Intra-Individual Variability Among Children with ADHD on a Working Memory Task: An Ex-Gaussian Approach

Intra-individual variability on a computer-based working memory task was examined among 25 children/adolescents with ADHD and 24 typically developing peers. Participants completed the Visual Serial Addition Task (VSAT) and reaction time data were fit to an ex-Gaussian distribution. ADHD participants demonstrated significantly more variable performance than controls, and effects of working memory load were observed. Event rate, however, had no influence on group differences in performance. Follow-up correlations revealed associations between VSAT performance and ADHD symptomatology. This study supports intra-individual variability as a hallmark feature of ADHD beyond the domain of response inhibition and reinforces the need to consider variability in ADHD more broadly.     

The Test of Variables of Attention (TOVA): Internal Consistency (Q1 vs. Q2 and Q3 vs. Q4) in Children with Attention Deficit/Hyperactivity Disorder (ADHD)

The internal consistency of the Test of Variables of Attention (TOVA) was examined in a cohort of 6- to 12-year-old children (N = 63) strictly diagnosed with ADHD. The internal consistency of errors of omission (OMM), errors of commission (COM), response time (RT), and response time variability (RTV) of different test conditions (stimulus infrequent condition [Q₁ vs. Q₂] and stimulus frequent condition [Q₃ vs. Q₄]) was assessed via correlation analyses. All TOVA index scores under investigation assessing its internal consistency exhibited statistically significant correlations. All correlations fell in the moderate-high range.     

Perceiving vocal age and gender: An adaptation approach

Aftereffects of adaptation have revealed both independent and interactive coding of facial signals including identity and expression or gender and age. By contrast, interactive processing of non-linguistic features in voices has rarely been investigated. Here we studied bidirectional cross-categorical aftereffects of adaptation to vocal age and gender. Prolonged exposure to young (~ 20 yrs) or old (~ 70 yrs) male or female voices biased perception of subsequent test voices away from the adapting age (Exp. 1) and the adapting gender (Exp. 2). Relative to gender-congruent adaptor-test pairings, vocal age aftereffects (VAAEs) were reduced but remained significant when voice gender changed between adaptation and test. This suggests that the VAAE relies on both gender-specific and gender-independent age representations for male and female voices. By contrast, voice gender aftereffects (VGAEs) were not modulated by age-congruency of adaptor and test voices (Exp. 2). Instead, young voice adaptors generally induced larger VGAEs than old voice adaptors. This suggests that young voices are particularly efficient gender adaptors, likely reflecting more pronounced sexual dimorphism in these voices. In sum, our findings demonstrate how high-level processing of vocal age and gender is partially intertwined.     

Future Contradictions

A common and much-explored thought is ?ukasiewicz's idea that the future is ‘indeterminate’—i.e., ‘gappy’ with respect to some claims—and that such indeterminacy bleeds back into the present in the form of gappy ‘future contingent’ claims. What is uncommon, and to my knowledge unexplored, is the dual idea of an overdeterminate future—one which is ‘glutty’ with respect to some claims. While the direct dual, with future gluts bleeding back into the present, is worth noting, my central aim is simply to sketch and briefly explore an alternative glutty-future view, one that is conservative—indeed, entirely classical—with respect to the present.

The structure of the paper runs as follows. §1 briefly sketches the target gap picture of an indeterminate future yielding gappy claims at the present. §2 presents the direct dual idea—a glut picture of an overdeterminate future yielding glutty claims at present. §3 sketches the central idea, a more interesting glut picture in which the future contains contradictory states but the present remains entirely classical. §4 contains a general defence of the idea, leaving it open as to whether the gappy-future view enjoys substantive virtues over the proposed glutty-future view of §3.     

Robert Burns in the counsellor's chair: A socio-cultural analysis of the Burns myth

To illustrate how difficult endings are, this paper first cites an Italian therapist's experience of the use of time with university students in Naples and then associates to contrasting examples in the novel, art, music and the cinema. It uses a dialogue about ending in the film Brief Encounter as a possible paradigm for what is needed in brief therapy. It then refers to the work of James Mann on different experiences of time which underlie the resistance to brief work. How can brief therapy contain the paradox between finite and infinite time? Incorporating another model of therapeutic intervention with the use of Milton Erickson's attitude to time and the unconscious, the paper then moves on to a clinical example, where treatment consisted of an assessment and five sessions. Here the practice of not interpreting the transference is challenged, along with an exploration of the concept of transference to the organization and the use of pre-treatment ‘maternal reverie’ associations. Using the combination of informal trance-like states with a clear focus on the ‘here and now’, the process of the therapeutic relationship is then worked with in the case material.     

