RESUMO
Three experiments investigated memory for semantic information with the goal of determining boundary conditions for the manifestation of semantic auditory distraction. Irrelevant speech disrupted the free recall of semantic category- exemplars to an equal degree regardless of whether the speech coincided with presentation or test phases of the task (Experiment 1), and this occurred regardless of whether it comprised random words or coherent sentences (Experiment 2). The effects of background speech were greater when the irrelevant speech was semantically related to the to-be-remembered material, but only when the irrelevant words were high in output dominance (Experiment 3). The implications of these findings in relation to the processing of task material and the processing of background speech are discussed.

Syntactical knowledge is vital for the comprehension and production of any language and this knowledge has also been shown to aid short-term memory (Perham, Marsh & Jones, 2009). Given that people with dyslexia are known to have difficulties in processing long-term serial order information which can be argued to underpin the use of syntactical rules, the following study explored a larger population-those who were high or low in reading abilities-and their ability to recall six-item word lists in both syntactically congruent and syntactically incongruent orders. Analyses revealed that the low reading group showed a syntactical congruency effect, but the high reading group did not. Results are discussed in terms of language and short-term memory.

An interference-by-content account of auditory distraction - in which the impairment to task performance derives from the similarity of what is being recalled and what is being ignored - was explored concerning mental arithmetic performance. Participants completed both a serial recall and a mental arithmetic task in the presence of quiet, office noise with speech (OS) and office noise without speech (ONS). Both tasks revealed that the two office noise condition's significantly impaired performance. That the ONS produced this deficit suggests that an interference-by-content account cannot explain impairment to mental arithmetic performance by background sound.

Laboratory research has long demonstrated the disruptive effects of background sound to task performance yet the real-world implications of such effects are less well known. We report two experiments that demonstrate the importance of the role of rehearsal to a novel call center-type task. In Experiment 1, performance of a novel train timetable task-in which participants identified four train journeys following presentation of train journey information-was disrupted by realistic office noise. However, in Experiment 2, when the need for rehearsal was reduced by presenting the information and the timetable at the same time, no disruption occurred . Results are discussed in terms of interference-by-process and interference-by-content approaches to short-term memory.

Public perceptions of pandemic viral threats and government policies can influence adherence to containment, delay, and mitigation policies such as physical distancing, hygienic practices, use of physical barriers, uptake of testing, contact tracing, and vaccination programs. The UK COVID-19 Public Experiences (COPE) study aims to identify determinants of health behaviour using the Capability, Opportunity, Motivation (COM-B) model using a longitudinal mixed-methods approach. Here, we provide a detailed description of the demographic and self-reported health characteristics of the COPE cohort at baseline assessment, an overview of data collected, and plans for follow-up of the cohort. The COPE baseline survey was completed by 11,113 UK adult residents (18+ years of age). Baseline data collection started on the 13th of March 2020 (10-days before the introduction of the first national COVID-19 lockdown in the UK) and finished on the 13th of April 2020. Participants were recruited via the HealthWise Wales (HWW) research registry and through social media snowballing and advertising (Facebook®, Twitter®, Instagram®). Participants were predominantly female (69%), over 50 years of age (68%), identified as white (98%), and were living with their partner (68%). A large proportion (67%) had a college/university level education, and half reported a pre-existing health condition (50%). Initial follow-up plans for the cohort included in-depth surveys at 3-months and 12-months after the first UK national lockdown to assess short and medium-term effects of the pandemic on health behaviour and subjective health and well-being. Additional consent will be sought from participants at follow-up for data linkage and surveys at 18 and 24-months after the initial UK national lockdown. A large non-random sample was recruited to the COPE cohort during the early stages of the COVID-19 pandemic, which will enable longitudinal analysis of the determinants of health behaviour and changes in subjective health and well-being over the course of the pandemic.

