The degree to which people take advice, and the factors that influence advice-taking, are of broad interest to laypersons, professionals, and policy-makers. This meta-analysis on 346 effect sizes from 129 independent datasets (N = 17, 296) assessed the weight of advice in the judge-advisor system paradigm, as well as the influence of sample and task characteristics. Information about the advisor(s) that is suggestive of advice quality was the only unique predictor of the overall pooled weight of advice. Individuals adjusted estimates by 32%, 37%, and 48% in response to advisors described in ways that suggest low, neutral, or high quality advice, respectively. This indicates that the benefits of compromise and averaging may be lost if accurate advice is perceived to be low quality, or too much weight is given to inaccurate advice that is perceived to be high quality. When examining the three levels of perceived quality separately, advice-taking was greater for subjective and uncertain estimates, relative to objective estimates, when information about the advisor was neutral in terms of advice quality. Sample characteristics had no effect on advice-taking, thus providing no evidence that age, gender, or individualism influence the weight of advice. The findings contribute to current theoretical debates and provide direction for future research.

OBJECTIVES: Global suicide rates are highest among older adults, and especially older men, yet proximal predictors of suicidal ideation in older age remain poorly understood. This study tested the Interpersonal Theory of Suicide in older men and women by investigating whether perceived burdensomeness and thwarted belongingness and/or their interaction are proximal predictors of suicidal ideation before versus during the global COVID-19 pandemic. METHODS: The sample (N = 208) included healthy community-dwelling older Australian persons surveyed face-to-face pre-pandemic (n = 102), or online peri-pandemic (n = 106). Depression, social interaction, social satisfaction, thwarted belongingness, and perceived burdensomeness were assessed as predictors of suicidal ideation. RESULTS: Perceived burdensomeness was a more proximal predictor of suicidal ideation among older adults than depression or thwarted belongingness. Suicidal ideation and perceived burdensomeness were higher in men than women, but sex did not moderate the influence of perceived burdensomeness, thwarted belongingness or social satisfaction on suicidal desire. The interaction between perceived burdensomeness and thwarted belongingness predicted more additional variance in suicidal ideation in the older persons surveyed during the COVID-19 pandemic relative to those surveyed before the pandemic. CONCLUSION: Suicidal ideation among older persons peri-pandemic is discussed, and recommendations are made for age-specific suicide prevention strategies.

Punishment maximises the probability of our individual survival by reducing behaviours that cause us harm, and also sustains trust and fairness in groups essential for social cohesion. However, some individuals are more sensitive to punishment than others and these differences in punishment sensitivity have been linked to a variety of decision-making deficits and psychopathologies. The mechanisms for why individuals differ in punishment sensitivity are poorly understood, although recent studies of conditioned punishment in rodents highlight a key role for punishment contingency detection (Jean-Richard-Dit-Bressel et al., 2019). Here, we applied a novel ‘Planets and Pirates’ conditioned punishment task in humans, allowing us to identify the mechanisms for why individuals differ in their sensitivity to punishment. We show that punishment sensitivity is bimodally distributed in a large sample of normal participants. Sensitive and insensitive individuals equally liked reward and showed similar rates of reward-seeking. They also equally disliked punishment and did not differ in their valuation of cues that signalled punishment. However, sensitive and insensitive individuals differed profoundly in their capacity to detect and learn volitional control over aversive outcomes. Punishment insensitive individuals did not learn the instrumental contingencies, so they could not withhold behaviour that caused punishment and could not generate appropriately selective behaviours to prevent impending punishment. These differences in punishment sensitivity could not be explained by individual differences in behavioural inhibition, impulsivity, or anxiety. This bimodal punishment sensitivity and these deficits in instrumental contingency learning are identical to those dictating punishment sensitivity in non-human animals, suggesting that they are general properties of aversive learning and decision-making.

During the COVID-19 pandemic, older adults face high rates of social isolation compared to other age groups. This is due to the strict physical distancing rules applied to older adults as a result of their vulnerability to coronavirus. Social isolation is known to have negative impacts on the mental health of older adults as a result of loneliness. This includes increased risk of depression and suicidal ideation. This review explores the possible exacerbation of mental health issues among older adults due to social isolation experienced during the COVID-19 pandemic. We also present data demonstrating no difference in distress, and reduced loneliness, among older (N = 101, M age = 20.6 years; 51 female) Australians during early stages of the COVID-19 pandemic. With a globally aging population, resources are required to promote social engagement among older adults who may otherwise lead isolated lives. This review article highlights a need for studies examining the validity of online communication tools for ameliorating the ill effects of physical distancing among older adults.

Seeking advice from others may improve decision-making, particularly in older adults when cognitive decline can impair decision-making. This study measured the extent to which older adults rated the value of advice and used that advice in their decisions. Young (aged 18–37 years; n = 57) and older (aged 62–84 years; n = 56) adults completed a judge-advisor task incorporating advice from an expert and a novice. To capture interindividual differences in ratings of advice value and advice use (i.e., weight of advice), desire for autonomy, working memory, and fluid intelligence were assessed. Relative to young adults, older adults rated novice advice as being more valuable and were more likely to adjust their estimates based on expert and especially novice advice. Among older adults, poorer working memory and reduced preference for autonomous decision-making were associated with greater ratings of the value of novice advice, while better fluid intelligence was associated with increased ratings of the value of expert advice. Overall, older adults give more weight to advice and cognitive decline appears to compromise discrimination of the quality of that advice.

