Relationship Education for Military Couples: A Pilot Randomized Controlled Trial of the Effects of Couple CARE in Uniform

Military life can place excess strain on couple relationships. The Couple CARE relationship education program was tailored to address the challenges of military couples. Thirty-two Australian military couples participated in a pilot feasibility study assessing the Couple CARE in Uniform adaptation against an active control. Relationship satisfaction and communication improved in both conditions, with no significant difference between the conditions. Couples' high relationship satisfaction on presentation, paired with modest statistical power, might have contributed to the null results. However, Couple CARE in Uniform had significantly higher consumer satisfaction than the comparison condition, suggesting it is a program worthy of further evaluation.     

Rooting for (and Then Abandoning) the Underdog

Although people prefer to associate with winners, there is also a strong desire to support the lovable loser or underdog. In 4 studies, we demonstrate the underdog effect and its delimiting conditions. In Studies 1 and 2, participants rooted for the underdog in judgments of athletic, business, and artistic competition. In Study 3, participants watched animated clips of struggling and nonstruggling geometric shapes. The results showed that participants showed more rooting, sympathy, and identification with struggling shapes than with nonstruggling ones. Study 4 identified conditions under which people abandon the underdog, showing that participants rooted for the underdog only when both self‐relevance and consequences were high. Theoretical implications of these findings are discussed.     

Neuroimaging evidence for agenda-dependent monitoring of different features during short-term source memory tests

A short-term source monitoring procedure with functional magnetic resonance imaging assessed neural activity when participants made judgments about the format of 1 of 4 studied items (picture, word), the encoding task performed (cost, place), or whether an item was old or new. The results support findings from long-term memory studies showing that left anterior ventrolateral prefrontal cortex (PFC) is engaged when people make source attributions about reflectively generated information (cognitive operations, conceptual features). The findings also point to a role for right lateral PFC in attention to perceptual features and/or familiarity in making source decisions. Activity in posterior regions also differed depending on what was evaluated. These results provide neuroimaging evidence for theoretical approaches emphasizing that agendas influence which features are monitored during remembering (e.g., M. K. Johnson, S. Hashtroudi, & D. S. Lindsay, 1993). They also support the hypothesis that some of the activity in left lateral PFC and posterior regions associated with remembering specific information is not unique to long-term memory but rather is associated with agenda-driven source monitoring processes common to working memory and long-term memory.     

Effort discounting in human nucleus accumbens

A great deal of behavioral and economic research suggests that the value attached to a reward stands in inverse relation to the amount of effort required to obtain it, a principle known as effort discounting. In the present article, we present the first direct evidence for a neural analogue of effort discounting. We used fMRI to measure neural responses to monetary rewards in the human nucleus accumbens (NAcc), a structure previously demonstrated to encode reference-dependent reward information. The magnitude of accumbens activation was found to vary with both reward outcome and the degree of mental effort demanded to obtain individual rewards. For a fixed level of reward, the NAcc was less strongly activated following a high-demand for effort than following a low demand. The magnitude of this effect was noted to correlate with preceding activation in the dorsal anterior cingulate cortex, a region that has been proposed to monitor information-processing demands and to mediate in the subjective experience of effort.

Children and adolescents coordinate group and moral concerns within different goal contexts when allocating resources

Coordinating complex social and moral concerns when allocating resources is a key issue in late childhood and early adolescence. This study explored resource allocation in three goal contexts that required children to focus to differing degrees on moral and group concerns. Children (9–11-years, M^age = 9.84, n = 190) and adolescents (14–16-years, M^age = 14.92, n = 154) were informed their school peer group held an in-group norm (competition, cooperation). Participants allocated resources between their in-group and an outgroup within one of three goal contexts (prosocial, learning-focused, and group-focused). Participants allocated in favour of their in-group to achieve a prosocial goal but attenuated this when the goal was focused on learning and cooperation. Adolescents, more than children, reasoned about the goals of resource allocation to justify their decisions. From 9 years old, children begin to coordinate peer group norms and goal information when deciding how to allocate resources within intergroup contexts.     

Children's Sleep Behavior Scale: normative data on 870 children in grades 1 to 6

A 22-item Likert-type rating scale for parents was developed for screening a broad range of specific sleep-related behaviors of elementary school children. The prevalence of these behaviors was reported by parents for boys (n = 459) and girls (n = 411) in three age groups, less than 8.5 yr., between 8.5 and 11.5 yr., and greater than 11.5 yr. For all age groups, the most prevalent behaviors were restlessness, waking up at night, pleasant dreams, getting up to go to the bathroom, talking while asleep, and complaints about not being able to sleep, while the least frequent were rhythmical movements and crying while asleep. The self-reports suggest that many of the behaviors are underestimated in the literature. Some sex and age differences were found, but the number of siblings, birth order, change in family structure, and educational status of father and mother were unrelated to the sleep variables. Test-retest reliabilities of self-reports by these parents to individual items were adequate.     

Food-search behavior and its relation to the central excitatory state in the genetic analysis of the blow fly Phormia regina

Dethier (1957) described an aspect of food-search behavior in Phormia regina as the blow fly dance. A hungry fly walks in relatively straight lines with its proboscis retracted until it encounters food (sucrose). After ingesting even a small amount of sucrose, the fly begins making frequent, tight turns, flexes its front tarsi to bring more chemosensory hairs into contact with the substrate and repeatedly extends and retracts its proboscis. Like the central excitatory state (CES), which causes an increase in proboscis extensions to water when a fly is stimulated with sucrose, the dance lasts longer in hungrier flies or with higher sucrose concentrations. It was considered that dance behavior might be an ethologically relevant manifestation of CES. In order to test this hypothesis, dance duration in lines selected for high- and low-CES levels was measured. As predicted, flies from the high-CES line danced longer than those from the low-CES line, and the CES-dance correlation in individual flies was high. This phenotypic correlation disappeared in the F2 generation of a cross between the high- and low-CES lines, a result indicating that the observed variations in CES and dance duration were not caused by the same set of genes. Further characterization of the underlying genetic system showed that several linked autosomal genes with digenic epistatic interactions and a complex pattern of maternal inheritance were responsible for the difference in dance durations between the high- and low-CES lines.     

Assessing teaching opportunities in a residential treatment facility

Seventeen living units in a residential treatment facility for developmentally disabled persons were assessed to determine the availability of teaching opportunities during the course of a normal day's routine. Teaching opportunities exist when the environment is arranged so that residents can participate in the ongoing activities. The teaching opportunities are identified within components that are recognizable activities that occur routinely and have a functional purpose. An assessment form was constructed as a means for documenting teachng opportunities. Assessments were conducted continuously from early morning through evening activities. The results of the assessments suggested that two approaches to resident care were in operation at the facility: one was characterized by a traditional care/custodial model, the other was characterized by a teaching model. On units where the number of teaching opportunities available was high, there was a smaller percentage of unstructured time, i.e., blocks of time when opportunities to engage in structured activities were not available to the residents.
