123s and ABCs: developmental shifts in logarithmic‐to‐linear responding reflect fluency with sequence values

When placing numbers along a number line with endpoints 0 and 1000, children generally space numbers logarithmically until around the age of 7, when they shift to a predominantly linear pattern of responding. This developmental shift of responding on the number placement task has been argued to be indicative of a shift in the format of the underlying representation of number (Siegler & Opfer, 2003 ). In the current study, we provide evidence from both child and adult participants to suggest that performance on the number placement task may not reflect the structure of the mental number line, but instead is a function of the fluency (i.e. ease) with which the individual can work with the values in the sequence. In Experiment 1, adult participants respond logarithmically when placing numbers on a line with less familiar anchors (1639 to 2897), despite linear responding on control tasks with standard anchors involving a similar range (0 to 1287) and a similar numerical magnitude (2000 to 3000). In Experiment 2, we show a similar developmental shift in childhood from logarithmic to linear responding for a non‐numerical sequence with no inherent magnitude (the alphabet). In conclusion, we argue that the developmental trend towards linear behavior on the number line task is a product of successful strategy use and mental fluency with the values of the sequence, resulting from familiarity with endpoints and increased knowledge about general ordering principles of the sequence.A video abstract of this article can be viewed at: http://www.youtube.com/watch?v=zg5Q2LIFk3M     

Capitalism and the Banality of Desire

ABSTRACT

This paper elaborates on Todd McGowan’s perspicacious, psychoanalytic explanation of capitalism’s resilience, due to its formidable ideological insinuation into the banal micro-desires of consumers. I outline his contention that capitalism’s false promise of future satisfaction is subverted by the psychical change indicated by Freud’s re-evaluation of the desire/satisfaction relationship. This is elaborated on via Lacan’s claim, somewhat underplayed in McGowan’s reflections, that desire is essentially narcissistic. Lacan’s claim raises the stakes of capitalism’s psychic appeal, but also indicates how Lacanian psychoanalysis offers a point of intervention. I briefly point to the consistency between Lacan’s conception of the actualized subject and Deleuze’s and Guattari’s articulation of desire in terms of “the process” and the complex metaphor of “desiring machines”. I finally turn to ?i?ek’s conception of the developing world as “the place of rupture” and a major fault line internal to capitalism that threatens to disrupt its operation.     

Temporal order judgments with amnesia

The hypothesis that patients with anterograde amnesia fail to recognize the temporal relations among recognizable past events was evaluated. Experiment 1 showed that order recognition for words in a list was at chance levels even though event recognition was significantly above chance. The same pattern did not obtain for intact adults. Experiment 2 examined event and order recognition for news events. Amnesics' event recognition for news events was quite accurate and comparable to controls, yet their order recognition was significantly below that of controls, again at chance levels. It is argued that the failure to encode the temporal relations among events has broad consequences for memory performance in general.
