Making Space,Offering Voice

By looking closely at the biblical narrative of the man born blind (John 9:1‐41), this article raises how Jesus enables and promotes the participation and, even more so, the leadership of people with disabilities in God’s transformative mission in the church and the world. Through examining each scene in the story through a disability lens, this article aims to challenge the church on how it views leaders with disabilities in God's mission, making space for our voices and our witness as disciples of Christ.     

Shaping the Enemy: Foundational Labelling by L.E.J. Brouwer and A. Heyting

The use of the three labels (logicism, formalism, intuitionism) to denote the three foundational schools of the early twentieth century are now part of literature. Yet, neither their number nor their adoption has been stable over the twentieth century. They were not introduced by the founding fathers of each school: namely, neither Frege nor Russell spoke of ‘logicism’; and even Hilbert did not use the word ‘formalism’ to introduce his foundational programs. At a certain point, only Brouwer used the label ‘intuitionism’ in his scientific production to personify his philosophy of mathematics and he used the label ‘formalism’ for Hilbert’s foundational viewpoint. Starting with Brouwer, the origin of the use of the three labels to represent a foundational meaning, will be analysed in this paper. Thereafter, the role that Brouwer’s pupil Arend Heyting had in the production and use of foundational labels will be considered. On the basis of the comparison of the attitudes of these two scholars I will finally advance the thesis that not only the creation but also the use of labels, far from being a mere gesture of academic reference to literature, can be a sign of the cultural operation each scholar wanted to do.     

Reflective Capacity: An Antidote to Structural Racism Cultivated Through Mental Health Consultation

Effecting a paradigm shift from “reproductive health” to “reproductive justice” within the perinatal field requires changes simultaneously at the levels of the individual healthcare provider and the system of care. The Infant-Parent Program at the University of California, San Francisco (UCSF) has extended its pioneering infant and early childhood mental health consultation to perinatal service systems applying an infant mental health approach to programs caring for expecting and new parents. In partnership with two nursing programs, UCSF consultants direct their efforts at supporting reflective practice capacities and use-of-self in patient–provider relationships. Both nursing programs serve vulnerable groups of expectant and new parents who grapple with challenges to health and well-being stemming from structural racism. As reflective capacities are supported within the consultation case conferences, providers spontaneously identify the need for tools to effectively address issues of race, class, and culture and to combat structural racism throughout the healthcare system. Policies and procedures that uphold structural racism cease to be tolerable to providers who bring their full selves to the work that they are trained to do. Using these nurse consultation partnerships as organizational case studies, this article describes a range of challenges that arise for providers and delineates steps to effective engagement toward reproductive justice.     

Generalisation of threat expectancy increases with time

Excessive fear generalisation is a feature characteristic of clinical anxiety and has been linked to its aetiology. Previous animal studies have shown that the mere passage of time increases fear generalisation and that brief exposure to training cues prior to long-term testing reverses this effect. The current study examined these phenomena in humans. Healthy participants learned the relationship between the presentation of a picture of a neutral male face and the delivery of a mild shock. One group was immediately tested with a novel picture of a somewhat different male face (generalisation test). Another group was tested one week later. A third group was also tested one week later and was additionally exposed to the training picture prior to testing. During picture presentations, shock-expectancy ratings were obtained as a measure of fear. Fear generalisation increased from the immediate test to the 1-week follow-up test. This result could not be attributed to level of neuroticism or a general increase in fear (incubation). Furthermore, the time-dependent increase in fear generalisation vanished following brief exposure to the training picture. Results indicate that human fear generalisation is a temporally dynamic process and that memory for stimulus details can be re-established following a reminder treatment.     

Hemispheric asymmetries in semantic processing: evidence from false memories for ambiguous words

We used fMRI to investigate competition during language production in two word production tasks: object naming and color naming of achromatic line drawings. Generally, fMRI activation was higher for color naming. The line drawings were followed by a word (the distractor word) that referred to either the object, a related object, or an unrelated object. The effect of the distractor word on the BOLD response was qualitatively different for the two tasks. The activation pattern suggests two different kinds of competition during lexical retrieval: (1) Task-relevant responses (e.g., red in color naming) compete with task-irrelevant responses (i.e., the object’s name). This competition effect was dominant in prefrontal cortex. (2) Multiple task-relevant responses (i.e., target word and distractor word) compete for selection. This competition effect was dominant in ventral temporal cortex. This study provides further evidence for the distinct roles of frontal and temporal cortex in language production, while highlighting the effects of competition, albeit from different sources, in both regions.     

