Abstract

Shadowing and reading aloud both involve multiple complex cognitive processes, and both are considered effective methods for second-language learning. The working memory system, particularly the phonological loop, has been suggested to be involved in shadowing and reading aloud. The purpose of this study was to investigate the effects of a 4-week intensive adaptive training including shadowing and reading aloud of second language on working-memory capacity, regional gray matter volume (rGMV), and functional activation related to the n-back working-memory task in young adults. The results showed that compared with the training groups without speaking (listening to compressed speech and active control involving the second language), the training groups with speaking (shadowing and reading aloud) showed a tendency for greater test-retest increases in digit-span scores, and significantly greater test-retest decreases in N-back task reaction time (increase in working memory performance). Imaging analyses revealed compared with the active control group, shadowing group exhibited decreases in rGMV and brain activity during the working memory task (2-back task), in the left cerebellum and reading group exhibited decreases in them in the right anterior insula. These regions are parts of the phonological loop, suggesting the presence of training-induced neural plasticity in these neurocognitive mechanisms.

Two types of affect influence consumers' attention: incidental affect unrelated to a particular perception or judgment and integral affect directly related to the particular options under consideration. Although integral and incidental affect likely coexist on a regular basis, the claim that both concurrently guide consumers' attention has thus far received little attention. To fill this gap, the present study investigated the effects of the interplay of integral and incidental affect on the visual processing of food. Food labels play an essential role in attracting consumer attention. Food labels include sources of integral affect (e.g., food type, pictures), and consumers often view food labels under the influence of incidental affect (e.g., an unrelated anxiety-inducing message or personal experience). According to the appraisal tendency framework, incidental experiences of anxiety can enhance affective processing of food due to the uncertainty associated with anxiety. In our study, participants were first subjected to manipulation of an incidental emotion (anxiety, anger, or neutral). Then, they passively viewed food labels, including pictures and nutrient labels, for hedonic and healthy foods. Subject's eye movements were tracked during this stage of the study. Our results showed that the induction of incidental anxiety, but not anger or neutral feelings, led to greater visual attention on hedonic foods only. These findings shed light on the interplay between incidental and integral affect in consumer information processing, demonstrating that the co-occurrence of incidental anxiety and integral hedonic feelings enhance visual attention to food.