The aim of this qualitative study was to examine the nature of interruptions during medication administration. Focus groups were conducted with medical/surgical nurses (n = 15), critical care nurses (n = 13), and nurse managers/educators/specialists (n = 6). Most interruptions (78%) were predictable. Nurse-adopted strategies included blocking, engaging, mediating, multitasking, and preventing. Educational content was developed that relates behavioral strategies to respond to predictable and unpredictable interruptions.

© 2018 Objectives: We sought to evaluate the perceptions of nurses of an e-learning educational program to encourage the use of behavioural strategies—blocking, engaging, mediating, multitasking, and preventing—to reduce the negative effects of interruptions during medication administration. Design: A qualitative design was used to evaluate the impact of this e-learning educational intervention on nurses’ behaviour. Settings: Two wards (palliative care and aged care) from two different hospitals within a large local health service within Sydney Australia, were included in the study. These wards were also involved in a cluster randomised trial to test the effectiveness of the program. Participants: A purposive sample participated comprising nine registered and enrolled nurses certified to conduct medication administration, who had reviewed the educational modules. Methods: Two focus groups were conducted and these sessions were digitally recorded and transcribed verbatim. Thematic analysis identified seven themes. Results: The major themes identified included: perceptions of interruptions, accessing the program, content of the program, impact, maintaining good practice and facilitators and barriers to changing behaviour. Conclusions: The use of embedded authentic images of patient interruptions and management strategies increased some nurses’ perceived use of strategies to manage interruptions. Nurses varied in their perception as to whether they could change their behaviour with some describing change at the individual and ward team levels, while others described patient caseload and other health professionals as a barrier. The use of this innovative educational intervention is recommended for staff orientation, student nurses, medical officers and allied health staff. Further research is required in how this e-learning program can be used in combination with other effective interventions to reduce interruptions.

AIM: To explore interruptions during medication preparation and administration and their consequences. BACKGROUND: Although not all interruptions in nursing have a negative impact, interruptions during medication rounds have been associated with medication errors. METHOD: A non-participant observational study was undertaken of nurses conducting medication rounds. RESULTS: Fifty-six medication events (including 101 interruptions) were observed. Most medication events (99%) were interrupted, resulting in nurses stopping medication preparation or administration to address the interruption (mean 2.5 minutes). The mean number of interruptions was 1.79 (SD 1.04). Thirty-four percent of medication events had at least one procedural failure, while 3.6% resulted in a clinical error. CONCLUSIONS: Our study confirmed that interruptions occur frequently during medication preparation and administration, and these interruptions were associated with procedural failures and clinical errors. Nurses were the primary source of interruptions with interruptions often being unrelated to patient care. IMPLICATIONS FOR NURSING MANAGEMENT: This study has confirmed that interruptions are frequent and result in clinical errors and procedural failures, compromising patient safety. These interruptions contribute a substantial additional workload to medication tasks. Various interventions should be implemented to reduce non-patient-related interruptions. Medication systems and procedures are advocated, that reduce the need for joint double-checking of medications, indirectly avoiding interruptions.

Single-cue delay eyeblink conditioning is presented as a prototypical example of automatic, nonsymbolic learning that is carried out by subcortical circuits. However, it has been difficult to assess the role of cognition in single-cue conditioning because participants become aware of the simple stimulus contingency so quickly. In this experiment (n 166), we masked the contingency to reduce awareness. We observed a strong relationship between contingency awareness and conditioned responding, with both trace and delay procedures. This finding suggests that explicit associative knowledge and anticipatory behavior are regulated by a coordinated system rather than by functionally and neurally distinct systems.© 2013, Published by Cold Spring Harbor Laboratory Press.

Squire and colleagues have proposed that trace and delay eyeblink conditioning are fundamentally different kinds of learning: trace conditioning requires acquisition of a conscious declarative memory for the stimulus contingencies whereas delay conditioning does not. Declarative memory in trace conditioning is thought to generate conditioned responding through the activation of a conscious expectancy for when the unconditioned stimulus (US) is going to occur. Perruchet (1985) has previously shown that in a 50% partial reinforcement design it is possible to dissociate single cue delay eyeblink conditioning from conscious expectancy for the US by examining performance over runs of reinforced and nonreinforced trials. Clark, Manns, and Squire (2001) claim that this dissociation does not occur in trace eyeblink conditioning. In the present experiment we examined the Perruchet effect for short, moderate, and long trace intervals (600, 1000, and 1400 ms) and for the equivalent interstimulus intervals (ISIs) in a delay conditioning procedure. We found evidence for a dissociation of eyeblink CRs and US expectancy over runs regardless of whether there was a delay or a trace arrangement of cues. The reasons for the Perruchet effect are still unclear, but the present data suggest that it does not depend on a separate nondeclarative system of the type proposed by Squire and colleagues.

This study aimed to assess the potential association between age-related prefrontal brain changes and slot machine gambling, an activity that has become increasingly popular among older adults. Functional magnetic resonance imaging was used to assess healthy older and younger adults whilst playing a slot machine. Results revealed that the older group over-recruited several bilateral and contralateral brain structures relative to the younger group. Specifically, older adults exhibited increased neural activation in the superior prefrontal cortex and left orbitofrontal cortex, indicating greater reliance on these structures. These results suggest a compensatory mechanism, by which older adults recruit a greater number of neural networks from both hemispheres to complete the same gambling task as their younger peers. The broader implications of these findings are discussed in relation to theories of neurocognitive and degenerative change that occurs in late adulthood. © 2012 McCarrey et al.
