Although the analogy between dreams and ancient mnemotechniques is tempting because they share several phenomenological characteristics, this analogy is superficial at a closer look. Unlike mneomotechnically encoded material, rapid eye movement (REM) dreams are inherently difficult to remember, do not usually allow conscious subsequent retrieval of all interconnected elements, and ...
Greenberg Ramon - - 2013
Whereas the target article stresses the neurobiology and psychology of dreams, this commentary emphasizes that the role of dreams in emotional integration and adaptation contributes to a fuller understanding of dreaming and memory. The dream presented in the target article is used, within the constraints of space, as a possible ...

I make three points. First, processors and depletable resources should not be regarded as alternative means of processing information: they are both necessary. Second, comparing a processor account with a rational allocation mechanism to a depletable-resources account without one is not a fair comparison. Third, depletable resources can act as ...

An opportunity cost model of effort requires flexible integration of valuation and self-control systems. Reciprocal connections between these networks and brainstem neuromodulatory systems are likely to provide the signals that affect subsequent persistence or failure when faced with effort challenges. The interaction of these systems should be taken into account ...
Molden Daniel C - - 2013
Kurzban and colleagues propose that experiences of effort alter motivations to persist during goal pursuit by highlighting costs of persistence. I expand this proposal by discussing how effort experiences (a) not only influence, but can be influenced by motivations to persist on a goal; and (b) not only highlight costs ...

Kurzban et al. make a convincing case against the idea that willpower is a depleting resource. However, they do not advance a positive account of willpower. Rather than treating "willpower" as a synonym of "executive function," we argue that the term willpower should be designated for mechanisms individuals deploy to ...

Though the aversiveness of effort may indeed serve in selecting tasks for executive attention, the notion that it reflects opportunity costs is questionable: The potency of distractions in real-life situations is not regularly related with the potential benefit from attending to them.
Westbrook John Andrew - - 2013
If cognitive effort indexes opportunity costs, it should be investigated like other cost factors including risk and delay. We discuss recent methodological advances in behavioral economics and neuroeconomics, highlighting our own work in measuring the subjective (economic) value of cognitive effort. We discuss the implications of Kurzban et al.'s proposal ...
