Reflecting on the action or its outcome: Behavior representation level modulates high level outcome priming effects on self-agency experiences

Recent research suggests that one can have the feeling of being the cause of an action’s outcome, even in the absence of a prior intention to act. That is, experienced self-agency over behavior increases when outcome representations are primed outside of awareness, prior to executing the action and observing the resulting outcome. Based on the notion that behavior can be represented at different levels, we propose that priming outcome representations is more likely to augment self-agency experiences when the primed representation corresponds with a person’s behavior representation level. Three experiments, using different priming and self-agency tasks, both measuring and manipulating the level of behavior representation, confirmed this idea. Priming high level outcome representations enhanced experienced self-agency over behavior more strongly when behavior was represented at a higher level, rather than a lower level. Thus, priming effects on self-agency experiences critically depend on behavior representation level.     

Increased interoceptive awareness in fear of flying: sensitivity to suffocation signals

In flight phobia, particular environmental factors can facilitate a fear response. The current study aimed to explore the relationship between respiratory sensations and fear of flying: individuals with fear of flying may be more sensitive to suffocation signals and could experience more bodily sensations as a consequence of an added resistive respiratory load. The sample included 19 subjects with fear of flying and 19 controls. Each subject wore a mask to which a respiratory load could be added. First, an interference paradigm was used: respiratory loads were presented during a tone detection task. Next, subjects were asked to detect the loads. After each task, subjects reported their somatic sensations. All subjects showed interference of the respiratory loads. However, subjects with fear of flying were more accurate in detecting the loads, thereby indicating higher interoceptive awareness. Moreover, their superior accuracy was related to increased bodily sensations: a higher interoceptive awareness resulted in increased symptom reporting. It follows that treatment interventions for fear of flying should be supplemented with interventions that target internal stimuli.     

The effect of methylphenidate on three forms of response inhibition in boys with AD/HD

The current study was aimed at (a) investigating the effect of three doses methylphenidate (MPH) and placebo on inhibition of a prepotent response, inhibition of an ongoing response, and interference control in Attention Deficit/Hyperactivity Disorder (AD/HD), and (b) studying dose-response relations for the three forms of response inhibition. To meet these aims, the following tasks were selected: two versions of the Stop Paradigm for inhibition of a prepotent response, a Circle Tracing Task and a recently developed Follow Task for inhibition of an ongoing response, and the Stroop Color-Word Test and an Eriksen Flanker Task for interference control. These tasks were administered to 23 boys with AD/HD during four treatment conditions: 5 mg MPH, 10 mg MPH, 20 mg MPH, and placebo. A pseudorandomized, multiple-blind, placebo-controlled, within-subject design was used. As hypothesized, inhibitory control in children with AD/HD improved under MPH compared to placebo. However, this effect was only significant for inhibition of a prepotent response and inhibition of an ongoing response (as measured by the Follow Task), but not for interference control. The relation between treatment condition and response was linear. However, this linear relation was due to improved inhibitory control under MPH compared to placebo, because no effects of MPH dose were observed for any of the response inhibition measures.     

The phenomenology of protest atmosphere: A demonstrator perspective

This paper aims to improve our understanding of demonstrators' atmosphere perceptions, that is, demonstrators' affective state, which is induced by the protest environment. We examined how demonstrators perceive protest atmosphere, why they do so, and whether atmosphere perceptions influence demonstrators' future collective action preparedness. We hypothesized that demonstrators' atmosphere perceptions diverge on a dimension of pleasure, and relate to their grievance (i.e., perceived societal intolerance), group identification, empowerment, and perceived police aggression. A pleasant atmosphere perception was expected to stimulate a demonstrator's future action preparedness. We tested these hypotheses with a mixed‐methods dataset of two Dutch protests, staged by Lesbians, Gays, Bisexuals, and Transgenders and anti‐monarchists. Our analyses revealed that demonstrators' atmosphere perceptions diverge on a dimension of pleasure, and relate to group identification, empowerment, and, for anti‐monarchists, perceived societal intolerance. A pleasant atmosphere perception deters a demonstrator's future action preparedness and also stimulates his or her group identification and empowerment, which, then, stimulate his or her action preparedness.

