Processing pronunciation variants: the role of probabilistic knowledge about lexical form and segmental co-occurrence

Two experiments investigated the contribution of lexical knowledge to processing nasal flap variants (e.g. “mental” produced as “mennle”). High and low variant production frequency nasal flap words and nonword counterparts were presented in a “t” detection task. More “t” detections were found in high than low variant frequency nasal flap words; no difference was found in control nasal flap nonwords but control nonwords with a nasal had more “t” detections than nonwords without a nasal. The findings suggest that access to lexical knowledge of an alternative NT pronunciation is modulated by variant frequency of the reduced form and pre-lexical phonotactic knowledge.     

Enhancing technologies: transformatio ad quod optimum?

The aim of the present paper is to bring out that the way in which we understand the enhancing and genetic interventions is closely related to the notion of health we adopt and this, in turn, to the worldview which underlies it. I explore the two notions of health which have prevailed since antiquity and which continue to co-exist in our era, and I point out that, if either of these makes sense, this is because each presupposes a different worldview with its own normative framework and moral values. As a consequence, when we argue about the enhancing interventions, we are not so much disagreeing about the application of this or that genetic technology as about the different ways in which we conceive our life and place in the world.     

Associations between authoritative parenting and the sun exposure and sun protective behaviours of adolescents and their friends

Associations between the sun exposure and sun protective behaviours of adolescents and their friends were examined along with the role played by authoritative parenting and other family and peer socialisation factors. Four hundred and two adolescents (198 males, 204 females) participated in the research. It was found that these adolescents and their friends shared similar sun exposure and sun protective behaviours and had similar parenting backgrounds. Parental authoritativeness was positively associated with the use of sun protection, even after the effects of other familial and peer variables were controlled, but not with the time spent sunbathing which was associated with friends' behaviours. The theoretical and practical implications of these findings are discussed.     

Approach/avoidance in dreams

The influential threat simulation theory (TST) asserts that dreaming yields adaptive advantage by providing a virtual environment in which threat-avoidance may be safely rehearsed. We have previously found the incidence of biologically threatening dreams to be around 20%, with successful threat avoidance occurring in approximately one-fifth of such dreams. TST asserts that threat avoidance is over-represented relative to other possible dream contents. To begin assessing this issue, we contrasted the incidence of 'avoidance' dreams with that of their opposite: 'approach' dreams. Because TST states that the threat-avoidance function is only fully activated in ecologically valid (biologically threatening) contexts, we also performed this contrast for populations living in both high- and low-threat environments. We find that 'approach' dreams are significantly more prevalent across both contexts. We suggest these results are more consistent with the view that dreaming is generated by reward-seeking systems than by fear-conditioning systems, although reward-seeking is clearly not the only factor determining the content of dreams.     

The time course of implicit and explicit concept learning

The present experiment investigated the development of implicit and explicit knowledge during concept learning. According to Cleeremans and Jiménez (2002), the content of a representation can be conscious only when the representation is of a sufficiently good quality; on this theory, increasing explicit and decreasing implicit knowledge might be expected with training. The view that implicit knowledge arises from compilation of explicit knowledge makes the opposite prediction. The present research tested these possibilities using subjective measures based on confidence ratings. One group of participants was presented with blocks of category exemplars that activated prior knowledge, whereas another group was presented with blocks of categories that did not elicit any useful prior knowledge. The results showed that, irrespective of the knowledge group participants were allocated to, explicit knowledge increased over the course of learning, whereas implicit knowledge either stayed the same or decreased, consistent with Cleeremans and Jiménez's prediction.     

Associations on dimensions of burnout and family support for a sample of Greek nurses

To assess correlations for perceived family support with burnout in Greek nurses, the Julkunen Family Support Questionnaire and the Maslach Burnout Inventory were administered to nurses (22 men and 88 women; M age = 35.6 yr., SD = 5.7 yr.; M work experience = 12.2 yr., SD = 6.2 yr.). The correlation was positive but low for family support and sense of personal accomplishment by women; all the other correlations were low, accounting for very small variance.     

Making sense of nonsense in British Sign Language (BSL): The contribution of different phonological parameters to sign recognition

Do all components of a sign contribute equally to its recognition? In the present study, misperceptions in the sign-spotting task (based on the word-spotting task; Cutler &; Norris, 1988) were analyzed to address this question. Three groups of deaf signers of British Sign Language (BSL) with different ages of acquisition (AoA) saw BSL signs combined with nonsense signs, along with combinations of two nonsense signs. They were asked to spot real signs and report what they had spotted. We will present an analysis of false alarms to the nonsense-sign combinations&;#x2014;that is, misperceptions of nonsense signs as real signs (cf. van Ooijen, 1996). Participants modified the movement and handshape parameters more than the location parameter. Within this pattern, however, there were differences as a function of AoA. These results show that the theoretical distinctions between formbased parameters in sign-language models have consequences for online processing. Vowels and consonants have different roles in speech recognition; similarly, it appears that movement, handshape, and location parameters contribute differentially to sign recognition.
