Abstract
Goal neglect refers to when an aspect of task instructions is not utilised due to increased competition between goal representations, an attentional limit theoretically linked to working memory. In an attempt to alleviate goal neglect and to investigate the association between dorsolateral prefrontal cortex (DLPFC)-supported working memory and goal neglect, we used high-frequency repetitive transcranial magnetic stimulation to the left DLPFC whilst participants completed the letter-monitoring task, a measure of goal neglect, and an N3-back task, a working memory task known to be affected by rTMS of the left DLPFC, following 20 min of active and sham stimulation (run on separate days). We found increased accuracy on the N3-back task in addition to decreased goal neglect in the active compared to sham condition when controlling for age and fluid abilities (as assessed by matrix reasoning performance). Furthermore, analysis showed that active stimulation improvements on both the N3-back and letter-monitoring tasks were greater for those with higher fluid abilities. These findings provide support for the link between the DLPFC-support working memory and goal neglect. Increased performance on the N3-back task also supports the literature reporting a link between left DLPFC and verbal working memory. Results are evaluated in the context of potential use to alleviate symptoms of disorders related to goal neglect.

Abstract
OBJECTIVE Understanding the association between polygenic risk for ADHD and cognition throughout aging has not been widely studied. This study aimed to determine whether ADHD risk influences cognitive performance among individuals at both young-old and middle-old age. METHOD Participants from the Health and Retirement Study, a biennial survey of 20,000 Americans, were compared on executive function and delayed recall measures using regression analyses. RESULTS There was no significant effect of ADHD risk on memory at both age waves for African-ancestry (AA; n = 403) and European-ancestry (EA; n = 2,286). There was, however, a significant association between ADHD risk and performance on executive function for EA at middle-old age (p = .028), but not young-old age; no such association was observed for AA adults. CONCLUSION This finding suggests that ADHD risk may differentially influence cognition among older adults throughout the aging process, with important implications for future research.

Abstract
For many years, the functional role of the ventrolateral Pre-Frontal Cortex (PFC) was associated with executive functions, specifically in the context of non-affective cognitive processes. However, recent research has suggested that the ventrolateral PFC is also involved in the attention system. The Ben Shalom model of the functional organization of the prefrontal cortex (2019) posits that the ventrolateral PFC selects perceptual stimuli after integration by the adjacent ventromedial PFC. This article reviews the state-of-the-art findings to better understand the role of the ventrolateral PFC in the selection of perceptual information as grounded in the Ben Shalom model. Numerous studies have reported converging evidence for the selective role of this area. However, most argue that this perceptual selection takes place through the active updating of information values linked to goal-oriented actions. These studies thus view the ventrolateral PFC as part of a system that actively manipulates and changes processed information such as the working memory function, rather than being part of the attention system. In agreement with this view, this review suggests that this area is part of a complex and modular working memory system and illustrates with reference to Diamond's work on ADD. This working memory system is functionally and anatomically dispersed and includes the dorsolateral PFC, the ACC, the parietal cortex, the basal ganglia, and the cerebellum. Hence, future research should continue to explore the specific neurofunctional roles of these areas in working memory systems, and the connections between the different subareas in this complex array.

Abstract
Sluggish cognitive tempo (SCT) is of renewed interest. The relationship between SCT, IQ and achievement scores, and academic impairment ratings was investigated in 218 students with autism and 676 with ADHD (6-16 years) and 549 elementary school students (IQ ≥ 80). Mothers rated their children on the Pediatric Behavior Scale. Children in the autism/ADHD sample were also rated by teachers. Correlations between SCT and IQ and achievement scores (Verbal Comprehension, Perceptual Reasoning, Working Memory, Processing Speed, reading, math, and written expression) were all negative and were nonsignificant in the total autism/ADHD and elementary school samples, except for small correlations with Processing Speed and a timed math test. In contrast, mother and teacher SCT ratings were significantly related to mother and teacher academic and cognitive impairment ratings. SCT was not a significant predictor of achievement scores or academic impairment ratings in regression analysis. The strongest predictor of achievement test scores was IQ, and the strongest predictors of academic impairment were mother and teacher cognitive impairment ratings. Teacher inattention ratings predicted teacher academic impairment ratings in autism/ADHD and mother inattention ratings predicted mother academic impairment ratings in elementary school children. Therefore, inattention was more predictive of academic functioning than was SCT. Research shows a weak link between SCT and processing speed (contrary to what is implied by the term sluggish cognitive tempo), and other neuropsychological test scores are not consistently associated with SCT. It remains to be determined if neuropsychological tests can be developed to measure and further our understanding of SCT.