Hippocampal theta (3-8Hz) activity during classical eyeblink conditioning in rabbits

In 1978, Berry and Thompson showed that the amount of theta (3–8 Hz) activity in the spontaneous hippocampal EEG predicted learning rate in subsequent eyeblink conditioning in rabbits. More recently, the absence of theta activity during the training trial has been shown to have a detrimental effect on learning rate. Here, we aimed to further explore the relationship between theta activity and classical eyeblink conditioning by determining how the relative power of hippocampal theta activity [theta/(theta + delta) ratio] changes during both unpaired control and paired training phases. We found that animals with a higher hippocampal theta ratio immediately before conditioning learned faster and also that in these animals the theta ratio was higher throughout both experimental phases. In fact, while the hippocampal theta ratio remained stable in the fast learners as a function of training, it decreased in the slow learners already during unpaired training. In addition, the presence of hippocampal theta activity enhanced the hippocampal model of the conditioned response (CR) and seemed to be beneficial for CR performance in terms of peak latency during conditioning, but did not have any effect when the animals showed asymptotic learning. Together with earlier findings, these results imply that the behavioral state in which hippocampal theta activity is absent is detrimental for learning, and that the behavioral state in which hippocampal theta activity dominates is beneficial for learning, at least before a well-learned state is achieved.     

Dissociating cue-related and task-related processes in task inhibition: evidence from using a 2:1 cue-to-task mapping.

Performance of task sequences is assumed to rely on activation and inhibition of tasks. An empirical marker of task inhibition is the so-called n-2 repetition cost, which is assessed by comparing performance in trial n-2 task repetitions (i.e., ABA) with that in n-2 task switches (i.e., CBA). Current theoretical accounts assume that inhibition acts on the level of task representations (i.e., task sets). However, another potential target of task inhibition could be the representation of the task cue. To decide between these two alternatives, the authors used a 2:1 cue-to-task mapping design. They found significant n-2 task repetition costs both with n-2 cue repetitions and n-2 cue switches. These costs were about equal (Experiment 1), and this data pattern was found for both short and long cuing intervals (Experiment 2). Together, the data suggest that task inhibition acts on task sets and not on cue representations.     

Maternal Antisocial Behavior, Parenting Practices, and Behavior Problems in Boys at Risk for Antisocial Behavior

We investigated the independent contributions of maternal history of antisocial behavior and parenting practices to the worsening course of sons' behavior problems in a sample of young urban boys at risk for antisocial behavior. Mothers reported on boys' behavior problems at baseline and one year later, as well as on their own history of antisocial behavior before and after age 15, and of lifetime depression and substance use disorders (provisional DSM-III-R diagnoses). Baseline reports of parenting practices were obtained. Lower involvement, lower monitoring, and higher levels of parent–child conflict and maternal Conduct Disorder (CD) before age 15 contributed to the worsening of boys' behavior problems one year later; mothers' symptoms of Antisocial Personality Disorder after age 15 did not. Mothers' lifetime history of Major Depression and Substance Use Disorder did not add to the worsening of boys' behavior problems after accounting for these other factors. Although maternal CD contributed directly to the worsening of boys' behavior problems, the effect of parenting was more substantial. We discuss clinical implications for prevention and treatment of children's antisocial behavior, and intergenerational implications of girls' early antisocial behavior.     

Acquiring a cognitive skill with a new repeating version of the Tower of London task.

A computerized version of the Tower of London task was used to investigate cognitive skill learning. Thirty-six healthy volunteers were assigned to either a random condition (nonrecurring problems), or to a sequence condition in which, unbeknownst to the subjects, a repeating sequence of three problems was presented. Indices of execution, planning, and total time, as well as number of moves performed, were used to measure behavioural change. Subjects' performance improved in both conditions across blocks of practice. A distinct learning effect related to the repeating sequence was also observed. This suggests that a specific skill that reflects procedural learning of the strategies, rules, and procedures pertaining to repeating problems can develop over and above a more general skill at solving cognitive planning problems with practice.
