A series of four experiments tested the assumptions of the most prominent and longstanding account of item-method directed forgetting: the selective rehearsal account. In the item-method directed forgetting paradigm, each presented item is followed by its own instructional cue during the study phase - either to-be-forgotten (F) or to-be-remembered (R). On a subsequent test, memory is poorer for F items than for R items.

These are single-item recognition (including the remember/know paradigm), recognition in relational context, associative recognition, and source monitoring. The contrast, with regards to the double-miss rate (the probability of recognizing neither item in intact and rearranged pairs) and the effect of the oldness of the other member of the test pair, between identifying the old words in test pairs (the relational context paradigm) and first identifying the intact test pairs and then identifying the old words (adding associative recognition to the relational context paradigm) suggests that the retrieval of associative information in the relational context paradigm is unintentional, unlike the retrieval of associative information in associative recognition.

This study examined the mechanism for the recognition advantage for pictures. In Experiment 1A, pictures and sounds were presented in separate trials in a mixed list during the study phase and participants showed in a yes-no test, a higher proportion of correct responses for targets, exemplar foils categorically related to the target, and novel foils for pictures compared with sounds.

According to the cue-overload account of context effects (Rutherford, 2004), context acts like any other cue, and thus context effects should be larger with lighter context loads. Conversely, the Item, Associated Context, and Ensemble (ICE) account (Murnane et al.

Mandler (1980, ) proposed that recognition decisions could be based on the sense of familiarity engendered by the stimulus or on the retrieval of conceptual, semantic, and contextual information about the target. These two distinctions have motivated a considerable amount of research over the past 40 years and have provided much of the bases for our current understanding of recognition memory.

For example, low frequency words have a higher hit rate and a lower false alarm rate than high frequency words. Because the mirror effect is held to be a regularity of memory, it has had a pronounced influence on theories of recognition.

The list-strength effect (LSE) refers to the finding that, compared to unstrengthened (pure) lists, lists for which a subset of the items have been strengthened produce enhanced memory for the strengthened items and depressed memory for the unstrengthened items. Although the LSE is found in free recall (Tulving & Hastie, 1972), it does not occur in recognition (Ratcliff et al.

In the present work, we test this hypothesis by implementing a double-item presentation within the item-method directed forgetting paradigm. Participants studied two unrelated items at a time.

This debate was initiated when Dennis and Humphreys (2001) showed that, when confounds present in earlier list-length experiments were controlled, the list-length effect disappeared. The issue has yet to be settled.

In the present study, we apply a computational model to data from a simple short-term memory task and demonstrate that decay and interference can co-occur in the same experimental paradigm, and that neither decay nor interference alone can account for all cases of forgetting.

The effect of item-based directed forgetting (DF) on recognition memory for categorized word lists was examined. For half of the categories, all studied exemplars were followed by a remember cue; for the other half of the categories, all studied exemplars were followed by a forget cue. In Experiment 1, a 2-alternative forced-choice recognition test showed decreased recognition for to-be-forgotten items.

Dual-coding theory (DCT; Paivio, 1991 ) is often used to explain the PSE. According to DCT, pictures are more likely to be encoded imaginally and verbally than words.

When the distractor is from the same category as the target (exemplar test condition), discrimination must be based on memory for perceptual details, whereas recognition can be based on gist or general category information when the distractor is from a novel category (novel test condition). Recognition accuracy was greater for Remember-cued than Forget-cued pictures when discrimination must be based on perceptual details in the exemplar test condition but not when discrimination could be based on gist in the novel test condition.

To assess how these aspects of actions affect the sense of agency, we asked participants to perform freely selected or instructed key presses which could produce pleasant or unpleasant chords. We obtained estimates of the key press-chord intervals and ratings of the feeling of control (FoC) over the outcomes.

Here, we investigated whether choice space could affect subjective judgments of mental effort experienced during action selection and examined the link between subjective effort and the SoA. Participants performed freely selected (among two, three, or four options) and instructed actions that produced pleasant or unpleasant tones.

While some previous studies have reported greater interference when irrelevant information is similar to the contents of memory than when it is dissimilar, other studies have reported greater interference for dissimilar distractors than for similar distractors. In the present study, we find the latter effect in a paradigm that uses auditory tones as stimuli.

Item and associative recognition were both greater for word pairs followed by a remember (R) cue than a forget (F) cue. Associative discrimination for F-cued pairs was above chance in most conditions, demonstrating that relational informational is encoded incidentally.

Recent research has suggested the existence of a modality-independent memory system that is responsible for storing representations of simple, scalar stimulus attributes, such as the frequency of an auditory pure tone or the duration of a stimulus. In the present study, we modify an existing computational model of short-term memory (STM) for stimulus frequency to allow it to perform STM tasks for both stimulus frequency and stimulus duration, supporting the notion of a common scalar STM system. We further demonstrate the utility of the model by showing that it can reproduce the subjective shortening effect, a classic finding in the psychophysical literature.

We present six experiments in a different empirical framework examining false recognition of words included in the experimental instructions (instruction-set lures). The data show that participants' false alarm rate to instruction-set lures was twice their false alarm rate to standard lures.
