I present a framework for modeling memory, retrieval, perception, and their interactions. Recent versions of the models were inspired by Bayesian induction: We chose models that make optimal decisions conditioned on a memory/perceptual system with inherently noisy storage and retrieval. The resultant models are, fortunately, largely consistent with my models dating back to the 1960s, and are therefore natural successors. My recent articles have presented simplified models in order to focus on particular applications. This article takes a larger perspective and (...) places the individual models in a more global framework. I will discuss (1) the storage of episodic traces, the accumulation of these into knowledge (e.g., lexical/semantic traces in the case of words), and the changes in knowledge caused by learning; (2) the retrieval of information from episodic memory and from general knowledge; (3) decisions concerning storage, retrieval, and responding. Examples of applications include episodic recognition and cued and free recall, perceptual identification (naming, yes–no and forced‐choice), lexical decision, and long‐term and short‐term priming.

Mere exposure, generally, entails influences of familiarity manipulations on affective dependent variables. Previously (Phaf & Rotteveel, 2005), we have argued that familiarity corresponds intrinsically to positive affect, and have extended the correspondence to novelty and negative affect. Here, we present two experiments that show reverse effects of affective manipulations on perceived familiarity. In Experiment 1 affectively valenced exteroceptive cues of approach and avoidance (e.g., apparent movement) modulated recognition bias of neutral targets. This finding suggests that our correspondence hypotheses can be (...) generalised to an important aspect of emotion, namely approach and avoidance tendencies. In Experiment 2 participants? emotional mood was manipulated within the Jacoby?Whitehouse paradigm and a pattern of results was obtained as if consciousness was manipulated. We interpret the latter results within the affective modulation framework (AMF), which postulates facilitation of nonconscious processing by positive affect and an enhancement of conscious processing by negative affect.

Comparisons of indirect measures with direct measures can help elucidate the relationship between nonconscious and conscious perception. We report three experiments on masked word priming in which we observed a negative correlation between prime discriminability and priming , i.e. where priming decreased with increasing prime visibility. While such observations are rare , they may indicate a conflict between conscious and nonconscious processing when primes are shown close to the subjective visibility threshold for the priming-relevant information. For instance, such a conflict (...) could occur between nonconscious processing of a prime’s meaning and conscious perception of prime letters. Theoretical accounts that discuss similar conflicts assume that the conflict is resolved either by automatically prioritising conscious processes or by discounting the estimated confusion caused by a prime-target pair . In both cases, priming is predicted to decrease when prime visibility increases from below threshold to perithreshold levels. Therefore, we suggest that negative priming-d’ relationships are most likely observed when the d’ measure assesses prime visibility at a level of representation that is below the level of representation at which priming arises, in terms of a putative hierarchy of word processing.