Abstract
Symptoms of inattention and hyperactivity/impulsivity, arranged along a continuum, are commonly associated with neuropsychological and academic deficits, even in the general population. The aim of this study is to analyze how Attention Deficit Hyperactivity Disorder (ADHD) symptoms are associated with the performance in neuropsychological and academic abilities (phonological processing, processing speed/automatic attention, executive functions, reading, and spelling) in school-age children. The sample consisted of 216 children from 3rd and 4th grades (M = 8.94 years old, SD =.71) from public elementary schools of two Brazilian capitals. Pearson correlation and Multiple Linear Regression analysis were performed. Inattention symptoms were the only predictors of performance in phonological processing (phoneme suppression and rapid automatized naming of letters), processing speed/automatic attention, executive functions, such as inhibitory control and cognitive flexibility, and reading fluency. Beta values ranged from .14 to .27, and the largest value was related to an inhibitory control task. Inattention, and not hyperactivity/impulsivity symptoms, seems to affect neuropsychological functions even in non-clinical diagnosed children. Contributions and future directions are discussed.

Abstract
Purpose Persons with aphasia (PWAs) have been shown to have impaired attention skills that may interfere with their ability to successfully participate in speech and language therapy. Fluctuations in attention can be detected using physiological measures such as electroencephalography (EEG), but these measures can be impractical for clinical use. The primary purpose of this study was to investigate observable behavioral signs of attention as a means of measuring within-session fluctuations in attention by comparing behavioral ratings to physiological changes. Other aims were to understand the relationship between observable behaviors and task performance and to determine whether syntactic complexity influences behavioral attention. Method Ten PWAs and 10 neurologically healthy adults underwent a sentence-reading task with 45 active and 45 passive sentences while video/audio and EEG data were recorded continuously. EEG data for each trial were classified into one of four levels of attention using a classification algorithm (Berka et al., 2004), and video/audio data were scored for accuracy and behavioral engagement by two trained speech-language pathologist students using a behavioral rating scale of inattention (Whyte et al., 1996). Results Results showed that behavioral engagement was significantly correlated with task performance, with higher engagement scores associated with fewer errors. Behavioral engagement did not differ based on syntactic complexity for either group, but PWAs had significantly lower behavioral engagement scores when they were in lower/distracted states of physiologically measured vigilant attention. Conclusion Behavioral observation may provide an alternative means of detecting clinically significant lapses in attention during aphasia therapy.

Abstract
OBJECTIVE It is crucial to clarify the structure of attention-deficit/hyperactivity disorder (ADHD) symptomatology in all age groups to determine how to best conceptualize this disorder across the lifespan. We tested the ADHD factor structure across adulthood and investigated independent associations with executive functions. METHOD Data from 645 adults aged 18-59 and 233 adults aged 60-85 were drawn from the Nathan Kline Institute Rockland Sample. Participants completed the Conners Adult ADHD Rating Scale and tests of executive functioning. Invariance of the ADHD factor structure was investigated using confirmatory factor analyses. Associations with cognition were explored using multiple linear regression. RESULTS Results confirmed a bifactor model with 3 specific factors (inattention, hyperactivity, and impulsivity). Factor loadings and item intercepts were invariant across ages. Levels of hyperactivity and impulsivity were lower in older adults. Inattentive symptoms in young adults were positively related to cognitive flexibility. In older adults, ADHD symptoms predicted poorer working memory. CONCLUSION ADHD symptoms manifest similarly across adulthood. The lack of robust associations between ADHD symptomatology and executive functions raises concerns about the usefulness of neuropsychological measures in diagnosing adult ADHD. These results support the validity of the ADHD concept in older adults but suggest a need for age-appropriate normative criteria.