Tinnitus refers to the perception of sound in the absence of an external stimulus. This can be problematic and can lead to health problems in some sufferers, including effects on cognitive functions such as attention and memory. Although several studies have examined the effectiveness of tinnitus interventions, e.g., cognitive behavioral therapy and sound therapy, it is still unclear as to the overall quality and limitations of these studies and whether their results could be generalized. Clarification is also needed as to whether poor cognitive function will lead to a less favorable intervention outcome in tinnitus patients. The present systematic review was therefore designed to critically appraise and synthesize findings from randomized controlled trials (RCTs) of tinnitus intervention and its effects on cognition. The methodology followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Medline (PubMed), Embase, and PsycINFO were searched. Only RCTs that compared the effectiveness of a tinnitus intervention and a measure of cognitive function in adult participants with tinnitus were included. A total of 8 studies involving 610 participants tested using 11 cognitive function assessment tools (e.g., Stroop Color and Word Test and Visual Continuous Performance Task) and 5 tinnitus intervention outcome measurements (e.g., Tinnitus Handicap Inventory and Tinnitus Questionnaire) were included and analyzed. The outcomes of the review suggest that tinnitus intervention not only facilitates tinnitus management but also improves cognitive functions. It is likely that cognition and emotion play an important role in a patient's adjustment to tinnitus. Whether cognition can predict treatment outcomes is unclear due to insufficient evidence. Future research is needed using a standardized assessment protocol focusing on the effect of sound-based interventions on tinnitus severity and cognitive functions. Studies on whether cognitive function measurement can be used as a predictor for the effectiveness of tinnitus therapy are also needed.
RESUMO
Task-irrelevant speech impairs short-term serial recall appreciably. On the interference-by-process account, the processing of physical (i.e., precategorical) changes in speech yields order cues that conflict with the serial-ordering process deployed to perform the serial recall task. In this view, the postcategorical properties (e.g., phonology, meaning) of speech play no role. The present study reassessed the implications of recent demonstrations of auditory postcategorical distraction in serial recall that have been taken as support for an alternative, attentional-diversion, account of the irrelevant speech effect. Focusing on the disruptive effect of emotionally valent compared with neutral words on serial recall, we show that the distracter-valence effect is eliminated under conditions-high task-encoding load-thought to shield against attentional diversion whereas the general effect of speech (neutral words compared with quiet) remains unaffected (Experiment 1). Furthermore, the distracter-valence effect generalizes to a task that does not require the processing of serial order-the missing-item task-whereas the effect of speech per se is attenuated in this task (Experiment 2). We conclude that postcategorical auditory distraction phenomena in serial short-term memory (STM) are incidental: they are observable in such a setting but, unlike the acoustically driven irrelevant speech effect, are not integral to it. As such, the findings support a duplex-mechanism account over a unitary view of auditory distraction. (PsycINFO Database Record

BACKGROUND: Prohibiting the sale of alcohol to intoxicated patrons by licensees and their staff requires definitions of drunkenness. AIMS: To assess the relationship between blood alcohol concentration (BAC) and indicators used in field sobriety tests putatively associated with intoxication. DESIGN, PARTICIPANTS, SETTING, MATERIAL AND METHODS: A random sample of 314 female and 579 male city centre drinkers. Surveyors scored respondents' and non-respondents' gait, eyes and speech for signs of drunkenness as well as their drunkenness on a 10-point Likert scale. Breath analysis was used to determine respondents' BAC. FINDINGS: Combinations of slurred speech, staggering gait and glazed eyes significantly predicted levels of BAC with a staggering gait indicating highest levels of intoxication. CONCLUSIONS: Subjective ratings of drunkenness by trained observers corresponded with BAC. Transition BACs denoting observable behaviour change associated with intoxication have been identified. Observations of gait, combined with assessment of slurred speech should be the basis of estimates of drunkenness.

AIM: To assess the prevalence of alcohol misuse in the night-time economy. METHOD: A random sample of 893 people were interviewed and breathalysed in 24 repeated, cross-sectional surveys over the course of a year in the city centre streets of a European capital city between 11.00 pm and 3.00 am. RESULTS: Median blood alcohol concentration (BAC) in men was 0.13% (min = 0%, max = 0.33%) and in women was 0.09% (min = 0%, max = 0.27%)-which were below the threshold used to indicate 'at risk BAC' (0.15%; for men t = 9.32, P < 0.001 and for women t = 17.54, P < 0.001). Men provided higher BACs than women (t = 7.17, P < 0.001). The relationship between age and BAC for men described an inverted 'u', peaking at 29 years, but for women the relationship was positive and linear. BAC was inversely related to the ability to remember and report the evening's consumption (z = 4.76, P < 0.001). Reported consumption predicted only 12% (P < 0.001) of the variance in BAC for men and 10% (P < 0.001) for women. CONCLUSION: 'At risk' intoxication was apparent only in a minority of drinkers, who were mostly employed men in their late twenties, but a third of men and half of women had consumed more than the recommended daily limit. The probability for respondents to recall past consumption diminished as BAC increased suggesting self-report data are not suitable to assess consumption in heavy drinkers. Breath analysis surveys are valuable in understanding alcohol misuse in the night-time economy.

When solving mental arithmetic problems, one can easily be distracted by someone speaking in the background and this distraction is greater if the speech comprises numbers. We explored the basis of this disruption by asking participants to solve mental addition problems (e.g., "45 + 17 = ?") in three different conditions: background speech comprising numbers in ascending order (e.g., "61, 62, 63, 64, 65"), background speech comprising numbers in descending order (e.g., "65, 64, 63, 62, 61"), and quiet. Performance was best in quiet, worse in the descending numbers condition, and poorest in the ascending numbers condition. In view of these findings, we suggest that disruption arises as a by-product of preventing the primed, but inaccurate, candidate responses from assuming the control of action. Alternative explanations are also discussed.