The im-possibility of secular critique: The future of religion's memory

The legacy of secular critique, with its Greek, Christian, Kantian, modernist traces, constitutes an aporetic law (or contradiction). That law is this: a critical legacy, if it is critical, can affirm and sustain itself only by trying to separate it from itself (from the very crisis that it is). The legacy or history of ‘religion’ is always a history of such critique. Such a legacy always anticipates critiquing itself, its memory (of whatever kind – racist, sexist, colonialist, nationalist). Such a legacy of critique is always a legacy of crisis. However, the crisis of such a legacy cannot be resolved, because critique, as kairos/krisis (critical/decisive moment), can admit of no resolution. Yet the (secular) history of religion, if it is ever historical, can only be a history of such aporetic critique. Such an aporetic critique will be the heritage of religion's im-possible ¹ ?1. I write the word impossible/impossibility with and without a hyphen. When I hyphenate im-possible, I do so to remain true to Derrida's use of it. The im-possible is irreducible to either possibility or impossibility. Sometimes Derrida also writes the word without hyphenating it, but he still implies such irreducibility. future. It is an im-possible future because it will always be a promise, a promise to separate it from itself, a promise that will remain always deferred, always to come. Today, the promise of this secular critique is (in) democracy with its sovereign ‘decisive’ politics. We can no longer simply critique the (future) legacy of religion, understood this way. To do so is to fulfil that legacy's own messianic wish. This is the aporetic limit of secular critique. To think at the limits of the legacy of the critique of religion is to think the very question of the (secular) history of ‘religion’ and its others, that is, ‘religions’.     

Test anxiety and comprehension efficiency: The role of prior knowledge and working memory deficits

The hypotheses that test anxiety is associated with a deficit in prior knowledge and/or working memory capacity, that anxiety impairs comprehension efficiency, and that deficits in knowledge and capacity underlie the efficiency impairment, were tested. In Study 1, high-anxiety students were characterized by lower scores in several vocabulary measures, compared with low-anxiety students. In Study 2, high-anxiety individuals showed inferior working memory capacity to low-anxiety individuals under evaluative stress conditions, but not under non-stress conditions. In Study 3 high-anxiety subjects exhibited lower efficiency scores than low-anxiety subjects in expository texts without a summary: The former employed a greater amount of reading time than the latter to acquire an equivalent amount of information. In addition, the disadvantage in efficiency associated with anxiety was removed when differences in vocabulary knowledge were partialled out statistically. Instead, that disadvantage was only reduced, but not eliminated, when differences in transitory working memory capacity were partialled out. Therefore, the prior knowledge deficit hypothesis accounts for the impairment in reading efficiency associated with high anxiety better than the transitory working memory reduction hypothesis.     

Belief–logic conflict resolution in syllogistic reasoning: Inspection-time evidence for a parallel-process model

An experiment is reported examining dual-process models of belief bias in syllogistic reasoning using a problem complexity manipulation and an inspection-time method to monitor processing latencies for premises and conclusions. Endorsement rates indicated increased belief bias on complex problems, a finding that runs counter to the “belief-first” selective scrutiny model, but which is consistent with other theories, including “reasoning-first” and “parallel-process” models. Inspection-time data revealed a number of effects that, again, arbitrated against the selective scrutiny model. The most striking inspection-time result was an interaction between logic and belief on premise-processing times, whereby belief – logic conflict problems promoted increased latencies relative to non-conflict problems. This finding challenges belief-first and reasoning-first models, but is directly predicted by parallel-process models, which assume that the outputs of simultaneous heuristic and analytic processing streams lead to an awareness of belief – logic conflicts than then require time-consuming resolution.     

Hornsby and Baker on the physicalist orthodoxy

I examine some recent claims put forward by L. A. Paul, Barry Dainton and Simon Prosser, to the effect that perceptual experiences of movement and change involve an (apparent) experience of ‘passage’, in the sense at issue in debates about the metaphysics of time. Paul, Dainton and Prosser all argue that this supposed feature of perceptual experience – call it a phenomenology of passage – is illusory, thereby defending the view that there is no such a thing as passage, conceived of as a feature of mind-independent reality. I suggest that in fact there is no such phenomenology of passage in the first place. There is, however, a specific structural aspect of the phenomenology of perceptual experiences of movement and change that can explain how one might mistakenly come to the belief that such experiences do involve a phenomenology of passage.     

Positive psychology: Past,present, and (possible) future

A survey study and two experiments were done to test the hypothesis that social flow is more enjoyable than solitary flow. In the survey study it was found that recalled social flow experiences were rated more enjoyable than solitary flow experiences. In the first experiment when challenge and skill were the same across social and solitary conditions, social flow was reported to be more enjoyable than solitary flow. In the second experiment when the level of social interdependence was manipulated it was found that participants in highly interdependent teams reported more joy in flow than individuals performing less interdependently. In both experiments, people playing simple paddleball games reported and expressed more joy performing with others than alone. Taken together, the three investigations support the conclusion that doing it together is better than doing it alone. Solitary flow, while quite enjoyable, is not as enjoyable as social flow.
