We report the first evidence that the gist mechanism of fuzzy-trace theory and the associative mechanism of activation monitoring theory operate in parallel, in the recall version of the Deese/Roediger/McDermott illusion. In three experiments, we implemented a new methodology that allows their respective empirical indexes, gist strength (GS) and…

Foraging refers to behavior that exploits the current environment for resources and induces exploration for a better environment. Visual foraging tasks have been used to study human behavior during visual searches. Participants searched for target stimuli among the distractors and either acquired or lost points when they clicked on a target or…

We report three item-method directed forgetting (DF) studies to evaluate whether DF impairs primarily item memory, or whether it also impairs associative memory. The current studies used a modified associative recognition paradigm that allowed disentangling item impairment from associative impairment in DF. Participants studied scene-object…

Stimuli presented with targets during a monitoring task are better remembered than stimuli presented with distractors, a result referred to as the attentional boost effect (ABE). The ABE is consistently found for item memory, but conflicting results have been reported for different assessments of associative memory, with studies of source memory…

In six experiments, we tested whether immediate serial recall is influenced by a word's degree centrality, an index of lexical connectivity. Words of high degree centrality are associated with more words in free association norms than those of low degree centrality. Experiment 1 analyzed secondary data to explore the effect of degree centrality in…

Semantic similarity between stimuli can lead to false memories and can also potentially cause retroactive interference (RI) for veridical memories. Here, participants first learned spatial locations for "critical" words that reliably produce false memories in the Deese-Roediger-McDermott paradigm. Next, participants centrally viewed…

Does serial learning result in specific associations between pairs of items, or does it result in a cognitive map based on relations of all items? In 2 experiments, we trained human participants to learn various lists of photographic images. We then tested the participants on new lists of photographic images. These new lists were constructed by…

Learning to categorize perceptually similar stimuli can result in people becoming more sensitive to differences along perceptual dimensions that are relevant to category membership and/or less sensitive to equivalent differences along irrelevant perceptual dimensions. These effects of acquired distinctiveness and acquired equivalence may be caused…

We examined 3 different network models of representing semantic knowledge (5,018-word directed and undirected step distance networks, and an association-correlation network) to predict lexical priming effects. In Experiment 1, participants made semantic relatedness judgments for word pairs with varying path lengths. Response latencies for…

Long-term semantic memory (LTM) is known for affecting recall during working memory (WM) tasks. However, the way LTM intervenes in WM remains unknown. Moreover, the available findings are incongruent concerning how attention modulates the impact of LTM on WM. To examine this issue, the involvement of LTM representations in a complex span task was…

Recent context-control learning studies have shown that switch costs are reduced in a particular context predicting a high probability of switching as compared to another context predicting a low probability of switching. These context-specific switch probability effects suggest that control of task sets, through experience, can become associated…

Human word learning is remarkable: We not only learn thousands of words but also form organized semantic networks in which words are interconnected according to meaningful links, such as those between "apple," "juicy," and "pear." These links play key roles in our abilities to use language. How do words become…

Attempting to guess an answer to a memory question has repeatedly been shown to benefit memory for the answer compared to merely reading what the answer is, even when the guess is incorrect. In this study, we investigate 2 potential explanations for this effect in a single experimental procedure. According to the semantic explanation, the benefits…

The "Perruchet effect" refers to a dissociation between the conscious expectancy of an outcome and the strength or speed of responding in anticipation of that outcome. This dissociation is considered by some to be the best evidence for multiple learning processes with expectancy governed by participants' explicit beliefs and responding…

In 2 experiments, eye-tracking was used to examine individual differences in attention during encoding and their relation to associative learning. Pupillary responses were used as an indicator of the amount of attention devoted to items, whereas eye fixations provided a means of assessing attentional focus among items within each to-be-remembered…
