Attachment to objects as compensation for close others' perceived unreliability

Attachment theory posits that close interpersonal relationships provide people with psychological security across the lifespan. Research shows that when people perceive that close others are unreliable, they may seek alternative, non-social sources of security (e.g., deities). Building on this work, the authors hypothesized that attachment to objects compensates for threatened attachment security when close others are unreliable. Participants primed with close others', but not strangers', unreliability reported increased attachment to belongings (Study 1), and this effect was mediated by feelings of attachment anxiety (concern over close others' availability), but not attachment avoidance (avoiding emotional dependence; Study 2), suggesting that object attachment compensates for the perception that close others are unreliable rather than consistently rejecting. In Study 3, when a valued belonging was removed, participants primed with uncertainty about their relationships showed increased separation anxiety and motivation to reunite with the belonging, regardless of the belonging's perceived importance for facilitating relationships.     

Electrical stimulation superimposed on voluntary training can limit sensory integration in neural adaptations

ABSTRACT P. Bezerra, S. Zhou, Z. Crowley, A. Davie, and R. Baglin (2011) suggested that the neural mechanisms responsible for steadiness improvement relate in particular to the discharge behavior of motor units and the practice and learning of skills rather than the strength gain after electromyostimulation superimposed over voluntary training. However, the afferent inputs are determining in control of the force level produced and thus contribute to ensure muscle steadiness. Hence, it is possible that electromyostimulation interferes in neurophysiological afference integration and prevents neural adaptations that enable improvement of the control of force (and then muscle steadiness) to occur. Therefore, the neural adaptations induced by electromyostimulation superimposed onto voluntary training should also be researched in relation to the sensory pathways.     

Effects of speed of word processing on semantic access: the case of bilingualism

Bilingual speakers generally manifest slower word recognition than monolinguals. We investigated the consequences of the word processing speed on semantic access in bilinguals. The paradigm involved a stream of English words and pseudowords presented in succession at a constant rate. English-Welsh bilinguals and English monolinguals were asked to count the number of letters in pseudowords and actively disregard words. They were not explicitly told that pairs of words in immediate succession were embedded and could either be semantically related or not. We expected that slower word processing in bilinguals would result in semantic access indexed by semantic priming. As expected, bilinguals showed significant semantic priming, indexed by an N400 modulation, whilst monolinguals did not. Moreover, bilinguals were slower in performing the task. The results suggest that bilinguals cannot discriminate between pseudowords and words without accessing semantic information whereas monolinguals can dismiss English words on the basis of subsemantic information.     

The social costs of punishment

Lab experiments on punishment are of limited relevance for understanding cooperative behavior in the real world. In real interactions, punishment is not cheap, but the costs of punishment are of a different nature than in experiments. They do not correspond to direct payments or payoff deductions, but they arise from the repercussions punishment has on social networks and future interactions.     

The ability of children to delay gratification in an exchange task

The ability to wait for a reward is a necessary capacity for economic transactions. This study is an age-related investigation of children's ability to delay gratification in an exchange task requiring them to wait for a significant reward. We gave 252 children aged 2-4 a small piece of cookie, then offered them an opportunity to wait for a predetermined delay period before exchanging it for a larger one. In a first experiment, the children had to exchange the initial food item for rewards two, four or eight times larger. Results showed that children aged 3-4 years old sustained longer time lags for larger rewards than for smaller rewards. This effect was not found in 2-year-old subjects. In a second experiment, a reward 40 times larger than the initial piece was offered to determine the maximum waiting time that children could sustain. All age groups increased their performances. Older children were more successful at waiting, but some children as young as 2 years old were able to tolerate delays of up to 16 min. Older children who chose to give up waiting earlier than their known capacity demonstrated anticipation skills which had not been seen in younger children, showing that they had anticipated an increase in the time lag, and that they had considered both time and reward value when making their decision. Despite the age effect, we did not establish any limits for delaying gratification in children. This study may have educational implications for dealing with behavioral misconduct, which is known to be related to impulsivity control in young children.     

Preparation of forefinger’s sequence on keyboard orients ocular fixations on computer screen

This study examined the links between attention, hand movements and eye movements when performed in different spatial areas. Participants performed a visual search task on a computer screen while preparing to press two keyboard keys sequentially with their index. Results showed that the planning of the manual sequence influenced the latency of the first saccade and the placement of the first fixation. In particular, even if the first fixation placement was influenced by the combination of both components of the prepared manual sequence in some trials, it was affected principally by the first component of the prepared manual sequence. Moreover, the probability that the first fixation placement did reflect a combination of both components of the manual sequence was correlated with the speed of the second component. This finding suggests that the preparation of the second component of the sequence influence simultaneous oculomotor behavior when motor control of the manual sequence relied on proactive motor planning. These results are discussed taking into account the current debate on the eye/hand coordination research.     

This Is Like That: Metaphors in Public Discourse Shape Attitudes

A metaphoric framing is a message comparing an abstract concept (e.g., the economy) to a dissimilar concept that is more concrete and easier to comprehend (e.g., a vehicle). Metaphoric framings are commonly used in public discourse (e.g., magazine editorials, political campaign advertisements) to communicate about controversial sociopolitical issues. These messages are not mere figures of speech. Mounting evidence shows that even brief exposure to a metaphoric framing can prompt observers to transfer their knowledge of the metaphor's concrete concept to interpret analogous features of the target issue, even though the two concepts are superficially quite different. This article reviews this evidence, demonstrating that the metaphors pervading everyday communication uniquely shape how people think and feel about a host of important issues. The authors draw on theories of motivated social cognition to chart avenues for future research on the situational factors that moderate metaphor's impact on attitudes.     

Effects of school‐based mindfulness training on emotion processing and well‐being in adolescents: evidence from event‐related potentials

In a non‐randomized controlled study, we investigated the efficacy of a school‐based mindfulness curriculum delivered by schoolteachers to older secondary school students (16–18 years). We measured changes in emotion processing indexed by P3b event‐related potential (ERP) modulations in an affective oddball task using static human faces. ERPs were recorded to happy and sad face oddballs presented in a stimulus stream of frequent faces with neutral expression, before and after 8 weeks of mindfulness training. Whilst the mean amplitude of the P3b, an ERP component typically elicited by infrequent oddballs, decreased between testing sessions in the control group, it remained unchanged in the training group. Significant increases in self‐reported well‐being and fewer doctor visits for mental health support were also reported in the training group as compared to controls. The observed habituation to emotional stimuli in controls thus contrasted with maintained sensitivity in mindfulness‐trained students. These results suggest that in‐school mindfulness training for adolescents has scope for increasing awareness of socially relevant emotional stimuli, irrespective of valence, and thus may decrease vulnerability to depression.
