Bilingual dual-coding theory and semantic repetition effects on recall.

A bilingual version of dual-coding theory was tested with French-English bilinguals who free recalled lists of concrete and abstract words repeated at different interitem lags. Repetitions involved the same words, translation equivalents, or same-language synonyms. The results extended previous findings and generally supported predictions from dual-coding theory and the independence storage hypothesis of bilingual memory: (a) Relative to single words, semantic repetitions (translations and synonyms) had additive effects on type recall even at short lags, whereas identical repetitions were less than additive at zero lag; (b) recall of identical repetitions increased more with lag than recall of semantic repetitions, so that differences between these conditions were diminished and sometimes reversed; (c) semantic repetition effects were weaker for synonyms than for translations, especially for abstract words; and (d) intrusion errors and pair recall were higher for translations than for synonyms, especially for concrete words at long lags.

Suggested amnesia and disorganized recall in hypnotic and task-motivated subjects.

Submitted 52 undergraduates to task motivation or hypnotic treatment. Ss were then given an amnesia suggestion for a previously learned list of categorized words. The number of words recalled and the extent to which they were recalled in clusters were compared before, during, and after lifting the amnesia suggestion. Results show that more hypnotic Ss than task-motivated Ss showed amnesia. Furthermore, hypnotic Ss, but not task-motivated Ss, showed less clustering during the suggestion than they did before or after the suggestion. The Ss who showed at least partial failure to recall during the suggestion were classified into 3 groups: (a) those who remembered but did not verbalize the words, (b) those who experienced amnesia as an effortful process involving distraction or forceful suppression, and (c) those who simply relaxed and experienced amnesia as an effortless process. A theoretical model is tentatively advanced to account for these data. (31 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Constraints on the effects of mood on memory.

In Study 1, pleasant and unpleasant personality trait words and abstract nouns were encoded in neutral mood and recalled in either induced depressed or induced happy mood, using 32 female and 32 male undergraduates assigned in equal numbers to 1 of the 4 conditions. Females recalled more pleasant than unpleasant words when in a happy mood and more unpleasant than pleasant words when in a depressed mood. Males failed to show this effect. Both sexes responded equally well to the induction procedures. There were no sex differences in pleasantness ratings of the words to be recalled. A prediction that differential effects of mood on recall would be greater for trait words than abstract nouns was not confirmed. In Study 2, everyday usage ratings by 36 Ss from Study 1 were obtained for the trait words from Study 1. Females gave higher usage ratings than males and, within the females, usage predicted the extent to which a word was preferentially recalled in a congruent mood state. Findings are discussed in relation to the associative network model of mood and memory, sex differences in depression, and cognitive vulnerability to depression.

Relationship between affect and memory: Motivation-based selective generation.

Two experiments examined the influence of anger and retaliatory motivation on memory for negative material. In the 1st study, 60 male undergraduates memorized words with positive, negative, and neutral semantic connotations. It was found that angered men who expected to retaliate against their provocateur recalled more negative words than other words, and more than Ss in all other affect and evaluation conditions. Angered men in the nonretaliation condition displayed no differences in negative word recall. The 2nd experiment investigated memory for details of a provoking experience. Angered men who expected to retaliate more accurately recalled the details of their provocation, but whether they were given information before or after provocation had no bearing on memory for these details. Results are discussed in terms of a motivation-based selective generation hypothesis for the relationship between anger and memory. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Studies in efficiency: Semantic generalization in schizophrenia.

This study examined the hypothesis that schizophrenics would generalize a conditioned GSR response relatively more to the homonym of a CS and relatively less to the synonym than normals. The specific prediction was that the difference in the magnitude of response to synonyms and homonyms (RS - RH) would be greater for normals than for schizophrenics. The Ss were 16 normals and 16 chronic schizophrenics. The synonyms elicited a larger response than the homonyms with the majority of normal Ss. The opposite results were obtained with the schizophrenics. An analysis of variance clearly supported the hypothesized interaction between the "normal-schizophrenic" variable and generalization to synonyms and homonyms.

A word-frequency cohort effect in young versus elderly adults' memory for words.

72 undergraduates and 72 elderly Ss (mean age 73.6 yrs) were tested for recall of 4 types of word lists that varied in terms of word frequency and datedness. "Popular" words had high frequency in both E. L. Thorndike's (1921) and H. Kucera and N. W. Francis's (1967) norms; "dated" words had high frequency in 1921 but low present-day frequency; "contemporary" words had low frequency in 1921 but high present-day frequency; "rare" words had low frequency in both norms. In both the sorting-recall and the standard multitrial free-recall tasks, the older Ss' pattern of list recall differed from that of the younger Ss. For older Ss, the feature of early high frequency promoted better recall (in the popular and dated lists) than did present-day high frequency (i.e., the contemporary list was recalled as poorly as the rare list). Results suggest a word-frequency cohort effect and indicate that high-frequency words from one's youth are particularly memorable, especially for elderly individuals.

