Joint attention,shared goals,and social bonding

There has recently been interest in the ways in which coordinated movements encourage coactors to feel socially closer to one another, but this has generally overlooked the importance of necessary precursors to this joint action. Here we target two low‐level behaviours involved in social coordination that may mediate a relationship between joint actions and social bonding, namely joint attention and shared goals. Participants engaged in a simple reaction time task while sitting next to a partner performing the same task. In a joint attention condition, both participants attended to stimuli presented on the same half of a computer screen, while in a control condition, they attended to opposite sides of the computer screen. Shared goals were manipulated by giving participants the instruction to keep below a threshold score for both individual response times and accuracy (individual goal), or their joint mean response time and accuracy (i.e., averaging their mean response time and accuracy with that of their partner: shared goal). Attending to the same side of the screen led to higher ratings on a composite social bonding index directed towards a partner, while shared goals did not cause any effects on partner ratings. Joint attention was sufficient to encourage social closeness with an interaction partner, which suggests that any activities which encourage attending to the same point in space could have some influence on how connected coactors feel about one another.     

The Use of Cognitive, Emotive and Behavioral Interventions in Rational Emotive Behavior Therapy When Clients Lack “Emotional” Insight

Rational Emotive Behavior Therapy practitioners from around the world reported their use of cognitive, emotive, behavioral, or other interventions, both in sessions and as homework when responding to clients who reported intellectual insight but were not moved by it. Practitioners were exceptionally prone to using cognitive interventions during sessions and not particularly inclined toward emotive interventions either during sessions or as homework.     

Social norms in adolescent risk engagement and recommendation

Social influence is an important determinant of adolescent risk-taking, but little is known about how social norms contribute to adolescents’ tendency to recommend and engage in risky behaviours. Using the Adolescent Risk-taking Questionnaire, we assessed subjects’ (n = 198, age = 10–26) propensity to engage in and recommend risk-taking as well as their perception of risk norms. Adolescents recommended risk-taking more often compared to children and young adults. Perceived social norms were the most important factor predicting engagement in risky behaviours, and adolescents perceived risk-taking to be more normative than children or adults. Our findings highlight two mechanisms that contribute to adolescent risk-taking, active recommendation and perceived social norms. On this basis, we discuss potential means to attenuate excessive adolescent risk-taking.     

Semantic access in number word translation: the role of crosslingual lexical similarity

The revised hierarchical model of bilingualism (e.g., Kroll & Stewart, 1994) assumes that second language (L2) words primarily access semantics through their first language (L1) translation equivalents. Consequently, backward translation from L2 to L1 should not imply semantic access but occurs through lexical wordform associations. However, recent research with Dutch-French bilinguals showed that both backward and forward translation of number words yields a semantic number magnitude effect (Duyck & Brysbaert, 2004), providing evidence for strong form-to-meaning mappings of L2 number words. In two number-word translation experiments with Dutch-English-German trilinguals, the present study investigated whether semantic access in L1-L2 and L1-L3 number-word translation depends on lexical similarity of the languages involved. We found that backward translation from these more similar language pairs to L1 still yields a semantic magnitude effect, whereas forward translation does not, in contrast with the Dutch-French results of Duyck and Brysbaert (2004). We argue against a dual route model of word translation and suggest that the degree of semantic activation in translation depends on lexical form overlap between translation equivalents.     

Fairness considerations: Increasing understanding of intentionality during adolescence

The development of fairness considerations in decision making is not well understood. Here we tested the hypothesis that increased understanding of intentionality during adolescence underlies increased fairness considerations in social decision making. We conducted three experiments using an adapted version of the Ultimatum Game with participants during four stages of adolescence: 9, 12, 15, and 18 years of age. Participants made or evaluated monetary offers, and we manipulated the intentionality context of offers. Results show that strategic thinking is already present at 9 years of age. There was no age difference in fairness of offers when the responder could not reject an offer (Experiment 1), but when they could reject an offer there was an age-related increase in taking into account the perspective and intentionality of other players when making offers (Experiment 2) and evaluating offers (Experiment 3). Taken together, the results demonstrate a linear developmental transition in fairness considerations that may have important implications for our understanding of social interactions during adolescence.     

Let it be? Pain control attempts critically amplify attention to somatosensory input

Psychological Research - Recent studies have suggested that the threat of pain may redirect attention towards specific features of the pain stimulus via attentional control settings. For instance,...     

Haptic and visual perception of roughness

In this study, we are interested in the following two questions: (1) how does perceived roughness correlate with physical roughness, and (2) how do visually and haptically perceived roughness compare? We used 96 samples of everyday materials, such as wood, paper, glass, sandpaper, ceramics, foams, textiles, etc. The samples were characterized by various different physical roughness measures, all determined from accurately measured roughness profiles. These measures consisted of spectral densities measured at different spatial scales and industrial roughness standards (R(a), R(q) and R(z)). In separate haptic and visual conditions, 12 na?ve subjects were instructed to order the 96 samples according to perceived roughness. The rank orders of both conditions were correlated with the various physical roughness measures. With most physical roughness measures, haptic and visual correspondence with the physical ordering was about equal. With others, haptic correspondence was slightly better. It turned out that different subjects ordered the samples using different criteria; for some subjects the correlation was better with roughness measures that were based on higher spatial frequencies, while others seemed to be paying more attention to the lower spatial frequencies. Also, physical roughness was not found to be the same as perceived roughness.     

Motor-Skill Learning in Alzheimer’s Disease: A Review with an Eye to the Clinical Practice

Since elderly people suffering from dementia want to go on living independently for as long as possible, they need to be able to maintain familiar and learn new practical skills. Although explicit or declarative learning methods are mostly used to train new skills, it is hypothesized that implicit or procedural techniques may be more effective in this population. The present review discusses 23 experimental studies on implicit motor-skill learning in patients with Alzheimer’s disease (AD). All studies found intact implicit motor-learning capacities. Subsequently, it is elaborated how these intact learning abilities can be exploited in the patients’ rehabilitation with respect to the variables ‘practice’ and ‘feedback.’ Recommendations for future research are provided, and it is concluded that if training programs are adjusted to specific needs and abilities, older people with AD are well able to (re)learn practical motor skills, which may enhance their autonomy.
