Individualism versus interactionism about social understanding

In the debate about the nature of social cognition we see a shift towards theories that explain social understanding through interaction. This paper discusses autopoietic enactivism and the we-mode approach in the light of such developments. We argue that a problem seems to arise for these theories: an interactionist account of social cognition makes the capacity of shared intentionality a presupposition of social understanding, while the capacity of engaging in scenes of shared intentionality in turn presupposes exactly the kind of social understanding that it is intended to explain. The social capacity in question that is presupposed by these accounts is then analyzed in the second section via a discussion and further development of Searle’s ‘sense of us’ and ‘sense of the other’ as a precondition for social cognition and joint action. After a critical discussion of Schmid’s recent proposal to analyze this in terms of plural pre-reflective selfawareness, we develop an alternative account. Starting from the idea that infants distinguish in perception between physical objects and other agents we distinguish between affordances and social affordances and cash out the notion of a social affordance in terms of “interaction-oriented representations”, parallel to the analysis of object affordances in terms of “action-oriented representations”. By characterizing their respective features we demonstrate how this approach can solve the problem formulated in the first part.     

Evidence that baroreflex feedback influences long-term incidental visual memory in men

Sympathetic nervous system (SNS) activity at the time of acquisition is associated with human memory. However, rather than SNS activity per se, it may be afferent baroreflex feedback that is responsible for this effect. A pharmacological design was employed to unload (SNP, sodium nitro-prusside) and load (norepinephrine) baroreceptors. In addition to two placebo periods, epinephrine and esmolol (a peripherally acting beta1-blocker) served as control conditions for altered cardiac perception. During drug infusion blood pressure, heart rate, and perception of heartbeat were tested. Twenty-four healthy men were participated. The participants viewed emotional slides while their electromyographic eye blink responses to random noise bursts were measured (affective startle modulation paradigm) to determine potential drug impact on emotional processing. Subjects were not informed that memory testing would take place after 4 weeks. Drugs did not impact startle, thus indicating unbiased emotional processing at the time of acquisition. Norepinephrine had no effect on heartbeat perception, but improved (p = .002) recognition memory. SNP (p = .0001) increased heartbeat perception but impaired (p = .038) recognition memory. Epinephrine, on the other hand, increased heartbeat perception (p = .0001) yet did not impair but partially improve memory (effect on high arousing pictures only: p = .05). Heartbeat perception in the placebo condition did not correlate with recognition memory (p's > .5). We suggest that baroreflex unloading, with subsequent feedback activation of the SNS, impairs long-term incidental visual recognition memory in humans while baroreflex loading enhances it. Further, we propose that these memory effects are neither secondary to cardiac sensations that accompany SNS activation nor to altered emotional picture processing at the time of acquisition.     

Whom would you rather help: an acquaintance not responsible for her plight or a responsible sibling?

When 2 persons--an acquaintance who could not have avoided a problem and a close relative who is responsible for her own plight--ask for help, attribution theory and sociobiology conflict about who will receive help. Attribution theorists assume that the nonresponsible acquaintance will be supported, but sociobiologists argue that the responsible sibling will receive help. The authors tested the hypothesis that characteristics of the situation affect which theory better predicts help giving. The results confirmed that in situations that do not affect life and death, a nonresponsible acquaintance would receive more help than a responsible sibling. But in life-or-death situations, inasmuch as the reproductive fitness of the person in need is in danger, a responsible sibling would be supported more than a nonresponsible acquaintance.     

Self-Efficacy and Causal Attributions: Direct and Reciprocal Links

This study examines Bandura's (1986, 1997a) propositions that self-efficacy provides information from which causal attributions are made and that causal attributions, in turn, influence formation of subsequent self-efficacy expectations. We developed a conceptual rationale for and empirically tested 2 sets of hypotheses pertaining to direct and reciprocal links between self-efficacy and causal attributions. Effects of causal attributions and subsequently formed self-efficacy on subsequent task performance were also investigated. Results support the existence of direct and reciprocal links between self-efficacy and causal attributions. We found interactive effects between self-efficacy and performance feedback on causal attributions, and a mediating effect of causal attributions on the formation of subsequent self-efficacy beliefs. Causal attributions and subsequent self-efficacy also significantly predicted subsequent performance.