Recall of pleasant and unpleasant words in depressed subjects.

In Exp I, 20 clinically depressed inpatients (mean age 39.9 yrs), 20 nondepressed inpatients (mean age 42.65 yrs), and 20 nonpatients (mean age 44 yrs) were shown a word list containing pleasant and unpleasant words. One-half of Ss in each group were given free-recall instructions, the other half were asked to rate each word on a pleasantness scale prior to recall. Results show that only depressed Ss given free-recall instructions recalled more unpleasant words than pleasant words. In Exp II, 30 clinically depressed inpatients (mean age 39.33 yrs) were shown a word list consisting of either (1) pleasant and unpleasant words, (2) unpleasant words, or (3) pleasant words. Results show that only Ss receiving the mixed list recalled more unpleasant than pleasant words. Findings support the hypothesis that depressed Ss selectively process unpleasant words and that this processing is at the expense of attention to pleasant words.

Output interference in long-term memory.

Reports 2 experiments, with 70 and 140 undergraduates, concerning the role of output interference on the recall of organized material. Groups of Ss received blocked presentation of a 49-item list consisting of 7 items in each of 7 categories. At recall, the category name served as the retrieval cue. In Exp. I, a 20-sec recall interval was allowed for each category and 10 Ss were assigned to each group. In Exp. II, this interval was increased to 90 sec. and 20 Ss were assigned to each group. Results of both studies indicate that the number of words recalled from a category is dependent on the position of the category in the output sequence. In general, the earlier a category appears in the output sequence, the greater the number of words recalled from that category.

Conscious and preconscious influences on recall: Another example of the restricting effects of awareness.

2 groups of 34 and 36 Ss were asked to recall a list of 27 words—10 associates to the word cheese, 10 unrelated words matched for frequency, 6 buffer words, and the stimulus word "Cheese," embedded in the center of the list. The pattern of recall was studied (a) before "Cheese" was recalled, (b) after "Cheese" was recalled, and (c) when "Cheese" was forgotten. As predicted, a significantly greater number of associates than control words were recalled before "Cheese" was recalled; after "Cheese" was recalled and when "Cheese" was forgotten, an equal number of associates and control words were recalled. Findings were substantially the same in the 2 groups of Ss. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The role of cutting in the evaluation and retention of film.

Two experiments with 96 undergraduates investigated the effects of cinematic cutting on viewers' evaluation and retention of the film and whether the cuts could be recalled. In Exp I, Ss viewed films of 8 common events, evaluated these films, and recalled the depicted activities. Exp I indicated that (1) films with cutting were preferred over uncut films and were judged to be more interesting, more active, stronger, and quicker than films without cutting; (2) cutting influenced simpler films more strongly than complex films but did not influence Ss' organization and recall of the depicted activities; and (3) the number of cuts was not accurately retained. Exp II, in which Ss were instructed to attend to the structural characteristics of each film, showed that Ss accurately recalled the number of cuts but remembered fewer activities.

Topic structure representation and text recall.

Tested the hypothesis that readers represent a text's topics and their interrelations as they read and then use those representations to access information about each topic. In 2 experiments, 222 undergraduates were required to read and free recall an expository text of approximately 1,100 words in length. Exp I manipulated both the order of topics in the stimulus text and whether the introductory paragraph stated the topics and their organization. It was found that Ss recalled information about fewer topics if the topics were randomly ordered and the introductory paragraph was uninformative than if topics were logically ordered or if the introductory paragraph was informative. Differences in recall of topics accounted for much of the variance in overall recall and recall errors. Exp II examined the effects of the presence or absence of topic sentences and of variations in the physical marking of paragraph boundaries. Findings show that Ss recalled information about more topics if the text contained topic sentences than if it did not. Results are consistent with the hypothesis that readers use a representation of a text's topic structure to guide recall. (40 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of number signals on reading and recall.

Examined the influence of number signals (i.e., numbers or number words preceding important textual information) on text recall. 120 undergraduates read and recalled 2 texts containing 10 target sentences each. Reading times were recorded for each target sentence. For half of the Ss, the target sentences were preceded by numbers indicating their organization; for the other half, the target sentences were not signaled. Half of the Ss completed a free-recall task, while the remainder completed a cued-recall task. Results indicate that Ss read target sentences more slowly if they were signaled than if they were unsignaled. Ss' recalls of target information followed the text organization more closely if the sentences were signaled. Signaling aided free recall of target sentences, but had no effect on cued recall. Results demonstrate that number signals directed attention to the sentences they marked, led to better encoding of the organization of target information, and influenced the process of recalling the target information.

Level of processing as a determinant of hypnotic hypermnesia.

