Gaze Following Is Modulated by Expectations Regarding Others' Action Goals.

ABSTRACT: Humans attend to social cues in order to understand and predict others' behavior. Facial expressions and gaze direction provide valuable information to infer others' mental states and intentions. The present study examined the mechanism of gaze following in the context of participants' expectations about successive action steps of an observed actor. We embedded a gaze-cueing manipulation within an action scenario consisting of a sequence of naturalistic photographs. Gaze-induced orienting of attention (gaze following) was analyzed with respect to whether the gaze behavior of the observed actor was in line or not with the action-related expectations of participants (i.e., whether the actor gazed at an object that was congruent or incongruent with an overarching action goal). In Experiment 1, participants followed the gaze of the observed agent, though the gaze-cueing effect was larger when the actor looked at an action-congruent object relative to an incongruent object. Experiment 2 examined whether the pattern of effects observed in Experiment 1 was due to covert, rather than overt, attentional orienting, by requiring participants to maintain eye fixation throughout the sequence of critical photographs (corroborated by monitoring eye movements). The essential pattern of results of Experiment 1 was replicated, with the gaze-cueing effect being completely eliminated when the observed agent gazed at an action-incongruent object. Thus, our findings show that covert gaze following can be modulated by expectations that humans hold regarding successive steps of the action performed by an observed agent.

Project description:Chronic obstructive pulmonary disease (COPD) is an illness that affects patients on multiple levels, both physically and psychologically. While there is a growing body of evidence for the efficacy of self-management among patients with COPD, little evidence is available on the optimal content and methods for delivering self-management support.The purpose of this study was to address gaps in the literature on self-management support by examining patients' responses to questions about goals, needs, and expectations regarding self-management using qualitative methods in a broadly representative sample of patients with moderate to severe COPD. By focusing on patients' perceptions of their needs, we hoped to guide development of cognitive-behavioural interventions for self-management support.Patients >45 years of age with a physician diagnosis of COPD were recruited as part of a larger randomised controlled trial designed to determine the effectiveness of a lifestyle behavioural intervention to increase physical activity. In-depth interviews were conducted at baseline data collection using 10 standardised open-ended questions tailored to examine factors relevant to self-management support including concerns, fears, learning needs, barriers, facilitators, and goals. All interviews were audio recorded and analysed using qualitative methods. Responses were coded by three raters into thematic categories.A sample of 47 interviews with patients of mean age 68.4 years, 53% male, 87% white were used in the analysis. The distribution of spirometric impairment based on percent predicted forced expiratory volume in 1 second (FEV1) was moderate (57.5%), severe (31.9%), and very severe (10.6%). In response to questions targeting needs and goals for care, three main themes (loss, fear, and desire for improved care) and seven associated sub-themes were identified. Because of breathlessness and fatigue as well as symptoms from conditions other than COPD, patients reported the loss of ability to participate in pleasurable and necessary activities of daily living and the desire to recover at least some of their functioning. They expressed problems with social isolation and uncertainty about their prognosis, as well as the hope to improve. In addition, fearful experiences associated with uncontrolled breathlessness and a wish for greater understanding and knowledge about treatment were major concerns.These qualitative results suggest that the content of self-management support for patients with COPD should focus on addressing patients' fears associated with the uncertainty, progression, and suffering of their disease, their expectations about overcoming or replacing losses, their needs for improved health literacy and their desire for improved care. These responses indicate areas where cognitive-behavioural intervention should focus in order to enhance patient self-efficacy, motivation, and behavioural change for improved self-management.
