Description
Individual differences in working memory capacity partly arise from variability in attention control, a process influenced by negative emotional content. Thus, individual differences in working memory capacity should be predictive of differences in the ability to regulate attention in emotional contexts. To address this hypothesis, a complex-span working memory task (symmetry span) was modified so that negative arousing images or neutral images subtended the background during the encoding phase. Across three experiments, negative arousing images impaired working memory encoding relative to neutral images, resulting in impoverished symmetry span scores. Additionally, in Experiment 3, both negative and arousing images captured attention and led to increased hit rates in a subsequent recognition task. Contrary to the primary hypothesis, individual differences in working memory capacity derived from three complex span tasks failed to moderate the effect of negative arousing images on working memory encoding across two large scale studies. Implications for theories of working memory and attention control in emotional contexts will be discussed.

Description
The levels of student-perceived anxiety and attention in the Italian language classroom were evaluated. The central evaluation focused on the differences between how students experience anxiety and attention between Italian language and non-language courses. First-year Italian language students were surveyed using a self-report measure to identify individual levels of anxiety and attention during Elementary Italian I (ITA 101) courses compared to their experiences in non-language 100-level courses. A total of 65 responses were collected from the ITA 101 students of four different professors at Arizona State University. It was hypothesized that students experience more anxiety and pay greater attention during language courses in comparison to non-language courses. However, the differences between how students experienced both attention and anxiety across language and non-language course types was not significant. Using the demographic and supplementary questions from the survey, the differing experiences of students with or without previous language experience were examined. The results suggest a significant relationship between students with language experience and how they experience attention in Italian language courses. Additionally, statistical analysis suggests that students experience anxiety differently in Italian language courses dependent on previous second language experience. Implications for language course prerequisites were identified and suggest that it is beneficial for students to have prior second language experience before enrolling in Italian courses. Suggestions for future research were made, including a suggestion for additional research to explore how anxiety and attention may differ in higher-level language courses in addition to a suggestion for creating a more reliable and valid survey for testing classroom anxiety and attention levels.

Description
The need to fully understand the possible consequences of young-adult cannabis use has become increasingly critical as a result of major cannabis policy changes. The purpose of this study was to determine if young-adult users exhibit cognitive deficits on laboratory-based tests and memory and attention deficits in everyday life. Participants were 152 students from a large U.S. university enrolled in introductory psychology courses and the top and bottom 10% of the 12-item Yale University PRIME Screening Test for psychotic-like experiences. Participants were asked about their cannabis use and were given six cognitive tests spanning executive function and memory. To test functional impairment in memory and attention, participants were asked to nominate informants (people who knew them well) and these rated the participants on an attention problems scale of four items and a memory problems scale of three items. Results showed that individuals who used cannabis more frequently were rated as having more attention and memory problems and that, consistent with prior research, more frequent cannabis use was associated with worse memory test performance, though the association was not present between frequency of use and executive function test performance. Additionally, it was found that informant-reported attention problems were associated with poorer performance on two of the executive function cognitive tests. The present findings suggest that individuals who use cannabis more frequently experience noticeable memory and attention problems in everyday life, despite the lack of significant correlation between this functional impairment and cognitive test performance. Informant reports, therefore, may be useful in future research for understanding or predicting cognitive impairment in young adults.

Description
Previous research has yielded an equivocal answer as to whether speaking aloud while performing intelligence tasks improves, impairs, or has no effect on performance. Some studies show that it impairs performance while others show it aids performance. In the studies in which speaking aloud has been shown to help, only children and older adults benefitted. The present study investigated whether college-aged students benefit from speaking aloud while performing a fluid intelligence test. Subjects performed a battery of working memory and intelligence tasks silently. Once they had completed each task, the participants took them again, though this time they spoke aloud while completing the tests. Results showed that subjects did insignificantly worse on the working memory tests when speaking aloud. However, subjects performed significantly better on the measures of fluid intelligence while speaking aloud as opposed to doing them silently. At an individual differences level, low working memory capacity participants benefited more from speaking aloud than the high working memory ones. Finally, we found a positive correlation between working memory scores and fluid intelligence scores, offering further evidence that the two constructs are related, yet different.

Description
Pain has been found in previous research to have a noticeable effect on people’s ability to perform creative tasks. While limited studies in this field exist, most of this work has focused on convergent thinking through the use of compound remote associates tasks (CRAT). In order to investigate how acute pain might affect divergent creative cognition involving a wider answer space, the current study was conducted using an alternate uses task (AUT) during an algometer-based pain intervention. It was found that acute pain did not have a significant effect on accuracy in the CRAT nor on problem solving abilities in the AUT but notably, participants in the pain condition were more likely to say that they solved problems in the CRAT through insight rather than by an analytical approach. This work demonstrates the need for more research in this field to better understand the relationship between creative cognition and pain.