Personality traits that distinguish you and me are better memorized

Female participants described themselves via desirable and undesirable traits that they possessed or lacked. For each trait, they then received feedback informing them whether they were similar to, or different from a female target. After a distracting task, participants received a recognition test and completed a recall test of the traits. The traits that allowed the participant to be differentiated from the target (because they were applicable to one but not the other) were best recognized and recalled. Undesirable traits were better recognized than desirable ones. However, the picture of the target emanating from the recall data presents her in a very desirable way. The results are discussed within a pragmatic framework. ©1997 John Wiley & Sons, Ltd.     

Predicting Treatment Response in Older Adults with Insomnia

This study examined potential predictors of treatment outcome in late-life insomnia. Fifty-four older adults with chronic insomnia were treated with cognitive–behavior therapy (CBT), pharmacotherapy (PCT), or combined CBT plus PCT. Pretreatment characteristics such as demographic, clinical, psychometric, and sleep variables were examined as correlates or potential predictors of treatment response. Treatment response was defined by posttreatment sleep efficiency as measured subjectively by daily sleep diary and objectively by polysomnography. The results indicate that age, insomnia duration, medical illness, and previous use of sleep medications can moderate subjective or objective treatment outcome or both of these in late-life insomnia. However, there are no reliable predictors of outcome across all treatment and assessment modalities. The implications of these findings for the treatment of insomnia in older adults seen in primary care settings are discussed.     

Computer simulations as experiments

Whereas computer simulations involve no direct physical interaction between the machine they are run on and the physical systems they are used to investigate, they are often used as experiments and yield data about these systems. It is commonly argued that they do so because they are implemented on physical machines. We claim that physicality is not necessary for their representational and predictive capacities and that the explanation of why computer simulations generate desired information about their target system is only to be found in the detailed analysis of their semantic levels. We provide such an analysis and we determine the actual consequences of physical implementation for simulations. A. Barberousse, S. Franceschelli and C. Imbert have contributed equally to this work.     

On The Nature of Experiencing Self‐Agency: The Role of Goals and Primes in Inferring Oneself as the Cause of Behavior

People often find themselves in situations where the cause of events may be ambiguous. Surprisingly though, the experience of self‐agency, i.e., perceiving oneself as the causal agent of behavioral outcomes, appears quite natural to most people. How then do these experiences arise? We discuss common models proposing that self‐agency experiences result from the comparison between actual action‐outcomes and the outcomes one explicitly set as a goal. However, recent developments in psychology and neuroscience suggest that our behaviors and the outcomes they produce can be primed and implicitly guided by environmental cues and yet are accompanied by experiences of self‐agency. Hence, we also review research revealing how self‐agency experiences may arise over behavioral outcomes that are implicitly primed before they occur and how such implicitly cued agency experiences may differ from agency experiences that are the result of explicitly set goals. Directions for future research are briefly addressed.     

The presence of the past: Identity continuity and group dynamics

Social psychologists are increasingly interested in the temporal dimensions of social life and in identity continuity in particular. Focusing on ethnicity and national identity we discuss the implications of perceived group continuity and collective self-continuity, and their interplay, for group dynamics. Using the social identity perspective and theories of identity motivation, we show, first, that the need for collective self-continuity forms a unique motivational basis for group identification. Second, we demonstrate that people are more likely to derive a sense of collective self-continuity from groups that are seen as relatively stable and immutable over time (i.e., essentialist in-groups). Third, we find that existential threats to group identity strengthen a sense of collective self-continuity, which, in turn, increases in-group defence mechanisms in the form of negative attitudes towards immigrant out-groups and towards social developments that potentially undermine in-group continuity. Fourth, we discuss empirical findings that indicate that group-based nostalgia for the nation is an identity management strategy in response to in-group continuity threats and that nostalgia leads to immigrant out-group exclusion.
