Optimism and Traumatic Stress: The Importance of Social Support and Coping1

This study examined the effects of optimism following traumatic stress and pathways through which optimism may act. Rescue and recovery workers at the crash site of US Air Flight 427 (n= 159) were studied 2, 6, 9, and 12 months after the crash to examine optimistic outlook, social support, coping, and stress. As predicted, a more optimistic disposition was associated with less self‐reported distress, less use of avoidant and wishful‐thinking coping strategies, greater use of problem‐focused and seeking‐social‐support coping, and greater availability of social support. Contrary to expectations, coping did not account for the relationships observed between optimism and stress responding. Social support explained some of the effects of optimism on coping and stress, but these mediational effects varied over time. Findings suggest that optimism affects stress and coping directly and indirectly by affecting how much social support is available.     

Differential outcomes training facilitates memory in people with Korsakoff and Prader-Willi syndromes

This article presents evidence that a teaching procedure called differential outcomes training enhances learning and memory. Differential outcomes training reinforces correct responses with outcomes that are unique and specific to the stimuli that are to be remembered. Teaching with this method enhances performance in people with Korsakoff syndrome and people with Prader-Willi syndrome, populations known to have lerning and working memory deficits. This initial evidence that persons with learning and memory deficits benefit from differential outcomes training should encourage future work on the development of an intervention using this type of training to aide daily functioning by people with learning and memory impairments.     

Practicing what we know: Multicultural counseling competence among clinical psychology trainees and experienced multicultural psychologists

Multicultural (MC) competence is considered a necessary skill for clinical and counseling psychologists; however, there is little to no research on the assessment of demonstrated multicultural counseling competence (DMCCC) of clinical psychology graduate students. In this study, we developed a MC assessment instrument to assess DMCCC of clinical psychology graduate students compared with MC-experienced psychologists. In addition, we assessed for differences between the endorsement of MC-appropriate strategies and actual use of these strategies in clinical practice, both by MC-experienced psychologists and clinical psychology students. Results revealed significant differences between the DMCCC of clinical psychology graduate students and MC-experienced psychologists. Significant differences also emerged between endorsement of strategies as multiculturally appropriate and likelihood of actual use of these strategies. Findings suggest that future training and competence models should incorporate participants' ability to not only identify multiculturally appropriate strategies but also use these strategies in therapy.     

Fluid intelligence, memory span, and temperament difficulties predict academic performance of young adolescents

There are several candidate measures when asking which psychological construct significantly predicts academic performance. Hundreds of studies have addressed this issue by measuring intelligence, basic cognitive processes, or personality. However, the simultaneous consideration of a broad and varied array of measures is much less common. Here we consider several cognitive and personality measures concurrently to define latent factors representing six constructs of presumed interest: fluid intelligence, short-term memory, working memory, processing speed, controlled attention, and temperament difficulties. One hundred and thirty-five secondary school students were tested. Their academic performance was measured by average grades in the nine scholastic areas of their curriculum. The main finding shows that a latent factor defined by fluid intelligence and memory span along with a latent factor defined by impulsiveness, sensation seeking, and lack of fear account for an impressive figure of 60% of the variance in academic performance.     

Training in Mindful Caregiving Transfers to Parent–Child Interactions

In an earlier study, we provided mindfulness training to three caregivers of individuals with profound multiple disabilities. We measured levels of happiness displayed by the individuals during the 8 weeks of mindfulness training of the caregivers, as well as during the 16 weeks following the termination of training. We found that happiness increased markedly when an individual interacted with a caregiver who had received training in mindfulness as opposed to a control caregiver who did not receive such training. In this study, we investigated whether the increased mindfulness of the three caregivers would transfer to interactions with their own children. The children’s non-compliance with their mother’s requests was used as an indirect index of the effects of training their mothers received in mindfulness. Although the ages of the children and their baseline levels of non-compliance were variable, the data showed a decrease in non-compliance during mindfulness training of the caregivers and further decreases following the completion of training. Our data provide preliminary evidence of transfer of mindfulness training from caregiving to parent–child interactions. We speculate as to why this may occur in mindfulness training.     

Biculturalism amongst ethnic minorities: Its impact for individuals and intergroup relations

This review article offers an integration of acculturation, biculturalism, and intergroup relations research. Additionally, it argues that bicultural identities can be more accurately conceptualised as a third, hyphenated cultural identity (e.g., Chinese‐Australian), in addition to one's ethnic and the dominant national identity. In doing so, this article proposes that hyphenated cultural identities may be personally meaningful for many ethnic minorities and discusses the function of hyphenated cultural identification for individuals and society. Given the relevance of bicultural identification, it is argued that recognising and understanding a hyphenated cultural identity is fundamental to ethnic minorities' wellbeing, as well as improving the quality of intergroup relations in multicultural societies, such as Australia.     

Evolution of the neural language network

The evolution of language correlates with distinct changes in the primate brain. The present article compares language-related brain regions and their white matter connectivity in the developing and mature human brain with the respective structures in the nonhuman primate brain. We will see that the functional specificity of the posterior portion of Broca’s area (Brodmann area [BA 44]) and its dorsal fiber connection to the temporal cortex, shown to support the processing of structural hierarchy in humans, makes a crucial neural difference between the species. This neural circuit may thus be fundamental for the human syntactic capacity as the core of language.     

Infants of depressed mothers show less “depressed” behavior with their nursery teachers

This study investigated whether infants' “depressed” behavior (i.e., less positive affect and lower activity levels) noted during their interactions with their depressed mothers generalized to their interactions with their nondepressed nursery teachers. Field et al. (1988) reported that infants of depressed mothers also show “depressed behavior” when interacting with nondepressed female adults, suggesting that the infants develop a generalized “depressed mood style” of interaction. However, in that study the adults were also strangers to the infants, confounding the results. In the present study, eighteen 3-month-old infants interacted with their depressed mothers and also with their nondepressed familiar teachers in 3-minute episodes. The infants' behavior ratings improved when they interacted with their familiar teachers compared to their interactions with their mothers. The infants' low activity levels and negative affect were specific to their interactions with their depressed mothers. Thus, the data suggest that the infants respond differentially to depressed and nondepressed adults who are familiar.     

Neighborhood frequency does affect performance in the Reicher task: encoding or decision?

Three experiments using the Reicher task show that performance on low-frequency words is disrupted if the incorrect alternative forms a higher frequency word. This neighborhood frequency effect occurs for both energy and pattern masks and for different sets of items. When the upcoming word is primed and its accessibility is enhanced, the neighborhood frequency effect is eliminated. Experiments 4a and 4b tested the neighborhood frequency effect using a same-different task and a signal-detection analysis. Neighborhood frequency affected the decision criterion but not the sensitivity of the perceptual system. Experiment 5 showed that many words with a frequency in the range from 1 to 5 per million are not recognized out of context. These results are consistent with the hypothesis that frequency effects in the Reicher task are caused by a bias in the decision system and can be simulated with the stochastic activation-verification model.
