RESUMO
OBJECTIVES: Older adults are often less accurate than younger counterparts at identifying emotions such as anger, sadness, and fear from faces. They also look less at the eyes and more at the mouth during emotion perception. The current studies advance understanding of the nature of these age effects on emotional processing. METHODS: Younger and older participants identified emotions from pictures of eyes or mouths (Experiment 1) and incongruent mouth-eyes emotion combinations (Experiment 2). In Experiment 3, participants categorized emotions from pictures in which face masks covered the mouth region. RESULTS: Older adults were worse than young at identifying anger and sadness from eyes, but better at identifying the same emotions from the mouth region (Experiment 1) and they were more likely than young to use information from the mouth to classify anger, fear, and disgust (Experiment 2). In Experiment 3, face masks impaired perception of anger, sadness, and fear more for older compared to younger adults. DISCUSSION: These studies indicate that older people are more able than young to interpret emotional information from the mouth, they are more biased to use information from the mouth, and suffer more difficulty in emotion perception when the mouth is covered with a face mask. This has implications for social communication in different age groups.

There is increasing awareness of the impact functional conditions have on the National Health Service (NHS). Less is known about the resources used to manage these conditions. This retrospective quantitative audit aims to determine the demographic and healthcare utilisation of functional abdominal pain patients presenting to the hospital. The most frequent hospital attenders with non-specific abdominal pain in NHS Grampian, 2018-2019, were assessed (n=144). Adult patients meeting the ROME II diagnostic criteria for functional abdominal pain diagnosis were included (n=33). Data were retrospectively collected manually from electronic medical records. Of 33 patients, 93.9% were female, with a mean age of 31.2 years. Each had accessed a mean of 11.5 specialist services, with 69.7% being referred to mental health services; 9.1% had completed treatment. Each patient had a median 4 (range 1-26) emergency/unscheduled presentations to hospital and median 2 (range 0-13) admissions for functional abdominal pain during the study period, with a total of 247 nights spent in hospital by this patient cohort for functional abdominal pain alone. The estimated total cost for these hospital admissions was £593,786.00. Extensive secondary-care input is currently required for patients with functional abdominal pain at a significant cost. Patients are re-presenting to the hospital frequently, which suggests that current management is not effective.
RESUMO
There is limited evidence of the effectiveness of non-surgical interventions for severe obesity. Our aim was to evaluate a group intervention delivered by a National Health Service (NHS) specialist weight management service to contribute to the evidence base and inform the development of future services. Participants in this prospective cohort study were patients attending NHS Grampian Specialist Weight Management Services. The intervention was an interactive 12-session group programme based on evidence-based psychological model, with combined dietetic and psychological knowledge and support provided. The primary outcome was mean weight change at the end of the intervention and for 12-mo follow-up (including programme completers, baseline observation carried forward [BOCF], last observation carried forward). Secondary outcome measures included mood, anxiety, binge eating and quality of life. A total of 166 patients accepted a place on the group programme, mean body mass index was 48.9 kg/m2 . Mean weight loss at 6 mo was 5.6 kg and 35.2% of those who completed the group (n = 88) lost ≥5%. Using BOCF, 18.7% lost ≥5% at 6 mo. Those who remained in the programme maintained their weight loss 12 and 18 mo after the start of the intervention. Significant improvements were also found in psychological variables, including reduced depression, anxiety, binge eating and improved emotion regulation. This real-world evaluation of an NHS intervention for patients with severe obesity suggests that individuals who engage achieve a moderate weight loss, which most maintain a year later, although further research is needed to strengthen this conclusion.

People with Alzheimer's disease (AD) show problems with social processing in tasks which require the understanding of others' mental states. However traditional social processing tasks are cognitively complex, which may influence the effects of AD. Less is known about how AD influences more basic aspects of social perception, such as the ability to decode eye gaze direction or follow the gaze of another. The current research assessed whether those with AD showed difficulty in both explicitly decoding subtle manipulations of gaze direction (Study 1), and reflexively following another's eye gaze (Study 2). Those with AD were more impaired than a matched control group when making explicit discrimination distinctions between direct and averted gaze. In contrast people with Alzheimer's disease performed comparably to a control group when following gaze. This pattern indicates that more automatic aspects of social perception such as gaze following are unaffected by AD. In contrast, more controlled processes such as deciding whether someone is looking towards you are impaired in AD. This has implications for socially engaging with other people and interpreting their focus of interest.

