Computer-Aided Careers Guidance: An Investigation Involving an Artificial System

Customer satisfaction with the occupational suggestions provided by computer-aided guidance systems is uniformly high. User satisfaction and reactions to an artificial system, and two conventional and profile-matching system, were compared. The results suggested that user satisfaction is influenced by several factors which are largely unrelated to the quality or novelty of the occupational suggestions received. The project also raises several issues regarding the validity of profile-matching in comparison to other less-complex databank-reduction procedures.     

Harmony,structure, and force in the Essai analytique sur les facultés de l'âcme of Charles Bonnet

The psychological works of Charles Bonnet of Geneva (1720–1793) have customarily been read as part of the mentalistic traditions of associationism or Leibnizianism. They are better understood as part of a campaign—directed against the radical Enlightenment —to reclaim the human body for religion by the paradoxical strategy of incorporating a materialist conception of the human mind into the framework of divine providence. Bonnet's embodied psychology treats the soul as an intrinsically indeterminate force, and attributes the capacity of the mind to organize experience to highly specialized fibers, providentially constructed to correspond to the created world.

A defense of the very idea of moral deference pessimism

Philosophical Studies - Pessimists think that there is something wrong with relying on deference for one’s moral beliefs—at least if one is morally mature. Call this no deference. They...     

Negotiator cognitions: A descriptive approach to negotiators' understanding of their opponents

Substantial evidence exists that negotiators frequently fail to attain readily available and mutually beneficial outcomes. This paper provides a preliminary model of why these failures occur. We assume that negotiators are decision makers, and that their errors derive from cognitive processes ignored by utility-maximization theories. We focus on one part of the model: the systematic tendency to ignore the cognitions of opponent negotiators. Empirical evidence clarifying negotiators' cognitive processes is generated using verbal protocol techniques in a controlled negotiation task. The results show that subjects simplify the negotiation task, in part by ignoring contingencies introduced by the knowledge possessed by their opponents. The discussion focuses on how subjects simplify the task and how the decision-making perspective helps redirect the negotiation literature.     

Matching: its acquisition and generalization

Choice typically is studied by exposing organisms to concurrent variable-interval schedules in which not only responses controlled by stimuli on the key are acquired but also switching responses and likely other operants as well. In the present research, discriminated key-pecking responses in pigeons were first acquired using a multiple schedule that minimized the reinforcement of switching operants. Then, choice was assessed during concurrent-probe periods in which pairs of discriminative stimuli were presented concurrently. Upon initial exposure to concurrently presented stimuli, choice approximated exclusive preference for the alternative associated with the higher reinforcement frequency. Concurrent schedules were then implemented that gave increasingly greater opportunities for switching operants to be conditioned. As these operants were acquired, the relation of relative response frequency to relative reinforcement frequency converged toward a matching relation. An account of matching with concurrent schedules is proposed in which responding exclusively to the discriminative stimulus associated with the higher reinforcement frequency declines as the concurrent stimuli become more similar and other operants-notably switching-are acquired and generalize to stimuli from both alternatives. The concerted effect of these processes fosters an approximate matching relation in commonly used concurrent procedures.     

When parallel processing in visual word recognition is not enough: new evidence from naming

Low-frequency irregular words are named more slowly and are more error prone than low-frequency regular words (the regularity effect). Rastle and Coltheart (1999) reported that this irregularity cost is modulated by the serial position of the irregular grapheme-phoneme correspondence, such that words with early irregularities exhibit a larger cost than words with late ones. They argued that these data implicate rule-based serial processing, and they also reported a successful simulation with a model that has a rule-based serial component—the DRC model of reading aloud (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001). However, Zorzi (2000) also simulated these data with a model that operates solely in parallel. Furthermore, Kwantes and Mewhort (1999) simulated these data with a serial processing model that has no rules for converting orthography to phonology. The human data reported by Rastle and Coltheart therefore neither require a serial processing account, nor successfully discriminate among a number of computational models of reading aloud. New data are presented wherein an interaction between the effects of regularity and serial position of irregularity is again reported for human readers. The DRC model simulated this interaction; no other implemented computational model does so. The present results are thus consistent with rule-based serial processing in reading aloud.
