An internet survey of emotional health,treatment seeking and barriers to accessing mental health treatment among Chinese-speaking international students in Australia

The present internet survey examined the demographic characteristics of Chinese-speaking international students in Australia, psychological distress levels as measured by the Kessler-10 (K-10) Item scale, help-seeking history and preferences, as well as treatment barriers. Of the 144 respondents, 54% reported high psychological distress (mean K-10 score?=?23.96; SD?=?9.03). However, only 9% of those who were highly distressed reported they had sought mental health services in the past year. While the majority preferred help from informal social networks, they tended to favour mental health services over traditional culture-specific forms of help. Common barriers to accessing mental health services reported by respondents with high psychological distress included costs or transportation concerns, limited knowledge of available services, time constraints, the perception that symptoms were not severe enough to warrant treatment, language difficulties and lack of knowledge of symptoms of psychological distress. Although the majority preferred face-to-face treatments over internet treatments, a considerable percentage of respondents were willing to try either treatment modality. Chinese-speaking international students are a high risk group for developing psychological distress, yet they tend to underuse mental health services. Education about the effectiveness of face-to-face and online treatments may increase treatment seeking by this population.     

One-to-one support for crisis intervention using online synchronous instant messaging: evaluating working alliance and client satisfaction

Young people are increasingly turning to online support, especially when traditional mental health services are not immediately available. Using a cross-sectional design, sociodemographic information and self-reported perceptions of the strength of the working alliance and client satisfaction were collected from a sample of participants (n = 78) who were users of a service providing free online support using synchronous instant messaging. The results reported a significant positive relationship between the strength of the working alliance and client satisfaction, suggesting that the strength of the working alliance remains a key component in counselling, even online. Participants, however, scored significantly lower on both the strength of the working alliance and client satisfaction, compared to participants in offline settings as reported in past studies.     

Does the Narrative Style of Video Evidence Influence Judgements About Rape Complainant Testimony?

Four studies investigated lawyers' concerns that the narrative style of police interviews with adult rape complainants reduces the impact of this interview as video evidence. Study 1 (N = 96) compared mock juror perceptions of simulated evidence‐in‐chief either in traditional short‐answer or narrative style and found testimony style was not a predictor of complainant credibility. Studies 2 (N = 104), 3 (N = 102) and 4 (N = 102) examined different variables that change with testimony style—the number of questions asked, overall testimony length and response length. The number of questions asked was the only predictor of complainant credibility; more questions resulted in higher credibility ratings. These findings suggest that lawyers' concerns about narrative style interviewing are unwarranted. Copyright © 2015 John Wiley & Sons, Ltd.     

Post-retrieval effects of icv infusions of hemicholinium in mice are dependent on the age of the original memory

CF-1 male mice were trained in an inhibitory avoidance task using a high footshock (1,2 mA, 50 Hz, 1 sec) in order to reduce the influence of extinction on retention performance. At 2, 7, 14, or 30 d after training, the first retention test was performed and hemicholinium (HC-3, 1.0 microg/mice), a specific inhibitor of high-affinity choline uptake in brain cholinergic neurons, was given intracerebroventricularly immediately after. Twenty four hours after treatment, mice were tested in an inhibitory avoidance task during five consecutive days, each 24 h apart. Retention performance was impaired by HC-3 when the first re-exposure took place at 2, 7, or 14 d, but the effect was no longer seen when re-exposure occurred 30 d after training. We did not find spontaneous recovery 21 d after training, when memory was retrieved 2 d after training and HC-3 was given immediately after. Although we cannot definitively discard a retrieval deficit, this lack of spontaneous recovery is in accordance with the storage-deficit interpretation. These results confirm and extend previous ones, suggesting that central cholinergic mechanisms are involved in the hypothetical reconsolidation memory processes of an inhibitory avoidance task in mice and also suggest that this participation depends on the "age" of the original memory trace. This implies that the vulnerability of a reactivated memory to a specific treatment, as the one used in this study, inversely correlates with the age of the original memory, and it is likely to determine memory reconsolidation processes.     

Neural bases of binocular rivalry

During binocular rivalry, conflicting monocular images compete for access to consciousness in a stochastic, dynamical fashion. Recent human neuroimaging and psychophysical studies suggest that rivalry entails competitive interactions at multiple neural sites, including sites that retain eye-selective information. Rivalry greatly suppresses activity in the ventral pathway and attenuates visual adaptation to form and motion; nonetheless, some information about the suppressed stimulus reaches higher brain areas. Although rivalry depends on low-level inhibitory interactions, high-level excitatory influences promoting perceptual grouping and selective attention can extend the local dominance of a stimulus over space and time. Inhibitory and excitatory circuits considered within a hybrid model might account for the paradoxical properties of binocular rivalry and provide insights into the neural bases of visual awareness itself.     

Language and the perception of emotion

Three studies assessed the relationship between language and the perception of emotion. The authors predicted and found that the accessibility of emotion words influenced participants' speed or accuracy in perceiving facial behaviors depicting emotion. Specifically, emotion words were either primed or temporarily made less accessible using a semantic satiation procedure. In Studies 1 and 2, participants were slower to categorize facial behaviors depicting emotion (i.e., a face depicting anger) after an emotion word (e.g., "anger") was satiated. In Study 3, participants were less accurate to categorize facial behaviors depicting emotion after an emotion word was satiated. The implications of these findings for a linguistically relative view of emotion perception are discussed.