BACKGROUND: Eye-gaze following is a fundamental social skill, facilitating communication. The present series of studies explored adult age-related differences in this key social-cognitive ability. METHOD: In Study 1 younger and older adult participants completed a cueing task in which eye-gaze cues were predictive or non-predictive of target location. Another eye-gaze cueing task, assessing the influence of congruent and incongruent eye-gaze cues relative to trials which provided no cue to target location, was administered in Study 2. Finally, in Study 3 the eye-gaze cue was replaced by an arrow. RESULTS: In Study 1 older adults showed less evidence of gaze following than younger participants when required to strategically follow predictive eye-gaze cues and when making automatic shifts of attention to non-predictive eye-gaze cues. Findings from Study 2 suggested that, unlike younger adults, older participants showed no facilitation effect and thus did not follow congruent eye-gaze cues. They also had significantly weaker attentional costs than their younger counterparts. These age-related differences were not found in the non-social arrow cueing task. DISCUSSION: Taken together these findings suggest older adults do not use eye-gaze cues to engage in joint attention, and have specific social difficulties decoding critical information from the eye region.

The present study explored own-age biases in deception detection, investigating whether individuals were more likely to trust those in their own-age group. Younger and older participants were asked to detect deceit from videos of younger and older speakers, rating their confidence in each decision. Older participants showed an own-age bias: they were more likely to think that deceptive speakers of their own age, relative to younger speakers, were telling the truth. Older participants were also more confident in their judgements of own-age, relative to other-age, speakers. There were no own-age biases for younger participants. In a subsequent (apparently unrelated) task, participants were asked to rate the trustworthiness of the speakers. Both age groups of participants trusted younger speakers who had previously told the truth more compared to those who had lied. This effect was not found for older speakers. These findings are considered in relation to the in-group/out-group model of social cognition and common stereotypical beliefs held about younger and older adults.

UNLABELLED: BACKGROUND/STUDY CONTEXT: Social perception may be influenced by the extent to which individuals focus on global, rather than local, detail-based, processing of information about others. Here the authors investigated whether global processing biases relate to successful detection of actions and emotions from point-light biological motion (BM) stimuli. Also explored is whether age differences in BM perception and global-local processing biases are related. METHODS: One hundred and twenty-seven participants (aged 18 to 86) completed tasks assessing BM perception and global-local processing. RESULTS: Successful decoding of actions and emotions from BM stimuli was correlated with global processing bias. Older adults performed more poorly on BM decoding and had a local processing bias. However, age differences in global-local processing could not fully explain differences in decoding actions or emotions from point-light displays. CONCLUSION: Therefore, although there was an association between age, perceptual processing bias, and detection of BM, other factors must be important in explaining age-related change in social perception.

Older adults often perform poorly on Theory of Mind (ToM) tests that require understanding of others' beliefs and intentions. The course and specificity of age changes in belief reasoning across the adult lifespan is unclear, as is the cause of the age effects. Cognitive and neuropsychological models predict that two types of processing might influence age differences in belief reasoning: executive functioning and social cue detection. In the current study we assessed 129 adults aged between 18 and 86 on novel measures of ToM (video clips and verbal vignettes), which manipulated whether true or false belief reasoning was required. On both video and verbal tasks, older adults (aged 65-88) had specific impairments in false belief reasoning, but showed no such problem in performing true belief tasks. Middle-aged adults (aged 40-64) generally performed as well as the younger adults (aged 18-39). Difficulties in updating information in working memory (but not inhibitory problems) partially mediated the age differences in false belief reasoning. Also, the ability to decode biological motion, indexing social cue detection, partially mediated age-related variance in the ability to interpret false beliefs. These results indicate that age differences in decoding social cues and updating information in memory may be important influences on the specific problems encountered when reasoning about false beliefs in old age.
