the general statistical pattern of attentional fixations and how they vary across individuals with different VWM capacities. Even though VWM capacity is very limited, eye movements dynamically allocate VWM resources to both local and global information, enabling attention to fine details without loss of the big picture.
