Target Words

Using behavioral evaluation of free recall performance, we investigated whether reverberation and/or noise affected memory performance in normal-hearing adults. Thirty-four participants performed a free-recall task in which they were instructed to repeat the initial word after each sentence and to remember the target words after each list of seven sentences, in a 2 (reverberation) × 2 (noise) factorial design. Pupil dilation responses (baseline and peak pupil dilation) were also recorded sentence-by-sentence while the participants were trying to remember the target words. In noise, speech was presented at an easily audible level using an individualized signal-to-noise ratio (95% speech intelligibility). As expected, recall performance was significantly lower in the noisy environment than in the quiet condition. Regardless of noise interference or reverberation, sentence- baseline values gradually increased with an increase in the number of words to be remembered for a subsequent free-recall task. Long reverberation time had no significant effect on memory retrieval of verbal stimuli or pupillary responses during encoding.

Portuguese Study

Eyewitness memory is widely studied in the forensic context, due to their proneness to make unreliable testimonies. Understanding which factors may impact memory is determinant to avoid wrongful convictions in court. In this exploratory study, the relation between stress and anxiety and memory errors (spontaneous and induced) was analyzed being hypothesized that negative emotions may impair memory performance. Crime and neutral videos were presented to 80 volunteer university students in a between subject-design. They were asked to fill some stress and anxiety scales throughout the experimental task, as well as a free recall task. Also, it was presented several questions about the videos in which spontaneous and induced errors were assessed. Results suggests that stress and anxiety did not influence the quantity of memory errors for both genders. However, overall memory performance was poor for both groups. Our results were discussed in light to existing theories about the relation between stress-anxiety and memory.

Dissociative Reactions

AbstractDissociative reactions during and subsequent to traumatic events are theorised to result in memory deficits for trauma-related information. This study investigated the interaction between induced amnesia and dissociative reactions. Participants (N = 29) were presented with a word list, a series of disfigured or neutral faces and a second word list, followed by free recall and recognition tasks. Participants presented with disfigured faces recalled fewer words from the postimage list in the free recall task than those presented with neutral faces; however, there were no between-group differences for recognition. No relationship was observed between dissociative tendencies and memory performance. Trait dissociation was unrelated to induced amnesia effects. Findings are interpreted in terms of impaired consolidation of information following encoding of distressing information. Implications of the results for the clinical management of traumatized individuals are considered.

The present study was designed to test the hypothesis that blood fearful and nonfearful individuals would be differentiated by their pattern of recall of schematic and non-schematic prose material. Blood fearful (n=36) and nonfearful (n=40) individuals were presented with five prose passages describing harm or injury. Nine sentences in each passage described events representative of the schema content of most individuals, whereas six sentences in each passage described events that are not representative of typical schema content. Participants read passages that either described themselves experiencing the situations or described themselves witnessing others in the situations and completed a free recall task in both immediate (i.e. 2 minutes) and delayed (i.e. one week) recall conditions. Results did not replicate studies from the cognitive psychology literature on which this study was based. Instead, participants who read passages describing themselves in these situations recalled the gist of the material more accurately than participants who read passages in which they witnessed another individual in the situation. Blood fearful participants recalled the affective tone of neutral passages less accurately than nonfearful participants. Results suggest that activation of schema content has little influence on memory performance, although assessing the affective tone of recalled material detected subtle differences in memory performance between fearful and nonfearful groups.

Retrieval Failure

The present experiment tested the hypothesis that retrograde induced amnesia is due to retrieval failure and anterograde induced amnesia to encoding failure by providing recall cues which were expected to eliminate retrograde amnesia but worsen or have no effect on anterograde amnesia. The 80 subjects received auditory presentation of 10 lists, each composed of 15 four-letter words presented at a rate of 2s/item at 75 dB in a free-recall task, followed by a 72 s recall period. The amnesia-producing event was an outstanding item in serial position 8 presented at 115 dB (about the intensity of a loud shout) on half the lists. During the first half of the recall period subjects free-recalled, but during the last half they were given a list of the first (single cue) or the first two (double cue) letters of each word, to be used as aids to recall. To demonstrate induced amnesia, lists containing a loud item were compared to those not containing one. First half free recall performance indicated that large retrograde and anterograde effects were present for both cue conditions. Second half cued recall performance indicated that in the double cue condition retrograde amnesia disappeared and anterograde amnesia became larger. Cueing had much smaller effects in the single cue condition.

Serial Position Curves

This study examined whether additional articulatory rehearsal induced temporary durability of phonological representations, using a 10-s delayed nonword free recall task. Three experiments demonstrated that cumulative rehearsal between the offset of the last study item and the start of the filled delay (Experiments 1 and 3) and a fixed rehearsal of the immediate item during the subsequent interstimulus interval (Experiments 2 and 3) improved free recall performance. These results suggest that an additional rehearsal helps to stabilize phonological representations for a short period. Furthermore, the analyses of serial position curves suggested that the frequency of the articulation affected the durability of the phonological representation. The significance of these findings as clues of the mechanism maintaining verbal information (i.e., verbal working memory) is discussed.

Lists of 10 dissyllables varying in meaningfulness were presented to subjects in a multiple-trial free recall task. Measures of recall and clustering showed superior recall and greater amounts of clustering for the high-meaningful list than for the low-meaningful list. Differential item integration and associative relatedness were mechanisms employed to explain the differences.

This article aims to reveal interaction between verbal intelligence and efficiency of intentional and incidental verbal information processing. Participants were exposed to pairs of words about which they have to decide whether a city name was presented in each pair. Thus, semantics of words was processed intentionally, whereas their phonemic features (rhymed vs. unrhymed pairs) were processed incidentally. The efficiency of stimuli processing was estimated in two different cognitive tasks – word free-recall task and word usage in new creative task. It was found that verbal intelligence was positively correlated with number of recalled stimuli which were congruent to both intentional and incidental processing conditions. Moreover, verbal intelligence was positively correlated with usage of incongruent stimuli which were processed incidentally in creative task. The results are discussed in terms of contemporary frameworks of information processing in verbal tasks.

Metacognitive Calibration

AbstractThe type of a recall task may substantially influence the effects of learning by retrieval practice. In a within-subject design, 54 university students studied two expository texts, followed by retrieval practice with either short-answer tasks (targeted retrieval) or a free-recall task (holistic retrieval). Concerning the direct effects of retrieval practice, short-answer tasks led to increased retention of directly retrieved targeted information from the learning contents, whereas free-recall tasks led to better retention of further information from the learning contents. Concerning indirect effects, short-answer tasks improved metacognitive calibration; free-recall tasks increased self-efficacy and situational interest. These findings confirm the assumption that the effects of retrieval practice depend on the type of recall task: short-answer tasks help us remember targeted information units and foster metacognitive calibration. Free-recall tasks help us remember a broader spectrum of information, and they foster motivational factors.
