Learning the unlearnable: the role of missing evidence

Syntactic knowledge is widely held to be partially innate, rather than learned. In a classic example, it is sometimes argued that children know the proper use of anaphoric one, although that knowledge could not have been learned from experience. Lidz et al. [Lidz, J., Waxman, S., & Freedman, J. (2003). What infants know about syntax but couldn't have learned: Experimental evidence for syntactic structure at 18 months. Cognition, 89, B65-B73.] pursue this argument, and present corpus and experimental evidence that appears to support it; they conclude that specific aspects of this knowledge must be innate. We demonstrate, contra Lidz et al., that this knowledge may in fact be acquired from the input, through a simple Bayesian learning procedure. The learning procedure succeeds because it is sensitive to the absence of particular input patterns--an aspect of learning that is apparently overlooked by Lidz et al. More generally, we suggest that a prominent form of the "argument from poverty of the stimulus" suffers from the same oversight, and is as a result logically unsound.     

Relating the perception of visual ensemble statistics to individual levels of autistic traits

Integrating information across the visual field into an ensemble (e.g., seeing the forest from the trees) is an effective strategy to efficiently process the visual world, and one that is often impaired in autism spectrum disorder. Individual differences in sensory processing predict ensemble encoding, providing a potential mechanism for differing perceptual strategies across individuals, and possibly across diagnostic groups exhibiting atypical sensory processing. Here, we explore whether ensemble encoding is associated with traits associated with autism spectrum disorder (ASD). Participants (N=68) were presented with an ensemble display consisting of circles of varying sizes and colors, and were asked to remember the size of the red and blue circles, while ignoring the green circles. Participants were then cued to a target location after a brief delay, and instructed to report the remembered size of the circle they had previously viewed in that location, as ensemble information commonly biases memory for individual objects toward the probed mean of a set of similar objects. The Autism-spectrum Quotient (AQ) was completed to measure each individual’s level of autistic traits. We found that an individual’s level of ensemble perception, measured as their bias toward the probed mean, was negatively associated with a higher level of ASD traits. These results suggest that individuals with higher levels of ASD traits are less likely to integrate perceptual information. These findings may shed light on different perceptual processing within the autism spectrum, and provide insight into the relationship between individual differences and ensemble encoding.

The Impact of Stigma and Social Support on Development of Post-traumatic Growth Among Persons Living with HIV

Given high rates of trauma in people living with HIV (PLH) and the health benefits of posttraumatic growth (PTG), understanding how to foster PTG in PLH exposed to trauma could be of interest to clinical psychologists working with this population. The current study examined factors theoretically related to development of PTG in PLH, namely HIV-related stigma, disclosure of HIV status, and emotional support. A sample of 334 HIV-positive adults answered a battery of self-report questionnaires. HIV-related stigma, disclosure to sexual partners, and emotional support were significant predictors of PTG: stigma was associated with lower PTG, whereas disclosure and emotional support were associated with higher PTG. Disclosure and emotional support remained significantly associated with PTG in the model including demographic factors and stigma. These findings highlight the need for development of interventions that can aid PLH in disclosing their HIV status to sexual partners and increasing available social support.     

“Like sheep for the slaughter”

The primary objective of this article is to investigate how a Lutheran theology supports the soldier’s vocation in war. First, the analysis is made in relation to the concept of larva Dei, second, in relation to “the pastorate” and “technology of power”. By the interaction, I show how Luther’s theology can be used as a critique towards Foucault and vice versa. Through this narrative method, structures of power and liberation are unveiled. The interaction illuminates their diverse views on secular and non-secular order, as well as an immanent and transcendental order. Luther points towards eternity, while Foucault points towards society and its powers. The main outcome is firstly: faith for Foucault is never an explanation of “reality”, but a result of social relations. For Luther, faith is to experience the world as reality; and secondly: larva Dei creates a possibility to overcome suffering by faith, whereas by Foucault’s immanent structure, suffering is understood as “empty” or “meaningless”. Foucault contributes with an important critique of misusing vocation in war. An area for further research is to continue developing critiques of vocation and power in relation to contemporary soldiers’, terrorists’ and anarchists’ masks, since some are used to protect life and others to protect identities.     

Too much – not enough. The representation of the body and the meaning of symptoms in patients with eating disorders

Eating disorders cover different clinical syndromes, all of which are characterized by an immense focus on food, body and weight, an endless attempt to combat the body and by a fluctuation between ‘too much and not enough’ on different levels (e.g., behaviourally, mentally, physically).

The aim of this article is to contribute to the psychoanalytic understanding of eating disorders, to highlight the vital importance of the symptoms as a psychological survival strategy and to illustrate similarities between eating disordered patients as well as the very different pathways that can lead to an eating disorder. Two clinical cases are presented, one very shortly and one in more detail.     

Exploring Temporal Progression of Events Using Eye Tracking

This study investigates the representation of the temporal progression of events by means of the causal change in a patient. Subjects were asked to verify the relationship between adjectives denoting a source and resulting feature of a patient. The features were presented either chronologically or inversely to a primed event context given by a verb (to cut: long–short vs. short–long). Effects on response time and on eye movement data show that the relationship between features presented chronologically is verified more easily than that between features presented inversely. Post hoc, however, we found that the effects of temporal order occurred only when subjects read the features more than once. Then, the relationship between the features is matched with the causal change implied by the event context (contextual strategy). When subjects read the features only once, subjects respond to the relationship between the features without taking into account the event context.     

Prospective Pilot Study of the Mastering Each New Direction Psychosocial Family Systems Program for Pediatric Chronic Illness

Psychosocial interventions for pediatric chronic illness (CI) have been shown to support health management. Interventions that include a family systems approach offer potentially stronger and more sustainable improvements. This study explores the biopsychosocial benefits of a novel family systems psychosocial intervention (MEND: Mastering Each New Direction). Forty‐five families participated in a 21‐session intensive outpatient family systems‐based program for pediatric CI. Within this single arm design, families were measured on five domains of Health‐Related Quality of Life (HRQL) self‐report measures; Stress, Cognitive Functioning, Mental Health, Child HRQL, Family Functioning. Both survey and biological measures (stress: catecholamine) were used in the study. Results from multivariate general linear models showed positive pre‐, post‐, and 3‐month posteffects in all five domains. The program effects ranged from small to moderate (η² = .07–.64). The largest program effects were seen in the domains of cognitive functioning (η² = .64) and stress (η² = .27). Also, between disease groups, differences are noted and future implications for research and clinical practice are discussed. Conclusions suggest that the MEND program may be useful in helping families manage pediatric chronic illnesses. Study results also add to the growing body of literature suggesting that psychosocial interventions for pediatric chronic illness benefit from a family systems level of intervention.
