Extending Everything with Nothing

Philosophia - In this paper we offer a new solution to the old paradox of nothingness. This new solution develops in two steps. The first step consists in showing how to resolve the contradiction...     

Binocular detection of masked patterns in young and old observers

A visual pattern embedded in noise is detected appreciably better when the stimulus complex contains interocular cues (dichoptic condition) than when such cues are absent (binoptic condition). In a recent study (F. Speranza, G. Moraglia, & B. A. Schneider, 1995) the authors showed that the relative difference between binoptic and dichoptic thresholds does not change with age. However, older adults showed higher binoptic and dichoptic thresholds, thus suggesting an age-related difficulty with degraded stimulation. In this article the authors first replicated these findings and proceeded next to investigating whether age-related changes in processing efficiency, additive internal noise, and the spatial frequency bandwidth of the detecting filters could account, separately or concurrently, for the elevated thresholds in noise exhibited by the older adults. Results indicate that this increase is not attributable to age-related changes in filter bandwidth or internal noise. Rather, the findings can be explained in terms of a decrease in processing efficiency with age.     

Space coding for sensorimotor transformations can emerge through unsupervised learning

The posterior parietal cortex (PPC) is fundamental for sensorimotor transformations because it combines multiple sensory inputs and posture signals into different spatial reference frames that drive motor programming. Here, we present a computational model mimicking the sensorimotor transformations occurring in the PPC. A recurrent neural network with one layer of hidden neurons (restricted Boltzmann machine) learned a stochastic generative model of the sensory data without supervision. After the unsupervised learning phase, the activity of the hidden neurons was used to compute a motor program (a population code on a bidimensional map) through a simple linear projection and delta rule learning. The average motor error, calculated as the difference between the expected and the computed output, was less than 3°. Importantly, analyses of the hidden neurons revealed gain-modulated visual receptive fields, thereby showing that space coding for sensorimotor transformations similar to that observed in the PPC can emerge through unsupervised learning. These results suggest that gain modulation is an efficient coding strategy to integrate visual and postural information toward the generation of motor commands.     

“Is Our Daughter Crazy or Bad?”: A Case Study of Therapeutic Assessment with Children

In this paper we present a new model of intervention with documented efficacy that combines psychological tests and assessment methods with therapeutic techniques to promote change in clients. We will discuss Therapeutic Assessment of Children and their families (TA-C) through the case of a 4-year-old girl, Clara, and her family. Clara’s parents were distressed by her uncontrollable rage outbursts and feared she might be “crazy”. The treatment helped to shift the narrative the parents had about Clara and give new meanings to her behaviors. We describe in detail the steps of the assessment and provide a theoretical discussion of the therapeutic processes involved.     

Rapid naming,not cancellation speed or articulation rate,predicts reading in an orthographically regular language (Italian)

This study examined the influence of rapid automatization naming (RAN) measures on various parameters of reading performance in children who were native speakers of a language with a shallow orthography (Italian). Participants included 281 children enrolled in first-to-sixth grade. They were given a Naming test, in which they had to name rapidly matrices of colors, objects, or digits, a Cancellation test, using the same stimulus materials, and an oral Articulation test. Performance on all tests improved steadily across ages tested. Performance on the Naming test, but not on the Cancellation and Articulation tests, predicted speed and accuracy in reading; none of these measures reliably predicted the reading comprehension measure. Data on a Blending test were also available for a subsample of first- and third-graders. Both RAN and phonological ability contributed independently to the prediction of reading ability (accuracy and speed) in these participants. The results extend observations on RAN to an orthographically shallow language (Italian) and suggest an element of continuity between languages with opaque and transparent orthographies.     

Justify your love: testing an online STI-risk communication intervention designed to promote condom use and STI-testing

The efficacy of a tailored, web-based intervention communicating the risks of sexually transmitted infections (STI) for heterosexual young adults was examined in a randomised, controlled trial. The main aims of the relationship-oriented intervention were to influence risk perceptions and to promote (maintenance of) condom use and STI-testing among young adults who reported being recently engaged in a heterosexual relationship. The intervention addressed risk perceptions, attitudes, normative beliefs, self-efficacy and skills related to condom use and STI-testing. Outcomes were compared immediately after the intervention (N = 171) and 3 months later (N = 115) to a non-tailored intervention group and to a control group. Cognitive and behavioural outcomes showed that the tailored intervention was efficacious in influencing perceived susceptibility to STI and STI-testing intentions immediately after the intervention, and in reducing rates of unprotected sex at 3 months.     

Exploring Children's Induced Defensiveness to the Tell Me a Story Test (TEMAS)

This study examined the effect of inducing a defensive attitude (fake good) in children on their responses to the Tell Me a Story test (TEMAS; Costantino, Malgady, &; Rogler, 1988 Costantino, G., Malgady, R. G., &; Rogler, L. H. (1988). TEMAS (Tell-Me-A-Story) manual. Los Angeles, CA: Western Psychological Services. [Google Scholar]). Different story elicitation procedures were employed to explore their efficacy for inducing a defensive response style in children. Eighty-four Italian children aged 8 to 10 years old completed the TEMAS and the L scale of the Behavioral Assessment Scale for Children–2 (BASC–2; Reynolds &; Kamphaus, 2004 Reynolds, C. R., &; Kamphaus, R. W. (2004). BASC–2: Behavior Assessment System for Children (2nd ed.). Circle Pines, MN: American Guidance Service. [Google Scholar]), which were used to detect the adoption of a defensive attitude. Children completed the tests under 1 of 3 conditions: (a) honest condition, (b) fake good with verbal instructions, and (c) fake good with verbal instructions and visual stimuli illustrating what was verbally explained. Using simultaneous verbal instructions and visual stimuli facilitated children's understanding of the researcher's instructions compared to using verbal stimuli alone. Results showed that children instructed to fake good used less time to tell stories and tended to modify the simpler and more face valid aspects of their stories. Still, 29 out of 47 children failed to fake good on the BASC–2 L scale. More complex TEMAS variables showed no significant difference between story elicitation conditions.     

Nothingness,Meinongianism and inconsistent mereology

Synthese - Within the framework of Meinongianism, nothingness turns out to have contradictory features—it seems to be an object and not. In this paper, we explore two different kinds of...
