L2 Reading Comprehension

A avaliação da compreensão leitora é um tema que tem motivado um número considerável de pesquisas. Muitos estudos mostram que as variáveis relativas às características dos leitores, tipos textuais, tarefa subsequente à compreensão e a língua do texto influenciam a maneira que os leitores abordam o material sendo lido. Neste artigo, é investigada a relação entre a habilidade do leitor de formular perguntas sobre um texto e a sua capacidade de memória de trabalho. Onze estudantes de pós-graduação em inglês como língua estrangeira/segunda língua/língua adicional realizaram um Teste de Alcance em Leitura e leram dois textos expositivos para formular uma pergunta ao final de cada parágrafo de cada um dos textos. Os resultados indicaram que, apesar de não haver uma correlação estatisticamente significativa entre as perguntas do tipo textual implícito e implícito no script, esses tipos de perguntas foram mais frequentemente formulados pelos participantes com maior capacidade de memória de trabalho, sugerindo que eles geraram maior número de inferências ao ler os textos.

Explanatory Mechanism

Previously it has been theorized that differential functioning of the locus coeruleus-norepinephrine (LC-NE) system affects people's ability to regulate arousal, which has impacts on cognitive abilities. In the present study, we investigated three potential mechanisms by which the LC-NE system can fail to regulate arousal appropriately: hypoarousal, hyperarousal, and dysregulation of arousal. Each of these three could potentially account for why arousal affects cognition. To test the contributions of these three mechanisms, the present study examined individual differences in working memory capacity (WMC) and the regulation of arousal using pupillometry. Participants completed multiple complex span and visual arrays change-detection measures of WMC. An eye-tracker recorded pupil diameter as participants completed the visual arrays tasks. We found rather mixed evidence for the three mechanisms. Arousal dysregulation correlated with lower visual arrays performance and more self-reported attentional lapses. However arousal regulation did not correlate with complex span performance. There was also some evidence for hypoarousal as an explanatory mechanism, as arousal correlated with attentional lapses. We discuss the implications of the results for theories regarding the role of arousal regulation in cognitive performance and individual differences in cognitive abilities.

Thought Probes

The present study examined individual differences in three cognitive abilities: attention control (AC), working memory capacity (WMC), and fluid intelligence (gF) as they relate the tendency to experience task-unrelated thoughts (TUTs) and the regulation of arousal. Cognitive abilities were measured with a battery of nine laboratory tasks, TUTs were measured via thought probes inserted into two tasks, and arousal regulation was measured via pupillometry. Recent theorizing (Robison & Unsworth, 2017a) suggests that one reason why some people experience relatively frequent TUTs and relatively poor cognitive performance - especially AC and WMC - is that they exhibit dysregulated arousal. Here, we examined how arousal regulation might predict both AC and WMC, but also higher-order cognitive abilities like gF. Further, we examine direct and indirect associations with these abilities via a mediating influence of TUT. Participants who reported more TUTs also tended to exhibit poorer AC, lower WMC, and lower gF. Arousal dysregulation correlated with more TUTs and lower AC. However there was no direct correlation between arousal regulation and WMC, nor between arousal regulation and gF. Rather, the associations between arousal regulation, WMC, and gF were indirect via TUT. We discuss the implications of the results in light of the arousal regulation theory of individual differences and directions for future research.

Object State

There remains limited consensus about whether individual differences in working memory capacity, influences mental representation updating during language comprehension. We argue that this question was not sufficiently examined in previous psycholinguistic studies due to methodological limitations. In the current study, we examine whether individual differences in keeping track of mental representations of objects during real-time language comprehension could be predicted by digit span, reading span, nonverbal intelligence, executive function, and visual working memory capacity. Data were collected from 26 adults who completed a battery of cognitive tests and an eye-tracking experiment using the visual world paradigm. In the eye-tracking experiment, participants listened to sentences that either indicated a substantial or a minimal change of state on the target object while viewing a visual scene depicting the target object in two conflicting states – being intact and being changed, along with two unrelated distractors. As expected, participants’ visual attention was directed to the visual depiction of the target object that matched the implied end state in the language. Importantly, we demonstrate that individual differences in cognitive abilities influence whether participants shift their attention to the language-mediated object-state representations.

Methodological Artifact

Updating is the executive function (EF) previously found to most strongly relate to higher cognitive abilities such as reasoning. However, this relationship could be a methodological artifact: Measures of other EFs (i.e., inhibition and shifting) usually isolate the contribution of EF, whereas updating is measured by overall accuracy in working memory (WM) tasks involving updating. This updating accuracy-score conflates updating-specific individual differences (e.g., removal of outdated information) with variance in WM maintenance. Re-analyzing data (N = 111) from von Bastian et al. (2016), we separated updating-specific variance from WM maintenance variance. Updating contributed only 15% to individual differences in performance in the updating tasks, and it correlated neither with reasoning nor with independent WM measures reflecting storage and processing or relational integration. In contrast, the WM maintenance component of the updating task correlated with both abilities. These findings challenge the view that updating contributes to variance in higher cognitive abilities.
