RESUMO
Two issues are discussed. The first one pertains to the generality of the nonconscious learning processes and their somewhat paradoxical status in cognitive psychology. We argue that the ability of the human cognitive system to nonconsciously acquire complex knowledge structures is one of its elementary and indispensable properties. Moreover, the existence of this ability constitutes one of the necessary metatheoretical assumptions of contemporary cognitive psychology. Nevertheless, the contemporary cognitive psychology literature often implies that it is only one of many controversial and unusual phenomena. The second issue pertains to the distinction between the so-called primitive unconscious and the sophisticated unconscious as proposed by Reber (1989).

Indirect (transitive) inference (i.e., if A is related to B, and B is related to C, then C is related to A) is a ubiquitous component of thinking and reasoning. This research demonstrates that a mechanism at least functionally similar to drawing indirect inferences can also be observed in unintentional processes of encoding. The 2 studies followed the same design and used modified versions of procedures tested in previous research on nonconscious information processing (P. Lewicki, T. Hill, & M. Czyzewska, 1992). In the first learning phase, Ss acquired an encoding algorithm relating Variables A and B. In the second learning phase, Variable A was removed from the material and replaced with Variable C, allowing Ss to acquire the second encoding algorithm (relating B and C). Consistent with the original studies, Ss were not aware that there were any consistencies in the material. In the testing phase material, Variable B was removed, and Ss were asked to make intuitive judgments regarding Variable A. The data from both experiments confirmed the expectation that Ss would implicitly draw indirect inferences (A on the basis of C). This process is discussed as one of the mechanisms that may trigger the development of various components of procedural knowledge.

The process of encoding new information involves the imposition of preexisting interpretive categories on newly encountered stimuli, even if the categories do not match perfectly those stimuli. We hypothesized that such encoding of stimuli as supportive of preexisting encoding dispositions may become a source of a perceiver's subjective experiences that support these dispositions. Through this nonconsciously operating mechanism, encoding rules may gradually develop in a self-perpetuating manner, even in the absence of any objectively supportive evidence. Results demonstrated this self-perpetuating process in three studies involving different stimulus materials and experimental tasks (matrix-scanning paradigm and two "intuitive judgment" tasks). The self-perpetuating development of encoding biases is discussed as one of the elementary mechanisms involved in the development of interpretive categories and other individually differentiated cognitive dispositions.

It was hypothesized that encoding (interpretive) biases may develop in a self-perpetuating manner through biased, self-supportive encoding (even in the absence of any objectively supportive evidence). This process was investigated in 3 experiments with different stimulus materials (matrices of digits, silhouettes of persons, descriptions of personal problems). In the learning phase of each study, Ss nonconsciously acquired some encoding bias. In the testing phase, Ss' encoding of new material was predictably biased, and, consistent with the self-perpetuation hypothesis, the strength of the bias gradually increased over the segments of the material, even though the material did not contain any evidence supportive of the bias. Given the ambiguity of many (particularly social) stimuli, the self-perpetuation process may play a ubiquitous role in the development of interpretive categories and other individually differentiated cognitive dispositions.

The authors review and summarize evidence for the process of acquisition of information outside of conscious awareness (covariations, nonconscious indirect and interactive inferences, self-perpetuation of procedural knowledge). Data indicate that as compared with consciously controlled cognition, the nonconscious information-acquisition processes are not only much faster but are also structurally more sophisticated, in that they are capable of efficient processing of multidimensional and interactive relations between variables. Those mechanisms of nonconscious acquisition of information provide a major channel for the development of procedural knowledge that is indispensable for such important aspects of cognitive functioning as encoding and interpretation of stimuli and the triggering of emotional reactions.

H. Hendrickx, J. De Houwer, F. Baeyens, P. Eelen, and E. Van Avermaet (1997) reported a series of (mostly unsuccessful) studies on nonconscious hidden covariation detection (HCD); for example, they reported that out of 3 attempts to replicate P. Lewicki et al.'s studies, only 1 produced the expected results. They concluded that HCD may be not as general and robust as the previous research suggested, and they considered boundary conditions. In this article, the authors discuss a number of weaknesses of H. Hendrickx et al.'s experiments (and systematic deviations from the original methodology) that are potentially responsible for the lack of the expected results and discuss missing facts in their arguments (e.g., they failed to mention any published replications of the HCD studies from other than the present authors' laboratories). It is argued that when all evidence is considered, the proper conclusion is that nonconscious processing of covariations is not only general and robust but also a ubiquitous phenomenon mediating a variety of processes of acquisition of information.
