Early language outcomes in Argentinean toddlers: Associations with home literacy,screen exposure and joint media engagement

This study aimed to analyse the contribution of mothers' home literacy beliefs and practices and the quantity and quality of screen media exposure on Argentinean toddler's language. In addition, we considered parent–child joint engagement, as well as adult scaffolding behaviours during the use of electronic devices. A total of 465 mothers of 18–36 months old children completed an online survey including: the MacArthur Bates CDI, home literacy, screen exposure, joint engagement and scaffolding questionnaires. We observed positive effects of literacy beliefs, PC times and verbal scaffolding on language outcomes. TV exposure contributed negatively to vocabulary and, along with educational content, to sentence use. Shared reading and screen media experiences can be an opportunity for language stimulation, provided there is dialogue and joint engagement. Passive screen exposure and inadequate content may be detrimental for toddlers' language outcomes, probably by displacement of socially significant interactions.     

Come with me: experimental evidence for intentional recruitment in Tonkean macaques

Animal Cognition - Recruitment is a process by which animals can initiate collective movements: the action of an individual prompts conspecifics to follow. Although it has been hypothesized that...     

Privacy and the Computer: Why We Need Privacy in the Information Society

For more than thirty years an extensive and significant philosophical debate about the notion of privacy has been going on. Therefore it seems puzzling that most current authors on information technology and privacy assume that all individuals intuitively know why privacy is important. This assumption allows privacy to be seen as a liberal "nice to have" value: something that can easily be discarded in the face of other really important matters like national security, the doing of justice and the effective administration of the state and the corporation. In this paper I want to argue that there is something fundamental in the notion of privacy and that due to the profoundness of the notion it merits extraordinary measures of protection and overt support. I will also argue that the notion of transparency (as advocated by Wasserstrom) is a useless concept without privacy and that accountability and transparency can only be meaningful if encapsulated in the context of privacy. From philosophical and legal literature I will discuss and argue the value of privacy as the essential context and foundation of human autonomy in social relationships. In the conclusion of the paper I will discuss implications of this notion of privacy for the information society in general, and for the discipline of information systems in particular.     

Puerperal psychosis: Vulnerability and aftermath

The puerperium is a particularly vulnerable time for a depressive psychotic breakdown, with important consequences for both mother and child. While general psychiatric experience helps in the overall management, psychoanalytic insights help towards understanding the central psychopathology. Illustrative case-studies are presented.

Based on hospital admission rates, puerperal psychosis is regarded as a rare condition (one in 500 deliveries). In this paper, evidence is given to suggest that puerperal psychosis is a far commoner condition (three in 100 deliveries), and that many less-severe cases remain undetected and untreated in the community. It is argued that understanding interventions in these cases can be therapeutic for the mother, as well as having major implications for the baby's development.     

THE MANAGEMENT OF DEPRESSION – ANALYTIC,ANTIDEPRESSANTS OR BOTH?

Patients with depression cover the spectrum, in terms of severity of psychopathology, between those receptive to analytic psychotherapy and those that require treatment with medication. In this paper, the author demonstrates how an analytic framework of understanding has a place in the latter group, and can aid general psychiatrists in relation to their depressed patients. It will be demonstrated, with clinical illustrations, how analytic thinking can help to make sense of many of the symptoms of depression, including early-morning wakening, diurnal mood variation, agoraphobia and hypochondriasis. It is also important to help the supportive relative with their countertransference experiences, when their partner is undergoing a depressive episode. Finally, the notion of a pathological ego-destructive superego taking over the driving-seat in depression is explored. The need to unseat it and replace it with a more mature superego provides an overall framework of approach to the treatment of depression.     

Culture of honour theory and social anxiety: Cross-regional and sex differences in relationships among honour-concerns,social anxiety and reactive aggression

According to the Appraisal-Tendency Framework (Han, Lerner, & Keltner, 2007), certainty-associated emotions increase risk taking compared with uncertainty-associated emotions. To date, this general effect has only been shown in static judgement and decision-making paradigms; therefore, the present study tested the effect of certainty on risk taking in a sequential decision-making task. We hypothesised that the effect would be reversed due to the kind of processing involved, as certainty is considered to encourage heuristic processing that takes into account the emotional cues arising from previous decisions, whereas uncertainty leads to more systematic processing. One hundred and one female participants were induced to feel one of three emotions (film clips) before performing a decision-making task involving risk (Game of Dice Task; Brand et al., 2005). As expected, the angry and happy participants (certainty-associated emotions) were more likely than the fearful participants (uncertainty-associated emotion) to make safe decisions (vs. risky decisions).     

fMRI evidence for dorsal stream processing abnormality in adults born preterm

We investigated the consequences of premature birth on the functional neuroanatomy of the dorsal stream of visual processing. fMRI was recorded while sixteen healthy participants, 8 (two men) adults (19 years 6 months old, SD 10 months) born premature (mean gestational age 30 weeks), referred to as Premas, and 8 (two men) matched controls (20 years 1 month old, SD 13 months), performed a 1-back memory task of Object or Grip information using a hand grasping a drinking vessel as stimulus. While history of prematurity did not significantly affect task performance, Group by Task analysis of variance in regions of interest spanning the occipital, temporal and parietal lobes revealed main effects of Task and interactions between the two factors. Object processing activated the left inferior occipital cortex and bilateral ventral temporal regions, belonging to the ventral stream, with no effect of Group. Grip processing across groups activated the early visual cortex and the left supramarginal gyrus belonging to the dorsal stream. Group effect on the brain activity during Grip suggested that Controls represented the actions’ goal while Premas relied more on low-level visual information. This shift from higher- to lower-order visual processing between Controls and Premas may reflect a more general trend, in which Premas inadequately recruit higher-order visual functions for dorsal stream task performance, and rely more on lower-level functions.     

Methods for comparing scanpaths and saliency maps: strengths and weaknesses

In this article, we are interested in the computational modeling of visual attention. We report methods commonly used to assess the performance of these kinds of models. We survey the strengths and weaknesses of common assessment methods based on diachronic eye-tracking data. We then illustrate the use of some methods to benchmark computational models of visual attention.