Description
Working memory capacity and fluid intelligence are important predictors of performance in educational settings. Thus, understanding the processes underlying the relation between working memory capacity and fluid intelligence is important. Three large scale individual differences experiments were conducted to determine the mechanisms underlying the relation between working memory capacity and fluid intelligence. Experiments 1 and 2 were designed to assess whether individual differences in strategic behavior contribute to the variance shared between working memory capacity and fluid intelligence. In Experiment 3, competing theories for describing the underlying processes (cognitive vs. strategy) were evaluated in a comprehensive examination of potential underlying mechanisms. These data help inform existing theories about the mechanisms underlying the relation between WMC and gF. However, these data also indicate that the current theoretical model of the shared variance between WMC and gF would need to be revised to account for the data in Experiment 3. Possible sources of misfit are considered in the discussion along with a consideration of the theoretical implications of observing those relations in the Experiment 3 data.

Description
The present study researched the systematic biases in working memory and how items interact with each other in working memory. The first goal of the study was to assess whether working memory representations of one another or systematically interact. This was tested by the repulsion bias in the representations. The second goal was to test whether the interaction is modulated by attentional priority. Attended items exhibited a weaker repulsion bias indicating that attention helped to protect the representation from the impact of the un-attended item.The average mean error for the unattended item was 3.68º while for the attended item it was 2.19º. These results are consistent with the hypothesis that items in working memory systematically interact with each other and further suggests that the main theories in working memory that do not assume interactions need to be updated.

Description
In this study, the role of attention in facial expression processing is investigated, especially as it relates to fearful facial expressions compared to happy facial expressions. Facial fear processing plays a critical role in human social interactions and survival, and this has previously been studied mainly in animal models. This study, however, was accomplished with the presentation of images of actors with happy and fearful facial expressions in three spatial frequency formats, as it is hypothesized that images at different spatial frequencies may be processed via different pathways. These images were presented to human participants in two experiments. In Experiment I, facial expression was task-relevant as participants were asked to discriminate between “happy” and “fear” expressions with reaction time (measured in seconds) and accuracy recorded. In Experiment II, facial expression was task-irrelevant, as participants were asked simply to discriminate between photographs of males and females, again with reaction time and accuracy recorded. Overall, the results comparing happy and fearful facial expressions in Experiment I were not significant. The results comparing happy and fearful facial expressions in Experiment II exhibited similar insignificant results except for accuracy in certain spatial frequencies, which were found to be significant. These results suggest that fearful facial expressions are processed more accurately than happy facial expressions when attention is focused on other variables in the image rather than when attention is focused on the facial expressions themselves.

Description
Purpose: Children with attention-deficit/hyperactivity disorder (ADHD) have been found to have central executive deficits in working memory as well as less academic success than children with typical development. The purpose of this study was to determine which components of central executive function were most closely related to parental rating scores of attention.
Method: Two hundred twenty three 2nd graders with typical development, dyslexia, developmental language disorder (DLD), or dyslexia/DLD completed three central executive tasks from the Comprehensive Assessment Battery for Children–Working Memory (Gray, Alt, Hogan, Green, & Cowan, n.d.). Parents of the children completed the ADHD Rating Scale-IV: Home Version for their child. None of the participants had been diagnosed with ADD/ADHD
Results: When diagnostic group performance was compared we found significant differences on each central executive task. When ADHD group performance was compared we found a significant between-group performance only on the n-back visual task with the high-risk group scoring lower than the other two groups. ADHD rating scores predicted a significant amount of variance for each central executive task, but percentages were small (3%-6%).
Discussion: Working memory is known to be related to attention control. Stronger attentional control is associated with a higher working memory performance. Our study showed that children most at risk for ADD/ADHD based on parent ratings scored lowest on the visuospatial task, likely because rehearsal of visuospatial information is not possible so relies more heavily on attention. This study is a step toward considering how attention affects working memory performance so that both can be considered when designing instruction and interventions.

Description
The locus coeruleus-norepinephrine system (LC-NE) has been argued to play a vital role in task engagement and attention control by the adaptive gain theory (Aston-Jones & Cohen, 2005). One of the central claims of this theory is that tonic LC activity exhibits a quadratic relationship with task performance. Pupil dynamics have been correlated to LC-NE activity via primate intracranial recordings in ways that provide evidence for the adaptive gain theory. Due to the small size and location of the LC, less is known about LC functioning in humans, leading to a desire to find valid, noninvasive psychophysiological proxies to study this structure. In this paper we performed a replication of Murphy, Robertson, Balsters, & O’Connell (2011) to gather evidence on whether pupil fluctuations and the P3 event-related potential are viable markers for measuring tonic and phasic LC-NE activity in humans. A sample of 33 subjects from the Arizona State University human subjects pool provided usable electroencephalogram and pupillometry data collected during an auditory oddball task. Our analyses largely correspond with those found in Murphy et al. (2011) showing some evidence that pupillometry and P3 can be utilized when studying the LC. Moving forward we will reproduce the full set of analyses from Murphy et al. (2011) with our dataset.