Reconceptualized the distinction between those situations in which one can and cannot expect to observe hypnotic hypermnesia using the levels-of-processing theory of memory, as proposed by F. I. Craik and R. S. Lockhart (see record 1973-20189-001). In Study 1, 20 hypnotized Ss (high hypnotizables), relaxed/motivated Ss (high hypnotizables), and 20 simulating Ss (low hypnotizables) processed lists of words matched for meaningfulness and imagery value at "deep" or "shallow" levels. As predicted, the hypnotized group recalled more deeply but not more shallowly processed stimuli than the control groups. In Study 2, these findings were replicated with 30 undergraduates using improved experimental procedures and were extended to a recognition situation. In neither study was the observed hypnotic enhancement accompanied by an increment in errors. It is concluded that cognition at the time of processing is critical in rendering a stimulus amenable to hypnotic hypermnesia.

Differential recall as a function of mood disorder in clinically depressed patients: Between- and within-subject differences.

In Study 1, 23 depressed outpatients (aged over 60 yrs); 23 controls matched to the depressed group on age, sex, education, and SES; and 23 undergraduates rated trigrams as liked or disliked and were asked to recall a portion of these after a study period. Results show that depressed Ss recalled more trigrams they had disliked than ones they had liked. Both control groups had the opposite pattern, but undergraduates recalled significantly more trigrams than did older Ss. In Study 2, 20 of the 23 depressed Ss from Study 1 were administered different trigram packets at the middle and end of therapy using the same procedure. Results show that the change from a depressed to a nondepressed state across therapy correlated with a change from the superiority of disliked trigrams in the recall to a superiority of liked trigrams. It is suggested that this simple differential-recall procedure can be used as a moderate measure of the continuum of depression and success in therapy.

Encoding of personal information: Self–other differences.

Self–other differences in processing personal information were investigated in 5 experiments with a total of 53 undergraduates by having Ss make self-referent (describes you?) or other-referent (describes experimenter?) ratings of personal adjectives. Results indicate that self-ratings were consistently judged as easier to make, and Ss always placed more confidence in these judgments. An analysis of rating times showed that only adjectives with long rating times were recalled for the unknown-other-referent task (Exps II and III). In contrast, the recalled words for the self-referent task had very short rating times. This difference is explained via a "2-process" interpretation. Unknown-other-referent processing involves a relatively inefficient rehearsal or effort strategy, whereas self-referent processing involves the self as a highly organized and efficient schema. The effects of familiarity on other-referent processing were examined in Exps IV and V. A model of other processing is formulated to account for the observed changes in processing information about a familiar other.

The self as a mnemonic device: The role of internal cues.

Two studies with 48 undergraduates examined the contention that the self-reference effect occurs because the self provides a set of organized internal cues in the form of personal experiences that can mediate recall. The 2 properties—constructibility and associability of internal cues—are also important to the self-reference effect. S-generated cues composed of personal experiences representing the internal self were compared with cues composed of names of body parts representing the external self (Exp I). The body-part cues were more easily reconstructed by Ss at recall than were personal-experience cues. Nevertheless, trait words were better recalled after being related to personal experiences, because trait words and personal experiences were easily associated. In Exp II, concrete nouns were presented rather than trait words, and no difference in recall using the 2 types of cues was found. This occurred because concrete nouns can be easily associated with either personal experiences or body parts. (30 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Role of affective meaningfulness and self-concept in the verbal learning styles of White and Black children.

White and Black 5th graders, representing 2 social class and 2 self-concept (Piers-Harris Self-Concept Scale) levels, recalled nouns which they had prerated for likability in a multitrial free recall format. While self-concept failed to have any noticeable influence on the total sample, it interacted significantly with race. As predicted, the high self-concept White Ss recalled positively rated words more readily than negatively rated words, while their low self-concept peers showed no memory predilection. Although the low self-concept Black Ss also reflected no preference for their affective evaluations, the high self-concept Black Ss showed a greater propensity to recall their negatively rated words. Social class had a negligible effect on affective learning styles. (15 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Organizational and retrieval processes in person memory: An examination of processing objectives, presentation format, and the possible role of self-generated retrieval cues.

Examined memory for behavioral information under conditions in which the number of target persons and the number of behaviors pertaining to each target person were simultaneously varied. 256 undergraduates recalled more of the behavioral information when given a general impression set than when given a memory set, when the information was presented blocked by person than when it was presented randomly, and when they were tested immediately rather than after a delay. Impression-set Ss recalled more behaviors per person than memory-set Ss when the information was presented in a blocked format. However, they recalled more individual target persons and more behaviors per person when the information was presented in a random format. Results suggest that the specific nature of processing objectives and the constraints imposed by presentation format need to be considered carefully in developing future theoretical models of person memory. The role of self-generated retrieval cues and the possibility that there are 2 conceptually distinct types of retrieval are discussed.
