Agency and ownership are independent components of 'sensing the self' in the auditory-verbal domain

'Sensing the self' relies on the ability to distinguish self-generated from external stimuli. It requires functioning mechanisms to establish feelings of agency and ownership. Agency is defined causally, where the subjects action is followed by an effect. Ownership is defined by the features of the effect, independent from the action. In our study, we manipulated these qualities separately. 13 right-handed healthy individuals performed the experiment while 76-channel EEG was recorded. Stimuli consisted of visually presented words, read aloud by the subject. The experiment consisted of six conditions: (a) subjects saw a word, read it aloud, heard it in their own voice; (b) like a, but the word was heard in an unfamiliar voice; (c) subject heard a word in his/her own voice without speaking; (d) like c, but the word was heard in an unfamiliar voice; (e) like a, but subjects heard the word with a delay; (f) subjects read without hearing. ERPs and difference maps were computed for all conditions. Effects were analysed topographically. The N100 (86-172 ms) displayed significant main effects of agency and ownership. The topographies of the two effects shared little common variance, suggesting independent effects. Later effects (174-400 ms) of agency and ownership were topographically similar, suggesting common mechanisms. Replicating earlier studies, significant N100 suppression was observed, with a topography resembling the agency effect. 'Sensing the self' appears to recruit from at least two very distinct processes: an agency assessment that represents causality and an ownership assessment that compares stimulus features with memory content.

The EU’s Choice of Regulatory Venues for Trade Negotiations: A Tale of Agency Power?

This article focuses on the EU’s strategy for choosing regulatory venues to negotiate trade agreements. It analyses the existence of a clear venue hierarchy since the late 1990s and the recent change leading to a blurring of any clear preference for using bilateral, inter-regional or multilateral settings. The article challenges domestic explanations of the EU’s choice of venue, stressing the autonomy of the Commission as a major factor. Using a principal-agent framework, it shows that the Commission’s agenda-setting powers, the existence of interest divergence among principals (e.g. Member States, business groups) and the multi-level system facilitate agency.

Communion-over-Agency effects on advertising effectiveness

Gender-stereotypical portrayals of communal women and agentic men are highly common in advertising. But past research indicates that advertising effectiveness is higher when endorsers are portrayed as communal – irrespective of their gender. The aim of the current research is to explore this communion-over-agency effect on advertising effectiveness and its underlying mechanism. Two studies provide evidence for a communion-over-agency effect on advertising effectiveness (i.e., attitude toward the ad and brand). These studies show that the communion-over-agency effect on attitude toward the ad is mediated by endorser likeability (simple mediation). The effect on attitude toward the brand is mediated by endorser likeability and attitude toward the ad (serial multiple mediation). In concert, this research underscores the significance of communion (and agency) on endorser evaluation and advertising effectiveness.

Valence and agency influence striatal response to feedback in patients with major depressive disorder

BACKGROUND: Reduced sensitivity to positive feedback is common in patients with major depressive disorder (MDD). However, findings regarding negative feedback are ambiguous, with both exaggerated and blunted responses being reported. The ventral striatum (VS) plays a major role in processing valenced feedback, and previous imaging studies have shown that the locus of controls (self agency v. external agency) over the outcome influences VS response to feedback. We investigated whether attributing the outcome to one's own action or to an external agent influences feedback processing in patients with MDD. We hypothesized that depressed participants would be less sensitive to the feedback attribution reflected by an altered VS response to self-attributed gains and losses. METHODS: Using functional MRI and a motion prediction task, we investigated the neural responses to self-attributed (SA) and externally attributed (EA) monetary gains and losses in unmedicated patients with MDD and healthy controls. RESULTS: We included 21 patients and 25 controls in our study. Consistent with our prediction, healthy controls showed a VS response influenced by feedback valence and attribution, whereas in depressed patients striatal activity was modulated by valence but was insensitive to attribution. This attribution insensitivity led to an altered ventral putamen response for SA - EA losses in patients with MDD compared with healthy controls. LIMITATIONS: Depressed patients with comorbid anxiety disorder were included. CONCLUSION: These results suggest an altered assignment of motivational salience to SA losses in patients with MDD. Altered striatal response to SA negative events may reinforce the belief of not being in control of negative outcomes contributing to a cycle of learned helplessness.