Abstract
Inattention is a symptom of many clinical disorders including attention deficit hyperactivity disorder (ADHD) and is thought to be primarily related to limitations in working memory. In two studies, we investigated the implications of inattention for task switching performance. In study one, we measured task switching performance using predictable and unpredictable conditions in adults who self-rated inattention and other ADHD-related tendencies. Tasks required proactive control and reactive control, respectively, under both high and low working memory loads. Results revealed that inattentive, but not hyperactive/impulsive traits, predicted switch costs when switching was predictable and working memory load was high. None of the ADHD traits were related to unpredictable switch costs. Study two was designed to: (1) de-confound the role of proactive control and the need to keep track of task order in the predictable task switching paradigm; (2) investigate whether goal neglect, an impairment related to working memory, could explain the relationship between inattention and predictable task switching. Results revealed that neither predictability nor the need to keep track of the task order led to the association between switch costs and inattention, but instead it was the tendency for those high in inattention to neglect preparatory proactive control, especially when reactive control options were available.

Abstract
Constant improvement in hazard identification is key to personnel safety in the workplace. Semantic cues have been proposed to simplify knowledge retrieval for site inspectors in building construction. However, the effectiveness of this approach and its internal mechanisms remain unexamined. This study assesses the influence of semantic cues on inspection performance from the perspective of visual behavior during elevator installation. Our results indicate that semantic cues drive selective attention toward goal-relevant information more effectively compared with when no such cues are provided. Second, semantic cues can improve performance regarding goal-relevant hazards and not diminish performance for incidental hazards. Third, the improvement of working memory and inspection performance is more pronounced in experienced workers than in novices. This research highlights the influence of semantic cues for hazard identification on visual behavior and inspection performance, and can serve as a foundation for the allocation of resources to aid inspection during construction.

Abstract
Research has revealed a positive relationship between types of mind wandering and ADHD at clinical and subclinical levels. However, this work did not consider the relationship between mind wandering and the core symptoms of ADHD: inattention, hyperactivity and impulsivity. Given that the DMS-V attributes mind wandering to inattention only, and that only inattention is thought to result from impairment to the executive function linked to mind wandering, the present research sought to examine this relationship in 80 undiagnosed adults. Using both standard and easy versions of the Sustained Attention to Response Task (SART) we measured both spontaneous and deliberate mind wandering. We found that spontaneous mind wandering was related to self-reported inattentive traits when the task was cognitively more challenging (standard SART). However, hyperactive and impulsive traits were related to spontaneous mind wandering independent of task difficulty. The results suggest inattentive traits are not uniquely related to mind wandering; indeed, adults with hyperactive/impulsive traits were more likely to experience mind wandering, suggesting that mind wandering might not be useful diagnostic criteria for inattention.

Abstract
AIM To qualify cognitive impairment in adults with attention deficit hyperactivity disorder (ADHD) and evaluate the efficacy of memoplant in the treatment of this pathology. MATERIAL AND METHODS The authors present the results of the clinical, psychological and electroencephalographic examination of 40 patients with ADHD, aged from 18 to 45 years. All patients received memoplant in dose of 240 mg a day for 8 weeks. RESULTS AND CONCLUSION Adult patients with ADHD were characterized by both subjective and objective disorders of memory and attention. The results of the electroencephalographic study suggested the dysfunction of the frontal-thalamic regulatory system and the lack of non-specific activation of the reticular formation. After treatment, clinical improvement was observed in 24 patients (60.0%). Repeated psychological and neuropsychological examinations showed a reduction of inattention and improvement of memory performance.
