Spousal interrelations in happiness in the Seattle Longitudinal Study: considerable similarities in levels and change over time

Development does not take place in isolation and is often interrelated with close others such as marital partners. To examine interrelations in spousal happiness across midlife and old age, we used 35-year longitudinal data from both members of 178 married couples in the Seattle Longitudinal Study. Latent growth curve models revealed sizeable spousal similarities not only in levels of happiness but also in how happiness changed over time. These spousal interrelations were considerably larger in size than those found among random pairs of women and men from the same sample. Results are in line with life-span theories emphasizing an interactive minds perspective by showing that adult happiness waxes and wanes in close association with the respective spouse. Our findings also complement previous individual-level work on age-related changes in well-being by pointing to the importance of using the couple as the unit of analysis.     

Use of multimodal imagery with precompetitive anxiety and stress of elite tennis players

The effect of multimodal imagery on anxiety and perceived stress was investigated in 46 male tennis players (16 to 18 yr.; M = 17.0, SD = 0.8). There were two groups, a multimodal imagery group and a control imagery group. The quasi-experimental design included pre- and post-treatment administrations of the 27-item Competitive State Anxiety Inventory to assess anxiety and the Perceived Stress Scale to assess stress. Analysis showed a statistically significant multivariate difference between the multimodal imagery and control groups on measures of cognitive anxiety, self-confidence, and perceived stress. Imagery plays a role in handling some specific types of anxiety and stress.     

Music therapy with hospitalized infants—the art and science of communicative musicality

Infants seek contingent, companionable interactions with others. Infants in a Neonatal Intensive Care Unit (NICU), while receiving care that optimizes their chances of survival, often do not have the kind of interactions that are optimal for their social development. Live music therapy (MT) with infants is an intervention that aims for contingent, social interaction between therapist and infant. This study, with a limited numbers of infants, examined the effectiveness of an MT intervention in the NICU at The Royal Children's Hospital Melbourne. Two groups of late pre‐term and full‐term infants were recruited to the study; one was given MT and the other was not. A healthy group of infants not given MT served as an additional control. The effect of MT was indexed using two measures reflecting infant social engagement: the Neurobehavioral Assessment of the Preterm Infant (NAPI) and the Alarm Distress Baby Scale (ADBB). Results suggest that the MT intervention used at The Royal Children's Hospital Melbourne supports infants' neurobehavioral development. In particular, hospitalized infants who received MT were better able to maintain self‐regulation during social interaction with an adult, were less irritable and cried less, and were more positive in their response to adult handling, when compared with infants who did not receive the intervention. These are important prerequisites for social interaction and development. Further and larger scale research using MT with this population is indicated.     

Are imaging and lesioning convergent methods for assessing functional specialisation?: investigations using an artificial neural network

This article presents an investigation of the relationship between lesioning and neuroimaging methods of assessing functional specialisation, using synthetic brain imaging (SBI) and lesioning of a connectionist network of past-tense formation. The model comprised two processing ‘routes’: one was a direct route between layers of input and output units, while the other, indirect, route featured an intermediate layer of processing units. Emergent specialisation within the network was assessed (1) by lesioning either the direct or indirect route and measuring past-tense performance for regular and irregular verbs, and (2) by measuring functional activation in each route when processing each verb type (SBI). SBI and lesioning approaches failed to converge when network activation was summed over each route in our SBI approach. Examination of individual network solutions suggested that the verb types might be using the indirect route differently in terms of the pattern of activation across the route, rather than in terms of gross activation. A subsequent SBI analysis compared patterns of activation in the indirect route and confirmed that these patterns were more similar between regular-type verbs than between regular and irregular verbs. As the spatial and temporal resolution of neuroimaging techniques improves, the results of this investigation suggest that the key to finding functional specialisation will be to distinguish local coding differences across behaviours that are the results of developmental processes. Other analyses suggest that lesioning data may be limited because, with increasing damage, they reveal the resting activations of a computational system rather than a computational specialisation per se.     

