142 3. Cognitive Sciences and Psychology<br />

forms invariably is directly and intimately engaged in cognitive processes, because such processes<br />

invariably require some means of control: consciousness provides the means of that<br />

control; consciousness is that control. This paper will outline the functional contribution of<br />

consciousness to cognitive processing, and provide an operational elucidation, together with<br />

supporting mechanisms linked to specific brain activity, to explain how cognitive processing<br />

itself develops through major transitional phases as each individual matures. In particular, basic<br />

human cognition, at first similar to the processing of other mammals, is shown to respond<br />

to an exogenous form of control vehicle whose remarkable efficacy leads to the introduction<br />

of new kinds of cognition. The major survival benefit of this elaborated cognitive competence<br />

is to catalyse the introduction of deliberate navigational tasking to exadaptively complement<br />

a default and reactively instrumental form of challenge response. At each stage of advanced<br />

cognitive processing, it is the emerging flexibility of new kinds of conscious control over<br />

cognition that lead each transition. Empowered by a syntactically sequence-oriented cognitive<br />

phase catalysed by linguistic symbolism, the ultimate transition to self-conscious control<br />

is formulated upon a previously un-described form of internal perspective-taking over<br />

many forms of knowledge, which serves in the case of the self-model to afford a particular<br />

two-dimensional field of control over navigational tasking which subsumes simpler forms of<br />

conscious control. The process-oriented ratio-cognitive mode of sequence control thus gives<br />

over to a more target-oriented 2d-balance-board (‘intuitive’) form of control. Unable to be<br />

repudiated once acquired, the operational self-model, characteristic of navigational tasking,<br />

systematically invests in the (forgone) behavioral repertoire which increasingly subserves intelligent<br />

performance. Seeing cognitive work, cognitive progress and cognitive control as<br />

three separate analytical dimensions of the higher-order percept-action cycle, one can trace<br />

the mammalian episodic unit of behaviour (stimulus control, via cues) into a quad-template,<br />

sequence-management framework of phrasic instrumental competences (sequence control,<br />

via symbol-pointers). Extensive experience and automation of stereotyped sequence-management<br />

foreshadows a redirection of attentive focus towards external objectives, where a<br />

vector-oriented target-choice system of control (self control) capable of training expectations<br />

towards achievability begins to take over. Three major phases of cognitive advance delineate<br />

cognitive development, themselves predicated upon variously five (capabilities), three (levels)<br />

and two (stances) principal components of cognition. Consciousness as control, cognitive<br />

processing itself and cognitive representation thus continue to morph coherently from<br />

less- into ever more-elegant, efficient and effective forms of cognition as domain mastery<br />

progresses. It is precisely the experience of this progress that eventually yields the personal<br />

conviction that so much remains to be known. P3<br />

197 Imagination and the Psychology of Mind-Wandering Peter Langland-Hassan<br />

(Washington University in St. Louis, St. Louis, MO)<br />

Imagining is an important form of “mind-wandering” or “stimulus-independent” thought.<br />

Are the mental states that constitute imaginings (and “conceivings”) sui generis in their basic<br />

nature, or can they be identified with better understood mental states, such as perceptions and<br />

beliefs? By what principles do imaginative mental states causally interact with other mental<br />

states? How precise can we be about their functional role? In seeking traction on these questions,<br />

I set out a number of desiderata for a psychological theory of imagination. These include<br />

features such as imagination?s creativity, its usefulness in practical reasoning, its link to judgments<br />

of possibility, its active nature, and its occasional limits. I then outline an account of<br />

both “propositional” and “sensory” imagination aimed at satisfying these desiderata. According<br />

to this account, both propositional and sensory imagining consist in forming or retrieving<br />

beliefs in conditional probabilities. To (propositionally) imagine that it is raining is (roughly)<br />

to infer or retrieve beliefs in conditionals of the form: “Probably, if it were raining, then x, y,<br />

and z.” To (sensorily) imagine a blue apple is to infer or retrieve a believed conditional of the<br />

form: “Probably, if there were a blue apple it would look roughly like: A,” where A represents<br />

the contribution of a mental image to the imagining. While such view allows for an attractive<br />

explanatory reduction of imagination to belief, many will find it counterintuitive. I indicate<br />

how certain features of imagination?e.g., its creativity and freedom?that seem to clash with
