Asymmetric interference in implicit memory: effects of study-test awareness and stimulus order

This study examined the extent to which fragment completion performance is susceptible to the effects of two different forms of interference (proactive and retroactive) and whether any of these effects depend on participants' awareness of the relationship between study and test. Unaware participants were found to be susceptible to proactive but not retroactive interference. Aware participants did not show evidence of susceptibility to either form of interference. These results contribute to the debate about whether implicit memory is immune to interference effects by demarcating the limits of such an immunity.     

Connecting the dots: children's use of a systematic figure to facilitate mapping and search

Organizing locations into a systematic figure was predicted to facilitate children's use of spatial relations in a mapping task. In Study 1, 3-, 4-, and 5-year-olds used a map to find a sticker hidden under 1 of 27 locations. The search locations formed a systematic figure, the outline of a dog. Half of the children were shown that the locations formed a dog. Seeing the dog pattern facilitated the performance of 5-year-olds but not that of the younger children. Study 2 indicated that children had to see a systematic figure to gain an advantage; adding lines to an unsystematic figure did not convey an advantage. Study 3 indicated that a verbal label alone could not convey an advantage. Study 4 revealed that seeing the dog pattern could also facilitate performance when the map was rotated relative to the represented space. The importance of organizing spatial information to facilitate relational thinking and mapping is discussed.     

How Reliably Do Eye Parameters Indicate Internal Versus External Attentional Focus?

Eye behavior is increasingly used as an indicator of internal versus external focus of attention both in research and application. However, available findings are partly inconsistent, which might be attributed to the different nature of the employed types of internal and external cognition tasks. The present study, therefore, investigated how consistently different eye parameters respond to internal versus external attentional focus across three task modalities: numerical, verbal, and visuo-spatial. Three eye parameters robustly differentiated between internal and external attentional focus across all tasks. Blinks, pupil diameter variance, and fixation disparity variance were consistently increased during internally directed attention. We also observed substantial attentional focus effects on other parameters (pupil diameter, fixation disparity, saccades, and microsaccades), but they were moderated by task type. Single-trial analysis of our data using machine learning techniques further confirmed our results: Classifying the focus of attention by means of eye tracking works well across participants, but generalizing across tasks proves to be challenging. Based on the effects of task type on eye parameters, we discuss what eye parameters are best suited as indicators of internal versus external attentional focus in different settings.     

Investigating the effects of a virtual reality-based stress management programme on inpatients with mental disorders: A pilot randomised controlled trial

This study aimed to examine the effects and feasibility of a virtual screen-based stress management programme (V-DESSERTS) on inpatients with mental disorders. A single-blinded, pilot randomised controlled trial was conducted in a tertiary hospital in Singapore. Convenience sampling was used and participants were randomised into either the intervention group or the waitlisted control group (WL). The intervention group received individual-based, twice-daily sessions of the programme. Each session comprised education and virtual screen-based relaxation practice. Data were collected through self-reported questionnaires and physiological measures. The intervention group showed a significant increase in perceived relaxation and knowledge in comparison with the WL group. However, inconclusive results were observed on subjective and objective stress. The findings in this study indicated that the V-DESSERTS programme is feasible to be implemented for patients with schizophrenia, depression and bipolar disorders.     

Wearable Activity Technology And Action-Planning (WATAAP) to promote physical activity in cancer survivors: Randomised controlled trial protocol

Background/Objective: Colorectal and gynecologic cancer survivors are at cardiovascular risk due to comorbidities and sedentary behaviour, warranting a feasible intervention to increase physical activity. The Health Action Process Approach (HAPA) is a promising theoretical framework for health behaviour change, and wearable physical activity trackers offer a novel means of self-monitoring physical activity for cancer survivors. Method: Sixty-eight survivors of colorectal and gynecologic cancer will be randomised into 12-week intervention and control groups. Intervention group participants will receive: a Fitbit Alta? to monitor physical activity, HAPA-based group sessions, booklet, and support phone-call. Participants in the control group will only receive the HAPA-based booklet. Physical activity (using accelerometers), blood pressure, BMI, and HAPA constructs will be assessed at baseline, 12-weeks (post-intervention) and 24-weeks (follow-up). Data analysis will use the Group x Time interaction from a General Linear Mixed Model analysis. Conclusions: Physical activity interventions that are acceptable and have robust theoretical underpinnings show promise for improving the health of cancer survivors.     

Asymmetric goal contagion: Social power attenuates goal contagion among strangers

Goal contagion is an important interpersonal process. As people spontaneously infer and adopt others' goals, goals can be said to “flow” among individuals. We find that possessing power attenuates goal contagion, especially for high perspective takers. In a pilot study (N = 157), we first affirmed the interpersonal nature of goal contagion by establishing that high (vs. low) perspective takers were more likely to engage in goal contagion. We then tested the moderating role of power in two studies. In both neutral (Study 1, N = 179) and low power (Study 2, N = 304) conditions, we replicated the pattern in the pilot study. In the high power conditions, however, neither low nor high perspective takers engaged in goal contagion. Our findings suggest that goals flow asymmetrically from the powerful to the powerless, which may constitute an important means through which power hierarchy and group cohesion are maintained.     

Sexual dimorphism and attractiveness in Asian and White faces

Marriages between White men and Asian women are over twice as frequent as those between White women and Asian men. Recent research has proposed that this imbalance may be explained by the finding that, on average, White men are perceived as more attractive than Asian men, and Asian women are perceived as more attractive than White women, possibly because Asian faces are perceived as more feminine than White faces. Here, we explore whether Asian faces are perceived as more feminine than White faces. Thirty-five Malaysian Chinese (20 male) and 30 Australian White (12 male) participants manipulated 100 face photographs (50 Asian; 50 White; half male) on a masculinity/femininity axis to optimize attractive appearance. As predicted, White women’s faces were increased more in femininity than Asian women’s faces, and White men’s faces were feminized more than Asian men’s faces to optimize attractiveness. These findings suggest that White faces are perceived as more masculine than Asian faces.     

Parent-Child Interaction Therapy and ADHD: A Case Study With a Hearing Child of a Deaf Father and a Hearing Mother

Parent-Child Interaction Therapy (PCIT) has demonstrated promising evidence in its implementation with deaf and hard-of-hearing (DHH) families. This case study presents the implementation of PCIT with a hearing mother, a deaf father, and their 7-year-old hearing son with Attention-Deficit/Hyperactivity Disorder (ADHD) and oppositional behaviors, using the assistance of certified interpreters. Results documented improvement in child behavior, parenting skills and stress, and parent-child communication. Notably, paternal ratings showed greater improvement across these outcomes than maternal ratings. Overall, PCIT continues to demonstrate its effectiveness as a treatment option for DHH families with children with challenging behaviors. The limitations and implications are discussed.     

Are individual differences in masked repetition and semantic priming reliable?

Despite the robustness of semantic priming (e.g., cat–DOG), the test-retest and internal reliabilities of semantic priming effects within individuals are surprisingly low. In contrast, repetition priming (e.g., dog–DOG) appears to be far more reliable across a range of conditions. While Stolz and colleagues attribute the low reliability in semantic priming to uncoordinated automatic processes in semantic memory, their use of unmasked priming paradigms makes it difficult to fully rule out the influence of strategic processes. In the present study, we explored the reliability of semantic and repetition priming when primes were heavily masked and cannot be consciously processed. We found that masked repetition, but not semantic, priming effects showed some degree of reliability. Interestingly, skilled lexical processors (as reflected by vocabulary knowledge and spelling ability) also produced larger masked repetition priming effects.