Three experiments investigated the contrasting predictions of the evolutionary and decision-theoretic approaches to deontic reasoning. Two experiments embedded a hazard management (HM) rule in a social contract scenario that should lead to competition between innate modules. A 3rd experiment used a pure HM task. Threatening material was also introduced into the antecedent, p, of a deontic rule, if p then must q. According to the evolutionary approach, more HM responses (Cosmides & Tooby, 2000) are predicted when p is threatening, whereas decision theory predicts fewer. All 3 experiments were consistent with decision theory. Other theories are discussed, and it is concluded that they cannot account for the behavior observed in these experiments.
RESUMO
BACKGROUND: Cytologists must learn how to discriminate cells that might be visually very similar but have different neoplastic potential. The mechanism by which trainees learn this task is poorly researched and is the focus of the current investigation. Cognitive science offers a theoretical platform from which to design meaningful experiments that could lead to novel training strategies. METHODS: The interpretation of a cell image is a category-discrimination task, and the process by which discrimination improves with practice is called perceptual learning. The study authors operationalized this concept by training 150 naive observers on paired cell images without providing explicit tuition, employing cervical cytology as a model system. Six strategies were tested, which differed according to the diagnostic category and level of interpretive difficulty of each image. Participants were tested before and after training to determine the extent to which visual learning had occurred. RESULTS: Diagnostic accuracy improved for participants who were trained on normal/abnormal image pairs in which at least one member of the pair was "easy" to interpret (P < .05). Training was not effective when image pairs were drawn from the same diagnostic category or when both members of the pair were "difficult" to interpret (P > .05). CONCLUSIONS: Training on paired cell images without explicit tuition can be an efficient and effective means of visual learning in cytopathology, but only if care is taken to avoid image pairs from category boundaries. Training on same-category image pairs is ineffective. This study is a step toward the development of perceptual learning modules for cytopathology.

BACKGROUND: Acquisition of visual interpretation skills in cytopathology may involve 2 strategies. Analytic strategies require trainees to base their interpretive decisions on carefully considered and often exhaustive cytomorphologic feature lists, a process that can be time-consuming and inefficient. In contrast, nonanalytic pattern recognition strategies are rarely encouraged during training, even though this approach is characteristic of expert diagnostic behavior. This study evaluated the potential role of nonanalytic learning in cytopathology as an efficient alternative to analytic training. METHODS: Forty-nine cytology novice participants undertook an initial image interpretation test to obtain baseline diagnostic accuracy (test 1). Twenty-four participants subsequently received training in basic cervical cytomorphology and were given a list of cell features for future reference (the "analytic" group). The remaining 25 participants were simply shown 20 nonannotated paired images of normal and abnormal cervical cells (the "nonanalytic" group). Following a practice phase, both groups were retested (test 2). Prior to a final test (test 3), participants in both groups were instructed to adopt a combined analytic/nonanalytic diagnostic strategy. Diagnostic accuracy and response times were measured in each test. RESULTS: Diagnostic accuracy in both groups improved significantly between tests 1 and 2 (P<.001) but decreased between tests 2 and 3 (P<.05). Speed of response to test images was generally faster under nonanalytic than under analytic conditions. CONCLUSIONS: Nonanalytic reasoning in cytopathology image interpretation can be as accurate as traditional feature-based reasoning. Encouraging trainees to adopt pattern recognition strategies may help to expedite the acquisition of visual interpretation skills in cytopathology training programs, yet combining analytic and nonanalytic reasoning do not appear to be effective.

The extent to which familiar syntax supports short-term serial recall of visually presented six-item sequences was shown by the superior recall of lists in which item pairs appeared in the order of "adjective-noun" (items 1-2, 3-4, 5-6)--congruent with English syntax--compared to when the order of items within pairs was reversed. The findings complement other evidence suggesting that short-term memory is an assemblage of language processing and production processes more than it is a bespoke short-term memory storage system.

Most research on auditory distraction on task performance focuses on those features of the sound that determine a drop in efficiency, with scant regard for examining the processing properties inherent in the focal task. We report how one such property, retrieval strategy, can also influence the degree of disruption by background sound. Using a task that called for the retrieval of realistic train journey information, we showed that retrieval by categories of verbal sequences was not susceptible to disruption by office sound - 65-75 dB(A). However, versions of the task requiring either free or serial recall showed evidence of disruption, a pattern of results consistent with the changing-state account of the irrelevant sound effect, which highlights the key role of serial rehearsal in determining disruption.