Social Antecedents of Children's Trustworthiness

A total of 1329 children were tested twice across 1 year (M = 7 years 5 months of age at Time 1 (T1)) in the Zurich Project on Social Development. The measures at T1 were corporal punishment, neighbourhood trustworthiness and children's trustworthiness (not lying/cheating and not stealing). At Time 2 (T2), children reported the promise keeping of their classmates, which, via social relations analyses, yielded evidence for individual differences in reliability trustworthiness. Structural equation modelling analyses confirmed that there was stability in children's trustworthiness as a latent variable. The structural equation modelling further yielded evidence that (1) corporal punishment at T1 was negatively associated with children's trustworthiness at T1 and negatively predicted changes in children's trustworthiness and (2) neighbourhood trustworthiness at T1 was positively associated with children's trustworthiness at T1 and positively predicted changes in children's trustworthiness. The findings yielded support for the hypotheses that corporal punishment negatively, and neighbourhood trustworthiness positively, contributes to the development of trustworthiness in children.

Substitution and pooling in crowding

Unless we fixate directly on it, it is hard to see an object among other objects. This breakdown in object recognition, called crowding, severely limits peripheral vision. The effect is more severe when objects are more similar. When observers mistake the identity of a target among flanker objects, they often report a flanker. Many have taken these flanker reports as evidence of internal substitution of the target by a flanker. Here, we ask observers to identify a target letter presented in between one similar and one dissimilar flanker letter. Simple substitution takes in only one letter, which is often the target but, by unwitting mistake, is sometimes a flanker. The opposite of substitution is pooling, which takes in more than one letter. Having taken only one letter, the substitution process knows only its identity, not its similarity to the target. Thus, it must report similar and dissimilar flankers equally often. Contrary to this prediction, the similar flanker is reported much more often than the dissimilar flanker, showing that rampant flanker substitution cannot account for most flanker reports. Mixture modeling shows that simple substitution can account for, at most, about half the trials. Pooling and nonpooling (simple substitution) together include all possible models of crowding. When observers are asked to identify a crowded object, at least half of their reports are pooled, based on a combination of information from target and flankers, rather than being based on a single letter.     

Personality Resemblance Between Parents and Offspring: Study of Five Factors Across Four Samples and Questionnaires

The aim of this study was to compare personality resemblance in four independent Croatian samples using the same family study design, but different measures of five-factor personality traits. The family study design can provide evidence of familial aggregation of personality and of assortative mating. Father-mother correlations, father-offspring correlations, mother-offspring correlations and regressions of offspring on midparent score were computed for five broad personality domains in each sample. Father-mother correlations ranged between ?.12 and .27 across different samples and questionnaires, while father-offspring correlations ranged between .04 and .34, mother-offspring correlations between ?.01 and .28 and regressions of offspring on midparent scores between .05 and .35. These results are congruent with earlier findings of: (a) low assortative mating for personality, and (b) moderate familial aggregation of personality, which is lower compared to heritability estimates from earlier studies using twin design. Familial aggregation is mostly comparable in size across four different five-factor questionnaires suggesting that, from a behavior genetic perspective, conclusions on family resemblance should not differ depending on the five-factor personality questionnaire used.     

Active versus passive maintenance of visual nonverbal memory

Forgetting over the short term has challenged researchers for more than a century, largely because of the difficulty of controlling what goes on within the memory retention interval. But the “recent-negative-probe” procedure offers a valuable paradigm, by examining the influences of (presumably) unattended memoranda from prior trials. Here we used a recent-probe task to investigate forgetting for visual nonverbal short-term memory. The target stimuli (two visually presented abstract shapes) on a trial were followed after a retention interval by a probe, and participants indicated whether the probe matched one of the target items. Proactive interference, and hence memory for old trial probes, was observed, whereby participants were slowed in rejecting a nonmatching probe on the current trial that nevertheless matched a target item on the previous trial (a recent-negative probe). The attraction of the paradigm is that, by uncovering proactive influences of past-trial probe stimuli, it can be argued that active maintenance in memory of those probes is unlikely. In two experiments, we recorded such proactive interference of prior-trial items over a range of interstimulus (ISI) and intertrial (ITI) intervals (between 1 and 6 s, respectively). Consistent with a proposed two-process memory conception (the active–passive memory model, or APM), actively maintained memories on current trials decayed, but passively “maintained,” or unattended, visual memories of stimuli on past trials did not.
